Before construction begins, PEG surveyors will stake the centerline of the pipeline route, the exterior of the right-of-way and temporary workspace, road crossings, and property corners that are located in the project corridor. We ask that you do not disturb these stakes as many will be referenced for the duration of construction.

The pipeline right of way is cleared of vegetation. Temporary erosion control measures are installed prior to any earth-moving activities.

PEG uses backhoes and trenching machines to excavate the trench. The soil that is excavated during ditching operations is temporarily stockpiled on the right-of-way.

Individual joints of pipe are strung along the right of way adjacent to the excavated ditch and arranged so they are accessible to construction personnel. A mechanical pipe-bending machine bends individual joints of pipe to the desired angle at locations where there are significant changes in the natural ground contours or where the pipeline route changes direction.

After the stringing and bending are complete, the pipe sections are aligned, welded together, and placed on temporary supports along the edge of the trench. Welds along the pipeline route are then x-rayed. Line pipe requires a coating at the welded joints. The entire pipe coating is then inspected.

The pipe assembly is lowered into the trench by sideboom tractors. The trench is backfilled. No foreign materials are allowed in the trench.

After backfilling, the pipe is filled with water and pressure tested. Tested water is obtained and disposed of in accordance with applicable regulations.

PEG will then clean up and restore the work area, as soon as possible. Disturbed areas are restored, as nearly as possible, to their original contours. Temporary environmental control measures are maintained until the area is restored, as close as possible, to its original condition.
