Federal Services

Rely on our long-standing federal track record

For 60 years, we’ve partnered with federal agencies to support their unique missions. Our more than 7,000 employees across the United States bring a proven track record of thoroughly understanding agencies’ needs, anticipating potential challenges, and finding innovative solutions to deliver projects that meet the highest standards of excellence.

We value our relationships with each other, both small and large businesses we partner with, and those we’ve come to know at federal agencies from the Department of Defense to the Department of Veterans Affairs (and dozens in between). This means we commit to each other’s safety, serve with integrity, and share in the thrill of a challenge overcome and communities improved.

Proven history of outstanding service

Our deep technical expertise, strong relationships with agency stakeholders, and knowledge of the nuances of federal requirements on more than 20,000 federal projects have helped us understand what it takes to deliver successful projects on time and within budget. We deliver leading geotechnical engineering, materials testing, environmental services, and facilities assessment services to provide mission-critical support while minimizing impacts to operations at federal facilities. With more than 180 offices, one of the nation’s largest drill rig fleets, and experience in all 45 USACE districts, we’re able to mobilize resources quickly and efficiently to meet project needs and deadlines. Every project is enhanced by our comprehensive understanding of federal processes from pursuit through closeout.

Our mentor-protégé joint ventures can help you meet your small business goals

We offer comprehensive environmental services and timely geotechnical exploration services through two joint ventures. The ERG | Terracon JV brings decades of nationwide experience in all facets of environmental services, including natural resources, cultural resources, and NEPA, as well as environmental compliance, cleanup, and remediation services. The Kaskaskia | Terracon JV offers deep experience in delivering a wide range of geotechnical solutions for federal clients including subsurface exploration, lab testing, geophysics, instrumentation, and construction services nationwide.
