D. Andy Vessely
Staff Consultant

Mr. Vessely has 34 years of experience as a Geotechnical Engineer and Engineering Geologist in the Pacific Northwest. He received his Masters degree from U.C. Berkeley under the direction of Profs. H.B. Seed, R. Seed, J. Mitchell and T. Brekke. Mr. Vessely’s areas of interest include earth dams and embankments, earthquake engineering, seismic response analyses, landslide evaluation, geotechnical engineering for water supply and transportation projects, and expert witness services. He manages projects ranging in complexity from dynamic deformation analyses for high-hazard embankment dams subjected to seismic shaking to more routine foundation designs for bridges and tanks. His geologic and engineering training and experience provide him the background necessary to develop cost-effective geotechnical engineering solutions. Representative projects include the following:  

Mr. Vessely is the author of 13 technical papers covering geotechnical aspects of earthquake engineering and landslide evaluation.
