Barnard Wins ENR Southwest Best Project Award Building a Reputation Up North

Our expansion into has led to challenging new projects and the opportunity Environment category and is a finalist for the ENR Southwest Project of the Year. Barnard’s 2020 to grow our team with talented professionals. In early 2019, Mike Westgate joined Barnard This innovative project involved Barnard constructing a 525-foot-deep access as Vice President of Business Development in Canada. With over 15 years of experience, shaft and underground forebay to allow for construction of 34 well shafts housing ENR Rankings Mike has managed, pursued, and delivered civil projects across Canada, and has become an submersible pumps that will deliver the surrounding area with much needed water industry leader in public-private partnerships (PPP).

Barnard Continues Multi-Year Strategic Partnership with PG&E Barnard is currently in our seventh year of participating in Pacific Gas and Electric Company’s (PG&E’s) Gas Transmission Strategic Partnership. This partnership is dedicated to strengthening and improving the integrity and safety of PG&E’s natural gas transmission system. Since 2013, Barnard has completed more than 350 projects spanning from the Mojave Desert to the California-Oregon border. We have several ongoing projects in the Northern California region, including replacing pipelines using direct-burial and horizontal directional drilling methods, installing new piping on hangers beneath a bridge, drilling deep well anodes, and installing gas-powered generators.
