While PGI has large project experience, we also build smaller projects for our midstream and shale based clients. PGI is experienced with…

  • Marginal sized projects
  • Urban construction techniques
  • Smaller diameter piping systems
  • Existing, in service operating systems
  • Re-testing, pipeline replacements, repairs and upgrades


Completed Projects List

Featured Pipeline Project in Lower 48

PGI successfully completed the construction of 20.4 Miles of 36” Natural Gas Pipeline in Ritchie, Calhoun, and Wirt Counties, WV.  Construction included the installation of 36” pipe through 72 Streams, bored 4 roads and highways, 1 – 1,475’ horizontal directional drill of the South Fork of Hughes River, 1 – 1,227’ direct pipe installation of the Little Kanawha River.   The terrain crossed on this project consisted of 50% rock excavation completed by both blasting and mechanical means and steep slopes construction techniques requiring winch support for pipe installation.  Approximately 38 hills or 16% of the project consisted of steep slope construction.

Featured Project in Alaska

Price Gregory International, mobilized equipment and personnel to provide construction and fabrication for the replacement of the 14-mile long 30-inch seawater line from CW-01 in Kuparuk to the Oliktok STP. The existing 30-inch seawater line was decommissioned and the new insulated steel pipe was installed on existing pipe racks adjacent to the old line. PGI tied the new pipeline in to the existing Sea Water Treatment Plant (STP) at Oliktok Point. Approximately 1,950 feet of the pipeline was buried in the frozen gravel fill of the Oliktok Point Causeway.

PGI crews accomplished this task while living in a remote man camp located within the Kuparuk Oilfield. Winter North Slope conditions prevailed throughout the project with temperatures dipping as low as -50o F.

The construction was broken into 5 distinct scope elements:

  • Ice Road Construction and Maintenance
  • Underground Civil Pad, Road and Caribou crossings
  • Installation of new Vertical Support Members
  • Installation of a 14-mile long new insulated and coated pipeline.
  • Hydrostatic Line Testing

Project was completed on time within one winter construction season. Tie ins were accomplished during the summer as part of planned facility shut downs.
