Project Highlights
  • 36 miles of various diameter pipe ranging from 26-inch OD to 4.25-inch OD with pipe wall thicknesses ranging from 0.250 inch WT to 1.00 inch WT
  • Concurrent installation of multiple lines – as many as seven lines in a single trench with a bottom width of 20 feet; required using a crane for pipe installation
  • Limited access to ROW
  • Remote location with challenging terrain
  • All valley work required 100 percent matting of ROW
  • Extensive dewatering required for valley work – design, installation and operation of a sock drain system
  • Fast-track schedule and startup
  • Multiple creek and road crossings.  Creek crossing were through very unstable soil conditions – excavations were shored with two types of engineered shoring systems
  • Worked around and next to multiple existing pipelines and utilities

Project Details

Barnard Pipeline’s work on ExxonMobil’s Piceance Development Project outside of Rifle, Colorado, entailed concurrent work on numerous high-pressure gas pipelines across varied terrain. The project included installing gathered gas lines; combined liquid lines; clean condensate lines; raw water line; water disposal and distribution lines; and fiber optic and electrical cables. Concrete-coating, fusion-bonded epoxy coating of welds, hydro-excavation, structural concrete and hydrostatic testing were other activities associated with completing the work. The project encompassed pipe fabrication of several facilities, including above-ground flanged connections, valve sets, and various pig launcher and receiver locations. Located in a remote region of northwestern Colorado, the right-of-way on this job ranged from steep mountainous terrain to relatively flat creek valley with high groundwater.  The project was so remote that all office communication was conducted via satellite.  Due to local road restrictions, all employees were bused to the work site. At peak construction, 391 employees worked on the project. Other challenges included working around and next to numerous existing gas pipelines in the area, including several miles of parallel construction.  Extensive coordination with existing pipeline owners and operators was required.  Barnard Pipeline completed the project with zero reportable environmental releases or events and with a weld repair rate of less than 1 percent.
