Flatiron Wins International Award for Innovative Bridge Construction Method

by
Washington Bypass project in North Carolina

The Construction Innovation Forum, an international organization that recognizes construction innovation, presented Flatiron with the prestigious NOVA Award for a new pile driving launching gantry method that reduces the environmental impacts of bridge construction.

Flatiron successfully used the method at the Washington Bypass project in North Carolina to construct a 3-mile-long precast concrete bridge over protected wetlands and the Tar River. The patented process consists of two self-contained gantries capable of performing all the tasks associated with the bridge construction, including precast pile driving, girder erection, and bent cap construction. It is the world’s first application of the pile driving operation from an erection gantry. The method not only saves time and cost, it also eliminates the need for large cranes and temporary access trestles, significantly reducing environmental disturbances to the fragile wetlands below.
