Pacific Foundation Inc

Pacific Foundation Inc is a Portland-based deep foundations and heavy civil contractor working across marine construction, drilled shafts, pile driving and seismic retrofit throughout the Pacific Northwest. The firm carried the deep foundation and seismic scope on the Oregon State Capitol CAMS programme in Salem, a $598 million rebuild that placed 160 base isolators beneath the 1938 Art Deco statehouse while the Legislature continued to meet in the building above. That work required excavating the basement roughly 20 feet below the original footing line, removing about 36,000 cubic yards of soil, and holding the structure on 2,500 tons of temporary steel shoring through the underpinning sequence. Hoffman Construction held the CM/GC contract and SRG Partnership was architect. Underpinning an occupied historic building is discovery work rather than production work, and it is the narrow specialty Pacific Foundation is built around.

The Capitol underpinning is one job in a much wider geotechnical catalogue, and the catalogue is the point.

Pacific Foundation offers both structural piling and ground improvement, which are different answers to the same question about what a site can carry. Drilled shafts, augercast piles, driven piles and micropiles transfer load down to competent material. Deep cement mixing, jet grouting and rigid inclusions instead treat the soil in place so it can carry more than it otherwise would. Secant and tangent pile walls and soldier pile walls handle the retention side, holding an excavation open while work proceeds below grade.

Offering the full set matters at bid stage, because the cheapest solution for a given site is often the method a specialist does not own equipment for. The fleet here includes Bauer drilling rigs, Klemm micropile rigs and cranes from 25 to 150 tons, backing more than 40 years of geotechnical construction.

Licensing spans nine states — Washington, Oregon, Idaho, Hawaii, Montana, Wyoming, Utah, California and Colorado — under Oregon CCB #196167 and Washington registration PACIFFI883CP, with Texas and Georgia named as expansion markets.

Marine and port work is a distinct strand. Pearl Harbor P-209 and the Norton Terminal development sit alongside the Sand Island wastewater treatment plant and the Synagro biosolids upgrade on the project list, all of which involve driving or drilling into saturated or submerged ground where access is by barge as often as by road.
