(A) The laying of pipe on the prepared bedding material shall commence from the lowest point, with the spigot ends pointing in the direction of flow. All pipes shall be laid true to line and grade. They shall be carefully centered so that when laid, they form a sewer with uniform invert.
(B) A pipe plug or bulkhead shall be used whenever pipe-laying operations are not in progress as required to protect the pipe ends from foreign material.
(C) Before making pipe joints, all surfaces of the joints shall be clean and dry. Lubricants, primers and adhesives shall be used in accordance with the manufacturer’s recommendations. The pipe shall then be placed, fitted and adjoined so as to obtain a watertight joint. In the event that previously-laid pipe is disturbed, it shall be removed and relaid.
(D) The contractor shall assure proper alignment and grade by the proper use of lasers, batter boards, surveying instruments or other suitable means.
