Holocene Drilling’s experience includes a wide range of geotechnical, environmental, direct push remediation injection and construction dewatering projects. Our crews and rigs play a key role in most every major infrastructure expansion or improvement project in the Pacific Northwest. We tackle “the tough drilling jobs” associated with the unique geology of the Pacific Northwest and our crews maintain a diverse local presence across all major A&E project types.
WSDOT Brickyard 405 Improvements
Holocene has been supplying Geotechnical mud rotary drilling services to Skanska USA, Inc. since the beginning of the project. Most of our work has been done at night with rigorous traffic control. The I-405/Brickyard to SR 527 Improvement Project enhances four and a half miles of the corridor, primarily in Bothell, from just south of the State Route 522 interchange and ending at the SR 527 interchange.
