PART 3 - EXECUTION 3.1 PREPARATION OF FOUNDATION FOR UNDERGROUND BUILDING DRAINS A. Grade excavation bottoms to provide a smooth, firm, and stable foundation, free from rock, throughout the length of the pipe. Remove unstable, soft, and unsuitable materials at the surface upon which pipes are to be laid and backfill with clean sand or pea gravel to indicated invert elevation. Shape bottom of excavation to fit bottom of pipe for 90-degrees (bottom 1/4 of the circumference). Fill unevenness with tamped sand backfill. At each pipe joint dig bell holes to relieve the bell of the pipe of all loads, and to ensure continuous bearing of the pipe barrel on the foundation. 3.2 PIPE APPLICATIONS - WITHIN BUILDING A. Install hub-and-spigot, service weight, cast-iron soil pipe with lead and oakum caulked joints for larger than 4 inch drainage and vent pipe. B. Install hub-and-spigot, service weight, cast-iron soil pipe with compression gasket joints for larger than 3 inch drainage and vent pipe. C.

Drawings (plans, schematics, and diagrams) indicate the general location and arrangement of the piping systems. Location and arrangement of piping layout take into account many design considerations. So far as practical, install piping as indicated. B. Make changes in direction for drainage and vent piping using appropriate 45 degree wyes, half- wyes, or long sweep quarter, sixth, eighth, or sixteenth bends. Sanitary tees or short quarter bends may be used on vertical stacks of drainage lines where the change in direction of flow is from horizontal to vertical, except use long-turn tees where two fixtures are installed back to back and have a common drain. Straight tees, elbows, and crosses may be used on vent lines. No change in direction of flow greater than 90 degrees shall be made. Where different sizes of drainage pipes and fittings are connected, use proper size, standard increasers and reducers. Reduction of the size of drainage piping in the direction of flow is prohibited. C. Install underground building drains to conform with the plumbing code. Lay underground building drains beginning at low point of systems, true to grades and alignment indicated with unbroken continuity of invert. D. Extend building drain to connect to sewer piping, of size and in location indicated for service entrance to building. 3.5 HANGERS AND SUPPORTS A.

Piping System Test: All sanitary piping and vent systems shall be tested with water or air, in whole or in sections, prior to closing excavations, walls, ceilings, covering with insulation, or otherwise being concealed such that an inspection for leaks would be hindered. The Owner, or his representatives, may require the removal of clean-outs, etc. to ascertain whether or not the pressure has reached all parts of the system. B. Notice: The Contractor shall provide the Architect/Engineer two (2) days written notice prior to commencing testing operations, to allow the opportunity for the Architect/Engineer and/or his representative(s) to observe the testing. The Contractor shall coordinate testing operations with the Architect/Engineer and/or his representative(s). Failure to provide the requisite notice may result in the Contractor, at the Architect/Engineer’s option, being required to repeat the test at no additional cost to the Owner. BICKFORD OF CARMEL, IN 12/12/2012 SANITARY AND VENT SYSTEM 15413-5 C. Water Test: A water test shall be applied to sanitary piping and vent systems either in its entirety or in sections. If the test is applied to the entire system, all openings in the piping shall be tightly closed, except the highest opening, and the system filled to point of overflow. D. If the system is tested in sections, each opening shall be tightly plugged except the highest opening of the section under test, and each section shall be filled with water, but no section shall be tested with less than ten (10) foot head of water. In testing successive sections, at least the upper ten (10) feet of the next preceding section shall be tested, so that no joint or pipe in the building shall have been submitted to a test of less than ten (10) foot head of water. The water shall be kept in the system, or in the portion under test, for at least fifteen (15) minutes before the inspection starts. The piping/system shall not be drained until inspection is complete and has been verified by the Architect/Engineer and/or his representative(s). E. Air Test: An air test shall be applied to sanitary piping and vent systems. An air test shall be made by attaching an air compressor testing apparatus to any suitable opening and, after closing all other inlets and outlets to the system, forcing the air into the system until there is a uniform gauge pressure of five (5) pounds per square inch or sufficient to balance a column of mercury ten (10) inches in height. The pressure shall be held without introduction of any additional air for a period of not less than fifteen (15) minutes. The piping/system shall not be relieved of the pressure until inspection is complete and has been verified by the Architect/Engineer and/or his representative(s). END OF SECTION
