We are one of the most experienced heavy civil contractors in the country. Our expertise in the heavy civil market includes site preparation, tunnels and underground networks, water and wastewater systems, grading and paving, mining, pipeline development, and mass excavation projects. 

Since 1922 our teams have built many of the nation’s largest, most complex bridge, airport, road, highway, rail, and mass transit projects. Our full-service approach incorporates traditional bid-build project methods as well as other delivery systems.

Our experience as a contractor for the federal government encompasses the building of dams, airports, bridges, roads, and security fences for the Department of Defense, Army Corps of Engineers and Department of Homeland Security.

In addition to our focus on transportation infrastructure, we are leveraging our civil and management capabilities in the power market, partnering with clients, utilities, landowners, environmental agencies, and other contractors on projects such as steam generator structures and installations, hydroelectric dams and solar fields. 

Our vertically integrated construction operations in the West produce aggregates, asphalt, ready-mix concrete, and recycled materials for use on our own projects and for sale to third parties.

Through one of our wholly owned subsidiaries, we work with customers across the country to provide the most versatile and cost effective way to preserve and protect their investment, using such methods as slurry seal, micro-surfacing, sealing and patching, and asphalt paving.
