PART 3 - EXECUTION

3.1 PIPE INSTALLATION, GENERAL

A. Construct the water system to the lines and grades shown or established in the field.

B. Stake locations of waterlines as shown on the drawings. Waterline location shall be approved by Contracting Officer (CO) before installation of waterline.

C. All water line installation shall be graded to drain.

D. All pipe, fittings, and appurtenances shall be handled and laid in strict conformance to the manufacturer’s recommendations.

E. Drains, valves, and other regulating and controlling devices shall be installed in the line where called for on the drawings.

F. The interior of all pipe, fittings, and other accessories shall be kept as free as possible from dirt and foreign matter at all times. Each piece of line as it is laid shall be cleaned of all debris. When the pipeline has become dirty on the inside during shipment or storage, it shall be swabbed out by drawing a damp swab through the line before lying. Care shall be exercised to keep all joining surfaces clean. Any pipe with contaminated or damaged joining surfaces, which cannot be satisfactorily cleaned or repaired, shall be discarded. Under no circumstances shall pipe be laid in water, and no pipe shall be laid when trench conditions or the weather is unsuitable for such work. At all times when work is not in progress, all open ends of the pipe and fittings shall be securely closed to the satisfaction of the CO so that no trench water, rodents, earth, or other substance will enter the pipe or fittings.

G. Any section of pipe already laid and found to be defective shall be taken up and replaced with new pipe at the Contractor’s expense.

H. A minimum of one-foot separation shall be maintained between electric and water lines in the same trench. Unless the electric conductors are in conduit the water line shall be a minimum of one foot below the electric conductors.

I. Bury piping with depth of cover over top at least 72 inches unless approved by CO.

J. Install underground piping with restrained joints at horizontal and vertical changes in direction. Use restrained-joint piping, thrust blocks, anchors, tie-rods and clamps, and other supports.

3.2 PIPE ALIGNMENT AND GRADE

Complete water system shall be constructed to drain by gravity to pump drains for winter shutdown. Waterlines shall be constructed to drain at a minimum grade of 2%.

Waterlines not meeting this requirement shall be removed by the Contactor and replaced at no cost to the Government.

Pipelines may be relocated slightly, if necessary, to avoid existing obstacles. However, all lines shall be installed to slope towards daylight drains as shown on the drawings.

Deflections from a straight line or grade, as required by vertical curves, horizontal curves, or offsets, shall not exceed the manufacturer's recommended maximum joint deflection or curvature for their pipe. If the alignment requires curvature or deflections in excess of these limitations, the Contractor shall provide special bends, standard fittings, or a sufficient number of shorter lengths of pipe to provide angular deflections at the joints within the limit set forth by the manufacturer.

Bends resulting in tension on joints will not be allowed.

3.3 CUTTING AND HANDLING OF PIPE

Cutting of pipe for closure pieces or for other reasons shall be done in a neat manner by methods, which will not damage the pipe. The pipe and fittings shall be handled in such a manner as to insure delivery and final placement in good, undamaged condition. Particular care shall be exercised not to injure the pipe surfaces or coatings.

Damaged pipe shall not be used in the work.

3.4 LAYING PIPE

No pipe shall be placed in the trench until the CO has approved the trench and bedding.

Each section of the pipe shall rest upon the pipe bed for the full length of its barrel.

Backfill the pipe within 24 hours after installing the pipe in the trench, leaving the joints and one foot of pipe on each side of each joint exposed until testing is complete.

When work is not in progress, securely close open ends of pipe and fittings.

When high density polyethylene pipe is used, it shall be weaved in the trench to provide horizontal slack in the line for expansion and contraction.

High density polyethylene pipe shall be allowed to cool to within 20F of the shaded trench bottom temperature before backfilling.

3.5 INSTALLATION OF CURB STOP

A. Each curb stop shall be housed in a curb box as specified. No pipe shall be placed in the trench until the CO has approved the trench and bedding.

B. Comply with manufacturer’s written instructions.
