INSTALLATION

1) High-Density Polyethylene (HDPE) Pipe shall be installed in accordance with the instruction of the manufacturer, as shown on the Drawings and as specified herein. A factory qualified to join the technician as designated by the pipe manufacturer shall perform all heat fusion joints.

2) HDPE shall be installed either by Open Trench Construction or Directional Bore Method.

3) Care shall be taken in loading, transporting, and unloading to prevent damage to the pipe. Pipe or fitting shall not be dropped. All pipe or fitting shall be examined before installation, and no piece shall be installed which is found to be defective. Any damage to the pipe shall be repaired as directed by the Engineer. If any defective pipe is discovered after it has been installed, it shall be removed and replaced with a sound pipe in a satisfactory manner by the contractor, at his own expense.

4) Under no circumstances shall the pipe or accessories be dropped into the trench or forced through a directional bore upon "pull-back".

5) Care shall be taken during transportation of the pipe such that it will not be cut, kinked, or otherwise damaged.

6) Ropes, fabric, or rubber protected slings and straps shall be used when handling pipes. Chains, cables, or hooks inserted into the pipe ends shall not be used. Two slings spread apart shall be used for lifting each length of pipe.

7) Pipes shall be stored on level ground, preferably turf or sand, free of sharp objects, which could damage the pipe. The stacking of the polyethylene pipe shall be limited to a height that will not cause excessive deformation of the bottom layers of pipes under anticipated.
