Laying of Underground Pipes A. General: Place all piping materials in accordance with the following method or procedure. Inspect and clean out all piping carefully before laying. Only material of high quality shall be used. Surface of joints shall be free of cracks or irregularities, which would weaken them, impede the jointing work or cause leakages. Report minor damages to pipes or fittings already incorporated in the works to the Engineer, who will decide if the damage may be repaired or if the pipe or fittings shall be replaced. Repaired items shall be approved by the Engineer. Before jointing the pipes make hollows in the trench bottom to provide sufficient space for the socket and for making the joints. Place pipes in bedrock or rockfill on beds of sand. Provide a flexible joint where a stiff pipe or fitting is built in, e.g. fixed in a wall. Check the compaction of the bed before laying the pipes, so that settlement will be avoided as far as possible. After jointing, support the pipes adequately along their whole length by hard packed fill under their lower quadrant. Pipe bedding shall be compacted to 90% dry density.

Lay pipes to the lines shown on the drawings with a minimum thickness of cover below the finished surface level of 0.8 m over the crown of the pipe, unless otherwise indicated on the drawings. In curves with small radius, use elbow bends. In curves with large radius, pressure pipes of the spigot and socket type may be used, provided that the permissable deflection is not exceeded. The maximum joint deflection shall be in accordance with the Manufacturer's recommendations. B. Trenching, Backfilling & Compaction General 1.01 Description A.

Laying of Underground Pipes A. General: Place all piping materials in accordance with the following method or procedure. Inspect and clean out all piping carefully before laying. Only material of high quality shall be used. Surface of joints shall be free of cracks or irregularities, which would weaken them, impede the jointing work or cause leakages. Report minor damages to pipes or fittings already incorporated in the works to the Engineer, who will decide if the damage may be repaired or if the pipe or fittings shall be replaced. Repaired items shall be approved by the Engineer. Before jointing the pipes make hollows in the trench bottom to provide sufficient space for the socket and for making the joints. Place pipes in bedrock or rockfill on beds of sand. Provide a flexible joint where a stiff pipe or fitting is built in, e.g. fixed in a wall. Check the compaction of the bed before laying the pipes, so that settlement will be avoided as far as possible. After jointing, support the pipes adequately along their whole length by hard packed fill under their lower quadrant. Pipe bedding shall be compacted to 90% dry density.

Lay pipes to the lines shown on the drawings with a minimum thickness of cover below the finished surface level of 0.8 m over the crown of the pipe, unless otherwise indicated on the drawings. In curves with small radius, use elbow bends. In curves with large radius, pressure pipes of the spigot and socket type may be used, provided that the permissable deflection is not exceeded. The maximum joint deflection shall be in accordance with the Manufacturer's recommendations. B. Trenching, Backfilling & Compaction General 1.01 Description A.
