“Not only did Flatiron complete the bridge construction on time, 
their staff went above and beyond normal subcontractor efforts to help
the County succeed in completing the entire project on time and on budget."

- Sean P. Owens, P.E. Douglas County Project Manager

About Us

Flatiron builds heavy civil infrastructure for the transportation, energy and water sectors. We develop innovative solutions to construct large-scale infrastructure, including roads, bridges, tunnels, rail transit and water/wastewater projects, for both public and private clients. Flatiron delivers projects through a variety of contracting methods, including design-build and public-private partnerships.

Named after the unique rock formations found near Boulder, Colo., Flatiron has grown from a small materials company to one of the largest transportation and infrastructure contractors in the nation. This growth began in the late 1980s when the company secured a series of contracts along Interstate 70 through the Glenwood Canyon Corridor, Colorado's most scenic stretch of interstate. Flatiron was recognized for its work on I-70 with awards that catapulted the company into national prominence.

With its reputation secured, Flatiron expanded into new markets in the years that followed. Flatiron opened two regional offices in California in the 1990s, and has since opened additional offices across the U.S. and Canada and completed projects in every region of the United States.

Today, with more than 2,000 employees across North America, Flatiron is consistently ranked in the Top Contractors, the Top Bridge Contractors and the Top Transportation Contractors by leading industry publication Engineering News-Record.
