b. Not be abandoned in place.

3.3.2. Existing Pipe to Remain in Place

Existing pipe that is to remain in place at each manhole shall be thoroughly cleaned prior to connection with flexible rubber coupling and new piping.

3.3.3. Pipe Laying

a. Inspection before Laying: All pipe will be inspected on delivery. Pipe that does not conform to the requirements of this scope of work or is not suitable for use will be rejected and immediately removed from the work site.

b. Preparation of Pipe Ends: All surfaces of the pipe to be joined will be clean and dry.

All necessary lubricants, primer, adhesives, and similar material will be used as recommended by the pipe or joint manufacturer's specifications.

c. Care during Hoisting, Placing, and Pushing Home: Equipment used to handle, lay, and join pipe will be equipped and used as to prevent damage to the pipe. All pipe and fittings will be carefully handled and lowered into the trench. Damaged pipe or jointing material will not be installed.

d. Direction of Work: The laying of pipe will be commenced at the lowest point. The bell or grooved end will be laid upgrade. All pipe will be laid with ends abutting and true to line and grade. They will be carefully centered so that when laid they will form a sewer with a uniform invert.

e. Uniform Pipe Bearing: Special care will be taken to insure that the pipe is solidly and uniformly bedded. For pipe with a bell that is larger than the barrel of the pipe the bedding material will be removed to a depth that will provide continuous support for the bell and barrel. No pipe will be brought into position for joining until the preceding length has been bedded, joined, and secured in place.

f. Alignment and Grade: Each piece of pipe will be checked for vertical and horizontal alignment immediately after being laid. All adjustments to alignment and grade must be made by scraping away or filling in under the barrel of the pipe and not by wedging or blocking up any portion of the pipe or striking the pipe to drive it down.

A curved alignment will be permitted in portion of pipe between SMH #3 (after 45 degree bend) and existing septic tank. Curved alignments will not permitted along any other pipe runs.

g. Backfilling to Secure Pipe: When the joint is made, sufficient backfill material will be simultaneously placed along each side of the pipe to prevent moving the pipe off line and grade. Particular care will be used to prevent disturbance or damage to the pipe and the joints during backfilling.

h. Flotation and Water in the Trench: The Contractor shall take all necessary precautions to prevent flotation of the pipe in the trench. Water shall not be allowed to rise in the trench. The Contractor shall use well points, sump pumps, or another approved method of dewatering as required to lower the water table below the bottom of the excavation while minimizing the migration of fines from the surrounding area. The Contractor shall make a request to the Government and receive approval prior to the use of special dewatering equipment other than well points or sump pumps.

Dewatering operations are considered incidental to the work and no additional compensation will be made to the Contractor.

i. Open Ends: Whenever pipe laying is stopped for any significant length of time, such as at the end of a workday, the unfinished end will be protected from damage and a temporary tight fitting plug or bulkhead will be placed in the exposed ends of the pipe to keep soil or other debris from entering the pipe.

j. Cutting Pipe: Cutting will be in a neat workmanlike manner at right angles to the pipe axis without damage to the pipe. Observe specifications regarding joint locations.

Smooth the cut end by power grinding or filing to remove burrs and sharp edges. Use only tools and methods recommended by the pipe manufacturer.

k. Cleanouts: Cleanouts shall be installed as shown in this scope of work. The cleanout shall be made of compatible material, type, and class and/or strength designation as the pipe and installed as required by this scope of work. The cost for providing and installing the cleanout is incidental to the cost of the pipes.

3.3.4. Pipe Joints

a. General: Pipe will be jointed immediately following the laying of each section. No pipe section shall be left overnight which has not been completely jointed to the preceding pipe section in conformance with this scope of work. The following provisions will apply to insure tight and sound joints:
