Legal and contractual relations are but briefly discussed, as these subjects are fully treated in many val- uable works to which it is intended that these notes shall serve simply as an introduction. The principles of personal and ethical relations, while discussed in somewhat greater detail, are but inadequately treated on account of the lack of space. The preparation of specifications is discussed in greater detail as less published matter is available on this subject. The young man who enters any vocation comes in contact with and is sometimes employed by men who disregard professional and business ethics and do many things which, while perhaps in entire conformity with law, are far from the ideals of ethical conduct. If a young man has given no thought to moral and ethical principles, he is apt to assume that such principles are cant and that unethical methods and actions are common to all those in business and professional life and are therefore essential to his personal success. He should therefore be advised and assured of the facts in the case : that the best and most successful men in every business and profession are those men of high ideals whose honesty and integrity are unquestioned and whose character and repu- tation are regarded as the greatest and most valuable of their posses- sions. The author has uniformly advocated the "square deal" in the re- lations of the engineer and architect with the contractor and with all others with whom they may have relations. He believes that honesty, integrity, and fairness accord the best possib^.e basis for practical, pro- fessional and business life and are not simply principles to be acknowl- edged and ignored. He believes that the appreciation of these prin- ciples will lead to the highest type of work, the most economical con- struction, and the greatest professional satisfaction. In the study of specifications, little advance can be made by an at- tempt to prepare at once an elaborate specification for a complicated engineering structure of which the student knows nothing. In such a case, all that can be expected is the copying, with perhaps some small changes, of similar specifications prepared for some proposed or com- pleted work, and such practice will be of little value. iv Preface In the teaching or study of any subject, success comes through the abihty of the teacher or student to simphfy the subject so that its basic principles may be easily comprehended ; the greatest difficulties follow an attempt to attack the subject in a too complicated manner. The principles and elements of specification writing should be ac- quired through the actual preparation of specifications for sim.ple ma- terials or elements and for simple processes or structures. All work should be simplified as much as possible ; it must be so defined and illus- trated that the problems involved will be clearly comprehended ; it must be analyzed in detail so that every phase and item shall be seen and appreciated. If this can be successfully accomplished with simple ele- ments of material or construction, it can then be applied to more com- plex subjects, which are sim.ply a combination of such elements. In the preparation of specifications there is no more important matter than the use of good English. A correct thought improperly expressed is often as misleading as though the idea itself were in error. A clear description of simiple subjects should therefore be the object of prehmmary practice. In m.any cases all the specifications essential are mcluded in a letter, and mxany contracts are actually consummated by an of¥er transmitted by letter and by a letter of acceptance. By practice along the lines indicated, the young engineer will at least acquire an intelligent method of procedure, and if the method is understood, the professional application may be safely left to "individual initiative. Tiic analytical system suggested for the preparation of specifica- tions has been used by the author for nearly thirty years, and is believed to afiford a safe ana logical method for the preparation ot these papers. This book vvas lirst issued in the spring of igi6 for the author's class and for private circulation. Of those to whom copies were sent, constructive criticism was requested. A number of valuable sugges- tions were received, and the book has been rearranged, revised and en- larged in this first edition. The author is aware that there are still numerous changes and additions that can be made to advantage, and hopes to make material betterments in future editions. He will be glad to receive further constructive criticism and suggestions from engi- neers, architects, contractors, teachers or others interested in the sub- ject. AcknozvJedgmcnts The author desires to acknowledge his indebtedness to the techni- cal press and to the many valuable technical books and articles that have appeared on the various subjects discussed. To these he undoubtedly Preface v owes many of the ideas expressed in this book. These ideas have how- e\rer been substantiated by an active personal contact with professional and uusiness life. It has been his aim to credit the source of informa- tion whenever such source could be distinguished, for he claims little new or original except as to treatment and arrangement. The thanks of the author are especially due to Mr. L. R. Balch for many suggestions, for aid in the preparation and proof reading of the text, and for supervision of its publication. Especial acknowledgment for valuab-e advice is also due to Dean F. E. Turneaure and C. V. Sea- stone. Numerous others have made valuable suggestions which have been utilized so far as practicable; among these should be mentioned Messrs. Charles H. Paul, E. K. Shnable, H. S. R. McCurdy, H. L. Gar ner, F. W. Scheidenhelm and Professor C. L Corp. Madison, Wis., Sept., 1916. D. W. M. PREFACE TO SECOND EDITION In the first edition of this book. Chapter IX on Contracts was purposely greatly abbreviated on account of the many excellent works available on this subject, some of which should be in the library of every engineer. In its use as a text book, it has been found by the writer and other instructors to be inexpedient to refer the student to other works except in special cases. It therefore seems desirable to expand the subject considerably and to treat more in detail the various features of this important subject. The chapter on Contracts has therefore been entirely rewritten, enlarged and expanded by Mr. Frank Jenks of the Wisconsin Bar. In Chapter II, an inventory of personal characteristics, modi- fied from an outline prepared by Dean A. A. Potter of Purdue University, has been added as a basis for character study. A sec- tion on financial success has also been added, showing the improvi- dence of the average man, the consequent necessity for the early formation of habits of economy, and the fundamental basis of safe investments. The important relations of engineering to business and finance are also briefly discussed. Numerous other additions and corrections have been made throughout the text. The very kind reception of the first edition is greatly appre- ciated by the Author who hopes that this second edition will be found even more useful. Madison, Wis., Sept., 1920. D. W.

The municipal engineer and contractor should understand those municipal laws which affect municipal works and which both limit and control municipal activities. The hydraulic engineer should un- derstand the laws of riparian ownership and those governing the acquiring of water rights and the construction of water power, irri- gation and drainage projects, and the legal requirements of naviga- tion, logging, fishways, etc. The mechanical engineer should un- derstand something of patent laws and of the various other laws which affect his specialty. In each branch of engineering there are certain legal relations the knowledge of which is indispensable to successful engineering practice. Laws are so manifold that no lawyer in general practice can be thoroughly informed on all of their branches, and the engineer in practice frequently becomes better informed on those laws which affect his own specialty than does the lawyer in general practice. In matters of moment, expert legal assistance should be employed, as specialists in the law are as essential for a proper knowledge of special legal requirements as are specialists for the best practice in engineering. § 6. Ethical and Personal Relations. — A proper appreciation of the essential moral and ethical relations of the individual is difficult to acquire or to impart, yet there are no subjects so important or so inter- esting as those which deal with the realities of life and the proper re- lationship of the engineer to his profession, to business, to the pub- Legal Relations 13 lie and to his fellow men. The relations of man to man are but poorly governed by the law, and a law-abiding man may be a poor citizen and undesirable as a friend or neighbor. The per- sonal conduct of man in the manifold and intimate relations of social business and professional life must be governed by more generous and equitable rules than those provided by the statutes, which can furnish only regulations which will perhaps give equitable results in the ma- jority of instances but can govern only some of the major points of contact. A man may be selfish, unfair, untruthful, narrow, egotistical, tricky, and even to a considerable degree dishonest, without fear of the law ; but the individual in whom such characteristics predominate is a detriment to himself, to his friends, and to society. Every individual acquires in his youth, from his parents and intimates, a certain knowl- edge of moral and ethical principles which have usually a most impor- tant and lasting effect on his view of life. This knowledge is usually fundamental and needs elaboration and thoughtful consideration in its extension to the greater affairs of life. The well established principles of social business and professional ethics sometimes seem disproved by the individual experiences of the young engineer who may see apparent prosperity follow a disregard of these principles. It would indeed be unfortunate if he has not been fully assured that such results are only apparent and that the greatest and best success can come only with the highest conception of duty. Most practicing engineers and business men recognize the fact that a true appreciation of ethical relations is fully as important for success as technical knowledge or business ability ; that irrespective of morals or religion, honesty is in reality the be^.t policy and must be ex- ercised in all social, business and professional relations in its broadest sense. To do as he would be done by, is the simplest, broadest and the most complete ethical standard for the individual. A sincere regard for both the legal and the moral rights of others, whether associate, employer, client, workman, contractor, competitor or the public, is a necessary attribute to the greatest success. All honest and conscien- tious effort toward personal advancement is commendable, but the rights of others must be consistently observed. The establishment of a personal, business or professional reputation for honesty and dependa- bility is a greater asset than any immediate profit from unethical ac- tions. These conclusions have stood the test of long practical experi- ence in business and professional life. As responsibilities increase, as fiduciary relations become estab- lished, as the work of the engineer attains a higher professional charac- 14 The Engineer and His Education ter, there becomes involved not only conscientious honest and energetic effort toward personal professional advancement, but also obligations toward the profession and toward humanity, even at the sacrifice ot personal interest. The term "professions" includes those callings which involve in their practice high ideals, great energy, distinguished ability, correct and logical thought by means of which effective results are obtained, through efficient application of technical knowledge and proper or- ganization. Such callings also involve a high conception of personal honor and personal obligation not only toward all with whom the practitioner comes in personal contact but toward the profession, the state, the nation, and toward humanity. The engineer must understand therefore, not only the elements necessary for personal success but also those requirements neces- sary for the realization of the higher ideals of professional success.

CHAPTER II SUCCESS IN THE ENGINEERING PROFESSION § 7; Personal Success. — Success in life, like success in the con- struction of an engineering structure, requires a good and a proper foundation on which to build. Success is measured by many men in many ways. The best success is not measured by great wealth or great power nor by the greatest amount of idle pleasure, for the pursuit of any of these single purposes does not result in the greatest happiness which is perhaps the truest measure of the greatest individual success. The greatest success results from a well balanced life and should usually include : First: Suitable friends and family relations; for the greatest suc- cess does not come with solitude. Second: Sufficient income for the comfort of the individual, his family and dependants, and to permit him to help those philanthropic movements in which all should take part. Third' A good personal, professional and business reputation hi his life work. Fourth: The respect of his friends and associates. Fifth: Self-respect or the personal approval of his own conscience, resulting from the proper observance of personal religious and ethical convictions. Whatever may be the ideal of the individual, if it be worthy of the name of success, its attributes are health, native ability, character, edu- cation, experience and opportunity. Each is partially independent and partially dependent on individual effort, and each can be improved and strengthened by the exercise of care, perseverance and energy. Character, while partially hereditary, is more largely due to the influence of family and associates, and to education and personal cultivation. That the age and thought of the times largely control character is undoubtedly true, yet no age or nation has been so de- generate that it has not developed some men of high ideals and of character creditable in any age. No high professional standing is ever attained without properly developed character; it is like the internal mechanism of an important machine, unseen but essential to the proper and correct exercise of its highest functions, It is the Personal Success 17 main spring of the best success and is susceptible of great modifica- tion and improvement by individual effort. No great success is possible without health. Ill health draws the attention of the mind to the condition of the body at the expense of the capacity for concentrated thought, affects the ability for energetic effort and weakens the power of resistance and personal capacity. Clean liv- ing, healthful exercise and mental relaxation are therefore not only de- sirable but essential for both personal, business and professional success. A knowledge of personal and public hygiene and sanitary require- ments is necessary not only for their influence on personal health but also on account of the engineer's control of the health of others in his public relations and in his private relations in tht factory and in the field. The degree of native ability possessed by the individual is un- doubtedly a considerable element of success if properly utilized and developed. It cannot take the place of hard and conscientious work and continuous effort. Most so-called "men of genius" will admit that their success is due more to hard work and continuous effort than to native ability. Greater success is due to the personal exer- cise of will power that concentrates the efforts on the end in view and utilizes such ability as is possessed by the individual than to the half cultivated spasmodic exercise of so-called genius. The indi- vidual who fMDSsesses both great native abilitv and the ability for sus- tained concentrated effort has opportunities of high order. In all cases, the development of ability is dependent to a ^arge degree on individual endeavor. Education and experience are to a considerable degree the re- sults of opportunity, but they are still more largely acquired through individual exertion. The lack of college or university opportunities is no bar to the individual who is willing to exert continuous and unremitting effort in the acquisition of an education. The schools and instructors are an aid, not a necessity : and such aids shouM be utilized when available, but they can be d'spensed with when ne- cessity demands, if replaced by energetic, vigorous and forceful ap- plication. Experience is best acquired by personal observation, but the re- corded practice of others is a source not to be neglected. Opportunity may freely come to some, but it is created by tnany. The lower rounds of the professional ladder are congested with throngs of young men half educated and half prepared, clamor 18 Success in Engineering ing for opportunity, while the higher positions for which they are un- suited are often only poorly filled and waiting for the proper person. There are few professional lines in which an able, well edu- cated, well informed man of high character will not find opportunity waiting and anxious for his coming. Strenuous, unremitting labor and continuous, conscientious eflfort are the prices of success. § 8. Factors of Success Must Be Recognized. — The attributes described in Section 7 must be both acquired and properly exercised ; they must develop in the individual those certain habits of industry and traits of character which are demanded of professional and business men by their employers, clients and associates and without which the individual will be at a great disadvantage in the practical affairs of life. The successful solution of any problem depends on both a comprehen- sive knowledge and a proper application of all of the factors on which the solution depends. In order therefore to succeed in the various problems of professional and business life it is no less essential that all of the factors of success shall be duly appreciated and given the pro- portionate weight which their importance demands. Much might be written on any of many factors of success, but only a brief discussion on some of the most important seems warranted. Common sense and judgment must extend the list and supply further details. If a limited discussion is not sufficient to convince a man of the essential nature of the characteristics discussed, further elaboration "would result only in a waste of both space and time. The man who will win success will be able to recognize its essential elements without extended discussion. § 9. Opinions of the Engineering Profession. — For some years a joint committee on engineering education from the national technical societies of the United States has been investigating engineering edu- cation, and by an arrangement with the Carnegie Foundation for the Advancement of Teaching, a detailed investigation has been undertaken to determine the qualifications necessary for success in engineering work. In the spring of 1915 letters were sent to the members of all of the national technical societies requesting individual opinions on the essential characteristics of an engineer. A report* was made in the spring of 1916 as a result of this investigation, in which the essential factors were summarized into six groups which were numbered in the order of their importance as determined by the frequency of their oc- currence in about t'.soo replies. On the basis of this preliminary work *Report by C. R. Mann. Proc. Am. Soc. C. E. Feb. 1916. opinions of the Profession 19 a new letter was sent out to the members of the society asking for further consideration of the six characteristic groups previously out- lined. To this letter 5,441 replies were received sufficiently definite for classification. From these letters the most probable values of the rela- tive importance of these groups of qualities were computed with the following results, which seemed to indicate a rather definite ideal of the professional engineer as to the characteristics necessary for the greatest success :* Revised and Original Ratings Revised Original Character, integrity, responsibility, resourcefulness, in- itiative 24.0 41.0 Judgment, common sense, scientific attitude, perspective 19.5 17.5 Efficiency, thoroughness, accuracy, industry 16.5 14.5 Understanding of men, executive ability 15.0 14.0 75 87 Knowledge of fundamentals 15.0 7.0 Technique of practice and of business 10.0 6.0 25 13 100 100 It must not be understood that any single arrangement of these six groups actually indicates the views of professional men as to the essen- tial characteristics of an engineer for each and every position, for it is manifest that each individual should have the essential characteristics developed to the greatest advantage for the particular position which he occupies. Each man must be capable of a proper performance of his duties, and his lack of any essential characteristics is necessarily fatal to his success. The metals used in engineering construction are in most cases alloys and consist of a combination of various elements some of which are essential and some of which are considered as impurities. Never- theless each element whatever its character and amount has a particu- lar influence on the character of the alloy. If any one is missing it may change entirely the characteristics of the alloy and make it unfit for some particular use. For the greatest usefulness in any particular place, each element must be present to the extent needed. In the same manner a man may be useless in an engineering position, even though his character, judgment, efficiency and understanding of men may be highly developed, unless he has a proper knowledge of the fundamen- tals of engineering science and the technic of practice ; and yet in all professional positions which involve fiduciary relations (and there are willing to attempt those undertakings for which he has been amply pre- ♦What is an Engineer. C, R. Mann. Eng. Rec. Vol. 74, p. 10. 20 Success in Engineering practically no positions which do not) there can be no doubt that char- acter, judgment, efficiency and understanding of men are of much greater relative importance in the attainment of the greatest profes- sional success, if it can be stated that one essential is of greater im- portance than another where all are absolutely necessary in some degree. § 10. Judgment. — The few years spent in a technical school can- not give a profound knowledge of any of the subjects studied. The fundamental principles of those sciences on which practice is based must be acquired, but these principles must usually be further investi- gated and their relation to practical things more fully determined when the engineer comes to apply them to the actual work of design and con- struction. Methods of investigation and of calculation must also be further considered and judgment and skill in their use acquired when their application to concrete problems becomes important. In the class room the conditions of the problem are usually distinctly stated. The factors that enter into it are definitely assumed. The theory that ap- plies to these conditions is before the student. The application of the principles and the solution of the problem under such conditions are not difficult because the uncertainties are eliminated. In the field the circumstances are very different. Here the engineer must determine for himself the correctness of the theory which he applies ; he must determine the factors which actually enter into the problem and he must be certain that there are no other considerations which will affect it and render the theory inapplicable or the solution incorrect. Ac- curacy, thoroughness and speed become important in the field. On these functions depend not only the personal success or failure, which is important to the individual, but often the success or failure of the engineering work which may involve lasting benefits or loss of both life and property. The very keystone of successful engineering practice is judgment.' The development of judgment requires personal investigation, per- sonal consideration and personal conclusions, and should be based on a well balanced appreciation of both theory and practice. In the devel- opment of judgment the dicta of instructors, the statements of text books, and the opinions and conclusions of others must be questioned, and can be accepted only when they satisfy the fullest inquiry and analysis. In other words, the engineer, in order to develop his judg- ment, must learn to think for himself, to form and hold opinions of his own, and to base those opinions on a substantial, comprehensive and thoughtful consideration of both theoretical principles and practical re- sults. Self Knowledge . 21 Judgment may be based on practical experience and is then ap- plicable within the limits of that experience. When however judgment is based on a correct theory which has been substantiated by a wide range of practical experience, it is capable of being applied to a much wider field than when based on practice only. It is a^.so apparent that judgment must also be based on a correct perspective of the individual's personal attributes and aptitudes, for if the individual deceives him- self through his own personal traits his judgment will be unsound. § II. Self Knowledge and the Understanding of Men. — Stu- dents and others in college or out who have in a large measure pursued their studies and investigations more or less independently have small opportunity to compare their own ability with that of others who are proficient in the same line. No man has a fair opportunity for self- knowledge and an understanding of men until he is able to compare himself with others in the real problems of business or professional work. It is vital that the individual be able properly to estimate his own abilities in order that he may miss no opportunity which he is jus- tified in undertaking, and in order that he shall also avoid undertaking those things for which he is not qualified. There is perhaps no more difficult matter than adequate self-judgment. On the one hand a large proportion of individuals naturally over-estimate their own abilities, while on the other hand a considerable percentage fear to undertake new adventures for which they have received reasonably satisfactory training. Over confidence and an over estimate of individual ability will result in failures which are always embarrassing and sometimes seriously limiting to future opportunities. One who has shown false judgment in matters of moment commonly loses the confidence of those who have hitherto trusted him, and he is seldom entrusted with addi- tional problems of a similar nature until he has overcome by long suc- cessful service the record of his failures. A lack of the appreciation of one's individual capacity will lead to the loss of opportunities, which is also serious. People have confidence in those who have confidence in themseVes until they learn that the confidence is misplaced, and opportunities come to the greatest extent to those who believe and know they can accomplish those things which they undertake. A man is foolish who undertakes those things for which his knowledge and experience have not fitted him, for the chances of success under such conditions are too remote and the results of fail- ure are too serious. No less foolish is the man who fears to undertake things for which his education and experience have given him ample preparation and who, on account of the lack of self-confidence, is un- 22 Success in Engineering pared. The successful engineer must rightly weigh and appreciate his own limitations and must recognize his personal deficiencies and the meagreness of his knowledge ; and he must know that success is de- pendent on the proper use of his best ability and upon thorough, hard, conscientious and intelligent work. As pointed out in Section 2, the engineer, in his various rela- tions, will come in contact with many classes of men, with some of whom his interests and duties will be in accord and with others more or less at variance. For the greatest success he must be able to colloborate with the first group and harmonize and adjust his relations with the second group. Both objects can often be at- tained by a uniform courtesy and well developed sense of honor and fair dealing. An understanding of men is, however, highly essential for success. Every man has individual characteristics, inherited in part but modified and developed by his associates, sur- roundings, education, and experience, which give him his personal view of life and largely controls his thoughts and actions. It is only through contact with others that an understanding of men becomes possible. Both self-knowledge and an understand- ir-g of men may be facilitated by a consideration of the factors of character and personality, by a study of the effect of such factors on the individual, and by observation of the influence of surroundings and experience on human judgment. The following inventory of personal characteristics is modified from an outline prepared by A. A. Potter, Dean of Engineering at Purdue University and formerly Dean at the Kansas State Agriculture College. The use of this out- line, for the analysis of the personal characteristics of associates.- friends, and self, will assist materially in acquiring the habit of observation, in the formation of correct self-knowledge, and in the development of a correct judgment of others.

Personality. — The personality of the individual is of great importance and has a marked effect on his advancement. Good appearance, good address, proper self-confidence and self-respect, the evidences of intelligence and energy, the ability of proper expression, a proper consideration of the feelings and rights of others, mark the man for higher position and better things. Great ability and high technical knowledge and training may hold respect though the personality is un- favorable, but such respect is given not because of such personality but in spite of it. It is unfortunate that many young men who enter technical work acquire the idea, that as engineering sometimes involves the utilization of great strength and energy in pioneer investigations and construction, its practitioners should be not only strong and energetic but also rough and rugged, and that personal refinement is a thing rather to be dis- couraged than sought. No greater error is possible. The rough, strong, energetic character who ignores all personal discomforts either of himself or of others and drives construction work to successful completion in the face of great difficulties may be admired for the results which he achieves in spite of his roughness and disregard of dangers and discomforts. Such characters are bred in the construction camp in contact with hardship, ignorant labor and unfortunate frontier conditions, and they may be an important element in such classes of work ; but they are in no way representative of the ideals of the engineering profession. The social amenities of life, the polish of society, are not signs of efficiency but they are important means of lubricating business and pro- fessional relations. Personality 27 The field executive who is actually constructing engineering works is the ideal of the average young engineer, and is his idea of the per- sonification of the engineering profession. He fails to recognize that back of this, behind the actual construction work, is the brain that con- ceives and the mind that directs. Personal Appearance. — Personal appearance is also worthy of con- sideration, for impressions are based on the appearance, which is strongly indicative of character. Appearance is not simply a matter of dress but of personal attitude as well. A man should not be too mod- est or diffident, nor loud, overbold and familiar, but he should be quiet, confident, frank and businesslike. In dress he should be neat but not fastidious. He should endeavor to be inconspicuous, for con- spicuous dress usually shows unfortunate idiosyncrasies which need to be eliminated. The busy man has little time to give to the question of dress, but neatness and modest, quiet apparel, suitable to the work or position occupied, are indications of a well and properly balanced man. Punctuality. — Lack of punctuality is due to heedlessness, careless- ness, lack of consideration, or conceit, any one of which is equally ob- jectional and the possession of which is a serious detriment to the in- dividual's prospects. Punctuality is an essential qualification for suc- cess. An employee who is habitually tardy not only robs his employer of the time for which he is receiving compensation but frequently causes a consequent loss of the time of the employer or others whose services are of much greater value. A record for habitual tardiness is most unfortunate for it is a serious handicap for both present and future employment. In professional life, the man who habitually disregards the conven- ience of his associates and causes the loss of their time and patience by the lack of punctuality in meeting appointments shows the lack of a due consideration of the rights of others and will soon find that he is eliminated from such conferences whenever possible. He will lose much of the consideration and many of the opportunities which are essential to the best professional success. Attention to Business. — Not only should the employee be punctual in his arrival at his place of business but he should also devote his at- tention to his legitimate work during the hours set aside for that pur- pose. Office hours are comparatively brief, and arrangements for evening pleasures, a good story, the morning paper, the passing crowd and many other attractions which may catch the attention during busi- ness hours should be studiously avoided. They can well wait until the 28 Success in Engineering hours of work are passed, and if given attention during the time for business will require not only time which should rightly belong to other things, but will weaken the ability to concentrate the attention on the matter to which the time of the employee should be devoted. Willing- ness and cordial execution of orders and requests tend greatly towards promotion. Concentration. — The ability to concentrate one's attention on the immediate problem for consideration is a primary requisite for success and is a matter to which the young engineer should give his immediate attention and his best endeavor. This characteristic should be devel- oped early in life for it is fundamental to the accomplishment of any really valuable results in scholastic or business life. It should be in- culcated in the pupils of the common schools, impressed on the students of the college and university, and practiced by the individual in every phase of his later life. The ability to concentrate results in the greatest saving of time in school, in college, in the laboratory, the of- fice, the factory and the field. The man who can concentrate his at- tention on a problem will accomplish his work accurately and rapidly and wV\ therefore be of greatest value to himself and to his employer. The ability to drop a problem in order to receive directions, or on ac- count of various other interruptions which may occur, and: to at once take it up at the point where it is dropped, without loss of time or the reconsideration of the phases already examined, will result in the maximum conservation of time and the highest efficiency. The student often acquires the habit of concentration in solitude, and finds in the office, the factory or the field his attention distracted from his work by the confusion due to the presence of others and the work which is going on parallel with his own. He must train himself to ignore all that is around him and to keep his mind and attention strictly on his own particular work ; and when he is able to accomplish this, he will be surprised at the amount he can accomplish and at the rapid flight of time. The individual should ^earn to put his whole mind and energy on whatever he is doing to the exclusion of aU else, whether he be employed in working, playing or in sleeping. The man who cannot do his whole duty during his working hours because of thinking of the pleasure which awaits him, who cannot enjoy the present pleasures because his mind constantly reverts to his work, or who can- not properly sleep because of the business matters which constantly en- gross his thoughts, will make little progress in his work and is in dan- ger of business failure or mental collapse. The day's work should receive undivided attention, but in after hours the worries and difficulties of the day should be entirely laid Personality 29 aside and the time given to healthful recreation or to other matters of a beneficial nature. A sufficient time must be given to undisturbed sleep. Relaxation from arduous and continuous eflfort is essential to health, but a change in occupation is frequently as advantageous as an entire cessation from labor. Many men have found the pursuit of some science, collateral to their business, or in which they took a par- ticular interest, both stimulating and restful, and such pursuit has sometimes elevated its votary to higher things. The man who wastes time wastes opportunities. Relaxation should be a means, not an end. A young man who was playing billiards with Herbert Spencer, after running up a remarkable score asked Mr. Spencer's opinion of his play. "Young man," the philosopher replied, "I regard a slight pro- ficiency in billiards an accomplishment which every man might well en- joy, but such proficiency as you show bespeaks an ill-spent youth." There have been men who have seriously impaired their health by too constant application and by over work. They are small in number, however, and the danger of such excess is not great. There are more professional men who rust out than who wear out. Collaboration. — The individual should train himself to work in harmony with such associates as he may meet in any organization. He should eschew petty jealousies, fault finding and gossip. He should both avoid giving ofifense by careless words or actions and should en- deavor to overlook and ignore thoughtless speech or action on the part of others. A peevish or irritable disposition, and the habit of using sharp, bitter or inconsiderate language, unfits a man for successful association with others and deprives him of much of his usefulness, and conse- quently of the greatest value to himself. The habit of constantly tak- ing or giving offense, for the two traits are usually possessed in com- mon, is a serious handicap and will often eliminate the unfortunate possessor from important opportunities. Such a habit is so despicable that it frequently becomes unbearable and the greatest ability cannot compensate for the undesirable quaHty. Petty jealousy is equal'ly reprehensible. The man who cannot re- joice at the advancement of others but feels personallv as^s^rieved be- cause he has not received preferment will usually impede his own pro- gress. It is frequentlv true that promotion depends both on abilitv and in- dividualitv. and failure to secure the promotion which seems honestiv due should result in a serious consideration on the part of the indivi- dual of his own deficiencies in personal character, personal effort or 30 Success in Engineering personal ability. It should be a spur to greatest effort toward indivi- dual improvement for in general it is true that the man best fitted for a given position will be selected to fill it, for only in this way can the best results be obtained. Personal Bias. — That all men are to a greater or less degree biased in their judgment of themselves and of others and of all problems and conditions with which they come in contact is established by common experience. This bias is due to their individuality, their association, their local and individual experience, their education and special knowledge, and their personal interests. That this bias is pos- sessed by others and injuriously affects their judgment is easily recog- nized. It is more difficult for the individual to recognize such bias in himself. It is however most important for the engineer to recognize his own bias and to provide for it by elimination so far as possible, and by the same factors of safety which he applies to other uncertainties. To acquire this knowledge is perhaps the most difficult in the practical education of the engineer. Bias of Special Knowledge. — Special knowledge and a special ex- perience in a limited field of engineering, unless accompanied by a broad consideration and a considerable knowledge of collateral sub- jects, are apt to involve a prejudice or bias in favor of the application of such special means to the solution of all problems to which such means can be applied. The specialist naturally appreciates the full value of his specialty and the advantages that accrue from its applica- tion. Normally, he is less informed in other special methods of solu- tion of his problems, and is apt therefore to give undue weight to the advantages which he knows his own specialty to possess. The hy- draulic engineer is apt to overrate the advantages of water power and to underrate the contingencies of its construction and maintenance. The steam engineer is apt to over-estimate the value of the use of steam power in the solution of all power problems, and the electrical engi- neer, recognizing the advantages of electrical generation and trans- mission is apt to consider only electrical methods in power applications. In each case the advantages of other methods may be overlooked and the problem solved on individual preference and information, and not by the method which would prove the most advantageous if all condi- tions and methods were fully weighed and considered. In the correct solution of any problem, aM of the methods by which it can be solved are deserving of the fullest and most careful investiga- tion and consideration, for only bv such means can the best solution be found ; and the engineer who is desirous of securino: the best and most economical solution of the problem entrusted to him must give the Bias of Experience 31 most careful consideration to those methods with which he is least fa- mihar, for only by so doing can he hope to accomplish the best results. Bias of Personal Experience. — Personal experience should give the engineer his most useful and exact knowledge, provided such ex- perience is properly considered and digested. The fact that the knowl- edge so acquired is the most exact and valuable in his possession is apt to give it undue importance in the solution of other problems with which he has to deal. A successful engineering achievement, the prod- uct of ideas well matured, and of plans carefully prepared and well ex- ecuted, which has resulted in the creditable solution of an intricate problem, may rightly lead to the future application of similar methods and designs to problems of a similar nature. Frequently, however, there is a tendency for the successful designer to endeavor to adjust the conditions which prevail in a new problem so that they may be solved by the methods successfully adopted previously rather than to adjust the plans to meet the conditions as they exist. This tendency frequently results from a natural indolence to plan and adapt new methods to a problem where a successful solution, which has stood the test of practice, is immediately available ; and in many cases, the plans of a professional man bear evidence in themselves by the possession of certain common features of the source of their origin and the disincli- nation to consider each problem anew on its individual merits. Bias of Local Experience. — The normal conditions which obtain in any locality must of necessity modify the successful solution of every local engineering problem. A professional man who has successfully met the various problems as necessarily modified by local conditions within the range of his practice, has therefore to readjust his ideas and to modify his plans whenever he is called upon to solve a problem under circumstances where the local conditions differ to any considerable ex- tent. For example, the flow of streams differs radically not only on account of the difference in rainfall on the different drainage areas, but even more largely on account of the geological and topographical con- ditions ; and the engineer who has given special attention to one stream must use especial care when he considers construction which is to be carried out on another stream for which the conditions of flow may be radically different. In the matter of electrical supply for light and power, the demand per capita varies greatly in different parts of the same country and in cities of various sizes, even closely adjoining. Local factors greatly affect the cost at which work can be done. In the larger cities, the ex- istence of labor unions, which usually involve higher wages and shorter hours, and frequently more inefficient service, together with the extra 32 Success, in Engineering cost involved by street obstructions and other similar factors, ordi- narily greatly increase the cost of work over that for which similar work could be done in communities where the market for labor is not modified by such conditions, where traffic and obstructions are less serious, and where many other conditions are favorable to cheaper con- struction. It is a common observation that men familiar with only one set of these different conditions commonly fail to agree on the cost at which work can be done in some third community where neither has had actual experience. The city contractor who occasionally bids on work in the smaller communities of the country is usually unsuccessful as his experience with the high prices of the larger community preju- dices his judgment; and the contractor familiar with the work in the smaller communities commonly learns by dear experience the extra cost involved when he attempts to transfer his operations to the larger cities. These difficulties can be overcome by freeing the mind of purely local influences and by a detailed determination and considera- tion of the new conditions. Bias of Personal Interest. — It is important that the engineer should free himself as far as possible from the bias of personal inter- est which is a constant menace to sound judgment. No matter how conscientious a man may be or how much he may endeavor to arrive at judgments which are thoroughly sound, he is constantly in danger of not attaining the results desired if his personal interests are in any way involved. The engineer who is out of employment may, on account of his necessities, be greatly tempted to accept employment or commissions which are entirely beyond his experience or ability. Reports on special projects are often unduly optimistic for the reason that the engineer making the report is unconsciously influenced by the fact that a favor- able report will mean the prosecution of the project and his employ- ment in its design and construction. An engineer having a patent for some methods or process by which a problem has been satisfactorily solved is constantly in danger of ad- vocating this method, when it is at all applicable, and this from no dis- honest motive but on account of the fact that he has become so im- pressed with his favorite plan that he gives it a value to which it is seldom entitled. It is essential therefore that the individual endeavor to eliminate so far as possible any personal interest which he may have in the problem, except the interest of its correct solution. If its solu- tion on certain lines involves a profit to himself, such profit can be of only the most temporary and unsatisfactory character if it does not also involve the greatest possible success. Bias of Association 33 Bias of Association. — Almost every problem is capable of a va- riety of solutions although there is only one solution that can be the best when all things and matters are considered. Almost every ques- tion can be regarded from several points of view, and the correct an- swer is not always clear or evident. Association will normally estab- lish the point of view from which the individual will consider any question which is called to his attention. The most common exercise of this tendency is found in the unfair treatment of contractors by en- gineers who are employed to plan and supervise the construction of en- gineering works. There is a constant tendency to inflict, unjust re- quirements, and to require unwarranted expense especially in meeting contingencies which have not been anticipated by either party and which therefore could not have been included in the contract. The en- gineer is too apt to see matters entirely from the view point of his client and to fail to exercise that impartial judicial attitude that his professional position demands. In work of appraisal where a municipal corporation contemplates the acquisition of the property of a public utility, the engineer is al- most certain to assume the point of view which is most favorable to the side which he is called upon to represent. This may not result from any desire on his part to be unfair or biased, but is normally what is to be expected from the action of the human mind. Those who have served as chairman on boards of appraisal to which they have been selected by the agreement of both sides, and have consequently been unbiased on account of their appointment, have frequently ob- served the radical differences of opinion which have obtained among their colleagues whom they knew to be men of great ability and of the highest integrity. Most men who have engaged in this class of work, after the com- pletion of the appraisal and after the heat of the argument has faded away, recognize the same tendency in some of the ideas and opinions which they have previously held and which at the time had their com- plete endorsement and were the results of their most profound convic- tions. A peculiar result of this normal attitude, which is often appre- ciated by men engaged in such work, is that when they are" endeavoring to be entirely fair and equitable in their findings and appreciate their own inclination to bias in these matters, there is a proneness at times to rather overdue the matter and to consent to findings that are more or less unfair to those whom they represent. This is usually, however, a minor matter and does not vitiate the general proposition that in the main the tendency is to favor the client unfairly, but, it emphasizes the fact that the fair-minded man is not always able to bring in an equi- 34 Success in Engineering table finding in the face of his association and the personal proclivities of those by whom he was selected. The same tendencies are more fully emphasized by the expert wit- ness. There the personal bias of the witness is often accentuated by the endeavor of the other side to confuse or confound the opinions ex- pressed. In some cases these idiosyncrasies are so pronounced and are carried to such an extent as to give even the appearance of dishon- est intentions, to which they are sometimes so closely related as to be almost indistinguishable and may grade from mere prejudice to actual dishonesty in many lines of engineering work. § 13. Financial Success. — The test of the practical value of edu- cation is its successful application to the affairs of life, and the education acquired by the large majority of men, measured by its effect on their financial success, is of little worth. Few men are fitted to shape their own affairs for their own best interests. The statistics, compiled by the American Bankers Association, given in the accompanying table, show the fate of one hundred young men, 25 years of age, strong, vigorous, able to w^ork and who should be able to save money to provide for their advanced age and the future of their families. The number that succeed in so doing is pitiably small. FATE OF ONE HUNDRED MEN— STRONG AND VIGOROUS AT TWENTY-FIVE YEARS OF AGE (Compiled by American Bankers' Asso.)

Less than six percent of those v/ho die after 75 leave sufficient means to defray their funeral expenses. Financial Success 35 There are many causes that leave this great majority of men pen- niless in their old age. Misfortune, entirely or largely beyond the control of the individual, will account for a small percentage of these cases. Poor business judgment will account for a few more. In the great majority of cases, however, the causes are the entire lack of foresight, the lack of appreciation of the necessity of early accumu- lation and the increasing difficulties of saving later in life. The desires and apparent necessities of today make saving, from limited incomes difficult and unpleasant. With advancing age fre quently comes the necessity of greater expenditures, not always offset by relatively increased income, which renders saving doubly difficult if the saving habit has not been cultivated. There are few men who cannot, at least by strict economy, set aside something from their monthly earnings and such a habit should be acquired early. Such savings should be safely invested so as to immediately become active m accumulation. In many cases this can best be done by investing in life insurance for the regular demand for the annual, semi-annual, or quarterly premiums will often assure the setting aside of the neces- sary amounts by those who would otherwise expend their entire income on their immediate desires and necessities or make unsafe investments and ultimately lose their entire savings. Statistics show that while only four per cent of the incomes of the people of the United States is expended in life insurance premiums yet 87 per cent of all estates left in the country consist solely of life insurance. The Accmmilation of Savings. — Few realize how rapidly money accumulates when put out at interest. The following table gives the details of the accumulation of a continuous saving of ten dollars per month placed at interest at six per cent.

If this saving is continued it will equal $6,400 in twenty-four years and $15,000 in thirty-six years. While such an accumulation is not wealth, it will assure the individual, who starts such an account before twenty-nine years of age and continues such a course of saving, a greater independence at sixty-five years of age than is ordinarily possessed by 84% of the men alive at that age, and may represent the difference betwen comparative comfort and poverty and possible distress. Principles of Investments. — It is estimated that over $500,000,000 per year are lost by investors, in the United States, through projects that are either purely fraudulent or so speculative as to be little better than swindles. Statistics show that 97 per cent of all corporations organized fail within three years after their organization. It is evident that much of the money saved, often by considerable self- denial and self-sacrifice, is lost by injudicious investment. Such in- vestments are usually made with the hopes of comparatively large returns, which hope is not only unrealized but often the investment itself is lost. It follows that a safe investment at low rates of inter- est, absolutely assured, will in the majority of cases yield better results than can be secured by such investments as are commonly made by men imfamiliar with the risks involved. For these reasons the young or inexperienced investor would do well to place his earnings in life insurance, in the savings bank, or in government or municipal bonds, where the interest though low is certain and the principal is safe. With some business experience, reasonable safety may be assured and better interest obtained by the purchase of high grade bonds, mort- gages, and preferred stocks which pay from five to seven per cent. While "bonds" are regarded most favorably by the investing public, it should be understood that the term means little and that a bond may not be as safe or as valuable as a note, a preferred stock, or a common stock, the value depending upon the bond provisions, on the security behind it, and upon the management of the property. Buying securities is much like making any other purchase, the best protection to the purchaser is the reputation, character, and expe- rience of the investment company from which the purchase is made. Except when buying from banks or investment companies of un- doubted high standing, the purchaser would do well to consult some banker in whom he has confidence or write for information to one Principles of Investments 37 of the standard investment periodicals or to the financial departments cf some of the reliable magazines which undertake to furnish financial mformation. Business enterprises are undertaken for profit, not for charity, and investors are asked to purchase securities because the money is needed or desired for business or for speculative purposes. The reason for the issue and sale of any security, bonds, notes, preferred stock or common stock, is to secure money for some busi- ness enterprise at the lowest possible rate of interest, when the financial conditions of the country and the risks involved are considered. The returns offered on any security are as a rule only such as are thought to be necessary to secure the funds needed, and the amount of interest is in reality fixed by the general demands of the investing public. It follozvs as a necessary corollary that the greater the possible returns the greater the probable risk. The investments on which large returns are promised are usually those in which the r^sk is so great that large and experienced investors do not care to take the risk, and the securities have to be marketed by an appeal to the small and inexperienced investor. As a rule safe and sane enterprises do not hawk their stocks about and all stock pro- miscuously offered is probably dangerous. Opportunities to secure large returns from the organization of great business enterprises, the development of natural resources, or of really valuable inventions, are seldom offered to small Investors. Such enterprises if safe, sure, and conservative, are almost always financed by a few large interests that are conversant with their value, and the small investor is offered only the securities which will net moderate returns more or less commensurate with the apparent risks involved or questionable investments the hazards of which are so great that they do not appeal to the experienced financiers. The value of any security depends primarily : 1. On the management; that is, the honesty, reliability, and experience of the parties in charge of the business admin- istration. 2. On the real value of the property (if any) on which the security is based. To those unacquainted with business methods, any security offered should be regarded as of doubful value : 1. If if is offered as a special favor. 2. If it is in the promotion stage. 3. If it is a mining or oil stock in course of flotation. 38 Success in Engineering 4. If it depends upon some new invention. 5. If it is in a large degree speculative. 6. If it is slated to be marked up on a certain date. 7. If it must be bought without sufficient time for investi- gation. 8. If it is declared certain to return undue profits. 9. If it has only unknown interests connected with it. 10.

If urged by repeated letter, circulars, etc., that it must be brought now or great profits will be lost. 18. If it is bunched with other offerings at a reduced figure. 19. If those selling a security fail to give the names of the officers and directors of the offering concern. 20.

Business, Finance and Engineering. — At the present time the engi- neer is frequently called upon not only to design and construct works but also to pass upon all features of works and projects including their business and financial relations. In most cases the financial and business factors are primarily more important than those of design and construction for a project that is not a financial success can not be regarded as a success although it may be successful from a structural standpoint. The financial problems which commonly must be considered by the engineer may be classed as: i .Business, Finance and Engineering 39 1. Economic Selection or the determination of the most eco- nomical design for accomplishing a given purpose. This is the question in economics most common in engineering practice. It includes the selection of the best type of materials for construction to meet certain demands, the best class of machinery to furnish certain service, and the best design to fulfill certain requirements. It enters into every phase of design. 2. Economic Management or the determination of the best methods of management and operation of factories, utilities, and projects and the methods by which a new business can best be managed or an old business can be improved, operation costs re- duced, and profits increased. 3. Economic Expediency or the advisability of a project when the best design is considered for the purpose it is desired to fulfill. This includes such questions as the advisability of the construction of a railroad or interurban line between certain places ; of the con- struction of hydro electric plants or power stations to serve certain districts ; of the development of drainage or irrigation or other projects and of the purchase or rehabilitation of properties or works already constructed. 4. Economic Worth or the determination of the physical, struc- tural, and commercial worth or value of a plant or project for the uses and purposes it is intended to fulfill. This includes the ques- tion of valuation and appraisal; the question of the present value of public utilities for purchase and rate making; and of private enterprises and manufacturing plants for financial investments. For the greatest professional success, the engineer must prop- erly train himself to solve these problems successfully. The knowl- edge, judgment, and experience required for such solutions are much more complex, intricate, and extended than are required in engineering design or construction. § 14. Professional Improvement. — In order to grow and to de- velop, the engineer must acquaint himself with the ideas and activities of others who are working in his own field. It is therefore essential that the young engineer should mingle with his fellows and compare his ideas with those of others in professional lines. He should early associate himself with those technical societies before which those prob- lems of engineering in which he is particularly or generally interested, are discussed and he should at least listen to or read the papers and discussions of others both in the society proceedings and the technical papers in order that he may gain a proper idea of current engineering 40 Success in Engineering and practice and judge and appreciate the limitations of his own abiUty. When he can contribute to the information by paper or discussion it will be distinctly to his own advantage to do so for in so doing he will strengthen his own knowledge and abilities and subject his work and conclusions to the criticism of others and frequently thereby correct his misconception. For this purpose the minor state and local engineering societies are of great advantage, for before such societies matters of local and personal interest can be discussed to advantage. A good paper properly prepared which describes the development and successful completion of new work and the experiences resulting therefrom, or coordinates the experience gathered from extensive ob- servation and study, not only improves and intensifies his own concep- tion of the problem, but establishes a record of his work, extends his acquaintance, and is of such direct professional benefit to the writer as the importance of the matter and the general excellence of its treat- ment may determine. In the preparation of such papers due acknowl- edgment should be made of personal indebtedness to others for data re- ceived, information furnished or the use of illustrations and sugges- tions in the preparation of papers and technical articles. Piracy of ideas or plagiarism should be studiously avoided, and a kindly consid- eration of the rights and feelings of others and a proper recognition of their aid and courtesy are highly desirable. The young engineer should constantly seek information on the various phases of engineering work with which he comes in contact, for otherwise the opportunity for acquiring special information and special experience with its consequent advantages will pass unnoticed. Opportunity seldom announces its advent with trumpets, and when so announced is mostly likely to prove a pitfall instead. Opportunities to acquire specialized information that is greatly needed in the engineer- ing and business world lie on every hand and await the mind that can appreciate, develop and apply them to practical needs. Those that are the most obvious and easily developed commonly offer the greatest com- petition and the lesser emoluments. Those that are the most obscure and difficult frequently return the greatest rewards for the intelligence and devotion which their successful development demands. To see the opportunity, to develop it systematicailly, to apply it in- telligently, and to apprehend from its conquest a well earned success, requires keen foresight, an appreciation of the present and future trend of events, and both general and special knowledge and experience. There is scarcely a line of professional work in which radical improve- ments are not both desirable and possible. New conditions are con- stantly developing that old practice is inadequate to satisfy. New lines Professional Improvement 41 and new specialties are in constant demand. The man who can see these needs before they are fully recognized and offer an effective method for their satisfactory fulfillment, will usually command a suit- able reward. The successful solution of a problem or the completion of a well considered and commendable design for any engineering work should not limit the efforts of the engineer to improve his methods or designs when similar problems or similar works are under considera- tion. There are scarcely two problems of the same kind that can be solved to the greatest advantage in entirely the same manner. Every problem is surrounded by its individual conditions that differ to a greater or lesser extent and should modify any plan which is devised for its solution. There is scarcely a plant installed or a building or other structure erected but that the designer, if he gives it careful and thorough consideration, may not find methods of betterment if he were called again to solve the same problem. This being the case, it is evi- dent that each new problem should meet with a more intelligent solu- tion ; the new factors that are present should modify the original plans ; and the betterments which were possible in the first construction should here be adopted to advantage and probably still further elaborated. There is nothing stationary in nature, and the individual in his pro- fession or business relations is either advancing or deteriorating. As long as he can see ways and means by which his work can be improved, as long as he finds it necessary and desirable to study and investigate and to improve his knowledge, his ideals and their practical expression, so long is the engineer growing and improving and his value is increas- ing ; but as soon as he is satsified with his work and believes no further improvement to be possible, his progress has ceased and, at least in comparison with the normal advancement in professional work, he is losing ground, and unless he acquires an entirely different attitude, his usefulness will soon be a thing of the past.

THE ENGINEER AT WORK § 15. Purposes and Results of Technical Training. — It is not the aim of professional schools to turn out professional men. The Hmited time spent in the technical school and the object sought do not warrant such a purpose. The object of professional training of tech- nical men has already been considered (see Sec. 3) and the necessity of developing judgment, accuracy and speed by the practical applica- tion of such training to actual work has also been discussed (see Sec. 9). It is evident to all practicing engineers and architects that the sub- jects studied in the schools can become of practical value to the pro- fessional man only through their actual application under many condi- tions and in many places. Practical knowledge may be developed to a considerable extent in a trade school for its field is limited to narrow lines, but in a professional school the field is so broad that the oppor- tunities for such development are small and real professional knowledge must be gained or at least improved largely by practical experience. If the student has become thoroughly interested in the profession which he has chosen, if he has acquired the ability to apply himself to work and study, if he has attained a good conception of the manner in which and the source from which professional information can be obtained, and has gained at least limited facilities in the use of those elementary features of practice on which his early employment will probably de- pend he has done all that can reasonably be expected in a graduate of a technical school. He has not become a professional man, but he has acquired a capacity which when properly exercised will assure him the professional standing which his abilities and opportunities afford when his experience and practice have made the theoretical knowledge of the school the actual individual knowledge of the man. In practical life, the facts of importance in a material way are the ends, not the means. Except as an aid in estimating possible knowledge and ability, the mat- ter of education and experience is of no material importance to the em- ployer. The question is : Can the man properly fill the position for which he applies or for which he is considered? Both education and experience are valueless in practical life unless they can be intelligently applied to useful ends. 44 The Engineer at Work There can be no exact measure of the factors that determine indi- viduaili usefulness in life. Every position has certain definite require- ments and these must be fulfilled. For calculations a man must have sufficient mathematical knowledge for his purpose. He who has no such knowledge is useless for such work. If the work requires the ex- ercise of judgment, mathematical knowledge alone is useless; and if fiduciary relations are also involved, character may also become of equal or greater importance. The characteristics discussed in Sec. 9 and their relative percentages of importance, seems fairly to repre- sent a somewhat definite ideal of professional men as to the factors es- sential to engineering success. The main ends of present day pro- fessional education emphasize the last two, although most educators recognize the relatively greater importance of the first four which are impressed on the technical student only incidentaiUy if at all with the various subjects taught. To what extent they can and should be im- pressed on the student is an open question. That these factors must be developed to the extent necessary in every particular case cannot be questioned. Few technical graduates are of much immediate value either in the office, the factory or the field, and they can make themselves of value only by the acquisition of character, judgment, efficiency, executive ability and the practical ability to apply their technical: knowledge to the extent necessary or their individual needs by actual experience in such technical work. The young graduate is usually incompetent except in minor posi- tions ; he commonly overrates his capacity and seldom recognizes his own inexperience and incompetency to fill positions of responsibility and trust. His education gives him the opportunity to secure subor- dinate employment and to acquire and demonstrate his abillity to fill satisfactorily higher positions which may be open to him. Intelligent observation, close application and hard study will fit him for higher positions and better things. He frequently fails to recognize the chances for betterment afforded him by the minor positions which he first secures, and his failure to advance is often largely due to his dis- satisfaction in his subordinate position and his personal failure to take advantage of the immediate opportunities offered to acquire practical knowledge and experience and thereby make himself available for ad- vancement. § i6. The Man and the Job. — To secure the most economical and satisfactory results, both for the job and for the man, it is desir- able that the man best fitted for each place should secure the position, The Man and the Job 45 whatever its importance. This would accompHsh the best that the proper exercise of the necessary abihty can secure and would permit the development of the individual ability to its maximum. In practical life such desirable results can only be approximated. Positions and men are often widely separated and consequently the man and the very best position for which he is suited may seldom come in contact. The problem on the one hand is to secure the best available man for a given position, and on the other hand for a man to secure a position in which his services will be satisfactory and which will give him the greatest returns not only in income but in personal satisfac- tion. As engineering positions are often widely scattered and often far from the centers of technical education, some methods of intercom- munication become necessary. A young man through his own connec- tions or acquaintances is frequently in touch with possible openings for technical work. In prosperous years there are so many applications to technical institutions for men to fill subordinate positions that the first position is readily secured, and a letter of recommendation when a vacancy occurs is often all that is necessary. In dull years the diffi- culty of securing an immediate opportunity for technical work is much greater for then new men are not in great demand. Civil service ex- aminations for national, state and municipal positions are sometimes open to the technical graduate. Letters of inquiry to companies and individuals in charge of engineering work will occasionally lead to op- portunities for employment, but as a general rule an employer desires either a personal recommendation from some one with whom he is acquainted either personally or by reputation, or a personal interview with the man who seeks employment. Letters of application or personal interviews, if apparently promis- ing, should be followed up within a few weeks, otherwise it will usually be assumed that a position has been secured and the application will be ignored. Letters of recommendation from teachers or former employers will often be of advantage, the former for securing opportunities for minor positions and the latter for more advanced work. Usually only copies of such letters should be sent as in many cases they will not be returned. For higher positions, personal references are often of greater value than letters of recommendation. The letter of recom- mendation is always favorable or it would not be presented. The letter written direct is likely to give a more correct and complete statement of the character and ability of the applicant. Where teachers or former employers are to be used as references, where they have not been 46 The Engineer at Work familiar with the engineer's work for some years, it is desirable to communicate with them, giving a resume of the activities on which the individual has been employed in the intervening time. A reference to a teacher or employer who has heard nothing of the applicant for five or ten years is not apt to be satisfactory. It is only proper courtesy to secure the personal consent of those to whom it is desired to refer, but if acquaintance warrants reference without such permission, the fact of such reference should be immediate^.y con- veyed to the party to whom reference is rdade. The various engineering societies make some attempt to bring into communication employees desiring work and employers needing help. This useful function of the technical society should be much further developed. Advertising for a position may prove of value where a man has acquired considerable special experience or developed in some special line. In such cases an advertisement may attract the attention of those who may be in need of the particular service in question. Employment agencies also ofifer a means of communication between employees and employers. When these are considered, their standing should be in- vestigated and they should be used with caution. For higher positions, favorable and wide acquaintance, a clean record and a good personal and professional reputation based on satis- factory service, experience and ability, are the principal factors. These must be acquired by suitable effort and the more widely they become known the better capital they become for the future. § 17. Influence. — The value of the influence of family, friends and acquaintances should not be underestimated, but it is equally im- portant that it should not be overrated. Influence frequently brings opportunity, but character, energy and ability are essential to success- ft^lly improve the opportunities when offered. The position that is not only acquired by influence but is retained by pull instead of by push is a serious detriment to the individual unfortunate enough to employ such means. The retention of a position by influence dwarfs char- acter, undermines ability, weakens conscience and destroys initiative and personal reputation. The cultivation of friends and acquaintances, both social and pro- fessional, may result in valuable assistance when needed, if the char- acter, ability and experience of the individual warrant its exercise. The seeking of friends for a purely utilitarian purpose should not be con- sidered, for such aim will surely defeat itself. True friendship must be based on reciprocal esteem, respect and personal regard, founded on both character and ability. The First Job 47 § i8. The First Job. — As a first position an "easy job" is dis- astrous and leads to habits of indolence and inefficiency. The first work should be hard and exacting so that strenuous effort and con- centration may become a habit, for such habits develop men. A subordinate position with an organization of greater or less magnitude, either in the office, the factory or the field, is the first op- portunity for active service that usually comes to the young engineer. Such a position is seldom important in a relative sense but is most important to the individual for it is his first step in practical life, his first chance to "make good." How will he meet the demands of the situation? His future largely depends on his fitness to fulfill the re- quirements of the position. If he is interested in his work, is able, ac- curate, conscientious, dependable and loyal, he has begun the establish- ment of a reputation which will ultimately lead to success. These quali- ties will be recognized and his advancement is certain when opportunities occur. Such advancement will follow for it is demanded by the per- sonal interest of the employer, as men with marked characteristics such as described are not to be lost if their services are needed and can be retained on a reasonable basis. If he is interested only in his pay check, if he is careless in his work, heedless of instruction, inaccurate, inattentive, late in arriving and early in leaving his work, these facts will allso be noted, his prospects for advancement will be hopeless and he should seek other fields where, if he can eliminate these defects in his character, opportunities for betterment may occur. Many young men fail to appreciate the vital necessity of properly fulfilling subor- dinate functions or the real importance of such functions. Each unit is an essential part of the whole. The spire of the cathedral is conspicuous and is seen from afar, but every pile in the foundation is important, and the spire cannot stand without it. So the labor of the artisan, the mechanic and the subordinate is as necessary for the success of the structure as is that of the engineer, the architect or the builder and yet no individual is absolutely essential. If one falls out another will take his place, and the vacancy from the lowest to the highest is soon filled. Every man should recognize with both pride and humility his own importance and his own insignificance. If he does his duty to his best ability he is an essential feature in the endeavor of which he is a part. If he fails, he causes only a momentary disturbance, and his disap- pearance is only of brief interest except to himself and to those who are dependent upon him or especially interested in him. 48 The Engineer at Work § 19. Improving Opportunities. — Many young men after se- curing technical work soon become discontented with their prospects and feel that they have not obtained the position for which their educa- tion has fitted them. They fail to make a proper use of their oppor- tunities and soon seek a change in employment with the hope of find- ing the position for which they are best fitted. They fail to recognize the necessity of so shaping their personal efforts and improving their knowledge and training that their abilities will fit the conditions which opportunities offer. A desire for personal betterment is entirely com- mendable but it should be exercised so as not to embarrass those who have already given employment. If employment is accepted it entails a conscientious exercise of the ability of the employee, due diligence and loyalty, and a change should be made only when it can be made with- out undue embarrassment to the organization in which employment has already been secured. In most offices a notice of two weeks or more is given when an employee is to be laid off, unless he is discharged for palpable and reprehensible personal errors of commission or omission. The employee should give no less notice of his intention to leave the place he has accepted. When a man has accepted a position, it is a duty he owes both to himself and to his employer to do his best to fill the position in the most acceptable manner and to develop all there is in it and in him. Even if the line of service be regarded as temporary and he desires to finally concentrate his efforts in other lines, the self control and self restraint exercised to conquer a difficult or uninteresting subject, the abilities applied and the practical knowledge gained by conscientious study and effort will strengthen his character, increase his ability, en- large his experience and make him a broader, better and more useful man in whatever field of endeavor he may ultimately be employed. The man who withholds his best efforts with the hope of expend- ing them ultimately only in the field of his chosen work, so dwarfs himself as to render doubtful any great success in any line. Probably not one-half of the men who graduate from technical courses ulti- mately enter the exact line of work which they have in mind in their college days. Conscientious and continuous effort in every posi- tion which they may occupy after leaving college will often develop their capabilities and make evident their fitness for other lines which in the long run prove more interesting, more remunerative and more satisfactory from every point of view. The satisfactory fulfillment of the first work begins to give the young man a real knowledge of his own needs, his aptitude and defects, His aptitude must be developed. I Improving Opportunities 49 his errors eliminated. The establishment of a reputation for good or for ill is at once begun. Upon the degree of his success and opportuni- ttes at hand will depend his advancement. In general, he should retain his position until a promotion is secured or until he has developed him- self and this position to their reasonable limits. When there are no op- portunities within the organization, he should seek another and better position, leaving his work only after due notice. The young are nat- urally impatient at delay and expect rapid preferment. They often fail to see the opportunities which are the most obvious and make early changes in employment, to their ultimate disadvantage. A new posi- tion should offer some immediate and important advantage or some tangible opportunities, otherwise a change is undesirable, for the or- ganization in which a man has served has the best knowledge and will undoubtedly advance him when the opportunity offers because such ad- vancement is obviously to the logical advantage of all concerned. § 20. Selecting Employment. — While in many cases oppor- tunities for employment are so limited that little choice is afforded the young engineer in the selection of employment, yet in the long run he may exert considerable control over such selection if he makes careful preparation for his future work. It is evident in most cases that the future rather than the immediate present should be the objective of the young engineer. The line he desires to follow should be based so far as possible on his personal preference and on his personal fitness, apti- tudes and abilities. The greatest success will usually come with that line in the pursuit of which he experiences the greatest satisfaction and in which he can exercise to the greatest degree his native abilities and talents and his acquired knowledge and experience. That man is for- tunate who finds his professional or business life laid down on the lines he would most gladly follow and who in consequence is most thoroughly interested in the work he is called upon to do. It is evident therefore that immediate salary is of secondary consideration but that employ- ment should be sought in those lines and in those places where both opportunities occur and conditions give promise of ultimate preferment in the lines of the chosen work. Financial embarassment may oc- casionailly make a different course essential, and in such cases the em- ployee should endeavor to instill into his work the enthusiasm and in- terest required for his success. Continuous effort to this end will nor- mally create conditions of satisfaction quite equal to those which would result if he were able to pursue the line to which his early inclinations led. § 21. Salary. — The amount of salary to be received from a given position is naturally a matter of interest and frequently receives 50 The Engineer at Work greater consideration than its importance warrants. To the young technical graduate the matters of experience and opportunity are com- monly of much greater importance. If a young man is underpaid, he is apt to secure opportunities for a more extended experience than where his compensation is excessive, as for example in the apprentice's position in some of the large manufactories where opportunities are given to a technical graduate for a broad acquaintance with the ma- chinery designed and constructed through a great variety of work on the testing and erecting floors. If the salary received is more than should ordinarily be expected in a given position, it commonly means either that the work is tem- porary or that the man has found a niche into which he fits by unusual aptitude and in which he is likely to remain without the opportunity of acquiring a broader and more extended experience. If the salary is large, the services must be utilized to the greatest advantage in order to make them profitable, which commonly means that he will be kept on the one particular class of work in which he is especially proficient. Almost every position affords opportunities for experience and for study. Employment will not be furnished for long unless such em- ployment is profitable to those who furnish it. Advancement will not come until the individual has shown his dependability and his capacity for greater things ; and such capacity must be exhibited before and not after the advancement is secured. There are few cases where ability, capacity and dependability are not recognized, and advancement comes when opportunities offer with few exceptions and as a matter of course when these qualities are demonstrated. Few employers will permit em- ployees who have demonstrated their fitness for a position, to leave their service or advance strangers in preference. The employer for his own interests prefers those whose honesty, integrity and ability he knows, and he will seldom look elsewhere to fill an important position unless he is satisfied that such course is necessary in order to secure the desired re- sults. § 22. Change vs. Continuity of Service. — Formerly it was con- sidered desirable for the young engineer to remain in one position only long enough to thoroughly familiarize himself with the work, and then to seek other positions where his practical experience might be consid- erably extended. At the present time when hundreds of young engineers are gradu- ated from our technical schools each season, it would seem undesirable for any young man to drop a position which gave fair promise of ulti- mate betterment in order to accumulate a variety of experience which Continuity of Service 51 after all may be of little service in his professional career. It would seem by far the better way for the man to master thoroughly every detail of his business and to retain his position if it gives reasonable promise of ultimate betterment rather than to become a wanderer from job to job with each position more difficult to secure as his age in- creases. Each man must however be the architect of his own fate. The man who through lack of initiative accepts a permanent subordinate po- sition when he might better himself by a proper change, is perhaps more or less unfortunate ; but if he accepts his lot with contentment and is able to satisfy reasonably well his needs and ideals, he must be regarded as reasonably successful ; while the ambitious man who fre- quently changes from place to place in the hopes of uUimately finding the position which best fits his peculiar tastes, aptitudes and personal ambitions, may remain unsatisfied and unsettled through life and in his advanced years be forced into unsatisfactory employment because the position he desires is filled by a younger man. Constant change in po- sition is often evidence of weakness in ability, temperament or charac- ter, though it sometimes is the result of lack of opportunity. During seasons of hard times or panic, when public work has largely ceased and no new investments and establishments are prac- ticable in the railroad and public utilities fields or in the mines and fac- tories, thousands of engineers lose their positions and find nothing in their professional line open for them at any price. They must en- deavor to find work in other fields which are perhaps similarly inactive, or await the resumption of business in better times. During such times, the advantage of having secured a position in a permanent organiza- tion, and having made the value of the services almost indispensable, is evident. § 23. The Relative Values o£ Various Classes of Employment. The relative values to the technical man of various classes of profes- sional employment must depend largely on the personal inclination and point of view. Architecture and many special forms of technical work are definite and after selection require no further comment. The en- gineering student who has not specialized may perhaps be benefited by a brief discussion of various lines of work in which opportunities for employment may occur. When the education of the student is general, the opportunities for employment are co-extensive with the whole engineering field. Out- side of the field which permits the application of personal aptitude, it makes little difference in what line of employment he begins, as all work 52 The Engineer at Work furnishes desirable experience. At the end of a series of years he has acquired knowledge and skill in certain definite work, and his chances for the profitable sale of his services are limited to a much narrower field. IMany engineering students have the wrong point of view in re- gard to the best opportunities for ultimate professional advancement. It has already been noted (see Sec. 12) that the field engineer is the ideal of most engineering students. It is worthy of note that the office almost without exception controls the field and that many men who have had long experience in the field fail of further advancement for the lack of knowledge and experience in office work. Experience in field work usually leads to parallel advancement. The time keeper, the store keeper, and the inspector become the foreman, the superin- tendent and the resident engineer. Good office work leads to advance- ment in the office. The able draftsman becomes the designer, the as- sistant engineer, and with experience, the chief. Surveying and field work in many countries can be done to advantage only at certain periods. Drafting usually ofifers more steady employment and has the advantage of placing the employee near the responsible head of the organization. Dififerent classes of employment offer varying advantages. Con- struction work is often temporary unless with a permanent organiza- tion. Unfortunately, many engineering positions have no future. The work is more or less temporary and in dull times and seasons the em- ployment ceases and the employee must look for new fields. In this way he may, and frequently does, pass from one job to another, hold- ing each position until the work is accomplished, and never becoming settled or a permanent part of any engineering organization. Engineering employment may often lead to business opportunities. The young man with capacity who, after he has acquired the experi- ence which can be obtained in engineering positions connected with great industries, has the foresight and the energy to drop out of line of promotion which may be of only limited opportunities, and to take a position through which he will acquire a knowledge of operation, main- tenance and general business management, will frequently be rewarded by placing himself in line for greater business opportunities than are possible if he confines his efforts to the purely engineering phases of the work. Public service corporations offer many opportunities for ultimate advancement. Employment with such corporations may fre- quently result in permanent positions, and a qualified man will advance slowly but surely and may ultimately reach the highest position which such corporations have to offer. Classes of Employment 53 It is exceedingly desirable for the engineer to become at an early date a part of a permanent organization in a line which he will be con- tent to follow as a permanent life work. If a change into another line is desirable, it should be made at an early date ; delay greatly compli- cates the situation. If he withdraws from one line of work and enters another after considerable advancement has been attained, it must usually at the expense of salary, for he will not have the value in any other line without acquired experience. Foreign service is subject to the same disadvantage and should be regarded as a permanent life work, or abandoned early for work at home. Work in a foreign country involves a loss of touch with home conditions and professional acquaintance, and a change after some years abroad often results in the necessity of accepting a subordinate position at a greatly reduced salary. Employment in the government service has certain advantages and certain disadvantages. Compensation in the minor positions is usually equal to or greater than that which can be secured in private work, but the higher positions are not so well paid. On the other hand, those who reach advanced positions and display reasonable ability are assured of permanent positions. Instructional work in technical institutions is subject to the same comments. Such positions offer many opportuni- ties for development but they do not demand the constant exercise of energy and the continuous effort which are common to commercial work. If the individual lacks initiative and force, the opportunities for retaining the positions with a minimum of effort are conspicuous, and inclination in that direction will soon unfit the! individual for any important positions in commercial work. Whatever the work of the engineer may be his aim should be to do the work at hand properly to study and to improve. Advancement, where opportunities offer, will take care of itself if the young engineer by his acquisition of knowledge and skill is ready for promotion. § 24. Private Practice. — The great majority of engineering positions are salaried positions. Probably less than ten per cent, of the engineering profession is engaged in what is termed "private prac- tice." In such work the compensation is generally based on either a per diem basis or on a percentage of the cost of the work which is un- dertaken. In such practice the engineer usually furnishes all the as- sistants necessary for the making of the original surveys, the designs and plans, and for supervising the construction, and occasionally some of the larger organizations of this kind undertake the actual construc- tion of the work as well. 54 The Engineer at Work For success in private practice, at least on the larger and more im- portant works, extended experience on a great variety of work is re- quired, for in general the work of a private office cannot be devoted to a single specialty, although it is usually confined to certain definite re- lated lines. Occasionally a young man just out of college with only a few years of practice behind him attempts to enter private practice. If such work is confined to simple service such as drafting, surveying, etc., in which reasonable experience and adaptness have been attained, such a ven- ture is justifiable. When however the young engineer offers to the public inadequate experience, unsound judgment and insufficient skill for the proper performance of the work he desires to undertake, his attempt is unjustifiable and immoral. The sale of skill and knowledge which are not possessed is fraud, and although such a business may be conducted in such a manner as to escape the legal liabilities involved by misrepresentation, the moral sense is sacrificed with resulting perma- nent injury to the professional success of him who pursues such a course. Most attempts of this kind result in the failures which are rightly their due. If sufficient work is secured to pay expenses, it must usually be secured at a price too low for the class of services which should be rendered. Without broad experience proper services cannot be rendered, and on account of the low price received for his work, he is often unable to furnish even the best services of which he is cap- ab^.e. The results are unfortunate. He leaves behind him a record of work inadequately conceived and improperly done. He has mortgaged his future for an opportunity for an early professional preferment for which he was unprepared and he can never become more than of minor grade in his professional work. § 25. Duties to Subordinates. — While much has been said of the duties of the employee in the performance of his work, such duties are by na means reduced when he reaches a position where others are subject to his direction and supervision. As previously stated (Sec. 3), with professional advancement higher obligations are assumed and such obligations should be exercised not only toward the client or superior, but toward the subordinate as well. The engineer should advise and assist his subordinates and give them every reasonable encouragement and incentive to excel in their work. Criticism and reproof where nec- essary should be administered kindlv and with the idea of improvement, and praise and commendat'on shou'M be offered for initiative, skill and accuracy. Jealousy of subordinates and the consequent failure to ad- vise and assist them or to .s^ive them suitable credit for valuable ideas or suggestions is the sign of limited ability or an ungenerous disposition. Duties to Subordinates 55 The promotion of subordinates should be made on the basis of actual merit and not on the basis of capricious preference. If the superior is employing his subordinates for others, he is especially bound to con- sider intrinsic worth instead of personal preferment. In dealing with artisans and workmen a similar course of action is desirable. Nothing is gained and much is lost by harshness, conceit, and overbearing conduct. A feeling of injustice and resentment is seriously detrimental to the esprit de corps of any engineering force in the office or the field, and every force is bound to exhibit to a consider- able degree the spirit displayed by those in authority. § 26. Duties to Clients. — The relations of the engineer to his clients are fiduciary in nature and therefore involve, both legally and morally, obligations which must be exercised even at the sacrifice of personal interests. The client must place his trust in the personal hon- esty, business integrity and professional ability of his engineer. Fre- quently this trust involves not on'y large construction cost but the suc- cessful outcome of an endeavor of great importance. The client is frequently entirely ignorant of the technical features of the work and is only interested in it as a business venture. He may know nothing of the hazards or contingencies involved, and cannot judge of the relative values and costs of different methods of development, different ma- terials and machines or the effects of the same on the ultimate aims to be attained. The engineer must stand between his client and all ad- verse interests. The desire of the contractor to cheapen the w^ork of construction, the desire of the manufacturer to secure the sale of more or less suitable machinery, the desire of the promoter to finance more or less questionable ventures, and many other interests must be care- fully scrutinized, fairly considered, and properly adjusted. To be a suitable adviser for such responsible positions, the en- gineer's loyalty must be beyond question ; his only interest must be that of his client in every right and proper way. "No man can serve two masters for either he will hate the one and love the other, or else he will hold to the one and despise the other." (Matt. 6 '.24). This prin- ciple has been recognized as essential by the best men of every as^e and nation and in every business and profession. If the engineer has ad- verse interests of any kind, no matter how innocent they may appear, they will bias his judgment and he will do less than his duty. It is the insidious interest which has no apparent relation to the immediate work of engineering rather than the action that is frankly dishonest that is to be feared, for through such interests the first serious misstep may be taken. 56 The Engineer at Work It is not believed to be essential to discuss here the necessity of absolute honesty in such work ; personal interests with contractors, profits from the sale of materials, commissions from manufacturers, collusion with promoters, are not only obviously dishonorable and dis- honest, but so unquestionably immoral and against public policy that they render the individual amenable to the law. No one who respects his profession or who hopes for professional preferment could pos- sibly yield to such gross temptation. § 27. Consultation. — Commonly the man who is called upon to take charge of an important endeavor is one who has developed more or less special knowledge and ability in the principal field which with other phases constitutes the project. When a young engineer has been advanced to a position of responsibility and authority on a project of this nature he often feels that the importance of his position de- mands an exhibition of learning and ability that is often entirely be- yond his capacity. Nevertheless he is frequently impelled to attempt professional ventures quite beyond his experience rather than to ac- knowledge that even his abilities have their natural limitation. In this manner young men of undoubted ability frequently attempt pro- fessional work of a special nature for which they are in no way quali- fied, and risk the success of their employer's interests in a manner that is unjust and unwarranted. While such attempts are usually attended with more or less success, they usually fail to accomplish the results that might be attained by such expert service and wrongly deprive the client of the very best results. No man can be uniformly expert on all branches covered by many projects, and it is the sign of a narrow mind and limited ability for a man not to recognize his own limitations or to fail to call in expert aid when such aid can be used to advantage in his client's service. § 28. Duties to the Profession. — Every professional man is greatly indebted to his profession. His knowledge and usefulness have been greatly augmented by the labor and investigation, the successes and the failures of those who have gone before. The proceedings of technical societies, the articles in the technical press, the treatises on technical subjects and the opportunities of technical schools all afford the engineer occasion to enlarge his knowledge, expand his experience, increase his usefulness and make himself of greater value to himself and to the public. The high ideals and the dist'nguished ability that have been exercised by the men of the profession in the past bring to the professional man a consideration and standing which he could not oth- erwise enjoy. It is self-evident therefore that he who enjoys the mani- Duties to the Profession 57 fold benefits to be derived from the lives and labors of those who are his associates or have preceded him in his profession, is morally bound to maintain such ideals and conserve such respect by the exercise of his best judgment and best ability and by a high conception of personal re- sponsibility and of personal honor, and by a corresponding exercise of such ideals in his professional work. § 29. The Engineer in Business. — Engineering training af- fords a suitable foundation not only for professional work but also for various other occupations and vocations. It is a satisfactory training for the subordinate position of foremen, superintendents, salesmen and preliminary to entering the field of contracting for the construction of engineering work, for the manufacture of machinery, engineering ma- terials and supplies, and other occupations which have to do with or are intimately related to engineering work. Almost all that has been said of other activities applies to these and to any other lines of work in which the engineer may engage, whether directly or indirectly con- nected with technical affairs or in fields quite foreign to such matters. Honorable and conscientious service, intelligent application, consider- ate action and high ideals are the passports to high standing, public confidence and business preferment. § 30. The Engineer as a Citizen. — The failure of engineers as a class to take part in social and political activities is largely responsible for the lack of appreciation of the public at large for the engineering profession. The work of the engineer is often far from the public eye, in the office and in the field. He is often away from home and his mind is so concentrated on his work and on his duties that he is apt to avoid the public and is often almost a stranger in his own town except among his personal friends. No man should become so engrossed in his business or profession that he forgets or neglects his duties as a citizen. The engineer should lend his aid and support to every bene- ficial public movement and should be especially active in shaping public opinion and securing proper legislative action along those lines on which he is especially informed through his professional training and activities. In many matters in which the engineer is best informed the public needs advice and assistance. Agitators and politicians fre- quently encourage for their own ends popular prejudice for or against government action along lines with which the engineer is familiar or of which, through his training in the analysis of conditions and the deter- mination of facts, he is best fitted to judge. The public is largely ig- norant of the true principles underlying conservation, inland waterways, preparedness, public improvements, sanitation, municipal ownership, 58 The Engineer at Work and many other questions with which the engineer is or may easily be- come famiHar. With many of these subjects, unless there is an en- lightened pubHc opinion, the public through its legislators or members of congress, is liable to deal unwisely and unjustly. It is a duty of the engineer as a citizen to give the public the benefit of his training and practical experience in these various matters on which he is particularly able to render valuable service. Efficient and effective service in such matters will not only be of benefit to the public but will be of great value to the individual and en- hance the reputation of the profession in the minds of the people. § 31. Conduct of Professional Practice. — The conduct of the engineer or architect in the practice of his profession should be gov- erned by a strict regard for the rights of others and an appreciation of the duties, he, as a professional man, owes to all with whom he has busi- ness relations. The American Institute of Architects offers certain advice relative to the principles of professional practice, which it recommends to its members.^ In most respects this advice is directly applicable to engineering practice as well. While these principles may not seem directly applicable to the conduct of the young engineer in minor professional positions, they contain the basic principles on which all such conduct should rest, and if read in connection with the codes of ethics which follow, will furnish the necessary information for the proper course of individual action in most cases. The American Institute of Architects, seeking to maintain a high standard of practice and conduct on the part of its members as a safeguard of the important financial, technical and esthetic inter- ests entrusted to them, offers the for.owing advice relative to pro- fessional practice : The profession of architecture calls for men of the highest integrity, business capacity and artistic ability. The architect is entrusted with finan- cial undertakings in which his honesty of purpose must be above suspicion; he acts as professional adviser to his client and his advice must be abso- lutely disinterested; he is charged with the exercise of judicial functions as between client and contractors and must act with entire impartiality; he has moral responsibilities to his professional associates and subordi nates; finally, he is engaged in a profession which carries with it grave responsibility to the public. These duties and responsibilities cannot be prop- erly discharged unless his motives, conduct and ability are such as to com- mand respect and confidence. No set of rules can be framed which will particularize all the duties of the architect in his various relations to his clients, to contractors, to his 1 Reprinted from the "Quarterly Bulletin" of the American Institute of Architects. Adopted by the Institute at the Washington convention, Dec. 14-16, 1909. Conduct of Professional Practice 59 professional brethren, and to the public. The following principles should, however, govern the conduct of members of the profession and should serve as a guide in circumstances other than those enumerated: 1. ArchitecVs Status. — The architect's relation to his client is primarily that of professional advisor; this relation continues throughout the entire course of his service. When, however, a contract has been executed between his client and a contractor by the terms of which the architect becomes the official interpreter of its conditions and the judge of its performance, an additional relation is created under which it is incumbent upon the architect to side neither with client nor contractor, but to use his powers under the contract to enforce its faithful performance by both parties. The fact that the architect's payment comes from the client does not invalidate his obli gation to act with impartiality to both parties. 2. Preliminary Drawings and Estimates. — The architect at the outset should impress upon the client the importance of sufficient time for the preparation of drawings and specifications. It is the duty of the architect to make or secure preliminary estimates when requested, but he should acquaint the client with their conditional character and inform him that complete and final figures can be had only from complete and final drawings and specifications. If an unconditional limit of cost be imposed before such drawings are made and estimated, the architect must be free to make such adjustments as seem to him necessary. Since the architect should assume no responsibility that may prevent him from giving his client disinterested advice, he should not, by bond or otherwise, guarantee any estimate or contract. 3. Superintendence and Expert Services. — On all work except the sim- plest, it is to the interest of the owner to employ a superintendent or clerk- of-the-works. In many engineering problems and in certain specialized esthetic problems, it is to his interest to have the services of special experts and the architect should so advise him. The experience and special knowl- edge of the architect make it to the advantage of the owner that these per- sons, although paid by the owner, should be selected by the architect under whose direction they are to work. 4. The Architect's Charges. — The Schedule of Charges of the American Institute of Architects is recognized as a proper minimum of payment. The locality or the nature of the work, the quality of services to be rendered, the skill of the practitioner or other circumstances frequently justify a higher charge than that indicated by the schedule. 5. Payment for Expert Service. — The architect when retained as an ex- pert, whether in connection with competitions or otherwise, should receive a compensation proportionate to the responsibility and difficulty of the service. No duty of the architect is more exacting than such service, and the honor of the profession is involved in it. Under no circumstances should experts knowingly name prices in competition with each other. 6. Selection of Bidders or Contractors. — The architect should advise the client in the selection of bidders and in the award of the contract. In ad- vising that none but trustworthy bidders be invited and that the award be made only to contractors who are reliable and competent, the architect pro- tects the interests of his client. 60 The Engineer at Work 7. Duties of the Contractor. — As the architect decides whether or not the intent of his plans and specifications is properly carried out, he should take special care to see that these drawings and specifications are complete and accurate, and he should never call upon the) contractor to make good oversights or errors in them nor attempt to shirk responsibility by indefinite clauses in the contract or specifications. 8. Engaging in the Building Trades. — The architect should not directly or indirectly engage in any of the building trades. If he has any financial interest in any building material or device, he should not specify or use it without the knowledge and approval of his client. 9. Accepting Commissions or Favors. — The architect should not receive any commission or any substantial service from a contractor or from any interested person other than his client. 10. Encouraging Good Workmanship. — The large powers with which the architect is invested should be used with judgment. While he must con- demn bad work, he should commend good work. Intelligent initiative on the part of craftsmen and workmen should be recognized and encouraged and the architect should make evident his appreciation of the dignity of the artisan's function. 11. Offering Services Grattiitiously, — The seeking out of a possible client and the offering to him of professional service on approval and without com- pensation, unless warranted by personal or previous business relations, tends to lower the dignity and standing of the profession and is to be condemned. 12. On Advertising. — Publicity of the standards, aims and progress of the profession, both in general and as exemplified by individual achieve- ment, is essential. Advertising of the individual, meaning self-laudatory publicity procured by the person advertised or with his consent, tends to defeat its own ends as to the individual as well as to lower the dignity of the profession, and is to be deplored. 13. On Signing Buildings and Use of Titles. — ^The, unobtrusive signa- ture of buildings after completion is desirable. The placing of the architect's name on a building during construction serves a legitimate purpose for public information, but is to be deplored if done obtrusively for individual publicity. The use of initials designating membership in the Institute is desir- able in all professional relationships, in order to promote a general under- standing of the Institute and its standard through a knowledge of its niemlbers and their professional activities. 14. On Competitions. — An architect should not take part in a com- petition as a competitor or juror unless the competition is to be conducted according to the best practice and usage of the profession, as evidenced by its having received the approval of the Institute, nor should he con- tinue to act as professional adviser after it has been determined that the program cannot be so drawn as to receive such approval. When an archi- tect has been authorized to submit sketches for a given project, no other architect should submit sketches for it until the owner has taken definite action on the first sketches, since, as far as the second architect is con- cerned, a competition is thus established. Except as an authorized com- petitor, an architect may not attempt to secure work for which a com- petition has been instituted. He may not attempt to influence the award Conduct of Professional Practice 61 in a competition in which he has submitted drawings. He may not accept the commission to do the work for which a competition has been instituted if he has acted in an advisory capacity either in drawing the program or in making the award. 15. Injuring Others. — An architect should not falsely or maliciously in- jure directly or indirectly, the professional reputation, prospects or business of a fellow architect. 16. Undertaking the Work of Others. — An architect should not under- take a commission while the claim for compensation or damages, or both, of an architect previously employed and whose employment has been ter- minated remains unsatisfied, unless such claim has been referred to arbi- tration or issue has been joined at law; or unless the architect previously employed neglects to press his claim legally; nor should he attempt to sup- plant a fellow architect after definite steps have been taken toward his employment. 17. Duties to Students and Draftsmen. — The architect should advise and assist those who intend making architecture their career. If the beginner must get his training solely in the office of an architect, the latter should assist him to the best of his ability by instruction and advice. An architect should urge his draftsmen to avail themselves of educational opportunities. He should, as far as practicable, give encouragement to all worthy agencies and institutions for architectural education. While a thorough technical preparation is essential for the practice of architecture, architects cannot possibly insist too strongly that it should rest upon a broad foundation of general culture. 18. Duties to the Public and to Building Authorities. — An architect should be mindful of the public welfare and should participate in those move- ments for public betterment in which his special training and experience qualify him to act. He should not, even under his client's instructions, en- gage in or encourage any practices contrary to law or hostile to the public interest; for as he is not obliged to accept a given piece of work, he cannot, by urging that he has but followed his client's instructions, escape the con- demnation attaching to his acts. An architect should support all public offi- cials who have charge of building in the rightful performance of their legal duties. He should carefully comply with all building laws and regulations, and if any such appear to him unwise or unfair, he should endeavor to have them altered. 19. Professional Qualifications. — The public has the right to expect that he who bears the title of architect has the knowledge and ability needed for the proper invention, illustration and supervision of all building operations which he may undertake. Such qualifications alone justify the assumption of the title of architect. LITERATURE Industrial Leadership, by H. L. Gault. Yale University Press, New Haven. Trade Morals, by E. D. Page.

