Steps of Construction

Highly skilled crews complete each step during the overall pipeline construction process to ensure safety and quality. Inspectors check work at every step of the process to promote worker safety, environmental performance, and the overall safety and integrity of the pipeline.

  • Step 1: Clearing, Grading and Trenching Before any construction can begin, a survey crew carefully surveys and stakes the construction right-of-way to ensure that only the pre-approved construction work space is cleared.
  • Step 2: Stringing, Welding and Coating Pipeline Segments Natural gas pipelines are assembled in segments typically 40 to 80 feet long. The crew monitors the pipeline design plan to make sure that the segments of pipe are lined up along the pipeline right-of-way.
  • Step 3: Depositing the Pipeline and Backfilling Lowering the welded pipe into the trench demands close coordination and skilled operators. Using a series of side-booms, which are tracked construction equipment, operators simultaneously lift and carefully lower the welded pipe sections into the trench.
  • Step 4: Restoration of the Right of Way The final step in the construction process is to restore the land as closely as possible to its original condition.
