Alaska Gas Pipeline


The Alaska Gasline Development Corporation (AGDC) is studying a natural gas pipeline designed to deliver natural gas from the North Slope to south-central Alaska where it will provide gas for in-state use and potentially for export as liquified natural gas. The project will ultimately provide a more reliable, cost-effective, long-term energy solution for many Alaskan communities.

AGDC selected Michael Baker to manage preliminary civil and pipeline engineering for the proposed route. For the past four years, we have provided technical support to develop and finalize the Environmental Impact Statement (EIS), in cooperation with the U.S. Army Corps of Engineers (USACE). The final EIS was published in the summer of 2018.

Additional services included:

  • Conducted soil investigations and a temperature monitoring program for soils to accurately model pipeline and thermal interactions. We drilled more than 700 test holes, including holes on river ice and remote holes using helicopter transportable drill rigs.
  • Performed pipeline civil engineering hydrology and hydraulics and environmental analysis and design to support the proposed Pipeline Class 3 Estimate.
  • Developed designs for ancillary features such as pipe ditch, access roads, valve sites, camps and laydown yards and airstrips.
  • Created work plans to establish a hydrostatic testing plan, preliminary pipeline cathodic protection design, pipeline materials specifications, weld specifications, material testing requirements, above ground pipeline design and pipeline stress analysis.
  • Produced interactive, GIS-based project maps accessible via the project’s dedicated website.


“Once built, the Alaska Gas Pipeline will provide much needed benefits to Alaskan residents, including the creation of thousands of jobs during the construction phase of the project and increasing overall energy supply and security.”
