Where met- al facings are used on brick walls no extra thickness of brick work shall be re- quired. Section Fifty-eight. Existing Party Walls May Be Used—Walls heretofore built for or used as party walls whose thickness at the time of their erection was in accordance with the requirements of the then existing ordinance. but which may not be in accordance with the require— ments of this ordinance, may be used if in good condition. for the ordinary uses of party walls. provided the height of same be not increased. S’ection Fifty-nine. Height May Be In- creased—In case it is desired to increase the height of existing walls, which walls are less in thickness than the standard re- quired under this ordinance (see sec- tion forty-six), the same shall be done by a lining of brick worklto form a com- bined thickness with the old wall of not less than four inches more than the thick- ness required for a standard wall cor- responding With the total heights of the wall when so increased in height. The 38564 said lining shall be supported on proper foundations. However, no lining shall be less than nine inches in thickness, and all linings shall be laid up in cement mortar and thoroughly anchored to the old brick walls with suitable wrought iron anchors placed two feet apart and prop- erly imbedded into the old walls in rows alternating vertically and horizontally with each other. The old walls must first be cleaned of plaster or other coatings. In place of a brick lining as above, a skeleton steel or iron frame may be erected against said old wall and be properly anchored to same. The strength of said steel or iron frame and its foundations shall be the same as called for in build- ings of skeleton steel construction for walls of similar height, and such steel or iron frame shall be fireproofed as pro- vided» in this ordinance. Where the brick walls of dwellings, erected before the pass- age of this ordinance, are found up- on inspection by the Commissioner of Public Buildings, to be sound and in good condition, and to be capable of sustaining safely an additional story, he may, at his discretion, issue a permit for the erection of such additional story of brick work, even though the walls of the ex— isting building be of less thickness than that required by this ordinance. Section Sixty. Walls not to be Car- ried Up in Advance of Others—No wall or walls of any building, other than a skeleton building, shall be carried up in advance of any other wall of said build- ing, except in the following manner: In all cases where one or more walls are car- ried up in advance 01: other walls of the same building, suitable provisions shall be made to properly bond together and 38565 anchor such walls every four feet in their height by wrought iron tie anchors, not less than one and one—half inches by three—eighths of an [inch in size, and four feet long. All piers shall be anchored to beams or girders on the level of each tier. Section Sixty-one.
