AIT Bridges, a designer and supplier of composite bridge systems & structural components for commercial construction, has added a composite tub girder known as AIT CT Girder to its bridge system offerings. Developed in cooperation with University of Maine’s Advanced Structures and Composites Center, AIT arch bridge system is commercially available since 2010.

This extension of AIT Bridges’ product offerings was created to provide an affordable, long term solution to traditional steel and concrete medium span deck bridges. The AIT CT Girder consists of lightweight fibre reinforced polymer (FRP) tub girders supported on standard foundations with either a precast concrete panel deck or a cast in place concrete bridge deck. Spans up to 100 feet are easily achievable, said AIT Bridges in a press release.

The manufacturing process and installation of the AIT CT Girder brings a significantly reduced carbon footprint over conventional steel and concrete girders. The CT Girder is a 100+ year solution. It is naturally corrosion resistant and it is made of materials that are custom designed to overcome many environmental challenges. It requires little to no maintenance. It is 50 per cent lighter than steel and 75 per cent lighter than concrete girders. This reduction in weight allows for a decrease in large equipment on the construction site and significantly reduces transportation costs.

The CT Girder has the lowest life cycle cost in the industry and many times the lowest initial cost when compared to similar steel and concrete solutions.

“Our composite tub girder is, ultimately, going to be a game changer in the bridge construction sector. It is versatile, strong but light weight, affordable and ultimately intended to replace concrete and steel girders in the marketplace,” said Brit Svoboda, chairman and CEO, AIT Bridges. “For anyone that knows of our arch system, the AIT CT Girder is a natural extension of what we already offer. It can be used as a highway, rail, or pedestrian bridge, even as part of a building structure, parking garage system, marine structure and in many other places where steel and concrete support girders are used. We are pleased to introduce this addition to our line of bridge system offerings.” (PC)
