The project training program at FT helps students develop an understanding of the construction methodology of large-scale projects. Each student selects a site with national level contractors and studies the construction and related management aspects.

This project, a bridge over the river Ganga in Bihar, establishes a much needed direct link between districts Arrah and Chhapra across the river. It will phenomenally straighten and shorten the route between the two towns, which were otherwise connected by the unnecessarily long route via Patna and the Mahatma Gandhi Setu bridge.

The entire bridge is about 4000 meters in length and is a combination of three different types of construction methodologies. One part, 1790 meters in length, is a ‘simply supported segmental bridge’ having thirty spans. The second, 1920 meters in length, is an ‘extra-dosed balanced-cantilever’ typology with seventeen spans. The third, the remaining 290 meters, is simply supported and is cast in-situ with five spans.

Apart from developing a technical understanding of the construction methodology, the student attempted to  analyse construction productivity, material wastage, design aspects, and management aspects such as safety, quality, billing, labour management.
