Who Are We?
The Geotechnical Group is active in the Puget Sound area promoting the professional development of the local geotechnical community. The Group meets monthly between September and May for dinner meetings which include technical presentations by local and international speakers. Dinner meetings are typically the fourth Thursday of each month. The Group also holds an annual Spring Seminar, which features an all-day seminar on a different geotechnical related topic each year. Local and international exhibitors are also present at the seminar, which typically attracts over 300 attendees. A list of past Spring Seminars is shown on this website. The organization also supports local research, student scholarships, and capital improvements at local universities.


  • Highway Rock Excavation By Blasting - Short Course (February 19, 2016) - Portland, Oregon - Sponsored by ASCE Oregon Geotech Group
  • Volunteers  Needed for New Committee

    In response to changes to the building code (IBC 2012 vs. IBC 2008 and ASCE 7-10 vs. ASCE 7-05), recent research regarding the effectiveness of "discrete reinforcement based" ground improvement designs and widely diverging ground improvement designs and design methods, the Seattle Chapter of the Geo-Institute is forming a committee to assess local standards of practice regarding design and construction of discrete ground improvement elements (e.g. compacted aggregate piers, controlled modulus columns, rigid elements, etc.) with the goal of deciding if some form of a ground improvement guidance document is necessary.  The City of Seattle’s DPD has indicated that a guidance document of some form would be helpful in their review of ground improvement design submittals.
    Ideally the proposed committee will consist of consulting geotechnical engineers, ground improvement design engineers, ground improvement contractors, and public officials.  If you are interested in participating in this committee, or would like to be kept appraised of committee developments please contact any member of the Board. This invitation to participate in the planned committee will remain open until the committee is appropriately staffed.

    Please contact Salvati@mcmjac.com and MARohrbach@HaywardBaker.com if you are interested.
