At Vector Engineering we pride ourselves with being a multi-disciplinary civil engineering firm. Our firm has roots tied to Olympia, Washington and was established by owner Ben Cook in 2001. Vector remained open & held strong through the recession, moving our main office to Tumwater, WA and then expanding shortly after to Elma in 2014. As our work spread toward the Washington coast an additonal Vector office was essential for the company to service Grays Harbor County and beyond. Our tight knit team is dedicated & comfortable with collaborating with other firms & our client’s project managers to optimize our clients projects.  


Vector Engineering clients range from homeowners to municipalities and public districts to National Defense facilities. Vectors team have extensive history with bridge and Tribal projects on the Olympic Peninsula, Quinault Tribal Lands and with the BIA and other government entities. Our work is roughly 60% public work consisting of governmental, tribal municipal and district type clients (fire and school districts) 


Located close to the I5 corridor our team of engineers are easily mobilized to site visits & project meetings.
