Based in Ashburn, Va., GeoConcepts, A Terracon Company, our DC Metro West office, provides geotechnical engineering, hydrogeologic, environmental services, and materials testing and inspection. GeoConcepts’ experience includes public projects ranging from design-build, roadway, mass transit, and utility infrastructure to facilities serving the federal, educational, institutional, and health care markets.

With offices in Virginia, Maryland, and the District of Columbia, our combined staff looks forward to working together on successful projects throughout the Mid-Atlantic.

This office is supported by Terracon’s Germantown, Md., office established in 2017, and locations in Dulles and Woodbridge, Va., acquired from the former Geotechnical Consulting & Testing in 2016.
