The Havemeyer Building, situated at Cortlandt, Dey, and Church Streets, New York City, for business purposes, is an iron-frame building occupying an area over 200x80 feet, and it is provided with a very extensive water supply, drainage, and trap ventilation system for 16 stories, exclusive of roof drains and subbasement. We precede a comprehensive detailed statement of some interesting features of an unusually severe and prolonged pressure test now being executed by the contractors by the accompanying general drawings of the architect, George B. Post. These are of interest as showing the character of the work, its classification and concentration into distinct groups of fixtures and lines, the proportions adopted for the varying services and the development of the system.

Figure 1 is a diagram plan of the basement, and Figs. 2 and 3 are diagram elevations of the riser lines on the main walls, corresponding to the black circles in Fig. 1, which indicate riser pipes. Three of these pipes are here shown in each group, which actually embraces four or five, the additional parallel galvanized-iron pipes for hot and cold water supply being omitted for sake of clearness.