CHAPTER IV PERSONAL AND ETHICAL RELATIONS § 32. Limitations of Positive Law. — The necessity of a guide to human conduct has been recognized in every age and by every peopiC. With primitive people, might made right, and force was the basis of the settlement of disputes until this became recognized as an unsatis- factory and a needlessly expensive method for the adjustment of social relations. Even today in international relations, the law of might is frequently exercised and such exercise is a sad commentary on our present so-called civilization. The necessity for satisfactory, estab- lished social and business relations resulted in the establishment of positive law which, while it has grown, developed and improved, still leaves much to be desired. While positive law fixes certain social and business obligations be- tween individuals, and provides a method by which further obligations can be established by agreement, yet even where an attempt is made in a contract to specify in the greatest detail the limitations of such obli- gations, there are many points of contact in both social and business intercourse over which no successful legal control can be established. Positive law is an attempt to crystalize the ideas and convictions of the citizens of a country as to those obligations and that conduct which, established by custom, usage and experience, seem to afford the greatest degree of justice and equity under average conditions in the relationship of man to man. Such laws fall so far short of accom- plishing their object that courts of equity have been established to miti- gate and supplement the law in cases where strict legal relief is im- practicable. Laws were originally enacted with the object of protecting par- ticularly the established rights of the ruling class, and were modified to benefit the more unfortunate only as revolution or change in the moral and ethical view of the people required. Even today undue weight is frequently given to vested and property right, to the detri- ment of the unfortunate. While the observance of legal rights is highly important, still a society in which none but legal rights are recognized would constitute a most unhappy community. \ 64 Personal and Ethical Relations § 33. Ethics. — While the law defines the privileges of the individ- ual in the larger matters of life, it does not always assure equity and justice even in those matters, and is a guide to a limited extent only in the every day relations of man to man. The individual conduct in those manifold intimate relations which are not governed by legal en- actments has more to do with character and success than the observa- tion of mere legal requirements. It is not sufficient that the law be ob- served, for a man may live strictly within the law and be most unde- sirable as a citizen, friend or neighbor. To the honorable business or professional man, the question of a legal right in regard to a course of conduct is of secondary importance to the ethical right, and he will not exercise legal rights which are not also morally sound. As has already been pointed out, the law only ap- proximates justice and equity, and frequently in its application falls far short of the object. Then again, the exercise of a legal right some- times involves legal action, which in turn requires an expenditure of time and money often unwarranted by the results which may be at- tained ; so the legal right, while equitable, may not be enforced on ac- count of the trouble involved. Unfortunately there are men who are willing to take advantage of all laws favorable to themselves even though entirely unjust, and to take advantage of the unwillingness of others to sustain their rights in court and to trespass on those legal rights so far as can safely be done. Moral and ethical principles undoubtedly began to develop prior to the establishments of even the most primitive forms of positive law and have grown and developed concomitant with the development of the law. Mankind has long recognized the imperfections in positive law and has attempted to control through religion and moral associa- tions and societies and through established public opinion, those human actions which need control for the general and individual good but which positive law has failed to effect. In general every country has a certain moral or ethical standard which may be regarded as established by custom and common approval. Such standards are more or less im- perfect. True ethical principles are not a matter of custom but are well understood and have been recognized by the best men in all ages and in all walks of life. The ethical code established by custom changes with the development of society and can reach perfection only when society develops- morally far beyond its present condition. The net practical results of the ethical development of any nation must be adjudged by the existing conditions. Social conditions which will permit of so much crime and poverty as now exist in every coun- Ethics 65 try, are not ideal and these conditions which now obtain are undoubt- edly largely due to the unethical legal and social organization of so- ciety and to ignorance of how best to accomplish the desired results, and unwillingness to waive personal advantage in favor of moral obli- gations. In every society there are individuals who fail to recognize, or at least to exercise, even those ethical and moral obligations which are regarded as well founded by the society in which they live, and who undoubtedly accomplish certain desired results and derive certain profits and apparent advantages by such disregard. Humanity is weak, and few individuals who have lived active lives in constant contact with their fellow men, have always observed those ethical obligations which they in their conscience recognize as morally just and equitable. § 34. Formation of Individual Principles. — It is essential that every individual who is to take part in business or professional life should adopt or form individual principles of action for guidance in his relations to others with whom he must necessarily come in contact, for without such principles he will not be able to act promptly and he will be uncertain in his relation to men, and often be led into embar- rassing positions with possible loss of his self-respect and reputation. The principles to be adopted should be sound and, at least until sub- stantiated by personal experience, should be based on the consensus o5 opinion of those men to whom the individual looks with confidence and respect. Without such principles mistakes are certain and the individual may be led into a course of action which will seriously affect his future. The first step in unethical conduct is often inadvertent and is made through ignorance. Conditions often render further departure ap- parently expedient or necessary. The moral ideals become blunted, and ethical principles are ignored because of the unethical attitude of asso- ciates and competitors, with the thought or expression that "If we go to Rome we must do as the Romans," or *Tf we do not do this some one else will." On such false ideas the downward path begins ; and ends where? There can be no question that as a basis of a successful life, and entirely apart from moral and religious ideals, "Honesty is the best policy." Even those who have occasion to use the services of a dishon- est person cast him aside when his immediate use is over, well knowing that he who will sell himself once may do so a second time, and to the detriment of his first employer. The material profit which may tem- porarily accrue from unethical conduct so dwarfs the intellects of those 66 Personal and Ethical Relations who yield to its temptation that it is bound to lead to moral and pro- fessional ruin. It is therefore essential in business and in professional life that the individual be honest, preferably from an ethical and moral stand- point, but if not from this point of view, then certainly from the stand- point of policy. At the best, life is brief, and true usefulness and happiness should be its aim, and while the engineer or other professional or business man may acquire comparatively little wealth, he can and should own himself, and his dearest possession should be a spotless reputation. Honesty and integrity lead to dependability. No amount of knowledge or work can take the place of these attributes. The man who can be depended upon is ever in demand, and if he has also acquired a high degree of knowledge and experience and an appetite for hard work, his true success, barring accidents, is assured. § 35. Specifications for a Man.* — "To respect my country, my profession, and myself. To be honest and fair with my fellow men as I expect them to be with me. To be a loyal citizen of the United States. To speak of it with praise and act always as a trustworthy custodian of its good name. To be a man whose name carries prestige with it wherever it goes. "To base my expectations of a reward on a solid foundation of service rendered. To be willing to pay the price of success in honest effort. To look upon my work as an opportunity to be seized with joy and to be made the most of, not as a painful drudgery to be reluctantly endured. "To remember that success lies within my own self and in my own brain, my own ambition and my own courage and determination. To expect difficulties and force my way through them. To turn hard experience into capital for future struggles. "To believe in my profession heart and soul. To carry an air of op- timism in the presence of those I meet. To dispel all temper with cheerful- ness, kill doubts with strong conviction, and reduce action" with an agree- able personality. "To make a study of my business. To know my profession in every detail. To mix brains with effort and system in my work. To find time to do every needful thing by not letting time find me doing nothing. To hoard days as a miser does dollars. To make every hour bring me dividends in increased knowledge and healthful recreation. To keep my future unen- cumbered with debts. To save as well as to earn. "To cut out expensive amusements until I can afford them. To steer clear of dissipation and guard my health of body and peace of mind as a most precious stock in trade. ♦Found among the papers of Thomas J. Van Alystyne, a .f.aduate of the Electrical Engineering department of Cornell University after his death which occurred on the job. — Cornell Civil Engineer, Vol. 23, p. 154. Code of Ethics 67 "Finally to take a good grip on the joys of life. To play the game like a man. To fight against nothing as hard as my own weakness and endeavor to give it strength. To be a gentleman and a Christian so I may be courteous to man, faithful to friends, and true to God." § 36. Code of Ethics. — Within the last ten years (1916) the dis- cussions of professional ethics have crystalized into the various codes of ethics which have been adopted by many technical societies. These codes do not presume to define all of the duties and obligations of the individual toward life, but express as far and as clearly as practicable the principles which should govern the professional relations of the en- gineer or architect to his client or employer, to other professional men, and to the public. While in general these codes are intended to apply to the conduct of the professional man in independent practice, they also afford valuable suggestions to the young engineer or architect as to his personal course of conduct. They are an expression of ideas which every man should thought- fully consider. These codes are however, rules which cover only a few features of professional conduct and entirely ignore the more important and more personal relations. They do not cover the field of ethics and a profes- sional man who follows them implicitly may depart in many ways from a proper ethical standard in his personal life. The man of experience and of high ideals who desires to live a life of usefulness and honor needs no formal code of ethics to guide his per- sonal or professional conduct. § 37. The Canons of Ethics of the American Institute of Archi- tects. — The following canons are adopted by the American Institute of Architects as a general guide, yet the enumeration of particular du- ties should not be construed as a denial of the existence of others equally important although not spec'fically mentioned. It should a^so be noted that the several sections indicate offenses of greatly varying degrees of gravity. It is unprofessional for an architect — 1. To engage directly or indirectly in any of the building trades. 2. To guarantee an estimate or contract by bond or otherwise. 3. To accept any commission or substantial service from a contractor or from any interested party other than the owner. 4. To take part in any competition which has not received the approval 01 the Institute or to continue to act as professional adviser after it has been determined that the program cannot be so drawn as to receive such approval. 5. To attempt in any way, except as a duly authorized competitor, to secure work for which a competition is in progress. 68 Personal and Ethical Relations 6. To attempt to influence, either directly or indirectly, the award of a competition in which he is a competitor. 7. To accept the commission to do the work for which a competition has been instituted if he has acted in an advisory capacity, either in drawing the program or in making the award. 8. To injure falsely or maliciously, directly or indirectly, the profes- sional reputation, prospects or business of a fellow architect. 9. To undertake a commission while the claim for compensation or damages, or both, of an architect previously emnloyed and whose employ- ment has been terminated remains unsatisfied, until such claim has been referred to arbitration or issue has been joined at law, or unless the archi- tect previously employed neglects to press his claim legally. 10. To attempt to supplant a fellow architect after definite steps have been taken toward his employment, e. g., by submitting sketches for a project for which another architect has been authorized to submit sketches. 11. To compete knowingly v^rith a fellow architect for employment on the basis of professional charges. § 38. Code of Professional Ethics of The American Institute of Consulting Engineers.^ — It shall be considered unprofessional and inconsistent with honorable and dignified bearing for any member of The American Institute of Consulting Engineers : 1. To act for his clients in professional matters otherwise than in a strictly fiduciary manner or to accept any other remuneration than his direct charges for services rendered his clients, except as provided in Clause 4. 2. To accept any trade commissions, discounts, allowances, or any indi- rect profit or consideration in connection with any work which he is engaged to design or to superintend, or in connection with any professional business which may be entrusted to him. 3. To neglect informing his clients of any business connections, interests or circumstances which may be deemed as influencing his judgment or the quality of his services to his clients. 4. To receive, directly, or indirectly, any royalty, gratuity, or commission on any patented or protected article or process used in work upon which he is retained by his clients, unless and until receipt of such royalty, gratuity or commission has been authorized in writing by his clients. 5. To offer commissions or otherwise improperly solicit professional work either directly or by an agent. 6. To attempt to injure falsely or maliciously, directly or indirectly, the professional reputation, prospects or business of a fellow engineer. 7. To accept employment by a client while the claim for compensation or damages, or both, of a fellow engineer previously employed by the same client and whose employment has been terminated, remains unsatisfied or until such claim has been referred to arbitration or issue has been joined at law or unless the engineer previously employed has neglected to press his claim legally. 8. To attempt to supplant a fellow engineer after definite steps have been taken toward his employment. 2 Authorized by the council, June 23, 1911. Code of Ethics 69 9. To compete with a fellow engineer for employment on the basis of professional charges by reducing his usual charges and attempting to under- bid after being informed of the charges named by his competitor. 10. To accept any engagement to review the work of a fellow engineer for the same client, except with the knowledge or consent of such engineer or unless the connection of such engineer with the work has been terminated. § 39- Code of Principles of Professional Conduct of The Amer- ican Institute of Electrical Engineers.^ — While the following prin- ciples express generally the engineer's relations to client, employer, the public, and the engineering fraternity, it is not presumed that they define all of the engineer's duties and obligations. (A) General Principles. 1. In all of his relations the engineer should be guided by the highest principles of honor. 2. It is the duty of the engineer to satisfy himself to the best of his ability that the enterprises with which he becomes identified are of legitimate character. If after becoming associated with an enterprise he finds it to be of questionable character, he should sever his connection with it as soon as practicable. (B) The Engineer's Relations to Client or Employer) 3. The engineer should consider the protection of a client's or em- ployer's interests his first professional obligation, and, therefore, should avoid every act contrary to this duty. If any other considerations, such as profes- sional obligations or restrictions, interfere with his meeting the legitimate expectation of a client or employer, the engineer should inform him of the situation. 4. An engineer cannot honorably accept compensation, financial or otherwise, from more than one interested party, without the consent of all parties. The engineer, whether consulting, designing, installing or operating, must not accept commissions, directly or indirectly, from parties dealing with his client or employer. 5. An engineer called upon to decide the use of inventions, apparatus, or anything in which he has a financial interest, should make his status in the matter clearly understood before engagement. 6. An engineer in independent practice may be employed by more than one party, when the interests of the several parties do not conflict; and it should be understood that he is not expected to devote his entire time to the work of one, but is free to carry out other engagements. A consulting engi- neer permanently retained by a party, should notify others of the affiliation before entering into relations with them, if, in his opinion, the interests might conflict. 7. An engineer should consider it his duty to make every effort to rem- edy dangerous defects in apparatus or structures or dangerous conditions of operation, and should bring these to the attention of his client or emnlove^. 3 Adopted by the board of directors, March 8, 1912. 70 Personal and Ethical Relations (C) Ownership of Engineering Records and Data. 8. It is desirable that an engineer undertaking for others work in con- nection with which he may make improvements, inventions, plans, designs, or other records, should enter into an agreement regarding their ownership. 9. If an engineer uses information which is not common knowledge or public property, but which he obtains from a client or employer, the results in the forms of plans, designs or other records, should not be regarded as his property, but the property of his client or employer. 10. If an engineer uses only his own knowledge, or information, which by prior publication, or otherwise, is public property and obtains no engi- neering data from a client or employer, except performance specifications or routine information, then in the absence of an agreement to the contrary the results in the form of inventions, plans, designs, or other records, should be regarded as the property of the engineer, and the client or employer should be entitled to their use only in the case for which the engineer was retained. 11. All work and results accomplished by the engineer in the form of inventions, plans, designs, or other records, that are outside of the field of engineering for which a client or employer has retained him, should be re- garded as the engineer's property unless there is an agreement to the contrary. 12. When an engineer or manufacturer builds apparatus from designs supplied to him by a customer, the designs remain the property of the cus- tomer and should not be duplicated by the engineer or manufacturer for others without express permission. When the engineer or manufacturer and a customer jointly work out designs and plans or develop inventions a clear understanding should be reached before the beginning of the work regard- ing the respective rights of ownership in any inventions, designs, or matters of similar character, that may result. 13. Any engineering data or information which an engineer obtains from his client or employer, or which he creates as a result of such infor- mation, must be considered confidential by the engineer; and while he is justified in using such data or information in his own practice as forming part of his professional experience, its publication without express permis- sion is improper. 14. Designs, data, records and notes made by an employee and referring exclusively to his employer's work, should be regarded as his employer's property. 15. A customer, in buying apparatus, does not acquire any right in its design but only the use of the apparatus purchased. A client does not ac- quire any right to the plans made by a consulting engineer except for the specific case for which they were made. (D) The Engineer's Relations to The Public. 16. The engineer should endeavor to assist the public to a fair and correct general understanding of engineering matters, to extend the general knowledge of engineering, and to discourage the appearance of untrue, un- fair or exaggerated statements on engineering subjects in the press or else- where, especially if those statements may lead to, or are made for the pur- pose of, inducing the public to participate in unworthy enterprises. Code of Ethics 71 17. Technical discussions and criticisms of engineering subjects should not be conducted in the public press, but before engineering societies, or in the technical press. 18. It is desirable that the first publication concerning inventions or other engineering advances should not be made through the public press, but before engineering societies or through technical publications. 19. It is unprofessional to give an opinion on a subject without being fully informed as to all the facts relating thereto and as to the purposes for which the information is asked. The opinion should contain a full state- ment of the conditions under which it applies. (E) The Engineer's Relations to The Engineering Fraternity. 20. The engineer should take an interest in and assist his fellow engi- neers by exchange of general information and experience, by instruction and similar aid, through the engineering societies or by other means. He should endeavor to protect all reputable engineers from misrepresentation. 21. The engineer should take care that credit for engineering work is attributed to those who, so far as his knowledge of the matter goes, are the real authors of such work. 22. An engineer in responsible charge of work should not permit non- technical persons to overrule his engineering judgments on purely engineer- ing grounds. (F) Amendments. Additions to, or modifications in, this Code may be made by the Board of Directors under the procedure applying to a by-law. § 40. Code of Ethics Suggested for The American Institute of Chemical Engineers (19 1 3). — Purpose of the Code: To define the rules of professional conduct and ethics for the members of the Institute. The Institute expects of its members: 1. That in all of their relations, they shall be guided by the highest principles of honor. 2. The upholding before the public at all times of the dignity of the chemical profession generally and the reputation of the Institute, protecting its members from misrepresentation. 3. Personal helpfulness and fraternity between its members and toward the profession generally. 4. The avoidance and discouragement of sensationalism, exaggeration and unwarranted statements. In making the first publication concerning in- ventions or other chemical advances, they should not be made through the public press, but through chemical societies and technical publications. 5. The refusal to undertake for compensation, work which he believes will be unprofitable to a client without first advising said client as to the improbability of successful results. 6. The upholding of the principle, that unreasonably low charges for pro- fessional work tends toward inferior and unreliable work, especially if such charges are set at a low figure for advertising purposes. 72 Personal and Ethical Relations 7. The refusal to lend their names to any questionable enterprise, 8. Conservatism in all estimates, reports, testimony, etc., especially in connection with the promotion of business enterprises. 9. That they shall not engage in any occupation which is obviously con- trary to law or public welfare. 10. When a chemical engineer undertalties for others work in connection with which he may make improvements, inventions, plans, designs or other records, he should enter into a written agreement with regard to their owner- ship; and when it is subsequently found that such an agreement does not cover a point at issue, the following rules shall apply: a. If a chemical engineer uses information which is not common knowl- edge or public property, but which he obtains from a client or employer, the results in the form of plans, designs or other records shall not be regarded as his property, but the property of his client or employer. b. If a chemical engineer uses only his own knowledge or information or data, which by prior publication or otherwise are public property, and obtains no chemical engineering data from a client or employer except per- formance specifications or routine information, then the results in the form in inventions, plans, designs or other records should be regarded as the property of the engineer and the client or employer should be entitled to their use only in the case for which the engineer was retained. c. All work and results accomplished by the chemical engineer in the form of inventions, plans, designs or other records, or outside of the field for which a client or employer has retained him, should be regarded as the chemical engineer's property. d. When a chemical engineer participates in the building of apparatus from designs supplied him by a client, the designs remain the property of the client and should not be duplicated by the designer or anyone representing him for others without express permission. e. Chemical engineering data or information which a chemical engineer obtains from his client or employer or which he creates as a result of such information must be considered confidential by the engineer; and while he is justified in using such data or information in his own practice as forming part of his professional experience, its publication without express permission is improper. f. Designs, data, records and notes made by an employee and referring to his employer's work, should be regarded as his employer's property. g. A client does not acquire any exclusive right to plans or apparatus made or constructed by a consulting chemical engineer except for the specific case for which they were made. 11. A chemical engineer cannot honorably accept compensation, financial or otherwise, from more than one interested party, without the consent of all parties; and whether consulting, designing, installing or operating, must not accept compensation directly or indirectly from parties dealing with his client or employer. When called upon to decide on the use of inventions, apparatus, pro- cesses, etc., in which he has a financial interest, he should make his status in the matter clearly understood before engagement. Code of Ethics 73 12. The chemical engineer should endeavor at all times to give credit for work to those who, so far as his knowledge goes, are the real authors of such work. 13. Undignified, sensational or misleading advertising should be dis- couraged. 14. Contracts made by chemical engineers should be subject to the Code of Ethics. For the administration of this Code of Ethics, a Committee on Ethics shall be appointed by the president holding office at the time of the adoption of this Code, to consist of five members; one appointed for five years, another for four years, another for three years, another for two years, another for one year, and thereafter, the president then holding office shall appoint one member annually to serve for five years and also fill such vacancies as may occur for the unexpired term. Three of these members shall be over forty- five years of age. The committee shall elect its own chairman. The Com- mittee on Ethics shall investigate all complaints submitted to them bearing upon the professional conduct of any member, and after a fair opportunity to be heard has been given to the member involved, shall report its findings to the Council, whose action shall be final. § 41. Code of Ethics Adopted by American Society of Civil Engineers, September 2, 1914. — It shall be considered unprofes- sional and inconsistent with honorable and dignified bearing for any member of the American Society of Civil Engineers : 1. To act for his clients in professional matters otherwise than as a faithful agent or trustee, or to accept any remuneration other than his stated charges for services rendered his clients. 2. To attempt to injure falsely or maliciously, directly or indirectly, the professional reputation, prospects, or business, of another engineer. 3. To attempt to supplant another engineer after definite steps have been taken toward his employment. 4. To compete with another engineer for employment on the basis of professional charges, by reducing his usual charges and in this manner at- tempting to underbid after being informed of the charges named by another. 5. To review the work of another engineer for the same client, except with the knowledge or consent of such engineer, or unless the connection of such engineer with the work has been terminated. 6. To advertise in self-laudatory language, or in any other manner derog- atory to the dignity of the profession. § 41-a. Code of Ethics Adopted by the American Society of Mechanical Engineers, May 24-27, 1920. 1. The mechanical engineer should be guided in all his relations by the highest principles of honor, of fidelity to his client, and of loyalty to his country. 2. His first duty is to serve the public with his specialized skill. In promoting the welfare of society as a who^e he advances his own interests, as well as those of the whole engineering profession. 3. He should consider the protection of his client's or employer's in- terests in professional matters his essential obligation, provided these in- terests do not conflict with the public welfare. 74 Personal and Ethical Relations 4. Ke shall refrain from associating himself or continuing to be as- sociated with any enterprise of questionable or illegitimate character. 5. He can honorably accept compensation, financial or otherwise, from only one interested party unless all parties have agreed to his recompense from other interested parties. 6.. He must inform his clients of any business connections, interests or circumstances, such as might influence his judgment or the quality of his services to his clients. 7. He must not receive, directly or indirectly, any royalty, gratuity or commission on any patented article or process used in the work upon which he is retained without the consent of his clients or employers. 8. He should satisfy himself before taking over the work of another consulting engineer that good and sufficient reasons exist for making change. 9. He must base all reports and expert testimony on facts or upon theories founded only on sound engineering principles and experience. 10. He must not regard as his own any information which is not com- mon knowledge or public property, but which he obtained confidentially from a client or while engaged as an employee. He is, however, justified in using such data or information in his own private practice as forming part of his professional experience. 11. He should do everything in his power to prevent sensational, ex- aggerated or unwarranted statements about engineering work being made through the public press. First descriptions of new inventions, processes, etc., for publication should be furnished only to the engineering societies or to the technical press. 12. He should not advertise in an undignified, sensational or mislead- ing manner, or offer commissions for professional work, or otherwise im- properly solicit it. 13. He should not compete knowingly with a fellow-engineer for em- ployment on the basis of professional charges or attempt to supplant a fellow-engineer after definite steps have been taken toward the other's em- ployment. 14. He should assist all fellow-engineers by exchange of general in- formation and valuable experience or by instruction through the engineer- i]ig societies, the schools of applied science, and the technical press. § 42. Questions in Ethics. — It is reasonably assumed that no one who is interested in the discussion of Ethics would deliberately fol- low courses of conduct which are clearly and undoubtedly wrong. In that no choice exists for any honorable man : he must pursue a certain many cases, a g^iven course of conduct is so obviously right or wrong line of conduct. Conduct may vary from such obvious conditions to those in which the questions of right and wrong are so indistinct that opin- ions may justly vary concerning the matter which, in extreme cases, may even become simply a matter of the individual con- science. Ethical rules as adopted by the various engineering so- cieties, while obvious in the abstract, are not always so obvious Questions in Ethics 75 in their application; and those applications which may be obvious to the man of affairs may not be apparent to the young man just entering practical life. Certain concrete conditions have therefore been stated, on some of which it seems desirable that the student should express his opinion, and the answers, after being examined, should be discussed and the ethics of the situation explained. By a thoughtful consideration of such questions and a full discussion of the same, the student will gain a more correct view of ethical principles than is possible by the study of a statement of the abstract principles. 1. A young engineer applied for a position that was to last six months, and secured the appointment in active competition with several others. After he had worked at the job for a month, he was offered an opportunity to greatly better his salary in another city. As he was financially irrespon- sible, he could easily leave without fear of legal action. Should he accept or decline the new offer, and why? 2. Assume that an engineer were an applicant for a certain position and were asked concerning the standing and qualifications of another engineer for the same position, concerning whom he has heard unfavorable reports. Should he give the information he possesses? 3. It is the ambition of many students of engineering to enter the field of general practice in what is often termed consulting engineering work. Is a young engineer who has had only one or two years' experience, war- ranted in offering his services to the public in such capacity? 4. A young engineer was employed for some years with an engineering firm and acquired considerable experience in their specialty. A party desiring some work done along that line, and hoping to secure the same at a low figure, proposed that the young engineer take up their work at odd times, inde- pendently of his employers who, as business was somewhat dull, could spare a part of his services. Was he justified in accepting such work, and why? 5. Is a practicing engineer, unfamiliar with the specialty, mentioned in question 4, justified in taking work in that line and trying to secure the young engineer mentioned therein during his spare time to do thework for him? 6. If an engineer is employed for a portion of his time by a state to examine and pass upon plans for work, on which he is supposed to be expert and over which the state has assumed a certain control, is he justified in seeking to practice his profession by undertaking to prepare plans and speci- fications for work along similar lines and within the same state? 7. In most state public service bureaus there is always considerable v/ork for the engineering department which is waiting for their consid- eration. Nevertheless some of the specialists are able to secure leave of absence to undertake personal work for private parties, thus delaying the regular work of the department. Is such action justifiable? 8. Should or should not an engineer who has prepared plans and speci- fications for a piece of work, bid on the same as a contractor, and why? 9. Plans and specifications were prepared by a firm of engineers for a water works system for a small city, and bids were invited. Another engi- neer, acting with a contractor, made plans for a cheaper system and attempted to secure the contract through their ability to do the work on the cheaper 76 Personal and Ethical Relations system at a less price than could be made by the other contractors on the official plans. Was the other engineer justified in his conduct, and why? 10. A company which had employed an engineer to prepare plans and specifications for certain work became dissatisfied and uncertain as to the safety of the plans he had proposed. In the absence of the engineer, and without advising him as to their intention, they called in another engineer, explaining in their letter that they desired him to check up the plans and advise them as to their safety and sufficiency. Should the second engineer accept or decline the service, and on what grounds? 11. A second company under similar circumstances, and with the con- sent of their engineer, called for similar services from another engineer, who accepted and found the works proposed would be perfectly safe but that while it was not obvious, yet he could easily show that a considerable sum of money could be saved and the plant made much more satisfactory by cer- tain minor changes. Such changes in plans would, however, probably reflect to some extent on the engineer of the work, and if the plans were allowed to stand, the possible saving or improvement would never be "known. Was it or was it not the duty of the consulting engineer to call the attention of the company to the defect, at the expense of his fellow engineer's reputation? 12. An investigation was made of a contemplated irrigation project and a favorable report was duly submitted by an irrigation engineer to a develop- ment company. Another engineer was called to make surveys, prepare plans and specifications and to supervise construction. After considerable prog- ress had been made in the detailed investigations, the engineer became con- vinced that the preliminary report was greatly in error and that the project could not be a success financially. His opinion was submitted to the devel- opment company, and they instructed him to keep his report confidential and to continue the work, with the intention of selling sufficient land to protect themselves from financial loss of the money already invested and perhaps be able to secure a profit. Was the engineer justified or not in continuing the work under such conditions, and why? 13. An engineer, having examined a water power project, reported to his clients that in his opinion the cost of development and other conditions would make the cost of the possible power output too great to make the project financially satisfactory. His opinion was accepted, and the matter was dropped by the client. Later, the same project was taken up by a power company, and the same engineer was asked to take charge of the development. What was his duty in the premises, and why? 14. In many promotional enterprises the success of a project will de- pend upon various factors whoch are often more or less uncertain. Some of these factors are original cost, cost of operation and the cost of financ- ing. Another very great uncertainty is the development expense or the interest and operating costs during the period when the plant is acquiring a business or the project is securing its customers, and many projects other- wise desirable become unprofitable on account of this serious expense. (a) If an engineer having had extensive experience along certain lines is satisfied that a project cannot be financially successful, while his clients not thoroughly familiar with the subject believe that they can make the project a success and decide to go ahead with the project, is the engineer warranted in undertaking the work? Questions in Ethics 77 (b) If in the opinion of the engineer the possibilities of profitable de- velopment are more or less uncertain and the success of the development depends upon circumstances which may or may not render the project un- profitable, is the engineer warranted in undertaking the work? 15. A manufacturer offered an engineer a commission of ten per cent on all the material that might be used on a contract, provided his special brand of material was specified. If the engineer knew or believed that the material was equal to any similar material on the market, would he be justified in ac- cepting the offer, and why? 16. Would he be so justified if he knew the material was equal to any on the market, and would not cost more than other materials of the same kind? 17. If a similar offer were made to a contractor to specify certain ma- terials with his bid, would he be justified in accepting the same, and why? 18. A company asked two engineers to name the price at which they would agree to prepare plans for a certain piece of work. Each engineer, without knowledge of the other, estimated that the work should reasonably be worth the sum of $2,000, at which price one of them submitted his prop- osition. The other, before submitting his proposal, accidently heard that the same price had been named by his competitor, and being desirous of se- curing the work, reduced his price to $1,900. Was he justified in such reduc- tion, and why? 19. If the above work was worth $2,000' a current professional charges, and an engineer knowing this and without knowledge of the price named by others, was so desirous to secure the work that he was willing to reduce his charges to $1,500, would he be justified in such reduction, and why? 20. An engineer was about to let a contract for certain expensive machin- ery. He was very familiar with similar machinery made by a number of first class manufacturers, but was unfamiliar with that made by one concern whose reputation was, he knew, first class. The company, anxious to stand on an equal footing with others, offered to pay all the necessary expenses of the engineer to visit several places where their machines were in use, including a trip to their factory where a similar machine was under con- struction. If the engineer desired such information, and could conveniently make the trip, should he accept or decline the invitation, and why? 21. If the engineer made the trip above outlined, either at his own ex- pense or at the expense of the company, and during the trip was invited by the representatives of the company to take various side trips for pleasure and to accept various costly entertainment at the expense of the company's representatives or of the company itself, should he accept or decline, and why? 22. Should an engineer accept, to any extent, minor favors (cigars, theatre tickets, etc.) of a contractor or those who are liable to become con- tractors on his work, and if so, to what extent? 23. A contractor named a price of $50,000 for performing a piece of work for a company, for which he was willing to take the Company's notes. The notes, he found, could be discounted at the local bank so as to net the con- tractor $49,000. The manager of the company, after consulting with the cashier of the bank, offered through the cashier to award the contractor the contract at $52,000, provided he would allow the bank a total discount at the 78 Personal and Ethical Relations bank of $3,000, in which event the contract would still net the contractor $49,000. Should the contractor take the contract under such conditions, and why? 24. If under the above conditions the cashier advised the contractor that the manager was to receive half the discount which the bank made, what should be the contractor's attitude toward the contract, and why? 25. An en^neer of reputation was asked by a banking- house to take charge of certain engineering work, no price being agreed upon for his sal- ary. He by chance learned that the bankers would not object to a charge of twenty-five per cent in excess of his regular charges. Would he be war- ranted in increasing his charges beyond his usual basis? 26. In a similar case, a company was so desirous of an engineer's serv- ices that they offered him fifty per cent more than his customary charges. He would have been glad to accept the appointment at his regular charges. Was he warranted in accepting the advance? 27. An hydraulic en^neer, under an agreement with a village, prepared plans for a water works system. To pay for a part of the work involved, village bonds were issued. The official of the village asked the engineer if he would assist them in the disposal of the bonds, and he agreed to do so if he conveniently could. He spoke to several bankers, who did not care to buy the bonds, and finally meeting the representative of a bond house, told him of the bonds which the village desired to sell. The bond house purchased these bonds at a price mutually satisfactory to themselves and the village. Afterward the president of the bond company, meeting the engineer, told him that they had bought the bonds at a very satisfac- tory price, and asked him to call at their oflBce as the bond company desired to give the engineer a check for one hundred dollars. Should the engineer have accepted or rejected the check, and why? 28. Toward the close of the construction season the authorities of a small town became very anxious to complete certain paving that year. An engineering company made a proposal to the town to prepare plans, specifications, and estimates for this work and in case no bid was received below their estimate, to take the contract at the estimate they had made. Was such a proposal ethical? 29. Certain promoters negotiated a franchise with a city to build an important public work at an expense of about $1,000,000, payable in an- nual installments which were to begin on the satisfactory completion of the work. The franchise was granted. One of the promoters withdrew from the venture accepting for his share of the prospective profits and for his expense and time, an order payable from the first moneys received from the city. A corporation was formed to undertake the work which was financed not by moneys furnished by its stockholders, but by bonds which were sold to the general public mostly outside of the city. The company attempted to build the works on inadequate plans. The works as carried out were unsatisfactory, the available funds became exhausted and the pro- ject was placed by the court in the hands of a receiver. The promoting- company having failed in their efforts and having no further resources abandoned the project, leaving the contractor and the bondholders and cer- tain creditors with an uncompleted plant practically valueless in its un- finished condition. Questions in Ethics 70 A consulting engineer was called in by the city to review the situa- tion and advise as to what was necessary for the proper completion of the l-roject. He completed his report which was received with confidence by the public, was paid for his services and had no further professional connection with the city government which had employed him. The promoter who had withdrawn from the project at the beginning, began negotiating with the city to be allowed to proceed with the comple- tion of the work which he proposed to do on lines much less thorough and complete than those proposed by the consulting engineer, and undoubtedly with the hope that he could protect the interest he already had in the ven- ture and perhaps secure a considerable extra profit. It was obvious that if he could secure the services of the consulting engineer who had reported to the city as his advisor it would give him a certain prestige with the officials and the citizens of the city, and help him in securing the desired franchise. He approached the consulting engineer with this proposal. Should the con- sulting engineer accept such an appointment? 30. A agreed to buy a farm of B for $5,000, paying $1,000 cash, and made a written agreement to meet B on a certain date and either complete arrangements by giving a mortgage for the balance or to forfeit the amount paid. Before the date of meeting, B, relying on A's agreement, refused an- other similar offer. A, on account of sickness, failed to meet at the ap- pointed time, and on account of ignorance failed to be represented by at- torney. B was undoubtedly damaged only $300 or $400 by failure to sell. By failure to meet his agreement, A legally forfeited his payment of $1,000. Assuming that A was willing to forfeit a sum equivalent to the actual dam- ages, was B morally warranted in holding A to his agreement? 31. Assum.e that a body of some five or six men undertake to form a joint stock company in a line of business with which they are familiar. On account of their knowledge and reputation for fair dealing, they secure sub- scriptions to the stock of the company and organize the same. A board of directors is elected, consisting probably of the original organizers of the company who must also be stockholders. During the early stages of devel- opment, the future of the company is more or less uncertain and the prob- able outcome will be better understood by those closely connected with the management. The right to buy or sell stock is an undoubted legal right which can be exercised by any of the stockholders at any time. Would the original promoters be justified in selling their stock as soon as the com- pany is organized? 32. Would any of the stockholders be justified in the sale of their stock before the prospects of the company are fully realized? 33. Would any member of the company, be he director or otherwise, who is particularly well informed on the business of the company, be justified in purchasing stock from other members less informed, at less than its fair value by withholding a knowledge of favorable prospects or by unduly deprecating future prospects, and why? 34. Would any stockholder be justified in undertaking to purchase a majority of the stock from other members in order that he might person- ally sell it at a price greater than its true market value, and thereby place the control of the same in the hands of strangers, and why? 80 Personal and Ethical Relations 35. Would any stockholder, after acquiring a majority of the stock, be justified in selling said majority to strangers without securing the right of sale to other stockholders of the company, and why? 36. A, who controlled fifty-one per cent of the stock of a corporation, elected himself president of the company and voted himself a salary which will be approved by a court as not excessive but may be more than the work is worth. Is he warranted in using his legal rights to secure an ex- cessive salary? LITERATURE Suggested Code of Ethics of the Oregon Society of Engineers. Eng. News, June 12, 1913.

CHAPTER V THE USE OF ENGLISH § 43. The Importance of English. — The successful engineer must be something more than a skilled mechanic, an artisan or a de- signer. He must not only be able to make surveys and prepare plans and designs but he must also be able to make reports to his clients or superiors, prepare instructions for his assistants and subordinates, write specifications, prepare agreements, both as a basis for receiving bids and for making contracts ; he must originate, lay out and supervise or carry out contract works, and supervise the maintenance and operation of engineering plans. In each case the engineer must be able to ex- plain his plans and proposals so that his reasons and methods will be understood and appreciated. The ability to use clear, logical, forceful and correct English is an asset of great value to the engineer, and frequently means advance- ment beyond others of equal technical ability but without the ability of correct and proper expression. Obscure, incorrect and fau-ty language, used in engineering re- ports, instructions, contracts and specifications, frequently involves dis- putes and litigations, with the consequent loss of thousands of dollars, and in some cases misunderstandings which may cause the loss of lives and reputations. Any element in engineering education, the misuse of which may produce such dire results or the correct use of which may bring such great results, is worthy of the most careful consideration and attention. The command and intelligent use of language is often the best method of conveying to others an appreciation of the knowledge of the engineer and his ability to meet and solve engineering problems. For success the engineer must not only be technically ab^e to solve the engineering problems which come to him for solution, but others must know and appreciate his ability. It is true that the best test of ability is the actual performance of the work in question, but a knowledge of the ability so demonstrated is confined to the clients, employers, friends, colleas^ues or employees of the engineer, and a wider knowl- edge of that ability can be secured only by the spoken or written word. Articles in the technical press or papers before engineering so- cieties, describing new designs and new work along new and novel lines, when well prepared and presented, extend the acquaintance and reputation of their writer. The preparation of an article or paper, on a 82 The Use of English subject on which he is partxu'arly well informed, systematizes the engi- neer's knowledge, gives opportunity for a careful review and per- sonal criticism of his own work, develops his ability, and aids himself more than it does any other individual. When such articles or papers are of real value, they also aid in the advancement of professional knowledge and fulfill a duty every man owes to his profession. When such articles are prepared purely from a selfish motive, for the purpose of advertising and personal advancement, they are usually valueless to the profession and detrimental to the author ; but when prepared with the purpose of conveying valuable information and advancing the pro- fession, if well prepared even though the subject be a simple one, they become a valuable asset to the profession and a legitimate aid to individual advancement. § 44. Engineering English. — Engineering English should and does differ from the English of literature. Fine writing and pic- turesque language have little place in the writings of the engineer. The language should always be clear, definite and exact ; it should often be brief, technical and to the point. It must vary in its character from the English of literature to the English of the law, according to the persons for whom and purposes for which it may be prepared. In gen- eral, engineering English must be written with the particular parties in mind for whom it is intended, and their education, training, technical knowledge and point of view must be fuMy considered. Engineering writings may be subdivided into several classes, each more or less distinct, but such writings may frequently fall between or within more than one of these classes, and sometimes partake of the character of each. In general, letters, reports and papers may be written for : First: Non-technical readers. Second: Technical readers more or less acquainted with engineer- ing matter but not particularly versed in the special subject treated. Third: Supervisors and assistants, those specially acquainted with the subject matter treated. Fourth: Contracts and specifications. § 45. The iHearer or Reader. — The knowledge and capacity of those to whom written or spoken language is addressed is an important element to be considered in the preparation of articles, reports or ad- dresses. The statement that "doubling the head of water acting on a S^iven turbine will increase its power more than 28 times, because such power will varv with the three-halves power of the head acting," is a perfectly clear statement to the hydraulic engineer but may mean little to a business man, and must be stated in greater detail and with con- The Hearer or Reader 83 siderable explanation if it becomes necessary or desirable to have the business man understand and appreciate the fact. In such writing technical matters should be explained in clear and simple language, so that the persons for whom it is written will understand the matter in- volved, the reasons for the plans proposed and the results to be accom- plished. There are few technical matters which cannot be made so clear in a properly written paper or report that any good business man can understand them, and failure to prepare such papers that they can be so understood is usually due to a lack of understanding of the matter by the engineer himself. Any engineer has only to attempt to read some advanced work on a subject with which he is unfamiliar to recognize the fact that, while such a work may be perfectly plain to the expert, it is quite meaningless to the novice who must first read ele- mentary works on the subject and acquire the fundamental ideas and the necessary vocabulary before he can comprehend the advanced work. Papers on technical subjects must therefore be written with the capacity of the reader in view. For the business man, the conclusions are most important, but they should be supported by such a clear dis- cussion of the facts and such a presentation of logical arguments as will appeal to his judgment and common sense. The principles by which the conclusions are reached, and the detailed data to which they apply, are less important but should usually be presented as a basis for the conclusion. When the paper is prepared for technical readers who have had a certain technical training, and are known to understand certain scien- tific principles, the matter may be presented in a different form and the special matters described must be so treated as to make them plain to others than the specialist. In such cases the discussion of the data and the principles on which the conclusions rest, becomes the important matter to be considered, and the explanations are needed only of those technical details that are special to the subject and are not coinmonly understood by the general professional man. When those addressed are specialists in the matter discussed, the data obtained and the methods of their derivation and investigation be- come of primary importance. Technical terms properly applied will add to the clearness of the exposition, and conclusions when drawn must be the obvious deduction from the data and the facts. In the writing of contracts and specifications, which in the execu- t'on of the work must usually be interpreted by men of varying capa- bilities and which may be and frequently are, subject to the interpre- tation of the court, the words should be as carefully chosen to express the exact meaning as are the mathematical symbols in an equation. 84 The Use of English There should be but one interpretation and that the one intended, and the exact meaning of both the common and technical words or terms used and their local or special significance should be thoroughly un- derstood and appreciated. The use of the technical vernacular of the subject treated is desirable when it adds to the clearness of the meaning. Ordinary words and terms must be used with great care, and fre- quently must be modified and defined so as to assure an exact interpre- tation of their meaning. § 46. Knowledge of Subject. — The absolute prerequisite for clear and accurate technical writing is a clear and accurate knowl- edge of the subject which is to be discussed or described. While this is self-evident, lack of such knowledge is nevertheless an important rea- son for much and perhaps most of the obscurity in reports, technical papers and specifications. If a specification must be prepared or a tech- nical detail described which is imperfectly understood by the writer, how then can it be made clear to others? It is impossible to convey a true idea which is not possessed by the writer, and the idea con- veyed can never be clearer than the writer's understanding of the matter described. It is evident that the engineer who wrote the specifications for the measurement of earth in embankments d'scussed in Section 51, did not fully and clearly understand or appreciate the element of shrinkage as affecting the measurement of earth fills and entirely failed to conceive the conditions under which such measurements might have been made. If these subjects had been understood, the necessity of an appeal to the court would have been avoided. Accurate anl vocabulary is ^he direct study of the words and terms used in any special vocation or business when such information is accessible. The reading of the various technical papers and the proceedings of the various societies which cover or include the special subject in which infor- mation is desired will often furnish valuable additions to the vo- cabulary. The use of standard dictionaries is of little value in this Literature S*? study as the definitions given are too general. Some valuable work is being done by various technical societies in the definition of tech- nical terms and the establishment of uniform practice and this work should be closely followed.

Importance of Properly Written Letters. — Usually the first introduction of the engineer or architect to those from whom he de- sires employment comes through the spoken or written word, and a clear and concise statement of his claims to employment, of his educa- tion and previous experience, presented in proper form, is an impor- tant element in securing the position he desires. A letter poorly writ- ten, poorly worded, mispelled, ungrammatical, improperly punctuated and illogically arranged, marks the writer as careless and more or less ignorant and is an unfortunate introduction. Personality in a personal application may to some extent overcome ungrammatical and incorrect language, and at least the spoken word leaves no lasting record behind ; but a poorly written letter may pass from hand to hand and may leave an enduring record of incompetency. In later business and professional life, the art of letter writing is of no less importance. The impression conveyed by a clear, concise and properly arranged letter is of great advantage, and business trans- actions are greatly facilitated by such letters. Much time is often lost through careless letter writing where the failure plainly to state the facts which it is desired to communicate, necessitates a request for ex- planation or further information. § 55. Business Letters. — In the writing of business letters, certain more or less formal methods of arrangement have been gener- ally adopted and the use of such arrangement is desirable as showing the familiarity of the writer with good usage. The principal require- ments for the proper preparation of a business letter are as follows : Heading. — The address in the heading should always be suffi- ciently complete for postal purposes. If a street and house number are necessary, they should precede the name of the city, but the date should come afterward and not before. It is desirable to use the name, not the number of the month ; the number of the day of the month, and the complete number for the year. The day of the month and house number should be Arabic numerals, but street numbers if less than one hundred are usually spelled out. Abbreviations. — While for formal letters it is perhaps more digni- fied to avoid abbreviations in both the heading and salutation of the 100 Letters and Reports letter and in addressing the envelope, it is both permissible and desir- able to use such abbreviations in business letters for the name of the months and of the states. Address. — The salutation address may omit the street and house number, but the name of the city and state should always be included in formal letters and the title "Mr.," "Messrs.," etc., should always be used as a matter of courtesy. Salufafion.— Use the form "Dear Sir," not "My Dear Mr. ," unless you are quite intimately acquainted with the party to whom the letter is written. In official communications and letters to Govern- ment officials, use the still more formal "Sir." Subject Heading. — The use of a subject heading in all business let- ters is very desirable. Its use in applications for employment is ad- vised as it gives the idea of familiarity with business methods. It should be placed at the right and just above the body of the letter, as follows : "Application for Employment." For examples of the proper form of business letters see Section 59. § 56. Suggestions Concerning Letters of Application for Em- ployment. — Great care should be used in writing letters of applica- cation for employment. The handwriting shows character and is often required in applications for positions. For this reason such letters should be written, not typewritten, unless unfortunately the handwrit- ing is so poor as to make such a form of application hopeless. It should be borne in mind that the prospective employer probably has no knowledge of the applicant other than that afforded by the let- ter. The success of the applicant will depend upon his creating a fa- vorable impression and to this end neatness, proper form, good gram- mer, correct spelling, definiteness of expression and good composition are highly important. The qualifications of the applicant should be presented fully, clearly, concisely and logically. The paper used should be of commercial note size, and of good quality. Scrap paper or paper punched or specially ruled for tech- nical work, is unsuitable. The writing should not be crowded and should be properly centered on the sheet. The young engineer, especially when just graduated, should not be too ambitious in his application for work and should not limit too closely the character of work for which he applies. Un- less he has had considerable experience, he should not apply for a position as a "civil engineer," "electrical engineer," etc., but for a "position" or a "position as assistant." He may give an idea of the work which most interests him, but should express his willing- Application for Employment 101 iiess to accept any reasonable position as he is seldom qualified or in position to command any important place on an engineering staff. When the young engineer has done previous work, his former salary may be mentioned, but otherwise the matter of salary should be left to a later communication. He should not give the idea that the question of salary is first in his mind. § 57. Important Suggestions. — Economy and efficiency in the use of language are essential in letter writing as in other engineering writing. After writing a sentence : (i) See how many words can be omitted or changed, leaving the meaning clearer and stronger. (2) See how the same idea can be expressed in better and clearer terms. Do not write : *'I wish herewith to enter my application for" "I hereby wish to make application for" "Allow me, respectfully, to offer myself as an applicant for" "I would like to enter an application for" "I wish to take this means of applying to you for" Instead of the above write : **I respectfully apply for" Statements should not be too blunt. It is unnecessary to write : "I have not had any practical experience." Write prefer- ably : ''My knowledge and experience are limited to my work at the university." References. — Avoid, "For references I suggest the following" or "Please refer to the following :" Use instead "I respectfully refer you to ." Reference to a school college or university is improper. Refer to some particular teacher, professor or official of such institution. Reference to a bank is proper for financial standing. For personal standing, the name and position of an official should be given. In personal applications for work, open letters of recommendation are of little weight. They are, of course, favorable or they would not have been written or presented. The employer usually prefers a per- sonal and private letter addressed to himself from some one of standing or reputation. He has probably written too many general open letters of recommendation himself to have much confidence in them. Most po- sitions are secured by personal applications, and too much must not be expected from general letters of application although they frequently result in uncovering vacancies for which personal aT^p'^*'\i^'o!": r^ o'lld usually be made. 102 Letters and Reports Finally. — The letter should be reread after it has been written to see that no essential word or words have been omitted or misspelled and to see that it is signed. Omitted words and especially an omitted signature, show carelessness that is not a good recommendation for a position. Further details of the general subject of letter writing are given in the following discussions. § 58. The Employer's Viewpoint. — Mr. C. A. Bock, Secretary of the Morgan Engineering Company, as a result of an examination of over 3,000 letters of application, embodied his views in a letter that is so pertinent that it is here abstracted at considerable length. (See Eng. News, Vol. 76, p. 258.) "In the applications from college graduates common faults are poor spelling, careless handwriting, lack of definiteness, poor composition and a generally slovenly appearance. While it is not to be expected that a young and inexperienced man will turn out a faultless composition, it is assumed that if he has potential ability he will not exhibit gross carelessness in a let- ter of this kind. The habit of error and carelessness is particularly dis- qualifying for engineering work and will not be tolerated by competent engi- neers. "The applicant's greatest difficulty probably arises from his inability to appreciate the employer's view point. He should remember that all the em- ployer has to judge from is just what he sees in the letter. If he sees poor writing, spelling and diction, lack of definite information or meager informa- tion, presented in a disorderly manner, it is but reasonable to expect that he will form an indifferent opinion of the writer's ability. It is usually desired that the first letter give full information as to the applicant's qualifications. While often a number of letters may be exchanged before the man is engaged, the first letter makes the greatest impression. "The applicant must ask himself just what are the things that the em- ployer would want to know about the man he wishes to employ. He must analyze the requirements of the opening he wishes to fill and then set forth his qualifications logically, in the order of their importance. This does not mean that qualifications should be manufactured to meet the requirements, nor that he should unduly enlarge upon his previous experience. Such ex- pedients generally are very easily detected and reflect little credit on the man who resorts to them. ^ "The letter should be concise and come to the essentials without prelude, but must not be brief to the point of sacrificing pertinent information. A common mistake is that of devoting a long paragraph to stating that "I real- ize that a large number of applications will doubtless be received and that it will require a great deal of your time to read through them all, and it will probably be very difllcult to decide," etc. Simple, direct statements, neatly written in well-balanced sentences, will nearly always make a favorable im- pression, and much can be accomplished by logical paragraphing. Application for Employment 103 "A very short letter is not likely to accomplish much for the writer unless he is already personally known. Single-sentence letters or brief inquiries asking detailed information concerning the vacancy and telling nothing of the writer's qualifications at once give the impression that he would be more interested in personal advantages than in serving his employer and that he is not over-anxious to secure the position. * * * "Many capable and deserving men, do not realize the bearing that the writing of an application may have upon their prospects. Men of indif- ferent ability frequently secure positions simply through a favorable presen- tation of their supposed fitness, and it is often the case, especially with younger men, that the one who makes the neatest and best presentation of his qualifications secures the position rather than the one who has greater ability, but lacks the faculty of presenting his qualifications. In replying to an advertisement or to a letter, any requests for certain items of information should be fully complied with. A point illustrating this requirement which has repeatedly come to the writer's observation is the fact the draftsmen, when asked for a small sample of their lettering, seem to think it necessary to submit several large bulky drawings * * * instead of submitting a smaller sheet that would easily contain a fair sample of their work." * * * Commenting on this letter the Engineering News states editori- ally: * * * "Mr. Bock's suggestions, are likely to be found useful, not only by the large crop of June graduates of the present year, whom he mentions in his opening paragraph, but by many engineers of experience and high standing. "It occurs to us, in this connection, to add to those given by Mr. Bock, another useful hint that we happen to know has been found helpful by many engineers inexperienced in going about the task of seeking a position. Our suggestion is that the engineer who is seeking a position should prepare a letter setting forth in fairly complete form just what his professional ex- perience has been, including in this, of course, a statement as to his educa- tion and personal characteristics, such as a prospective employer would de- sire to have. A list of references, stating in connection with each reference just what particular part of the applicant's experience or characteristics it treats of, should also accompany the letter. "This otatement should be neatly typewritten on good paper of standard letter size, and a copy can then be inclosed with any letter of application or reply to an advertisement. In this way the letter of application itself can be made brief and businesslike, and can emphasize any special fitness which the writer may think he possesses for filling the particular position to which the letter relates. At the same time the employer is given all the facts con- cerning the applicant that he is likely to need, in a form where they are readily filed for examination." * * * * See Eng. News Vol. 76, p. 275. § 59. Examples of Letters of Application for Positions. — As examples of letters of application which are fairly satisfactory, several actual letters are here given in a slightly modified form. 104 Letters and Reports Example A 1312 South Street, New York, February 8, 1914.

