Mr. Warren’s unique background as a geotechnical engineer and geologist allows him to provide site-specific geotechnical engineering recommendations based on a strong understanding of local subsurface conditions.  As principal engineer for Applied Geotechnical Engineering and Geologic Consulting LLC (AGEGC), he brings over 20 years of geotechnical and geologic experience to the firm.  The majority of his experience was completed working with Geotechnical Resources Incorporated (GRI) in Portland, Oregon, and The Galli Group in southern Oregon.  Both of these firms are geotechnical-based engineering consulting firms.  Mr. Warren believes in a strong field presence during development of the project design and also during construction.  In this regard, he has provided field investigations, design evaluation and computations, design reports, geologic evaluation, project management, client liaison, engineering supervision and review, and/or construction engineering on over 500 projects in the Pacific Northwest. He has developed excellent field evaluation skills and the ability to complete detailed geologic and geotechnical projects for complicated sites on time and under budget.  His experience includes providing forensic engineering for various projects and clients, including insurance companies and local government agencies.  At the request of various city and county agencies, Mr. Warren provides engineering peer review of various projects.  Mr. Warren has also provided continuing education seminars for architectural firms and a local county agency.
