Company History

Since its founding in 1947, Flatiron has completed major infrastructure projects across North America.

Named after the unique rock formations found near Boulder, Colorado, Flatiron was founded in 1947 as a materials company. In the 1980s, 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 U.S. in the years that followed. Flatiron opened additional regional offices in California in the 1990s, and has since opened additional offices across the North America. Flatiron now has more than 2,500 employees and has completed projects in every region of the United States and in many Canadian provinces.