The Importance of Good Reports. — Few technical men have ever reached more than subordinate positions without the ability to prepare a fair technical report. This is the most common form of technical writing and, excepting contracts and specifications, the form most important to the engineer. There is no writing on which his suc- cess so largely depends as on the preparation of neat, clear, logical, con- cise and complete reports. The advancement of that engineer is assured who can clearly comprehend the conditions of a problem and the factors which modify and control its solution, and who can transfer his ideas and conception of those factors and conditions and the logical conclusions to be drawn from the same, to his superior or to his client in a clear and ex- plicit manner so that every fact and condition becomes plain, every controlling circumstance becomes apparent, and every conclusion be- comes obvious. The engineer should give special attention and spe- cial study to the principles and preparation of reports on account of the undoubted influence of this work on his future. § 61. The Purpose of Reports. — A report is an oral or wTitten statement of principles, facts or conditions made to show the necessity or lack of necessity for any usual or unusual course of action. The function of the report is to point out plainly, so that those for whom the report is prepared can understand, the facts and conditions neces- sary to be known in order that suitable action can be taken. Reports may cover any part of the technical field and in any general treatment of the subject it is impossible to more than impress the fact that most of the requirements for technical writing and for the writing of specifications discussed in Chapters V and XV need to be especially emphasized when applied to the preparation of written reports. Dif- ferent reports will require very different methods of treatment. They are usually designed to be specific and confined between very definite lines, although the field covered mav in some cases be verv broad. It is always desirable that the instructions on which a report is to be based should be in writing and should specifically define its desired extent and limitations, otherwise the point of view from which the re- port is to be made or the extent of the investigations necessary for its purpose may not be understood and the report may be unsatisfactory, incomplete or involve unnecessary time and expense. Like all other technical writing, to be of value a report must be based on a thcrough knowledge of the subject, and such knowledge Technical Reports 107 must be specifically detailed and complete on account of the specific character of the report. An equally important condition is clearness. The findings and conclusions must be manifest and beyond question to the minds of the reader who may or may not have technical knowledge. If the report cannot be undersood by the man for whom it is prepared, it is useless or worse for it may, if misinterpreted, be misleading and add to the confusion instead of clearing up uncertainties, which is its main object. § 62. Preliminary Consideration. — Before an investigation is undertaken a thorough consideration should be given to the instruc- tions which outline the purpose of the report, and to the various factors which must be the basis of the desired report. It is desirable to out- line the various conditions and pertinent data which would in any man- ner affect the project, and which should therefore be investigated or se- cured in order that a clear understanding may be obtained and logical conclusions reached and demonstrated. In this way the opportunities for error resulting from overlooking essential elements in the problem will be largely obviated. As has already been indicated, many subjects quite foreign to the technical side of the question will frequently have an important bearing on correct conclusions, and failure to give such sub- jects due consideration is the cause of many unsatisfactory and errone- ous reports. There is always danger that the expert may become interested in the particular subject of his specialty and lose sight of the fact that there are other subjects of equal or perhaps greater importance to which his attention should also be directed. In contemplating some form of engineering or architectural construction, the technical man is largely interested in ways and means. His client is only interested in results. While the client may desire to know the details by which the results are to be attained, his principal interest lies in the answers to the questions : "How much will it cost ?" "When can it be completed ?" "Will it accomplish its purpose?" If these questions can be answered satisfactorily, he is willing to leave all technical details to his profes- sional advisers. § 63. Ethical Considerations. — In reporting on designs, struc- tures of projects of other engineers, captious criticism should be avoided. A report is not the place to show the superior knowledge or ability of the writer needlessly or to attempt to win over the clients of other engineers. If results can be accomplished safely and economi- cally by the method proposed, even though in the opinion of the re- porter a better design might be possible, it is generally undesirable to 108 Letters and Reports advise unessential or radical changes which will result in no material betterments. The engineer may be called to report on some single phase of a project such as its safety, or on some particular part or equipment on which he is supposed to be particularly well informed. In such cases he should avoid interference with other phases of the work on which his opinion is not requested. There may be exceptions to this state- ment should the examination develop the existence of radical errors which may endanger the structure or the life or property of others or should the reporter become aware of gross fraud or dishonesty. He may under such conditions owe it to the public to take such action as will prevent such danger or the accomplishment of such fraud. This is a condition which requires the greatest tact in its treatment and should in general be handled without publicity, an appeal first being made to those who are directly interested to take such action as will prevent the serious results of the proposed construction or transaction. Such appeal may be enforced by a decision to publish the facts if they are not equitably adjusted. It is perhaps needless to say that such a stand should be taken only when the conditions are such as to warrant such radical action. § 64. Investigations and Estimates. — Proper reports must be based on a suitable investigation of the subject, and this must be made as complete as the purpose of the report will warrant. Nothing that can be determined must be assumed, and the reporter must use the greatest of care to make sure that the ideas and opinions which result from his investigation are not colored by his personal bias (see Sec. 12). When reports are of a preliminary nature, the extent of the inves- tigation must be limited but the essential facts and conditions should be properly determined and due allowance must be made for all uncer- tainties (see Sec. 244). Reports will frequently require estimates of the cost of construc- tion or of development and possibly of fixed charges, operating ex- penses and cost of maintenance as well as an estimate of probable in- come. Such estimates require careful consideration and much fore- thought. They must, in a preliminary report, be based on incomplete data. Contingencies of various kinds will surely arise and must be sufficiently foreseen and provided for by conservative estimates (see Sec. 252). A thing that is worth doing at all is worth doing well, and this prin- ciple is especially true in making reports. A cursory examination or a failure to give the matter under consideration careful and complete in- vestigation, with resulting conclusions based on insufficient or incom- Successful Reports 109 plete data, will most likely be misleading and may result in overlooking serious contingencies or favorable facts and conditions. Such a report may lead either to expensive investments that will be found entirely unwarranted when a thorough examination is made or in the condem- nation of a worthy project. Every report should be so thorough and complete that the accuracy of the conclusions will be assured. § 65. Elements of Successful Reports. — Most reports depend for their value on accuracy of observation and correct deductions. They often require great technical knowledge and skill and frequently a wide practical experience. There are usually certain very definite facts or conclusions which are the essential features around which all other facts and deductions should be centered and to which they are subor- dinate. Special effort should therefore be exercised to bring out and accentuate these important ideas and to facilitate the appreciation of their bearing and importance. Clear, explicit and exact statements are of special importance. Proper arrangement will not. only save much time to the reader but will emphasize the importance of the main ideas and the relation of the subordinate factors. When it becomes desirable to recite all the facts and conditions in great detail, the essential mat- ters pertinent to the immediate purpose of the report should be em- phasized so that their importance can be distinguished and the logical conclusions made manifest. The technical report is often the pioneer report on the sub- ject; later the legal and other aspects must be examined and passed upon by specialists in each line, but in its preliminary stages, the en- gineer must frequently look into each phase, and if his report is to bear expert scrutiny it must be based on a broad understanding of many things. In the preparation of reports on technical projects, the engineer needs more than technical training. In such projects, questions of law, business, transportation, market conditions, manufacturing, agricul- ture, politics, economics, finance and many other factors may be of even greater importance than the technical factors involved. Every engineer who is called upon to report on the feasibihty of a project must duly consider not only the technical problems involved but also all other aspects, for the practical and economical success de- pends on its feasibility from every point of view. The project is not a success simply because it is well and economically designed and properly constructed, but it must also be successful from commercial and financial standpoints. 110 Letters and Reports Numerous projects in water power, irrigation, drainage, manu- facturing, etc., have resulted in failures because some necessary phase has been overlooked and remained unconsidered. A report may be complete, it may be technically correct, it may re- cite all the facts and discuss all conditions and details, and yet it may be a practical failure if it does not recognize the human side of the prob- lem and differentiate the essential details in such a manner that the every day business man, the director, the banker or the citizen may ap- preciate the essential facts and the logical solution of the problem. A scientific statement of fact or principle may be satisfactory if the report is made to a technical superior but it may be meaningless if made to a layman. It is the business of the engineer to translate the scientific statement into such language that its practical significance can be fully understood by the reader with the degree of knowledge and un- derstanding that he possesses. It is seldom necessary to demonstrate the principle or prove the fact ; these will be assumed as correct on the basis of the technical knowledge, experience and reputation of the re- porter, but their bearing on the issue involved must be so stated as to be readily comprehended. It is often essential that the report should include all of the data on which discussions are based. These data and their bearings on the proj- ect discussed and the reasons for the opinion expressed should be clearly set forth. In a well drawn report the engineer can usually so illustrate and describe the conditions by which a project is modified and con- trolled, that any good business man will understand the basis on which the opinion rests, and the degree of probability of any departure from the expected results. While a similar comprehension by nontechnical readers is not to be expected in regard to the technical details, an un- derstanding of the general considerations on which the feasibility of the project depends can be secured. If a report can not be so drawn it is usually due either to insufficient data or to the fact that the en- gineer himself does not fully understand and appreciate the logic of the situation. For simplifying scientific facts, principles and data, graphical dia- grams are of great importance. They give a significance to figures and data which is not otherwise apparent. The report should usually be accompanied by such maps, draw- ings and sketches as may be necessary with the data furnished, to illustrate clearly the conditions and show conclusively that the condi- tions are such as the report sets forth. Literature 111 In most cases facts and data should be given in such a manner that the report may be checked up by others who are informed on the subject and the conclusions given in the report should be such as will be demonstrated clearly by the facts in the case and the available data. Reports should never consist of general conclusions or mere opinions but should be the logical outcome of facts, conditions and data. In general it is essential that the report itself should be clear, con- cise and definite in its statements and recommendations. Any elabo- rate discussions of voluminous data should usually be contained in the appendix to which the main report should refer for confirmation of its facts and recommendations. Even under such conditions it is well to summarize the conclusions and such a summary may be introduced in the closure of the report or may sometimes be included to advantage in a short letter of transmittal, which may be used as an introduction to the more extended treatment in the report.

Origin of the Present Civilization. — The present state of mental and material development of the nations of the earth is the re- sult of influences many of which may be traced back to the dawn of history. Men and nations, and their laws, customs and relations are not alone what modern civilization has produced but have been created by influences which have been acting from the most remote times. The heritage of today, the social, political and religious institutions are due to many people and to other nations, many of which have long ceased to exist but which nevertheless have left an indelible impression on present social, political, mental and moral development, and on the thoughts, acts and daily lives of present generations. Those who read Draper's Intellectual Development of Europe, or White's Warfare of Science and Theology, will find these influences pointed out as they have affected certain lines of modern thought, and will realize that advancement in all lines is the result of many influences which have modified old ideas and old relations and have been largely instrumental in creating the present conditions which now obtain in every country. § 67. Law an Evolution. — It will be found that the laws of to- day which guard our rights and privileges and limit and control our ac- tions, were not created entirely new for the particular needs of the present time, but have descended from the past, changed and modified as necessities have demanded but still having their root, their origin and foundation in the past. The term "law" is familiar in numerous applications, having al- ways, however, a somewhat similar signification. Technical students are perhaps most familiar with "natural laws" on which the sciences are based. A knowledge of such laws is a most important element in technical education. Engineers and architects study the laws of mechanics, the laws of electricity, of cherriistry, of physics, and of the various other subdivis- ions of science. The lives of most engineers are largely spent in in- vestigating such laws and in utilizing them for the accomplishment of desired results. Such laws have been slowly derived but not created by man, they are fixed and unalterable and are never broken. Law an Evolution 113 Plants and the lower animals follow the natural laws of growth and development and the instinct which is also their established natural law. Mankind is also influenced and controlled more largely by nat- ural laws than many are apt to realize. Heredity, environment, edu- cation, all affect every action and every thought and opinion. That which is termed moral law may be defined as the general moral tone or feeling of a community to right and wrong action. The punishment for neglecting or disregarding moral law is public disap- probation, contempt or ostracism. It changes to some extent with every decade, and differs with different^ time and different nations. Divine law is believed to have been received from Deity and forms the basis of all religion, and probably has had greater influence on human actions than any other except natural laws. The divisions of laws which may be termed human laws and which are intended to influence or govern human actions, are somewhat dif- ferent in character. ]\Iost of these laws are not unalterable nor un- changing ; nor are they always obeyed. These laws man has seen fit to establish for his own guidance and .protection to enable him to live in safety and at peace in the enjoyment of such rights and privileges as his state of civilization has made possible. § 68. Development of Human Laws. — Primitive man lived- en- tirely under natural laws. He obtained those things which his strength and agility would permit ; with him, as with the lower animals "might made right" and his existence was largely a continuous struggle. The rights and privileges of primitive society, in the family and the clan, were established by custom. Whatever was customary or usual was considered right, and ultimately became law. With man's mental development he began to realize that his individual instincts and in- terests were hardly sufficient for his guidance. He began to see that his neighbors had rights equal to and often in conflict with his own, and that unless he wouM live in constant warfare, it was absolutely essential that the rights of all be so regulated as not to interfere, or so as to interfere as little as possible, with the rights of others. In order to protect himself in the enjoyment of his own property and rights, he was obliged to make laws for the regulation of his own con- duct. Early laws were largely based on custom or on the opinion of the head of the clan or tribe, and were not always just or equitable as may also be said of some of the laws of the present day. These laws have grown, developed and have been altered and expanded as the races of mankind have grown and developed and experienced new demands for the protection or extension of their social, political and business re- 114 Origin, Nature and Development of Law lations, and they constitute today the vast legal fabric which controls and modifies every line of civilized human activity. There may also be mentioned international law which consists of the rules, precedents and customs by which independent nations govern their dealings with each other. § 69. Municipal Law. — The subject which is particularly im- portant to discuss here is municipal law which consists of those rules by which the civil rights and conduct of the citizens and residents of a nation with each other are regulated. Municipal law may be subdivided into written law and unwritten law. The former consists of those positive enactments of congress, of the state legislature, or of city councils, which are passed to meet some particular need or to effect some particular result. They sometimes simply affirm known principles of law and sometimes are passed to modify or nullify some particular established principle. For example, by ancient unwritten law a married woman could not hold personal property or make contracts ; now by enactment in most states her dis- ability has been removed and she can act as fully in legal matters as an unmarried woman. Unwritten law is the most extensive and the most important body of law. It includes the Civil Law and the Common Law. § 70. Unwritten Law. — Civil Law is the basis of the Contin- nental European Jurisprudence System and largely affects English and American law. It consists of the laws of the Roman people and the edicts of kinofs and of the senate, and of leg^al decisions and learned on'nions. This was codified by order of Emperor Justinian in the Sixth Century. The Justinian code was modified and reformed by Napoleon, is used m France today and is the basis of the laws of Italy, Spain, Ger- manv and Holland. The civil law was also brous:ht over to England bv William the Conaueror in 1066 and has had its effect on the laws of England. It has influenced the local laws of certain states through the earlv French and Spanish settlement. The common law of England was brought to this country by the fi r^t En «t-i o u o d Natural Persons (Individuals) r Relative Rights as to The Public { Courts People Other .Persons^ Husband and Wife Parent and Child Guardian and Ward Master and Servant Principal and Agent ^Partnerships Artificial Persons /Municipal Corporations (Corporations) \ Business Corporations Origin of Rights Constitutional Statutory Quasi-Contracts From Contracts Common Law rClassification/^^^^^'^^^^ t Personal Property Rights of Things (Rights in Rem) Private 'Wrongs (Civil Law) ^ Title Purchase Contract Inheritance Marriage Grant Judgment Occupancy Torts — Interference with absolute rights Breach of Contract Crimes Against Public Wrongs (Criminal Law) Is.

The engineer may so modify the conditions that the occurrence of natural phe- nomena will not be detrimental to human interests or so that their occurrence will be more favorable to human interests, as the case may be. 2.

CHAPTER VIII SOME LEGAL RELATIONS OF TECHNICAL MEN LEGAL RIGHTS AND RESPONSIBILITIES § 83. Employment in General/ — The employment of the techni- cal man in trade, business or professional work is a contract and must contain all the essential features of a contract. Such contracts are sel- dom written and are subject to the verbal agreements made when the employment is consummated. If the employment is for an indefinite period or is to continue so long as either or both parties are satisfied, it may be terminated without notice and without expressed reason. If a certain notice of termina- tion is required, such notice must be given by either party who desires its termination, except when the employee is discharged for cause. Employment for a definite period "unless sooner terminated" cannot be terminated prior to the end of the period without proper cause. If the employment is for a certain definite period and the period if allowed to elapse without notice, the law assumes a renewal of the con- tract for a like period. Contracts, not in writing, for services which cannot be rendered within a year are void,^ but if the services are actually rendered, pay- ment for such services can be enforced, not on the contract but on an inferred contract for benefits actually received. When a person is employed at a fixed rate (except the rate be for hours of service), and additional duties are imposed, he cannot secure extra compensation without an express agreement to that effect.^ To assure remuneration for services rendered it is important that the contract for employment be made with those legally empowered to make such contracts. The officers of a private corporation must be duly authorized by the Board of Directors to employ service or payment for such service may be avoided. The employment of an official of a private corpora- tion to do certain things which cannot be done without assistants, clothes him with authority to employ such assistants. 1 Engineering and Architectural Jurisprudence, by J. C. "Wait, Chap. 28. 2 See Statutes of Fraud, Sec. 107. 3 Waite, Sec. 810. Employment 127 The officials of a municipality cannot legally contract for services for the payment for which no appropriations are available. Occasionally engineers are employed in good faith on consulting work by municipal authorities, but no adequate arrangements are made for paying for their services. In some cases a certain appropriation has been made but this had been exceeded by the expenditures. In such cases an injunction will lie, preventing any payment in excess of the amount provided. While such an injunction is unusual, it is al- ways possible, and proper provision for sufficient funds should be made before the services are rendered. § 84. Discharge.* — Employment may be terminated by an em- ployer before the contract term of service has expired by reason of any of the following causes : 1. Willful disobedience to lawful orders. 2. Gross moral misconduct. 3. Habitual negligence. 4. Incompetency or incapacity. § 85. Professional Employment. — The relations of the profes- sional man to his client are confidential or fiduciary. To prevent un- due advantage from the unlimited confidence which such relations in- volve, the law requires the utmost of good faith in all transactions between the parties. In accepting service in a professional capacity therefore the individual also accepts certain responsibilities without a special agreement. The responsibilities legally implied in such cases are summarized by Wait as follows :^ 1. That he has the requisite skill and knowledge. 2. That he will use reasonable care and diligence in the exercise of his skill and in the application of his knowledge. 3. That he will use his best judgment ; and 4. That he will be honest. If the professional man neglects or fails to exercise any one of these requirements and injuries or damages result from such neglect or failure, he is liable under the law for such injury or damages. The law holds every man who solicits employment in any vocation or profession, responsible for the skill, ability and learning necessary for the reasonable performance of his work. Acceptance of employ- ment is a warranty that the employe is competent to do the work in a reasonably satisfactory manner, and that he will do it faithfully and *Wait, Sees. 802-806. "Wait, Sec. 831. , 128 Legal Relations in accordance with lawful direction. His liability is determined by his contract for employment, which service are rendered gratuitously or for a reward. If the client is aware of the professional incapacity of his em- ployee, where employment is given, no implied liability is entailed but only such liability as will result from actual warrantee. The employment of a professional man does not imply perfection in his work, or the safety or durability of his designs or construction, unless it is proved that unsatisfactory results are due to lack of ordi- nary skill, care or attention. The acceptance of employment by a pro- fessional man does not imply or warrant satisfactory results, but fail- ure due to his direct fault or neglect will render him liable for damage. The duty of the professional man is a duty of reasonable care and dili- gence in the performance of his work. "There is no implied promise that miscalculations may not occur. An error of judgment is not nec- essary evidence of a want of skill or care, and miscalculations are inci- dent to all the business of life."^ He is responsible for the conse- quences of miscalculations and errors only when it is shown that such miscalculations and such errors could have occurred through lack of reasonable knowledge, skill and diligence; and such knowledge, skill and diligence must be such as would be possessed and exercised by a reasonably prudent man in the same profession. Thus'^ an engineer or architect who designs a foundation improperly because he has neg- ligently failed to advise himself as to the character of the soil,^ or who carelessly provides boiler flues in excess of the capacity of the chim- ney^ is liable for the resulting loss. The liability of the professional man is determined by the nature of his contract for employment. This is seldom in formal written form but is usually the result of correspondence or verbal agreement, and often is not definable with any degree of certainty. If, however, he accepts employment with an actual or an implied agreement as to certain definite results, those results must be reasonably approximated or he cannot recover for his labor and may be held liable for any dam- ages that occur. If for example an architect is employed to design a building to cost a specified sum, and the plans when finished cannot be carried out without an expense which greatly exceeds that sum, the 6 Coombs V.

Professional Employment 129 architect cannot collect for his services ; and if the work of construction is undertaken before the fact of excess cost is determined and the speci- fied cost is greatly exceeded, the architect may be liable for such dam- ages to his client.*'^ A small difference is immaterial, but the specified sum must be reasonably approximate; but if the client after finding out that the cost will be increased, decides to use the plans, he must pay for them. § 86. The Engineer as an Agent. — Where an engineer or architect undertakes to supervise the construction of work, he becomes an agent of his client with the authority and subject to the liability of agents. The authority of an agent ^^ unless otherwise known or limited, consists of : 1. Those powers directly conferred. 2. Incidental powers reasonably necessary to carry into effect the powers directly conferred. 3. Powers which custom and usage have added to the powers di- rectly conferred. 4. Such other powers as the principal has by act, neglect, omission or acquiescence caused or permitted those dealing with the agent to reasonably believe he has conferred. 5. Powers exercised by the agent and subsequently conferred by the principal. The duties of an agent are laid down by Spencer ^- as follows : 1. To act with scrupulous good faith toward the principal. 2. To account fully and properly for all proceeds, profits and dis- bursements of the agency. 3. To exercise due care, diligence and prudence in the management of the principal's affairs. 4. To obey all lawful instructions. 5. To notify the principal of all essential matters affecting the agency. 6. To act in person except where authority to act through another •s expressed or implied. The engineer or architect cannot legally act as agent for two parties having adverse interests. The extent of the powers of the engineer or architect should always be defined in the contract. When this is not done, such authority will be determined by the character of the construction and the objects in- 10 Edward Barron Estate Co. vs. Woodruff Co. 163 Cal. 5G1, 126 Pac. 351. 11 Contracts in Engineering. J. I. Tucker, Sec. 146. 12 See Manual of Commercial Law. E. W. Spencer, Sec. 578. 130 Legal Relations tended to be accomplished. Authority to adopt reasonable and proper means to carry the contract into effect will be inferred. The engineer has no other authority in the supervision of work than that which can reasonably be inferred from the nature of the work, or that which is specifically provided in the contract. Inferred au- thority is open to dispute so that it is always desirable that the details of the authority to be delegated to the engineer should be specifically provided in the contract. In the absence of special piovision therefore, the engineer or architect cannot delegate his authority to another. In the matter of positions of special trust and confidence in the professional knowledge, skill and judgment of the employee, the client has the right to select his own agent and might not be satisfied with the selection of another. The engineer or architect is liable for the acts of his assistants when he employs such assistants on his own account to assist him in his undertaking, but not when such assistants are employed by his client even though he select them on behalf of his client and they are subject to his own direction and control. The engineer or architect is presumed to know the extent of his own power and if he exceeds his authority and work is done under his direction for which he has no authority, he makes himself personally liable. § 87. The Engineer as Arbiter. — It is common in construction contracts to confer upon the engineer or architect arbitrary powers to reject or condemn work or material which in his judgment is faulty, and in some cases to require certain expenditures for inspection, pro- tection or safety of the work, if in his judgment they are necessary but which may be burdensome and unfair if not administered in an impar- tial and judicial spirit. These powers have been sustained by the court when exercised in apparent good faith. Against this arbitrary power the contractor has no redress unless corruption can be shown. In a Canadian case of this kind the court said : "I have always thought the position of an arbitrator a most absurd one. He has powers given him that are given to no other being in the world, and it results in hard feeling and litigation ; but the parties if they choose to enter into such a contract must abide by it, having put him in position of sole arbitrator they have to show, if they want to hold him liable, not that he has exercised a very poor judgment but that he is unskilled, that he has been dishonest and fraudulent.^^ 13 Bagley v. Dickson, 13 Ont. »App. 484; also Wait, Sec. 848. Engineer as Arbiter 131 As lack of good faith or corruption is often hard to demonstrate to the satisfaction of a court or jury, the contractor may be unfairly used and put to much unnecessary expense through the ignorance, injustice or even the malicious decision of the engineer. It is evident therefore that, when by the terms of a contract an en- gineer or architect is clothed v^ith discretionary or quasi-judicial power and exercises that power in good faith, he cannot be held responsible for his acts or findings. Such conditions obtain when he acts as ar- biter or referee in the determination of disputed questions or of matters of fact which appertain to the completion of work or the basis of pay- ment, for the same. The same principles hold in the exercise of discretionary power by a public officer ; in general such officers are not liable to private individ- uals for injuries resulting from their act or neglect or for the acts or neg- lect of their subordinates. The public official being elected or appointed can not be held on an implied agreement to exercise the requisite skill, diligence and judgment for his work. § 88. Ow^nership of Plans, Designs and Inventions. — Unless otherwise specifically agreed, the plans for a structure will belong to the owner when he has paid the engineer or architect a reasonable price for his services, at least during the tirrie and for the purpose of construc- tion. Whether or not the designer can require a return of the plans after their use, even when such is shown to be the universal local cus- tom, has not been clearly settled. The unauthorized use of such plans by copying or building from them is held illegal, unless they are published to the world, in which case, unless copyrighted, they become public property. The plans, designs and inventions of an employe are the prop- erty of the employer only if such ownership is agreed or reasonably im- plied. Where a professional designer is employed for the purpose of de- sign he has no rights in the design produced during his employment, but the rights of discovery of a new method of construction or of a new process or material, would remain in the employee, although the em- ployer might retain a license to use them if the discovery was in the direct line of eflfort for which the designer was employed. The results of the work of the designer outside of office hours are however his per- sonal property. In general, the same principles apply to inventions. THE ENGINEER IN LEGAL PROCEEDINGS § 8q. Necessity of Expert Service. — In litigation involving technical matters it is commonly necessary for the parties involved to 132 Legal Relations call in engineers who are specially informed on the matter in question. This is made necessary by the fact that the attorneys employed, while possibly learned in the law affecting the case at issue, cannot be in- formed on the many and diverse technical matters which they are called upon to present to the courts. It is highly desirable that the at- torneys employed on any technical case should have had previous ex- perience on similar cases, as such experience will greatly facilitate the preparation of the case and assure its more adequate presentation. In any event technical litigation will ordinarily require expert serv- ice for the purpose of : First: Consultation in regard to the technical details involved. Second: Assistance in the preparation of the case. Third: Assistance in the examination of technical witnesses by the attorney. Fourth: As expert witness. § go. Consultation. — In most cases w^here litigation arises concerning technical projects or affairs, there are certain questions in- volved which are more or less doubtful. These questions must be de- termined by evidence concerning the facts in the case, and often by the opinions of men experienced in the particular subject as to the bearing of the facts on the points at issue. It is therefore evident that before litigation is begun, all such facts and the logical conclusions to be drawn from the same should be determined by those who are qualified by learning and experience to judge as to their significance and as to the correctness of the claim which it is proposed to support by legal action. When the engineer is called in on such matters he should, before he expresses an opinion in regard to the point at issue, determine all of the facts in the case and all of the conditions which surround it and, after careful deliberation and study, deduce the logical conclusions which naturally follow such facts and conditions. Opinions based on an ex parte statement of the matter are often quite misleading and should be studiously avoided and before his final conclusions upon any important questions are rendered he should insist upon the oppor- tunity of a thorough investigation and a careful consideration of all of the facts and data, and upon a careful examination of the best authorities available. Perhaps the suit itself or at least the results of the suit may depend upon the truth of the opinions he expresses, and in the course of the litigation, if such litigation is undertaken, it is more than likely that any opinion and conclusion which he has expressed will be subject to scrutiny of others equally well informed who will be called on by the other side of the litigation and whose equal duty it becomes Consultation 133 to see that the rights of their clients are fully preserved and that justice prevails. It is obvious that no conscientious professional man will knowingly accept employment which involves an attempt to subvert justice and permit wrong to triumph. It is however frequently the case that tech- nical questions are so involved that there are facts and conditions which seem fairly to warrant the justice of the claims made by both parties to the litigation. It is the undoubted right of each to present disputed claims in the light most favorable to themselves so long as the truth is not perverted and justice is the ultimate aim. For this reason, unless it is evident that the purpose of the client is unfair or dishonest or that his claims are founded on a perversion of facts or incorrect conclusions, there is no reason why he shouM not be fully entitled to professional aid to the extent that the ends of justice and equity require. Unfortunately the desire of the client is not always limited to the above ends. Frequently he desires to win his case regardless of law or of equity, and he is not always scrupulous as to the methods employed provided the desired ends are consummated. Not only is this the case, but it is frequently true that personal bias of the client, his attorney and engineers is so developed by their personal interests and their associa- tion with the question involved that they are unable to discriminate as to the justice of the case or as to the logical conclusions to be drawn from the facts and conditions. Such bias is but human and may be justly condoned so long as it does not lead to an attempt at fraud or de- ceit. When carried so far as to create the belief that victory is so de- sirable that the end will justify any means, it reaches beyond the pale of honorable practice, and employment in such case must be avoided by all conscientious men. § 91. Preparation of the Case. — Having convinced himself of the truth and justice of his client's contention, the engineer may be of great value in the preparation of the case for its presentation in court. In this work the engineer must not only fully inform himself in regard to all facts and conditions affecting the case but he must collect all in- formation and data and arrange and classify the same in such form as will best serve the purposes of presenting the matter to expert witnesses for their examination and for their use in forming their opinions and preparing their evidence, and of presenting the facts to the court dur- ing the progress of the case. The engineer's work will consist of securing and arranging the facts and data pertinent to the case and in devising means and methods by which the facts and principles involved may be so simplified, clari- fied and presented as to make the conclusions as nearly obvious as pos- 134 Legal Relations sible to the minds of the court or of the jury. Frequently the matter involved may be complicated or of such a distinct and technical nature that it will not be easily understood by those unfamiHar with it or those who are not technically informed. It is often exceedingly difficult to simplify scientific or technical principles so that they may be compre- hended by the non-technical and that the logical conclusions may be seen and appreciated. To accomplish this will require all of the in- genuity, ability and knowledge of the professional man. He must en- deavor to understand the normal point of view of the judge or jury and to arrange the matter and the material so that they, with their limited knowledge and experience in such matters, may be able to grasp the facts and deduce conclusions after the presentation of the technical or scientific principles by the expert witness. In this connection and prior to the presentation of the case in court, the engineer has first to present these matters in a similar way to the attorney for his client. Here he has an auditor whose normal bias gives him the inclination to accept conclusions favorable to the client but who must normally be shown the logic of the conclusions and be convinced that the facts, conditions and principles as laid out by the en- gineer are capable of proof and are a proper and scientific method of presenting the case. The engineer must clearly inform the counsel as to the principles involved so that he may properly appreciate the ways and means by which the matter may best be presented. The very need of the engineer in the preparation of the case is due to the fact that the attorneys in the case are working in a field more or less foreign to their common practice and in which, while generally informed, they are ig- norant of the details and principles which apply to its more technical aspects. The engineer and counsel must work in unison, for the en- gineer on his part is normally ignorant of the detailed methods of court procedure, so that the preparation of the case must be carried on by fre- quent interviews and discussions in order that, by the combined effort of the attorney and engineer, the matter may be presented in the best possible manner. The engineer may also be of great aid in the selection of expert witnesses whom he knows to be trustworthy, capable, throughly in- formed on the matter involved, and able to present their ideas and opinions in court in such a manner that the judge or jury may be im- pressed by their learning, ability and honest intentions and understand and appreciate the conclusions which he endeavors to elucidate. An engineer may also greatly assist the attorney in forecasting, so far as practicable, the probable line of expert testimony which will be Technical Witness 135 oliered by the opposite side and by arranging for witnesses qualified to meet it. In general, the attorneys must rely entirely upon their tech- nical adviser in such matters. § 92. Examination of Technical Witnesses. — An engineer who has thoroughly studied the subject and fully appreciates the principles involved and the essential ideas which it is desirable to develop in order to properly present the matter to judge or jury, can be of great value as an adviser both in the direct and in cross examination. On prin- ciples that are well established, the same answer will undoubtedly be given by the expert witness of either party. On questions depending on opinion such answers may differ largely. No matter how honest the expert witness may be, he is not allowed to volunteer information and can give an answer only when a proper question is propounded. It is practically impossible for one unfamiliar with the technical matter at issue to frame questions so that they will necessarily involve the an- swer sought, and many technical cases have been lost by the inability of the attorneys to understand and bring out the facts and principles at issue (see Sec. 51) even from their own witnesses. The difficulty is accentuated in the case of cross examination where the opposing wit- ness, who is often more or less antagonistic, must be made to give the answer desired by a carefully framed question which will admit of no alternative. Technical cases have been won purely on cross examina- tion of opposing witnesses by attorneys well versed in the subject under litigation and advised by competent experts. § 93. The Expert Witness. — The selection of an engineer, ex- pert in his specialty, is a matter of great difficulty (see Sec. iii) ; but the selection of an expert witness is even more difficult, for a man may be thoroughly informed in his specialty, competent to design and con- struct and yet may be unsuitable to present his ideas and opinions in court in such a manner that the judge or jury will understand the tech- nical principles involved and the conclusions which logically follow from the facts and conditions. "Unfortunately the average technical man cannot explain his work so a layman can understand it ; the average engineer has this fault in an unusual degree, and the successful presentation of his testimony may be a matter of considerable training, in order that he will drop his tech- nicalities and details and stick solely to the essentials of the case. If he will tell his story for his own side so that it can be understood, his in- ability to explain himself clearly under the cross-examination of the opposing counsel may be safely left to work itself out." (Eng. Rec. Vol. 60, p. 141.) 136 Legal Relations "There is nothing unprofessional in the initial presumption of an engineer that a prospective client's interest justifies professional defence, or in exerting his best efforts in making that defence even though there may be more or less doubt involved. In fact, that doubt is just what should be turned into a certainty in favor of the client if possible. If on the other hand, it is clear that the technical position taken by the client is indefensible as an engineering proposition, any engineer would be recreant to his professional principles if he did not plainly and un- qualifiedly advise that client of the erroneous position assumed by him. This is by no means an uncommon experience. There probably are few engineers who have had much consultation experience who could not name a considerable number of cases where the only true professional course has been to advise an emphatic negative to propositions where an encouraging affirmative was confidently expected. There is, however, no evading this kind of responsibility. As a professional man he is bound by the highest professional obligation to place his best judgment and knowledge at the service of those who seek him, whether the result favors the contemplated project or not. It is as much his duty to tell a client that he is wrong, if he is wrong, as to tell him he is right when he is right." (Eng. Rec. Vol. 57, p. 737.) Not only are the parties to litigation frequently wrong in their views of the rights and principles involved, but too often a deliberate attempt is made to bolster up an unjust case by biased evidence. "One of the leading American constructing engineers was asked to serve as an expert witness in an important suit. He had the usual aver- sion to such work, but the prominence of the parties asking him to serve was so great that he did not care to decline outright. He accordingly named an excessive fee and expected the matter to drop there. To his astonishment the fee was immediately approved and the lawyers vis- ited him to explain the case and state just what he was expected to tes- tify. He protested that the tesimony would be seriously incorrect technically, but he was then informed that such things were really mat- ters of judgment and the very large fee he was to receive was for the purpose of showing to the court that the desired opinions were held by an eminent engineer. If he changed his views after the case was set- tled it would be a matter of indifference to the lawyers and their clients. It is hardly necessary to say that the engineer did not see the matter in the same light." (Eng. Rec. Vol. 62, p. 533.) It is said that in the early courts of Rome there were certain indi- viduals who wore straw in their shoes; this was to signifv that they were prepared to go into court and swear to whatever conditions their clients might desire. There are very few such men in the ranks of the The Expert Witness 137 gineering profession, and those who do appear soon sink into the obliv- ion they so justly merit. No man in any profession who blinds his con- science in favor of unrighteousness can hope to attain that respect and eminence which should be the object and desire of every man. In numerous legal proceedings of the same class, it is common to find certain individuals uniformly representing one aspect of the same question. For example in the condemnation of public utilities, certain experts if employed are uniformly employed on the part of municipali- ties while certain others are as uniformly employed only on the side of utilities. This is due not necessarily to dishonesty but to a certain bias of the individual judgment that makes his testimony of greatest value to the side which he commonly represents. This bias may be more or less radical and is often the result of peculiar experience or a one sided point of view, and in many cases the opinions of such parties would be radically changed if they were called upon to carefully consider the subject from a different aspect. It may be added that whenever an honest and conscientious en- gineer finds himself repeatedly called to sustain a certain definite point of view in a variety of similar cases, he will do well to carefully analyze his position and examine the basis of his opinions and determine whether his conclusions are not being radically affected by the limita- tions of his experience and affiliations rather than by any profound knowledge of the subject. § 94. Qualifications. — In order to be competent as an expert, the witness must show that he possesses knowledge or skill in the mat- ter on which his evidence is desired. His qualifications may depend on observation, experience or study. The extent and nature of the prac- tice and experience which can be shown to qualify him particularly for a proper judgment of the matter at issue will often greatly affect his value as a witness. His qualifications are usually demonstrated by an examination preliminary to his admission as a witness, in which he is given opportunity to explain his knowledge and experience, his oppor- tunities for observation and investigation, and such other facts as may demonstrate his fitness. His admission as a witness is largely within the discretion of the court. § 95. Expert Evidence. — In general the opinions of witnesses are inadmissible as evidence and are considered irrelevant. The excep- tions to this rule are in those cases where the opinions of experts are re- ceived, and such cases are confined to subjects beyond the knowledge of men of ordinary education and experience. 138 Legal Relations In many cases where the subjects of litigation are wholly unfa- miliar to the judge or jury, the admission of expert testimony is the only adequate method of arriving at substantial justice. Nevertheless such evidence is often justly considered of little credence or value. "The evidence of experts is of the very lowest order and the most unsatisfactory character."^* "It is the inherent infirmity of expert testimony that it consists largely of matters of opinion in add'.tion to those elements of weakness and uncertainties which enter into the testimony of those who relate simply what they have seen or heard. We have, in expert testimony, the deductions and reasoning of the witnesses with all the chances of error incident to human reasoning. The notorious fact that experts of equal credibility and skill are found in almost every important case, testifying to directly opposite conclusions, illustrates both the fallibility of such testimony and the fact that a conviction for perjury based upon such evidence would be very difficult. It is a matter of common ob- servation in the courts that witnesses of the highest character and of undoubted veracity may be easily lead as experts to espouse and de- fend a theory with all the zeal of the advocate. "^^ "Lord Campbell, in the case of the Tracy Peerage (lo C. & F., 154, 191), placed on record his judgment of the worthlessness of the system which would fain evoke a judicial answer or opinion from a human be- ing whose preparation for thus thinking and speaking had been a life of weeks or months, may be in the environment which ordinarily falls to the lot of the advocate ; not to speak of the futility of expecting to get such an opinion from a man placed in the witness stand, and con- demned to say naught but in answer to ingeniously concocted, perhaps more or less rasping questions. "I do not mean," said Lord Campbell, "to throw any reflection on Sir Frederick Madden. I dare say he is a very respectable gentleman, and did not mean to give any evidence that was untrue ; but really this confirms the opinion I have entertained, that hardly any weight is to be given to the evidence of what are called scientific witnesses ; they come with a bias on their minds to support the cause in which they are embarked ; and it appears to me that Sir Fred- erick Madden, if he had been a witness in a case, and had been asked on a different occasion what he thought of this handwriting, would have given a totally different answer."^^ i4Whittaker v. Parlcer, 42 Iowa 586. 15 Jones on Evidence, 2d Ed. Sec. 390, 16 On the Best Manner of Making Use of the Services of Experts in the Conduct of Judicial Inquiries, by Clemens Herschel. Eng. News, Apr. 9, 1887, p. 234, Expert Evidence 139 Much that is similar to the above has been said from the bench and by writers on Evidence in criticism of expert testimony and some radi- cal change is undoubtedly desirable in judicial procedure in order that such testimony may be utilized to conserve the ends of justice. It is too much to expect however that this will ever be accomplished so long as the courts must depend either upon the presentation of evidence by experts employed by the opposing parties in the case who from the na- ture of the judicial procedure are more or less biased in favor of their client, and are not permitted, even if they so desire, to express their competent and unbiased opinion on the subject. The questions asked are so framed as to command the answers given, and the nature of the cross examination is usually an endeavor to confuse the witness, be- little his ability, prove the falsity of his opinion and as a result arouse the antagonism which is detrimental to the ends of justice. Expert witnesses are but human and humanity is not infallible even when clothed in the garments of the court. Our highest tribunals are closely divided on judicial opinions, and many cases are decided by bare majorities, showing that entirely disinterested and fair minded judges are not able to arrive at unanimous decisions. In other cases judicial decisions have been rendered by jurists whose interests or con- nections have been such as to bias their judgment so that their impeach- ment resulted as a consequence of glaringly erroneous decisions. Even the supreme court of the United States decided the Tilden-Hayes Pres- idential controversy on purely political lines, and numerous cases might be cited both of the supreme court and of lower courts where the de- cisions have resulted from pure bias. The fact that such bias may and sometimes does exist, is recognized by the provisions of the law which permits attorneys on a presentation of a sworn statement of prejudice to seek another jurisdiction for the trial of their case. In a recent case in one of our states, in which a very important public question had aroused considerable public controversy, a special court made up of seven judges, after hearing extended evidence on the subject, decided the matter on purely political lines. There was not one of the judges acting in the case but that, on the final ballot, voted from the point of view which was most popular in the district which he represented. It is evident that in the nature of cases requiring expert testimony, such testimony will be arranged beforehand and that neither side will call witnesses whose testimony will be detrimental to their interests. It is obvious that under these circumstances the expert witness has al- ready expressed his opinion on the subject and that such opinion is favorable to his client. In many cases this opinion has been due not 140 Legal Relations only to a careful consideratxon of the facts and data available but to a long and exhaustive examination and consideration from the point of view of the client. Under such circumstances it is certain that the ex- pert will be interested on his client's side of the case and will ordinarily desire its success. He is moreover under certain obligations for em- ployment by his client and under such circumstances his judgment can- not be altogether unbiased. While this condition has its objectionable features, it is equally true that it is not without its advantages. This partisanship is not without its use in the ultimate triumph of equity and justice, for it leads to a most careful scrutiny of the case in an endeavor to bring out all of the points which tend to demonstrate the justice of his client's claim, and it is doubtful if this could be accomplished by the un- biased investigation of an entirely disinterested expert. "The thoughtless observer of a trial is likely to draw the impression that the representatives of each side are monumental liars, but this opin- ion is generally entirely wrong for three reasons, one being that most witnesses testify merely from memory without the help of a diary, an- other being that the lawyers often succeed in preventing a witness from telling the whole truth, and the third being that where the divergence of views between two parties was a matter of slow development and the case was a long time in coming to trial, the recollections of the various parties must inevitably be tinged by their own interests and not those of their opponents. The court and jury are consequently obliged to take this mass of conflicting evidence and ascertain as far as possible by the preponderance of creditable testimony on which side justice probably lies, or whether both parties are not partly wrong and partly right, which last condition is almost always the case. If the dispute involves technical features it is evident that greater complexity is introduced, because here conditions which are not within the knowledge of most men must be thoroughly understood before a case can be equitably de- cided." — Eng. Rec. Vol. 60, p. 141. § 96. Desirable Reform of Procedure. — From the previous con- sideration of the matter, it is evident that the present status of expert testimony must be regarded as largely normal and nothing more than what should reasonably be expected. It is only the part of wisdom therefore that the procedure in such cases should be corrected along the lines which will utilize the beneficial results of the present system of in- troducing expert evidence and offset its disadvantages by the use of the expert or board of experts as the adviser of the court. It is not desirable that the present system be entirely dispensed with or that the freedom of the parties to present any competent testi- Expert Evidence 141 mony be abridged. It has occasionally been advocated that no experts should be heard except those appointed by the court, but it is a fact be- yond question that the courts are not as a rule competent, in this day of narrow specialties, to select experts adequate to bring out properly all of the points at issue, and are otherwise so subject to human weaknesses that such appointments would not be beyond the pale of personal and political influence. In the judicial procedure of cases of expert evidence, what is needed at the present time is not that the expert should be chosen by the court but that the court should have expert advisers who are able to weigh properly the testimony submitted and to differentiate on the basis of their scientific or technical knowledge of the subject the true from the false, the essential and the non-essential, and to draw correct conclusions from the mass of evidence which is frequently beyond the capacity of the presiding judge or of the jury. § 97. Appraisal of Public Utilities. — In the appraisal of public utilities, the same difficulties are encountered as in other procedures for the determination of technical matters by expert testimony. Before the appointment of state public utility commissions, it was the general practice, usually as specifically provided in the franchises, to appoint a board of three or five appraisers for the purpose of determining the values of the properties. In some cases the acceptance of the findings was optional and in other cases obligatory. In the majority of such cases engineers were appointed for this purpose. Each party to the proceeding appointed one or two, and those so appointed elected a third or fifth person as chairman. In these cases almost without exception the experts appointed by each party exhibited more or less of the bias due to such appointment (see Sec. 12) and with few exceptions acted as advocates for the client to whom their appointment was due. The third or fifth member being independent of either party in his appoint- ment, fulfilled the function of judge or umpire and adjudicated the dif- ferences of opinion and ultimately the findings of the board. In the majority of cases the members of such boards undoubtedly endeavored to overcome their bias and to render substantial justice, but the effect of their appointment was almost universally apparent. In the few cases where such commissions were entirely free from this ex parte character, the differences were immediately apparent and the results were far more satisfactory. There is no doubt that the appointment of State Public Utility Commissions for the fixing of values and rates is in principle a move in the right direction. The main difficulty has been that in many cases such appointments have been more or less political and such boards 142 Legal Relations have usually been constituted of judges, lawyers, economists and statis- ticians of greater or less ability but with no particular aptitude for the work in question. Some commissioners, while nominally unbiased, have in fact felt that they held a brief for the people and were appointed to see that the rights of the people were safeguarded and preserved. This bias has often resulted in findings which were unjust and inequitable. Where however they have continued long in office, they have usually gained a good insight into their real duties and the justice and equity of their findings have greatly improved. It has been unfortunate that such boards have not been uniformly constituted with at least one technical member who possessed real practical experience in the construction and administration of such properties. In most cases these commis- sions have employed a corps of technical advisers, but in general from lack of funds or of an appreciation of the requirements of the cases, they have secured young professional men of little experience or special technical knowledge, with results which would naturally be expected from estimates and findings based simply on theory. Even where technical aid has been employed, it has not been uti- lized in such a manner as to secure the best results. Usually estimates have been prepared by the corps of the board and submitted to both parties prior to the hearing. At the hearing ex parte expert evidence has been heard by means of which attempts have been made either to reduce or increase certain items of the estimates which it was considered desirable to contest. Those items which were satisfactory because actually too high or too low were not contested. The corps of the board having once filed their values are only more firmly convinced by the attack of both parties of the justice of their findings, and are driven to correction only when their position is shown to be untenable. Every consideration of the nature of expert evidence and of hu- man nature would logically require that all evidence by the expert wit- ness of the two parties to the case first be presented after which the evidence should be considered, investigation made, and a finding reached by the experts of the commission. This arrangement would undoubtedly result in more just and equitable findings than under the conditions now widely extant. § 98. Professional Duty. — The true aim of the profession of en- gineering is the establishment of truth. If the engineer, by his special knowledge, can assist in the establishment of justice he has a duty to perform that cannot be laid lightly aside. "If he is true to his profession, he will always give the results of his study, whether it bears for or against the side upon which he hap- Literature 143 pens to be called. If he is not prepared to do that, or if the circum- stances of the case prevent it, then he is in duty bound to decline, or re- fuse to render his services. Th:s he may not always do; but if com- pelled to attend against his wishes, he cannot be said to be under any ob^-igations to either party to the suit, and may exercise his honest judg- ment, without prejudice or criticism. "^^ In accepting service as an expert witness, the engineer owes it to himself, to the public and to his profession to restrain his personal bias, retain his high ideals, and to lend his services only to the support of truth and justice. "The Golden Rule applies in expert testimony as every where else. Translated for this occasion this might say 'Do not make statements in giving testimony which vou would not be willing to support before any gathering of engineers.'

Contracts are the outgrowth of the daily association of individuals in a business capacity. If A agrees to do some lawful act for B in ex- change for a valuable return from B, whether services or other thing of value, both parties being competent to contract, A is under a legal obligation to B. This agreement between A and B is a contract. It should be understood from the beginning that contracts are not, as might at first appear, formal legal documents in writing filled with legal phraseology and entered into with a great deal of solemnity, for there are thousands of contracts executed every day where there is not a line of writing, a scrap of paper or anything but the spoken word or implication of action to evidence the contract. A calls his grocer B by phone and orders a dozen eggs. B delivers them to A's house ; A has then entered into a contract with his grocer, B. B has delivered the eggs to A and A by imputation of law is bound to pay B a reasonable price for such eggs. Practically every business deal is a contract and whenever money or other things of value are exchanged for some article of everyday need, such as a pencil, a bar of soap or anything of the kind, a contract is entered into and executed by the person purchasing and with the person from whom such articles are purchased. Contracts therefore are not the result of solemn and complicated legal documents but are common every day affairs. DEFINITION OF CONTRACTS "A contract is an agreement enforceable at law between two or more persons, by which rights are acquired by one or more to acts or for- bearances on the part of the other or others."^ Blackstone has defined a contract as "every agreement between two or more parties for the doing or not doing of some particular thing." § 100. Classification of Contracts. I. Contracts may be executory, that is where an obligation is as- sumed by one or both parties to do or to forbear from doing some acts ; 1 Clark on Contracts, 3d Edition, page 2. 146 Elements of Contracts or they may be executed, that is where everything is done at the time of the agreement and no obHgation is assumed. Example of Executory Contract. — A agrees to deliver one ton of coal to B upon the promise to pay A $8.00 therefor. Example of Executed Contract. — A delivers a ton of coal to B and B pays him $8.00 therefor. It will be seen from the above example that an executory contract when fully performed becomes an executed contract. 2. Contracts are also classified as bilateral and unilateral. Willis, on contracts, defines such contracts as follows : "A bilateral contract is an executory contract consisting of an ex- press promise of one legal right, and the counter promise of another legal right given in exchange therefor." "A unilateral contract is a half executed, half executory contract, con- sisting of an express or inferred promise of one legal right for another legal right." Example of Unilateral Contract. — A advertises that he will pay a given price per pound for all old magazines and paper delivered to him at a given place. B, acting on the advertisement, delivers to A at the place stated one thousand pounds of old magazines and newspapers and becomes entitled to payment therefor at the advertised price. Example of a Bilateral Contract. — A know^ing that B has one thousand pounds of old magazines and newspapers writes to B and offers him four cents a pound for these old magazines and newspapers, and B writes a letter in reply accepting the offer of four cents a pound for one thousand pounds of newspapers f. o. b. Madison. A wires stating that the terms are accepted f. o. b Madison. This constitutes a bilateral contract. 3. Contracts are further divided into express, implied and quasi con- tracts. An express contract is a bilateral contract all of whose terms are as- sented to either in speech or writing. An implied contract, or an inferred contract as they are sometimes called, is a unilateral contract where either the act of acceptance or both the act of acceptance and the promise are inferred as a matter of fact from conduct. A quasi contract is not a contract but a legal obligation like a con- tract, created by implication of law. Quasi contracts are implied by law on the theory that it would be unjust to allow one to accept the benefit of labor or anything of value which belonged to another without refunding it or paying him for his services. If one acting under the mistaken impression that a debt is his own pays it, and it afterwards develops that it was the debt of another, the law implies a promise on the part of the other to repay the money so paid out. Classification of Contracts 147 Example of Implied Contract —K offers a reward for information leading to the arrest and conviction of the person who set fire to his barn, and B makes an investigation and furnishes the information to A, which leads to the arrest and conviction of C for the crime. The acceptance of the terms of the offer are implied by the conduct of B and he becomes entitled to the reward offered. Example of Quasi Contract. — A, an engineer acting under the mistaken im- pression that B called him by phone and requested that he design a drainage system for his farm, when in fact it was C that called him, goes to the farm of B without the "knowledge of B and makes a survey and designs a system, plans of which he mails to B. C, who contemplated the drainage of his farm, used the system designed by A. There has been no actual contract between A and C, but A, expecting to be paid has done work of value for C, but with- out C's knowledge, but later C accepts the benefits of A's work and the law creates the contract and A may recover the value of his work from C just the same as though there had been an express contract for the work. 4. Contracts are further classified as joint, several, and joint and several. "A joint contract is one in which the promisors are jointly bound, or the promisees are jointly entitled to the performance of a legal obliga- tion."2 "A several contract in one in which either each promisor is individ- ually liable, or each promisee is individually entitled, to the perform- ance of /a legal obligation."- "A joint and several contract is one in which the promisees may elect to hold the promisors either jointly or severally, bound to perform a legal obligation."- In determining whether a contract is joint or several, the courts will determine the intention of the parties, and wherever possible, will con- strue it as joint or several as to the promisees, according as their inter- ests are joint or several. If the promise is by two or more, and is in the plural number, it will be deemed to be joint, and if in the singular it will be deemed to be several, unless the entire agreement shows a different intention. A subscription agreement, even though joint in form, will be con- strued as a several contract. Example of Joint Contract. — A and B sign the following note: "Six months after date we promise to pay X and Y, for value received, five hundred dollars, with interest at 6% per annum." A and B are jointly liable for the payment of the money and X and Y are jointly entitled to have the money paid to them. Example of Several Contract. — A and B sign the following note: "Six months after date, for value received, I promise to pay X and Y, to be divided equally between them, five hundred dollars with interest at six per cent per -'Willis on Contracts, Sec. 177. 148 Elements of Contracts annum." A and B are each individually liable to X and to Y, and both X and Y are individually entitled to performance, each being entitled to the payment of $250 and interest on that amount. Example of Joint and Several Contract. — A and B sign the following note: "Six months after date for value received, we, and each of us, promise to pay to X five hundred dollars with interest thereon at the rate of six per cent, per annum." X is entitled to enforce this note against A and B jointly or to collect from either of them individually the full amount of the note with in- terest. 5. Contracts are still further classified as valid, voidable, void and unenforceable. A voidable contract is one where one party to the agreement is not bound by it and may, at his option, avoid the contract. A void contract is one which creates no legal obligation. An unenforceable contract is one which is incapable of performance but is otherwise valid. It is sometimes called a contract of imperfect obligation. All contracts which do not come within the terms of the above defini- tions are valid contracts and are binding on both parties to the contract and may be enforced by law. Example. — A and B enter into a contract whereby A agrees to perform certain services for B for $10. If both parties are legally capable of contract- ing they have entered into a valid contract. If B is a minor, the above contract is a voidable contract as B, at his option, may refuse to carry out his part of the contract. If they contract to do some unlawful act, such as running a gambling game, the contract is void and creates no legal obligations whatever. Valid contracts, on which the statutes of limitations have run, cannot be enforced by suit and are therefore unenforceable contracts. 6. Another classification that should be noted is that of parol con- tracts, which may be oral or written, and specialties, which must always be written. An oral contract is an express contract without other evidence than the spoken word. A written contract is an express contract evidenced by writing. A specialty is an express written contract under seal, that is a writ- ten contract to which the parties attached their seals, or to which they write after their signature the word (seal). It differs in no other way from an express executory contract. The seal being attached to the contract, raises the presumption that the agreement was executed with so much solemnity and deliberation, that it was founded on a sufficient consideration and therefore renders proof of consideration unnecessary. Under the common law certain classes of contracts were required to Essentials of Contracts 149 be executed under seal. In many states in the United States the com- mon law has been adopted or slightly modified by statutes and requires that certain classes of contracts shall be executed under seal. For ex- ample, deeds, mortgages and bonds shall be under seal. Parol contracts are contracts not under seal, whether written or oral. § loi. Essentials of a Modern Contract. Not every agreement between two or more parties is a contract, and in order to constitute a binding contract it is necessary that the agree- ment conform to certain legal requirements which are based on the com- mon law and a vast number of decisions in England and the states of the United States. The essential elements of a contract are briefly as follows : (i) There must be two or more contracting parties who are com- petent to enter into a contract. (2) There must be a mutual consent of the parties contracting, to the terms of the agreement. That is, there must be a meeting of minds of the parties to the contract. (3) There must be valuable consideration for the contract. That is, something of value must be given in exchange for its legal equivalent. (4) The subject matter of the contract must be lawful. (5) Whenever it is required by the statutes of frauds, there must be a writing. § 102. Competency of Contracting Parties. Every contract must have two or more parties who are legally com- petent to enter into the contractual relations, for a man cannot enter into a contract with himself which will be enforceable at law. The following persons are, under certain circumstances, incapable of enter- ing into a valid contract : (i) Minors. (2) Persons of unsound mind. (3) Drunken persons. (4) Persons under legal guardianship. (5) Corporations, under certain circumstances. (i) Minors. By the word "minor" is meant any person under the age of twenty-one years. Minors are sometimes referred to as infants. Minors are capable of contracting for necessaries. What are neces- saries for a minor is dependent to some extent on his position in life. The term necessary includes anything which is reasonably needed for his subsistence, health, comfort and education, taking into consideration his age and condition in life. 150 Elements of Contracts The following rules will be helpful : (a) The thing furnished must concern the person of the minor and not his estate. For example, he would not be bound by contracts to construct a building on land which he owns, nor for a subscription to stock in a railroad corporation, etc. (b) He is not liable for money which he borrows to spend for neces- saries unless the person loaning the money sees that it is so expended, because money is not considered as a necessary and one loaning the money must see that it is actually spent for necessaries. (c) He is liable for necessaries furnished his wife, and in some ju- risdictions for his children. (d) Persons supplying a minor act at their peril and cannot recover if the actual circumstances were such that the things furnished were not necessary. A contract entered into by a minor with any other party capable of entering into a contract is not a void contract, but is voidable at the option of the minor. The contract is binding on the adult person but may be avoided by the minor either during his minority or before he has ratified it after attaining majority. Such a contract may be confirmed by the minor after attaining his majority by his express ratification, by acts of his which merely show his intention to confirm the contract, or by his omission to disaffirm the contract within a reasonable time, if such omission is prejudicial to the interest of the other party or within the statutory period of limitation. Example. — A, a minor, entered into a contract with B by which A agreed to purchase a horse of B, and to make monthly payments of five dollars ($5) each, and to take possession of the horse when he had made payment of one- half the amount. If he continued to make payments after he became of age, this would be a confirmation of the contract by his act which would clearly show his intention to carry out the terms of the contract, and his election to be bound by its terms. Or, if having gotten possession of the horse before he attained his majority, he continues to keep the horse in his possession and does not make payment of the unpaid balance of the purchase price, but does not, either by express words or by his acts, show his desire to continue under the terms of the contract, his omission to disaffirm the contract being pre- judicial to the interests of the other party, the law presumes a ratification of the contract on the part of the minor. If a minor avoids a contract on which he has received money or prop- erty, he must restore it if it is in his power to do so. Where a minor has performed services in partial or entire execution of an express contract, and he avoids the contract, he may recover the value of the services rendered in an inferred contract. Competency 151 (2) Persons of Unsound Mind. — A contract entered into by an in- sane person or a person of unsound mind is not a void contract but is voidable at the option of the insane person, or the person of unsound mind, or at the option of his legally appointed guardian, with the fol- lowing exceptions: (a) Contracts created by law are valid and bind- ing, and (b) contracts where the sane person acted fairly and in good faith and without any knowledge, actual or constructive, of the other's insanity if the contract has been carried out to such an extent that he can not be placed in status quo. In most jurisdictions, contracts made by a person who has been le- gally declared insane and placed under guardianship are void. Powers of attorney, appointment of agents and, in some jurisdictions, deeds when made by an insane person are void. As a general rule, contracts entered into by an insane person for necessaries are held to be valid. Contracts made with an insane per- son during an interval when he is sane are held to be binding. Contracts made by an insane person are simply voidable and may be ratified by such insane person when he becomes sane or may be ratified by his guardian during his insanity or by his heirs after his death. (3) Drunken Persons. — Contracts made by a drunken person when in such a state of intoxication as to be entirely unable to understand its nature and effect are voidable in his favor except that he is liable on contracts created or implied by law. If he is in a mild state of intoxi- cation and is capable of understanding, the same contract is valid unless the circumstances surrounding the execution of the contract are such as to raise the inference that it was obtained by fraud. The rules rela- tive to the ratification of a contract entered into by drunken persons are the same as those applying to a person of unsound mind. (4) Persons Under Legal Guardianship. — Persons under legal guard- ianship by reason of feeble mindedness, their being habitually drunkards or spendthrifts, or by reason of idleness or debauchery, are limited in their ability to enter into contracts in a manner similar to minors, per- sons of unsound mind, and drunken persons. (5) Corporations. — A corporation is an artificial person created by law, and is limited in its ability to enter into contracts by its articles of incorporation and by-laws, and general statutes limiting the powers of corporations. A contract with a corporation must be a contract which it is authorized to make and which is within the scope of its corporate powers as set forth in its articles of incorporation. It must be entered into for the corporation by its properly authorized officials, and must have been authorized by its legally governing body, usually a Board of 152 Elements of Contracts Trustees or Board of Directors. A corporation may delegate the au- thority to enter into contracts on its behalf to one or more individuals, usually its president or manager. A corporation may contract for things within the scope of its powers, and things which have been authorized by the legally governing body in the same manner and under the same circumstances as a natural person ; and if the contract is within the powers of the corporation, when it is necessary or reasonably incidental to the purposes for which the cor- poration was created, and is not expressly prohibited, it is binding on the corporation. § 103. Mutual Consent. It is essential to the validity of a contract that the parties thereto agree, and they must agree to the same thing. There must be an act- ual agreement and not simply an apparent agreement. Both parties to the contract must agree to the same thing, and where there is a mistake as to the nature of the transactions, in the absence of negligence on the part of the parties to the contract or to the persons with whom the con- tract is made, or as to the existence or identity of the subject matter of the contract, the parties have not agreed to the same thing and the con- tract is not binding and can be avoided on this ground. It cannot be avoided on the ground that a person was mistaken as to the law of the state for the laws of the state are accessible to every one and. they can ascertain what they are. (i) Offer and Acceptance Identical. — In order to create contractual relations there must be an offer on the part of one of the parties to the contract and an acceptance by the other party thereto. This offer must be accepted without qualification and without change or there is no contract. Example. — If A offered to enter into a contract with B, whereby A was to pay B $500 to design a drainage system for A's farm, the said designs to be completed by March 1, and B accepted this offer with the provision that he would design such drainage system for $600, the same to be completed by April 1, there would be no contract as the terms of A's offer were not accepted as they were given but were modified by B. (2) Time of Acceptance. — The offer must be accepted within a rea- sonable time and where a time limit is fixed in such offer, it must be accepted before such time limit expires. Example. — A wires offering B 1000 bushels of winter wheat at $1.15 a bushel f. o. b. Minneapolis. B waits a week and the price of winter wheat has gone to $1.50 per bushel, and wires an acceptance of the offer. The courts would hold that with a commodity such as wheat which was subject to sud- Mutual Consent 153 den changes in mar"ket price, a week would be an unreasonable time and an acceptance at the end of that time would not constitute a contract. (3) Mode of Acceptance. — If a mode of acceptance is specified in the offer the acceptance must correspond to such mode. If an offer of a contract is made and specifies that the acceptance must be by wire an acceptance in person or by letter does not constitute a contract, and if the offer specifies a place of acceptance, acceptance at any other place is not sufficient. An offer and acceptance may be made by letter or by telegram as well as through any other agency, provided another method of acceptance is not specified in the offer. In other words, it is not necessary that the contract be reduced to a formal contract in legal form in order to have it valid and binding, but a series of letters and telegrams may form just as binding a contract as a written document drawn by a lawyer. Example. — A writes a letter to B on January 18, offering him 10,000 bushels of wheat at $1.15 per bushel f. o. b. Minneapolis. B wires back to A on the 19th of January stating: "Your offer in letter of January 18 accepted. Letter follows." He then writes A the same day accepting his offer of 10,000 bushels of wheat at the specified price. These letters and telegrams constitute a valid and binding contract enforceable at law. (4) Revokation. — An offer is revoked by the death or insanity of the person making the offer, but if the offer is accepted prior to the death or insanity of the person making the same, this constitutes a contract which is binding on the executors, administrators, guardian or heirs of such person, provided the contract was not for personal services. (5) Misrepresentation. — If one party to a contract makes a state- ment which is in fact untrue but which he believes to be true, and this fact is a material fact or element in the contract, and the other believing the statement to be true and relying on the truth of it, enters into the con- tract, it may be avoided on the ground of misrepresentation. This is also true of a willful withholding or of nondisclosure of a material fact by one under special obligations to make the disclosure by reason of the fiduciary nature of the contract or the confidential relations of the parties. (6) Fraud. — "Fraud is a false representation of a material fact or nondisclosure of a material fact under such circumstances that it amounts to a false representation, made with the knowledge of its fal- sity or in reckless disregard of whether it is true or false, or as of per- sonal knowledge, with the intention that it shall be acted upon by the other party and which is acted upon by him to his injury."^ 3 Clark on Contracts, 3d Ed., page 272, Sec. 139. 154 Elements of Contracts The essential elements of fraud therefore are : (a) A false representation of a material fact. It is not sufficient that there be just a nondisclosure of a material fact unless the relation between the parties or the character of the contract makes it the duty of the party to disclose such fact or unless he took active measures" to prevent knowledge of the facts getting to the other party. (b) The representation must be as to a past or present fact, a mere expression of opinion or expectation, or an expression of intention, unless such intention does not as a matter of fact exist, is not sufficient to constitute fraud, nor is a false representation as to the law, as a rule. (c) It must be of a material fact, and a misrepresentation of an im- material fact even if made with fraudulent intent does not constitute fraud. (d) The party making the statement must know it to be false. It is held to have been made knowingly if it is said with reckless disregard as to its truth or falsity, or if the person making the representations had the means of ascertaining its truth or falsity and made the statement as of his own knowledge without endeavoring to find out, and, of course, if he makes a statement knowing it to be false. (e) It must be made with the intention that it will be acted on by the other party. It need not be made to the party himself but it must be intended to reach him and form a motive for his actions. (/) It must be relied upon by the other party and induce him to act, for no matter how fraudulent the representations, if the other party did not believe them and act on them he has not been defrauded. (g) The other must have suffered damage thereby. Contracts obtained through fraud are not void but voidable at the option of the injured party. (7) Duress. — If a person is compelled to sign a contract at the point of a gun or through threats of violence to him or some one whom he holds dear, he cannot be said to have consented to the contract but has been caused to enter into it by duress. The test as to whether or not there has been duress is whether the person really exercised a choice and exercised his own free wnll. Duress consists of the unlawful imprisonment or threat of imprison- ment of the other party or his wife, child, parent or other person for whom he has a deep affection, or the doing or threatening to do great bodily harm to such person, or the unlawTul seizure, detention or de- struction of the property of such person. A mere threat of a law suit, where the matter can be tried out by the courts, is not sufficient to con- stitute duress. Valuable Consideration 155 Contracts secured by duress are voidable at the option of the injured party. (8) Undue Influence. — Undue influence consists in taking advantage of a special trust or confidence which is reposed in one to cause or in- duce the person so trusting or having confidence in him to enter into a contract which is unfair to such person, in taking advantage of the weaknesses, superstition, or necessities and distress of another. A con- tract induced by undue influence is avoidable at the option of the party injured. § 104. There Must be a Lawful and Sufficient Valuable Considera- tion. (i) Definition: "Consideration ordinarily implies the giving of something for something, — quid pro quo. Theoretically and in princi- ple the consideration is supposed to represent a value equal to that rep- resented by the promise of the other party. * * * The law requires that the consideration shall have a legal value."* "A consideration is something esteemed in law as of value, in ex- change for which the promise in a contract is made."^ Considerations are of two kinds, ''good" and "valuable." A good consideration is one based on love, affection or blood relationship, and is founded on generosity or natural duty, a "good" consideration has been held not suflicient to support an executory contract. A valuable consideration is one where the law esteems that there has been an equivalent given for the act or promise, such as money, labor, a deed to land, exchange of promises to do something of value, etc. It frequently happens that deeds are made for a good as distinguished from a valuable consideration, and such deeds may, under some cir- cumstances be set aside in favor of creditors or others having rights against the person making the deed. (2) What Constitutes a Valuable Consideration. — A promise to do what one is already bound to do, or a promise founded on a thing al- ready done, a past consideration, will not as a rule be a valuable con- sideration. To constitute a valuable consideration a person must give or promise to give something of value, or he must give up, or promise to give up some legal right, as a promise not to sue or a promise to ex- tend the time of payment of a note, in exchange for some other thing of value ; for if A promises to extend the time of payment of a note without anything of value coming to him, the agreement is without con- sideration on the part of the other party. A promise of something or 4 Brown, Lectures on the Law of Contracts, pages 14 and 15. 5 Bishop in Contracts, 2d Ed., Sec. 38. 156 Elements of Contracts an act of value in exchange for a promise of another thing or act of value is a valuable consideration. A compromise of a matter in dispute is a valuable consideration. (3) Gift. — A mere promise of a thing of value is void as it is not founded on a valuable consideration, unless there is something of value given in return and is simply a promise of a gift ; but if the promise is carried out and completed by the delivery of the thing, this amounts to a gift which, as between the parties, cannot be reclaimed. Every contract to be valid must be founded on a valuable considera- tion, except that in the case of sealed instruments and negotiable in- struments in the hands of innocent purchasers for value the question of consideration will not be inquired into. A sealed instrument, as before stated, from its form imparts a con- sideration, and a negotiable instrument because of its character, will not admit of an inquiry or otherwise it would be of little value as a negotiable instrument. (4) Sufficiency of Consideration. — When a contract is founded on a valuable consideration, the courts will not inquire into the sufficiency of the consideration. That is, it is not necessary to the validity of the contract that the exchange which constitutes the consideration should be things, acts or promises of equal value, excepting where a contract is for the exchange of sums of money. In such a case the courts will re- quire that the exchanges be practically equivalent. However, it should be remembered that a decided difference in the value of things exchanged may be strong evidence of fraud, and, if the question of fraud is raised, may be the controlling or deciding element in setting aside the contract. § 105. The Subject Matter of the Contract Must be Lawful. If a contract is to be enforceable at law, the thing sought to be ac- complished by the contract must be lawful; the courts refuse to en- force a contract to do something that is not lawful and the illegality may consist either in doing something that is expressly forbidden by law, or something which is contrary to public policy. The principal classes of contracts opposed to law or to public policy are those : ( 1 ) For the sale of public office, public contracts or for the bribing of public officials. Example. — A, a government official with power to appoint assistants, con- tracts with B that if he, B, will pay $100 A will appoint B as an assistant. (2) Which tends to deprive the court of jurisdiction or to compound a crime. "An agreement to refer to arbitration incidental and subsidiary mat- Legal Contracts 157 ter in dispute, as a condition precedent to a right of action accruing, is valid, but if it goes so far as to completely oust the court of jurisdic- tion and substitute a forum of the parties own making, it is void because tending to endanger the tribunal established for the community as a whole."« Example of Compounding Crime. — A, being guilty of a theft, contracts with B, the principal witness for the state, to give B $1,000 to leave the country until after A's trial. This is a contract to compound a crime, that is to pre- vent the carrying out of justice. Example of Contract Depriving the Court of Jurisdiction. — A and B, who have entered into a contract for the construction of a building, agree that any dispute which may arise between A and B during the course of the work shall be referred to C, a disinterested person, for his decision as to the rights in the matter, and that the decision of C shall be final, and that neither party to the contract shall have a right to an action to determine his rights thereto. This agreement is plainly illegal because it tends to take away the jurisdiction of the court. (3) Contracts which tend to encourage litigation. Example. — A, knowing that B has a good case against C, contracts with B that if B will bring suit against C, A will furnish the funds to prosecute the suit and share whatever is received from C as a result of such suit. (4) Contracts for the committing of a crime or tort. (5) Agreements tending to promote fraud and breach of trust. Example. — A, an engineer, agrees with B, a contractor, that A will use his position as engineer of a large project to have the contract awarded to B, and that he, A, is to get a commission for such influence. (6) Which unduly affect the freedom or security of marriage. (7) Contracts in unreasonable restraint of trade and which tend to suppress competition at letting or sale by auction. Example. — An agreement not to bid at a public auction, if made for the purpose of stifling competition, is unlawful. "A general assignment or agreement to assign all invention there- after made by a party is not only contrary to public policy but is void under the patent laws of the United States. But a contract to assign future invention is valid where it relates to a particular subject and im- poses only such restraint upon the assignor as is fairly and reasonably necessary for the protection of the assignee under all the circumstances of the case. An illustration of such a reasonable and valid contract is a contract for the sale of letters patent for a machine "together with all improvement I may hereafter make."^ 6 Willis on Contracts, page 133. 7 Clark on Contracts, 3d Ed., page 392. 158 Elements of Contracts (8) To pay usurious rate of interest. Example. — The laws of a state provide that no greater rate of interest shall be agreed upon or received than 10% per year. A and B agree upon a rate of interest of 12% per year. This contract is void as it is usurious and the court will not enforce the contract. In some states they refuse even to assist in the collection of the prin- cipal, and in most states they simply provide that the principal shall be repaid to the person from whom it was borrowed, and no interest at all is collectable. (9) Any agreement the object of which is to injure the public health or safety. Example. — If a contract is made, the object of which is to obstruct drain- age and produce unhealthful conditions and thereby depreciate the value of adjacent property, such contract is unlawful since it is an agreement preju- dicial to public health and consequently is against public policy. (10) Agreements to establish unlawful monopolies, trusts, etc. Example. — If dealers in a necessary commodity combine for the purpose of controlling the output of such commodities and increasing the price thereof, the agreement to combine is unlawful as against public policy, it being a com- bination monopoly or trust for the purpose of establishing a restraint on trade. § 106. Statute of Fraud. The Statute of Frauds originated in England in what was known as 29. Car. 2 C 3, and was entitled "An act for the prevention of fraud and perjury." This statute required certain classes of contracts to be :^ in writing, and it has been adopted in some form or other by every state j in the United States. The statute requires the following classes of i contracts, or a memorandum thereof, to be in writing and signed by the \ party or parties to be charged thereby, or by his or their lawfully author- ^ ized agent : j (i) A special promise of an executor or administrator "to answer i damages out of his own estate ;" that is, to render himself personally ! liable for the debts of the deceased. -i (2) "Any special promise to answer for the debt, default or mis- carriages of another person." This class of contracts arises most often in business deals in the form of suretyship agreements or contracts creating a guaranty. j (3) Any agreement made upon the consideration of marriage. (4) Any agreement which "is not to be performed within the space of one year from the making thereof." (5) Agreements for the sale of any interest in land or for the leasing of land for a period of more than one year. Statute of Fraud 159 (6) Agreements for the purchase of goods, wares or merchandise for a price of fifty dollars or more, unless some payment has been made on such agreement, or a part of the goods has been delivered and accepted. Where contracts coming under the Statutes of Frauds are signed by agents, the authority of the agent must also be in writing and signed by the parties. § 107. Interpretation of the Contract. In general, contracts will be construed so as to give effect to the real intention of the parties. In determining what such intention is, the following rules are used : The intention will be gathered from the entire contract, and if there is a contradiction between printed and written parts thereof, the writ- ten part will govern. If the contract is capable of two interpretations, one of which would render it void or incapable of performance and the other valid or capable of performance, the latter construction will be given it. Words are given their plain or literal meaning except that evidence of local usage may vary their meaning and technical words will be given their technical meaning. If there is doubt as to the meaning of the contract, the construction given it by the parties will be given weight. Words are construed most strongly against the party using them. § 108. Penalties and Liquidated Damages. Contracts often provide that in case of a breach of the contract, the party aggrieved may collect of the other party a certain specified amount as liquidated damages, or simply damages. The courts will give effect to the intention of the parties provided the amount stated is, as a matter of fact, liquidated damages and not a penalty. In determining whether it is in fact liquidated damages, the courts will pay no attention to what the parties to the contract have called it. If the amount of damage is readily attainable and the amount stipulated is very much in excess of this amount, it will be deemed a penalty and therefore not enforceable. If it is indefinite and of uncertain value, the sum stipulated will be liquidated damages. It is not a penalty to make a debt, payable in installments, payable in whole on the failure to pay an installment when due. § 109. Discharge of Contracts. It is probably just as important for the engineer to understand how a contract may be discharged as it is for him to know how to enter into a valid binding and legal contract. The ways in which a contract may be discharged are many, and especially in engineering work is it im- 160 Elements of Contracts portant to have an understanding of some of these ways of dis- charging a contract. 1. The Discharge by Performance. The most common method of the discharge of a contract is by performance of the contract in accord- ance with its terms. If the contract is fully performed by both parties thereto, all rights and all obligations under the contract cease to exist for both parties thereto. Tender of Performance. Contracts are often discharged by a tender of performance on the part of one of the parties thereto. In contracts calling for a money payment, the tender must be made in money. In such cases the person so making the tender is relieved from the pro- visions of the contract, provided the other party thereto has failed or refuses to do his part. If the tender is for a less amount than is ac- tually due on the contract, the other party thereto may recover the amount actually due together with costs. In case of tender of services where services only are contemplated in the contract, if the person to whom the services are tendered refuses the same, then the person so tendering the services is entirely relieved from any responsibility under the contract and may sue the other party and recover damages for the failure of the other party to comply with his part of the contract. Example. — A, an engineer, enters into contract with B, who is to erect a sewage disposal plant, whereby A agrees to perform the engineering services in connection therewith. Because of the city ordinance making it unlawful to erect a sewage disposal plant at the point agreed upon B decides to abandon the project. A offers his services to B who refuses them. The contract there- by is discharged so far as A is concerned and he may sue B for damages be- cause of his failure to live up to his part of the agreement. Where two parties are to act at the same time, neither party can col- lect from the other because of the failure of the other party to comply with the terms, unless he himself is ready and willing and offers to comply with the terms of the contract. Example. — A contractor agrees to purchase a dynamo from an electric company, the same to be of a special design and to be ready for delivery at a specified date. The dynamo is not ready on the date agreed upon and the contractor who was to have received the dynamo refuses to accept the dynamo when it was prepared later and sues the electrical company for damages. He cannot collect unless he can establish that he was ready and willing and offered to pay for the dynamo at the time when the same was agreed to have been delivered. 2. Impossibility of Performance. Perhaps no method of discharg- ing the contract is of more interest to the engineer than this one. The Discharge of Contracts 161 engineering contractor is continually running into conditions of soil, streamflow, climate and other conditions which could not have been and were not foreseen prior to the undertaking of the work, and it is important that he understands the effect of these unforeseen conditions on the contract before entering into such a contract. If the contractor contracts without reservation to do a certain piece of work in a certain way and within a given time he is absolutely bound by his contract to do the work in the manner specified and within the time specified, provided he has not made some provision in his contract for the extension of time or for extras for unforeseen conditions or un- less the person with whom he contracted has by his representations to the contractor practically warranted th^ conditions which will be en- countered in the work. Example. — A, an engineering contractor, contracts with B that he will con- struct the foundation for a structure of a general type and of approximately a given depth. In making excavations for the foundation he finds the soil conditions which make it necessary, in order to insure the safety of the foun- dation, to greatly enlarge the foundation planned by increasing the depth to which the foundation is laid, and this increase practically doubles the cost. The question now is, what is the effect of this unforeseen col Jition which practically renders the contract as originally contemplated impossible of performance. If he agreed in the contract without reservation to build the foundation to a certain depth to insure the safety of the structure, he must go ahead and complete the contract as originally contemplated. If, however, he provided in the contract that in case of conditions such as this he was to re- ceive extra pay, or that a new contract was to be entered into relative thereto v^hen the conditions were found, he then is excused from any further per- formance of the contract in that particular. If a contract is made for personal services and the person whose serv- ices were contracted for died, then the contract is discharged by the death of the person because of the impossibility of his rendering such services. If the subject matter of the contract, or the thing whose continued ex- istence is essential to the carrying out of the contract, is destroyed through no fault of the promisor, as by an act of God, then the contract is discharged. Where the performance of a contract is rendered impossible by a change in the existing law then the contract is discharged. Example. — If a brewery prior to January, 1919, had entered into a contract to deliver a given amount of its product for a period of ten years next succeed- ing the contract, the ratification of the National prohibition amendment to the constitution would have changed the law so as to render the contract im- possible of performance and the contract would thereby be discharged at the time when the law went into effect and rendered the same impossible. 162 Elements of Contracts 3. Substantial Performance. Another matter of vital interest to the engineer and the engineering contractor is the subject of substantial performance, for in most cases of engineering contracts there is not an exact performance of the contract but a substantial performance there- of. This is a highly technical subject and one which should be very thoroughly understood. It is impossible within the confines of this chapter to give an extended discussion of this matter, but engineering students should consult standard texts for a full discussion thereof. It is not necessary here to discuss or to define the technical meaning of substantial performance. It is simply necessary to state that by substantial performance, in a general way, is meant the practical com- pletion of the work so that no material parts thereof remain to be done or so that there have been no material alterations from the original con- tract. Wait, in "Engineering and Architectural Jurisprudence," says the question is not one of law but a fact for the jury, which determines whether the defect is technical or unimportant, whether there has been a substantial performance, and also whether the departure and omis- sions were intentional and willful. The right to collect for substantial performance of a contract is what is known as an equitable right as opposed to a legal right and it is a rule of equity that one seeking to enforce an equitable right must come into court ''with clean hands," that is he himself must not have been at fault. It follows therefore that if one has willfully departed from the terms of the contract or has intentionally substituted materials for other materials which were specified in the contract and which were available that he cannot recover in a court of equity. If, on the other hand, cer- tain materials were specified in the contract to be used or a certain method of doing the work was specified and the materials specified were not obtainable but another material, substantially of the same grade was obtainable, or if certain methods of doing the work were specified which could not be used beca ise of circumstances which arose and another method of doing the work which was substantially equivalent to the method prescribed was available and it was used, that would con- stitute a substantial performance of contract. Substantial performance is a question of fact for the jury and not a question of law, it therefore follows that the question as to whether or not there has been substantial performance depends in a great measure upon the character of the jury which may decide upon the particular question, and it is well for engineering contractors to keep in mind that there is the human element to deal with in all matters of this kind, and Discharge of Contracts 163 in determining whether to bring a suit for collection on the grounds that there has been substantial performance, this should be considered. A contract may be so drawn that it consists of several distinct and separable parts and it often happens that one part of the contract which is separable from the other parts is fully performed and if the con- tractor quit work when that separable part was completed he may re- cover for the work so done. One of the tests of substantial performance is whether the structure is reasonably adapted to the purpose for which it was built, and it has been held that when the roof of an addition to a house is five inches too low, the mistake not affecting its appearance materially that the contract had been substantially performed (Overlies vs. Bullinger, 132 N. Y. 598) ; the defects of $275.00 on a $7,000.00 job were held not inconsistent with substantial performance where the contractor tried to fulfill his contract (Valk vs. Mekenzie 16 N. Y. Sup. 741). 4. Discharged by Agreement. A contract may also be discharged by agreement between the parties thereto. If the contract has not been performed by either party thereto, the same may be discharged by the mutual agreement of the parties, the consideration for the discharge be- ing the mutual release of each party by the other. Contracts may also be discharged by agreement by the making of a new contract between the parties to the old contract, the terms of which are inconsistent with the terms of the old contract or the terms of which provide that it shall be substituted for the old contract. A contract may also be discharged by a release under seal which imports a consideration or a release founded upon a sufificient consideration and signed by the parties to the contract or by changing the parties to the contract whereby a new party is sub- stituted for the previous one by agreement of all three of the parties to the substitution while the terms of the contract may remain the same. The party for whom the new party was substituted is thereby dis- charged from any liability and from all rights under the contract, pro- vided there has been no performance by either of the parties thereto. It often happens in an engineering contract that unforeseen condi- tions arise after the contract has been started and the parties to the old contract enter into a new contract which fits the new conditions. They are thereby discharged from the conditions of the old contract and bound by the conditions of the new one. It should be remembered that contracts under seal can be discharged only by agreement or release also under seal, and any contract under the Statutes of Frauds which is thereby required to be in writing must be released by an agreement in writing. If the statute of frauds does 164 Elements of Contracts not require the agreement to be in writing, it may be released either orally or in writing even though the original agreement was in writing. One party to a contract who has performed his part of the contract may, for a reasonable consideration, waive his rights to the performance by the other party thereto. 5. Discharged by Operation of Law. Contracts may be discharged by operation of law either by merger of one contract into another, altera- tion of the contract by one party thereto without the consent of the other party, or by the bankruptcy, either voluntary or involuntary, of one of the parties to the contract. Clark in his work on contracts, page 599, says : "Acceptance of a higher security in place of a lower merges or extinguishes the lower, but "(a) the two securities must be different in their legal operation, the one of a higher efficacy than the other. "(b) the subject matter of the two securities must be identical. "(c) the parties must be the same." Example. — If A and B enter into a contract whereby A agrees to purchase a certain tract of land from B and to pay him $1,000 therefor, if B later deeds the land to A upon the payment by A of the $1,000, then the simple con- tract for the purchase of the land merges with the deed as the deed is the higher form of security. Alteration of a Written Instrument. If one of the parties to a writ- ten contract alters, or causes to be altered, material parts of the contract without the consent of the other party thereto, the other party to the contract will be discharged of all liabilities under the contract but will be entitled to any benefit accruing therefrom. If the instrument al- tered is a negotiable instrument and is altered by the party holding the same, the parties liable thereon are relieved from all liability thereunder unless the instrument is later negotiated and gets into the hands of an innocent purchaser for value who may then enforce the original ob- ligation of the contract. Alterations on notes, bonds, checks and ne- gotiable bills of lading and other negotiable instruments come within this class. Discharged by Bankruptcy. Under the bankruptcy laws of the United States any person who has been declared bankrupt and whose estate has been administered and who has received a discharge in bankruptcy will be relieved from all liabilities and all contracts of whatever nature which he has entered into prior to being declared bankrupt. 6. Discharged by Breach of Contract. If either party to a contract either announces his intentions not to fulfill the terms of the contract or wholly or partly fails to perform some of the conditions of the contract, Discharge of Contracts 165 there is a breach of the contract which gives rise to rights on the part of the injured party either to give him a right of action against the other party or in some cases he may apply to a court of equity for a specific performance of the contract. In the case where a person contracts for the conveyance of land upon the payment of certain money if the person agreeing to pay the money is ready and willing and tenders the money, and the party who agreed to convey the land refuses to convey it, the injured party may then go into a court of equity and the court will enter a decree compelling the conveyance of the land to the party to whom the land was agreed to be conveyed. As a rule a breach of the contract by either party thereto discharges the contract and relieves the other party to the contract from all liabilities thereunder and gives him a right to sue the party so failing to fulfill the terms of the contract for damages for such breach. (7) Discharged by Statute of Limitation. The laws of the several states of the United States also provide that certain contracts must be sued upon within a given time after the right of action arising under the contract has accrued or else all liability thereunder ceases. If A gives a note to B for $50.00 payable one year after date, B acquires the right to sue A at the end of the year on the note. If the statutes of the state provide that the action on such note must be commenced within six years after the cause of action accrued if the action is not commenced within six years from that time then B cannot recover from A the money loaned on the note and the contract is discharged through a lapse of time. Or, if the instrument is a sealed instrument, the statutes of limitation usually run for 20 years, that is if an action arose upon a contract under seal and a breach of the contract was made on the first day of January, 19 10, action to recover damages on the contract must be commenced on or before the first day of January, 1930, or if action was not commenced the contract provisions and all liabilities and rights thereunder would be discharged on the first day of January, 1930, by a lapse of time. Remedies for Breach of Contract. Where there has been a. breach of contract, certain rights are acquired by the injured party. He may either sue and recover damages actually sufifered by him or he may enter into an agreement with the other parties of the contract to accept a cer- tain amount in payment of the breach. This is commonly known as an accord and satisfaction and the usual method pursued then is for the injured party upon the payment agreed upon to give a formal release of the contract and all liabilities and rights arising because of the breach of the contract to the other party so paying the money. 166 Elements of Contracts Where the injured party sues and recovers a judgment against the other parties thereto, that operates as a discharge of the contract and gives rise to new rights on the part of the injured party and new liabili- ties on the part of the other party to the contract which may be inforced by judicial procedure by attaching -the property of the party against whom the judgment is obtained and selling the same to pay the amount recovered in the judgment.

