When designers and contractors became unsure of how to lower Brainard Avenue to connect to 130th Street at Torrence Avenue while attempting to eliminate the at-grade crossing, Kapur was brought in to serve as problem solvers for the nearly 32,000 vehicles and 24 trains that pass through the Norfolk Southern main tracks crossing at Torrence Avenue.
The first step was to lower the profile of 130th Street and Torrence Avenue so that they could fit under two new bridges carrying the railway, which Kapur accomplished by providing modeling and visualization services, as well as coordination with contractors, self-propelled mobile transporter providers, and the on-site engineers to accurately model the truss, existing roadways, proposed roadways, and the SPMTs in a 4D environment.
This allowed Kapur to depict the move through time, showing pad build-up, truss movement, and restoration after the move, all while tracking quantities and every piece of equipment.
The plan to move the largest fully assembled truss bridge ever into place was completed without incident or injury. The 400-foot long, 67-foot high, 4.3-million-pound bridge over Torrence Avenue was rolled into place in late August 2012.
This segment of construction was successfully completed on time and on budget in December 2020.
