Multiple Offices Complete Simultaneous Project Delivery for Pipeline

Since 2007, Terracon offices have provided services on the $12-billion Keystone and Keystone XL TransCanada pipeline system. This pipeline system will play an important role in linking a secure and growing supply of Canadian crude oil with the largest refinery markets in the U.S. The Keystone Pipeline System will be comprised of the 2,151-mile Keystone Pipeline and the proposed 1,661-mile Keystone Gulf Coast Expansion Project (Keystone XL).

Terracon was originally selected to perform horizontal directionally drilled (HDD) crossing sites in early 2007 for the original Keystone phase. Our performance and quality of field work allowed us to receive additional work and be listed as a qualified subcontractor.

What makes this project unique is the coordinated effort of multiple Terracon offices, including: Lenexa and Wichita, KS; Lincoln, NE; Oklahoma City and Tulsa, OK; Lufkin, Houston, and Conroe, TX; Rapid City, SD; Cedar Rapids and Sioux City, IA; Fort Collins and Denver, CO; Columbia and St. Louis, MO; Boise, ID; and Billings, MT, offices, to complete simultaneous project delivery.

The entire project was managed and coordinated from Terracon’s Lenexa office, providing the client with a single point-of-contact. At each site, Terracon provided QA/QC construction services and geotechnical exploration, analysis, and recommendations for:

  • Design of tank, building, pump, and equipment foundations.
  • Determination of the site stratigraphy and depths to sound bearing soils and/or competent bedrock.
  • Groundwater conditions at the site and the requirements for de-watering (permanent or temporary).
  • Design of access roads, surface drainage, and traffic areas.
  • Soil characteristics with respect to sulphate attack, corrosion potential, and grounding capabilities.
  • Identification of potential sources of borrowed material for construction of trench backfill, road subbase, base and surfacing materials, and tank foundations.
  • Development and recommendations for pile installations at the site including requirements for quality control and inspection.
  • Design considerations and issues for side slopes, drainage, culverts, serviceability, and maintenance that may apply to portions of the site.
  • Determination of extraordinary conditions that would affect design or construction.
  • Determination of local construction preferences, for example, deep vs. shallow foundations.