First: The day labor system, in which an organization consisting of superintendents, foremen, mechanics and laborers is employed and the material purchased by the municipality or owner and the work is undertaken independently of contractors. Second: The contract system by which men or firms who make a business of construction are employed under some form of contract to undertake the work. Each of these systems has its advantages and disadvantages. Each may be entirely satisfactory under certain conditions and very unsatisfactory under other conditions. The choice of system must de- pend on the selection of the lesser of two evils when all conditions are considered. From the point of view of the parties having the work done the choice will be made of the system which will secure the lowest cost of construction, the best workmanship, promptness of construc- tion and the elimination of contingences to the greatest degree. It is important for the owner that the actual cost of the work should be closely known in order that he may determine whether the work can be financed and whether its construction will be war- ranted by the results that will be obtained from the investment. The contractor is equally interested in the cost in order that he may definitely know that he can complete the work for a given sum and with a certain profit. Both owner and contractor are interested in a definite knowledge of all of the conditions involved in order that it may be possible to closely estimate what that actual cost will be. The owner often assumes that he can eliminate uncertainty by inducing the contractor to assume all responsibilities, take the risk of all uncer- tainties and undertake the construction at a fixed sum. This can be and frequently is done, but for such service as well as for all other services, payment must be made, and the prices paid for work per- formed under such conditions are usually excessive. When the nature of the work is such that its character and extent can be accurately defined and when plans and specifications for such work are so prepared that they are clear and complete, the uncertain- ties are largely removed and contracts let to responsible and experi- 168 Day Labor and Contract Systems enced contractors are usually satisfactory. When, however, the con- ditions are indefinite and indeterminate, as they may be in hazardous and novel construction because of incomplete investigation of conditions or from imperfect and indefinite plans and specifications, any estimate made must be more or less uncertain and will involve a serious risk. Such conditions must result either in exorbitant prices or the assump- tion of serious risks at a low price by contractors, who, under such conditions are apt to be more or less inexperienced and irresponsible. In the latter case, especially if the risk assumed by the contractor is realized to his detriment, there is a strong tendency for him to en- deavor to recoup his possible losses by furnishing and doing as little as he can under his contract. This often results in disagreements and litigation and quite likely in poor work and general dissatisfaction. In the fixed sum contract the interests of the owner and con- tractor are, in the main, directly opposed. The owner's desires are as previously outlined. The contractor's interest lies between a desire to obtain maximum profit and to establish or maintain a reputation for honesty, efficiency and ability. The latter desire will induce the re- sponsible contractor to carry out his contract even at a loss but is in- sufficient for such purpose with an irresponsible man. The day-labor system seems to offer a way of avoiding the diffi- culties of securing proper work under the contract system. Here, however, the owner exchanges the uncertainty of the honesty, ability and experience of the contractor for similar uncertainties in regard to an organization w^hich he may have to establish for the special work at hand. In many cases he may find that the evils he has assumed are as great as or greater than those which he has elected to avoid. The problem then is to choose such business methods of construe^ tion as will avoid these difficulties so far as practicable. The answer is not apparent and indeed cannot be always the same, for the difficul- ties in various undertakings are so different that they must be met in each case in a different way and as the circumstances seem to warrant. § III. Uncertainties in the Cost of Work. — Difficulties, to be eliminated, must first be recognized, and one of the greatest difficulties in the way of securing the construction of work at reasonable cost lies in the uncertainties as to what that cost may be. These uncertainties arise from various factors which are here briefly outlined. A. The Engineer. — To the owner who proposes to undertake the construction of a plant or other piece of work, the uncertainty involved in the selection of an engineer is not the least of his troubles nor an un- important factor in the expense of his undertaking. IMuch depends upon the honesty, integrity, judgment and ability of the engineer. For Uncertainties in Cost of Work 169 the best results, he must be a man who will make the interests of his client his own interests so far as equity will permit ; his honesty and integrity must be beyond question ; his judgment must be developed by knowledge and experience ; he must have the ability to design econom- ically and to supervise intelligently the construction proposed ; he must have sufficient self-knowledge to recognize this own strength and his own weakness, and sufficient character to subdue his personal pride and to demand and secure adequate advice on the subjects on which such advice is needed. An engineer with all such attributes is seldom available and such qualifications can only be approximated. No for- mulas can be offered for his successful selection. Careful inquiry among those who have had similar work performed, and observation of the ability developed by men in similar work, are the best bases for such selection. An engineer may be highly successful in one field and be a serious failure in some other which is radically different. It lies within every young engineer to develop these attributes of success to a greater or less degree ; much will depend upon his individual will-power to make himself available for responsible service. To the contractor, the engineer is an equally important element of uncertainty, especially where local conditions are unknown, plans and specifications are incomplete, and the contract places large discretion- ary powers in the hands of the engineer. Is the engineer honest, ex- perienced and competent? Is he inexperienced, arbitrary and unfair? Will he shoulder his own mistakes or cover his errors, so far as pos- sible, at the contractor's expense? The answers to these questions would remove one of the greatest uncertainties in the cost of work to the contractor; but unless the contractor has had previous experience under the same engineer, these questions can be answered only by ex- perience. B. Local Conditions. — Complete information covering local condi- tions, full and complete specifications, a fair contract and provisions for the arbitration of disputed questions will remove much of the uncer- ta'ntv. These can be removed to a greater or less extent by thorough investigation which should be imdertaken by technical experts employed bv the owner. The results of the investigation should be made avail- able to those who undertake the construction, who should also be re- quired to make such additional examination and investigations as will give them a personal knowledge of the conditions involved, so far as practicable. C. Plans. — Complete and definite plans can be based only on a complete and definite knowledge of the local conditions. They must 170 Day Labor and Contract Systems be indefinite to the extent that the knowledge of the conditions are in- definite. Complete, definite and proper plans can be prepared only by those who have sufficient knowledge and experience. Indefinite plans are frequently the result of indefinite information as to what should be required. D. Specifications. — Specifications, like plans, are dependent upon both a knowledge of conditions and a knowledge of how the conditions should be met in order to secure the results desired. Their proper preparation is further complicated by the difficulty of so expressing the meaning and intent of the writer that they will clearly convey the same to the reader, and by the fact that their meaning may have to be interpreted under conditions which were not foreseen. E. Contingencies. — Even when a fairly thorough preliminary in- vestigation has been made, and where complete and definite plans and specifications have been prepared, contingencies cannot be eliminated although they will have been reduced. No reasonable investigation can be so complete that it will disclose all conditions that may develop during construction. If some contingencies become of minor import- ance on account of well defined local conditions, other contingencies may arise. Weather conditions may prove unpropitious and cause in- creased expense. Continuous rains may set in and delay work and cause more or less damage. Severe cold weather may reduce output and require protection in the performance of the work. Floods may come and cause great damage, and even tornadoes or heavy winds have added to the toll of extra expense which could not be foreseen. F. Casualties. — Construction work is frequently accompanied by casualties more or less serious. These can be greatly reduced by care and watchfulness, but mankind will never become sufficiently reliable to eliminate them altogether. On construction work, every man is de- pendent for his safety on his fellow men, who are more or less careless and unreliable, and on tools, machinery and apparatus that are liable to contain unknown and serious defects. The results are in- juries or death, and damages and destruction, all of which add to the expense involved. G. Transportation. — Almost every structure is dependent to some extent on transportation for its prompt construction and cost. This will probably be satisfactory but may cause trouble. The possibilities of freight congestion, misshipments, wrecks and various disasters add to the uncertainty and expense. H. Equipment. — The satisfactory completion of construction de- pends upon promptly securing the proper equipment for construction purposes as well as the necessary equipment for the project to be con- Uncertainties in Cost of Work 171 structed, both of which involve more or less uncertainties because others than the principals to the construction are involved. Manu- facturers may have other orders that have precedence or may be unable to secure the materials necessary for making the equipment, and many other causes make this an item of extra expense. /. Material. — To secure material when needed and at a reason- able price is often a serious difficulty. Both items must be ascer- tained as a basis for a cost estimate, but as an ordei^ can seldom be placed at the time the estimate is made, both delivery and cost may change before construction is possible. /. Supervision. — It is exceedingly difficult to secure suitable su- pervision for construction work. Firms having an extensive business usually keep a number of dependable men on whom, from their previ- ous experience, they can reasonably rely. Even such firms cannot keep all of the superintendents, foremen, etc., that they need when business is at its best ; and they must depend on their ability to select and secure suitable men for temporary positions. The problem be- comes more difficult and uncertain when an entire force is to be organ- ized for the purpose of a single construction. Letters and recommendations may assist in the selection of such men, but there is no way by which actual fitness can be determined ex- cept by trial, and repeated trials are often necessary. A superintend- ent or foreman who is inexperienced or unsuited to a certain position, may and frequently does add greatly to the expense of the construction. K. Labor. — Skilled and unskilled labor is one of the important variables in the cost of construction. The ability to secure suitable men in sufficient numbers for the prompt completion of construction will greatly reduce cost. When men are in great demand they are hard to secure, the force employed becomes inadequate and not only is the work delayed and the cost of supervision increased, but the men themselves become less efficient. When jobs are scarce and hard to find, the men on the work are attentive and efficient ; but with plenty of work and labor in demand, they become independent and inefficient. The price of labor advances and the amount performed per individual becomes less. These changes frequently occur after an estimate is made and must be considered as serious uncertainties in all estimates. L. Combinations. — Illegal combinations are among the uncertain- ties that will cause extra expense in construction. Combinations of contractors, material men and manufacturers are not unknown, and often seriously afifect prices. They can seldom be proved, but they are often no less real. They can often be recognized only by a very defi- 172 Day Labor and Contract Systems nite knowledge of actual values, and their effects on cost can some- times be obviated only by the rejection of offers and the refusal to proceed until such condition can be eliminated. M. Graft. — The form of dishonesty known as "graft" is more common to public than to private work, because the opportunities in public work are greater. It results from private combinations of dis- honest men who have some influence which can be used to secure the acceptance of unfair prices or unfair work, and a consequent dishonest profit which may be divided among them. No high grade contractors or engineers, worthy of the name, ever enter into such dealings, and while this disreputable defect in business relations is still occasionally encountered and still needs watchful attention, it is believed to be less common than is popularly supposed. A^. Politics. — This evil creates some of the most important uncer- tainties in the cost of construction of public works. It sometimes re- sults in forms of graft which have been previously mentioned but it often takes forms which, while objectionable, hardly justify so severe a title. Political influences are commonly exercised to secure appoint- ments of superintendents, foremen and inspectors who are unqualified for the work, and labor that is ineflicient or incapacitated. They may be exercised to reduce hours of labor and to increase unduly the com- pensation paid. The reasons behind this may sometimes be laudable, as for example, the desire to improve labor conditions, the desire to afford work to the unemployed ; or they may be unscrupulous when ex- ercised for personal influence. In any event, politics is one of the seri- ous uncertainties which must be considered in the cost of public works. To the above might be added legal complications, and perhaps other factors which are only indirectly covered in the above analysis. Enough has been said, however, to present fairly the difficulties in the case. Were all of these factors present in every piece of construction, the chances of making estimates that would be reasonably close to the actual costs which could be secured by any method of construction, would be very remote. § 112. Force Account Construction. — The construction of engi- rieering work by force account independent of contractors, eliminates certain difficulties involved in work let under a contract, but introduces other difficulties often no less serious. The responsibility for the con- struction and for the cost of the work is placed on such organizations as the owner or municipality may create for the purpose, and the re- sult depends largely on the efficiency of such an organization. Where Force Account Construction 173 the work is continuous there is no vaHd reason, except the local condi- tions, why such an organization may not be established on a business basis and accomplish results which are fairly comparative with the re- sults which can be accomplished by work done under contract. The possibility of creating an efficient organization is, therefore, the prin- cipal point to be considered. In public organizations there is always the danger that there may be interference in the personnel of the organization and in its activities which will seriously handicap and injuriously affect its efficiency. In such organizations, especially in public work, there is not the per- sonal responsibility for accomplishing proper work at the lowest first cost that obtains in works let by contract. There is no personal in- centive to keep the construction cost at the lowest price in order that there shall be no personal losses and a maximum of personal gain. Frequently this lack of responsibility is felt in common by all engaged on the work, from the laborer to the highest authority. Excessive cost is commonly excused on the basis of supposedly better and more satisfactory construction. The advantages and disadvantages of force account as applied to public works are analyzed by the author as follows : Day-Labor or Force- Account System for Public Work. Advantages. Disadvantages. 1. Employment of local labor. 2. Saves contractor's profit. 3. Eliminates scamping and ineffi- ciency of contractor. 4. Eliminates difficulty of drawing contracts for complex construc- tion. 5. Permits flexibility and ease of modifying plans. 6. Saving in cost of inspection. 1. Politics, higher wages for labor, shorter hours, and less efficient labor. 2. Usually entails greater actual cost of construction. 3. Introduces inefficiency of superin- tendents and foremen due to lower wages and political influ- ences in appointments. 4. Difficulties more fancied than real and can be overcome by em- ploying efficient and experi- enced engineers. 5. Leads to careless investigation and design and unsafe esti- mates. 6. No real saving possible, inspectors are necessary to prevent care- lessness by foremen. 7. Difficulty of fixing responsibility. 8. Tendency to maintain organiza- tions when not needed. 174 Day Labor and Contract Systems Under favorable circumstances and for certain purposes the ad- vantages may offset the disadvantages, but such conditions are Hmited. Mr. H. P. Eddy, who investigated the efficiency of certain city de- partments of Boston for the Boston Finance Commission, presented a paper before the Boston Society of Engineers which gave much pertinent information on this subject. In order to determine the general practice of cities doing work on extension of water pipes and sewerage systems by day labor or by contract, the following information was obtained: Of fifty-eight cities reported concerning the methods used for water pipe extension one- third were doing work by contract, but outside of New England forty- eight per cent were doing the work by contract. Of seventy-three replies in regard to methods used for sewer construction fifty-two were doing work wholly by contract, but outside of New England forty-eight of fifty-one cities reporting were doing work by contract. In Massachusetts seventeen out of eighteen reporting were doing work by day labor. While recognizing the abuses in the contract sys- tem, Mr. Eddy, nevertheless favored that system on account of the greater abuses in the day-labor system. In work done by day labor he found a strong tendency through political influences to employ older and less efficient labor, to increase wages above the compara- tive wages paid by contractors, to shorten hours, to pay wages for Saturday half holidays, general holidays and during sick leave, and by such means to greatly increase the cost of construction. In a comparison ,of eight comparable pipe sewers laid in Boston by day labor and by contract he found the additional cost of work done by day to be from 48 per cent, to 220 per cent, of the cost of similar work done under contract. Similar figures and conclusions can be drawn from various sources, and while, in some cases, evidence is available to the contrary, such cases are believed to be the exception and not the rule. Where the manager of work done by force account is directly re- sponsible to an owner who gives personal attention to the expendi- tures involved, the objections enumerated above become less valid and better results can commonly be secured. When, however, an organ- ization is effected for the purpose of a single construction, the manage- ment is confronted with the difficulties of securing suitable, experienced and efficient supervision. The best superintendents and foremen are commonly permanently engaged with contractors who have a per- manent and continuous business, and men so employed do not care to break such connections for a position which can be at the best only temporary, and which may leave them at the close of the job without Force Account Construction 175 permanent connection. This factor is so important that in order to secure good men it is usually necessary to pay excessive salaries. The manager is at the further disadvantage of having no personal and inti- mate knowledge of the capacity and reliability of the men he must em- ploy, and he must frequently secure them only to find that they are un- suitable for his purpose and are available only because their idiosyn- crasies have made them unsatisfactory for permanent connections. Another serious handicap is the necessity of purchasing an entire construction plant and tools for a particular job, which at its close can be sold only at a considerable sacrifice. Even the purchase of such equipment requires extensive experience and knowledge of the par- ticular contract involved. The engineer, or whoever must undertake the responsibility of carrying out work of construction en this system, should fully appre- ciate his responsibility and the probable effect of any failure on his client's welfare and on his own reputation and future prospects. Such v/ork should be attempted on^y by those who have had actual and ex- tensive experience, and who have a detailed knowledge of men, equip- ment, and business methods which are not commonly acquired with an engineering education. § 113. Contract at a Fixed Price. — The oldest and most com- mon method of letting work under contract is by receiving competitive bids of fixed prices. These may be either lump sums or unit prices on each of a number of items which together constitute the entire work. Contracting on a basis of either a lump sum or of unit prices is subject to the objection that the interests of the contractor and of the owner become at once antagonistic. It is the owner's purpose to secure the best quality of work and material at the prices paid, while the natural purpose of the contractor is to do the work as cheaply as possible and to economize in both the character of material and ex- pense of labor, so far as the conditions permit. If the contractor is a man of character, experience and reputation, and if his proposal has been based on definite and clear plans and specifications, his agreed price will contain a sufficient profit to assure the execution of the work in a satisfactory manner. If, however, he is unreliable and inexperienced, and places the desire for profit above reputation, he may take the work at such a price as to assure a loss if he fulfills his contract. In this event, or possibly in any. case, the letting of construction work to such a man will involve constant trouble, and usually produce poor results. Work let under contract should, so far as possible, be let only to men of experience and standing. 176 Day Labor and Contract Systems '^ In any but the simplest forms of work that can be clearly and definitely planned and specified, unit prices rather than a lump sum should be required. The letting of work for a lump sum may lead to exorbitant payments for any extra work required. Where a lump sum is bid and a change in the work is made, a supplementary contract must be drawn and a readjustment made in the price to be paid. In such cases the contractor has a distinct advantage, for his compensation is fixed and his own price must usually prevail for any extra work in- volved. The lump sum contract gives no information as to what the contractor regards as a fair price for each item of the work he is to perform, on which information the deductions for work omitted and the extra payments for work performed might be based. While new work under a contract may be done on the basis of force account, such a method under contract conditions is usually unsatisfactory. The labor will usually be inefficient. When the laborer knows he is work- ing for the company, the state or the city, his incentive to do his best is gone, for all lost time simply adds to the profit of his employer. For this and other reasons, force account work under contracts should be avoided wherever possible, and it can be largely avoided by the use of the unit price system of bidding, which can be used for extra work arising out; of change of plans. Force account also means added work for the engineering department and careful supervision to see that the pay roll is not padded. Notwithstanding its disadvantages, the fixed price system of con- tracting has been found the most practicable method for general con- ditions. It is based on the same principles as other similar business transactions and therefore appeals to the majority of business men. It also has some additional advantages to the owner in that while the actual cost may be high, a definite limit is fixed, the cost is known be- fore the work is begun, and if the price is too high the work need not be undertaken. When business men undertake to construct a plant or to erect a building, they naturally proceed in the same manner that they would follow in other business undertakings. They commonly neglect to consider the fact that they are beginning an undertaking of which they are ignorant and are depending on a personal advisor and his ability to design, supervise, and secure adequate construction. In such cases, invitations to bid are usually confined to responsible con- tractors, but an endeavor is made to let the work at the lowest practic- able price in order that they may secure the most for their money, as Contract at Fixed Price 177 in other business transactions. With complete plans and specifica- tions, properly and clearly prepared, the results are fairly satisfactory. When for any reason the price bid is too low to cover the cost of the work, the problem of securing proper construction at an unfair price arises. Many contractors under such circumstances will face the loss, and complete the work in first class and satisfactory manner ; but it is also true that there are many others who will take every advantage possible in order to effect a saving. When the work is of a well known character and the services to be rendered are thoroughly defined, a lump sum contract is unobjectionable; but as soon as serious elements of hazard enter the undertaking, such a contract becomes uncertain and must either be taken at an exorbitant figure or at a great risk of loss. Under such conditions, either the force account system or some other form of contract becomes desirable. § 114. Excessive Waste in Competitive Bidding. — The expense to contractors in estimating on work which they do not secure, results in a great economic waste from competitive bidding as it is now con- ducted. The Illinois Chapter of the American Institute of Architects in 1907 gathered statistics from five representative contractors who made competitive bids for buildings, costing from $100,000 to $150,000. From these statistics it appears that the average number of contracts estimated by each builder was seventy-two, and the average number of contracts taken, ten. The average expense of each estimate to the general contractor was $125 and in addition the expense incurred by subcontractors and material men was $378, making a total of $503 spent on each estimate by the contractor, subcontractors and material men. In addition to this expense, the head of each firm spent an av- erage of twenty-one per cent, of the total time given the office business on these estimates. The average number of general contractors esti- mating on each building was approximately six, making a total cost of $3,018 on each building or from two to three per cent, of the cost of the building. Taking the total number of estimates made for the five contractors and deducting one-third for subcontractors' estimates used in com- mon by the general contractors, leaves approximately $120,000 as the total cost for estimates made on all work by these five firms. As the five contractors secured a total of fifty contracts, the expense of the bids from which work was secured was $25,150 and the expense in- curred for estimating contracts which were not secured was $95,000, which amount was a dead loss to the five contractors, subcontractors 178 Day Labor and Contract Systems and material men in one year. This loss must be met indirectly, in the long run by the owners of the buildings erected. The committee in making this investigation estimated that in 1906, $63,000,000 in building work was done in the city of Chicago and that the expense of estimating was at least $1,260,000, of which $1,000,000 was fruitlessly spent on unsuccessful estimates. The committee suggested that this expense might be curtailed by employing a professional estimator to make a complete estimate of all labors, materials and expenses involved in a proposed building. This estimator should be paid by the owner and should be absolutely inde- pendent. The committee expressed the opinion that the nature of the estimator's position would enable him to secure low prices for the great mass of material by eliminating middlemen's profits and reducing op- portunities for combinations. It was suggested that the owner should go over the plans and specifications of the building and the estimator's report of the cost of construction, and if he found the cost satisfac- tory, he should turn the papers over to a contractor satisfactory to himself and his architect. If the contractor was also satisfied with the amount of the estimate, he could be given the contract for the esti- mated amount, plus a fixed fee, depending upon the character and mag- nitude of the structure. At the completion of the work, if the building costs less than the estimate, the committee suggests that the amount should be divided equally between the contractor and the owner ; while if the cost ran above the estimate, the loss should be equally divided. They believe that in this way the interests of the owner and of the con- tractor could be made the same, and that their relations would there- fore be harmonious instead of antagonistic. The difficulty in making such arrangements would probably be due largely to the lack of ac- quaintance between business men and contractors and to the fact that, as few men put up more than one or two buildings, they would natur- ally see greater economy in competitive bidding than in awarding the contract without competition. The suggestion is, however, worthy of careful consideration, as some system of preventing unnecessary expense is desirable and all practicable economies will result both in reduced cost of construction and greater profits. § 115. Contracts for Cost Plus a Percentage. — To obviate the difficulties of the fixed price contract, various methods have been sug- gested and tried with results more or less satisfactory. The most com- mon method has been to pay the contractor the actual cost of the Cost— Plus Contracts 179 construction work with a specified percentage thereof as compensation for his overhead expenses, personal services, and profits. The advantages claimed for this system are that, as the risk or hazard of construction is entirely removed from the contractor, the owner can secure his services with the advantages of his skill and ex- perience for the lowest practicable amount. While the owner is obliged, in this case, to assume the hazards or contingencies of construc- tion, he will pay only such costs as are actually incurred and for which he should equitably pay. There is no doubt but that the removal of hazard is an important factor in low bidding. Any successful man must charge prices which are sufficient to cover not only the actual cost which can be intelligently estimated, but also those contingent expenses which cannot be ac- curately foreseen but which, nevertheless, will surely occur. Tenders from responsible contractors for work at a fixed price are bound, there- fore, to be high enough to cover reasonable and possibly unreasonable conditions. The percentage basis for the letting of contracts is, however, open to objections. One important objection is the fact that every increase in cost increases the amount payable to the contractor. Increased cost, while a detriment to the owner, is a direct financial benefit to the con- tractor. Not all contractors are strong enough morally to withstand the resulting temptation. Another serious drawback to all forms of contracting for cost plus a certain definite or variable return to the contractor is due to the inefficiency of management which is likely to result where a contractor's profit does not depend on his ability to do work economically. Where he has little or no financial interest in the actual economy of construc- tion, the personal care in the choice of men and equipment and the close supervision which obtains under fixed sum contracts are often missing, with more or less unsatisfactory consequences. Experience shows that it is almost or quite impossible to secure efficient working conditions under the cost plus percentage arrange- ment. The foremen and laborers, appreciating the fact that the con- tractor to whom they are directly responsible is not dependent on their greatest eflForts for his returns, will almost uniformly reduce their ef- forts, with a resulting increase in cost and perhaps a detriment to the quality of work. While the lump sum price assures personal responsibility, the con- tractor will not attempt work unless he feels confident that he can prop- 180 Day Labor and Contract Systems erly equip the same with suitable plant and supervision, as otherwise his chance for a profit would be small. In prosperous times, when the amount of work to be done is considerable, there is a strong temptation for the contractor, under the cost plus a percentage system, to take all work offered regardless of his ability to furnish suitable supervision and equipment. Such conditions are of course disastrous to low cost of construction and to satisfactory work. The use of the percentage form of contract should therefore necessarily be limited to firms with well established reputations, and must be confined to work for private companies not bound by the legal restrictions which govern public works. Under certain conditions such a plan is undoubtedly desirable. In extending the rapid transit system of New York City it became nec- essary to construct a third track on the Second, Third and Ninth Ave- nue elevated railway lines. The difficulties in the way of the extensive improvements required were serious, and it was necessary to effect the improvement with a minimum risk of danger and the least prac- ticable interference with traffic on the elevated structure and on the streets below. The improvement aggregated about fifteen miles of such work requiring the fabrication and erection of about 50,000 tons of structural steel at an estimated cost of $8,000,000. The Man- hattan Elevated Railway Company decided to employ certain responsi- ble contracting companies to do this work on the basis of cost plus fifteen per cent. This was made necessary on account of the intimate relation of the work to be done to the operation of the elevated rail- ways and the safety and convenience of the public. It is evident that it would be extremely difficult, if not impossible, to have prepared a sat- isfactory contract and specifications in order to have arranged for a public letting, and quite impossible to have provided for safe and sat- isfactory operation and, at the same time, to have secured reasonable bids by the ordinary method of competitive bidding. § 116. Contracts for Cost Plus a Fixed Sum. — In recent years the objection to the cost plus a percentage form of contract has been somewhat reduced by changing the basis from a percentage to the cost plus a fixed sum. By this form of contract, the contractor cannot profit by any increase in cost, but on the other hand will secure the greatest returns to himself by the least expenditure of time and money for the owner. This plan eliminates certain objectionable features of the percentage form of contract but does not eliminate the inefficient methods and unsatisfactory labor conditions. § 117. Contracts for Cost Plus a Variable Premium. — Another form of contract has been used to some extent in the last ten years. Cost— Plus Contracts 181 Under this form of agreement, the contractor undertakes to complete the work for a fixed sum and in a definite time. In addition to this sum, he is to be paid a stated premium which is reduced or increased, accordingly as the actual cost and time of completion are greater or less than the stipulated costs and time of completion. The advantage of this form of contract is that the owner can de- termine the final cost almost as closely as under the lump sum contract. If the cost of the work is less than the estimate, he is benefited to the extent of one half of the amount saved; while the other half is paid to the contractor as an extra premium earned. If the cost of the work increases above that of the estimate, half of the additional cost is paid by the owner and the other half is deducted from the contractor's pre- mium. If the work is completed in advance of the fixed time, the con- tractor receives a certain agreed sum per day for the time saved ; and if completed behind time, a corresponding deduction is made in the premium paid. The principal objection to this form of agreement arises from the possibility that the estimated cost may be high and the time of completion too great, under which condition the contractor may secure an unfair premium by his ability to reduce the cost and time below his estimates. If, however, this form of agreement is put into competition with lump sum bids on the basis of the estimated cost and time provisions as has been proposed, an advantage may be se- cured by a reduced cost and by the unity of interests which should en- sue from this form of agreement. In a somewhat similar contract made in Boston, the agreement provided that the contractor should receive first the actual cost of the work plus ten per cent, of such cost. Upon the final completion of the work, the total cost plus the percentage was to be compared with the estimated cost made by the engineer, and provisions were made in the agreement, in case the estimate was unsatisfactory to the contractor, for a revised estimate by a board of three engineers. If the total cost of the work exceeded the estimated cost, then one fourth of this excess was deducted from the ten per cent, to be paid the contractor; and in case the work was less than the estimated cost, the contractor was en- titled to receive one fourth of the amount saved. The entire cost of small tools and supplies used was charged to the work, and the cost of machinery, tools and appurtenances purchased for and used upon the work, less their value at the end of the contract, was also included in the computed cost. There is no apparent reason why a contract under the above plans may not be satisfactory and may not be applied to the carrying out of 182 Day Labor and Contract Systems public works under open competition. This could be done by con- tractors stating in their proposals the percentage they would accept in addition to the actual cost of the work, with proper provision for addi- tions or deductions to be calculated on the basis above mentioned.

Public and Private Works. — The term ''public works" means works constructed for municipalities, counties, states, and na- tions, such as sewers, pavements, bridges, canals, river improvements, and other works constructed at public expense and under public con- trol. The term "private works" means works constructed by private parties, partnerships or corporations such as buildings, hydraulic plants, railroads, and other works constructed by private capital and under private control. The procedure of authorizing expenditures, fixing contract requirements, advertising for proposals, receiving bids, letting work, consummating contracts, and interpreting contracts differs ma- terially in private work from that required in public work. The laws governing the making and letting of contracts for public works have been framed to obviate collusion and fraud, and their re- quirements must be observed in order that a legal contract may be made. Public works must usually be let only after advertising, and to the "lowest responsible bidder." State laws sometimes require public work to be advertised for a certain length of time, in certain ways, and to a certain extent, previous to the letting of the contract. The legal or charter requirements for advertisements are imperative to secure the validity of the contract. Where the law provides that -the contract shall be given "to the lowest responsible bidder giving adequate security," such bid cannot be arbitrarily rejected. Any act whereby a higher bid- der is made to appear the lowest, will invalidate the contract.^ The contract to be valid must be executed without alteration in plans, specifications or time;^ but when laws do not require contracts to be awarded to the lowest bidder, alteration may be made in con- tracts before they are executed. Void contracts cannot be legalized by public officers but may be ratified by legislative action.^ Any reasonable requirements imposed 1 Walt's Engineering and Architectural Jurisprudence, sec. 140. 2 Ibid, sees. 141, 142. « Ibid, sees. 141, 142. Public and Private Work 185 on bidders to secure or facilitate comparisons of bids lie within the dis- cretion of the official letting the work, and such requirements must be observed. When a certified check or other security is required with a bid for public work, and through error a mistake has been made, such security must be forfeited and public officials have no authority to waive such forfeiture. Determination of responsibility is discretionary but must be exercised in good faith. Acceptance by a public official may not, and usually does not, complete an agreement until such acceptance is formally ratified by the governing body. In the preparation of the contract and specification, it is necessary to keep in mind the distinction between public and private works. Con- tracts and specifications for public work must be so drawn as to allow opportunity for intelligent competition. Provisions made for payment for the performance of extra work are legal * if the work designated is actually extra work. If however the work designated is a material part of the work which it is known must be done payment so made will be illegal. In the case of Moyn- ahan v. Birkett, the so called extra work was in reality an essential and known part of the work to be done and the court states : "When the law provides that the work must be let to the lowest responsible bidder, any clause in the contract which fixes the price for extra work without bids on that subject is illegal, and payments at rates specified may be enjoined at the suit of a taxpayer." ^ In many cases the bid of con- tractors on their own plans may be illegal under similar circumstances, as public bodies are usually empowered to determine the lozvest and not the best bid.^ In numerous cases however bids on alternate paving specifications have been declared legal,^ although such decision seems illogical and based on a misapprehension of the principles of competi- tion.^ In the execution of public work, no departure from the contract requirements can be legally permitted, but the specifications must be *Abells V.

The public is not bound by principles of justice and equity and is not interested in the contractor's success or failure, and any changes which are made to benefit or assist the contractor are apt to be misconstrued and criticised and may involve serious consequences to the engineer. Private work, on the other hand, may be advertised or it may be let without advertisements, by public competition, by competition between selected parties or by agreement with a single contractor, as the owner or corporation may elect. In a private contract a verbal acceptance of a proposal may consummate the contract, and awards should there- fore usually be made subject to the making of a written contract, if such written contract is desired. In private work, other conditions and requirements are also radi- cally different from those for public works ; alternate bids, modifica- tions of requirements, adjustments and betterments that conditions seem to require in carrying out the work in hand may be made when- ever the parties to the contract agree. Rights may be waived, obliga- tions cancelled, and extra compensation granted, whenever it appears that such actions are warranted by justice and equity or by expediency. It is true that in public contracts, the legal requirements have been sometimes ignored or neglected, and no serious consequences have fol- lowed. Many such contracts which were invalid have been made and the works completed and paid for, even in some cases where there has been wilful neglect, dishonest intent and collusion and fraud. This has been due only to the fact that the question of validity has not been raised in court. In other cases, honest errors, due to a mistaken conception of legal requirements, not well established by court decisons, have resulted in heavy losses and sometimes in financial failure to contractors who have honestly and conscientiously entered into otherwise fair and reasonable contracts for the performance of public works. The risk of ignoring legal requirements is too great, and no con- tractor should enter into a public contract which is not clearly legal in every detail. In the preparation of contracts for public works, it is therefore evident that the engineer is in equity bound to see that his designs and specifications are especially definite, full and complete, and as the re- requirements of the contract cannot be legally waived, especial precau- tion should be taken to see that they are fair and reasonable. The contractor, on his part, should ascertain either personally or through attorney 'that all legal requirements have been complied with ; Public and Private Work 187 that the ordinance or order authorizing the work has been legally passed; that the work has been legally advertised; and that the con- tract and specifications fulfill all legal requirements. Ignorance of the law excuses no one, and in doing business with the public a knowl- edge of all requirements is assumed by the court and is neglected at the peril of the private citizen. § 1 19. Negotiations for Construction Contracts. — The negotia- tions which are necessary prior to the consummation of a construction contract will vary in kind and formality wi th the nature of the work to be done. Where the party letting the work is a private person or cor- poration, such negotiations may take any form desired. Usually the owner will invite bids based on specifications more or less complete, with or without some proposed contract form. The request for pro- posals may be advertised or notices may be sent to such parties as may seem available for the work in question. The purpose of soliciting more than a single bid for either public or private works is to secure for the public or the owner the advantages of competition and the right to select a proposal which is advantageous. By such competition, contractors are induced to make close estimates, the amounts of which are usually dependent upon the amount of similar work available, and the state of the market for labor, materials, etc., to be furnished. Competitive lettings, if honorably carried out by all parties, are usually the most desirable methods of letting construction contracts. Where, in private work, the value of the work to be done, or the materials to be furnished, is well known, it may prove more satisfactory to let the work without competition to a responsible con- tractor known to do satisfactory work or to furnish the supplies, material or machinery especially desired, and at a mutually satisfac- tory price. Satisfactory results from private lettings are dependent on honorable dealings, and this method is perhaps open to greater oppor- tunities for dishonesty when the work is let by a third party (the engi- neer or some other official), and not directly by the owner. § 120. Dishonesty in Competitive Letting. — The competitive letting of construction contracts is also open to dishonest practices. Contractors may combine with each other with the intention of securing high prices under apparent competition, where no such competition actually exists. Apparent competition has been sometimes secured by more than one bid by apparently different but actually the same par- ties. If the two bids submitted by the same party were both lower than those submitted by other bidders, the lower bid would be withdrawn on 188 Works Constructed under Contract account of alleged mistakes, allowing the higher bid to stand and thus securing the contract at a price greater than the lowest price at which the contractor was really willing to undertake the work. This with- drawal of a bid could be formerly accomplished on the common law right to withdraw or revoke an offer at any time before its acceptance. To prevent such withdrawal, bidders, especially on public works, are now usually required to accompany their proposals with certified checks or bidder's bonds, which they agree to forfeit if they revoke their pro- posal. Where negotiations are carried out between private parties and responsible contractors, the requirement for a check or bond to accom- pany the bid is seldom made, as in such cases proposals are usually made in good faith and will be carried out if accepted. Contractors also sometimes agree among themselves on the party to whom the award shall be made. The lowest bid, sometimes at an exorbitant price, and the contractor to submit it will be agreed upon, and other contractors will either withdraw or submit higher bids in or- der to simulate competition. Such combination can be prevented only by a knowledge of the real value of the proposed work. These com- binations are illegal and, in case of public work, may in fact be crimi- nal. If they can be proved, they will invalidate a contract so secured, whether public or private. Occasionally competitive bids are invited only for the purpose of compelling a favorite bidder to reduce his bid to the lowest possible amount and with no intention of utilizing the bids so submitted, except as a means of forcing the favorite bidder to reduce his bid. It is evidently unjust to request proposals from bidders whose bids will not actually be considered, and thus cause a needless expenditure from which they can receive no consequent possible benefit. Any en- gineer or business man pursuing such tactics will soon find himself in ill repute among responsible contractors and his future attempts at securing satisfactory bids greatly embarrassed. The engineer should know no friends nor favorites among the bidders in the letting of any work to be done under his specifications and should strive to award the contract to the lowest and best bidder in all cases. § 121. Restricted Lettings. — For private lettings, proposals may be restricted to those persons or companies known to be most reliable or capable, and others whose capacity or capabilities may be question- able may be excluded. Where the knowledge of those letting the work is sufficient to justify such discrimination, such a selection seems de- Restricted Lettings 189 sirable, as it greatly simplifies the selection of a responsible contractor and prevents a needless expenditure by those parties who might other- wise desire to make proposals which would, for the reason mentioned, receive no serious consideration. Ethically only such bidders should be included in the request for proposals as the owner is willing to con- sider in awarding the contract. To secure proposals which are competitive, they should all be based upon plans and specifications which should be as specific and in as great detail as practicable, and all available information should be furnished to each bidder alike. Any additional information that will give the advantage to any favored contractor is an injustice which should be strenuously avoided ; and when such information is furnished by an official, without the knowledge of the owner, such action is dou- bly dishonest and operates as an injustice not only to other contrac- tors but also to the owner who under such conditions has not the real competition to which he is justly entitled. So far as practicable, the controlling factor of the letting should be the lowest bid. This cian often be accomplished by making the specifications so complete and definite that other differences shall be obviated. If any owner desires to confine his purchase to a single company, he should inform himself, either directly or through his engineer, by proper inquiry and investigation so that he may feel that he possesses the requisite knowledge of values to undertake negotiations with such company without putting others to needless expense. § 122. Securing Low Bids. — It is the reasonable desire of every engineer and owner to secure bids for the proposed work to be let un- der contract at as low a figure as can reasonably be made, and at the same time assure good material and good work. To accomplish this, the ideas of the parties who are asked to undertake such work must be understood and appreciated, and if requirements are made which are unnecessary and add to the expense or increase the hazard and consequent chance for extra expense, they should be eliminated. The wishes of the contractor in these matters should not be ignored but should be considered so far as practicable, for aside from the question of equity, there is the question of expense, which will always appeal to the owner. Mr. Richard Morey, of the Morey-Faulhaber Construction Com- pany, expressed his ideas on how to get low bids from good contrac- tors, in a paper before the St. Louis Railway Club, as follows : 190 Works Constructed under Contract "1. Give full and detailed information as to the work, all dimensions, quantities, classes of materials; everything that can possibly be used to fig- ure costs. "2. Ask for bids on as many units as can be applied to the work. This may increase slightly the office work, but it will reduce costs. To use. grading as a simple example, a contractor will bid lower and the work will cost the railway company less, if the proposals are made so as to separate bids on excavation hauled, excavation wasted, embankment borrowed, over- haul with a short free haul and all possible classifications of material. To the contractor this means that uncertainties are reduced to one or two items and that he will be paid for just what he does. To the railway com- pany it means an elastic contract that readily covers the inevitable changes of line or plans, and that the company pays for just what it gets. "3. Rewrite some of the clauses in the contracts and specifications, par- ticularly those which applied to former conditions, but do not fully cover present ones, and, especially, some of them which have grown from inter- lineations made from year to year in your printed forms. "4. Recognize the relation between the responsibility of the contractor and the requirements for the bond and the retained percentage. At the time the contract is signed, and the responsibility of the contractor is measu^'ed by the full amount of the contract, the railway company is satisfied with a bond; later, as the work is near completion and parts of it even in use, the railway company still has the bond and also the retained percentage and the con- tractor's responsibility has become insignificant. "5. Give us as inspectors men whose knowledge of the work at least approaches that of our foremen. "6. Give us our full quantities on our monthly estimates and then see to it that the vouchers made to cover those estimates move promptly through the auditor's office to the treasurer." 9 § 123. Suggestions of American Society of Engineering Con- tractors. — A committee of this society submitted a report in January, 19 1 3, in which the follovv^ing desirable requirements for pubhc con- tracts were expressed : "1. The committee thinks it impossible to submit a complete form to cover all phases of all engineering contracts, but a work of much value can be done by adopting some general principles and formulating them so that they may be made a part of substantially every contract. "2. Every condition, of whatsoever character, by which the parties are to be bound should be submitted to bidders as part of the specifications on which they bid. The contract to be signed should be annexed to the specifications. In this way the bidder is not liable to be surprised by new conditions appearing in the contract submitted for his signature after his bid has been made and accepted. "3. The greatest vice of contracts is uncertainty. In adopting any form of contract or specifications every effort should be made to secure exactness of definition of the rights and duties of both parties. 9 From the "Proceedings of the St. Louis Railway Club." Desirable Requirements 191 "4. Recognizing the impossibility of foreseeing every emergency, some authority must be devised for the determination of either unexpected physi- cal conditions or unforeseen ambiguities in the contract. "5. The first requisite to this is promptness, so that the work may proceed. This doubtless requires that all disputed questions shall be pri- marily settled by the engineer present on the work. "6. While the engineer is the best-fitted person to reach a prompt de- cision, his relation to the owner unfits him for an impartial decision. There must, therefore, be some provision for an appeal to an impartial tribunal and final settlement of all disputes by it. "7. Disputes should, as far as possible, be settled as the contract progresses, so that the parties can know how they stand. To this end all matters of dispute should be reduced promptly to writing and all appeals from the engineer's decisions should be promptly taken. "8. Each party should assume full responsibility for his own share of the contract. "9. This involves the assumption, by the owner, of responsibility for the local conditions and for the borings or other explorations of the site. The contractor should bid on guaranteed local conditions, with an increase or reduction of price for variations from these. The locality belongs to. the owner, and the contractor should not be obliged to gamble on it. "10. The principle also requires that a contract should not both provide the exact details of construction and guarantee the result. If the con- tractor is to do the work according to exact plansi furnished him by the owner, the owner should take the responsibility for the result. If the con- tractor guarantees the result, he should be free to adopt his own methods of construction. "11. The contractor, especially when bound by a time limit, should be given the utmost freedom as to the order and manner of doing the prescribed work. "12. Definite provision should be made for the assertion, in writing, of demands made by either party varying from the normal contract price. The contractor should give prompt notice of a claim for extras and the owner of a claim for a decrease or for the assessment of damages. "13. Some rule should be prescribed for the owner's protection in case of delay on the contractor's part, either by a right to annul the contract or to take over the work, in whole or in part, or to deduct actual or liquidated damages. The subject is one of great difficulty and needs most careful consideration. "14. The contractor should be protected from loss by delay of the owner or the owner's other contractors, and provision made for settling such losses without suit where possible. "15. What is the proper amount of retained percentages? What should be the maximum part of the contract price to be retained until final payment? Differences of opinion should be adjusted and a uniform rule adopted. 192 Works Constructed under Contract "16. Material men insist that the contract bond should provide for pay- ment for materials and labor. This leads to greater security to the material men and consequently lower prices. But it is an unnecessary cost to con- tractors of established credit. This subject needs the views of both sides. "17. Some contractors and engineers maintain that the contra coal, with freight allowed from the Chapin mine to Rockford, Illinois, and all payments shall be made on or before the fifteenth of the month for all coal delivered during the preceding month.

