History
Named after the flatiron rock formations found near Boulder, Colorado, Flatiron was originally a small materials company. In the late 1980s, the company conducted work along Interstate 70 (I-70) through the Glenwood Canyon Corridor in Colorado.

Flatiron opened two regional offices in California in the 1990s. In 1997, Flatiron worked on the first design-build bridge project in Maine, the Sagadahoc Bridge in Bath. In 1998, Flatiron secured a contract for the Eastern Toll Road project. From 1999 to 2004, Flatiron worked on projects in Florida, Texas, Louisiana, and the Carolinas, such as the Carolina Bays Parkway project.

In 2005, Flatiron began working in Western Canada with their first public-private partnership project, the Park Bridge east of Golden, British Columbia. Other projects during the 2000s include the Carquinez Bridge project in 2007, the Port Mann Bridge/Highway 1 project in 2008, the I-35 W Saint Anthony Falls Bridge in 2008, and work in Utah in 2009.

Projects from the 2010s include Circle Drive in 2010, the John James Audubon Bridge over the Mississippi River, sections of the Anthony Henday Drive project in Edmonton, Alberta, the Lake Champlain Bridge connecting New York and Vermont and the Yadkin River Bridges in North Carolina. Flatiron has also worked on several contracts on the new eastern span of the San Francisco–Oakland Bay Bridge. Flatiron has been part of a team that has bid on construction packages for the California High-Speed rail and won a contract that was announced on December 12, 2014.

Dragados/Flatiron/Shimmick submitted a bid of $1.23 billion to design and build the 65-mile stretch from the south end of Fresno to near the Tulare-Kings county line and was deemed the “apparent best value” bidder by the California High-Speed Rail Authority.

As of 2013 Flatiron operated across the U.S. and Canada, with more than 2,000 employees and 12 regional offices. Flatiron also works in heavy civil construction in the northeast via E.E. Cruz and Company. The company is a subsidiary of Flatiron and Turner Construction.
