Portfolio
Atkinson's history dates back to 1926, when projects such as the Bonneville and Grand Coulee dams led the way for the development and expansion of the western United States. With over 75 years of experience, Atkinson has constructed over $40 billion worth of projects, and has grown to be one of the most well-respected heavy civil contractors in the world.
Atkinson offers a comprehensive range of project development and construction services to clients in the power, industrial, commercial, mining, tunneling and infrastructure markets. Our portfolio includes hydroelectric power, bridges, highways, dams, railroads, tunnels, shafts and underground mining projects. In addition, Atkinson enhances Clark's capabilities in building construction, working together on such projects as commercial, industrial, institutional, research and development laboratories and microchip facilities. Following are some of Atkinson's current and recent projects.
