We have successfully estimated, managed and constructed over $200 Million in ground improvement, foundation and shoring projects in Washington, Oregon, Idaho, California, and Hawaii. We service a variety of industries including:

Lake Oswego Pump Station

General Contractor: Slayden
Location: Gladstone, OR



This project was located on the right bank of the Clackamas River in Gladstone, OR. This new 38 MGD river intake pump station supplies water to the cities of Lake Oswego and Tigard. Pacific provided the watertight work area by installing 36” dia. fully cased secant piles embedded into basalt bedrock using a Bauer BG24 drill rig. Drill lengths were approximately 45’ in depth and concrete was tremie placed as sectional casing was extracted.
