With over 30 years of geotechnical engineering experience over a large variety of projects in Oregon and California, our Geotechnical Department specializes in the region’s unique soil, drainage, and seismic conditions. We provide complete geotechnical engineering services to support engineers, architects, contractors, planners and engineering staff of industry and local/state government agencies.

Our services range from feasibility and planning studies, soil and foundation analysis, groundwater control, construction monitoring, to investigations for the assessment of liquefaction.  Quality control is provided at all times through the direct supervision of the Principal Geotechnical Engineer.

As part of a multi-disciplined firm, our geotechnical experts routinely work closely and seamlessly with other professionals to provide cost-effective, buildable designs.  Our capability and expertise consistently brings us clients who seek more than just average experience and knowledge.

Our on staff Geotechnical Engineer is licensed as a Professional Civil Engineer in Oregon and a registered Geotechnical and Professional Engineer in California.

Our soil testing laboratory is equipped to provide a range of classification, strength, expansion, and settlement tests including swell, unconfined compression, consolidation, Expansion Index, Atterberg Limits and gradation, as well as moisture and density. We also have several tools for field sampling work, including a nuclear field density test gauge, proctors, Terzaghi samplers, probes, Corps of Engineers knocker and augers.
