PIPELINE CONSTRUCTION SERVICES

Comprehensive Pipeline Construction & Excavation Services

With more than half a century of experience in the utility industry, we have handled and perfected ourselves at every aspect of excavation and pipeline installation work. We bring cutting-edge equipment and modern technology to deliver exemplary performance while ensuring complete safety on the site. For a smooth workflow on the site, every large project is broken into manageable lengths, each performed by a specialized team. The various tasks in a pipeline construction project include:

Initial Site Survey
  • Reviewing the environmental features and the proposed pipeline segments.
  • Identifying and marking existing utility lines and agricultural drainages to eliminate accidental damage.
Clearing And Grading
  • Clearing land of vegetation.
  • Installing temporary erosion control measures before starting ground excavation.
Trench Excavation
  • Utilizing backhoes or trenching machines for removing topsoil and laying the pipeline trench.
  • The topsoil removed during the ditching operations is then stockpiled temporarily on the non-working side of the trench.
Pipe Stringing
  • Stringing the individual joints of pipes together, adjacent to the excavated ditch.
  • Bending joints of pipes where the pipeline route direction is changing.
Welding And Coating Of Pipe
  • Aligning and welding the pipe sections together and placing the structure on temporary supports along the edge of the trench.
  • Running a visual inspection of all the welded joints using radiographic inspection techniques.
  • Electronically inspecting the entire pipeline coating to locate and repair any coating faults or voids.
Backfilling The Trench
  • Lowering the assembled pipe structure into the trench using side-boom tractors.
  • Closing the trench using backfilling or bladed equipment.
Testing
  • Hydrostatically testing the pipeline after backfilling the trench.
  • Obtaining test water and disposing it in accordance with the applicable regulations.
Restoration
  • Cleaning up and restoring the site to its original contour, as closely as possible, after the project completion.