Written Executory Contracts. — The written executive contract may include all forms from the simple contracts, such as shown above, in which no technical specifications are included and the general conditions are few, to the elaborate contract necessary for the more complicated technical work that requires the preparation of numerous general conditions and many general and detailed specifications. In every case the contract or article of agreement should include, besides all requirements for a valid contract (see Sec. loi), 1. Parties to the contract (names, description, residence, etc.). 2. Subject matter: Promises to be performed (work, materials, etc., to be fur- nished or done). Counter-promises (payments to be made). 3. Time of performance. 4. Date of contract. 5. Signatures. These matters are usually written in a more or less formal manner with certain set forms of introduction, declaration and closure, which are, however, legally unessential. The essential features of an agree- ment are simply those features necessary to indicate clearly the nature and extent of the obligations assumed by all parties concerned. In many cases the purchaser may not be acquainted with the ex- act nature of the material or supplies which can be purchased from a certain miner, manufacturer or dealer, and may desire to secure ma- terial or supplies of a certain and definite kind, or he may desire cer- tain work done, machinery furnished or structures built in a certain 226 Contracts way, for a certain purpose, or to accomplish certain results. There may also be certain responsibilities which the owner desires the con- tractor to assume, and the contractor may be asked to agree to certain conditions in regard to supervision, inspection, etc., and may also in- clude certain further conditions in regard to the manner and methods of conduct of the work, and certain conditions in regard to the financial arrangements, payments, etc., may be desired. In order that the owner may secure a definite offer for the under taking, he should prepare a form of agreement which should contain all the conditions and specifications which may be necessary to describe clearly the undertaking and make his wishes in the premises definitely and distinctly manifest. In case these conditions and specifications are brief, they may be written into the form of agreement but where they are elaborate and involved they may better be included by reference in the agreement and be prepared as one or more separate and distinct paper which may be included under several heads such as : General conditions, General specifications, and Specifications for In any event the agreement either within itself or together with the attached papers should explain exhaustively all matters concerning the work and material, and should contain all covenants regarding supervision, conduct of the work, responsibility of either party, pay- ments, guarantees and all specifications relative to the methods to be employed in its performance, and the materials, supplies and appliances to be furnished or used in the construction. Clearness, explicitness, inclusiveness, brevity, and proper arrangement are ends to be attained in their preparation. That and only that which it is desirable to cove- nant or to specify, should be included, and all covenants and specifica- tions should be stated in the shortest and clearest terms compatible with a proper and clear understanding of the matter intended to be set forth. The complete form of agreement, including all covenants and specifications, forms the basis for the negotiations for a contract. While in important work the form of agreement is usually prepared by one party to the contract without consultation with the other party, who in general is unknown, it must be so prepared that all its clauses will be acceptable or accepted by the contractor or no contract can be made without its modification. Frequently the negotiations are preceded by an advertisement, the purpose of which is to call the attention to the undertaking, and often further information is given to those who desire to become contractors Written Executory Contracts 227 through information included in a paper entitled ''Instructions to Bid- ders/' or ''Information to Bidders/' and, lastly, an offer to perform the undertaking may be made on a prepared form by which the various bidders offer to perform the undertaking under the proposed agree- ment, at a certain price or at certain prices which, being submitted in the same way, become comparative, unless other factors besides price, such as difference in quality of material, in workmanship, or in experi- ence and reliability, become of importance. When a satisfactory pro- posal is received, it is accepted subject to the making of a written con- tract, in which event the "Advertisement/' "Instructions/' "Proposal/' and "Form of Agreement/' "General Conditions/' "General Specifica- tions/' and "Detailed Specifications" are united, and when signed, con- stitute the contract. In some cases the drawings are also attached to the contract, but in most cases they are included by reference only. § 144. Form. — All agreements upon which bids are to be re- quested and contracts are to be based should be complete and should be so arranged as to lead to the utmost clearness in the understanding of what is necessary in making out proposals, submitting bids, enter- ing into the contract, and executing the obligation. The arrange- ment should also be such as will facilitate ready reference to each and every point which is therein mentioned. Completeness is necessary on account of the fact that an acceptance of an offer, to legally consum- mate a contract, must be identical with the offer, and the fulfillment of an offer cannot be enforced if it involves the signing of a contract containing other and more onerous conditions than those on which the offer is based. Hence, if the papers are entirely complete and available at the time the proposal is made, the acceptance will usually consummate the contract. It is therefore also desirable that an ac- ceptance be made provisional on the final consummation of the written contract. A systematic and orderly method in the preparation of all the papers in connection with any contract is advisable, for by adopting such methods the ground can be completely and systematically covered and no details omitted. To facilitate uniformity and to prevent omis- sion and misunderstanding, the arrangement of papers should usually be such that by the filling of blanks, the attachment of such supple- mentary specifications as the contractor may be required to furnish, the signing of the agreement, and execution of the bond, the contract can be consummated. The agreement often includes the "General Conditions," and even the "Specifications." The general conditions are sometimes, and the 228 Contracts specifications often, written separately and confined to their own par- ticular subject. The incorporation of either the general conditions or the specifications into the agreement is not essential, as a reference in the agreement to any papers, and their attachment thereto, make them equally a part of the contract. This is also true of the ''Adver- tisement/' ''Instructions/' "Proposal/' etc. Even a proper reference to these papers, sufficient for their identification, is sufficient to make them a part of the contract, though unattached, but identification is com- plete if they are attached. A reference to the drawings, sufficient for identification, is all that is necessary, and the attachment of such draw- ings to the contract is unusual except in the case of standard machin- ery where photographs and illustrations may either be attached to or accompany the contract. These papers when printed are often printed and bound in the ordinary legal document form, that is, bound at the top and opening from the bottom. The pamphlet form, however, is largely used and is much handier for reference and much to be pre- ferred to the legal form. When the papers are printed, and the legal form is used, the matter should usually be printed on only one side of the paper, as this arrangement ofifers greater facilities for examina- tion and use. In the pamphlet form, both sides of each sheet may be utilized, the papers being therefore less bulky. In the arrangement of the matter in either case, the following order may be used : Title: Front page of cover. (Description only.) Advertisement: Second page of cover. (Sometimes printed on the back of the cover, and generally omitted in private con- tracts.) Table of Contents (or Index.) Estimate of Amounts of Work to be Done. (Not essential, but often desirable.) Instructions to Bidders. C Often included under either heading; Information for Bidden ( not used in simple contracts. Form of Proposal. Form of Bond with Proposal. (If one is used.) Agreement. General Conditions. f -r-- i r . r .1 ^ , ^ .- . J Either as a part of or separate from the General Specvncations.'S . . ^ T^ ^ -7 ^ c^u -j: ^- fc^rm of agreement. Detailed Specifications. L Form of Bond zvith Agreement. (This may be, and usually is, a separate instrument.) Form for Filing. (Back page of cover.) Form 229 When the advertisement is printed on the back of the cover, it should be so arranged that when the document is folded, the form of filing will be on one side and the advertisement on the other side. Sometimes the printed advertisement is cut from the paper in which it appears, and is fastened to the Form of Contract, which answers every purpose. The bond to accompany the contract may be made a separate in- strument and not included under the same cover as the other papers. This is certainly as well, as reference to the bond is seldom necessary, while the agreement and specifications are generally required for fre- quent reference. § 145. General Clauses for Agreement. — When the general con- ditions are not included in the form of agreement it should usually include only those important covenants that define, and fix the direct relation of the parties to each other in the most important matters. The following are suggested as the headings under which the datx for an agreement may be prepared, subject to such modification as may be found desirable on different classes of work : Outline for Agreements 1. Introduction of agreement and date of same. 2. Designation of parties, name, description and residence. 3. Declaration of agreement, parties and legal representation. 4. Exhibits as attached conditions, specification, drawings, etc. 5. Time of beginning and completion. 6. Liquidated damages. 7. Payment. 8. General provisions, bond, etc. 9. Final clauses, date or reference to date, signatures, seal, wit- nesses and acknowledgment. Discussion of Articles of Agreement I. Introduction to Agreement and Date of Same. — No specific form of introduction is required by law. A great variety of forms are in use among which may be noted the following : a. "This agreement made and concluded this day ot , A. D. by and between ." b. "This contract made and concluded by and between 230 Contracts The date on which a contract was made often becomes of much importance and should, therefore, be duly recorded/ In form "b" the date is usually written at the end of the contract. 2. Designation of Parties^ Names, Residences and Description of Same. — No specific form is required for this particular clause of the agreement, but the parties to the contract should be so clearly desig- nated that their residence and their relations to the contract will be fully understood. The following form is commonlv used : "By and between the City of Madison, a municipal corporation in the County of Dane, State of Wisconsin, represented by the Mayor and City Clerk, party of the first part, and The Blank Construction Company, a corporation organized and existing under the laws of the State of Illinois with its principal office in the City of Chicago, County of Cook and State of Illinois, represented by John Doe, General Manager, party of the second part." When a contract is made by a corporation through its authorized representatives or agents, the relation and authority of the representa- tives or agents should be clearly stated in order that the authority may be properly investigated and clearly understood, and in order that the personal liability of the representatives or agents may be avoided.^ "By and between the Mayor, Aldermen, and Commonalty of the City of New York, acting by and through the Aqueduct Commissioners, by virtue of the power vested in them by Chapter 490 of the Laws of 1883, of the State of New York, parties of the first part, and ." The following example used by the Metropolitan Water and Sew- erage Board differs somewhat in form from the preceding : " , and the Metropolitan Water and Sewerage Board duly constituted, and appointed under and according to the provisions of Chapter 168 of the Act of the Legislature of the Commonwealth of Massa- chusetts of the year 1901, herein acting for the Commonwealth, and without personal liability ta themselves, and hereinafter designated as con- tractor agree as follows:" As different states have different statutory modifications of the common laws, it is important that the residence of both parties to a contract be stated. If the parties to a contract reside in different states, the place at which the contract is made will ordinarily fix the laws under which the contract is to be interpreted. This matter may be definitely fixed, however, by including in the agreement a statement that: "This contract is to be regarded as a Wisconsin (or such other state as may be desired) contract." 1 See Wait, Engineering and Architectural Jurisprudence, sec. 59. 2 Wait, Engineering and Architectural Jurisprudence, sees. 29-39. General Clauses 231 The term "party of the first part" conventionally applies to the person who contracts to sell, lease, or have performed the subject mat- ter of the contract. The term ''party of the second part" convention- ally applies to the person who agrees to take or to purchase the article or to perform the contract. The use of these terms is frequently avoided by using instead some designation for the parties, such as "the company," "said contractor," "said owner," "said board," "said manufacturer," etc., etc. 3. Declaration of Agreement — Parties and Legal Representatives. This clause may also differ greatly in form. The following is a com- mon form : "Witnesseth that for and in consideration of the payments and agree- ments hereinafter mentioned to be made and performed by said Party of the First Part and under the penalty expressed in a bond, bearing even date herewith, the said party (or parties) of the Second Part agree with the said Party of the First Part at his (or their) own proper cost and expense to do all work and furnish all material called for by this agreement in the manner and under the conditions hereinafter specified." Provisions for the death or incompetency of either party to a con- struction contract are usually provided for by definitely including "the heirs, executors, administrators, or assigns" of a person, or the "suc- cessors or assigns" of a corporation.^ Example — "The said Party of the Second Part does hereby, for himeelf, his heirs, executors, administrators or assignees, promise and agree with the said Party of the First Part, its successors or assigns, at his own proper cost and expense, etc." When a contract is made for the personal skill or professional knowledge of the contractor, it will be discharged by his death, other- wise the legal representative of the contractor is liable under it and reference to "heirs, administrator or executor^' is unnecessary. Their mention in the contract is, however, evidence that the contract is not of such a personal character. In the same way the term "assignee" should be omitted either when "personal skill" is contracted for or when the agreement includes clauses prohibiting an assignment of the con- tract.* 4. Exhibits. — When the general conditions and specifications are not included in the form of agreement, a paragraph must be introduced 3 Ibid, sees. 7-12. 4 Ibid, sees. 13-16. 232 Contracts in the agreement by which it is stipulated that such conditions, specifi- cations, etc., as may be essential are to be attached thereto and made a part thereof. For example : "The parties to this agreement hereby stipulate that the following ex- hibits, which are attached hereto, are made a part hereof as though written herein : The advertisement marked "Exhibit A." The instruction to bidder marked "Exhibit B." The form of proposal marked "Exhibit C." The general condition marked "Exhibit D." The general specification marked "Exhibit E." ^ The detailed specification marked "Exhibit F," The contract drawings marked "Exhibit G." Exhibit G shall consist of drawings described and numbered as follows: Here should follow the title and number or other distinctive mark of the various drawings. When the general conditions are included in the form of agree- ment and the specifications are not, the clause concerning the exhibits makes them a part of said agreement, such as the following : a. "All work shall be done and all material furnished in strict conform- ity with appended advertisement marked 'Exhibit A,' instructions to bid- ders marked 'Exhibit B,' and specifications marked 'Exhibit C,' which are appended hereto and are hereby made a part of this agreement,' or b. "And it is further expressly agreed that the said excavation shall be made and said masonry shall be built, and all grading and filling shall be done, and all work, labor and material to be done and furnished under this contract shall be done and furnished strictly pursuant with and in conform- ity to the specifications hereto annexed which are made a part of this agree- ment." 5. Time. — When the general conditions are not included in the agreement and the time of completion is a matter of considerable im- portance, one of the articles in the general form of agreement is com- monly devoted to this subject, although the further general conditions and stipulations in regard to delays, extension of time, and forfeitures are placed in the general conditions. The article in the form of agreement may be essentially as fol- lows: The contractor further agrees to begin work within • days from the date of this agreement and to prosecute the work so that it will be en- tirely completed on or before . The maintenance of a greater progress in this work which will result in its completion within a specified time, is an essential feature of this contract, and the contractor agrees to do all General Clauses 233 things and to take all necessary precautions to insure the rate of progress and the time of completion as stated and defined in this agreement and in the attached specification. 6. Liquidated Damages.^ — The liquidated damages to be paid by a contractor for delays in the completion of the work undertaken by him to be completed in a given time under the stipulations outlined in paragraph 5 are usually of sufficient importance to be included as one of the articles in the form of agreement, even in cases where the gen- eral conditions are made a separate exhibit of the contract. This may be done by stipulations essentially as follows : The party of the second part agrees to pay the party of the first part as liquidated damages the sum of dollars per day for each and every day that he delays the completion of the entire work to be done under this contract; and the party of the first part shall have the right to deduct the amount of any such liquidated damages from any moneys due or which may become due to the party of the second part under this contract, and to collect from the party of the second part and his sureties any excess of such liquidated damages over and above the amount that would be otherwise due the contractor. 7. Payments. — The payments to be made under an agreement are provided for in various ways. In some cases the form of proposal, after being accepted, is attached as an exhibit to the agreement, in which case it is stipulated in the agreement that payments shall be made in accordance with the prices set forth in the exhibit and in con- formity with the general conditions and specifications attached to the agreement. In other cases, a schedule of unit prices and estimated quantities is included as one of the articles in the general form of agreement. This is apparently done for the reason that the payments are a most important factor and that such importance warrants their insertion into the agreement itself. These two forms are shown in the following examples : (a) For and in consideration of the faithful performance of the con- tract by the party of the second part in full accordance with the plans and specifications, and with the stipulations herein contained or attached hereto, the party of the first part agrees to pay to the party of the second part the prices set forth in the form of proposal, which is marked ''Exhibit C" and attached hereto and made a part hereof. Said payments shall be made in accordance with the general conditions and specifications attached hereto. (b) For and in consideration of the faithful performance of this con- tract by the party of the second part in full accordance with all of the pro- visions of the same as set forth in this agreement and in the various ex- 5 See also Paragraph M, Sec. 153. 234 Contracts hi bits attached hereto, the party of the first part agrees to pay to the party of the second part, in the manner and at the times hereafter set forth, and at the rates mentioned and described in the following schedule of unit prices, to wit: Schedule of Unit Prices Item Class Unit of Quantity Unit Price 8. Provisions for Bond, etc. — The provisions for bond are some- times included under paragraph 3, as shown in the examples given therein. In other cases they are stipulated in an article at the end of the form of agreement, essentially as follows : ^'Contract and Bond. — It is further agreed by the parties to this contract that this contract shall be executed in triplicate, one copy being retained by the party of the first part, one to be delivered to the party of he second part, and one to be delivered to the chief engineer. "The party of the second part further agrees to execute a bond in the sum of dollars for the faithful performance of the work and in the form provided for that purpose, and it is agreed that this contract shall be void until such bond is signed, delivered, and approved by ." 9. Final Clause and Signatures. — In the final clauses and signa- tures it is important to see that all legal requirements are duly com- plied with. In the case of corporations, either public or private, the rights of the parties signing the agreement for such corporatons should be carefully determined in order that the agreement may be a legal and binding obligation on such corporation. In some cases a seal is de- sirable or essential; in other cases witnesses to the signature are nec- cessary ; and in still other cases, acknowledgment before a notary pub- lic is required. "In witness whereof the parties to these presents have hereunto set their hands and seals the day and date first above written." Where the date is not inserted in the first part of the contract, the final clause should be as follows : "In witness whereof the parties to these presents have hereunto set their hands and seals this day of , A. D. 19 — ." 10. Importance of Mutuality. — It is exceedingly important to keep in mind the necessity of mutuality in the preparation of a contract. Clark says, "Mutuality of engagement is necessary, and, if the condi- tion or contingency produces want of mutuality, the consideration is insufficient. Both parties must be bound or neither is bound."* In the preparation of contracts attempts are sometimes made to reserve to the parties letting the work, unfair privileges which undoubt- *Clark on Contracts, 3rd Ed. page 145, General Clauses 235 edly invalidate the contract, as would be found should such contracts reach the courts. Fresuently such unfair stipulations are used and re-used, since their validity may not be questioned. Such continued use is no assurance of their validity. Such unfair stipulations tend to increase the contract price of the work and are undesirable both for this reason and on account of their lack of equity. A contract made by the City of Ft. Worth Texas, for certain public improvements and containing such clauses was declared void ]>y Judge E. R. Meek of the Federal Court, Northern District of Texas. The clause in this contract was as follows : "And the party of the second part hereby further agrees that if on account of any restraining litigation or legal proceedings against the party of the first part, or on account of lack of funds to carry on the work, or if for any reason it may appear to said City to be necessary or for the interest of the City of Fort Worth to suspend work entirely, and to cancel this contract wholly and completely, then the said city shall have the power to at any time cancel this contract wholly and completely, although the contractor may not be in default, and the party of the second part hereby specially agrees that such cancellation, if done, shall not entitle him to any claim for damages, or for prospective profits on any work remaining to be done; but if the contractor be not in default, he shall be paid in full for all work done, and for all materials delivered in accordance with this contract, up to the time of notice of such cancellation, and there- upon shall be released from all obligations hereunder for the completion of this contract." It was pointed out that while the City reserved this right to cancel the contract, the contractor had no such right ; that the clause, if ad- hered to, and acted upon by the City when the work was constructed only in small part, might work great injustice on the contractor inas- much as all the "overhead" expense necessary in getting the work under way would have to be borne by him, and that therefore the contract was void on account of lack of mutuality. CHAPTER XIV GENERAL CONDITIONS OF THE CONTRACT § 146.

Definitions. Interpretation of Phrases and Definitions or Other Similar Title. — It is desirable to include in the general conditions definitions of the various phrases or terms used throughout the contract, such as ''Party of the First Part," 'Tarty of the Second Part," "Contractor," "Engi- neer," "Chief Engineer," "Inspector," "Owner," "Company," "City," and any other words, terms or abbreviations which are not otherwise fully defined. This may be done by inserting paragraphs descriptive of each title or terms as follows : "Whenever the word(s) or the expression 'Party of the First Part' or 'First Party' are used in this contract, it shall be understood as referring to (here describe the person, company or corporation enter- ing into the contract to have the same performed) " "Whenever the word 'contractor' or the expressions 'Party of the Sec- ond Part,' or 'Second Party,' are used it shall be understood to mean the per- son, persons, co-partnership or corporation who has agreed to perform this contract or to his or their legal representatives." "Whenever the word 'Engineer' is used in this contract it shall be un- derstood as referring to the Chief Engineer of the party of the first part, or such other engineer, superintendent or inspector as may be authorized by said first party to act in any particular." "Whenever the words 'Directed,' 'Required,' 'Permitted,' 'Ordered,' 'Des- ignated,' 'Considered Necessary,' 'Prescribed,' or words of like import are used, it shall be understood that the direction, requirement, permission, or- der, designation, or prescription, etc., of the Engineer is intended; and similarly, the words 'Approved,' 'Acceptable,' 'Satisfactory,' or words of like import, shall mean approved by, or acceptable or satisfactory to, the Engi- neer." § 149. Rights and Responsibilities of Ovv^ner. A. Inspection and Supervision. — Unless the owner is willing to assume responsibility for the negligence of the contractor and the re- sult ultimately to be accomplished under the contract, he must not im- pose his control of the manner and method by which the results are to be accomplished.^ The retention of the control of men and method by the owner de- stroys the relations of "Owner and Independent Contractor" and es- tabhshes the relation of "Master and Servant" or of "Principal and Agent." 2 The owner may direct as to the result of the undertaking, and may prescribe in the specifications and plans the method and manner of do- 1 Wait, Engineering and Architectural Jurisprudence, Sec. 651. 2 Ibid, Sees. 653 to 659 and Sees. 665 to 666. Rights and Responsibilities of Owner 239 ing the work. He may delegate the direction and supervision of the work to his authorized agent or agents, that is to his engineers, in- spectors, etc. In this case the contractor by accepting the contract, ac- cepts such methods and manner of doing the work as his own.^ Care should be exercised in including in the contract and specification, such requirements as are considered necessary as to the method of doing the work and as to the final result to be obtained, but any assumption of detailed control of manner or methods during the construction of the work should be studiously avoided, if, as is usually the case it is desired to fix the responsibility for the conduct of the work and for the results of the same, on the contractor.* Such supervision and inspection as may be desired must be speci- fied and described in the agreement. Any aid that the contractor is to furnish in connection with such inspection must also be clearly specified. "It is agreed by the party of the second part that the party of the first part shall he, and is hereby authorized to appoint from time to time such engineer, superintendent or inspector as the said first party may deem proper, to inspect the material to be furnished and the work to be done un- der this agreement and in accordance with the specifications therefor. The contractor shall furnish all aid and assistance required by the engineer, su- perintendent or inspector for the proper inspection and examination of the work and all parts of the same. The contractor shall regard and obey the directions and instructions of any engineer, superintendent or inspector so appointed when the same are consistent with the obligations of this agree- nient, and of the specifications attached hereto, or said contractor shall imme- diately appeal to the Chief Engineer for his decision, and shall respect such decision when so rendered." B. Right of Access and Collateral Work. — Unless otherwise pro- vided, an agreement for construction will ordinarily give the con- tractor full possession of the building, plant or field of operation, and if other contractors are to furnish material or to do work which may result in more or less interference, proper provision should be made in the agreement to retain this right. This stipulation should reserve the right of access to the work when such reservation is necessary or desirable. The reservations made, however, should not be such as may needlessly cause possible trouble or extra expense to the contractor. "The party of the first part reserves the right to enter the property or location on which the works herein contracted for are to be constructed or 3 Ibid, Sees. 660 to 664. 4 Ibid, Sec. 667, 240 General Conditions of the Contract installed by such agent or agents as it may elect for the purpose of con^ structing or installing such collateral works as said first party may de^re. Such collateral works will be constructed or installed with as little hindrance or interference as possible with the party of the second part. The party of the second part hereby agrees not to interfere with or prevent the performance of such collateral work by the agent or agents of the party of the first part, or to claim any extra compensation or damages by delays or hindrances which may be caused by the construction or installation of such collateral work." " and his engineers, agents or employees may, for any purpose, and other contractors may, for all the purposes which may be required by their contracts, enter upon the work and the premises used by the contracto'r, and the contractor shall provide safe and proper facilities therefor. Any differences or conflicts which may arise between the contractor and other contractors of in regard to their work shall be adjusted and determined by the engineer." C Changes, Alterations and Extra Work. — Provisions may be made for changes, alterations or extra work, but when so made, they may be exercised only in the manner and to the extent provided in the agreement.^ It should be noted, however, that any unauthorized changes in the contract will release the sureties on the contractor's bond, but that said sureties will not be released from the contract by changes which are duly authorized therein.^ "The said party of the second part further agrees that the said firfst party may make such alterations as said party may see fit in the line, grade, form, dimensions, plan or material of the work herein contemplated, or any part thereof, either before or after the commencement of the construction. "If such alterations diminish the quantity of the work to be done, they shall not constitute a claim for damages or anticipated profits on the work that may be dispensed with. If they increase the amount of work, such in- crease shall be paid for according to the quantity actually done, and at the prices established for such work under this contract; provided, however, that if said first party shall make such changes or alterations as shall make use- less any work already done or material already furnished or used in said work, that said first party shall recompense said party of the second part for any material or labor so used. No work shall be regarded as extra work unless it is ordered in writing by the Chief Engineer and endorsed by , and with the agreed price for the same specified in said order, pro- vided said price is not otherwise determined by this contract. All claims for extra work shall be made to said first party within sixty days after its completion, and, failing to make such claims within this time, all rights of the contractor for extra pay for such work shall be forfeited." 5 Wait, Engineering and Architectural Jurisprudence, sees. 551 to 571. 6 Ibid, Sees. 20, 21 and 576. Rights and Responsibilities of Owner 241 It is exceedingly undesirable to make changes in work which has been let under a contract, but in many cases such changes become ne- cessary on account of the development of conditions which have not, and, in many cases could not, be readily determined in advance of the beginning of the work. Radical changes, which materially affect the nature of the contract, either by a large increase or a considerable de- crease in the quantity of the work or by a change in its character are unfair and may result in serious injustice to the contractor. Such changes should, therefore, be limited in amount and such limits should be as small as safety will permit and should seldom exceed 25 per cent. If larger changes become necessary, they should be accomplished by the negotiations of a supplementary contract. "The said party of the second part further agrees that the said first party may make such alterations as said party may see fit in the line, grade, form, dimensions, plan or material of the work herein contemplated, or any part thereof, either before or after the commencement of the construction. It is agreed, however, that the change in the amount or quantity of any item shall not exceed twenty-five per cent. (25%) of the estimated amounts on which the bids were compared, and that if any changes are made to exceed this amount such changes shall be based on a supplemental agreement to be made therefor. "If such alterations diminish the quantity of the work to be done, they shall not constitute a claim for damages or anticipated profits on the work that may be dispensed with. If they increase the amount of work, such in- crease shall be paid for according to the quantity actually done, and at the prices established for such work under this contract; provided, however, that if said first party shall make such changes or alterations as shall make use- less any work already done or material already furnished or used in said work, that said first party shall recompense said party of the second part for any material or labor so used. No work shall be regarded as extra work unless it is ordered in writing by the Chief Engineer and endorsed by , and with the agreed price for the same specified in said order, pro- vided said price is not otherwise determined by this contract. All claims for extra work shall be made to said first party within sixty days after its completion, and, failing to make such claims within this time, all rights of the contractor for extra pay for such work shall be forfeited." D. Discrepancies and Omissions. — Where discrepancies are found between plans and specifications, which is frequently the case, in minor matters at least, the court ^will determine, if possible, the actual in- tention of the parties at the time of signing the agreement. Provisions may be and usually are made that the engineer may explain such dis- crepancies and may decide which shall prevail."^ 7 Wait, Engineering and Architectural Jurisprudence, sees. 225 to 235. 242 General Conditions of the Contract Any work or material not shown on the drawings or described in the specifications but which may be fairly implied as included in any item of the contract, shall be done and furnished by the contractor without additional charge therefor." Provisions may also be included in the agreement for the correc- tion of errors or omissions in matters or things which are fairly im- plied by the agreement, and the same rules hold as in the case of dis- crepancies. It is evident that the greatest care should be exercised to see that the plans and specifications fully agree and that discrepancies are prac- tically eliminated, also that the plans and specifications are complete. If care is exercised in these regards, the chance of serious discrepancies or omissions is remote. When plans and specifications are only gen- eral in character and show evidence of hasty or careless preparation contractors should refuse to bid upon the same if the engineer is em- powered by the contract to determine discrepancies and require omis- sions to be furnished at his discretion and without arbitration. These clauses should be so written as to prevent the possibilities of unjust claims for minor discrepancies or immaterial omissions but should not impose upon the contractor the expense of rectifying the mistakes of the engineer. "Discrepancies: Should there be any discrepancy between plans and spec- ifications for the work herein specified, the engineer shall define which is intended to apply to the work in hand, and the contractor shall be bound by such decision." "Omissions: Any work or material not herein specified but which may be fairly implied as included in the contract, of which the Chief Engineer shall be the judge, shall be done by the contractor without extra charge." "This agreement including the specifications, plans and estimates is in- tended to be sufficient to show all work to be done and material to be fur- nished hereunder. The quantities of the various classes of work and material to be done and furnished under this contract are approximate and are to be used only as a basis for estimating the probable cost of the work and for com- paring the proposals offered for the work, on a uniform basis. It is under- stood and agreed that the actual amount of work to be done and material to be furnished, under this contract may differ somewhat from these estimates, and that the basis for payments under this contract shall be the actual amount of such work and material done and furnished. "The contractor agrees that he will make no claim for damages, antici- pated profits or otherwise on account of any differences which may be found between the quantities of the various kinds of work and material actually done or furnished under this contract and the estimated quantities contained in this agreement. It is further agreed that it is the intent of this con- tract that all work must be done and all material must be furnished in ac- cordance witlj the best practice, and in the event of any discrepancies be- Rights and Responsibilities of Owner 243 tween the plans and specifications, or otherwise, or in the event of any doubt as to the meaning of any portion of the contract, specifications or plans, the engineer shall define which is intended to apply to the work, and the con- tractor shall he bound by such decision. Any work or material not shown on the drawings or described in the specifications but which may be fairly implied as included in any item of the contract, shall be done and furnished by the contractor without additional charge therefor." E. Property, Material, etc., to he Furnished by First Party. — The party of the first part should, in general, furnish the real estate and rights-of-way required for the purpose of the work. The first party may desire to furnish other material or supplies which may be on hand or which it may be desirable to furnish through manufactur- ers or other contractors. The latter furnishings are usually described in the specifications. The real estate or rights of way are usually de- scribed in the general conditions. "The party of the first part will furnish all real estate and rights of way reasonably necessary for the work, including land needed for the construc- tion, for borrow pits, for waste dumps, for camp sites and for access to the work. "In case of serious delays in the acquisition of the necessary land for this purpose, an extension of time will be granted the contractor sufficient to compensate therefor. The contractor shall have no compensation for minor delays or interruption caused by the failure to secure such land but shall re- ceive compensation for the actual losses occasioned by serious delays." § 150. Authority of the Engineer. The engineer is commonly designated as the arbiter to decide questions of quantity, quality, workmanship, and any other questions which may arise between the parties to a contract. Commonly, the specifications attempt to make the decisions of the engineer ''final and conclusive" on the contractor, and often on both parties.® The de- cisions of assistants must always be subject to appeal to the Chief En- gineer, and frequently the decisions of the Chief Engineer are made subject to adjustment by a board of arbitration. No agreement on the part of the contractor can make such decision "final and conclu- sive'' if such decisions are unlawful, for a man cannot legally sign 8 Mutuality is the essence of a valid contract and this must exist not only in the contract as a whole but in regard to each obligation df the con- tract. That is, etvery obligation resting on one party must be in considera- tion of a promise or act of the other party. Neither party is bound unless both are bound. If. therefore, the engineer is made the arbitrator of the contract on the part of the contractor his authority is at least doubtful unless the contract also provides that the first party is also by the engineer's decision. 244 General Conditions of the Contract away his own rights to his "day in court." In preparing such clauses or stipulations, the following conditions should be kept clearly in mind : The authority that the engineer can exercise in regard to any con- tract is confined to those functions conferred upon him by the contract stipulations which must be strictly complied with. Under the usual form of contract, the engineer is commonly en- dowed with two duties, — first, as an agent of the owner, and second, as an arbiter of the terms of the contract.^ The engineer's authority does not extend to anything not expressly provided for in the contract, and he cannot vary its terms in any way.^^ If so stipulated, the engineer may determine quantities and classifica- tions, but he cannot act arbitrarily in the premises and must use the methods and classifications prescribed in the contract.^^ If so stipu- lated, he may determine the quality and workmanship of the work done.^^ The right of the engineer or of a board of arbitration to de- termine any question in dispute, cannot be fixed to the exclusion of a review by courts of law or of equity, but such determination may be made a "condition precedent" to such review. ^^ In the supervision and direction of construction work the engineer must exercise certain judicial functions in interpreting the clauses of a contract, but all specifications should be so drawn as to limit this func- tion to the greatest possible extent. When the engineer is made the ar- biter of a contract, he should so far as possible, eliminate prejudice and bias and represent not only his client but the contractor as well, In order to see that the contract is carried out with justice to all con- cerned. It must, however, be practically recognized that the engineer is not an unbiased party. Employed by his client to secure satisfac- tory work which, as a rule, he has designed, and for which he has pre- pared the specifications, his tendencies are to interpret the specifications so as to bring about the results he desires, and any clauses which he has therefore rendered obscure are liable to be interpreted in the favor of his client rather than of the contractor. When a specification is definite, the honest engineer can give but one opinion. The function of the engineer therefore is not that of the legal judge but of the expert judge.

Authority of Engineer 245 A. Supervision and Direction of Work. — The function of the en- gineer is to supervise and direct the work of construction and to see that the same corresponds with the requirements of plans, specifica- tions and contract. The right of direction reserved to the engineer in the contract should not be so extended as to relieve the contractor of the responsibility imposed thereunder, nor should it be such as to permit the engineer unnecessarily to hamper or delay the execution of the work. The common specification that, 'The work must be com- menced and carried on at such points and in such order or precedence as may be directed by the engineer/' is usually unnecessary and un- just. In most cases if desirable, it is quite possible to prescribe the point or points at which the work shall be begun and the order or precedence in which it is necessary that it shall be constructed. The right of the engineer to change this order should be limited to condi- tions where contingencies may arise that clearly make such a change necessary. "Supervision: It is mutually agreed between the parties to this contract that the engineer shall supervise and direct all work included herein. To prevent all disputes and to discourage litigation, it is further agreed by and between the parties to this contract that if it cannot be otherwise agreed, the chief engineer shall in all cases determine the amount of the quantities of the several kinds of work which are to be paid for under this contract, and he shall determine all questions in relation to said work and the con- struction thereof, and he shall in all cases arbitrate every question whicih may arise relative to the execution of this contract on the part of said coni tractor, and his estimate and findings shall be the condition precedent to the right of the party of the second part to any action on the contract and to any rights to receive any money under this contract." "Duration of work: Whenever it is necessary, in order to assure the safe and proper construction of the work, the engineer shall determine the timesi and seasons and the order of precedence under which the work shall bei done. Where the first party is having other work done, either by contract or by its own force, the engineer may direct the manner of constructing the work done under this contract, in order that conflicts may be avoided and the various works being done for the party of the first part may be harmonized." B. Assistants and Inspectors. — In large work a considerable num- ber of assistant engineers, superintendents and inspectors may be re- quired to see that the work is properly performed. In general, their activities should be limited to the special work to which they are as- signed. "The word 'engineer' shall mean the chief engineer of the party of the first part, or his duly authorized agent, assistant engineer, superintendents, 246 General Conditions of the Contract and inspectors acting severally within the scope of the particular duties as^ signed to them." C. Inspection. — Care should be exercised by engineers in charge of large works requiring a number of superintendents and in- spectors fully to advise their subordinates as to the extent and limi- tation of the authority they are to exercise and to furnish instructions as a basis for their work. Instructions should be in writing in order to provide a permanent record and for frequent reference. The in- spector when unfamiliar with his work should request full instructions and should refer all doubtful points to his superior. He should avoid making hasty decisions and should not be too ready to accept sug- gestions of the contractor or of others not in authority. Care in ascer- taining his duties and in determining the methods and manner in which the work should be done at the inception of the work, will prevent errors and embarrassment, increase his knowledge and efficiency and result in his more rapid advancement. The assumption of a knowledge or experience he does not possess and a consequent failure to make necessary inquiries will result in unsatisfactory service and frequently in the loss of position. Inspectors. — In most large public works where numerous inspect- ors are necessary or desirable, men have often to be employed for such positions, who have little or no professional knowledge or practical experience on the work in question. This is apt to be true especially in public work where appointees to such positions are frequently placed by politicians without much regard for ability and sometimes with little regard for integrity. Such inspectors frequently are given or assume an authority which they should not possess and sometimes utilize their position to harrow and annoy the contractor, either through their igno- rance or occasionally for purposes of petty graft. To cover such con- ditions, it has been suggested by Mr. Ernest McCullough^* that a clause be introduced in the general conditions somewhat as follows : "It is mutually agreed that the inspectors on this work shall not be re- garded as deputy engineers, but their duties shall be to report to the en- gineers in charge any deviation from the specifications, and when necessary to order the work stopped until the engineer in charge can give his opinion concerning any disputed question." "All decisions regarding the character of work to be done or material to be furnished or the interpretation of the specifications, shall be referred to the engineer in charge, and the inspectors shall make no changes or devia- tions from the specifications or allowances of any kind, without written au- 1* See Eng. News Supplement, vol. 51, p. 233. Authority of the Engineer 247 thority to that effect from the engineer in charge. It Is furthermore agreed by the parties to this contract that in case the engineer in charge is obliged to be absent from the work for a considerable time and it becomes necessary to delegate his authority during his absence to any one of said inspectors, said inspector shall be appointed in writing and such authority shall cease without notice on the return of the engineer." D. Lines and Grades. "All lines and grades shall be furnished by the engineer but the con- tractor shall provide stakes and such ordinary labor as may reasonably be required by the engineer to assist him in such work. Whenever necessary, work shall be suspended to permit of this work, but such suspension will be as brief as practicable and the contractor shall be allowed no extra compen- sation therefor. The contractor shall give the engineer ample notice of the time and place where lines and grades will be needed. All stakes, marks, etc., shall be carefully preserved by the contractor and in case of their de- struction or removal by him or his employees, such stakes, marks, etc., shall be replaced by the engineer at the contractor's expense." E. Quantities and Measurements. — The subject of measurements is prolific of trouble in specifications unless the methods used are fully understood. It is always desirable to assure such understanding by a specification which shall expressly state the method to be used. This is commonly done by the general statement: "No extra or customary measurements of any kind will be allowed in measuring work under this contract, but the actual length, the solid con- tents, the number and weight only shall be considered, unless otherwise specifically provided." Frequently in various artisans' work, various customary methods of measurements are applied by the trade or by general usage, which in general, are an attempt to equalize the difficult portions of the work and reduce them to the basis of plain work by making extra allowances where such work becomes unusually expensive. Such methods are justifiable in themselves, if fully understood by both parties to the con- tract and indeed simplify, to a considerable extent, the estimate of the parties who are used to making their figures on the basis of such meas- urement. As they are usually readily understood and can be easily applied by the engineer, and more easily applied by the contractor who has been accustomed to them, it would seem desirable that they should be used wherever such use seems feasible. In any event, the matter should be made plain and if such rules are to be used, it should be spe- cifically so stated. If on the other hand such rules are to be ignored, then a clause similar to that previously mentioned should be inserted, so that no 248 General Conditions of the Contract misunderstanding can possibly exist. Even where the method of measurement may seem almost beyond question, differences of under- standing may arise. For example, the measurement of the surface area of a pavement would seem a very simple affair on which the en- gineer and contractor could hardly disagree. Where manholes, catch basins and street railway tracks are located on the street, the expense of fitting around these structures is usually greater than would be the extra cost of pavement which would be constructed were these struc- tures removed ; therefore no allowance is usually made in the amount of paving estimated for the surface occupied by these structures, but if the surface area of the same is deducted, a considerable extra ex- pense should be added to the contract price named for the remainder of the pavement. The same difficulty exists to a greater or less extent in the meas- urements of a great many other structures, such as stone masonry, brick walls, etc. The clauses modifying measurement should there- fore be made explicit, so that they can be literally interpreted. F. To Define Terms and Explain Plans. — Even when much care has been taken in the preparation of plans and in the writing of speci- fications it is commonly found that differences of opinion will arise in regard to their meaning and intent. It is essential, therefore, that the engineer shall be authorized to define the meaning of words and terms, and indicate the limits necessary for their fulfillment under the con- tract. He should also be authorized to explain the meaning and in- tent of the plans and harmonize any apparent discrepancies between the plans and specifications. ''Definition of Terms: Whenever, in the specifications or drawing's ac- companying this agreement, the terms or descriptions of various qualities relative to 'finish,' 'workmanship,' or other qualities of similar kind which cannot from their nature be specifically and clearly described and specified, but are necessarily described in general terms to be 'satisfactory,' 'ftr&t class,' 'workmanlike,' or described by other terms, the fulfillment of which must depend on individual judgment, then, in all such cases, any question of the fulfillment of said specification shall be decided by the chief engineer, and said work shall be done in accordance with his interpretation of the same and to his full satisfaction and approval, and he shall in all Gases be the judge of the fulfillment thereof." "Explanation of Plans: Whenever any misunderstanding shall arise con- cerning the meaning and intent of any of the drawings furnished or to be furnished to the contractor under this agreement, or whenever any appar- ent discrepancies shall arise between said plans and the contract and speci- fications, the chief engineer shall explain the same, and said explanation shall be final and binding on both parties to this contract. Said engineer Authority of the Engineer 249 may amend or correct any errors or omissions in the drawings or specifica- tions when such amendment or correction is necessary to bring out the meaning and intent which is clearly indicated by a reasonable interpretation of the same." G. Emergencies. — On important work, where possible hazards to life and property may arise, or where the welfare of the work may de- pend upon the precautions taken by an individual contractor, such pre- cautions may be neglected, and it is customary and desirable under such conditions to provide that the engineer may do whatever is neces- sary to prevent such possible contingencies. The necessity of exer- cising such a right seldom occurs, but the right to provide such pre- cautions is very essential. ^'Emergencies: Whenever, in the opinion of the engineer, the contractor has not taken sufficient precaution for the safety of the public or the pro- tection of the works to be constructed under this contract, or of adjacent structures or property which may be injured by processes of construction on account of such neglect, and whenever, in the opinion of said engineer, an emergency shall arise and immediate action shall be considered neces- sary in order to protect public or private, personal or property interests, then, and in that event, the said engineer, with or without notice to said con- tractor, may provide suitable protection to said interests by causing such work to be done and material to be furnished and placed as shall furnish such protection as said engineer may consider necessary and adequate. "The cost and expense of such work and material so furnished, shall be borne by said contractor, and if the same shall not be paid on presentation of the bills therefor, then said costs shall be deducted from any amounts due or which may become due said contractor. "The performance of such emergency work under the direction of the engineer shall in no way relieve the contractor from any damages which may occur during or after said precaution has been duly taken by said en- gineer." H. Preliminary Approval. — Where various assistants and inspect- ors are employed in connection with the execution of work, it is desir- able to limit specifically their power of acceptance of work done to the stipulations of the contract. "No engineer, superintendent or inspector shall have any power to waive the obligations of this contract for the furnishing by the contractor of good material and of his performing good work as herein described in full accordance with the plans and specifications. No failure or omission of any engineer, superintendent or inspector to condemn any defective work or material shall release the contractor from the obligation to at once tear out, remove, and properly replace the same at any time upon the dis- covery of said defective work or material." /. Right of Engineer to Modify Methods and Equipment. — The right to modify the contractor's method of work and equipment is a serious reservation which should be included only when the nature of 250 General Conditions of the Contract the work makes it necessary for safety that the work shall be done within a given time or by such means that such safety shall be secured. Such arbitrary requirements can be advantageously made a part of the general conditions only when the standing and experience of the en- gineer are sufficient to make him a reasonable judge of the necessities of the case. "Right to Modify Methods and Equipment: If at any time the methods or equipment used by the contractor are found to be unsafe or inadequate for securing the safety of the workmen or other persons who may be en- dangered thereby, or to secure the quality of work or the rate of progress required under this contract, the engineer may order the contractor to in- crease their safety or to improve their character and efficiency, and the contractor shall comply with such orders. "If at any time the working force of the contractor is inadequate for securing the progress herein specified, the contractor shall, if so ordered, increase his force or equipment, or both, to such an extent as to give rea- sonable assurance of compliance with the schedule of progress. "The failure of the engineer to make such demands shall not relieve the contractor of his obligations to secure the safety of his men, the quality of the work, and the rate of progress required by this contract." /. Right to Retain Imperfect Work. — The contract usually pro- vides that all work which is not in accordance with the plans and specifications shall be taken down and rebuilt in accordance therewith. Under some conditions the removal of work constructed may so greatly impede the progress of the entire work or involve such other losses and damages that it may be desirable or essential to retain the work, even with the imperfection rather than to suffer the consequent loss of its removal and replacement. Whenever such cases may arise it is desirable to include in the general conditions a stipulation that if the imperfections are not of sufficient magnitude to warrant the removal and reconstruction of the work or if such conditions arise as to make such removal and construction impracticable or dangerous the engineer shall have the right to allow the same to remain, but shall be empow- ered to make such reasonable deduction from the contract price of the same as the defect of workmanship, material or construction may fairly warrant. "If any part or portion of the work done or material furnished under this contract shall prove defective and not in accordance with the plans and specifications, and if the imperfection in the same shall not be of sufficient magnitude or importance as to make the work dangerous or undesirable, or if the removal of such work will create conditions which are dangerous or undesirable, the engineer shall harve the right and authority to retain such work, but shall make such deductions in the final payment therefor as may be just and reasonable." Authority of the Engineer 251 K. Arbitration. — One of the serious uncertainties in estimating the cost of work by contractors arises when the decisions of the various questions which may arise under a contract are left to the engineer. Where the contractor has done previous work under a certain engi- neer, his character and the decisions which he will give under the various conditions of contract work may be known, but when a bid is made under an engineer who is unknown or under an engineer who is young and inexperienced, the uncertainties become quite serious and a considerable addition must be made to the prices bid to cover the possibilities of unjust requirements. (See Sec. 126.) In most work it is essential that the work should proceed, and it is desirable as a general rule that the decision of the engineer shall be accepted and complied with so far as the immediate action of the con- tractor is concerned. It is desirable however, both on account of its effect upon the prices bid and on account of fairness that, in all mat- ters of moment where serious differences may arise between the con- tractor and engineer, some provision be made by which an appeal can be taken to a board of arbitration. Where arbitration is provided, the clause in regard to the engineer's decision may be included essen- tially as follows : "Engineer's Decisions: The engineer shall, within a reasonable time, decide all questions or claims of either party to this contract and all mat- ters relating to the execution and progress of the work or the interpreta- tion of the plans, specifications and contract. "Unless otherwise provided, all the engineer's decisions shall be sub- ject to arbitration." The following specification on this subject is written in general accordance with the specification for arbitration recommended by the American Institute of Architects : "Arbitration. — Unless otherwise specifically provided, all questions in dispute under this contract shall be submitted to arbitration at the choice of either party to this contract. The general procedure shall conform to the laws of the state in which the work lies; and wherever permitted by law, the decision of the arbiters may be filed in court to carry it into effect. "If the engineer fails to make a decision within a reasonable time, an appeal to arbitration may be taken, as if his decision had been rendered against the party appealing. In such cases and in a case of an appeal from the engineer's decision, the demand for arbitration shall be filed with him in writing within ten days thereafter; and in no case later than the time of final payment. "The parties may agree upon one arbiter, otherwise there shall be three: one named in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to elect a third within ten 252 General Conditions of the Contract days, lie shall be chosen by the presiding ofl&cial of the nearest Bar Asso- ciation. Should the party demanding arbitration fail to name an arbiter within ten days of the demand, his right to arbitrate shall lapse, and the decision of the engineer shall be final and binding on him. Should the other party fail to choose an arbiter within ten days, the engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are empowered by both parties to take ex parte proceedings. "The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the ar- biters upon any question subject to arbitration under this contract shall be a condition precedent to any right of legal action. "The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal; and if the appeal was taken without reasonable cause, damages for any delay occa- sioned. The arbiters shall fix their own compensation, unless otherwise provided by agreement, and shall assess the cost and charges of the arbitra- tion upon either or both parties. The award of the arbiters must be in writ- ing, and -if in writing shall not be open to objection on account of the form of the proceeding or the award." § 151. Prices and Payments.^ — The stipulation in regard to the financial conditions under which the work is to be done usually relates to the conditions under which estimates have to be given and payments made, together with such other special stipulations concerning guar- antees, bonds and signing of contract as it may be desirable to include. A. Estimates and Payments. "In order to enable the contractor to prosecute the work to advantage, an estimate in writing will be made by the engineer once a month of the amount of work done and material furnished (and material delivered on the ground and to be used in the completed work), and of the value thereof ac- cording to the terms of the contract. The first estimate shall be of the amount or quantity in value of the work done since the party of the second part commenced the performance of this contract, and every subsequent esti- mate, except the final one, shall be of the amount or quantity and value of work done since the last preceding estimate was made. No such estimate of amount or quantity shall be required to be made by strict measurement or with exactness but may be approximate only. "Upon the approval of said estimate by the chief engineer, the party of the first part will pay to the party of the second part eighty per cent, of such estimated value, 'and whenever said contract shall be duly completed, in ac- cordance with the terms herein contained, and in accordance with the spec- ifications, and when said work and material shall be accepted by the chief engineer, for said party of the first part, a careful and detailed estimate shall be made of the value of all work and material furnished under said contract, and the amount due on said work shall be paid to said party of the second part, provided however it is not considered necessary by said first Prices and Payments 253 party to retain a certain proportion of same as elsewhere provided for pro- tection against claims for labor and material, for damages, for royalties or otherwise, and excepting also any amount retained as a guarantee for the maintenance of the work or material furnished under this contract, or for . forfeiture." B. Delayed Payments. "In case any payment to the contractor on any estimate is delayed by the party of the first part beyond the time provided herein, said first party shall pay the contractor interest on the amount due at the rate of six per cent, per annum for the period of such delay. The term for which said interest shall be paid shall, in the case of progress estimates, date from the 10th day after the date of said estimate, to the date of payment of the esti- mate, and in the case of the final estimate from thirty days' after the filing of the certificate of completion and acceptance to the date of final payment of the final estimate. "If interest shall become due on any progress estimate, the amount thereof shall be added to the succeeding estimate; and if interest shall be- come due on the final estimate, it shall be added to such final estimate and paid therewith or by a special voucher within fourteen days thereafter. The contractor shall not be entitled to interest on any sum or sums which by the terms of this contract the party of the first part may be authorized to retain. It is hereby agreed that such interest payments, if any, are to be in lieu of any claims of the contractor for alleged damages, for breach of contract, or otherwise, on account of delayed payments." C. Extra Work. "All extra work done under this contract shall be paid for at actual cost plus fifteen per cent." (Improper specification.) The above Is quite a common form of specification for extra work, but is objectionable on account of its failure to define what is meant by "actual cost." The actual cost of a piece of work will of necessity include the cost of all material, labor and supplies furnished for the work in question. It includes also the cost of the time that any fore- man may give to this special work. The work in general must be re- garded as including not only the above items, but also the cost of gen- eral superintendence, office expenses in immediate connection with the work, timekeepers and other salaries and the cost, or at least the de- preciation, on the tools and machinery used in connection with the same, also other general expenses. If the contractor is doing several pieces of work, each job must bear its portion of general expense of his main office, with traveling expenses to and from the work and even of other lettings. Unless these are included, plus a profit, the con- tractor would not be able to remain in business, for all the expenses named must be paid from the amount received for the work in question. 254 General Conditions of the Contract It is sometimes argued that extra work and its percentage of profit should be based not only on the items mentioned under actual cost, but also on the cost of general supervision or overhead charge and gen- eral expense or charge outside of the job. When a contract job is taken, the items of general expense, over- head, etc., are necessarily calculated and apportioned among the vari- ous jobs of the contractor, and unless the total quantity of work to be done on some or all of these contracts has been materially reduced, an amount has been previously included sufficient to take care of these items. Hence, justice does not require that such items should be in- cluded in part of the cost of extra work unless the item of extra work is considerable and adds to such general expense. It may also be noted in this connection that, if overhead charges of a contractor's general office were to be considered as a part of the actual cost of the work under each individual contract, this might become bur- densome in the event of the contractor's having, during a given time, only a single job to which all of such expenses would have to be charged. It therefore seems just to eliminate the general ex- pense and overhead charge both of the contractor's general work and of the particular job in question, but to include all items which go to make up the actual cost of this work, whether ordinary or extraor- dinary, when incurred directly on account thereof. In general, this should include labor, material, supplies, immediate supervision, con- tractor's liability insurance, use and depreciation of small tools such as picks and shovels, and any other expenses directly incurred by or in consequence of the special work performed. Unless all of these are included, the ten or fifteen per cent, allowed to cover profit and general expense will be too small for the purpose, as insurance on cer- tain classes of hazardous work may amount to several per cent, on the pay roll ; and the cost of foreman, especially on difficult work, may sometimes be almost or quite as great as so-called profit allowed. General expense also may frequently vary from as low as five per cent, to as high as ten per cent, of the contract price. It will be noted therefore that in order to be fair, all actual expenses directly connected with the work should be included, and a liberal percentage above this allowed for general expenses and profit. In order that all extra w^ork may be properly checked, it is desir- able that the engineer should keep an account of the work performed and the material furnished for the same each day. If the work is simple a brief note or memorandum only will be necessary, but if at all Prices and Payments 255 complicated it is desirable that the contractor be required to furnish a daily memorandum and a monthly bill of his charges on such amount. "Extra Work: If during the performance of this contract the engineer shall order in writing other work done or materials furnished which in his opinion cannot be classified under the unit prices of this contract, the con- tractor shall do and perform such work and furnish such material and shall be paid therefor the actual cost thereof plus fifteen per cent, in addition thereto. The actual cost is hereby defined to include the cost of all labor and materials necessary for the performance of the extra work, including any extra expenses increased directly on account thereof, also the wages of foremen and the expenses attached to contractor's liability insurance cov- ering the labor so employed, "No allowance shall be made for overhead charges, general superin- tendence, general expenses, contingencies, or use and depreciation of the construction plant; neither shall said charges include the maintenance of the contractor's camp or office, unless such camp or office be maintained primarily on account of such extra work. The contractor shall submit to the engineer a monthly bill of all charges on account of such extra work, and if the engineer so desires shall also furnish a daily memorandum of all such charges. '' When the extra work is of considerable magnitude the cost should include — "also the pro rata wages of the Superintendent, General Foreman, Time Keep- ers and Material or Commissary Clerks." If an expensive construction plant is to be used on such work pro- visions should be made to pay a certain sum for its use and deprecia- tion, fixed either by an advanced agreement, a supplementary con- tract, or by arbitration. While 15 per cent, added for general expense and profit may be a fair compensation for extra work with small tools and when the plant investment is small it would be totally inadequate when machinery valued, perhaps, at from $10,000 to $25,000 is to be used. The use of such machinery should be covered by an allowance commensurate with the daily rental charge which would be made for such machinery on regular work. Where such use is to be anticipated a rental price may be fixed for such machinery in the itemized pro- posal. D. Price for Work. — The prices bid by the contractor for the con- struction of work can be made a part of the contract by reference to the proposal which should be attached to the agreement or by re-writ- ing the prices named in the bid directly in the agreement. "In consideration of the furnishing of the material and the completion of all work by the said party of the second part, and on the completion of all work and of the delivery of all material embraced in this contract in 256 General Conditions of the Contract full conformity with the specifications and stipulations herein contained, the party of the first part agrees to pay the said party of the second paxt the prices set forth in the proposal hereto attached, marked 'Exhibit C,' which is hereby made a part of this contract. And the said party of the second part hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to the specifications and requirements of the engineer. "On the condition of the true and faithful performance of all the pro- visions in this agreement and in the specifications, the party of the first part agrees to pay to the said party of the second part the following suxos, to wit: , in full payment for all work, material and supplies indicated in this contract embracing the complete and satisfactory con- struction of said work as defined and described in said specifications in all parts and requirements.' E. Bond, Sureties and Special Guarantees. (a) ''Bond: It is further agreed by the parties to this contract that this contract shall be executed in triplicate, one copy being retained by the party of the first part, one to be delivered to the contractor, and one to the chief engineer. The party of the second part agrees to execute a bond for the sum of dollars for the satisfactory performance of the work in the form provided for that purpose, and it is agreed that this contract shall be void until such bond is furnished and approved by (b) ''Sureties: With the execution and delivery of this contract the con- tractor shall give security for the faithful performance of the contract by filing with the board one or more surety bonds in the form annexed hereto, the aggregate amount of which shall be not less than forty per cent, of the estimated total contract price. Each bond must be signed by the con- tractor and the sureties. The sureties, and the amount in which each will, qualify, must be satisfactory to the board. "Should any surety upon the contract be deemed unsatisfactory at any time by the board, notice wall be given the contractor to that effect, and the contractor shall forthwith substitute a new surety or sureties satisfactory to the board. And no further payment shall be deemed due or shall be made under this contract until the new surety or sureties shall qualify and be accepted by the board. "At the expiration of each year after the date of contract the liability of the sureties under the bonds may be reduced to that extent to which, in the opinion of the board, the need for surety is reduced, until such lia- bility shall amount to twentj-five per cent of the original liability, at which amount the bonds shall remain in full force and virtue until the completion of the entire work." F. Guarantees, Bonds, or Per Cent. Retained. — Guarantees made for maintaining the work or operating the plant for a definite period are generally protected either by a bond or by the retention of a per- centage of the contract price. Form of Bond 257 "The said contractor further agrees that the said city shall be and is hereby authorized to retain out of the money payable to the contractoor under this agreement, the sum of five per cent, of the amount of this con- tract and to expend the same in 'the manner hereinafter provided for in making such repairs on the line of said work as the engineer may deem, necessary. The said contractor further agrees that if, at any time during a period of six months from the date of the final completion of the work contemplated in this contract, any part of said work shall, in the opinion of the said engineer require repairing, and said engineer shall notify the contractor in person or by mail to make the repairs so required, and that if the said contractor shall neglect to make such repairs, to the satisfaction of the said engineer, within three days after giving or mailing such notice to the said contractor, his agent or attorney, then the said engineer shall have the right to employ such other person or persons as may be deemed proper to make the change; and the said party of the first part shall pay the expense thereof, out of the sum retained for the purpose, by it, as before mentioned. And the said city further agrees upon the expiration of the said period of six months, provided that the said work shall at that time be in good order, that the said contractor shall be entitled to receive the whole or such part of the sum las't aforesaid as may remain after the ex- pense of making said repairs in the manner aforesaid shall have been paid Lherefrom." § 152. Form of Bond. — The following form of bond has been adopted by the Board of Directors of the Miami Conservancy District in connection with the extensive flood protection work which is soon to be undertaken along: the Miami River.* 't> BOND Knozv all men by these presents, that we , , , of , County of and State of , as Principal, here- inafter called the Contractor, and , , organized under the laws of the State of and duly authorized to transact busi- ness within the State of Ohio, as Surety, hereinafter called the Surety, are held and firmly bound unto THE MIAMI CONSERVANC^/ DISTRICT, a corporation organized under the laws of the State of Ohio, with its principal place of business located at Dayton, Cotinty of Montgomery, and State of Ohio, as Obligee, hereinafter called the Dis- trict, in the sum of dollars ($. . ) lawful money of the United States, for the payment whereof to the District the Contractor binds , heirs, executors, administrators, sticcessors, and as- signs, and the Surety binds itself, its successors, and assig^ns, firmly by these presents. See Report of A. E. Morgan, Chief Engineer, Vol III d 17. 258 General Conditions of the Contract Whereas, the Contractor and the District have entered into a writ- ten contract, dated the day of 191 . -, hereinafter called the Contract, a copy of which is attached hereto and made a part hereof, for The condition of this obligation is such that if the said Contractor shall pay all persons, firms or corporations who perform labor or fur- nish equipment, supplies and materials for use in the work thereunder, and shall satisfy all claims against the district, for damages to life, limb or property that may be caused by the acts of, or negligence of, the Contractor or any of his agents or employees, and shall satisfy all suits or claims brought against the District arising from the violation of any law, ordinance, regulation, order or decree on the part of the Con- tractor or any of his agents or employees ; or from any infringement, or alleged infringement of patents in the work under said Contract ; or howsoever originating from any of the operations under said Contract ; and shall fully indemnify and save harmless the District from all cost and damage which it may suffer by reason of failure so to do, and shall fully reimburse and repay the district all outlay and expense which the District may incur in making good any such default, and in all other particulars shall faithfully perform the contract on his part according to all the terms, covenants, and conditions thereof and within the time specified therein, then this obligation shall be void ; otherwise to remain in full force and effect.

