A.
Laying pipe.
The ends of the pipe shall be cleaned before the pipe is placed. The pipe shall be laid on a prepared foundation starting at the outlet end with the spigot ends pointed in the direction of the flow and shall continue toward the inlet end with the adjoining sections matched properly. The pipe shall be laid true to the lines and grades indicated on the plans. The mouth of the pipe shall be protected to prevent earth and bedding material from entering the pipe as each section is laid. The pipe shall be matched and fitted to form a smooth, uniform conduit when placed in the bed. The trench bottom shall be shaped and the excavation shall be performed as specified under Section 02222 “Excavation, Trenching and Backfilling for Utilities”. No pipe shall be laid on unsuitable soft material, under any circumstances. Proper facilities are to be provided for hoisting and lowering the pipe sections into the trench without disturbing the prepared trench bottom or sides. The Contractor shall be responsible for dewatering of the trenches and the diversion of drainage during construction. Any pipe section that is laid and found to be defective or damaged shall be taken up and replaced or relaid at the cost of the Contractor.
