ABOUT OUR FIRM

Qualifications

GeoServices NW, Inc. is a locally owned and operated Pacific Northwest-based geological and geotechnical consulting firm based in Washington and Oregon. We are a dedicated group of geologists and engineers who know local soil, groundwater, and geological conditions typically encountered while building in Oregon and Washington. We are a local, closely managed firm, and take pride in our work and in our competitive professional fees. Our local expertise comes from having lived, attended college, and worked in the Pacific Northwest since the early 1980s.

Our current client list includes Oregon and Washington property owners, contractors, architectural and engineering firms, private developers, attorneys, and regional utility companies. We are well versed in Pacific Northwest building and seismic codes.  We have worked successfully with local, county, and state of Oregon and Washington officials in providing expert commentary and/or expert testimony for solving geological and geotechnical permitting and planning issues.  GeoServices NW has worked extensively as a "contractors geotech" providing geotechnical support and on-site observations services.
GeoServices NW maintains working associaations with local and nationally based engineering and geology based firms and practitioners who extend our technical expertise in the areas of GIS based mapping, hydrogeology, general civic design, etc.

GeoServices NW maintains business infrastructure critical to our offering professional services including providing standard liability and professional liability insurance appropriate to our services provided. We work with expert providers for written reports and logs editing and drafting support so that we can provide professional-looking accurate documentation. We use professional accounting services.

GeoServices NW uses appropriate analytical software for slope stability, shoring, seepage, and drainage analysis. We maintain testing equipment and services for:
  • Soils Laboratory Testing 
  • Slope Inclinometer Monitoring
  • Tilt Meter Monitoring
  • Water Level: Single Reading and Multireading Data Loggers
  • Double Ring Infiltrometer
GeoServices NW, our service area, includes:
  • The southern Oregon coast: Subject to intense Pacific Ocean storms driving erosion and relentless bluff retreat 
  • Coastal Oregon and Washington: Subject to mega earthquakes and tsunamis with unpredictable terrace sand deposits with buried organics and variable groundwater issues
  • Cascade Mountains, which are a string of active volcanoes which create unique combinations of basaltic flows and ash deposits
  • The Columbia River Basin, which contains the largest river system (by volume of flow) in North America, carved the Columbia Gorge. The Portland, Oregon portion is lined by a large levee system and surrounded by deep molasses-like soil deposits subject to liquefaction and subsidence 
  • Southern Washington and Northern Oregon: Remnants of the Missoula catastrophic flood deposits, responsible for much of the landslide activity in southwestern Washington
  • Northern Washington: Glacially affected deposits
  • Oregon and Washington "suspect" terrain consisting of accreted ocean sediments 
Every project we encounter contains at least one of the elements of these soils which present a daily challenge. Our long-time local and detailed knowledge allows us to provide efficient solutions when constructing in these conditions.
