GEO Consultants Northwest (GCN) supports it's clients  with a complete range of environmental site assessments to geotechnical  investigations, analysis, design, construction observation, remediation  services, industrial hygiene services, litigation support, stormwater  services and laboratory testing capability.  Our staff of geotechnical  engineers and geologists has experience performing geotechnical  investigations and designs for projects throughout the Pacific  Northwest, and many regions in the nation.  


GCN has been  retained as a consultant for hundreds of projects, including commercial  and industrial facilities, highways, rail roads, bridges, deep  foundation design, landslides and slope stability, and housing.  We have  staff experience with seismic evaluation, dams, excavations,  dewatering, geotechnical instrumentation and monitoring, slope  stability, and slope restoration. With the addition of David Rankin, GCN  can provide quality environmental services to Oregon and Washington.   Mr. Rankin has been retained as an environmental site assessment  provider for over 1,500 sites (including over 100 multi-parcel  portfolios), remedial investigations,feasibility studies, and compliance  groundwater monitoring.


Working from a small main office in  Portland, our staff generally telecommutes.  This approach optimizes our  flexibility and cost structure. 


GCN is committed to a teaming  approach that provides broad support from due-diligence and feasibility  studies throughout design and construction, as well as forensic damages  and operations/maintenance.
