Flatiron Constructors wins USD 192 million design-build highway contract in North Carolina

The design-build contract will be executed with Flatiron’s joint venture partner United Contractors (40%), with Earth Tech as the joint venture’s design consulting engineer.  The new four-lane bypass along US Highway 17 will begin south of Price Road and will extend seven miles to reconnect with US 17 just south of Hamilton Beach Road.

The Washington Bypass includes an elevated bridge structure spanning nearly three miles over environmentally sensitive, heavily-wooded wetlands and the Pamlico-Tar River.  Flatiron will utilize a new patent-pending variation of the top-down construction technique.

This span-by-span construction method uses the newly-constructed permanent structure for personnel access and material deliveries. The process includes a self-contained piece of equipment capable of performing all tasks associated with bridge construction, including driving the precast piles, building the bent caps, erecting the 120-foot-long precast girders, and pouring the deck. All of these operations will be performed without the use of temporary access trestles, thus significantly reducing environmental disturbances.

Design and permitting will simultaneously occur over the first year, with construction beginning in February of 2007 and lasting approximately three years.