Responsibility of Contractor as Affecting Party of the First Part. — Contracts for work or for furnishing material, etc., are usuilly entered into on account of the familiarity and equipment of the contractor which will enable him to do the work of this class to ad- vantage, and in order that the party of the first part may have the work done without personal responsibility either as to the operations of construction or the ultimate results of the work. In order that the contractor may be required to assume these responsibilities, various stipulations are necessary, and such responsibilities must be stipulated in detail, and great care must be exercised on the part of the engineer to see that all such matters be fully covered. A. Persons Interested in Contract. 260 General Conditions of the Contract "No person or persons other than whose name affixed hereto as part., of the second part now ha., any interest hereunder as contractor... This contract shall be void if any member of the board or other officer of the city of or any person in the employ of said board or said city is or shall become directly or indirectly interested as con- tracting party, partner, stockholder, surety or otherwise in the perform- ance of this contract or in the supplies, work or business to which it re- lates or in any portion of profits thereof. Provided that incidental interest such as the ownership of stock or bonds in a railroad, telephone or other public utility, which may as an incident to its usual business furnish serv- ices or supplies to the contractor, shall not be included in the meaning of this provision." B. Personal Attention of Contractor. "The contractor shall give personal attention to the faithful prosecution and completion of this work and shall be present either in person or by duly authorized representative on the site of the work continually during its progress. He shall maintain an office on or adjacent to the site of the work." C. Contractor's Address. "Both the address given in the proposal upon which this contract is based and the contractor's office at or near the site of the work are hereby designated as places to either of which notices, letters or other communica- tions to the contractor may be mailed or delivered. The delivering at either of the above named places of any such notice, letter, or other communica- tion from the party of the first part to the contractor shall be deemed suffi- cient services thereof upon the contract, and date of said services shall be the date of such delivery." D. Contractor's Agent. — To avoid the assumption of personal re- sponsibility by the party of the first part, the right to direct individual workmen should not be reserved. Such instructions as may be neces- sary must be given only to the contractor or to his duly authorized agent, and to assure the constant attendance of some duly authorized agent of the contractor, during the progress of the work, requires a specific clause in the agreement. "The contractor, during his absence from the work, shall keep a com- petent superintendent or foreman upon the work, fully authorized to act for him in his absence, and to receive such orders as may be given for the proper continuance of the work. Notice of any imperfections in the work or material furnished to any foreman or agent in charge of any portion of the same, in the absence of the contractor, shall be considered as notice to the contractor." E. Observance of Laws and Ordinances. — When an agreement is made, especially by a municipal corporation, for work to be done in city streets, or when the public may become interested or affected, a Responsibility of Contractor 261 stipulation should be included binding the contractor to observe the laws and ordinances so that he may claim no exemption on account of the provision of the agreement. "The party of the second part shall be subject to .all laws and ordi- nances of the city of , within which city this agreement is to be fulfilled, and said contractor shall be entitled to no exemption there- from on account of this contract." F. Protection Against Negligence and Damages. — In every agree- ment stipulation should be included providing for the protection of public property, and the liability of the contractor should be fixed for any negligence of himself or of his employees and for resulting dam- age occasioned thereby. "Should any work be done or material furnished or placed on the pub- lic streets or ways or in any other place where protection is necessary, the contractor shall, at all times, and especially during the night, put up and maintain such barriers and red lights and take such other needful precau- tions as may be necessary to effectually prevent the happening of any acci- dents in consequence of the work being done or material being deposited in such places, and the contractor shall be liable for all damages occasioned in this way or by reason of his act or neglect or of that of any authorized sub-contractor or any agent, employee or workmen; and the said contractor shall save and keep harmless the said first party from all suits or demands for damages alleged to have occurred to persons or property by reason of said work or of so placing said material or from said act or negligence. "And the said party of the second part further agrees during the per- formance of the work to take all necessary precaution and to place proper guards for the prevention of accidents and put up at night suitable and sufficient light and will indemnify and save harmless the said parties of the first part from all damages and costs to which they may be put by reason of injury to the person or property of another, resulting from negligence or carelessness in the performance of the work or in guarding the same, or from any improper material used in its construction, or by or on account of act or omission of the said party of the second part or the agent thereof; and the said party of the second part hereby further agrees that the whole or so much of the money due under or by virtue of this agreement as shall or may be considered necessary by the aqueduct commissioners shall, or may be, re- tained by the parties of the first part until all suits or claims for damages, as aforesaid, have been settled and satisfactory evidence to that effect fur- nished the said commissioners. "The said contractor shall take proper means to protect the adjacent or adjoining property or properties in any way encountered or which might be injured by any process of construction, to be undertaken under this agreement, and he shall be liable for any or all claims for damages on ac- count of his failure to fully protect all property injured during or c.'\ a'^- count of such construction." 262 General Conditions of the Contract G. Protection Against Claims for Labor and Material. — The agree- ment should contain stipulations protecting the party of the first part from ail claims for labor and material furnished for the completion of the contract, and it should also contain any special restriction neces- sary for the method of paying labor on the work. "The said party of the second part agrees that he will indemnify and save harmless the party of the first part from all claims against said first party for material furnished or work done under this contract, and it is further agreed by the party of the second part that said second party shall if so desired furnish the said first party satisfactory evidence that all per- sons who have done work or furnished material under this agreement have been duly paid for such work or material, and in case such evidence is de- manded and not furnished to the aforesaid first party, such amount as may, in the opinion of the said first party, be necessary to meet the claims of the persons aforesaid, may be retained from the money due said party of the second part under this agreement, until satisfactory evidence be furnished that all liabilities have been fully discharged." H. Protection Against Royalties on Patented Inventions. — The party letting the work should commonly be protected from suit for damages occasioned by the use of patented articles on or in connection with the work or the installation included in the contract. A stipula- tion should therefore be included in the specifications by which the contractor agrees to protect the party of the first part from any and all royalties on any patented invention installed or used by him in con- nection with the work, or if the said party of the first part is to pay for such royalties it should be so provided and specified. Such stipu- lations should especially be provided in the agreement covering in- stallation of machinery or in the installation of various works for man- ufacturing or similar installation. The contractor should not, how- ever, be held for the use of patented articles or methods which are specified in the contract, but arrangements for the use of such patents should be made by the engineer or other agent of the party of the first part. "The contractor shall protect and save harmless the party of the first part from all and every demand for damages, royalties or fees on any patented invention used by him or used in connection with the work done or material furnished under this contract, and it shall be the duty of such contractor if so demanded by the party of the first part to furnish said first party with a proper legal release or indemnity from and against all such claims, and any or all payments may be withheld from said contractor until said release is furnished if the party of the first part so elects. The above shall not, however, include any patented invention or process ordered by the engineer or specified in the contract." /. Assignment and Subletting. — In cases where the agreement is drawn for the personal skill or professional knowledge of the con- Responsibility of Contractor 263 tractor, no assignment or subletting of the work would naturally be permitted. In other cases, it is usually desirable that the assignment or subletting of the work, or any part thereof, shall be done only with the knowledge and consent of the parties of the first part or their duly authorized agents. It is therefore customary to include in the agree- ment some clause, stipulating such restrictions in regard to this matter as the conditions may make desirable. "The said contractor further agrees that he will give his personal at- tention to the fulfillment of this agreement and that he will not sublet the aforesaid work or the furnishing of the aforesaid material, but will keep the same under his personal control, and that he will not assign by power of attorney or otherwise any portion of said contract unless by and with the previous consent of the first party as signified by endorsement of this agree- ment by the officials whose signatures are attached hereto." /. Abandonment and Forfeiture. — In order to provide for due progress on the work under the conditions of abandonment of the same by the contractor, it is customary to introduce a stipulation whereby the parties of the first part may, after due notification to the con- tractor's sureties, carry the work to completion. "In case the contractor shall abandon the work and fail or refuse to commence it again within days after notification from the first party, or if he should fail to comply with the orders of the engineer or with this agreement or with the specifications hereto attached, then, and in that case, the sureties on the bond shall be notified and directed to complete the same. In case the sureties fail to comply with the notice, the first party may, within days after serving such notice, carry on the work at the expense of the contractor and sureties." In the flood protection work of the Miami Conservancy District where large and important contracts are involved and where the matter of delays may become serious, a more elaborate provision for termi- nating the contract has been prepared after serious and thorough con- sideration.* "If the work to be done under this Contract shall be abandoned by the Contractor, or if this Contract shall be assigned, or placed in bankruptcy, or the work sublet by him, otherwise than as herein specified, or if at any time the Engineer shall be of the opinion, and shall so certify in writing to the Board, that the performance of the Contract is unnecessarily or unreasonably delayed, or that the Contractor is violating any of the conditions or agree- ments of this Contract, or is executing the same in bad faith or not in accord- ance with the terms thereof, or is not making such progress in the execution of the work as to indicate its completion within the time specified in this Con- tract, or within the time to which the completion of the Contract may have Report of A. E. Morgan, Chief Engineer, Vol. Ill, p. 44. 264 General Conditions of the Contract been extended by the Board, the Board may notify the Contractor to discon- tinue all work or any part thereof, under this Contract, by a written notice to be served upon the Contractor as hereinbefore provided, and a copy of which notice shall be given to his Surety, or the authorized agent for the latter; thereupon the Contractor shall discontinue the work, or such part thereof as the Board shall designate, and thereupon, the Surety may, at its option, as- sume this Contract, or that portion thereof on which the Board has ordered the Contractor to discontinue work, and proceed to perform the same, and may, with the written consent of the Board, sublet the work or portion of the work so taken over; provided, however, that the Surety shall exercise its op- tion, if at all, within two weeks after written notice to discontinue work has been served upon the Contractor and upon the Surety or its authorized agent. The Surety, in such event, shall take the Contractor's place in all respects, and shall be paid by the party of the first part for all work performed by it in accordance with the terms of this contract; and if the Surety under the provisions hereof shall assume said entire Contract, all moneys remaining due the Contractor at the time of his default, shall thereupon become due and payable to the Surety as the work progresses, subject to all of the terms of this Contract. "In case the Surety does not, within the hereinbefore specified time, exer- cise its right and option to assume this Contract or that portion thereof on which the Board has ordered the Contractor to discontinue work, then the Board shall have the power to complete by contract or otherwise, as it may determine, the work herein described, or such part thereof as it may deem necessary, and the Contractor agrees that the Board shall have the right to take possession of and use any of the materials, plant, tools, equipment, sup- plies and property of every kind provided by the Contractor for the purpose of his work, and to procure other tools, equipment and materials for the completion of the same, and to charge to the Contractor the expense of said contracts, labor, materials, tools and equipment and expenses incident thereto. The expense so charged shall be deducted by the District out of such moneys as may be due or may at any time thereafter become due the Contractor under and by virtue of this Contract, or any part thereof. The Board shall not be required to obtain the lowest figures for the work of completing the Contract, but the expense to be deducted shall be the actual cost of such work. In case such expense is less than the sum which would have been payable under this Contract if the same had been completed by the Contractor, then the Contractor shall be entitled to receive the difference; and in case such ex- pense shall exceed the amount which would have been payable under the con- tract if the same had been completed by the Contractor, then the Contractor shall pay the amount of such excess to the District on notice from the Board of the excess so due; but such excess shall not exceed the amount due, under this Contract, at the time the Contractor is notified to discontinue said work, or any part thereof, plus the amount of the bond or bonds executed by the Contractor for the performance of this Contract. When any particular part of the work is being carried on by the Board, by contract or otherwise, under the provisions of this section, the Contractor shall continue the remainder of the work in conformity with the terms of this Contract, and in such man- ner as in nowise to hinder or interfere with the persons or workmen em- ployed, as above provided, by the Board." Responsibility of Contractor 265 K. Time and Order of Completion — Liquidated Damages — Right to Discontinue Work. — The Time of completion of a contract is often of great importance, and in all contracts, even where the importance of early completion is not great, a time of completion should be specified, otherwise the work may be delayed unduly. The time of completion must often be made the essence of a con- tract on account of : (a) The necessity of having a given work completed to meet cer- tain emergencies, contingencies or uses. {h) On account of the losses of interest on investment or other damages which may be occasioned by delay. For these reasons, and perhaps for many others which might be mentioned, a specific time of completion should be stipulated in the agreement. It is also frequently desirable that certain portions of the work shall be completed first, and that other portions of the work shall follow in a given order, to best serve the purposes of the construction. In such cases, the order of completion may be an essential feature of an agreement. The character of the work may also be such that it cannot be properly performed under certain weather conditions, and it may become desirable to discontinue the work when such conditions arise. When such conditions are likely to arise, stipulations to this ef- fect should be included in the agreement. There can be no doubt that a contractor is legally bound', by a stipulation to complete a contract on a given day or date provided the time limit is reasonably possible, and provided also that he is not de- layed by conditions entirely beyond his control. When a contractor delays the time of completion beyond that specified in the contract, and especially when such delays are caused by his own negligence, he is undoubtedly liable for damages occasioned by such delays, and such damages can be collected by due process of law. "The party of the second part further agrees that the work shall be commenced and carried on at the point and in the order of precedence speci- fied. "The said party of the second part further agrees that he will commence the work within days after the execution of this contract, and will progress therewith so that by the day of , 19. ., the work shall be completed in accordance with this agreement." L. Rate of Progress and Forfeiture. — When the time of comple- tion is important, and the length of time necessary for construction is considerable, it is not sufficient simply to provide that the work shall 266 General Conditions of the Contract be completed at a certain date, for with such a provision no recourse can be had against the contractor until after the date of completion. To assure the prompt completion of the work, it is desirable in all such agreements to stipulate that the rate of progress shall be made an es- sential feature of the contract, and it should be provided that unless the rate of progress necessary to complete the work in the specified time is maintained, the contract may be forfeited and relet, or the work prosecuted by other means, which means should be specified in detail. Failure to maintain a given rate of progress and the consequent forfeiture of a contract are serious features when forfeiture is actually declared, and are apt to lead to litigation. For this reason, the method "of determining progress should be clearly defined, so that the right to declare forfeiture in case forfeiture is declared, may be perfectely clear. The fundamental basis on which the rate of progress and comple- tion of all contracts must depend, is the number of days' work to be done, and the time available for doing it. Under ordinary conditions, the rule for determining the rate of progress is first to determine the total number of days w^orked included in all classes of work covered by the contract, and divide by the time. The quotient will be the num- ber of days' work which must be done in each unit or division of time. The factors in the problem are the quantity of work, and the time in which it is to be done ; and the ordinary and usual method of calculat- ing the quantity of work is by the day's work. The term "day's work" represents the amount of work which can be done by one man in one day, and is independent of the pay which the man receives: thus, a laborer at $1.75 per day, a stone-cutter at $6.00 per day, or a sculptor at $50.00 per day would each do one day's work in one day's time. The cost, therefore, is not the measure of quantity of work, although it is the measure of value. In all contracts, however, where one class of work only is involved, or where the classes are so similar that the cost of the same is in pro- portion to the work done, quantity and values are essentially similar, and the rate of progress may be measured by either quantity or value. From the inception of the work, the engineer must bear in mind the time required for its completion, and the rate of progress must be based upon the actual time which will be required for completion. Often on account of the nature of certain portions of the work, a greater portion of time must be allowed for the execution of certain classes of work, and on others on account of limited space or other conditions where only a certain number of days' work per day are possible. Frequently Responsibility of Contractor 267 correlative work, or work which depends for its execution on the com- pletion or progress of other work, will take no especial or distinct por- tion of time for its execution, as it can progress as other work pro- gresses. In the practical execution of work, another feature must be con- sidered in this connection, that is, the preparation for the execution of work. It takes a certain length of time to get the plant on the ground, and to get it in shape for the proper performance of its functions. Then, too, in the beginning of a work it is impossible to accomplish as much the first month as the second, or the second month as the fourth, but a considerable time must elapse before the work is in full swing and can be systematically prosecuted. This is due to the fact that men and machinery are new and also to the fact that work cannot be rapidly prosecuted until it is opened up and rendered accessible. Rate of progress also depends on the plant installed, and the spec- ifications requiring a higher rate of progress may involve an expendi- ture for a plant which will add materially to the cost of the work. The plant must necessarily be selected in view of the time of completion and the rate of progress required ; thus, a single steam shovel will handle from 600 to 1,000 yards of earth per day and cannot be set up to advantage for removing less than 100,000 yards. If the rate of progress specified is so great that a large number of shovels are re- quired, the investment involved is very large, and the cost per yard may be* greatly increased over what the cost would be if sufficient time were allowed so that only one shovel would be required. • A high rate of progress of work is often possible where it is not feasible, for the element of cost is important not only to the contractor who takes the work, but also to the party having the work done, for the contractor must base his charges on the absolute requirements of construction. The specifications of the Sanitary District of Chicago follow : "The work done each month shall not be less than the proportion in- dicated by the total number of months, provided that the first four months after notice to begin shall be considered as one month and the last two months before completion as one month, and provided further that this rate shall not be required if at any time the aggregate work done exceeds the total proportion due to the time that has passed since notice to begin work, and always provided that the sanitary district shall not be obliged to make payment in excess of the above month in proportion." The Aqueduct Commission of the City of New York, in a con- tract for Section 13 of the New Croton Aqueduct required : 268 General Conditions of the Contract "That the rate of progress shall be such that, 1st, in 100 days from the execution of the contract both the shafts shall be excavated to their full depth; 2d, in each and every month, commencing GO days from the time the shafts must be excavated, not less than one-ninth of the total length of each heading shall be excavated; 3d, on or before the 30th day of September, 1887, the whole work shall be completed in accordance with this agreement." In a contract for the improved sewerage of the City of Lynn, Massachusetts, the requirements for time of beginning, rate of prog- ress, and time of completion, are as follows : "The said contractor further agrees that he will commence the work within ten days of the execution of the contract and will progress there- with so that by the 20th day of October, 1887, the value of the work done, and the materials delivered shall at least equal one-third of the value of the total amount of work to be done and the materials to be delivered under this contract and by the 15th of November, 1887, said value shall at least equal one-half of said total amount, and by the first of July, 1888, the whole work shall be completed in accordance with this agreement." This last specification includes work in which the amount of work and material is fairly measured by the value of said work and material. In many contracts this is frequently not the case. For example, in works for construction of levees, which require the clearing and grub- bing of land and in which the price for said clearing and grubbing is included in the price per cubic yard for the levees, the cost of the pre- liminary work may be very considerable and may require a considerable amount of labor and time, for which, in the contract, no direct return is received, and an allowance for time must necessarily be made for the execution of these preliminary w^orks. It has been suggested by Mr. E. R. Shnable that a satisfactory method of handling the rate of progress would be to provide a blank in the proposal, and require the contractor to fix his own rate of prog- ress in percentages, essentially as follows : "If awarded the contract for this work propose to complete the same at the rates indicated in the following table in which the progress is ex- pressed in percentages of the money value of the work to be performed under the contract, at the various dates specified. On October 1, 1916 per cent. On November 1, 1916 per cent. On December 1, 1916 per cent. On January 1, 1917 per cent. On February 1, 1917 per cent. On March 1, 1917 per cent. On April 1, 1917 per cent. On May 1, 1917 100 per cent. May I being the date of completion fixed by the specifications or otherwise. Responsibility of Contractor 269 M. Liquidated Damages. — Liquidated damages to the extent of the actual damages occasioned by the delay wi 1 undoubtediy consti- tute a legal and valid claim. The agreement may fix a certain sum as damages for delay, but there is always a question as to whether the amount fixed may be actually retained or recovered at law. While it is a common practice in such stipulations to define the sum to be re- tained as "liquidated damages," it is nevertheless true that the court will usually not regard such sum as actual ''liquidated damages," unless it can be shown that the actual damages sustained were equal to or greater than the amount as named. In such cases the court will not sustain a penalty but will sustain the collection or retention of the ac- tual damage when said damage is not less than the amounts named in the contract.^^ It may here be noted that difficulties in the way of construction, casualties, accidents, etc., are not excuses which will tend to relieve the contractor from "liquidated damages." On the other hand, a delay occasioned by the party of the first part or by other contractors may relieve a contractor from "liquidated damages."^^ When liquidated damages are actually incurred, such damages are sometimes waived by a failure to notice the default or by allowing the work to continue and payments to be made as if such default had not occurred." Where the time of completion is a matter of real moment and "liquidated damages" are specified for delays, it is desirable in the in- terest of fairness and justice to insert also a bonus clause for the com- pletion of the work in advance of the time requirement. The bonus clause also adds the element of mutuality and assures the enforcement of either penalty or bonus as a matter of mutual agreement. "Should the contractor fail to complete the work as herein specified within the time named, unless granted an extension of time by the party of the first part, he shall be liable for the wages of the superintendent on his work from the above specified time to the date of the engineer's certificate of completion of his work, and the amount of such wages shall be deducted from the money which may be due to him from the amount of the final esti- which may be due or become due to the said contractor, under this agree- ment, the sum of dollars ($..) per day as liquidated damages for every day the aforesaid work may be uncompleted over and beyond the time herein stipulated for its completion: provided, however, that the said first party shall have the right to extend the time for the completion of the said work if he should decide so to do. "And the said party of the second part agrees to commence the work herein required to be done within days after the signing of this con- tract, and that the rate of progress shall be such that on or before the .... day of , 19.., the whole works shall be completed according to this agreement. 270 General Conditions of the Contract "In case the said party shall fail to fully and entirely, and in con- formity with the provisions and conditions of this agreement, perform and complete the said work and each and every part and appurtenances thereof within the time hereinbefore specified for such performance and comple- tion, or within the said further time which may be allowed by for such performance and completion, the said party of the second part shall and will pay to the said party of the first part the sum of ( $ • • ) for each and every day that the said party of the second part shall be in default, which said sum of ($••) per day is hereby agreed upon and deter- mined by the parties hereto as the damages which the party of the first part will suffer by reason of such default and not by way of penalty, and the said parties of the first part may deduct and retain the said sum of ($••) per day out of any money which may be due or become due under this agreement." "The time of completion is of great importance, and it is mutually agreed between the parties to this contract, that in case said party of the second part shall fail to fully and entirely perform and complete the said work and every part thereof, in full conformity with the provisions and conditions of this agreement, and within the time herein before specified for such perform- ance and completion, then, and in that event, the said party of the second part shall and will pay to the said party of the first part the sum of ( $ . . ) for each and every day that said work shall remain uncom- pleted. In event, however, that said work shall be fully completed before the date specified for such completion, then and in that event, the said party of the first part shall and will pay to the said party of the second part, the sum of ($. . ) for each and every day that the said party of the second part shall have completed the contract in advance of the time of completion specified. The said party of the first part may deduct and retain the said sum of ($• . ) per day for each day of delay beyond the date of com- pletion specified, out of any moneys which may be due or become due under this agreement, or shall add to the final payment of the party of the second part, the sum of ($..) for each day the work is completed prior to the specified date of completion." § 154. Conduct of the Work. A. Keeping of Plans and Specifications Accessible. — It is usually desirable to have plans and specifications readily accessible on the work, in order that the requirements of the contract can be discussed and defined by the engineer or inspector with the contractor and his su- perintendent. These papers can usually be made most conveniently accessible by being kept at the contractor's local office or in some other manner on the work. A clause to this effect is commonly desirable. "The contractor shall keep a copy of the plans, profiles and specifications constantly accessible on the work for the use of the engineer and inspector in the work of supervision. The party of the first part shall, however, furnish free of charge, such plans, profiles and specifications as are necessary for this purpose." Conduct of the Work 271 B. CJiaractcr of Workmen. — (Foreign labor, convict labor and eight-hour law.) While the party of the first part, if he would place the responsibility as to accidents and ultimate results on the contractor, must not undertake the direction of individual workmen, he may pro- vide that such workmen shall be faithful, orderly, competent and skill- ful. Where work is to be done for the public, or must be done under any statutory enactments, it is desirable a^so to include a stipulation reciting the restrictions of such statutes. "The said party of the second part agrees to employ only orderly, com- petent and skillful men to do the work; and that whenever the engineer shall inform him in writing that any man or men on the work are, in his opinion, incompetent, unfaithful or disorderly, such man or men shall be discharged from the work and shall not again be employed on the same without the engineer's written consent." The following extract from one of the specifications of the United States' Reclamation Service is an example of the restrictions which it may be necessary to introduce in certain contracts : "In all construction work eight hours shall constitute a day's work and no Mongolian labor shall be employed thereon. The importation of foreign- ers and laborers under contract to perform labor in the United States or the Territories or the District of Columbia is prohibited. (Sec. 3738, Rev. Stat. U. S. Acts: Aug. 1, 1892, 28 Stat. L, 340; June 17, 1902, Sec. 4, 32 Stat. L, 388; Feb. 26, 1885, 23 Stat. L., 332; and Feb. 23, 1887, 24 Stat. L., 414.) In the performance of this contract no persons shall be employed who are un- dergoing sentences of imprisonment at hard labor imposed by courts of the several States, Territories or municipalities having criminal jurisdiction. (Executive order, May 18, 1905.)" C. Losses and Damages. — It is also desirable that a clear under- standing shall exist as to who is to bear the expense due to casualties or to losses due to the action of the elements or expenses incurred from other unforseen conditions or contingencies which may increase the cost of the work. These conditions are usually controlled to a greater or less extent by the skill, care and methods used by the contractor. For this reason he is usually required to bear the expense of the same. "All loss or damage arising out of the nature of the work to be done or from the action of the elements or from any unforeseen circumstances in the prosecution of the same or from unusual obstructions or difficulties which may be encountered in the prosecution of the wor'k, or from any casualty whatsoever of every description, shall be sustained and borne by the contractor at his own cost and expense." D. Protection of finished or Partially Finished Work. — It is com- monly desirable to hold the contractor liable for the care of wholly 272 General Conditions of the Contract or partially finished work until the entire completion of the contract, and he should not be relieved in this matter on account of estimates or payments made on such work. "The contractor shall take all necessary precautions to protect all work done, or material furnished under this agreement, from injury by action of the elements or by the process of construction; he shall also take proper means to protect adjacent or adjoining property or property in any way en- countered or which might be injured by the process of construction to be taken under this agreement." "The contractor shall properly guard and protect all finished or par- tially finished work, and shall be responsible for the same until the entire contract is completed and accepted by the engineer. Estimate of partial payment on work so completed shall hot release the said contractor from such responsibility but he shall turn over the entire work in full accordance with the specifications before final settlement shall be made." "The contractor shall take all necessary precautions to protect all work done or material furnished under this agreement from injury by the action of the elements or the processes of construction, and on completion of the contract shall turn over the same and every part thereof in full accordance with these specifications." E. Hindrances and Delays. — Various unexpected hindrances and delays during the process of construction may add considerably to the expense of the work. The contractor is commonly required to sus- tain such extra expense without extra compensation. In writing such stipulation, care must be exercised to see that no injustice or unneces- sary hardship is placed on the contractor. When the progress of work is delayed from causes entirely beyond the control of the contractor, he is ordinarily entitled to an extension of time. In order to secure such extension, he is usually required to make an application in which he must set forth the causes of the delay. In granting such extensions of time it is usually desirable and cus- tomary to first secure the consent of the sureties on the contractor's bond, after which the contractor should be notified of the extension granted. It should also be stipulated that, in granting such extension of time, the party of the first part does not otherwise waive any rights under the contract. "No charge shall be made by the contractor for hindrances or delays from any cause (except where work is stopped by order of the parties of the first part) during the progress of any portion of the work embraced in this contract, but such delays, if due to no fault or neglect of the contractor, shall entitle him to an extension of time, allowed for completing the work, sufficient to compensate for the detention, provided the contractor shall give V'Q '^"'gineer immediate notice in writing of the cause of such detention. Conduct of the Work 273 The amount of the detention shall be determined by the engineer, and the extension of time shall not include unseasonable weather. In case said work shall be stopped by the act of the party of the first part, then such expense as in the judgment of the engineer is caused by such stopping of said work, other than the legal cost of carrying on the contract, shall be paid by the party of the first part to the party of the second part. "The reserve the right of suspending the whole or any part of the work contracted to be done when they shall deem it for the in- terests of the City of so to do, without compensation for loss to the contractor for such suspension other than extending the time of com- pleting the work: as much as it may have been delayed by such suspension; and if the said work shall be delayed for the reason that the parties of the first part do not own or have not obtained possession of land on which same is to be performed, then and in that case and every such case, the party of the second part shall be entitled to so much additional time wherein to per- form and complete this contract on his part as the engineer shall certify in writing to be just, but no allowance by way of damages shall be made for such delay. Neither an extension of time for any reason beyond that fixed herein for the completion nor the doing and acceptance of any part of the work called for by this contract, shall be deemed to be a waiver by the said commissioners of the right to abrogate this contract for abandonment or delay, in the manner provided for in the paragraph marked .... in this agreement." F. Defects, and Their Remedies. — (Work and material.) Work and mater'al furnished on a contract must be fully in accordance with the agreement and specifications. Work that has been done and is not of the quality required by a reasonable interpretation of the specifica- tions should be torn down or removed and rebuilt in accordance with the requirements. If the materials when brought on the site of the work are not foimd satisfactory and in full accordance with the agreement and specifications, they should be removed at once so that they may not be used in the work either by mistake or when the engineer is not aware of such use. m\ stipulation to this effect in the agreement is therefore advisable. "And it is further agreed that if the work or any part "thereof, or any material brought on the ground for use in the work, or selected for the same, shall be deemed by the engineer as unsuitable, or not in conformity with the specifications, the contractor shall forthwith remove such material and rebuild or otherwise remedy such work in accordance with the direc- tions of the engineer." G. Construction Plant. — Agreements are usually made with con- tractors for certain classes of work on account of their experience in such work and on account of their possession of necessary tools, ma- chinery and plant for the construction of the work in question. The agreement should therefore include a stipulation providing that the con- 274 General Conditions of the Contract tractor shall furnish the necessary tools, machinery, equipment and plant for the construction of the work to be done under the agreement, unless such tools, machinery, equipment, and plant are to be furnished by the party of the first part. "The party of the second part shall provide all labor, material, and machinery necessary in the prosecution and completion of this contract where it is not otherwise specially provided that the party of the first part shall furnish the same, and it is also to be understood that the party of the first part shall not be held responsible for the care or protection of any- material, tools or machinery or for any part of the work until it is finally completed and accepted. "The said contractor shall furnish the necessary scaffolding, ways and all necessary means and conveniences for the transfer of the material to its proper place, and for its erection; and it is also to be understood that the party of the first part shall not be held responsible for the care or protection of any material or part of the work until its final acceptance." § 155. Police and Sanitary Regulations. — Certain restrictions are usually desirable in order to enforce satisfactory police and sani- tary conditions and to prevent trouble from the use of intoxicants on the work. The latter is especially essential when the work to be done is isolated from communities where liquor is sold under license. Only three brief specifications of a general nature are here given as examples. It is frequently necessary to make exact regulations which will cause the contractor considerable expense, especially where large works are to be constructed in connection with the water supplies of large cities. In such cases the specifications should be fully elabo- rated in order that the contractor may be completely informed as to the expense which will be involved because of the sanitary regulations. A. Sanitation. "Necessary sanitary conveniences for the use of laborers on the work, properly secluded from public observation, shall be constructed and main- tained by the contractor in such manner and at such points as shall be ap- proved by the engineer, and their use shall be strictly enforced. B. Intoxicants. "The contractor shall neither permit nor suffer the introduction or use of spirituous liquors upon or about the works embraced in this contract or upon any grounds occupied by him." C. Contractor's Buildings. "The building of structures for housing men, or the erection of tents or other forms of protection will be permitted only at such places as the engi- neer shall provide, and the sanitary condition of the grounds in or about such structures shall at all times be maintained in a manner satisfactory to the engineer."

CHAPTER XV PREPARATION OF SPECIFICATIONS § 156. Importance. — The preparation of proper specifications necessary for a clear understanding of the nature of machinery, sup- pl'es, or material to be furnished or work to be done under a contract, is as essential for such work as the plans for the same. Each is ex- planatory of the other, each often incomplete without the other, and unless each is carefully and properly prepared, many disputes and mis- understandings are apt to arise, frequently resulting in expensive liti- gation. From such specifications, bidders not only get their information of the nature and amount of the work they will be called upon to do if this bid is accepted, but they may also form some idea of the fairness of the parties who have prepared the plans and specifications, and of the treatment they are liable to receive during the progress of the work. In many cases these papers are the only introduction of the bidder to the work and to the m.en with whom he is invited to do busi- ness. It is self-evident therefore thpt in the preparation of such specifications, absolute clearness of details and fairness of intent are essential to secure satisfactory proposals and proper work. Any specification that is indefinite, indeterminate, ambiguous or useless will involve uncertainties and result in the addition of certain sums by the bidder for self-protection which sums will invariably be far in excess of the actual cost which would result from a definite and exact requirement. Any specifications, therefore, which are arbi- trary, unfair or unnecessarily severe, give a bad impression of the engi- neer, attorney and principals and usually involve either a refusal to bid on the work or additions to the price bid to offset the unwarranted treatment to be expected under such specifications. A specification is not the place to show the extent of the engineer's knowledge, but it is the place to show how clearly and exactly he can describe the essential and practicable limits of the qualities of work and material needed for the end in view, how well he can protect his client by definite and proper requirements, and how fair and just he will be in his treatment of contractors. § 157. Use of English. — In the writing of specifications, all that has been said about the use of English applies with special force. The Importance of Specifications 279 language used should be clear, accurate, and exact. The technical terms or vernacular common to the trade to which the specifications apply, may be used, but they must be understood and used correctly. When used they must be defined or be used in the sense which they have acquired through common or local usage, the basis on which they will be legally interpreted. In the writing of contracts and specifications everything^ should, if necessary, be sacrificed to clearness. In reports and papers, for the sake of euphony, it is frequently desirable to substitute other words more or less synonymous in order to avoid repetition. In contracts this should be avoided ; words are almost never exactly synonymous, and in contracts and specifications the word having the exact meaning should be used as frequently as necessary. In such papers, it is also desirable to express the idea to be conveyed in the clearest possible way, and repetition of the same idea in dififerent words, if it adds to clearness, is not regarded as tautology. Care must be taken however to see that repetition does not obscure rather than clear up the idea to be conveyed. The language must not have a double meaning, and where a subject is described in general and also in particular, care must be exercised to see that the ideas duplicated are identical. In the Bronx Valley sewer contract, involving $2,000,000, the engi- neer described concrete to be used as a 1:2 4 mixture. He then spe- cified that a "batch" of concrete should consist of one barrel of cement (3.85 cu. ft.), two barrels of loose sand (6.50 cu. ft.), and four barrels of stone (13 cu. ft.). The contractor under the last description was required to mix the concrete in the ratio of i : 1.69 13.38, on the basis of the volume used, or even richer on the basis of the volume of loose cement. An action was brought for $36,000 on account of the excess cement required.^ In ordinary conversation and in most writings, the words used have a sufficiently clear meaning to convey our ideas for general pur- poses, for often no great degree of accuracy is necessary. In the writing of specifications, however, these same words are found to be indefinite, and must be defined and qualified to bring out the limited meaning in which they are or should be used. The young engineer is apt to assume that the words he uses have a single and definite meaning and is greatly surprised to find the language he has used and which conveyed to his mind a very definite idea, is susceptible of numerous other interpretations. 1 See the Engineering Contractor, Vol. 2, p. 83. 280 Preparation of Specifications In practice, the meaning of every term or expression should be analyzed, and whether or not it may have other than the meaning which it is intended to convey, determined. Not only is this analysis necessary, but it is also desirable to consider whether under the con- tingencies of construction, where perhaps unforeseen conditions arise, the terms may not have still other meanings, or perhaps prove quite inexact and indefinite. For example : The word "day" may mean the calendar day ot 24 hours ; the working day, omitting Sundays and holidays ; the work- ing day of ten hours : or the shift of twelve or eight hours. The term "ton" may mean the long ton of 2,240 pounds or the short ton of 2,000 pounds. The term "cord," commonly meaning 128 cubic feet, may, by local usage, mean 100 cubic feet. The term "perch" as applied to the measurement of stone work varies radically by local usage from place to place. § 158. Clearness. — Clearness in all details, both in plans and specifications, is a protection both to the owner and to the con- tractor, as in one case the contractor is unable to do improper work or avoid the execution of essential features, and on the other hand he is enabled to understand exactly what is desired by the engineer, and can regulate his bid in accordance therewith, without the addition of a percentage to cover uncertain work which he may be obliged to do but which is not clearly specified. Nothing is gained to the party letting the work by uncertainty in the understanding of what is de- sired, for if such uncertainty exists a careful contractor will add a percentage to cover such contingencies, while an unscrupulous con- tractor* will take advantage of such uncertainties to secure the con- tract and depend for his profit on his ability to avoid the execution of such portions of the work. Specifications not only describe the character of the work but also serve as the instructions to superintendents and inspectors as. to what requirements they are bound to enforce. It is therefore de- sirable that the specifications should be susceptible of a literal interpre- tation not only for a clear understanding between the two parties to the contract but also that the inspectors or superintendents in charge of the work shall know what requirements to impose. Where much is left to the engineer's judgment, or where unnec- essary or practically impossible specifications are imposed (which is always undesirable and inexcusable) friction may perhaps be avoided if the engineer is experienced and is continually at hand to give his in- terpretation of obscure clauses, or his permission to disregard inexped- Clearness 281 lent requirements. An inspector has no such prerogative, unless the same has been especially delegated by his superior and must usually insist (unless fully instructed by the engineer, which should always be, but seldom is, the case) on the fulfillment of the letter of the contract. When the inspector does insist on carrying out an irrational specifica- tion, and an appeal is taken to the engineer, if experienced, he must decide in favor of a reasonable interpretation of the specifications which he has prepared. In so doing, the engineer must reverse the decision of the inspector, to his great embarrassment, and to the injury of his confidence in his instructions (the specification), and of his future use- fulness. Clearness and exact language in sufficient detail to meet all reasonable contingencies and suitable for literal interpretation, will not only prevent disputes but will add to the efficiency and effective- ness of supervision and inspection. In order that a specification shall be clear and definite, its para- graphs and clauses should be arranged, so far as practicable, in logical order. Each element should b:^ discussed completely and in detail in a single paragraph or sentence devoted solely to that single feature, and when fully covered should not again be mentioned unless necessary for defining its relation to other features. More than one element should seldom be described in a single paragraph, as such reference tends to- ward obscurity. An extreme case of obscurity is illustrated by the following ex- ample '?■ "All timber standing where levee is to be constructed may be held by the contractor as his own, and he will be allowed an excess of 25% price per cubic yard for filling said muck ditch as in the levee embankment; also the contractor will be required to add 10% to the height of levee above grade line to allow for settling of same." Here are apparently three distinct subjects treated in a single sentence, and so treated as to leave the reader somewhat in doubt as to the idea intended to be conveyed by their author. Each of these subjects not only would have been more clearly covered by a dis- tinct sentence, but should have had a paragraph devoted to its specific purpose. § 159. Brevity. — While it is important that every element of the contract shall be clearly, completely and exactly described, it is also important and essential for clearness that such description shall be as brief as is consistent with a complete and exact description. 2 See Eng. News Sup. Dec. 31, 1903, p. 381. 282 Preparation of Specifications A specification is not a treatise on the subject under considera- tion, and should not be used to impress the chent. or contractor with the profundity of the engineer's knowledge of the subject. Only those characteristics or features should be specified which are essential in order to secure the results desired. Any paragraph, sentence, or word which can be omitted without material efifect on the complete under- standing of the subject should be omitted. The introduction of clauses in the specification which specify noth- ing except perhaps the uncertainty of the engineer's knowledge of the material or labor to be done are exceedingly undesirable and should be carefully avoided. For example, in many specifications for the foundations for brick pavements which were formerly in vogue in the Upper Mississippi Valley in which the foundation consisted of broken stone, filled with sand and properly rolled, this specification was com- monly inserted : "The sand shall be rolled, with constant light watering to avoid lick- ing up." What was meant by the latter portion of this clause has always remained a mystery. Possibly its originator had an idea which he thus defectively expressed ; others, evidently not knowing what it meant, adopted the clause for fear they would otherwise prepare a de- fective specification. Again, a clause relating to the concrete mixer provided "Mixer must be of a size proportionate to the size of the batch mixed," and in the same specification in relation to forms : "The contractor may adopt any suitable system of moulds for the con- crete in place, provided the same be approved by the engineer. The moulds may be fixed or movable, but must be rigid when in place so as to form a concrete accurately." s Neither of these clauses has any apparent meaning, or at least no meaning which would not be covered by a specification for "a good and workmanlike job." § i6o. Indefinite Specifications. — Carelessness and ignorance of the detailed requirements, which should be included, often lead to in- definite specifications. Such specifications are also sometimes inserted with dishonest or vicious intent. There is often a temptation to write such specifications rather than to take the trouble to consider and to determine the necessary requirements, at the time the specifications 3Eng. News Sup., Vol. 51, p. 257. Indefinite Specifications 283 are being prepared. As it is usually provided that the engineer shall interpret or explain any causes not clearly stated, there remains an opportunity for the engineer to decide the matter later, and this also involves an uncertainty and a chance for a considerable variation in expense. Such uncertainties may be and sometimes are used for the purpose of dishonest favoritism. Such uncertainties are manifestly unsatisfactory and unfair, not only to the contractor but to the client of the engineer as well, for they almost always add unnecessary ex- pense. It is only through ignorance, carelessness or dishonesty that specifications are left so indefinite that the contractor can not know exactly what is expected and required, or those which are unnecessary or undesirable are included. For dishonest purposes, specifications are sometimes drawn so in- definite that no bidder can determine what is required, unless he has inside information, and so many matters may be left to the decision of the engineer that no contractor, unless he knows he will be unduly favored, dare bind himself to the uncertainties involved. For exam- ple, in the specifications for a proposed power house for a state insti- tution,* the following stipulations were embodied : Under the heading "Violation of Contract," the architect was given authority to notify the contractor in writing and within 24 hours after the serving of the notice, the contractor should cease work ; the architect was then to have full authority to immediately purchase any- thing required and take possession of all the materials on the ground or built into the work, and the contractor or bondsman was to meet all bills. While such provisions are both illegal and absurd, no con- tractor would sign a contract containing such a clause without realiz- ing that a law suit might be necessary in order to maintain his rights. In another clause relating to changes, it was specified that in case any work was not in accordance with the specifications, the architect would be empowered to accept such work or material and make such a reduction in the contract price as he may determine, which reduc- tion was to be "final, conclusive and without appeal," another absurd and illegal requirement involving, however, the possibilities of favoritism or a suit at law. In relation to extra work, the following unique and unfair pro- vision was specified : "The contractor hereby agrees to furnish such materials and to perform such labor as extra work and agrees to ac- cept in full payment thereof a price which shall be fixed by the archi- i See Eng. News, Vol. 54, p. 603, 284 Preparation of Specifications tect and the board of trustees previous to its commencement." It is quite evident that such a power might work great hardships and per- haps financial ruin to an unfavored contractor, while a favored con- tractor would profit unduly. Numerous other similar arbitrary and uncertain provisions were included, all of which either indicated carelessness, ignorance and un- fairness or a desire to shut out competition, and to limit the bidding to some favored parties. The writing of a definite specification, however, is not as easy as may be assumed. A specification which may seem entirely definite may prove indefinite through the various conditions under which it may be exercised. For example : Engineering News, commenting on indefinite specifications, calls attention to the following: "Specifications (for concrete) for the most part read somewhat as follows : 'Concrete shall be made of one part by volume of Portland cement, 2i/^ parts by volume of sand, and 5 parts by volume of broken stone.' "A specification worded like this often becomes a fruitful source of controversy, for there is a great difference in the volume of cement depending upon whether it is packed in a barrel, shaken down in a measuring box, or merely cast loosely into such a box. It is a ques- tion for the engineer to decide whether loose or packed measurement will be required, but having decided he should be explicit in writing the specification. The following is a good example of clearness : 'In preparing mortar and concrete, the cement, sand and stone will be mixed in the proportix)n by volume hereinafter specified. The cement shall be measured when compacted so that 380 lbs. of dry Portland cement have a volume of 8.6 cu. ft. The sand and stone shall be measured when not packed more closely than by throwing it in the usual way into a barrel or box.' " (See Eng. News Sup., Vol. 50, p. 269.) § i6i. Indeterminate Specifications. — When the amount of ma- terial or work to be done under a contract is expected to be small, it is customary with some engineers to cover the same with only a brief clause in which the work done and material furnished are to be "as the engi- neer shall direct." This practice is less objectionable when only a limited quantity of such work or material is to be furnished, but as in most cases there is an uncertainty as to the amount, the practice seems entirely inexcusable. It may be regarded as proper to give no great amount of space to the specifications for a certain class of material or work where only a Indeterminate Specifications 285 small quantity is to be used, but while brief, the requirement should be clear and exact. If the work is worth doing, the contractor has a right to know the exact requirements before he bids for the same, and should not be held subject to the uncertain requirements of an engi- neer, possibly unknown and inexperienced. The following are exam- ples of such objectionable practice : "First class compound arch masonry will be laid in mortar. The thick- ness of the arch, the length and thickness of the stone forming the arch, will be such as the engineer shall prescribe." Also, "Concrete is to be made of such material and in such proportions as to material and in such manner as the engineer shall direct." s Even when an attempt is made to draw briefly such specifica- tions, it sometimes -occurs that the engineer may, in his haste, specify the material of a greatly superior quality to that which is actually needed in the work. This may prove .serious if through an unex- pected increase the quantity required is actually large. For example, in a specification for sewers in which only a limited quantity of tim- ber would probably be needed for the foundation work, it was speci- fied : "Such lumber as is required shall be of a suitable character for the pur- pose intended, of straight grain and free from all defects." The first part of this specification might have an entirely different meaning from the last portion Kyi the same, for in few cases would timber "of straight grain and free from all defects" be needed. A cautious contractor, under such a specification, would bid a price which would assure him a reasonable profit under any conditions, while a careless contractor, relying on the first clause of the specification, might sustain a serious loss if a large amount of such material were used. § 162. Ambiguous Specifications. — Unnecessary or unreason- able requirements are always ambiguous and are uncertain as to what is actually desired, and what will actually be required by the engineer. Under such conditions, responsible contractors will add materially to the price for the work done under such specifications. Not only does this unnecessarily increase the cost of the work, but such specifications also brand their maker as ignorant of the practical requirements of the work, and are a notice to unscrupulous parties that the writer of the specifications is one who may perhaps be manipulated or bluffed into reasonable requirements, or even to extremes in the other direction. It is only too easy to prepare in the office specifications which are im- Eng. News Sup., Vol. 51, p. 258. 286 Ambiguous Specifications possible to carry out in the field, or which, if carried out, will prove undesirable or expensive. Specifications that cannot be reasonably enforced except under particular and peculiar circumstances, should be eliminated for where they are included they practically must be ignored except where an absolute necessity for their enforcement arises. This calls for an arbi- trary decision by the engineer which a subordinate can seldom be per- mitted to exercise, and in the exercise of which by the chief he is left open to criticism. For example, in the specifications for concrete, the following clause has frequently been inserted : "Concrete shall not be dropped into place through a greater distance than one foot." e A specification of this sort is usually wholly impracticable and should be required only where some injury, possibly by separation of material or injury to new work, might make such an unusual precaution absolutely necessary. Such a specification, therefore, should not be applied to the entire work, but only to the conditions in which such requirements are neces- sary, and it would seem desirable to introduce a longer specifi- cation in which the methods of depositing the concrete under various conditions should be restricted as far as necessity seems to demand. These extremes should be avoided by the engineer. He should specify only such requirements as are necessary for the completion of the work in the manner desired. § 163. Arbitrary Specifications. — While it is necessary for the engineer to be able to exercise such control over the work as will enable him to secure its proper performance and completion, it is unwise and unsafe for him to endeavor to exercise unneccessary and abitrary con- trol over any part of the work. If the contractor is to be held responsi- ble for the work, or for the results obtained, or as to time of comple- tion, safety to the public, etc., he must not be relieved of responsibility through arbitrary specifications, by means of which the prerogatives of management may be usurped by the engineer. An extreme case of such usurpation is shown by the following extract from a sewer specification : "The contractor must employ a competent mechanic, selected by the engineer, who understands and speaks English, and not a common laborer, to make the joints of the pipe sewer." 7 c Eng. News Sup., Vol. 51, p. 257. 7 Eng. News Sup., Vol. 51, p. 149, Arbitrary Specifications 287 A common but extremely arbitrary requirement which may be ex- ercised to a contractor's serious disadvantage, and is therefore unde- sirable, is as follows : "The contractor shall commence and prosecute work at such points, at such times and with such forces as the engineer may direct." « Such a specification is seldom necessary or desirable. The inser- tion of a time limit clause and of such requirements as to when and where the work is to be begun and prosecuted as may be necessary, wi!l relieve all doubt, and render impossible arbitrary persecution dur- ing construction. Too great and arbitrary authority by the engineer may result in his assuming for his client responsibilities which should be placed on the contractor. For example : "Before blasting, the contractor must procure a written order from the engineer. Blasts shall be covered with timbers heavily chained together. Caps or other exploders shall in no case be kept in the same place in which dynamite or other explosives are stored; and, in general, the precaution against accidents from blasting shall be entirely satisfactory to the engineer. The contractor shall be liable for all damages to persons or property caused by blasts or explosives." a If under this clause, the engineer is called upon to specify the precautions to be taken and should an accident occur in spite of the precautions taken, the contractor may reasonably claim that he had acted as servant of the engineer's client and not as an independent contractor, and is therefore blameless. § 164. Unfair Specifications. — Occasionally in specifications it wouM seem the purpose of their writer is not only to protect his client in every legal way but also to hamper the contractor by unfair and un- called for restrictions. Such restrictions can result only in unneces- sary expense as they must of necessity limit competition, make the contracting parties doubtful of the good faith of the party preparing the specifications, and suspicious of the treatment which he will ac- tually receive should he be awarded the contract for the work. Such clauses shouM be eliminated entirely as they have no place in the con- tract. It is, and should be, the purpose of every attorney or engineer who may be preparing a contract to see that his client is entirely and fully protected, but anything beyond this can give only unsatisfactory results. It is usually desirable when letting a contract which is finally placed in the hands of a responsib^.e party to prohibit the assigning of s Eng. News, Vol. 51, p. 149. 9 Eng. News, Vol. 51, p. 65. 288 Preparation of Specifications the contract to other parties who may not be fully satisfactory. The restrictions, however, should not be so made as to prevent the con- tractor from being able properly to finance his work by allowing its use as security for money borrowed for its execution. The following clause is an extreme case of this kind. The clauses written are en- tirely unfair, uncalled for, and may be used as a club for the purpose "It is mutually understood and agreed that if the contractor shall as- sign or transfer either absolute or conditionally by order or otherwise, the compensation or any part thereof to which he may become entitled under the contract before such compensation is actually earned, the city may, for that reason, cancel the contract and retain all compensation at the time of such assignment or transfer due or owing to the contract; or the city may, at its option, recognize any such assignment and transfer as valid. The option of the city in that regard shall be exercised by the commission of public works, and the recognition of any assignment or transfer as valid shall not preclude the city from cancelling the contract on account of any other or subsequent assignment or transfer. The contractor agrees not to so assign or transfer his compensation, or any part thereof. "And it is also mutually understood and agreed that the city may, at its option, declare the contract in default and cancel this contract, in case proceedings in bankruptcy are instituted by or against the contractor (or either of thQm, if there is more than one), or in case proceedings supple- mentary to execution are instituted against the contractor (or- either of them, if there is more than one) ; and if the city shall so cancel the con- tract, it may complete the work or improvement as herein elsewhere pro- vided. Such option shall be exercised by the commissioner of pubUc works." 10 It is always desirable, when possible, to determine in advance the character of all work required, and to describe it so clearly that an in- telligent bid for the same may be made by the contractor. In underground and subaqueous work it is sometimes impossible to determine in advance just what character of work will be necessary to secure the desired results. When such is the cond'tion, any work which may be required to bring about the desired results should be regarded as extra work, and paid for as such. Any attempt to force the contractor to perform such work at his own cost and expense is not only unfair, but will usually result in high bids and unnecessary expense. An example of an unfair specification of this class is as fol- lows: "Whenever the bottom of the trench is not sound, the contractor must furnish and put in place, without expense, good or suitable material; and when it is considered necessary by the engineer, the contractor shall lay a foundation of timber, without extra expense.

Unfair Specifications 289 The intelligent contractor will, of course, add a sufficient amount to cover fully the probable cost of any work which might be required under such a specification as the above, and the engineer's client will pay more than the fair cost of such work. To ask a contractor to assume all risk of conditions and then to assume the risk of what an obviously unfair engineer may think necessary to provide for such un foreseen conditions is, to say the least, unwarranted. In specifications for work which is covered from sight, not easily reinspected, and not open at all times to ready examination, it is de- sirable to provide that the engineer may if he desires uncover and open up for his personal examination any work supposed to be com- plete. In such case it is usually provided that if the work is found to have been constructed in accordance with the plans and specifications, the cost of such examination and of any necessary repairs shall be at the expense of the engineer's client; but if the work is found faulty in any particular, it shall be replaced and repaired at the expense of the contractor. Such a clause, permitting re-examination at any time, discour- ages any attempt at introducing poor work or material either in the absence of the inspector or by collusion, and is fair and just for it in- volves no expense to the honest contractor, while it means the possi- bility of an expense to the dishonest contractor greater than any pos- sible saving through defective work. An unfair clause of this general character which would undoubtedly cause an unnecessary increase in the cost of work on account of the uncertainties involved, is as follows : "The engineer must be permitted to remove sucli portions of the work as he may from time to time think necessary, for the discovery of improper material or workmanship, and the contractor shall restore such work at his own expense." 12 It is evident that with such a clause an engineer may greatly an- noy a contractor and add materially to the expense of construction. Such a clause is not only unfair, but savors of dishonesty as by waiv- ing, such examination for a favored contractor, the cost of construc- tion might be greatly reduced. § 165. Unnecessary Severity. — In drawing specifications for a material only the average requirements which characterize a good ma- terial of the class desired should usually be embodied. It is undesir- able to make the limiting requirements too severe, unusual or extrava- gant, as such requirements may add materially to the expense, pre- vent intelligent bids by driving responsible contractors from the field, i2Eng. News. Sup., Vol. 50, p. 3G5. -?C* 290 Preparation of Specifications prevent the execution of the work, or involve a confession of error and have to be modified to the embarrassment of their writer. Too often the minimum hmits of a specified test are fixed at or near the maximum that has been secured from tests of the best of similar ma- terial. Frequently the results specified are impossible to obtain on the average, especially when a material is new on the market. Such severe requirements are usually in error and are seldom if ever neces- sary. The requirements for a good average material are more readily enforcible, and any additional safety required should, if possible, be 'secured by improvement in design. In the early days of brick paving, when the number of paving brick factories was still small, a test of paving brick from one of the smaller factories showed that the best class of material would not ab- sorb more than i^ per cent of water. Based on these tests, it was suggested that specifications for this material should place this limit as the requirement for brick for paving. At the particular time in question, the factory mentioned could not have supplied more than one- half million brick per year, and few if any other factories were, at that time, turning out brick which would comply with such a specification. Nevertheless such a specification was adopted for a paving contract involving about six million brick, and had to be waived before the construction of the pavements in question was possible. § 1 66. Specifications for Criticism. — The student, should con- sider one or more of the following specifications, and both criticize the specification as written and rewrite the specification so as to assure proper results or to express the meaning (which should have been ex- pressed) in clear and unequivocal language.

Breadth of Knowledge Necessary. — Engineering specifi- cations may cover almost any phase of industrial activity, and it is ob- vious that no individual can, from his experience and immediate knowledge, be prepared to write suitable specifications for all of the multitude of engineering and architectural works, machines, materials and processes for which such specifications are sometimes needed. Even where the specifications are for matters within the experience and knowledge of the individual, and even though he has frequently prepared similar papers, the difference in conditions, the advances in the art, the improvements in methods, and the special economies possible, usually require thoughtful preparation and a readjustment of the ideas that have previously been embodied in such papers. In almost every important work, new conditions and new require- ments may mvolve detailed methods not fully familiar or possibly even quite unfamiliar to the engineer in charge, and he is obliged to pre- pare a specification for an object or result somewhat beyond his expe- rience. In all cases, and particularly in the case last mentioned, the engi- neer must know either by experience or by investigation, the nature of the material and processes best adapted to the particular case at hand, and the limitations and restrictions that it is desirable and com- mercially possible or practicable to specify for the guidance in fur- nishing the material and doing the work of construction. Everv source of information should be utilized, and even these will often be round too limited for his full information. § 168. Detailed Information Needed. — In the preparation of technical specifications, it is essential that the engineer should pos- sess a comprehensive and detailed knowledge of : First. The qualities and characteristics of the various materials to be used and the practicable limits to which the qualities necessary for the work in question should be restricted. Second. The usual and practicable methods of performing the work to be done in such a manner that it will be completed without unnecessary expense and in a manner satisfactory for the purpose which it is to fulfill. Detailed Information 295 Both requirements presuppose a somewhat broad and complete knowledge of the material and processes considered. Such a knowl- edge is acquired only by extended study, observation and ex|perience, and is not usually possessed by the young engineer or by an engineer who has been called upon to undertake work in lines somewhat differ- ent from his previous practice. In such cases, systematic study, in- cluding observation and investigation, can only partially take the place of the knowledge gained by experience, and without systematic study such specifications cannot be properly prepared. In many cases, experience is absolutely necessary, for the necessary requirements which should be included in correct specifications are not always suffi- ciently elaborated in available technical papers or books, nor is it al- ways practicable to obtain a sufficient knowledge of the same through limited observation and investigation. Third. The ability to designate in detail the composition or ele- ments of the material or processes and the methods to be used for their proper production and utilization or the ability to design in de- tail the structure, machine or plant contemplated. Fourth. A knowledge of the methods ordinarily employed by the mechanics or operatives in the manfacture of the product or machine and in the construction and operation or maintenance of the plant or structure. Fifth. The experience which will foresee the necessary materials and methods to be employed, difficulties to be overcome, and contin- gencies to be met in the work. The more complete the knowledge of the subject, the better the specification, provided the engineer has the ability to express his knowledge in clear and exact language. No engineer can evolve from his inner consciousness adequate specifications for engineering work ; and even after extended exper- ience, the intelligent engineer will frequently find ways in which his specifications can be materially improved. Extended study, observa- tion and investigation must therefore precede the preparation of any specification, and especially in lines which are new to their writer. § 169. Outline. — The detailed requirements of the specifications for even a single fundamental material or process are seldom so sim- ple that they can be kept clearly in mind for the purpose of specifica- tion writing without danger of serious omissions. In the preparation of specifications for engineering and architectural works, the materials are so many, the processes so numerous, and the various parts and 296 Technical Specifications divisions are so nianifoM that some material, process or part is apt to be overlooked and omitted unless special precautions are observed. Reliance on the memory to retain all these matters is inexpedient, as most engineers have experienced to their great embarrassment. From similar experiences, the author was led to adopt the analytical method here outlined, which he has used with satisfaction in his prac- tice for a^.most thirty years. The general plan to be pursued in the preparation of these out- lines is to divide the work to be done into its various elements, and to set down in detail ail materials and process which must be included, still further subdividing and analyzing the essential features or re- quirements of each. In the cases of fundamental material or processes, the qualities or operations that should be limited or controlled should be similarly differentiated, classified and outlined. The engineer should keep his note book constantly at hand when considering an improvement, whether in the office, the field, or the drafting room, and carefully note such points as he desires to intro- duce in the completed work, and embody them in his outline and specifications. The purpose of the analysis suggested is to arrange in a logical order the detailed subject matter for any given specification, covering in each case completely, or as nearly as practicable, the entire subject to be considered. In general such an outline should include all items that should ordinarily be embraced in a specification for similar ma- terial process or work. The outlines should be sufficiently complete to cover all ordinary conditions and requirements and in their use they should be carefully scrutinized to see that they include every item necessary for each particular case. With this ana^.ytical method of specification writing, collections of specifications of able engineers on various important works are of great value as suggestions, and will greatly facilitate the preparation of such outlines. A careful analysis of the work to be done or material to be fur- nished under any contract, is essential to rapid, accurate and suc- cessful specification writing. In the actual writing of specifications, all of the items in a com- plete outline will seldom be used for the particular work in hand, and often a brief memorandum may embrace all that is essential or de- sirable to mention. In practice, for each particular piece of work for which specifi- cations are to be prepared, a special outline in logical order may be The Outline 297 first drawn up in which should be inckided all items necessary for the particular work. From a correct outline of this kind the specifications can be drawn with little chance of omission of important matters. After a correct outline is drawn, the specifications under each heading may be written, or clauses from such other specifications as the engineer desires to use as models, may be used so far as they apply to the work in hand. It is essential, however, that their bearing should be carefully scrutinized, and no specifications should be introduced which do not distinctly apply to the work in question.^ § 170. The Use of Published Specifications. — In the preparation of technical specifications on lines that differ somewhat from those embraced in the experience of their engineer, the usual method has been to select as a basis for the new specifications, similar specifica- tions which have been used on other more or less similar work, and which are judged by the engineer to be satisfactory. An inteliigent study and analysis of specificat'cns which have already been prepared for similar work, especially where the exper- ience of their author renders them authoritative, is of great value and importance. There is no better source of information than well prepared speci- fications nor a better method of study than by a comparison of the practice of a number of experienced engineers as expressed by their specifications, and no better method of preparation than the adoption of well considered phrases and entire clauses that are really applicable to the case at hand. The error which commonly follows this practice lies in the abuse of such a method, and such errors can be overcome and this means of acquiring information utilized to advantage only by a full and careful analysis and comprehensive study of the subject. There is no way of accomplishing the object sought without hard and unremitting study and investigation, and professional success is de- pendent on an appreciation of these requirements no less than on other professional knowledge and experience. The rewriting of a well prepared clause which clearly and defin- itely specifies the qualities or limitations desired in order simply to effect originality is not advocated. Originality in specification writ- 1 Similar outlines to those suggested are published: 1st. In Sweet's Catalogue of Building Construction. (See checking list for specifications and estimates.) 2d. In The Engineering Catalogues and Specification Digest, Iscrc'^. by the Engineering Magazine, (See Specification Digest.) 298 Technical Specifications ing is not a desirable object. In most cases the more original a spec- ification is, the poorer it is. Well established precedent is a safe guide to follow, especially when proceeding beyond the domain of per- sonal experience, but it is essential to determine that a precedent is 7vcll established and is a proper precedent for the condition at hand. In selecting for use specifications prepared by others, they should be modified as the conditions demand. This method has given and will give good results by careful discrimination and intelligent study, but it too often degenerates simply into copying wnth slight changes, the clauses prepared in previously executed work, the importance of which frequently differs from the work on hand and the conditions of which often vary largely from the work for which the new specifica- tions are to be used. To prepare a good specification will therefore require much more than even the judicious copying of other specifi- cations. A well and properly written specification will seldom apply in detail to other than the work for which it is prepared, and the use of such specifications on entirely diflferent work under radically different conditions and without careful initial study and consideration of their application in detail, can lead only to unsatisfactory results and is inexcusable. The unintelligent copying of such specifications should be studiously avoided. Such a method of preparation, which is alto- gether too common, is apt to bring embarrassment and shame on those who follow it. If the engineer is in too much of a hurry or is too indolent to study his subject and to inform himself properly, he is quite sure to copy those clauses which he does not understand, as such clauses will appeal to him as possibly highly essential for the perfection of his specifications, while frequently they will have no bearing whatever on his particular case, and the introduction of a clause not pertinent to the object at hand is a notice to contractors and manufacturers that their author is ignorant of his subject. In the careless use of this method of preparing specifications, cer- tain specifications are often selected only because they have been used on important work in other places and have to the unsophisticated engineer, a learned sound and not because there is any necessity for their introduction for the particular work in question. In this manner certain specifications are sometimes copied and recopied until they have lost any shade of meaning ; and in other cases, specifications are copied which may have no application whatever to the case in hand. Published Specifications 299 While the insertion of useless specifications is objectionable, inas- much as they display ignorance of their writer in regard to the work at hand, yet they are ordinarily meaningless and their insertion is not so serious as the) omission of important specifications, which is per- haps a still more common occurrence. One of the dangers of copying a specification is that the specifica- tion may be incomplete unless the drawing of the work, which is an integral part of the same, also be considered. Dimensions shown on the drawings are seldom repeated in the specifications; hence if the specifications are carelessly copied, without due consideration, they may be regarded as complete in themselves when such is not the case. Take, for example, the following clause for a pavement : "Upon this sand cushion shall be laid a pavement of asphalt blocks. The blocks shall be 4" in width and 12" in length." It will be noted that the depth of the block is not mentioned, such depth being doubtlessly shown on the drawing to which the specifica- tions refer. § 171. Simple Specifications. — In the performance of the sim- pler forms of labor, and in the purchase of the simpler materials or sup- plies, and even of simpler and smaller machines which have become standard, the necessary specifications are often of the simplest kind. Simple specifications may require only a plain and exact statement of the conditions that exist and the general nature of the machine or structure required to satisfy those conditions. Such specifications re- quire no elaborate special knowledge in their preparation, but such knowledge may be required when bids are received in order that an intelligent choice may be made as to the manner and method in which they will be best fulfilled. The preparation of such specifications does require a complete comprehension of the conditions and the ability to outline them clearly and completely, so that manufacturers or contractors will know how the requirements are to be met. In order to permit of competition in matters wherein certain methods or details are controlled by or are peculiar to certain indi- viduals or firms, the specification must be left open and should require that the proposal be accompanied by manufacturers' or proprietors' specifications, defining in detail the material, machinery or construc- tion which it is proposed to furnish under a specific bid. In all cases, where the specifications are only general in character, the contractor may be required to furnish the detailed specifications 300 Technical Specifications and perhaps detailed plans with his bid, describing and showing therein the special details he proposes to furnish. Such specifications are usually requested under some general specifications, as follows : "The contractor shall furnish specifications describing in detail the char- acter of the work and material to be furnished by him under this contract. Such specifications, when accepted by the party of the first part and attached herein, shall be marked 'Exhibit . . . ,* and shall constitute an essential part hereof, and the work furnished hereunder must strictly conform thereto." § 172. Detailed Specifications. — As a design becomes more elaborate and the individual parts of a structure become more numer- ous or complicated, it becomes more and more essential that the speci- fications shall be complete and that the materials and method of con- struction of each part shall be described in detail, for with increased complications in design greater uncertainties arise as to the materials and methods of construction which must be used. The specifications are intended to fix these details beyond question, and to confine the character of the materials, workmanship, and design within necessary limits. The preparation of such specifications requires an extensive tech- nical knowledge of materials, processes, designs and construction, in- cluding a knowledge and appreciation of commercial conditions and limitations which may influence the cost and efficiency of the results desired. In some cases where detailed plans and specifications are sup- plied, it may be desirable to ask manufacturers or expert contractors, having special experience, to submit bids not only on the engineers' plans and specifications but also on special plans and specifications, embodying their own ideas and practice. § 173. Modifications of Requirements. — In the preparation of specifications, especially for public work, it is important that provisions should be made for such modifications in the methods which are to be pursued and the materials that are to be used as are likely to be re- quired, as any modification by the engineer in the strict requirements of the specifications are apt to subject him to severe although possibly unwarranted criticism. For example : in the specifications for con- crete or for placing the same (see Sec. 220), it is advisable if there is any chance that modifications in the character of the mixture or pro- cess will be desirable, to provide in the specifications for such modifi- cations and for the less or greater compensation to the contractor for the amount of work in which such modifications are made. The same rule should, of course, apply to all other materials and work in which modifications may become necessary. Standard Materials and Methods 301 § 174. The Use of Standard Materials and Methods. — Specifica- tions not only bind the contractor to perform his work in a certain manner, and to furnish material of a certain grade, but they also greatly influence the cost of the work and material furnished. In ordinary practice it is desirable to specify only such character of ma- chines, material, supplies or methods as may be found on the market and in general use. Unusual characteristics, modifications of stand- ard machines, and the introduction of new methods, should be speci- fied only when such unusual requirements are clearly needed to secure the best results and after an investigation has shown plainly that the additional expense involved is commensurate with the better results to be obtained. Neither the best nor the cheapest is uniformly desirable or ap- plicable, and the ideal quality for the specific conditions in immediate question should be the aim in each case. Unnecessary requirements and restrictions as to the quality or character of material and supplies or of unusual methods of construction will add unnecessarily to the expense involved and are a serious error. Such specifications are only too common and frequently result in unwarranted expense, serious trouble and sometimes in legal complications. § 175. Influence of Specifications on Material and Methods. — While it is largely true, especially in small works, that the engineer must use those materials, products and methods which are usual and available and have the endorsement of common usage, it is also true that all such commercial products are s^.owly but surely modified and shaped by the demands of the best practice. The manufacturer who offers a material or a machine which is not up to standard require- ments, must sell to the ignorant or to others at a considerable disad- vantage, for a reduction in price for an inferior article may sometimes compensate for lack of a higher degree of perfection. If a machine or material is found more or less unsuited for the purpose for which it is used, and that purpose is of importance, its users will soon demand such changes in its qualities as will make it more satisfactory ; and the engineer in charge of the designs, dependent upon its use, or of the plants in which it may be needed as a necessary supply, should investigate its quality, see in what ways it may be improved and pre- pare specifications which will bring about the required improvements. Such improvements can be brought about only by expert investigation and a full knowledge of the subject ; and the specifications must be made along practicable lines. 302 Technical Specifications The Altoona laboratories of the Pennsylvania Railroad are de- voted to such work, and the investigation and specifications, and the resulting betterments in materials and supplies furnished to that com- pany are examples of the best practice in specification writing.- § 176. Responsibility. — The more general the specifications, the greater the degree of responsibility which the contractor should be re- quired to accept. As the details are defined by the specifications, the contractor's responsibility must of necessity decrease, for neither morally nor legally can a man be held responsible for results which are entirely beyond his control. In fixing responsibility by means of tests and guarantees, the item of the expense involved must be carefully noted, for, especially in smaller contracts, such requirements sometimes involve a consid- erable extra expense. It is frequently better to purchase a standard article from a manu- facturer of known repute, from whom the engineer knows he can secure a machine which will give certain well-known results, than to purchase a similar article under unusual guarantee from unknown parties and then forego the test on account of the expense involved. Responsible manufacturers frequently refuse guarantees on small contracts unless the tests are made at their own factories, or unless the expense of such a test is covered by an additional compensation to meet the cost of making them. The contractor should always be held responsible for the class of workmanship and material desired, and his responsibility in these matters should be carefully covered in the specifications. § 177. Definite Requirements. — In the preparation of specifica- tions for materials, processes, machinery or works with which the engineer is more or less unfamiliar, there is always a tendency to cover ignorance by indefinite requirements. Indefinite specifications should, wherever possible, be carefully excluded from all specifications, and from machinery specifications in particular. If it is essential to specify limiting stresses in machine parts, then the limits should be specified in exact language, and they should not be specified to be "ample" or "sufficient." Such specifica- tions ar€ valueless for they leave the matter wide open for irrespon- 2 The Influence of Specifications on Commercial Products, by C. D. Dud- ley. Address Am. Soc. for Testing Materials, 1904. See Eng. News, Vol. 51, p. 592. Definite Requirements 303 sible manufacturers to do improper work, and trust to the ignorance of the engineer to pass it on inspection, while with reputable makers such clauses are wholly unnecessary. The question as to what the terms *'ample," "sufficient," etc., are intended to cover, must finally be decided if the machine is to be accepted or rejected on such a basis, and it will greatly aid in the clearness of the specifications if such questions are decided in the first place and the exact requirements inserted in place of the indefinite ones. General specifications in regard to workmanship must, from their nature, necessarily be somewhat inexact and indefinite, but when such clauses must be used they should be as carefully defined as pos- sible. When necessary such clauses may be embodied in the specifi- cations and defined by a specification somewhat as follows : "Whenever on account of the nature of the workmanship or material to be furnished, the specifications defining tlie same are, from the nature of such work or material, inexact or indefinite, and are specified to be 'first- class,' or 'satisfactory,' or by other terms in which the judgment of the in- dividual may vary, then and in that event, the engineer shall be the sole judge of the fulfillment of the same." Such a clause should, however, be used with care, as few con- tractors or manufacturers care to put themselves into the hands of an inexperienced or incompetent party. § 178. Standard Specifications. — Various technical societies and associations have from time to time adopted "standard specifications" for certain materials, processes and structures. In general, such spec- ifications have received the careful consideration of experts who have had much experience in the manufacture and use of the material and are the result of a very free and full discussion of the various prac- ticable requirements of such manufacture and use. When such spec- ifications are available for a material to be used in construction, their adoption by the engineer seems to be desirable unless the peculiar conditions of the case in hand make changes in the requirements es- sential. The standard specification and its equipments are usually w^idely known to manufacturers and contractors, and the cost of the material, as subject to such specification, is readily determined. Requirements more severe or radically dififerent from a well estab- lished standard may seriously afifect and render uncertain the prices which may be demanded. Departure from such standards should therefore be made w^ith care and only for good and sufficient rea- sons. 304 Technical Specifications As such specifications are often well known and widely published, it is seldom necessary to embody them in detail in the specifications prepared by the engineer, but they may be made a part of such specifi- cation by distinct references. Such specifications are : Specifications for Portland cement, adopted by the American So- ciety of Civil Engineers. Specifications for underwriters' fire hose, adopted by the Associ- ated Factor}' ]\Iutual Fire Insurance Companies. Specifications for structural steel, as adopted by the Steel Manu- facturers' Association. Other references to similar specifications will be found in the Bibliography at the end of this volume under the heading of Standard Specifications. With the development of the arts and the experience of time, these specifications are changed, and in referring to them the date of the adoption of the specifications should always be given. Such specifi- cations may be introduced into the contract by a reference as follows : "The material or work to be furnished under this contract shall be in strict accordance with the specifications for Structural Steel, adopted by the Steel Manufacturers' Association of (date), and which are hereby made a part hereof."

Fundamental Elements of Specifications. — Fundamental materials and processes are first introduced in the discussion of spe- cifications not on account of their simplicity but because engineering or architectural work is made up of a series of such elements, and proper specifications of fundamental materials, supplies and processes, united together in a complete and consistent whole, will constitute a correct description of the technical requirements. There are in fact no specifications more difficult to prepare than those for fundamental materials and processes. Their accurate prep- aration necessitates a complete and definite knowledge of elementary details not commonly possessed by any except those who have given the subject extensive study. As the various materials and processes are so numerous, a detailed knowledge of practicable limitations and the extent to which their qualifications should be modified and controlled in a specification is not the common knowledge of the engi- neer. Frequently such knowledge is not generally available and the im- portance of the material is not sufficient to warrant the expense of a sufficient investigation or of suitable tests and experiments to form the basis of a sound specification in which the composition, method of manufacture or specific test requirements can be intelligently and spe- cifically set forth. This is particularly true of new materials, proprie- tary articles and various supplies. § 180. Practical Limitations of Specifications. — The possibility of an intelligent specification depends on the existence of a certain amount of definite knowledge which can be clearly outlined, covering the composition or character of material, the methods of construction or manufacture, or certain test results which are to be obtained and which will actually indicate the character of the material. In the early development of any material, machine, structure or process an attempt is made to accomplish certain results in a certain way. The attempt is a failure and is abandoned, or it meets with greater or less success in accomplishing the object sought. In the latter case, various troubles arise as time passes ; early success may be followed by partial 306 Specifications for Materials failure with other and more severe conditions, and such failures may or may not be obviated by changes in composition, methods of manu- facture or design. The development may be successful under certain tonditions and a failure under others. In each case a knowledge of the limits of application and composition become gradually known and appreciated. The designer, manufacturer or producer acquires a cer- tain knowledge of the development and of the effect of variations in its composition or design on its utility under various circumstances, and such knowledge is not usually available to the purchaser or con- sumer except when the development has been extensively applied, and then only after a wide and comprehensive inquiry. The purchaser frequently acquires a very definite knowledge of the application of a material to his particular requirements, and especially the effects of time and use on its ultimate success. The producer, if his product is reasonably successful, desiring to introduce it for the broadest application while bettering his products as the demands require, is not likely to give the purchaser any further knowledge of the contingencies involved than his own interests war- rant. He is unwise if he permits the product to be used where failure will inevitably result, for such failure will prejudice its future use; but he must run certain chances of failure in order to extend the use of the products to new and untried fields. The purchaser secures the product which from his investigation seems most likely to give the results he desires ; he endeavors by in- vestigation, by preparing specifications and by requiring guarantees and tests, to protect his interests. These he must limit in accordance wnth the necessities of the case and the expense involved. He must assume certain risks or stand the expense of assured results which would frequently lead to great difficulty and unwarranted expense, es- pecially in a new product. Gradually the use of a product becomes more and more extended, other similar products arise and purchasers increase in number. The application of the product is widely dis- cussed, the difficulties in its use become known, the effects of design, of composition and of method of manufacture become appreciated. Under these conditions the product can be more or less controlled by specifications, for certain definite and fundamental knowledge becomes available to all on suitable inquiry. The product may become stand- ardized in its common application, and by reference to such standards easily limited by purchasers with normal intelligence and having even, relatively slight knowledge and experience. Limitations of Specifications 307 In the incept'on of the development no standards are possible ; a certain risk is necessary if the product is to be used and such risk is common both to the producer and purchaser, and must be divided in such equitable manner as the circumstances require. The producer desires to place his product on the market and to make it an ultimate success. His experience and his finances may per- mit of his warranty, and his reputation and responsibility may make such warranty acceptable to the purchaser. The warranty involves expense, replacements are necessary and damages may be involved, but finally experience is acquired, success more or less definite is es- tablished, the guarantees can be more and more limited or may become entirely unnecessary, for the product has become standard and its use within certain limits recognized as a practical success. It is evident that detailed specifications should be limited to those materials and supplies in the manufacture of which the composition, methods of manufacture and results attained can be intelligently con- trolled for a useful purpose. If the composition and methods of man- ufacture materially affect the results which will be obtained in the use of the materials, limitations of both composition and methods may be desirable; but if a knowledge of the effect of composition and method is not available, a specification in which an attempt is made to control these factors is useless or worse. It is evident that any specification which will involve unnecessary inconvenience or extra expense to the manufacturer will be undertaken only when the amount of the ma- terial required and the price that can be obtained make it worth while, and the extra expense will be warranted only by definite and positive advantages to be gained. § i8i. "To the Satisfaction of the Engineer." — As with every other subject, so in specification writing, it is much easier to deal with generalities in more or less vague and meaningless phrases and to finally limit the so-called specification by the requirement that the ma- terial or process shall be furnished or done to the complete satisfac- tion of the engineer. The engineer may not, and frequently does not know with just what details he will be satisfied. The matter is often uncertain in his own mind and he relies on the chances of his ascer- taining by study or through professional inspiration the limitations which will permit him to pass upon the matter with possible credit when the emergency for a necessary decision arises. The contractor, on his part, takes the chance on the probability that the engineer will be satisfied with reasonable requirements. 308 Specifications for Materials Where the material or process required is only a small portion of the complete construction, the specifications need not be elaborate, and the requirement that it be "satisfactory" may be a reasonable one. Where, however, the material constitutes a large and important part of a contract, it is highly desirable and essential to good practice that the specifications be reasonably definite and complete, and the chem- ical or physical qualities or test requirements be so completely speci- fied as to leave no doubt in the minds of either party as to what is re- quired. § 182. Specifications by Name Only. — The simple name of a material is usually quite insufficient as a basis for a bid or contract un- less it be accompanied by a previous inspection by a party conversant with the needs to which it is to be applied. No material is so pure, unadulterated or uniform in quality that its name carries with it and assures the possession of the necessary qualifications for the purpose for which it is to be used. Every ma- terial has more or less impurities besides the basic material signified by its name, and no alloy is sufficiently described, as to constituents, by the commercial name ordinarily applied to it. Iron and steel range widely in characteristics in accordance with the variation in the con- stitutional elements and the processes used in their production, and certain limitations and requirements must be specified whenever the most common and ordinary forms of these materials are not sufficient for the purposes to which they are to be applied. Brasses, bronzes and other alloys vary widely in their composition and consequent char- acter, and while practice frequently places a certain limit or range to the composition designated by a certain name, it will seldom if ever so closely define that composition as to render unnecessary a detailed specification. The important work of the Pennsylvania Railway testing labora- tory at Altoona is devoted largely to specifications for materials, and the amount of labor involved and time necessary for their adequate preparation are very great. Almost the entire activities of the Ameri- can Society for Testing ^Materials are devoted to the questions of specifications for materials. The uncertainties resulting from inadequate specifications are well illustrated by a case recently tried in an Eastern court. A com- pany placed an order with a steel foundry company as follows : "Six tray lips, pattern A — 1044. These lips are to be of vanadium cast steel 0.35 to 0.45 carbon annealed. Care should be taken that the metal in the cutting edges is solid and of the best quality." specifications by Name 309 These castings when received and upon use were very unsatisfac- tory. Some broke within a few hours and all broke within a com- paratively short time under less service than some of the ordinary open hearth tray lips previously used. Payment for the lips was refused, and suit entered during the testimony developed as follows :^ "The superintendent of the steel foundry testified that 63/2 lbs. vanadium (alloy about one-third pure) was placed in each pot of 1,600 lbs. steel, which would amount to from 0.15 per cent to 0.16 per cent (calculation shows 0.1354 per cent) ; that vanadium put into castings varies from 0.05 per cent to 0.15 per cent, sometimes higher if it is ordered higher; also that the amount of ferrovanadium lost in the melt varies a good deal with the temperature of the steel, from noth- ing up to one-half of one per cent. A chemist stated that he found the vanadium content of the castings to be 0.03 per cent and 0.04 per cent ; carbon content, 0.375 P^^ ^^^^ ^^^ 0.384 per cent. A metallur- gist stated that the addition of 6^ lbs. of ferrovanadium (33% per cent vanadium) to 1,600 lbs. of steel would be equivalent in round numbers to 0.14 per cent vanadium, and that there would be at least 20 per cent, and possibly 30 per cent, of that lost. The result would be about o.io per cent vanadium remaining in the steel. iHe stated further that there is a recognized 'standard vanadium steel' not less than 0.15 per cent of vanadium, and that castings containing only 0.03 per cent and 0.04 per cent would not be castings of 'standard vanadium steel,' and that the two castings in question showed numer- ous gas cavities and blowholes. Three other witnesses testified that after the castings were broken they observed numerous holes. "Notwithstanding the foregoing testimony as to the vanadium content and defects of the castings, a decision was given for the plaintiff." It is evident from the above, and from numerous other instances, that might be cited, that a simple name is rarely a sufficient specifica- tion for any fundamental element, be it material or process ; and it is therefore necessary to prepare a specification in which the limiting qualifications shall be given which will assure a material or process fully satisfactory for uses and purposes for which it is to be used. § 183. Unsatisfactory Detailed Specifications. — The difficulties of preparing specifications in detail for any material is illustrated by the recent serious trouble with "brass" and "bronze" in connection with the work on the Catskill aqueduct. Iron and steel when exposed to moisture rapidly corrode and working parts are soon destroyed or ' Eng. News, Vol. 74, pp. 946-7. 310 Specifications for Materials rendered useless. To overcome this difficulty manufacturers of ap- paratus and material which are exposed to such conditions, and the en- gineers who use such apparatus and materials, have long sought an in- corrodible material of moderate price and of sufficient strength to with- stand these conditions. In general, alloys of copper with zinc, tin, nickle, aluminum, etc., in many combinations have been used for such purposes to a greater or less extent for many years. There has probably been no single piece of engineering construc- tion on which such large quantities of such materials have been used as in the Catskill aqueduct where the total has amounted to nearly three million pounds. This consisted of castings and forgings, the former ranging from small pieces to pieces of 22,000 pounds, while the forg- ings ranged from small bolts, to stems for valves and sluice gates in some cases six inches in diameter and over thirty feet in length. The principal specifications issued by the board of water supply and cover- ing this material, are as follows : BRONZE CASTINGS "All bronze castings shall be made of new metal, shall be free from ob- jectionable imperfections and shall conform accurately to patterns. When the castings are being machined, if the metal shows signs of imperfect mix- ing, they shall be rejected. Unless otherwise called for in the specifications, or upon the drawings, bronze where indicated upon the drawings shall mean "manganese bronze." MANGANESE BRONZE "All manganese bronze shall be equal to Spare's, Parsons' or Hyde's mang- anese bronze, and shall have a tensile strength of not less than 45 per cent. of the ultimate tensile strength and an elongation of not less than 25 per cent. BRASS RIVET ROD "Tensile strength of brass rivet rods shall be not less than 55,000 pounds per square inch. The elastic limit shall be not less than 30,000 pounds per square inch, and the elongation not less than 20 per cent. STEMS "The main gate stem shall be of manganese bronze, or other bronze of approved composition, of such dimensions that when placed in tension under a load in pounds equal to the area of the valve opening in square inches mul- tiplied by 125, the minimum cross-section of the stem shall have a resultant unit stress not exceeding two-thirds the elastic limit of the material used. These stems shall be turned straight and true and shall have all threads lathe- cut. Unsatisfactory Specifications 311 ROLLED BRONZE "Whenever the term "bronze" is used in these specifications in a general way, or on the drawings, without qualifications, it shall mean manganese or vanadium bronze, or monel metal. Whenever the characteristics of any ma- terial are not particularly specified, such material shall be used as is custo- mary in first-class work of the nature for which the material is employed. "The minimum physical properties of bronze shall, except as otherwise specified, be as follows: CASTINGS Ultimate tensile strength 65,000 lb. per sq. ;in. Yield point 32,000 lb. per sq. in. Elongation 25 per cent. ROLLED MATERIAL Ultimate strength 72,000 lb. per sq. in. Yield point 36,000 lb. per sq. in. Elongation 28 per cent. ROLLED MATERIAL, THICKNESS ABOVE ONE INCH Ultimate strength 70,000 lb. per sq. in. Yield point 35,000 lb. per sq. in. Elongation 28 per cent. "After being forged into a bar, rolled or forged bronze shall stand, first hammering hot to a fine point; second, bending cold through an angle of 120 degrees to a radius equal to the thickness of the bar." While some trouble was experienced with bronze pipes the prin- cipal difficulties were due to defects in large plates and in bolts, rods, side bars and ladder rungs. Many of these defects developed prior to installation where the material had been in storage for a considerable time. These defects consisted of cracks, sometimes very fine and only superficial while others were open and penetrated deeply into the ma- terial. In some cases such defects did not develop for two or three years after the material had been received and after the tests had indi- cated that the material was entirely satisfactory. Even the use of hot rolled rods and of thoroughly annealed cold rolled material supposedly free from initial stresses was not universally successful. "The trouble with brass or bronze experienced on the Catskill aqueduct may be classified as follows : "First : Break from stresses — a. Initial stresses due to methods of manufacture of the fab- rication. b. Applied stresses due to use. "Second : Damage by wrong heat treatment as in forging, bending, flanging, upsetting and annealing. * * * 312 Specifications for Materials "Seemingly both makers and users have misinterpreted the results of the usual standard laboratory test from lack of knowledge of char- acteristics of the copper alloys not revealed by tests. * * t? "As these investigations have proceeded, it has become evident that the engineers' present necessity is not merely an explanation of certain failures of brass but a fundamental knowledge of the physical characters and capacities of this group of alloys, knowledge which will be a safe and dependable guide in their manufacture and use."^ The difficulty on the Catskill aqueduct has raised the question not only of proper specifications for the material but of the responsibility of the contractors who have furnished the same. Neither of these questions has been settled at this date. In addition to the specifications above given, the contract further stipulates that : "Inspection of the work shall not relieve the contractor of any of his ob- ligations to fulfill his contract as herein prescribed, and defective work shall be made good and unsuitable materials may be rejected notwithstanding that such work and materials have been previously overlooked by the engineer and accepted or estimated for payment. If the work or any part thereof shall be found defective before the final acceptance of the whole work, the contractor shall forthwith make good such defects in a manner satisfactory to the en- gineer." The specifications also state that : "He shall complete the entire work to the satisfaction of the board and in accordance with the specifications;" also "all the work, labor and material to be done and furnished under this con- tract shall be done and furnished strictly pursuant to and in conformity with the attached specifications and the directions of the engineer." To what extent the contractors should and can be held liable under their contract for defective materials furnished which were carefully inspected, tested and accepted and in which defects were developed so long after their manufacture and acceptance, is a serious and impor- tant question and involves in th's instance a liability for a very large expense which must be sustained either by the city or by the contractor. Difficulties with similar materials have been experienced in connec- tion with the iMinneapolis filter plant, the work on the Panama Canal, , and in the U. S. Navy. It is quite possible that many of the difficulties which have occurred in the use of this material have been due to com- mercial competition rather than to the lack of knowledge and experi- - Brass in Engineering Construction by A. D. Flinn, Deputy Chief Engi- neer, Board of Water Supplies, City of New York. Proceedings of the Mu- nicipal Engineers of the City of New York. Correct Specifications 313 ence among manufacturers, and it is probable that the best manufac- turers shouM be ready at suitable prices to fabricate these materials to meet all reasonable requirements and to give suitable guarantees to this effect. It is doubtful however if such results can be obtained in open competition. § 184. Basis of Correct Specifications. — From the discussion in the two previous sections it is evident that the preparation of specifica- tions suitable to assure proper results is often attended with great diffi- culties and much uncertainty, and that there is no rule universally ap- plicable for their preparation. In the actual preparation of specifica- tions much will depend on the conditions under which they are to be prepared. If the quantities involved are small and the function of the material unimportant, the preparation of an elaborate specification even w^hen possible is hardly desirable as materials of commercial quality will probably be entirely satisfactory and either the risk or cost of re- placement is not large and may readily be taken. As the quantities and importance increase, the necessity of greater care to secure correct specifications also increases, and the question as to how the character of the work or material can be controlled and the desired results secured becomes extremely important. Every material has certain physical and chemical properties among which may be some or all the following : Physical Properties. — Size, shape and dimension. Color, transparency, general appearance and appearance of fracture. Uniformity, homogenity and absence of apparent defects. Specific gravity or relative weight, density and porosity. Properties of physical combination (as alloys, etc.). Physical composition. iHardness and elasticity. Strength (tension, compression, torsion or impact). Physical conditions under manipulation or as a result of man- ufacture of working into form for use. (Finish, defects, flaws, structural stresses, etc.) Calorific Qualities. — iMelting and boiling points. Specific heat. Conductivity. 314 Specifications for Materials Cubical and linear expansion. Heating value (fuels). Electrical Properties. — Specific resistance. Relative conductivity. Chemical Properties. — Atomic weight. Chemical composition. Chemical combination. Chemical impurities. Corrodibility. Some or all of the above properties may in some forms have an important effect on the quality of the material needed for the particular use to which it is to be applied ^ These effects however are not always known or appreciated although certain qualities may be very essential and easily determined, while others are approximately understood and may be correspondingly helpful in the selection. These properties may be determined by inspection which, however, involves judgment and ex- perience and will therefore dift'er in results with the individual, and standard tests which are far more exact when made by men of even limited experience but who are familiar with various physical and chemical manipulations on which such tests are based. The limitations of these qualities by specifications are useful only when the effect of such qualities on the value of the material for any particular case is known, and where such value is unknown other methods of control are necessary. In the preparation of specifications for all materials and all proc- esses, workmanship, manufactured articles, machines or structures, the control of the desired results may be effected in one or more of the fol- lowing ways, which are however more or less directly related, namely : 1. By composition or properties, and manipulation or workmanship. 2. By inspection. 3. By tests. 4. By guarantees. 5. By selecting those successfully used under similar conditions. 6. By requiring the equivalent of a selected standard. § 185. Composition or Properties and Manipulation or Work- manship. — It is frequently the case that a specified composition of known material will give the results desired. For example when ce- ment is furnished a contractor and satisfactory sand and gravel are available, the specifications for concrete need include only its composi- Inspection 315 tion and method of manipulation. No tests are usually admissible for the results of the tests will necessarily be controlled by the composi- tion and manipulation. In the same manner machinery bearings may be controlled by a requirement for certain definite alloys known to be satisfactory for similar service, and a certain specified grade of work- manship. In both cases and shape and dimensions must be fixed by the design. § i86. Inspection. — Where considerable experience is available it has commonly been ascertained that a certain appearance or the pos- session of certain qualities which can be determined by inspection, more or less clearly indicate the suitability of the material for the require- ments of a particular use. Appearance, finish and workmanship must be determined in this way, in any event, although the character of finish and of workmanship can and should be so defined as to indicate whether ordinary or extraordinary requirements are demanded. Uniformity, homogenity and the absence of apparent defects must all be determined by inspection. Various building materials such as lumber, brick, stone, etc., not subject to great stresses, are accepted or rejected on inspection, the inspection defining their general character ; the material of the lumber and the lim'tations of its imperfections in accordance with commercial standards, the general character of the brick and the extent to which defects will be admitted, and the general character and size of the stone. In all such cases the inspector needs previous experience under the direction of others who are familiar with these various materials and their manipulation in practical construction, otherwise he may admit unsatisfactory workmanship and material or impose undue hardships on the contractor. § 187. Tests. — When a detailed knowledge of the elTect of vari- ous qualities is available, the control of work and material by means of recognized standard tests is the most desirable. In such cases the cur- rent knowledge of these qualities and characteristics may be insuf^cient to permit the preparation of specifications which will result in the fur- nishing of satisfactory material, as in the case of the brass in the Cats- kill aqueduct ; but the best knowledge available will either have to l)e used and the risks of the results taken unless a sufficient investigation is made to determine the real qualifications which must be possessed by the material in order to render it satisfactory. Investigations of this kind are inexpedient unless the quantity of material is so large as to warrant the expense involved and the time during which the material 316 Specifications for Materials is to be used is sufficiently long that suitable researches can be made. Such tests are constantly being made in the laboratory of the Pennsyl- vania Railroad Company at Altoona, Pa., and in the laboratories of various large manufacturing companies and of various universities. Usually however extended investigations are inexpedient on most en- gineering works. In general the various qualities required must be susceptible of some method of determination, test or measurement. Certain qualities for example may be determined as follows : Quantity by number, weight or measurement. Strength by tension, compression, torsion or impact tests. Composition by chemical or mechanical analysis. Duty, efficiency, heat value and power consumption by tests. Resistance to conductivity, as in the case of electricity, light, heat, etc., by specified tests. § i88. Guarantees. — It is evident that a material, machine or structure may be properly controlled after its quantity, capacity or di- mensions have been satisfactorily established, by a suitable guarantee from the manufacturer or contractor that he will replace all or any part or portion of the same which may prove defective within a certain definite period or fails to give certain results and without othief definite requirement. Guarantees are not always satisfactory to the purchaser because they do not assure satisfaction where failures do oc- cur, and the delay and expenses of replacement are such that it many cases, that which is not fully satisfactory will be accepted rather than undergo the annoyance, delay and expense of having to remove work which has been done and again replacing it with possibly little better results. Guarantees to be of value must be carefully drawn and must cover all contingencies in such a manner as to protect fully the pur- chaser and yet inflict no undue hardship on the manufacturer or con- tractor. It is evident that guarantees which will cover a long period of use are difficult and expensive to secure and equally difficult to en- force. The manufacturer hesitates to give a guarantee for a consider- able period of time because of the trouble and expense which may be involved and because of the uncertainties as to the actual treatment of his material, apparatus or machine in connection with the work for which it is to be furnished. The cause of failure in a material or ma- chine which has failed after several years' use is often doubtful. Is the failure due to faulty material or to faulty use? The facts are difficult to determine and still more difficult to prove, and the manufac- turer naturally refuses to take the risk unless compensation for the Guarantees 317 same is unduly great from the standpoint of the user. For this reason long time guarantees are as a rule impracticable to secure, although in general such guarantees will be made for a period covering the time of inspection tests and construction as in the Catskill aqueduct case pre- viously cited. Further than that it is usually inexpedient to go and the user must either take the risk or pay an excessive price. § 189. Successful Use. — In many cases materials, machinery, etc., may be selected on the basis of satisfactory results of actual ex- perience under similar conditions of use. In such cases competition may be secured by including the products of several different manufac- turers who are known to furnish satisfactory goods. In such cases the letting cannot be left open to general competition on the basis of mini- mum price, as new or unknown goods may be proposed concerning which no adequate information is available. No better method for the selection of many articles is available than that based on long and suc- cessful use under a considerable range of conditions. It is important, however, to determine that the conditions of use are comparative and that the present quality of the material or article as now offered is fully equal to that on which the experience is available. § 190. By Comparison with a Standard. — Materials, supplies and manufactured articles and the results of fundamental construction may also be controlled by comparison with standards more or less defi- nite and which must consist of similar articles known to be satisfactory. The comparison with such standards must be gaged by tests or inspec- tion. Take for example the hardware fittings, locks, hinges, etc., for the doors of a large and important building. These will seldom be made to design but will usually be selected from the manufacturer's catalog. They may vary from the simple work done by local black- smith to the artistic bronze production of the highest grade. Under the conditions of the work only certain limitations are possible. Hinges may be required of certain material and of certain dimensions ; to some extent, finish may be prescribed. Even these must be kept within the limits of designs actually available in order to keep the ex- pense within limits. The design, unless special and this is seldom prac- ticable, must be selected from the catalogs of manufacturers and can be specified only as a certain design of a certain company, or the equal thereof. This method is evidently unsatisfactory as it gives a great ad- vantage to a single manufacturer whose goods are thus directly stated to be satisfactory, and therefore when this method must be used, as it must frequently with goods similar to the hardware named above, two 318 Specifications for Materials or more comparative standards from different manufacturers should be named, if practicable. In general when the preparation of specifications for special or proprietary articles is contemplated, it is frequently desirable to corre- spond directly with several leading manufacturers and ascertain what specifications they will meet and what guarantees they will agree to fur- nish. Without such correspondence, the preparation of specifications with certain definite requirements and certain fixed guarantees satisfac- tory to the purchaser, is apt to give barren results through the refusal of the manufacturer to bid under the conditions named. A contract is the meeting of the minds of the two parties involved, and frequently bids can be obtained only by consultation with all parties interested. § igi. Investigation of Materials. — In preparing specifications for materials or other fundamental elements of construction, the engi- neer is cautioned against the unintelligent copying of similar specifica- tions prepared by others for possibly quite different conditions. The engineer is advised when preparing such specifications to in- vestigate thoroughly and in detail the materials or other elements which are to be used, before specifications for the same are prepared. The investigation should include such of the following factors as may be pertinent : 1. Occurrence. 2. Properties. 3. Use or application. 4. Processes of manufacture. 5. Manufacturers, dealers, etc. 6. Methods of use. 7. Current prices. 8. Reference to sources of information. (See "Notes on Aluminum" sec. 193.) The engineer should also consider and determine what properties should be limited, and the commercial limitations which should be speci- fied. The limitations imposed should not exceed practicable Hmits, and should be only those reasonably desirable or actually essential for the purpose in view. Such information is often contained in the discus- sion of technical societies, in technical journals, in reference books and special treatises, and in specifications prepared for similar purposes. On unfamiliar subjects, such limitations should usually be determined from more than a single source, Investigation of Materials 3lQ Not all of the qualities or characteristics of a material are to be described in the specifications but only such as may so vary in the commercial product as to render the material unsuited for the pur- pose for which it is to be used. A knowledge of such limitation is not common to engineers but is usually possessed only by those who are familiar with the material in a practical way. The qualities of materials that have been generally adopted for important purposes, have commonly been determined by numerous tests and investigations which have been frequently described and discussed before the technical societies. In such cases the engineer, although unfamiliar with the use of such materials, can by study and investigation ascertain the limiting qualifications which should be embodied in a proper specification. In other cases, a material may have a more or less local character or may be in the process of change, and the desirable or practical limiting characteristics may be more difficult to determine and spe- cify. An investigation of the material, inquiring of those parties familiar with its production and use, will usually give the required information. It is in general undesirable and impracticable uniformly to re- quire the best of every material, for such specifications will involve great -and unnecessary expense. The material should have the quali- ties needed for the place and under the circumstances in which it is to be used, no greater or no less. A greater requirement involves useless expense ; a less requirement involves improper materials. After the investigation is completed, an outline should be prepared of the special requirements necessary for the specific uses for which the material or element is needed (see Sections 194 and 199), after which the specifications can then be prepared. In the preparation of such specifications, it is equally important : First: To include all requirements of quality or workmanship needed to secure the results desired, and Second: To omit any unnecessary requirements or restrictions, either of quality or workmanship, in order to avoid unnecessary ex- pense. The system, if carefully carried out, will result in the thoughtful consideration and preparation of specifications, which is essential for the best results, and will eliminate the thoughtless copying of errone- ous specifications. When a set of specifications has once been pre- pared in this way, the notes should be retained for future reference and can occasionally be brought up to date. It will not be necessary to 320 Specifications for Materials repeat this process with each rewriting of similar specifications ; and after wide experience with certain materials or elements, even refer- ence to the notes may become unnecessary. The same system can, however, be used to advantage whenever the practicing engineer is called upon to prepare specifications for material or elements of con- struction, concerning which his experience is limited. § 192. Conclusions of Dr. Dudley. — Dr. Chas. B. Dudley, in his Presidential address to the American Society for Testing Materials, at its annual meeting in 1903, summarizes his conclusions in regard to the making of specifications for materials as follows : 1. "A specification for material should contain the fewest possible re- strictions, consistent with obtaining the material desired. 2. "The service which the material is to perform, in connection with reasonably feasible possibilities in its manufacture, should determine the limitations of a specification. 3. "All parties whose interests are affected by a specification should have a voice in its preparation. 4. "The one who finally puts the wording of the specification into shape, should avoid making it a place to show how much he knows, as well as a mental attitude of favor or antagonism to any of the parties affected by it. 5. "Excessively severe limitations in a specification are suicidal. They lead to constant demands for concessions, which must be made if the work is to be kept going, or to more or less successful efforts of evasion. Better a few moderate requirements rigidly enforced, than a mass of excessive limitations, which are difficult of enforcement, and which lead to constant friction and sometimes to deception. 6. "There is no real reason why a specification should not contain limitations derived from any source of knowledge. If the limitations shown by physical test are sufficient to define the necessary qualities of the ma- terial, and this test is simplest and most easily made, the specifications may reasonably be confined to this. If a chemical analysis or a microscopic ex- amination, or a statement of the method of manufacture, or information from all four, or even other sources, are found useful or valuable in defining limitations, or in deciding upon the quality of material furnished, there is no legitimate reason why such information should not appear in the specifi- cations. Neither the producer nor the consumer has a right to arrogate to himself the exclusive right to use information from any source. 7. "Proprietary articles and commercial products made by processes under the control of the manufacturer cannot, from the nature of the case, be made the subject of specifications. The very idea of a specification in- volves the existence of a mass of common knowledge in regard to any ma- terial, which knowledge is more or less available to both producer and con- sumer. If the manufacturer or producer has opportunities, which are not available to the consumer, of knowing how the variation of certain constitu ents in his product will affect that product during manufacture, so als6 does the consumer, if he is philosophic and is a student, have opportunities not available to the producer, of knowing how the same variation of con- Conclusions of Dr. Dudley 321 stituents in the product will affect that product in service, and it is only by the two working together, and combining the special knowledge which each has, that a really valuable specification can be made. 8. "A complete workable specification should contain the information needed by all those who must necessarily use it, in obtaining the material desired. On railroads this may involve the purchasing agent, the manu- facturer, the inspector, the engineer of tests, the chemist, and those who use the material. A general specification may be limited to describing the prop- erties of the material, the method of sampling, the amount covered by one sample, and such descriptions of the tests as will prevent doubt or ambiguity. 9. "Where methods of testing or analysis or inspection are well known and understood it is sufficient if the specification simply refers to them. Where new or unusual tests are required, or where different well-known methods give different results, it is essential to embody in the specification, sufficient description to prevent doubt or ambiguity. 10. "The sample for test representing a shipment of material should always be taken at random by a representative of the consumer. 11. "The amount of material represented by one sample can best be de- cided by the nature of the material, its importance, and its probable uni- formity, as affected by its method of manufacture. No universal rule can be given. 12. "The purchaser has a right to assume that every bit of the material making up a shipment, meets the requirements of the specification, since that is what he contracted for and expects to pay for. It should make very little difference, therefore, what part of the shipment the sample comes from, or how it is taken. Average samples made up of a number of sub- samples, are only excusable when the limits of the specification are so nar- row that they do not cover the ordinary irregularities of good practice in manufacture. 13. "Retests of material that has once failed should only be asked for under extraordinary conditions, and should be granted even more rarely than they are asked for, errors in the tests of course excepted. 14. "Simple fairness requires that when it is desired that material once fairly rejected should nevertheless be used, some concession in price should be made. 15. "Where commercial transactions are between honorable people, there is no real necessity for marking rejected material, to prevent its being of- fered a second time. If it has failed once, it will probably fail a second time, and if return freight is rigidly collected on returned shipments the risk of loss is greater than most shippers will care to incur. Moreover, it is so easy for the consumer to put an inconspicuous private mark on rejected material, that it is believed few will care to incur the probable loss of busi ness that will result from the detection of an effort to dispose of a rejected shipment by offering it a second time. 16. "All specifications in actual practical daily use need revision from time to time, as new information is obtained, due to progress in knowledge, changes in methods of manufacture, and changes in the use of materials. jA new specification, that is one for a material which has hitherto been 322 Specifications for Materials and Supplies bought on the reputation of the maimers and without any examination as to quality, will be fortunate if it does not require revision in from six to ten months, after it is first issued. 17. "In the enforcement of specifications, it is undoubtedly a breach of contract legitimately leading to a rejection, if the specified tests give results not wholly within the limits, and this is especially true if the limits are rea- sonably wide. But it must be remembered that no tests give the absolute truth, and where the results are near, but just outside the limit, the material may actually be all right. It seems to us better, therefore, to allow a small margin from the actual published limit, equal to the probable limit of error in the method of testing employed, and allow for this margin in the original limits, when the specifications are drawn. 18. "Many producers object to specifications on the ground that they are annoying and harassing, and really serve no good purpose. It is to be feared that the complaint is just, in the cases of many unwisely drawn specifications. But it should be remembered that a good reasonable specifi- cation, carefully worked out, as the result of the combined effort of both producer and consumer, and which is rigidly enforced, is the best possible protection which the honest manufacturer can have against unfair competi- tion. 19. "Many consumers fear the effect of specifications on prices. Experi- ence seems to indicate that after a specification has passed what may be called the experimental stage, and is working smoothly, prices show a strong tend- ency to drop below figures prevailing before the specifications were issued. 20. "A complete workable specification for material represents a very high order of work. It should combine within itself the harmonized antago- nistic interests of both the producer and the consumer, it should have the fewest possible requirements consistent with securing satisfactory material should be so comprehensive as to leave no chance for ambiguity or doubt, and above all should embody within itself the results of the latest and best studies of the properties of the material which it covers." § 193.

Notes on Properties — Aluminum is a white malleable metal of low specific gravity. On ac- count of its softness, it is for many purposes alloyed with iron, copper, tin or zinc. Its common impurities are silicon and iron. Under ordi- nary conditions aluminum may be considered as quite non-corrodible. It is affected, however, in the oxides of some atmospheres, namely, near salt water or where the air contains oxides of sulphur. Hydro- chloric acid is the best solvent, and strong solutions of caustic alka- lies readily dissolve it. Uses — Aluminum has large application for electrical conductors where insu- lated conductors are unnecessary. The increase in cost of insulating the larger aluminum wire, together with the difficulty in making sol- dered connections, has prevented its wide use as insulated conductors. Owing to the greater coefficient of expansion over that of copper, the sag allowed in stringing aluminum wire must be greater than that used in copper wire lines. It is common to make aluminum transmis- sion lines of cable formed of aluminum wires, around a core of high elastic limit steel, in order to do away with the excessive sag. in making castings under ordinary conditions, a shrinkage of 3/16 inch per foot should be allowed. ^Aluminum is very "hot short" just before solidifying in the mould. Alloys — Aluminum can be hardened and strengthened by a small quan- tity of copper. About 3% of copper doubles the tensile strength and increases the specific gravity from 2.67 to 2.85. Rolled bronze bars made up of 907r copper and lO^/c aluminum have tensile strength of I00,000# per square inch, elastic limit of 60,000# per square inch and elongation of 10%. Thermit Process of Welding — This process depends upon the affinity existing between finely divided aluminum and oxygen. When an intimate mixture of aluminum and iron oxide is ignited, the temperature raises to about 5400°, and whit^ hot fused iron results. The chemical reaction of this process is 2 Al + Fe p., =-. Al p.. 4- 2 Fe. 324 Specifications for Materials and Supplies Aluminum is used in steel manufacture to prevent the retention of gases within the steel, and thus produce a solid ingot. It also increases the fluidity of steel and thus tends to produce sharper castings. Manufactured by The Aluminum Company of America, Pittsburg, Pa.

Assignment on Fundamental Material and Supplies. The student should select one or more of the following subjects, and first : Investigate the subject in considerable detail and prepare a report on the same. (See sec. 193) ; second: Outline the practicable limitations as to the qualities and such other requirements as should be included in a specification for the material for the use to which it is to be applied. (See sec. 194) ; and third: Prepare or select specifications which will form the basis for an intelligent bid and contract for such material. (See sec. 195.) For looking up these various subjects references are given at the end of the Chapter and in the Bibliography at the end of the volume. This list of materials is by no means complete, and other similar sub- jects having a local importance can often be substituted to advantage. So far as possible the use for which a material is suggested to be ap- plied is placed opposite the "kind" of material. In many cases, however, the various kinds of material mentioned can be applied to several or all of the various uses suggested. 326 Specifications for Materials and Supplies It will usually be desirable to specify more definitely the exact use for which the material is desired. In doing this the specification should be given a local significance by making it apply to some local use, the conditions of which can be investigated and considered by the student.

Fundamental Processes. — The fundamental processes of construction work should be investigated in very much the same manner as materials and supplies. The preparation of specifica- tions for these processes if carried into detail is even more difficult than those for materials. In both materials and processes, improve- ments are constantly being made, and the methods employed are constantly undergoing changes and improvements. As a general rule, it is unwise to specify methods in detail, as results are the end desired and the detailed methods to be pursued should be designated only to the extent necessary to secure the results desired. If the methods to be pursued are fully spec"fied, the contractor becomes a ''servant" and not an "independent contractor," and the principals may become liable for casualties which may occur and unsatisfac- tory results which may obtain on account of improper methods of procedure. As a general rule, the contractor should be left reason- ably free to pursue those methods which his experience dictates, for it is largely on account of this experience that his services are secured. He should, however, be required to do those things or use those processes which are clearly known to be essential to secure proper results. Ordinarily the specifications for an engineering proc- ess should include : I. A general description of the work to be done. II. Reference to plans, profiles, etc., provided. III. The material to be used. (^Materials covered by another specification.) IV. The operations included. V. Precautions to be taken. VI. The results to be obtained. § 198. Earthwork and Rock Work. — Among the processes most common in engineering works is the excavation or construction of earth and rock works. Such works have many features in com- mon, while other features may be special and peculiar to a particu- lar work. For the purpose of the general study of specifications, all such works can be analyzed together. In using the analysis for the preparation of specifications, all specifications not applicable to the Earthwork and Rockwork 331 case in hand should, of course, be omitted. In the same way it must be remembered that besides the headings given in the analy- sis, there are various other items in regard to the general character of the work, contingencies, delays, the hazards of construction, the furnishing of tools, plant, etc., which are usually included in the general form of agreement, but which may be included in the spec- ification, if desired. In addition to these there may be special fea- tures which demand special treatment. While an attempt has been made to make the analytical form given as complete as practicable, it is offered simply as a basis or a general model for a special form to be prepared by the engineer for any special work he may have on hand. § 199.

General Description. — Under this title are included vari- ous data descriptive of work which may be subdivided into (A) De- scription, (B) Location, (C) Dimensions, (D) Form, (E) Grade, and (F) Division of work. Where the earth work is a part of other work, the location is usually sufficiently well described in the general description of the entire work ; otherwise a special description may be desirable. In minor works the description may include, in a single para- graph, all necessary facts in regard to location, dimension, form, grade, and divisions of work, while in important work each of these factors may require special treatment. The following examples show the common practice in writing of such specifications : § 201. (A) Description, and (B) Location. a. For Channel or Ditch. — "A channel having side slopes of two feet hori- zontal to one foot vertical, and a width of twelve feet at the bottom, shall be constructed on the grade shown on the profile from the outlet of Williams Pond to the Bear River on the general line shown on the map." h. Trenches for Pipe Sewers. — "All sewers shall be located on the lines shown on the map. The trenches shall be excavated to a depth sufficient to place the flow line of the pipe on the grade shown on the profile, and of such a width that they shall be, at the center of the sewer, one foot wider than the greatest horizontal diameter of the pipe to be laid therein. The bottom of the trench shall be excavated as nearly as practicable to the form and size of the lower half of said pipe. Suitable excavations shall be made to fit all junctions or other specials wherever needed." c. Trench for Water Pipe. — "1. Line and Grade: The trenches for the pipe shall be opened in accordance with the lines and grades given by the engineer. The pipe lines shall be laid uniformly twenty-two (22) feet from the northerly sides of the various streets and avenues. The right, however, to depart from this general rule is reserved by the first party." "2 Size of Trench: Said trenches shall be one foot wider than the greatest exterior diameter of the pipe to be laid therein." Earthwork and Rockwork 333 c. Bell Holes: At all points the trench shall be widened and deepened sufficiently to admit of free access for calking all around said pipe, and so that the bell of the pipe shall have no bearing on the bottom of the trenches. Such enlargement of the trench shall be made before the pipe is lowered into it." d. Excavation for Bridge Substructures: "The excavation for all piers or abutments shall be to such a depth as shall permit the bottom of the grillage, if grillage be used, or the bottom of the masonry footings, if no grillage be used, to be placed at an elevation about ninety (90) feet above city datum (to which reference plane all elevations on the drawings and in specifications for this work are referred). The engineer shall determine the exact elevation of the foundation of each structure. The excavation shall be of the size and dimensions directed by the engineer." e. Excavation for Masonry Foundations: "The excavation will be of the form, dimensions and depth shown on the drawings, or to such addi- tional depth as the nature of the material may require." /. Street Grading: "All streets and avenues on which pavements are to be laid, including roadway, parking sidewalk intersection and all street and alley approaches shall be graded to the lines and cross sections shown on the profiles and sections of the same." g. Railroad Grading: "Under this head shall be included all excavations and embankments for the construction of the roadbed for both main and side tracks, for all station grounds and switch yards, and including also the excavations for all drains and ditches in connection with the road, and the excavations for the foundations of all bridges, culverts, cattle guards, and all earth work necessary for the change and reconstruction of public or private roads and crossings, or for the changing of water-courses and for all other earthworks incident to the construction of said railroad." h. Chicago Drainage Canal: ''Location: "The work covered by and in- cluded in these specifications in the excavation of that part of the main drain- age channel, and the building of certain collateral works for the sanitary district of Chicago located between the Willow Springs Road in Section 32 of Township 38 North, Range 12 East of the Third Principal Meridian, in Cook County, Illinois, and the middle of Section 14, near Lockport in Town- ship 36 North, Range 10 East of the Third Principal Meridian, in Will County, Illinois, beginning below but near the said Willow Springs road, the said part of the said main drainage channel follows the Desplaines river valley, being located north and west of the Illinois and Michigan canal, approximately as shown on the accompanying plans, marked "2 a," and as shall be located by the engineer, and described as follows: " 'The line of said channel shall begin at Willow Springs road and shall continue in a direction parallel to and 460 feet from the river bank of the canal above Willow Springs, joining by an easy curve a line parallel to and 460 feet from the canal bank in the straight reach above Sag, thence by an easy curve in a straight course to the county line and parallel to and 730 feet from the bank of the canal in the straight reach at and above Lemont; thence by an easy and continuous curve to a straight course parallel to and 334 • Specifications for Processes 460 feet from the canal banl?; in the straight reach at and below Romeo, said course terminating at or near the middle of Section 14, of Lockport Town- ship; the course opposite Lemont to be subject to a change of 200 feet if found desirable, said course throughout being so located as to facilitate the spoiling of the waste material from the channel on either side. The total approximate length is 74,000 feet or 14 miles'" (San. Dist. of Chicago.) i. Emhankment: "The embankments shall be 30 feet in width at the top, and shall have a slope of two (2) feet horizontal to one (1) vertical, or such other slope and such cross section as the engineer may determine for any particular case," j. Em'banTcment'. "In embankment, the sides shall be neatly and uni- formly dressed to a slope of two and one-half (2 1-2) horizontal to one (1) vertical, or such other slope as the • engineer may direct in any particular case." § 202. (C) Dimensions, (D) Form, and (E) Grade. a. Dimensions of^ Cross Sections: "The bottom of the finished channel shall have a width of 160 feet in the clear; where the channel is in rock, the sides of said channel shall be kept vertical, except as to necessary offsets occasioned by the use of the dredging machine. "The sides of the rock channel are to be worked out with a channeling machine from top to bottom, the channels being cut ahead of the blasting. In doing this the bottom of each cut of the machine is to be made to a uni- form level above the grade, and each succeeding one offset six inches from the one just preceding. The contractor will be allowed to work the rock in one or more stopes, at his option, so far as concerns the main portion of the width of the channel, but in case he elects to work the face in stopes having a greater height than the reach of the channeling machine in depth, then the blast holes are to be so disposed as to effectually prevent any blast from breaking or shattering the rock beyond the sides of the prism of the channel, which are to be left as smooth and solid as can be obtained with a skillful and proper use of a channeling machine. "In determining the width of the channel at the top of the rock, the necessary offsets made by the operation of the machine are to be allowed for. Provided, that where the depth of the rock does not exceed sixteen feet there shall be but one reach or cut of the channeling machine made, and that when its depth is over sixteen feet, and not greater than twenty-four feet, there shall be two cuts made; and that nowhere is there to be more than three cuts made for the whole depth of the rock excavation. Where the channel is partly in earth and partly in rock, the earth shall be so excavated as to leave a berm on top of the rock equal to three- eighths (3-8) of the depth of the rock surface below a level 5 feet above datum; provided that the berm shall be in no event less than 5 feet; and provided, further, that where the section in entirely in earth the additional width at bottom shall conform to the above rule; and provided also, that at the level of 5 feet above datum the berm shall not be less than 10 feet, with a slope toward the channel of one-half foot. In all cases the earth shall be taken out with the least slope which is to be found can be safely maintained Earthwork and Rockwork 335 until the retaining walls are built, and as may be directed by the engineer from time to time." (Spec. San. Dist. of Chicago.) &. Grade: "The grade line of the bottom of said main channel at the station designated 740 shall be at an elevation of 24 feet below datum established by the Illinois and Michigan canal trustees in 1847, and shall slope thence uniformly at the rate of 0.08 of a foot vertical to 1,000 feet horizontal to the end of the standard excavation at station 1480, where it shall have an elevation of 29.92 feet below datum. "The sanitary district reserves the right to change said grade by raising or lowering it, or by increasing or decreasing the slope, thereby increasing or decreasing the amount of excavation; provided, that said change shall in nowise affect the terms of this contract as to price, or entitle the said con- tractor to any compensation additional to the rate fixed by this contract, or render the sanitary district liable for any damages, whatsoever, direct or indirect. Provided, further, that the said change shall in no place affect the grade by an amount exceeding four feet; and that the sanitary district shall notify the said contractor of any such change before any portion of said channel shall have been finished in conformity to the grade as hereinbefore specified." (Spec. San. Dist. of Chicago). § 203. (F) Divisions. — In contract work of large magnitude, it is frequently desirable for purposes of letting the work, to divide it into a larger or smaller number of divisions, reserving the right to let the contracts for such divisions to one or more contractors as the party letting the work may elect. a. "Sections for the purpose of eventually designating different portions of the v/ork and of dividing it into contracts, the said part of the main drainage channels shall be divided into 14 sections as follows: "Section 1, extending from the station designated 740 to the station designated 800, "Section 2, extending from the station designated 800 to the station designated 850. "Section 3, extending from the station designated 850 to the station designated 900, etc., etc. "Section 1, 2, 7, 8, 9 and 10 involves certain changes in the river chan- nel opposite. Section 9 involves a possible re-location of the Illinois and Michigan canal, and Sections 8 to 14 inclusive may require railway changes. The sanitary district reserves the right to make all river, canal and railway changes independent of the main work." (Spec. San. Dist. of Chi- cago.) § 204. Materials. — Specifications for materials should include a description of : A. Their (jcncral character and the available information cou'-xm- ing the same. 33d Specifications for Processes B. Their classification, or the kinds of material to be moved, with exact definitions of the character of each class, for which a different price may or will be paid. C. The qualify of material, which may be used in different parts of the w^ork or for different purposes (as for fills, backing filling, etc.) . D. The quantities, including exact or approximate estimates of the amount of the material or of different materials to be moved. E. The method of nicasurenicnts, or the basis on which estimates will be made and the work paid for. F. The shrinkage or increase in volume which will be involved in the handling of the material, to the extent that such change in vol- ume influences the construction or cost of the work. G. Extra excavation, or the material that will be paid for at an extra price either in excess of the common price or aside from a fixed sum that may be made for the major part of the work. H. Extra material and borron' pits, or the sources apart from the location of the work at which material can or must be secured. ]\Iuch care is necessary in designating the meaning of words used in the description of materials, especially when any classification is allowed or when any expense is involved by their occurrence. As pointed out in section 122, of chapter XI. the lowest proposals from intelligent contractors can be secured only by removing so far as practicable all doubts in regard to the nature of the work to be done and the consequent expense to be incurred. Various earth and rock materials to be excavated resist the work of removal in a manner varying greatly with their character and physical condition. Materials like clear sand and mud oft'er little resist- ance, while other materials like rock, cement, gravel and indurated deposits of all kinds offer strong resistance. § 205. (A) General Character. — The nomenclature used to des- ignate these materials has not been standardized and varies greatly with diff'erent engineers. Prelini ^ subdivides these deposits into "very loose soils," 'Moose soils," "friable soils," "soft rock," "ordinary rock," and "hard rock." Gillette - classifies earth excavation into ( i ) "easy earth." in which he includes loam, sand and ord'nary gravel ; (2) "average earth," in- cluding sands and gravels impregnated with clay or loam where a pick 1 See "Earth and Rock Excavations," p. 42. -See "Handbook of Cost Data," second edition, p. 120. Character of Materials 337 or plow drawn by two horses is necessary for loosening before shovel- ing, and (3) "tough earth," in which he includes compact clays, the hard crusts of old roads and all earths so hard that one team of horses can pull and plow only with great difficulty but which two teams of horses can loosen with comparative ease. He adds, "this third class of earth passes by insensible degrees into what is called 'hard pan,' " which he defines as including very compact clay or a mixture of gravel or bould- ers with clay, and "sometimes soft shales that can be plowed with a rooter plow." Certain cemented gravels are sometimes called hard- pan. The earth and soils have also local names, for example "adobe," a term used in the southwestern portion of the United States to de- note any clay of which sun dried brick or "adobes" can be made. "Gumbo" is used in the Mississippi valley to denote a black loam mixed with clay, exceedingly sticky when wet, and often very hard and tough when dry. "Marl" is technically a mixture of clay and lime, but is often employed to designate clay soils with only a small amount of lime, and sometimes disintegrating materials with a soapy texture. The term "quicksand" is usually applied to any sand or sandy material which flows readily when saturated with water. Earthy materials are sometimes classified and described as follows : 1. "Loose earth" which may include those earths having little co- hesion and offering little or no resistance to separation from the re- mainder of the deposit. 2. "Common earth," which may include those having some cohe- sion and may require the use of a spade for removal. 3. "Tough earth," w^hich may require before removal the use of the pick to break it up. These include stiff clay, disintegrating rock and slightly cemented sands and gravel. Rock materials may also be divided into three classes, on the basis of the resistance offered to removal, namely: 4. "Soft rock," which is easily removed by bars and wedges, such as loosely laminated slates and sand stones. 5. "Ordinary rock," which can be removed by bars and sledges, such as sand stones, etc. 6. "Hard rock," which must be blasted. The soft and ordinary rocks may often be more profitably moved by the use of explosives. Very often the term "loose rock" is used for rock which is un- cemented and is loosened from its bed and can readily be moved. The 338 Specifications for Processes term is usually confined by definition to pieces of a limited size, often not exceeding three cubic feet in contents. The term "bedrock" refers to rock in the natural bed, and it may possess various degrees of hardness. Occasionally deposits are described by their geological names, al- though such description gives little information concerning their exact character, as the same geological deposits will vary widely in texture and condition at various places. Examples: a. Excavation and Bridge Al)utm,ents: "The material excavated will be earth, sand, gravel and fragmentary material of various kinds and shall be estimated by the actual cubic contents of the excavation as laid out by the engineer, and shall be paid for at the price per cubic yard bid for such ex- cavation. The material shall be refilled around the completed abutments, and shall be replaced in layers and thoroughly tamped and any surplus ma- terial shall be removed by the contractor and wasted by him at such place or places as the engineer may direct, not more than five hundred feet from the excavator, the cost of all of which shall be included in the price bid for ex- cavation." b. Borings and Soundings: "The location of borings and soundings made along or near line of the aqueduct is shown on Sheet No. 1, which also shows what is regarded as the probable location of the surface of the ledge rock, but it is well known that the surface of any ledge may differ greatly from the location as shown, and that the character of the material encountered can- not be definitely determined by wash drill borings. There is, therefore, no expressed or implied agreement that the line of the surface of the ledge rock or the character of the material encountered by boring, as indicated upon the plan, is given approximately correct." (Met. Water & Sewerage Board.) c. Character of Material — ''General Character of Borings and Soundings: The character of the material through and in which the tunnel is to be con- structed, is indicated on the profile, and sample of material taken from the borings made on the line of the work at the points shown on the drawings may be seen at the office of the City Engineer. These borings are believed to be practically correct, and to represent a fair sample of the material. It is expressly understood, however, that the city does not guarantee the ac- curacy of these borings, and should the conditions be found to differ from those indicated by said borings, the Contractor shall have, for this reason, no claim against said city." d. Wells — Nature of excavation: From the drillings of the first artesian well, it is believed that the strata which lie below the surface, and which may be encountered in sinking the shaft, will be approximately as follows: "Drift (clay, sand, gravel), G7 feet in thickness. "Coal measure shales, 5 feet in thickness, "Burlington limestone, 96 feet in thickness. "Kinderhook group, 261 feet in thickness. "The general thickness and character of the strata as above given, are believed to be approximately correct. These conditions are, however, liable to variation, which variation and the resulting conditions shall be at the Character of Materials 339 risk of the contractor, and said contractor shall not be entitled to any claims for extra compensation for any variation in said strata or in the conditions thereof from those above mentioned, or for additional labor, material, or appliances which he is obliged to furnish by reason of such variation, or for any unforeseen difficulties encountered in the prosecution of this con- tract." e. '[I ells — ''Approximate description of strata: It is expected that the strata which will be encountered in sinking this well will be similar in its nature to the stratification of the first artesian well drilled at Monmouth, which stratification was, approximately, as follows: — Drift 67 ft. Coal measure, shale 5 ft. Burlington limestone 9G ft. Kinderhook group 261 ft. Hamilton and corniferous 88 ft. Guelph and Niagara 68 ft. Cincinnati shales 83 ft. Galena limestone 290 ft. Trenton limestone 116 ft. Saint Peter sandstone 156 ft. Depth of first well 1,230 ft. "Below the St. Peter sandstone there is unknown thickness of the Lower Magnesian limestone, perhaps 300 to 500 feet in thickness, below which the potsdam sandstone deposits occur. "The general thickness and character of the strata as above given are believed to be approximately correct. They are, however, liable to varia- tion, which variation shall be at the risk of the contractor, and said con- tractor shall not be entitled to any claim for extra compensation for any variation in said strata from the above, or for any additional labor, material or appliances which he is obliged to furnish by reason of such variation, or from any unforeseen difficulty encountered in the prosecution of the con- tract." § 2o6. (B) Classification. — Classification is an attempt to sub- divide earth and rock work into classes or kinds of material, which will from their nature require different methods of treatment, and conse- quently different expense in moving them. Where such differences ex- ist it is usually desirable to ask for separate proposals for each class of material. Classification and the opportunity of securing a proper com- pensation for each kind of material which will or may be encountered, obviates the hazard of variation in the amounts of the different kinds of material and guarantees that the contractor will receive payments on each kind in proportion to the amount that obta'ns. The difficulty that arises in carrying out classification lies in the difficulty of explicit definition of class and the difficulty of determining accurately whether a given material lies within one class or another. This determination 340 Specifications for Processes has led to many disputes and much htigation. Many classifications for such material have been used. These sometimes include : a. Earth and rock. b. Earth, loose rock, and solid rock. c. Earth, hardpan, loose rock, and solid rock. d. Loose earth, common earth, tough earth, hardpan, loose rock and solid rock. c. Solid rock, sandstone, cement, shale and earth. Frequently the materials embraced under such classifications grade almost imperceptibly one into another, and in adjusting the limits be- tween earth and hardpan, hardpan and rock, considerable difficulties frequently arise. Warren D. Smith, Professor of Geology at the University of Oregon siubmitted to Economic. Geology for March — April,) 1919, suggestions for a new classification of materials to be excavated. Professor Smith says : ''The following classification has four main group>, and is as follows : NAME All granite rocks, granites, diorites, etc. Sandstones (siliceous cement) Quartzites and quartz masses Traps (basalt) porphyries and volcanic glasses Conglomerates and agglomerates Gneisses, Breccias GROUP I Solid and unweathered rocks All rocks of Group I badly weathered Sandstones (lime or iron cement) Limestones and marbles Serpentines, schists, slates and argillites Hardpan (glacial, etc.) Shales Rubble limestone Loose sandstone Coquina Marls Travertine Tuff Glacial till Silt Mud Sand Gravel Volcanic ash (loose) 1 GROUP II Intermediate rocks GROUP III Soft rocks GROUP IV Unconsolidated (earth) Classification 341 "For use in connection with this classification we think that Pirs- son's 'Rocks and Rock Minerals,' with the tables there included for rock determination, should be used. There is no escaping the fact that the engineer must know the common rocks and minerals. If he does not know them now, he must either take a course where he can learn these, or a geologist must be retained."* As a rule the engineer should be empowered to decide under what class a material encountered shall be included and he will here find opportunity for the exercise of his best judgment. Examples: a. Open trenches — ''Excavation: All excavation will be in sand, gravel, earth, and other drift materials. No rock excavation is expected, but should rock be encountered in the trenches is shall be excavated six inches below the bottom grade of the pipe. All rock requiring blasting to remove will be paid for as rock excavation at $2.00 per cubic yard, and said rock shall be meas- ured eighteen inches wider than the outside diameter of the pipe at the hub end, and from the top of said rock to six inches below the bottom grade of the pipe. All boulders found in the trench requiring to be removed, measur- ing one-half cubic yard or more, will be paid for as rock excavation. In the excavation of rock, all blasts must be properly covered to guard against injury to surrounding objects, and the contractor will be held responsible for all damages to persons or property caused by carelessness or otherwise in the prosecution of this work." b. ''Classification of Material: All material such as earth, clay, sand, gravel, rotten or loose rock, vrhich can be removed with pick and shovel, shall be classed as 'earth excavation.' All rock requiring blasting to remove, shall be classed as 'rock excavation.' " In addition to the above classification, the class Hardpan is some- times also used. \\'hen so used it is usually specified as follows : "Hardpan shall consist of indurated clay, shales or cemented gravel, and which requires blasting for removal." In addition to the above classifications, there are also often included in work, part of which is to be performed under water, the classifica- tion as above indicated, modified by the additional provision "in water," "below water," and "dry" or "above water." "All excavation below low water shall include all necessary extra work caused by the position, and shall be paid for at the price named in the ac- cepted proposition." c. Open Trenches. — "Two prices only are to be paid for materials exca- vated from the open trench and other excavations (except borrow pits), namely, one for the roclt excavation, which is to cover all excavation of solid rock removed by blasting, and all boulders of one-third cubic yard or more in volume; and one for earth excavation, which is to cover the excavation of * Eng. News-Rec. Vol. 82, p. 907. 342 Specifications for Processes all other materials. The price to be paid for borrowed earth is to cover the excavation of all kinds of materials taken from borrow pits." (Met. Water & Sewerage Board.) d. Canals— ''Classification of Material.— AU material excavated under the provisions of this contract is to be classified under one or the other of two heads, viz.: 'glacial drift' and 'solid rock.' "Glacial drift shall comprise the top soil, earth, muck, sand, gravel, clay, hardpan, boulders, framentary rock displaced from its original bed, and any other material that overlies the bed rock. "Solid rock shall comprise all rock found in its original bed, even though it may be so loosened from the adjacent underlying rock that it can be re- moved without blasting." (Spec. San. Dist. of Chicago.) e. Grading — ''Classification: (a) All material handled under the head of 'Grading' shall be classified as follows: 'Solid rock,' 'loose rock,' and 'earth.' "(&) Solid rock shall include all bed rock which cannot be removed without blasting, also all boulders or other masses of rock of not less than one cubic yard which require blasting before removal. "(c) Loose rock shall include all soft shales or other soft or loose rocks which can be removed without blasting, even though blasting may be done to facilitate the work; also all boulders or other manner of rock of not more than one cubic yard, or less then ten cubic feet. "(d) Earth shall include all soil, earth, sand, gravel, loose stone and boulders of less than ten cubic feet contents, and any other material of every description not clearly included under the specifications of solid rock or loose rocks; of all of which the engineer shall be judge." (e) "All materials moved in grading shall be measured in excavation only, and estimated by the cubic yard under the following classes: "Class 1. All material that can be plowed by an average eight-mule team, each animal weighing not less than twelve hundred (1,200) lbs., attached to a suitable ten inch breaking plow, all well handled, by at least four men. Also, all loose material that can, without plowing, be loaded into a scraper by two men. "Class 2. Indurated material of all kinds, which cannot be plowed as in Class 1, but which requires loosening by powder, and can then be removed by scraper. "Class 3. All detached masses of rock, more than two and less than ten cubic feet in volume. And all slate or other rocks, soft or loose enough to be removed without blasting. "Class 4. All rock, not included in the above classes which requires drill- ing and blasting." - In discussing the above specification, the Engineering News re- marks that in a similar specification a dispute arose in regard to the question of whether certain mater'al should be classified as "hard- pan" or "rock," and points out that while certain shales and hard- pan may be loosened in small chunks by a plow, yet true economy of construction would require blasting. Tt seems desirable that the deci- 3 See Eng. News Sup., July 9, 1903. Classification ' 343 sion as to the classification of material should when practicable be based upon its economic working, which is generally a question of judgment and therefore a matter for honest difference in opinion. The News suggests that it would seem better to have samples of the various ma- terials on file as the basis for the contractor's proposal. Even with this provision, the grading of material from one class into another may sometimes still lead to differences of opinion, misunderstandings and disputes. § 207. (C) Qualities of Material. Examples: a. Embankments: — "All material for the embankment shall be gravel, clay or earth, free from all organic matter, and be such as the engineer will approve. Any material used in said embankment and not so approved shall be removed by the contractor at his own cost and expense, and shall in no case be estimated or paid for." b. Refilling trenches — "Material for refilling. — The trenches shall be re- filled with the excavated material provided it be of proper quality, but in case insufficient suitable material is thus obtained, that which is suitable shall be furnished by the contractor, without charge, and he shall remove from the ground or uniformly spread over the surface all material which is not used in filling." c. Refilling in rock excavation. — "In refilling trenches from which rock has been excavated, the six inches below the pipe shall be filled with sand, earth or loam, and carefully packed before the pipe is laid; and the trench around and for eighteen inches (18") above the pipe shall be filled with earth, properly tamped, above which the rock may be filled in, but no rock containing more than two hundred (200) cubic inches will be allowed to be used in the filling." d. Reservoir embankment. — "No material shall be used which is not free from vegetable soil, roots or non-mineral matter. All stones more than one inch thick or more than three inches in maximum dimensions, shall be removed from the embankment before setting." As noted in the Engineering News Supplement * the last clause is an unusual and unnecessary requirement which will entail close inspec- tion and extra expense. The usual limiting size for stones in reservoir embankments is four inches in diameter, and even such a limit seems entirely unnecessary in work of considerable magnitude, unless the ma- terial conta'ns a superabundance of such material. § 208. (D) Quantities and (E) Measurements and Estimates. Examples: a. Embankments: "Measurements. — The measurement of all material used in the embankment shall be made in the embankment." b. Levees'. Estimate of quantities. — "The solid contents of the levee, com- puted to the established permanent grade and cross section only, will hi paid for. Nothing will be allowed for shrinkage. The cost of clearing, grub- 344 Specifications for Processes bing and breaking the surface shall also be included in the price per cubic yard for embankment." c. Canals: ^'Measurement. — Measurement for all excavated material will be made in excavation by the cubic yard of twenty-seven cubic feet, based upon the survey and cross-section notes of the engineer. "All 'glacial drift' excavated under the direction of the engineer, whether in or out of the main channel, will be included in the measured quantities. " 'Solid rock' excavated within the limits of the dimensions and grade of the main channel, or of any river diversion channel, or for the placing of any bridge or other structure, as hereinbefore specified, or that shall be taken out by direction of the engineer, shall ba included in the measured quantities, provided that nothing will be included for rock that comes out below grade in the excavation of any channel. "The prices given herewith are to include all work herein specified as clearing and grubbing, levees for protection, pumping, roadways for work- ing, back filling of retaining walls, and generally all work and material found necessary in prosecuting this contract." (Spec, San. Dist. of Chicago.) d. Tunnel excavation.— "Kxcayation either in earth or rock shall be estimated of a diameter only as great as the outside of the specified walls of the shaft or tunnels. Any material resulting from caving, careless blasting, or any cause by which material shall be removed from beyond the lines specified, shall be removed and refilled with suitable clay thoroughly rammed in place J and at the contractor's expense." § 209. (F) Shrinkage. — Material when moved from its natural bed usually alters in volume, sometimes to a considerable extent. Earth when excavated and placed in an embankment usually shrinks, frequently as much as ten per cent of its original bulk. Rock on the other hand when broken and placed in a fill, increases its bulk on ac- count of the voids between the pieces. This change in volume becomes important in considering earth and rock work. Earth work, if meas- ured in embankment, will measure less than if measured in excavation, tmless allowance is made for shrinkage. Embankments tniless carried above the permanent grade will prove deficient except where extra ma- terial is furnished. Rock work will occupy a much greater space than in the bed from which it was taken. EA'QDiplcs: a. Measurement. — "When earth work, taken from borrow pits, is meas- ured in embankments, an allowance of ten per cent, for shrinkage shall be made, and the net embankments will be estimated as ninety per cent, of the gross excavation." b. Provision for Shrinkage. — "One-tenth shall be allowed for the settle- ment or shrinkage of all embankments, regardless of the character of mate- rial used, or the method of construction, and no embankment that is not car- ^Vol. 50, p. 229. 5 Concrete filling may be required and if so should be specified, Extra Excavation 345 ried up one-tenth higher than the established grade shall be paid for. The allowance for shrinkage must be deposited on the crown and slope during the original construction in such a manner as to give the w^idth of crown and the slope required, which slope shall be uniform from top to toe of fill." § 210. (G) Extra Excavation, — It is necessary to anticipate the possibility of a greater amount of excavation than that which would be estimated from the plans for an improvement on account of the fre- qtient necessity of removing material which may be objectionable or to reach a more satisfactory foundation. In foundations for pavements, the following specification is often used : " "All clay and spongy material shall be removed to a depth to be deter- mined by the engineer, not exceeding 12 inches below the bottom of the foundation, and shall be replaced v/ith such material as the engineer may direct." This specification is faulty for two reasons : ( i ) It does not de- scribe the material with which the fill is to be made: (2) It does not provide for extra compensation when such filling is required. If the spongy material is to be replaced by sand, gravel or cinders, it should be so specified. If the fill is to be of clay, the specification should be equally explicit ; the source from which it is to be obtained should be specified, and a sample of the same should be provided so that there will be no uncertainties as to the character of the material which the engineer will accept. While it may be desirable to avoid a bill for extras, it is seldom that extra expense is really avoided by requiring the contractor to as- sume risks for extra work for which he is to receive no compensation. A few test pits along the line of the work will give the necessary in- formation as to the occurrence of tmsuitable material for the founda- tion, and an allowance can be made in the original estimate for the cost of extra filling, and a bid for the same reqtiired when the work is let. In this way the contractor is relieved from hazard and can and will submit a lower proposal for the work. Examples: a. General: "All excavation deeper than shown on the drawings, and all extra excavations ordered by the engineer shall be estimated and paid for at the contract price." b. Grading for Pavements: "All material more than eight inches below the established grade, together with all material excavated from above the grade of the finished pavement shall be classed as extra excavation and paid for at the price of such extra excavation named in the accepted proposal. The cost of all other excavation including all necessary excavation for curb- ing shall be included in the prices named for paving and curbing." '^ See Eng. News Sup., Vol. 50, p. 257. The specification "such material as the engineer may direct" is indefinite and unfair. 346 Specifications for Processes c. Excavation for Trenches: "Any increase in depth beyond that which is necessary to lay the pipes in the above described manner, if ordered by the engineer, shall be paid for at the price bid per cubic yard for extra earth excavated and backfilled; provided such extra depth average at least three inches the whole length of extra cut. A corresponding deduction will be made for ail length of less depth than that specified, but no attention will be paid to an average less than three inches for the whole length of such trench. The contractor shall also make additional excavation whenever re- quired for the purpose of securing a good and satisfactory foundation, for which work he shall be paid the price bid for extra excavation." § 211. (H) Extra Material and Borrow Pits. — Extra material that cannot be obtained from the location of the work is frequently needed for embankments and fills. In most work the land from which such material can be obtained is provided, but occasionally it may be desirable to depend on the contractor to secure such extra material from sources which he shall provide. Examples: a. Contractor to Furnish Material. — "The contractor shall make all nec- essary arrangements to secure the material for the embankment and no ma- terial shall be taken from the public streets or highways except as removed in the necessary grading." b, Borroiv Pits Provided. — "All necessary land for borrow pits will be provided by the party of the first part." § 212. Operations. — Under this heading should be included all specifications in reference to the necessary operations by which earthworks are to be begun, prosecuted, and completed, including also all restrictions and necessary precautions which are to be taken in order to secure good work and protect public life and property and the work itself. (A) to (E) Inclusive : Beginning Work, etc. (A) Dredge Work: ''Beginning Work. — The work shall be begun at the outlet, but the contractor may leave such temporary dams as may be neces- sary to hold back the water for the dredges, provided such dams are removed as soon as the progress of the work permits." (B) Grades and TAnes. — "The approximate depth of the excavation will be given by the engineer before the excavation is begun. Grade and line will be given by the engineer every 12 V, feet at the bottom of the trench, on stakes to be set by the contractor." (C) Clearing and Gruhting: a. For Levees. — "The ground to be occu- pied by the levee must first be cleared of all trees, stumps, logs, bush, weeds, and all perishable matter of every kind. All trees and stumps shall be grubbed out by the roots, and all work shall be done to the full satisfaction of the engineer." b. For Reservoir. — "The entire surface of the ground on which the reser- voir is to be constructed shall be cleared and grubbed of all trees, stumps, bushes and roots. All such material shall be removed from the reservoir operations 347 area. All good timber shall be cut and corded, and shall be and remain the property of the city. All debris shall be burned or otherwise removed from the city property." c. For Canal. — "The contractor will be required to remove all trees stumps, buildings, fences, or other incumbrances within 150 feet of the cen- ter line of the channel, or that may be in the way of any collateral or subsid- iary work herein specified. All such material of value shall be the property of the contractor, and all worthless material shall be disposed of as directed by the engineer. The cost of this work shall be included in the prices for excavation as hereinafter stated." (Spec. San. Dist. of Chicago.) (D) Breaking Surface for Levee. — "The entire surface which will be used for the base of the levee shall be thoroughly broken with a spade or plow in order to form a satisfactory bond with the earth fill." (E) Changes in Roads and Railroads: ''Railioay cTiawfires.— Throughout such sections of the work as may require a change in location of any rail- way, the contractor shall grade a double track road-bed with material from the excavations herein before specified, said road-bed to be thirty (30) feet wide on top, with side slopes of one and one half to one, and conforming in height and location and in other particulars to the plans of the engineer as shown on plan *2 a,' and the cost of any such work shall be included in the prices for excavation hereinafter stated. ( Spec. San. Dist. of Chicago.) § 213. (F) Consolidation, Rolling, Tamping, etc. a. For Reservoir Emhankment. — "The embankment shall be built by dumping the material in uniform layers and to the full width thereof. The material so deposited shall be spread out in uniform layers not over twelve inches in thickness and thoroughly rolled with a road roller of approved weight and dimensions." b. For Levees. — "The movement of all wagons, carts or scrapers used on the work shall be so directed that all parts of the embankment shall be made equally and uniformly compact." c. For Pavements. — "The sub grade, after being properly puddled and brought to the proper section, shall be thoroughly compacted by rolling and tamping in such a manner and to such extent as the engineer may direct. The roller shall not be less than three (3) feet in diameter, or more than six (6) feet wide on the face, and shall weigh at least eight (8) tons, and it shall be so operated as to roll the entire sub grade between the street curbs. All places that have not been or cannot be properly rolled, shall be tamped with square hand tampers of not more than twelve (12) inches square face, and not less than ninety (90) pounds weight. The rolling and tamping of the foundation shall always be kept at a distance of not less than one hun- dred (100) feet ahead of the pavement." d. For Pavements. — "When the road-bed has been brought to sub grade and before the curbs are set, and after the city has made any necessary im- provements, the sub-grade shall be thoroughly rolled with a steam road roller, weighing not less than ten tons. Any soft and spongy places that may appear during the rolling, shall be filled with dry earth or old macadam and be rolled until they are firm and solid and conform to sub grade, being sixteen (16) inches below the finished surface," 348 Specifications for Processes e. Tamping Trenches. — "In refilling the trenches, the earth fill in the bottom of the trench under, around, and six inches (G") over the top of the pipes and other castings, shall be carefully packed and well rammed with, proper tools for the purpose. Care shall be taken to give the pipe a solid bearing throughout its entire length. The earth filling above the pipes shall also be sufficiently packed to prevent serious after settlement. The contractor shall not be required to tamp the entire refilling, but the street shall immediately after refilling be put into a passable condition and kept so for the limit of guarantee; a crown being left over the trenches of not to exceed six inches (6") in the width of the trench, and solid enough to prevent a horse or wheel from sinking into it to a dangerous extent, of which the engineer shall be the judge. After rains, or at other times when any settlement occurs, either in the surface of the fill, or by the formation of holes beneath the crust, the trench shall be refilled and redressed, and all kept in a satisfactory and passable condition. "The back filling shall be done as soon as possible after the sewer is completed at any point. The earth shall be placed carefully in layers of not over nine inches in thickness, and each layer, before the next is placed, shall be thoroughly wet or rammed as the engineer may direct, and the filling shall be packed and rammed under and around the sewer, with proper tools, so as to effectually prevent all injury from settlement to the sewer, or of unusual repairs to the streets." f. Consolidating Trenches: "(1) In refilling the trenches the earth on each side and six inches over the brick work shall be carefully laid in so as not to disturb the work, and solidly rammed. .After this, the center may be struck, but no more load shall be placed on the arch until such time as the engineer may direct. "(2) Special care must be taken in filling around the sewer to keep the earth the same height on both sides. "(3) The first layer shall be placed in with shovels, and the sewers shall not be walked upon until this is done. The earth then to be thoroughly rammed in eight-inch layers, with in no case more than tv/ice the number of men refilling than there are ramming. "(4) The balance of the trench may be filled in the same manner, or by sluicing with water, as the engineer may direct." § 214. (G), (H) and (I) Limiting and Protecting Work. (G) Limits of Work: "In no case shall the contractor be allowed to work any trench more than four hundred (400) feet in advance of the pipe laying unless otherwise permitted in writing by the engineer, and in all cases the refilling shall be kept within 200 feet of the completed pipe laying, unless otherwise given in writing." (H) Bracing, Sheeting and Shoring: a. Shaft and Tunnel. — "The contrac- tor shall furnish and place all necessary bracing and shoring for preventing caving in the shaft, or tunnels to be built under this contract. The con- tractor shall so protect his work from caving that it shall cause no settle- ment or injury to the walls of the pumping station or reservoir, or to the foundations of the same, or to the foundations of any machinery installed Operations 349 therein, and he shall make or cause to be made, or shall pay the cost of mak- ing any repairs to the city property damaged directly or indirectly by his operations." b. Sheeting Excavation. — "In all cases when necessary to prevent the caving of banks, the contractor shall furnish and put in suitable bracing or sheeting at his own expense and remove the same when the trenches are refilled." c. Removing Bracing, etc. — "Before the refilling, all shoring, bracing, etc., shall be removed from the trenches, but shall be removed only as the filling progresses in order to keep the trench from extensive caving." (I) Protection, Care and Maintenance of Traffic: a. Bridging Trench. — "Should occasion require on any of the business streets, or in any street, the importance of which as a thoroughfare is great enough to make it neces- sary to do so, of which the city shall be judge, the contractor shall properly bridge the trench to permit a safe crossing of traffic." § 215. (J) Obstructions. — Improvements Encountered. a. Obstructions. — "When necessary to cross or interfere with existing culverts, drains or pipes of any kind or description which may be so located in said streets, or any railroads, side tracks or other constructions, which may be located in said street, notice shall be given to the city, and the work shall be done in accordance with the direction of said city or its represen- tative. All objects requiring it shall be sustained in place until the work is completed and any damage caused shall be thoroughly repaired, and all work requiring strengthening to meet any additional strain caused by such excavation shall be properly made by the contractor to the full satisfaction of the city. "All repairs of injury to pipes, drains or other obstacles encountered in or on the street, shall be properly made before filling over and around the same." b. Replacing improved surfaces. — "In all cases the class of pavement before existing shall be carefully replaced so as to be in every way equal to the original surface in material and workmanship as far as practicable. In improved streets and through the business portion of the town, the contractor shall thoroughly tamp the material from the pipe to the surface so that no after-settl6ment shall occur." c. "The contractor shall do whatever may be necessary to keep in posi- tion, and to protect from injury all water, gas pipes, service pipes, lamp posts, poles, and all other fixtures which may be encountered in carrying on the work. In case any of the said pipes, posts, poles, or other fixtures be damaged, they shall be repaired by the parties having control of the same, and the expense of such repairs shall be deducted from the amounts which may become due the contractor." § 216. (K), (L), (M) and (N) Pumping Methods, etc. (K) Pumping and draining: a.

He shall provide for all waterways, ditches or sewers intercepted during the progress of the work, and replace them in as good and satisfac- tory condition as they were before they were disturbed, before the work will be accepted." b. Shaft and Tunnels. — "During the construction and until the work is completed and accepted, the contractor shall promptly and properly dispos3 of all drainage water seeping into the shaft or tunnels by doing all necessary pumping and bailing, and he shall furnish all necessary machinery and ap- paratus therefor." (L) System of Excavation: a. Trenches. — "All excavation shall be done by open cut from the surface. Trenches for pipe sewers, shall be eighteen inches wider than the diameter of the pipe. The bottom of all trenches, whether for pipe or brick sewers, must be as far as practicable excavated to the exact form and size of the lower half of the pipe, or sewer, to be laid therein. Suitable holes shall be cut for the pipe, bells, and for the proper fitting of all junctions when needed." b. Tr'enching. — "The excavation will, in all cases, be continued from the surface to the bottom line of the same, unless otherwise specially permitted in writing by the city. The trench shall be properly and smoothly bottomed so that the pipe will have a full length support. In excavating through improved street surfaces, the material shall be carefully removed and kepi free from the other material excavated from the trenches. "In order to facilitate traffic and interfere with the use of the public streets as little as possible, all trenches having an average depth of eight feet or more shall be excavated by the use of an overhead conveyor system with which the material excavated on one portion of the work shall be dumped directly into the trench in which the sewer is already completed. (M) Filling '. Aqueduct Embankrnents. — "The material is to be deposited and spread in horizontal layers not exceeding 3 inches in thickness, each layer to be sufficiently watered and very thoroughly rolled with a heavy grooved roller. From time to time during the construction of this portion of the embankments, and if so required, three times after its completion, this portion shall be so thoroughly saturated with w^ater that it will stand upon the surface. "The building of the aqueduct upon such foundation embankments shall not be begun until they have stood six weeks after completion, unless other- wise directed. (Met. Water & Sewerage Board.) (N) Drilling, Channeling, Blasting and Quarrying: a.

All blasting shall be carefully covered and all blasts shall be fired by moms of electric igniter and detonating caps, and not by fuses." b. Canal — "The contractor is to furnish all explosive compounds for blasting the material provided to be excavated under this contract; and, whereas, the storing, handling, and use of so large amount of explosive material requires the utmost care and discrimination, it is therefore under- stood and agreed that the said contractor shall arrange for the storage of all explosive material at a distance not less than 600 feet from the work, or from any other magazine, or from any dwelling occupied as a habitation. Operations 351 and that not more than 5,000 pounds shall be kept in one place. It is fur- ther understood and agreed that said explosive material shall in no case be brought unto the work except when needed for the purpose of charging the blast holes, and then only in such quantity as is needed for the particu- lar work in hand, and that none but skilled and careful men shall be em- ployed in the handling or use of said explosive, and that no liquid explosive shall be used. "It is further understood and agreed that the ground surrounding all magazines shall be kept free of vegetable or combustible material for a radius of one hundred feet, and that their walls shall be bullet proof, to a height of one foot above the contained explosives, and that in no case shall they be made of brick or stone. It is also understood and agreed that such signals of danger, as may be directed by the engineer, shall be given or displayed before the firing of any blast, and that the said contractor shall conform his acts to and obey all rules and regulations relative to the hand- ling of explosives and the firing of blasts, for the protection of life or prop- erty, which may be made by the engineer from time to time."

CHAPTER XIX SPECIFICATIONS FOR MACHINERY AND APPARATUS § 221. Divisions. — Specifications for machinery and apparatus may be divided into three classes. First. General specifications are usually prepared for occasions when it is proposed to purchase standard designs of manufactured ma- chinery. Such specifications should definitely designate : A. The kind and number of machines to be furnished. B. The purpose for which they are to be used. C. The capacity. D. The condition of operations. E. The conditions of delivery, foundations and erection. F. The tools and appurtenances required. G. The time of delivery. H. The specification may also include such other special require- ments in regard to type of machine desired as w'U confine the b'dders to the machine more nearly fitted for the requirements of the condi- tions. /. The requirement of full specifications from the bidder as to the particular characteristics of the machine he proposes to furnish. Second. Detailed specifications are usually prepared for occa- sions when it is proposed to purchase machines which are designed by the manufacturer but which are manufactured to order and are more or less special, in accordance with the demands of the purchaser. Such specifications not only accurately define the requirements outlined under "General Specifications" but also describe at consid- erable length the requirements for material, workmanship, finish and strength of all or the principal parts of the machine to be furnished. Third. Design specifications are usually accompanied by com- plete detailed plans, and designate definitely and minutely in full de- tail every part and portion of the machine to be provided, describing the material from which it is to be made, its qualities and strength, the workmanship and finish, and the weight, size and dimensions of all parts. The above divisions are more or less arbitrary and in practice vSuch specifications often grade imperceptibly from one to the other. 358 Specifications for Machinery § 222. General Specifications. — In general specifications for ma- chinery and appurtenances, all essential requirements of the machine needed, and the work to be done by it, should be specified. These should be given in sufiicient detail so that manufacturers may under- stand what class of machinery is desired or what class is best adapted to the work. In such specifications, all general requirements that are fixed by the conditions should, so far as possible, be specified. If the machine must be horizontal or vertical, if its size must be limited, or if there are any other requirements which are definite and can be fixed, they should be stated. The conditions of installation and the other requirements for a pump will usually determine whether it should be a steam pump or a power pump, and if the latter, whether it should be reciprocating or centrifugal. If a powxr pump is re- quired, the prime mover to be used is usually known, and whether it will be operated by rope drive, belt or by direct connection. The requirements for a steam engine will usually determhie whether it should be simple or compound, condensing or non-condens- ing, and probably define certain other features which should be spe- cified. Unless the specifications limit the most common details, the bids under them will often embrace an exceedingly great variety of ma- chinery which will differ widely in the manner in which it will fulfill the requirements. Such a multitude of proposals for a great variety of machines, differing widely in character, will be difficult of com- parison even when the engineer is thoroughly familiar with the type of machinery in question and with the effect of changes in design on the economy of operation, and will leave the novice or those unfamiliar with the machinery greatly perplexed. General specifications, where few or no details are included, arc best adapted to occasions on which the competition can be limited to manufacturers known to be responsible and experienced, and whose line of goods can be taken largely on its merit with little or no ques- tion in regard to the character of material or of details. Where, as in the case of public lettings, the condition must be opened to all, and the award must be made to the lowest responsible bidder, such specifications do not offer a sufficient protection to the purchaser, and greater detail is essential. For such lettings, it is nec- essary to protect the purchaser from unscrupulous bidders, and the specifications must be drawn so compiete as to prevent the use of im- proper material and construction. General Specifications 359 Limiting Details. — It is usually undesirable, except in special cases, to limit in great detail the dimensions of the parts of standard machinery. The standard machines of all first class manufacturers possess characteristics peculiar to that maker, characteristics on which much of the success of the machinery often depends, and on which the reputation of the manufacturer has been established. Specifica- tions requiring changes in such designs should seldom be written, and then only when the peculiar local conditions absolutely require such changes. If the type of machinery made by such a manufacturer comes within the requirements of the case in hand, the specifications should be drawn so broadly as to admit the use of the valuable features of all first class makers. For example, in pump and engine specifica- tions, it is usually undesirable and unfair to specify certain exact cyl- inder sizes and dimensions for, as a rule, no advantage will result, and the manufacturers whose standards are different are greatly and un- justly handicapped thereby. Similar unnecessary requirements con- cerning the exact dimensions of other portions of an engine or of other machines should be avoided. § 223. Selections. — Where specifications are general and not specific, the standing and experience of the maker become important and an investigation of his general reputation, the length of his experi- ence, the facilities he possesses for manufacturing, and the design and workmanship of the machinery ordinarily made by him, is desirable. Frequently, extensive manufacturers of a certain class of machinery make a specialty of a certain type or capacity, and in such cases may not have the experience necessary for the successful manufacture of ma- chinery of a different type or capacity. A machine furnished and manufactured by such parties often possesses the general characters of experimental work, and is likely to be only partially successful. Letters and references are of little value in this connection, unless carefully investigated and found to be from responsible disinterested parties, and based on a class of machinery similar or identical with the class needed for the particular purposes at hand. § 224. Detailed Specifications. — The preparation of detailed specifications departs from the general specifications only in the elabora- tion of the specification of details. Detailed specifications for standard machinery can generally be drawn in such a manner as to avoid the necessity of requiring special machines. The general details adopted by first-class manufacturers can be specified, and, where practice differs, specifications may be so 360 Specifications for Machinery drawn as to admit the alternative of two or more first-class methods of manufacture. Such a method manifestly demands an intimate knowl- edge of correct practice, but such a knowledge is always necessary for correct specification writing. Considerable experience with the particular kind of machinery or apparatus in question is necessary before the engineer should venture to issue specifications in great detail. The builders of first-class ma- chinery, who are usually men of extensive experience, are slow to take contracts to manufacture machinery which is more or less special, and which may depart radically from the types or details they have found most desirable in their own line. Usually such specifications should be confined to requirements for workmanship and material, ample dimension and strength, and other requirements which will assure first-class construction and economy of operation without modifying seriously the fundamental design of the manufacturer. § 225. Design Specifications. — When plans for a machine of new design are prepared, full and detailed specifications, describing the character of material and workmanship of each part, are essential and should accompany the working drawings. Such specifications admit of great elaboration, but even in these cases the design and specifica- tions should be kept within standard commercial lines with regard to sizes of rods, bolts, etc., wherever possible. Such specifications re- quire an intimate knowledge of the principles and practice of design and manufacture, and should be attempted only by the practicing en- gineer of experience. Contracts for special machinery of any kind can, of course, usu- ally be placed, if such machinery is essential to the particular installa- tion in view. Competition for such work however is limited, and the expense of departing from regular designs is often so large as to to make the price of special machinery considerably greater than that of regular types. This is essentially true of machines that can be classed as "standard," which are in general use and are manufactured in large quantities. In other classes of machinery and apparatus which are simple in design and more or less special, it is sometimes found that a considerable saving can be made over prices demanded by manufacturers for the adaptation of their special designs, by the preparation of detailed plans and specifications for the manufacture of a particular machine for a special purpose on carefully selected and economical lines. § 226. Preparation of Specifications for Machinery. — In general, whenever a specification is prepared for any particular machine, it Preparation of Specifications 361 must contain certain information which will be necessary as a basis for any intelligent proposal for the same. Every specification must be complete to this extent, even though it be in the simplest possi- ble form, such as a letter of inquiry for prices on the machine desired. From such a simp'e form, the specifications may be elaborated to the extent that the engineer finds it desirable to be more explicit as to his requirements for certain specific features, and even to the extent of including full detailed specifications (together with full detailed plans) for the size, dimensions, material and workmanship for each and every part of the entire machine. In considering the simplest requrements for machinery specifica- tions on which an intelligent bid may be made, certain data are found to be absolutely essential and certain other data are desirable. These may be classified as : A. Specifications which must always be included, and B. Specifications which should be included when practicable. In the preparation of specifications for machinery or apparatus, it is essential, especially for the young or inexperienced engineer, to prepare an outline for the general requirements which should be em- bodied in the specifications for the machine or apparatus under con- sideration. The manner in which this may be done is shown 'n the following outlines which have been used for some years by the author in his own professional practice. § 227.

The Specifications. — After the preparation of the outline previously described, the engineer should prepare with great care the specifications for the machine or appliance desired. All that has previously been discussed in regard to the writing of specifica- tions should be kept fully in mind, and everything should be done that will insure the specifications being full and complete, clear and explicit. If the outline has been prepared with care, the atten- tion of the engineer can be confined to the preparat.on of the spec- ification in carefully worded and exact language which will assure a clear interpretation of his requirements by the elimination of all indefinite, indeterminate and ambiguous language, and if all arbi- trary, unfair and unnecessary requirements are eliminated, he will be reasonably assured of low and intelligent proposals. The fol- lowing statement of the requirement of general specifications and the examples given will still further illustrate the matter and ar- rangement suggested. § 240. General Specifications for Machinery. — When general specifications for machinery are to be issued they should include the following : ( For examples under each heading see specifica- tions following for steam engines and boilers.) i 378 Specifications for Machinery 1. Extent of Work. — In this specification should be defined in general terms what is required under the contract, including : A. The furnishing of the machine, or number of machines re- quired ; B. The point of delivery ; C. The preparation of foundations, and by whom ; D. The erection, and by whom ; E. The various furnishings, tools, fittings and equipment re- quired with the machine. 2. Capacity. — Under th!s head, the capacity of the machine should be specified. This specification should define the amount, quantity or rate of work which the machine will be required to do or accomplish in a specified time. 3. Service. — Under this head should be included the specifica- tions regarding the pressure or intensity under or against which the machine is to operate. This would include, in steam driven ma- chinery, the steam pressure to be furnished to operate the machine, and in pumps, compressors or electrical generators, the pressure against which the machinery is to operate. 4. Type of Machinery. — In many classes of machinery, special types of machines are capable of operating with a greater or less degree of economy, and wherever possible the selection of the type of machine should be made by the engineer preparing the specifica- tions, without necessarily entering into the details of construction. When the type is given, the variation in the bids received is largely limited, and the selection of machinery becomes more particularly a question of price than where a large variety of types are consid- ered. 5. Furnishings. — This specification should cover a description of the accessories, furnishings and fittings which are to be supplied with the machine in question ; it should include any auxiliary ma- chinery or apparatus and appliances which are desired and which are not normally a part of the machine. 6. Design. — This specification should cover the details of the machine which are either definitely specified or which are to be left to the manufacturer to select in accordance with his own practice. The elaboration of the specifications for type and design is the es- sential feature in which the detailed specification varies from the general specifications. General Specifications 379 111 general, the design of any machine should be — "such that all working parts shall be readily accessible for inspection and repair, easily duplicated, and readily replaced, with each and every part of the machine properly designed and suitable for the uses and service required." 7. Drazvings and Plans. — This specification should describe the plans to be furnished by the bidder. These should usually include foundation plans, showing the general plan or outline of the ma- chine, including its general dimensions, with the location of all con- nections, and this specification should also require the furnishing of catalogues or photographs showing the machinery under considera- tion in satisfactory detail. A specification requiring the furnishing of detail working plans is not usually advisable. Most responsible manufacturers rightly refuse to part with such drawings which are largely the work of their extensive experience and are of too great value to be made public property. In special work, however, or when the manufacturer is present- ing a newly designed and untried machine, a requirement for the production of the detailed plans is often advisable, and may be nec- essary for safety. Such a requirement is useless, however, unless the engineer is sufficiently acquainted with machine design td be able to criticise intelligently the designs when so presented, and in other cases the reputation and experience of the manufacturer must be the main safeguard. 8. General Guarantee and Insurance. — Under this head should be included a clause similar to the following : "The contractor guarantees the design, workmanship and material to be as described and specified herein, and also as described and specified in the detailed specification hereto annexed and hereby made a part hereof. "He further guarantees that all work and all material in said machinery shall be of the best quality and first-class in every particular. "He further agrees to replace any portion of said machinery shown de- ficient by the tests to be made on said machinery, or otherwise, or which shall within one year thereafter fail on account of being deficient in work- manship or material." 9. Detailed Specifications. — This specification should require the manufacturer to furnish detailed specifications covering all features of the machinery, including workmanship and material, with such guarantees in regard to regulation, operation or economy as are to be required from him or given by him.

Payments. — No payments shall be made until the plant is erected, tested and accepted, and if the engine shall not prove in the specified test equal in all particulars to the guarantee, then and in that case, the party of the first part shall have the right to use such plant for a period of time sufficient to allow them to purchase and erect another plant of satisfactory design, and the use of such re- jected plant under the conditions above named shall be without ex- pense to said party of the first part otherwise than the cost of oper- ating the same. The agreed price will be paid by the party of the first part when the plant is tested and accepted. § 243. Selection of Machinery. — In the selection of machinery or apparatus it is usually desirable, so far as practicable, to choose those designs which have actually been developed and which have proved sat- isfactory by actual use under wide range of conditions. The use of the new designs which have recently been developed, even by those who have had extensive experience with similar designs but of a different kind or capacity, is attended with considerable risk. One of the early personal experiences of the writer will perhaps serve as a typical illustration of the unfortunate results of the failure to observe this precaution. A factory was built for the manufacture of certain clay products from which a somewhat unusually large capacity was desired. Ma- chinery was available from two sources. In one case, the manufacturer had a large number of machines of the capacity required in successful operation under a wide range of conditions ; in the other case, the sec- ond manufacturer had many similar machines in local and successful use, but of only one-half the capacity required. The second manufac- turer desired to develop a machine of greater capacity and pointed out their wide experience with the smaller machines and the ease and safety with which they could enlarge the capacity and develop a machine which should be perfectly successful. This they agreed to do at a price of less than one-half the price demanded by the first manufacturer. The de- velopment appeared so simple that the lower bid was accepted, and the Selection of Machinery 387 machines manufactured and installed. The results were a season spent in a constant repair of breakage, and consequent shutdowns, occasioned by improper design. The output of the factory was decreased for the season by at least one-half, and although the manufacturer finally de- signed- a satisfactory machine and furnished a new unit to the factory without further compensation, the delays and repairs exceeded the original cost of the machine many times and entailed a heavy loss which might have been eliminated if the more expensive but fully developed machine had been selected. The second manufacturer learned how to design and construct his machine at the expense of the factory which used the first design. Such experience is not uncommon. Experience must be paid for, and it is usually much more economical for the individ- ual to pay for the experience of others by a higher cost of equipment than to pay the larger expense of personal experience. Guarantees of replacement of a machine, should it prove unsatis- factory, are often easily obtained but it is seldom a manufacturer will undertake to pay the consequent damages, and the prospect of such damages when an undeveloped machine is adopted, is usually too great to warrant its installation even at a greatly reduced price. CHAPTER XX DESIGNS AND SPECIFICATIONS FOR ENGINEERING AND ARCHITECTURAL WORK § 244. The Investigations. — Prior to the design of any plant or structure a thorough investigation should be made of the nature of the material which must be excavated or moved, of the foundation on which the structure must rest, and of the material into or through which tun- nels, channels, foundation piles, caissons or other structures must be driven. The character, the quantities and the physical conditions of such materials should be determined so far as practicable. It is often the case that the decision to build or to carry out an improvement is followed immediately by a demand for construction at such an early date that a proper examination of the conditions is not possible. Such haste in construction is undesirable and almost invariably entails extra expense. The failure to make suitable investigation of these conditions and to secure the desirable information, both for the use of the engineer in designing and estimating the cost of the work and for the use of the bidder in the preparation of his proposal, is often due to false economy on the part of the owner or of the management of the company who proposes to construct the work. The cost of thorough preliminary in- vestigation is often considerable, and it is sometimes assumed that any extensive preliminary examination is unnecessary. When the en- gineer yields to necessity or persuasion and fails to secure the proper information, he is nevertheless blamed for any trouble and expense which may follow. If the bids received, based on insufficient informa- tion, are unduly high or if the quantities estimated on the same uncer- tain basis are found seriously in error, he is blamed for troubles which he has had no means of preventing. Preliminary information will permit plans to be drawn to fit the actual local conditions, instead of assumed conditions which do not ob- tain and will save needless expense and much more than enough to pay the preliminary costs, to say nothing of the efifect of such information in reducing the prices bid for the work. The engineer, therefore, should place the necessity for such preliminary investigations and the advantages which will accrue therefroni squarely before his clients, and insist on sufficient time and expenditure to secure the information Investigations 389 necessary for both purposes. The low bids received on ahiiost every job on which adequate information is furnished by the engineer to prospective bidders is proof of the saving effected in the cost of the work, and this is in addition to the saving accompHshed by the conse- quent proper design. Everything that can be done to make the con- ditions bearing upon the required work clear and certain has an ad- vantage in reducing the prices which will be bid for the work, and the converse is also true. § 245. Unsatisfactory Practice. — It is unfortunately common mistaken practice to require the contractor to assume all risk and re- sponsibilities concerning the character and sometimes even concerning the relative amounts of the different kinds of material. Good sense seems to warrant the conclusion that, in dealing with intelligent men something cannot be secured for nothing, and experi- ence has demonstrated that whenever such an attempt is made it usually results in unnecessarily increased cost. An intelligent contractor, if he bids at all on plans and specifica- tions which are uncertain or manifestly unfair, will add a sufficient sum to compensate him for the uncertainties and the unfair treatment he must expect, and to be safe will usually add more than enough to cover the probable expense. The client thus pays more, and usually much more, than he would under definite plans and specifications. When only incomplete investigations have been made by the en- gineer, contractors are usually invited to make their own investigations in order to determine the nature of the formation in or throusrh which the work is to be built. It is evident that such a policy is a poor one, for if carried out it involves cons'derable expense perhaps for each of a large number of contractors, all of whom must investigate the con- ditions to their own satisfaction. It is evidently desirable in order to avoid expense that only one such investigation should be made, that it should be made by the engineer of the parties letting the work and that it should be thorough and sufficient for the use of all parties interested. This question is an important one and one that has many bearings, all of which should be considered. That such unfair and unsatisfac- tory practice is quite common is evident from numerous specifications of which the following from a proposed contract for grading a railroad is an example '} "Contractors bidding on the work are invited, at their own cost and ex- pense, to put down test holes or borings, to determine the nature of the soil 1 See Eng. News Sup., Vol. 50, page 20. 390 Specifications for Engineering Work and underlying formation, and every facility will be given by the company to the contractors for that purpose." "It must be particularly understood that the bidding on this work will be without classification for excavation and grading, and that the contractor must personally examine the geological formation; and no claim upon the company may hereafter be made on account of misinformation stated to have been given by any employee of the Company or Board." It is evident that no intelligent contractor will assume uncertain- ties such as are involved in the above specifications without consider- able investigation and without expecting adec^uate compensation. A conservative contractor will probably refuse to undertake such an in- vestigation, because the chances of his securing the work are remote. The number of firms that will attempt to make such an investigation will therefore be small and the competition will be limited. Such firms will bid high enough to cover the cost of all possible contingencies, and the cost of the work will be unnecessarily increased. § 246. Difficulties. — To make a thorough investigation of the actual conditions on a project, to determine the quality and quantity of the various kinds of material to be encountered and to show them by plans, drawings and definite specifications, involves not only time and expense but also the responsibility for any accidental misstatement of the exact facts. Underground conditions are very uncertain and can- not be readily determined even by elaborate borings. Variations in the strata are liable to occur which will not be determined even though the borings are fairly close together and it is evident that such investiga- tions must have a practical limit. Any departure from the positive in- formation given may result in demands for extra compensation, and even slight variations which might not actually affect the cost of the work will give an unfair contractor an opportunity for excessive de- mands for extra compensation; whereas if the contractor is required to assume the responsibility for changes, no such claims can be main- tained. It is believed that this danger is one of the chief reasons why so much responsibility is frequently forced on the contractor, even when it is recognized that such responsibility entails extra expense. It is desirable to remove hazard to as great a degree as practicable, both in order to secure reasonable b"ds and for the sake of fairness. The owner must expect to pay a fair price for his construction under the conditions that actually obtain, and he will certainly be compelled to do so unless some mistake is made by the bidders. The technical problem involved is to determine and show by plans and specifications as nearly as possible the actual conditions that obtain in order to se- Difficulties 391 cure low prices through protection to the contractor in his bidding, and to protect the owner from unjust claims based on slight variations which do not affect the cost. This can often be done by determining the quality and kinds of material through sami)le borings and by ar- ranging to pay for possible variations in estimated amounts in accord- ance with their actual occurrence. In the excavation of trenches, tunnels, etc., a large item of ex- ])ense is the cost of handling the water that may be encountered. In many specifications the contractor is required to take the risk as to what this may cost. The removal or reduction of the risk is a relief to the contractor and will usually reduce the price bid for the work. Such a clause in tunnel work is occasionally introduced essentially as follows : "The contractor will be required to pump out of the upper section of the tunnel, 10,000 gallons per day of 24 hours, without charge, regardless of the amount of lift. -Any excess of water will be paid for at the rate of 1,000 gallons specified in the proposal. " 2 The last sentence in the above spec'.fication is objectionable on account of the fact that the amount of the excess water cannot well be estimated, and therefore no basis of comparison of various b"ds is pos- sible on this item. It would apparently be better to state in the speci- fication an amount which will be paid to contractors for each 1,000 gallons, although such a specification would probably be illegal in pub- lic contracts where the work must be let to the lowest responsible bid- der.^ Under such contracts, in all cases where the cost of any extra work is fixed at cost plus a percentage, or where provision is made for any incidental rock excavation or other contingent expense, at a cer- tain fixed price per unit, the payment for such work can be enjoined by a taxpayer. The only safe method therefore under public con- tracts is to ask for a percentage bid for extra work or for a unit price for any other contingent expense. § 247. Deep Wells. — In some cases, a complete investigation is evidently inexpedient. For example, in deep borings and in the drilling of deep wells, while the nature of the geological strata can in general 2 See. Eng. News, Vol. 52, p. 363. •" "When the law provides that the contracts for public work shall be let to the lowest responsible bidder, any provision in the contract which fixes the price for extra work without having invited bids on that item, is illegal, and payments at rates specified may be enjoined at the suit of the tax- payer."— Moynahan V. Birkett, S. P. 2, Dept. 31, N. Y. Supreme Court 293. 392 Specifications for Engineering Work be ascertained, these strata are known to vary to a considerable extent in character and thickness from point to point and no means of ac- curately determining their exact nature and extent are available ex- cept by the construction of the well itself or a smaller one in the im- mediate vicinity which would involve an expense very greatly in ex- cess of the benefit derived. In such cases, therefore, a statement of the approximate geological conditions seems desirable and, in general, the contractor should expect to take the risk of the uncertainties in the characters of the strata, and for which he must demand proper com- pensation. Provision should be made for the possibility of encounter- ing caving material, for which contingency extra expenses may be oc- casioned by the necessity for enlarging the well and casing off the caving material in order that greater depths may be reached with the desired well section. It will usually prove economical for the owner to assume the responsibility for this extra expense, for if he does not he will probably pay the extra cost in higher prices, whether or not the expense is actually incurred. § 248. Investigations for Sewers. — In investigations for sewers the nature of the material which will probably be encountered is usu- ally determined by borings or soundings. Such materials are often classified similarly to those in railroad excavation, and on this basis payments are ordinarily made. This limits the chances taken by the contractor and to a much greater extent than where he is left to es- timate the varying amounts of such materials on the basis of the bor- ings which have been made. The unevenness of the strata through- out the extent of the sewer system is so great that it is usually inex- pedient to take sufficient borings to determine with accuracy the amount of rock which will be encountered. The variations in rock should not be at the risk of the contractor so far as amounts are con- cerned, and the expense incurred in making the necessary borings will be more than returned by the lower cost. A clause in which the burden is thrown upon the contractor is as follows :* "The Borough does not warrant the correctness of the soundings as marked on the profile. The contractor must assume all risks resulting from any difference from the soundings found to exist when the sewer is built." In Sewer w^ork, the greatest item of uncertainty usually arises not through the question of rock or earth, but from the variation in the qualities of soil and through the presence of water. These materials may consist of: (i) earth more or less easily caving; (2) earth or 4 Eng. News Sup., Vol. 50, p. 305. Designs 393 clay consol dated and free from cavings ; (3) sand with or without water; (4) fine sand or quicksand and water. It is usually inexpedient for the engineer to offer the above clas- sification, and the questions of these materials and conditions, while they should be determined as clearly as practicable and given to the contractor as data for use in preparing his bid, must usually be at the contractor's risk. § 249. The Basis of Designs. — In every technical endeavor the object involved is the accomplishment of certain definite results at a minimum expense, cither immediate or ult'mate. If a structure is to be built both utility and a certain degree of beauty are usually involved. If permanent, it should not be unsightly, and its utility may demand any degree of artiste development from a plain but s'ghtly structure to those structures which are created only for their artistic merit. In each case, however, the object is to accomplish the maximum of utility for the minimum of expense. No unnecessary expense is warranted. The structure must be safe and the degree of safety must be measured by the possible disastrous results of failure. Factors of safety must be intro- duced and are made necessary by variation in strength of material, un- certainties of manufacturing processes and uncertainties of loadings and consequent strains to which the structure may be subjected and to various contingencies to which it may be exposed. The limitations of strength, and the extent to which artistic considerations will prevail will always be a question of experience and judgment, and while these should be fixed with intelligence, in most cases a doubt may remain as to whether their limits are too small or too great. Safety must be bal- anced against expense, and the expense considered must always involve both first cost and upkeep. In operating plants, questions of efficiency also arise ; first cost and upkeep are important, but the running expense must be considered, and greater expense of installation and maintenance may be warranted by greater or more satisfactory output. In all cases, a balance between expense and results must be struck and the technical man is responsible for establishing a proper equilibrium between these various factors. § 250. Design. — To design properly any structure or plant the designer must be familiar with the methods which must be used in construction in order that the construction shall be practicable and can be economically performed. The design and the consequent specifi- cation should not include unnecessary refinements or unreasonable re- ([uirements that will add to the expense without giving corresponding benefits. The design will have a large eft'ect on the cost of construe- 394 Specifications for Engineering Work tioii and this fact should be duly considered before arbitrary and un- usual details are finally adopted. Designs should be based upon the consideration of first cost, the cost of maintenance, and in certain cases, the cost of operation as well. Low first cost should not be se- cured at the expense of high maintenance or high operating expense but true ultimate economy should be considered whenever practicable. In some cases temporary construction can follow only with the development of the property. In plants which are to be maintained and operated there is a personal equation which must be considered. Who will operate and maintain the plant or structure? The capacity and ability of those on whom dependence must be placed for this pur- pose, needs careful consideration. High grade machinery and diffi- cult ma'intenance must not be trusted to incompetent men and where inefficient assistants must be utilized for such purposes, simplicity of design is highly essential. In the arrangement of an operating plant the same factors must be considered. If the plant is so arranged that the easiest thing to do is the right thing to do, it may confidently be expected that it will be done but not otherwise. It is not enough that a plant be well and economically designed and carefully constructed. It must also be easily maintained and readily operated by the class of men that can be secured for such purposes, and these factors are equal in importance to the other physical factors in shaping the design. The study for a design requires an extensive investigation of the various types of similar development that are in practical use and the adaptability of such designs to the conditions of the particular locality under consideration. It is seldom that plans, no matter how success- fully carried out in one place, can be duplicated to advantage in an- other. Each plant should be built to meet the particular conditions under which it is to be installed, maintained and operated, and the best ideas from all sources that will apply to the local conditions should be correlated and embodied in the proposed design. Extensive experi- ence, observation, and study are each desirable and essential for the best results. The structure Avhen completed should be suitable in every way for its purpose but no unnecessary expense should be incurred. The best of everything is not always essential or desirable. ''Reduction of first cost to the lowest possible point is in logical or economical order the first consideration ; although therefore not by any means either the most important or the governing consideration. That this is so is easily seen, however often forgotten. It is not only businesslike common sense for investors and their servants, but it i> Designs 395 sound political economy for the community as a whole. It does not mean nor imply cheap and shabby construction. It simply means an avoidance of waste, either in saving money or in spending it. It sim- ply means a recognition of the fact that every dollar and every day's work that goes into the ground and does not bring something out of it, makes not only the individual but the whole community poorer." -' For his own as well as for his client's good, the engineer should endeavor to secure the very best results possible when all things are carefully weighed and considered. No reasonable amount of consci- entious work, painstaking thought, study, labor or expense should stand in the way of such results ; and anything less than this is a detri- ment to future professional attainments, which no engineer, young or old, can afford. § 251. False Economy in Design. — In the building of shafts and tunnels, the cost of excavation and filling beyond the neat lines of the exterior of the lining is sometimes an item of considerable importance. In many cases, designers limit the excavation to these neat lines and in consequence the specifications require the contractor to assume all risks of extra excavation and filling and the extra cost must therefore be included in some other item of the proposal. In some cases, specifi- cations are so drawn as to divide the risk by inserting a clause provid- ing that any excavation beyond the neat lines, due to unavoidable falls and breaks, shall be paid for at a price which is usually named a little less than the actual cost to the contractor.^' By such means the con- tractor is assured of a certain compensation for all excavation and re- filling, but at a rate which will not make it an object to go beyond these lines on account of a high price for the required filling. In other cases the entire risk is placed on the contractor. In the specification : "Concrete lining will be placed throughout the tunnel as indicated by the drawing. Any excavation beyond the neat lines of the tunnel section as shown on the drawings, shall be filled to the satisfaction of the engineer and no allowance will be made therefor." not only is the risk placed on the contractor but the working is indefi- nite and therefore vmsatisfactory. The nature of the filling should be stated, whether clay, rock or concrete. It is easy for the engineer to here specify the character of the material that will be required and leave out the doubtful term "satisfaction." •'■. A. M. Wellington, Eng. News Sup., April 28, lfi04, p. 326. fi See Eng. News, Vol. 52, p. 362. 396 Specifications for Engineering Work It should be remembered that, while throwing the cost of this extra fill on the contractor may be an apparent saving in the cost of the work, in order to keep down the amount of additional extra work, extra cost may be involved. Extra cost may be caused. First: By drilling holes. Second: By the cost of powder and labor required to break rock to small size for loading. Third: By the cost of trimming projections from tlie side of shaft or tunnel. What is desired is the construction of proper work at the least ex- pense to all concerned, and the cost of a reasonable amount of break- ing beyond the neat lines may be more than saved in reducing the extra cost of careful excavation. The above is but a single example of how false economy may sometimes be attempted in the preparation of designs and specifications. § 252. Estimates. — Estimating the cost of structures and mate- rial is an important duty of the engineer. The financial success de- pends on the actual cost of such works and the works must be financed on the basis of these estimates. If the actual cost greatly exceeds the estimated cost, a project which may have seemed financially attractive may prove a financial failure ; and even if failure does not result the necessary refinancing may prove an expensive handicap. Plans are rarely made for large and important structures that do not require more or less modification during construction. Unless this fact is duly appreciated by the designer and liberally allowed for in the estimates of cost, the estimates will always be found more or less inadequate to complete the structure. The hazards of construc- tion increase with the difficulties of construction. In the superstruc- ture of one of the large buildings of Chicago, designed by one of the best architects of that city, and which was completed without any seri- ous mishaps, the cost of extras increased the original contract price almost twenty-five per cent., or about $700,000) on a $3,000,000 esti- mated cost. Engineering structures are sometimes built in locations where they are subject to considerable hazard due to conditions that cannot be fully predetermined and to the contingencies of storm and flood, which cannot be foreseen. In such cases the ultimate cost cannot be accurately determined and is frequently greatly understimated. The engineer designing a structure or plant, if unfamiliar with the contingencies of actual construction, can scarcely conceive the unforeseen circumstances which may and frequently will occur when Estimates 397 his plans are being carried out in the held. An estimate in detail of the reasonable cost of each feature of the work can seldom cover all the costs involved in the construction of such structure and the cost must be overestimated or a large contingent estimate must be added in order to cover the actual cost. An engineering project which will pay only fair returns on a close estimate of cost, is seldom worthy of serious consideration as unforeseen expenses will often make it a los- ing investment. In a recent water power development which was under advise- ment for a number of years, and which was perhaps as thoroughly considered and as carefully planned, both in design and in methods of construction to be pursued, as any other development of late years, the cost of the finished project exceeded the estimate by thirty-three per cent. The estimate of cost was about $2 1 ,ooo,(X>o ; the actual cost about $28,000,000. In another case, where estimates were carelessly made, the original estimated cost w^as $800,000, and the actual cost of the complete development about $2,500,000. It is of course obvious that a project which may be very attractive on a basis of an investment of $800,000 is likely to be a ser'ous failure on the basis of an investment of $2,500,000; and even a project which seems attractive on the basis of a $21,000,000 investment may be seri- ously handicapped by an expense of $28,000,000 unless there is a pros- pect of extraordinary returns on the basis of the original estimated cost. The unexpected extra cost of such developments, due to unfore- seen delays in construction, are often serious. The interest on bonds must be met semi-annually or annually from the date of their issue ; hence interest during construction is an important item in the building of any structure or in the cost of development of any industry, and is an item which is particularly uncertain in hazardous construction. In a recent water power development a flood, the most extraordinary that had occurred on the river within the known records, not only caused a loss of approximately $40,000 to the work under construc- tion, but was followed by continuous and unusually high water for the year following, so that not more than ninety working days were avail- able within the year. In the same project, an ice jam in the spring carried out all the trestle and false works, involving a loss of perhaps $10,000 more. These casualties created a delay of more than a year with an extra interest cost of approximately $100,000. From the above it becomes apparent that all estimates should be liberally made, and that if the financial feasibility depends on a very 398 Specifications for Engineering Work limited expenditure, the estimates must be made with the greatest of care. Office engineers who have had little or no experience in the field cannot readily appreciate the contingencies of actual construction. Floods, storms, accidents, unavoidable delays in the receipt of materi- als, scarcity of labor, strikes, etc., have comparatively little meaning in the office but they are very real in the field and will constantly occur and add an unanticipated cost to office estimates. These contingencies are a real part of the cost of the work and just as much a part as the cost of material and labor and consequently must be taken into account in the estimates. Published cost figures are often unreliable or misleading. In the first place the conditions are not sufficiently defined to assure an un- derstanding of what estimate of cost the figures actually include, and they frequently omit general supervision and general and overhead expenses. In the second place such figures are seldom given unless they are comparatively low. If work has cost an excessive amount the cost figures are not a matter for congratulation and are seldom published. Such figures when used must, therefore, be used with dis- cretion and must be substantiated by inquiries made to determine their applicability to the case in hand. Besides the local physical conditions which must be considered in estimating the cost of construction, there are other factors peculiar to each locality that should be considered. In large cities labor is more plentiful but wages are apt to be higher and labor troubles more nu- merous. The cost of materials, wholesale, is not greatly different in the large or small community. Other difficulties due to municipal re- strictions, such as traffic obstruction, etc., are much greater in the large than in the small city. The consequent cost of doing work is therefore frequently greater in the large city, and this is particularly so in regard to subsurface work. Distance from the market for labor and material will also affect the cost. It is frequently difficult to secure and hold labor at points far remote from cities and delays and extra expense result. Accurate estimates can be based only on a somewhat extended practical experience in actual construction work. The young en- gineer should begin at an early date to secure data of the actual cost of the work which he sees performed, and in so doing should take into account the general and overhead expenses which are not as apparent but are no less real than the actual work and material which are placed in the structure or work. Estimates 399 Even personal experience is apt to be misleading. Those who have had experience on difficult and expensive work will overestimate the cost of work where few difficulties or contingencies are involved, and the reverse is equally true and more dangerous to the estimator. The contractor who is used to doing work in large cities can seldom successfully compete with others for work in the smaller cities, and contractors who have been doing work in the smaller places are apt, unless great care is used, to underestimate the cost of work in large cities and to accept losing contracts on account of their lack of apprecia- tion of the much greater cost involved. § 253. Specifications. — The subject matter of which the specifi- cations for architectural work and for engineering structures and plants are to treat should include : A. The materials, supplies and machinery to be furnished. B. The work to be done. C. The methods to be employed in furnishing material or in performing the work. D. The results to be accomplished. In general, the logical arrangement of specifications will call (i) for the description of the work as a whole, and (2) for the de- scription of the same in detail and in the logical order of its con- struction, so far as this can be done, and still complete the detail specification of each part when the description is once begun. In general, the logical arrangement will be. A. General description. B. Foundation or principal features. (a) Acessories or spec- cific details. C. Substructure or secondary features, (a) Accessories or spec- ific details. D. Superstructure or general details, (a) Accessories or specific details. E. Ornamentation and finishing as a whole and in detail. The main subdivisions of any work should also be described in general and in detail. The general description should, in all cases, be sufficient to aft'ord a general knowledge of the work or portion of the work under discussion. The detail specifications should be confined to individual features and, in their description, should be exhaustive. In general, such specifications are made up of specifications for fundamental materials, processes, and for machinery, and all that 400 Specifications for Engineering' Work has been previously stated in regard to those subjects apphes to the complete structures, plants or works of which they constitute the elements. Such specifications may include both general and detailed spec- ifications, and in all cases require a considerable special technical experience and knowledge in their preparation. § 254. Outline. — Preceding the preparation of specifications for complete structures an outline should be prepared including all items which should be covered in the required specification. As these structures are even more complicated and contain a greater amount of detail than the subjects heretofore discussed, such an out- line becomes even more important in order that the specifications when prepared shall include all necessary requirements. The outlines shown in Appendix A will give the idea of such outlines as devel- oped by the author in his professional practice. § 255. Assignments for Preparing Outlines and Specifications for Engineering and Architectural Work. — For the purpose of giv- ing more point and interest to the work of preparing specifications for engineering or architectural works, it is desirable that assignments be based on actual plans for such works. These plans should be in sufficient detail so that the requirements can be clearly distin- guished. For student practice the plans selected should be for sim- ple structures as being more nearly within the capacity of the student. Even such simple structures will be difficult for the beginner, and the complicated subjects often assigned are so entirely beyond their comprehension and ability that they simply result in the unintelli- gent copying of other specifications and little consequent benefit to the student. For purposes of assignment, a number of drawings of simple structures are given in the Appendix C. A few of these drawings are more elaborate and involve a number of parts into which they may be subdivided. In this way, the preparation of a more elaborate specification can be undertaken by several students, and the idea can be made manifest that all elaborate specifications consist simply of a number of more or less simple parts or features joined together in a consistent and complete whole. Besides the drawings of simple works given in the Appendix, there are occasional plans of simple structures published in the tech- nica'l press in form sufficiently complete to afford a fairly satisfac- tory basis for the writing of specifications.

Whenever the word "contractor," or the expression "party of the second part," or "second party" are used it shall be understood to mean the person, persons, co-partnership or corporation who has agreed to perform the work embraced in this contract or to his or their legal representatives. W^henever the word "engineer" is used in this contract it shall be under- stood as referring to the consulting engineer of the party of the first part, or such other engineer, superintendent or inspector as may be authorized by said first party to act in any particular. Whenever the words "directed," "re- quired," "permitted," "designated," "considered necessary," "prescribed," or words of like import are used, it shall be understood that the direction, re- quirement, permission, order, designation or prescription, etc., of the engi- neer is intended; and similarly, the words approval, acceptable, satisfactory, or words of like import shall mean approved by or acceptable or satisfactory to the engineer. Whenever in the specifications or drawings accompanying this agreement, the terms or description of various qualities relative to "finish," "workman- ship," or other qualities of similar kind which cannot from their nature be specifically and clearly described and specified but are necessarily described in general terms to be "satisfactory," "first class," "workmanlike," or in other terms the fulfillment for which must depend on individual judgment, then, in all such cases, any question of the fulfillment of said specifications shall be decided by the consulting engineer, and said work shall be done in accordance with his interpretations of the meaning of the words, terms or clauses defin- ing the character of the work.

Right of Entry. — The party of the first part reserves the right to enter the property or location on which the works herein contracted for are to be constructed or installed by such agent or agents as it may elect for the pur- pose of constructing or installing such collateral works as said first party may desire. Such collateral works will be constructed or installed with as little hindrance or interference as possible with the party of the second part.

If such alterations diminish the quanity of the work to be done, they shall not constitute a claim for damages or anticipated profits on the work that may be dispensed with. If they increase the amount of work, such in- crease shall be paid for according to the quantity actually done, and at the prices established for such work under this contract; provided, however, that if said first party shall make such changes or alterations as shall make useless any work already done or material already furnished or used in said work, that said first party shall recompense said party of the second part for any material or labor so used and for any actual loss occasioned by such change due to actual expenses incurred in preparation for the work as originally planned. No work shall be regarded as extra work unless it is ordered in writing by the engineer and endorsed by superintendent of water works, and with the agreed price for the same specified in said order, provided said price is not otherwise determined by this contract.

Discrepancies and Omissions. — It is further agreed that it is the intent of this contract that all work must be done and all material must be furnished in accordance with the best practice, and in the event of any discrepancies 426 Appendix B between the plans and specifications, or otherwise, or in the event of any doubt as to the meaning of any portion of the contract, specifications or plans, the engineer shall define which is intended to apply to the work, and the con- tractor shall be bound by such decision. Any work or material not herein specified but which may be fairly im- plied as included in the contract, of which the engineer shall be the judge, shall be done or furnished by the contractor without extra charge. Estimated Quantities. — This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and ma- terial to be furnished hereunder. The estimated quantities of the various classes of work to be done and material to be furnished under this contract are approximate and are to be used only as a basis for estimating the prob- able cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and materials to be furnished under this contract may differ somewhat from these estimates, and that the basis for payment under this contract shall be the actual amount of such work done and the material furnished. The contractor agrees that he will make no claim for damages, antici- pated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contained in this agreement. Engineer's Authority: Supervision and Direction of Work. — It is mu- tually agreed between the parties to this contract that the engineer shall su- pervise and direct all work included herein. To prevent disputes and to dis- courage litigation, it is further agreed by and between the parties to this con- tract that if it cannot be otherwise agreed, the engineer shall in all cases de- termine the amount of the quantities of the several kinds of work which is to be paid for under this contract, and he shall determine all questions in rela- tion to said work and the construction thereof, and he shall in all cases de- cide every question which may arise relative to the execution of this contract on the part of said contractor, and his estimate and findings shall be the con- ditions precedent to the right of the parties hereto to arbitration or to any action on the contract and to any rights of the contractor to receive any money under this contract. The engineer shall within a reasonable time render a decision on all claims of the parties hereto and on all questions which may arise relative to the execution of the work or interpretation of the contract, specifications and plans. Lines and Grades. — All lines and grades shall be furnished by the en- gineer but the contractor shall provide stakes and such ordinary labor as may reasonably be required by the engineer to assist him in such work. When ever necessary, work shall be suspended to permit of this work, but such sus- pension will be as brief as practicable and the contractor shall be allowed no extra compensation therefor. The contractor shall give the engineer ample notice of the time and place where the lines and grades will be needed. All stakes, marks, etc., shall be carefully preserved by the contractor and in case of their destruction or removal by him or his employees, such stakes, marks, etc., shall be replaced by the engineer at the contractor's expense. Emergencies. — Whenever in the opinion of the engineer the contractor has not taken sufficient precautions for the safety of the public or the protec- tion of the work to be constructed under this contract, or of adjacent struc- Sample Contract and Specifications 427 tures or property which may be injured by processes of construction on ac count of such neglect, and whenever in the opinion of said engineer an emer- gency shall arise and immediate action shall be considered necessary in order to protect public or private, personal or property interests, and the contractor shall fail to provide immediately the necessary protection after notice by said engineer or without such notice when the emergency makes such a course necessary, the said engineer may provide suitable protection to said interests by causing such work to be done and material to be furnished and placed as shall furnish such protection as said engineer may consider necessary and adequate. The cost and expense of such work and material so furnished shall be borne by said contractor, and if the same shall not be paid on presentation of the bills therefor, then said costs shall be deducted from any accounts due or which may become due said contractor. The failure of the engineer to order the performance of said emergency work shall in no way relieve the contractor from any damages that may re- sult by the omission of said emergency work or protection. Preliminary Approval. — No engineer, superintendent or inspector shall have any power to waive the obligations of this contract for the furnishing by the contractor of good material and of his performing good work as herein de- scribed, and in full accordance with the plans and specifications. No failure or omission of any engineer, superintendent or inspector to condemn any de- fective work or material shall release the contractor from the obligations to at once tear out, remove and properly replace the same at any time upon the discovery of said defective work or material. Right of Engineer to Modify Methods and Equipment. — If at any time the methods or equipment used by the contractor are found to be unsafe or in- adequate for securing the safety of the workmen or other persons who may be endangered thereby, or to secure the quality of work or the rate of prog ress required under this contract, the engineer may order the contractor to increase their safety or improve their character and efficiency, and the con- tractor shall comply with such order. If at any time the wor'king force of the contractor is inadequate for se- curing the progress herein specified the contractor shall, if so ordered, in crease his force or equipment, or both, to such an extent as to give reasonable assurance of compliance with the schedule of progress. The failure of the engineer to make such demands shall not relieve the contractor of his obligations to secure the safety of his men, the quality of the work, and the rate of progress required by his contract. Right to Retain Imperfect Work. — If any part or portion of the work done or material furnished under this contract shall prove defective and not in accordance with the plans and specifications, and if the imperfections jn the same shall not be of sufficient magnitude or importance to warrant removal, or if the removal of such work shall create conditions which are dangerous or undesirable, the engineer shall have the right and authority to retain such work, but shall make such deductions in the final payment therefor as may be just and reasonable. 428 Appendix B Exhibits. — All work shall be done and all materials furnished in strict conformity with the appended Advertisement, marked "Exhibit A," Instruc- tions to Bidders, marked "Exhibit B," Proposal, marked "Exhibit C," Speci- fications, marked "Exhibit D," and • • all of which are hereto attached and are hereby made a part of this contract. Arbitration. — The engineer shall, within a reasonable time, decide all questions or claims of either party to this contract and all matters relating to the execution and progress of the v/ork or the interpretation of the plans, specifications and contract. It is further agreed that in case the engineer renders any decision or gives any direction which in the opinion of either party hereto is not in accord- ance with the meaning and intent of this contract, either party may file with said engineer his written objection to the decision or directions so rendered and by such action may reverse the right to submit the question so raised to arbitration as hereinafter provided. There shall nevertheless be no delay in the execution of the work, and the decision or directions of the engineer so rendered shall be promptly carried out, and any claims arising therefrom shall be thereafter adjusted by arbitration, It is further agreed by both parties hereto that all questions subject to arbitration or adjustment shall be raised and filed with the engineer prior to the execution of the directions of the engineer and that all questions of differ- ence must be raised prior to the final payment on the contract, and that both parties shall lose all right to raise further objection to the engineer's decisions after the final payment has been made. The general procedure shall conform to the laws of the state if necessary, and the decision of the arbiter may be filed in court to carry it into effect. If the engineer fails to make a decision within a reasonable time, an ap- peal to arbitration may be taken, as if his decision had been rendered against the party appealing. In such cases and in case of an appeal from the engi- neer's decision, the demand for arbitration shall be filed with him in writing within ten (10) days thereafter; and in no case later than the time of final payment. The parties may agree upon one arbiter, otherwise there shall be three; one named in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to elect a third v/ithin ten days, he shall be chosen by the presiding official of the Bar Association of Dane county. Should the party demanding arbitration fail to name an arbiter within ten days of the demand, his right to arbitrate shall lapse, and the decision of the engineer shall be final and binding upon him. Should the other party fail to choose an arbiter within ten days, the engineer shall appoint such arbiter. Should either party refuse or neglect to supply the arbiter with any papers or information demanded in writing, the arbiters are empowered by both par- ties to take ex parte proceedings. The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the contract. The decision of the arbiters upon any question subject to arbitration under this contract shall be a condition precedent to any right of legal action. Sample Contract and Specifications 429 The arbiters, if they deem the case demands it, are authorized to award the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal and if the appeal was taken without reasonable cause, damages for any delay occasioned. The ar- biters shall fix their own compensation, unless otherwise provided by agree ment, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be made in writing, and if in writing shall not be open to objection on account of the form of the proceed- ings or award. Prices and Payments. Estimates and Payments. — In order to enable the contractor to prosecute the work to advantage an estimate in writing will be made by the engineer once a month of the amount of work done and ma- terial furnished (and material delivered on the ground and to be used in the completed work), and of the value thereof according to the terms of the con- tract. The first estimate shall be of the amount or quantity in value of the work done since the party of the second part commenced the performance of this contract, and every subsequent estimate except the final one shall be the amount or quantity and value of work done since the last preceding estimate was made. No such estimate or amount or quantity shall be required to be made by strict measurements or with exactness but may be approximate only. Upon the approval of said estimate by the consulting engineer, the party of the first part will pay to the party of the second part 85 per cent of such estimated value, and whenever said contract shall be duly completed, in ac- cordance with the terms herein contained, and when said work and material shall be accepted by the consulting engineer, for said party of the first part, a careful and detailed estimate shall be made of the value of all work and ma- terial furnished under said contract, and the amount due on said work shall be paid to said party of the second part provided however that it is not con- sidered necessary by said first party to retain a certain proportion of same as elsewhere provided for protection against claims for labor and material, for damages, for royalties or otherwise, and excepting also any amount retained as guarantee for the maintenance of the work or material furnished under this contract or for forfeiture Delayed Payment. — In case any payment to the contractor on any esti- mate is delayed by the party of the first part beyond the time provided herein, said first party shall pay the contractor interest on the amount due at the rate of five (5) per cent, per annum for the period of such delay. The term for which said interest shall be paid shall, in the case of progress esti- mates, date from the 10th day after the date of said estimate, to the date of payment of the estimate, — and in case of the final estimate from thirty days after the filing of the certificate of completion and acceptance to the date of final payment of the final estimate. If interest shall become due on any progress estimate, the amount there- of shall be added to the succeeding estimate; and if interest shall become due on the final estimate, it shall be added to such final estimate and paid there- with. The contractor shall not be entitled to interest on any sum or sums which by the terms of this contract the party of the first part may be author- ized to retain. It is hereby agreed that such interest payments, if any, are to be in lieu of any claims of the contractor for alleged damages for breach of contract or otherwise on account of delayed payments. 430 , Appendix B Extra Wo7'k. — If during the performance of this contract the engineer shall order in writing other work done or materials furnished which in his opinion cannot be classified under the unit prices of this contract, the con- tractor shall do and perform such worlt and furnish such material and shall be paid therefor the actual cost plus per cent in addition thereto. The actual cost is hereby defined to include the cost of all labor and materials necessary for the performance of the extra work, including any extra expenses incurred directly on account thereof, also the wages of foremen and the ex- penses attached to contractor's liability insurance covering the labor so em- ployed. No allowance shall be made for overhead charges, general superintend- ence, general expenses, contingencies, or use and depreciation of the construc- tion plant; neither shall said charges include the maintenance of the con- tractor's camp or office, unless such camp or office be maintained primarily on account of such extra work.

Description. — (a) Reservoir. — This structure is to be used for the storage reservoir for the water supply of the city of Madison, Wisconsin, and is to be located adjacent to the present reservoir on East Dayton street be- tween Blair and Blount streets, facing East Dayton street, covering portions of lots 12, 13 and 14 of block 120, according to the plat of this locality. (b) Suction Well. — This structure is to be used for the suction of new and additional high service pumping machinery and is to be located on the block now occupied by the water works pumping station between the station build- ing and Gorham street. 4. Excavation. — The excavation for all structures and foundations shall be carried to the grades indicated on the plans and to lines not more than two (2) feet from the neat exterior lines of the structure. All material excavated, except such as is needed for backfilling, shall re- main the property of the city and shall be hauled and deposited at such points as may be designated by the engineers at the price named in the proposal. 5. Concrete Work. — (a) The concrete shall consist of one (1) part of Portland cement, two (2) parts of fine aggregate, and four (4) parts of coarse aggregate. The proportions of the aggregate shall be based on the volumetric Sample Contract and Specifications 437 measuremeuts in the following manner. One (1) bag of cement, approxi- mately ninety five (95) pounds shall be considered as constituting one (1) cubic foot of cement. The volume of coarse and fine aggregate shall be measured by shoveling into a box or bin without ramming or compacting. (b) Cement. — All cement used in the work heretofore described shall be of the best quality of American Portland cement. It shall be finely ground, thoroughly burned and sufficiently slow setting to permit of working into mortar and using on the work before setting shall begin. Storage. — All cement shall be furnished in well made bags or barrels bear- ing the name, brand, or stamp of the manufacturer, and shall be stored in a storage room or warehouse to be provided by the contractor, and which will fully protect the cement from the weather. Said warehouse shall be provided with a floor so that the cement will be kept from contact with the ground. Delivery. — All cement used in the work shall be delivered at the store- house at least seven (7) days before it shall be used so that sufficient time will be available for its examination and testing. Cement which becomes injured in storage and all rejected cement must be removed within three (3) days after notice to the contractor of its rejec- tion. Tests. — All cement used in the work shall be subject to the latest standard of tests as prescribed and adopted by the American Society of Civil Engineers. Any cement failing to pass any of the requirements above specified may be rejected. (c) Aggregates. — Before delivery at the work, the contractor shall sub- mit to the engineers a fifty pound (50 lb.) sample of each kind of aggregate proposed to be used. These samples will be tested and if found to pass the requirements of the specifications shall be considered as acceptable for the work. Fine Aggregate. — Fine aggregate shall consist of natural sand, or screen- ings from hard, tough durable crushed rock or gravel, consisting of quartzite grains, or other equally hard material graded from fine to coarse with the coarse particles predominating. Fine aggregate, when dry, shall pass a screen having four (4) meshes per linear inch; not more than twenty-five (25) per cent shall pass a sieve having fifty (50) meshes per linear inch, and not more than five (5) per cent, shall pass a sieve having one hundred (lOO) meshes per linear inch. Fine aggregate shall not contain vegetable or other deleterious matter, nor more than three (3) per cent, of clay or loam. Fine aggregate shall be of such quality that mortar composed of one (1) part of Portland cement, and three (3) parts of fine aggregate, by weight, when made into briquettes, shall show a tensile strength at seven (7) and twenty- eight (28) days at least equal to the strength of briquettes composed of one (1) part of the same cement and three (3) parts Standard Ottawa sand by weight. The percentage of water used in making the briquettes of cement and fine ag- gregate shall be such as to produce a mortar of the same consistency as that of the Ottawa sand briquettes of standard consistency. In other respects all briquettes shall be made in accordance with the report of committee on uni- form tests of cement of the American Society of Civil Engineers. Coarse aggregate. — Coarse aggregate shall consist of clean durable crushed rock or gravel graded in size, free from vegetable or other deleterious matter and shall contain no flat or elongated particles. The size of the coarse 438 Appendix B aggregate shall be such as will pass a one (1) inch round opening and shall range from one (1) inch down, not more than five per cent. (5%) passing a screen having four (4) meshes per linear inch. (d) Mixing Concrete. — The materials composing the concrete shall be thoroughly mixed in a concrete "batch" mixer of an approved design and mix- ing shall continue at least one minute after all the materials are in the drum. In any event, mixing shall continue until the various ingredients have been thoroughly and evenly mixed and the mixture shall have a uniform color. The drum shall be completely emptied before the following batch is added. Retempering of mortar or concrete which has partially hardened shall not be permitted. The materials shall be mixed with sufficient water to produce a concrete which when deposited will settle to a flattened mass, but shall not be so wet as to cause a separation of the mortar from the coarse aggregate in handling and depositing. All concrete mixed shall be subject to the inspection and approval of the engineers or inspectors. (e) Placing Concrete. — All concrete shall be conveyed from the mixer and placed in such a manner as to reduce so far as practicable the separation of the ingredients composing the concrete. Suitable bulkheads or bondboxes shall be constructed wherever necessary. All work shall be laid out and car- ried out on lines to insure the greatest strength in the structure. Due con- sideration shall be given to points at which a day's run shall be stopped, and such points shall be subject to the approval of the engineers or inspector. The concrete, except as specifically ordered, shall be sufficiently wet to flow readily and shall be cut down around the steel rods and next the forms with cutting spades and bars of proper size and design for such purpose. Ex- treme care must be taken to see that the concrete is spaded sufficiently to bring the mortar out to the forms and produce a smooth wall surface, and at the same time increase the water tightness of the wall. The concrete in beams, roof slabs and walls shall be laid out in such sec- tions as shall result in the greatest strength and the most satisfactory work, and shall be subject to the approval of the engineers. When concrete is to be laid against a surface of concrete which is already set, said surface shall be carefully and thoroughly cleaned and washed and then carefully and completely covered with a coating of neat cement and wa- ter, laid on evenly with a broom or brush. Said coating of neat cement shall be added just before the new concrete is placed. Noticeable voids or pockets discovered in the concrete when the forms are removed shall be immediately filled with mortar mixed in proportions of one (1) part of Portland cement to two (2) parts of sand. Any cement, mortar or concrete, wholly or partially set before being placed, shall be removed and shall not be used in any portion of the work. No concrete shall be placed in freezing weather or during such times when the temperature will reach as low as 32° F. during the night, unless specifically permitted by the engineers. In case permission is given to place concrete during the cold weather precautions must be taken to house and protect the concrete being placed from freezing. Fires or steam heating shall be used in that case to keep the newly placed concrete from being affected by the frost. Sample Contract and Specifications 439 The aggregate and water shall be heated sufficiently so that when the concrete is poured into the forms or deposited in place it shall be at a temperature not lower than 40 ° F. All concrete work permitted during freezing weather shall be i» accordance with the directions and to the full satisfaction of the en- gineers. (f) Forms. — All necessary forms and false work required shall be pro- vided and erected by the contractor at his own cost and expense, and shall be of suitable design and strength to shape the walls, beams and other parts of the work in the manner shown in the drawings. All forms shall be well braced and strengthened and shall be carefully matched or surfaced in order to prevent leakage of mortar. It is particularly important that the forms be absolutely tight to prevent the leakage of mortar as the loss of mortar will decrease the water tightness of the work. All forms shall be built true to line and grade and shall be sufficiently braced to preserve said line and grade while the concrete is being placed and until such time as the concrete has completely set. In case any form should give way and produce irregular shapes, or leak and produce a faulty structure, said work shall be remedied by the removal of the irregular or faulty portion. The forms shall be built from lumber smoothly dressed on the side next the concrete, and shall be constructed so that the resulting structure shall present a smooth, even and workmanlike appearance. All forms shall be left in place until the concrete has attained sufficient strength to resist accidental injury and permanent stresses that may come upon it. Forms shall be carefully and thoroughly cleaned before being used again, and shall not be used again when warped or injured, without satisfactory re- pairs, (g) Top Finish of Concrete. — The top of the roof and the floors shall be brought to the lines and grades indicated on the plans and due care must be taken with the roof not to permit any hollows or low spots in which the water may collect and stand. The roof shall slope uniformly from the center to the sides as shown on the drawings. The surface of the roof and the floors shall be brought to the proper ele- vation and then carefully rodded and screeded off to a uniform surface, after which the surface shall be smoothed down with a float. The finished con- crete shall be smooth and have an even surface. It is not intended to add a layer of mortar, but it is intended to float the concrete mixture sufficiently to bring the mortar to the surface, (h) Protection of Finished Concrete. — All concrete floors and roofs shall be protected from accidental injury. All freshly poured concrete shall be protected from the heat of the sun by the use of canvas, paper or sand, and shall be thoroughly wet down every twelve (12) hours for at least forty-eight (48) hours after the concrete has been poured. All concrete work shall become sufficiently hard to prevent injury by workmen before walking or passing over it is permitted, 6, Water Proofiing. — It is intended to water proof the side walls of the reservoir from the floor up to elevation 16.5, city datum, and the side walls of the suction well from elevation 8 to elevation 16.5, city datum, with hydrated lime. The hydrated lime shall be added to the cement at the time the cement 440 Appendix B is placed in the mixer. Tlie hydrated lime shall be of an approved brand and shall pass the Standard Specifications for Hydrated Lime of the American So- ciety for Testing Materials. The hydrated lime shall be added in the proportions of one (1) part of hydrated lime to ten (10) parts of Portland cement. The proportions above given shall be by volumetric measurement made by shoveling into a suitable box without packing and care shall be taken to see that the above mentioned proportions are used in every batch. After the forms have been removed the inside face of the reservoir walls and the inside face of the suction v/ell walls shall be given two (2) coats of neat cement wash. The cement shall be mixed with only sufficient water to make a mixture that can be applied with a brush. The cement wash shall be evenly and thoroughly applied so as to fill the pores of the concrete and in- crease the water tightness of the walls. The second coat shall be applied after the first coat has thoroughly dried, 7. Steel Reinforcing Rods. — There shall be built into the concrete at the points shown on the drawings, and as directed by the engineers, round steel rods of the dimensions indicated. The steel for these rods shall have an ul- timate strength of from 55,000 to 63,000 pounds per square inch and shall be of the quality known as medium steel. The rods shall be commercial round steel rods, free from oil, dirt or loose rust, and shall be equal to the best of their class on the market. All rods shall be held to their proper position by clips and wires fastened to the forms. The engineer may increase or decrease the amount of steel reinforcement as in his judgment seems necessary. Addi- tions or deductions in the price paid shall be made for such additions or de- ductions in the amount of reinforcement in accordance with the prices stated therefor in the proposal. The contractor may, if he desires, submit a bid upon twisted or other de- formed bars of medium quality of steel and of equivalent cross section. Due consideration will be given said bid in lieu of the plain round rods as hereto- fore specified. When a continuous line of reinforcement is desired the rods shall be lapped not less than forty-five (45) diameters for plain rods and thirty-five (35) diameters for deformed bars, and shall be securely wired or otherwise fastened together in a manner approved by the engineers. 8. Manholes. — Seven (7) standard cast iron manholes and covers shall be furnished and placed by the contractor at the points indicated on the draw- ings, or as directed by the engineer. The manholes shall each have an open- ing approximately twenty-four inches (24") in diameter, and the covers shall be perforated for the admission of air for ventilating purposes. The cover shall be sufficiently strong to sustain a concentrated load of 300 pounds at the center. The contractor shall furnish and place the manhole frame and cover for the suction well as indicated on the drawings. 9. Gutter. — A gutter constructed of fifteen (15) inch vitrified gutter pipe shall be constructed along one side of the reservoir and for part of the length of the other side as indicated on the drawings. The gutter shall be laid to the line and grade to be given by the engineers. The joints shall be laid with mortar mixed in the proportions of one (1) part Portland cement to two (2) parts of sand of the quality hereinbefore men- Sample Contract and Specifications 441 tioned. A small strip of concrete shall be placed on both sides of the gutter as indicated on the plans, and said concrete shall be mixed in the proportion of one (1 part of Portland cement to two and one-half (2i/{.) parts of sand to five (5) parts of stone or gravel. The gutters shall be connected to the storm water sewer by eight inch (8") vitrified sewer pipe, as indicated on the plans. A suitable cast iron connec- tion shall be provided to connect the gutter to the eight inch (8") sewer pipe and said connections shall be provided with suitable grating with a net water way equal to sixty (60) square inches. 10. Cast Iron Pipe. — The contractor shall furnish and place one (1) twelve foot length of class B thirty-inch (30") cast iron water pipe. Said pipe shall be supplied with a suitable collar or flange at least twelve inches (12") larger in diameter than the outside diameter of the pipe. Said collar shall be either cast as a part of the pipe or shall be so constructed that a lead joint may be poured and calked between the outside of the pipe and the inside face of the collar. The length of pipe shall be carefully aligned and placed to the proper grade and when so placed shall be held rigidly in place during the time the concrete is being poured. The contractor shall furnish and place seven (7) lengths of Class B twenty inch (20") cast iron water pipe. One (1) length shall be furnished with a suitable collar of the type above mentioned. The pipe shall be laid on top of the reservoir floor and at the end it shall have a ninety degree (90°) bend, placed with the outlet turned up. All joints are to be filled with lead and thoroughly calked so as to produce a tight joint. The pipe, after being properly aligned and placed, shall be anchored to the floor of the reservoir by means of three (3) concrete (blocks eighteen inches (18") wide, four feet ( 4' ) long and fifteen inches (15") high. The contractor shall also furnish and place one (1) length of Class B. thirty-inch (30") cast iron water pipe four feet ( 4' ) long with a standard flange faced and drilled A. S. M. E. on one end with a standard bell or hub on the other end. The contractor shall furnish and place) three (3) lengths of Class B twenty- four inch (24") cast iron pipe four feet ( 4' ) long with standard twenty-four inch (24") cast iron pipe four feet ( 4") long with standard flanges, faced and drilled A. S. M. E. on both ends. The three (3) lengths of twenty-four inch (24") and the one (1) length of thirty inch (30") pipe above mentioned are to be furnished with suitable collars as previously described, and the contractor shall place them to the line and grade indicated on the drawings and as outlined by the engineers. Due care must be taken to see that the axis of the pipe is truly horizontal and remains so until the concrete is poured and has thoroughly set. Before leaving the job, the contractor shall cover the ends of the pipes projecting outside the concrete structures by means of board covers securely fastened to the pipes to prevent sand entering the pipes. 11. Shecti7ig and Pumping.~The contractor shall provide all labor and materials necessary to properly sheet around the proposed work so as to ex- cavate to the depth and lines indicated on the plans. Said sheeting shall be carried to such depth as to prevent the sand or other materials from coming into the portion excavated. 442 Appendix B The contractor, at his own cost and expense, shall provide all necessary pumps to properly unwater the site and keep same free of water during such time as the work is under construction. The contractor shall provide all labor and materials to keep the site unwatered during the course of construc- tion and shall provide all necessary bulkheads, drains, etc., to prevent running water from coming in contact with newly placed concrete, or concrete being placed. No concrete shall be placed in water if there is the least possible chance of the materials being separated. Under no circumstances shall the contractor place any concrete in water without the express permission of the engineers. 12. Protection of Present Reservoir. — The concrete in the present reser- voir is of rather poor quality and it is uncertain whether the side walls will be self-sustaining with the earthen embankment removed from the wall on the northeast side. The contractor will be required, at his own cost and ex- pense, to take such necessary precautions to brace the above mentioned wall sufficiently to withstand the pressure of the water when the reservoir is filled to elevation 9.5, city datum. Such bracing may consist of a heavy wale placed against the wall at an elevation of 9.5 with heavy shores placed about sixteen feet ( 16' ) apart. Said shores shall be thoroughly braced and an- chored at the foot to resist the thrust resulting from the water pressure. In any event, the contractor will be required to furnish sufficient bracing of suit- able kind to reinforce the present wall so that the old reservoir may be uti- lized and kept filled with water up to elevation 9.5. 13. Timber Floor. — In case the character of the ground in the bottom of the excavation for either or both the reservoir and the suction well is so soft and yielding that it will be impossible to secure a good job of concrete work for the floors, of which the engineers shall be the judge, then in that case a timber floor shall be constructed by the contractor over the entire area or areas. The contractor shall in that case provide all labor and materials nec- essary to construct said floor or floors. The floor shall consist of one (1) thickness of one inch (1") hemlock matched lumber securely nailed to hemlock stringers two inches (2") by four inches (4") and spaced not more than four feet ( 4' ) apart. The hemlock lumber shall be of such nature that a tight floor will result. The stringers are to be embedded in the earth and the ground leveled off to the top of said stringers. The tops of said stringers are to be placed one inch (1") below the bottom of the concrete floor. Care must be taken to see that the ground is carefully graded off to the top of the stringers so that the timber floor will have a uniform bearing. Second hand lumber may be used in the construction of said floor pro- vided the lumber is of such quality as will make a tight floor. 14. Price and Measurement. (a) Reservoir. — The lump sum price bid for the construction of the concrete reservoir shall include the cost of all labor and materials to properly excavate the site to the lines and grades shown on the drawings; said excavation work shall consist of loading the material into wagons or other means of conveyance but shall not include the cost of handling and depositing same. The lump sum bid shall include all labor, tools and materials necessary to sheet around the site of such portions as may Sample Contract and Specifications 443 require sheeting, and shall include the cost of all pumps, pumping machinery, labor and materials required to properly unwater and keep the site free from water. Said lump sum shall include the cost of all labor, tools, plant machinery, forms and all materials necessary to make and deposit in place the concrete specified and to furnish and add the water proofing materials and shall in- clude the cost of all labor and materials required to add the wash coat of neat cement. Said lump sum shall also include the cost of all labor and materials nec- essary to furnish and place all reinforcing rods, the iron ladder, the cast iron manholes, the cast iron water pipe, the vitrified gutter pipe and the sewer pipe and connections to the storm water sewer. Said lump sum shall also include all necessary bracing of every kind nec- essary to properly reinforce the northeast wall of the existing reservoir dur- ing such time as the nev/ reservoir is being built. It is intended that the lump sum bid shall cover the entire cost of the completed structure except for the item of hauling and depositing the ma- terials excavated and the cost of the timber floor.
