The Kociuszko Bridge (K-Bridge) was built in 1939, intended for 10,000 vehicles per day. In 2015, the daily traffic volume was 179,137 vehicles per day. UrbanTech was retained by the general contractor Skanska-Kiewit JV to provide engineering services for the demolition of the Kosciuszko Bridge approach and main spans.

UrbanTech proposed the multiple demolition schemes, with the project team ultimately deciding to lower the main span onto a barge using jacking tower with jack house and strand jack. During this project, UrbanTech overcame technical challenges including determining dead load in order to calculate correct jacking load, warping effects due to construction equipment and operation tolerances, and second-order effects of jacking tower during jacking operation. The approach truss spans shall be lowered onto a barge with a strand jack lowering sequence procedure.

UrbanTech also provided engineering services related to the demolition of the approach spans of the Brooklyn Connector of the K-Bridge and all the temporary supports required for Replace-in-Place construction of new Brooklyn Connector of the K-Bridge. UrbanTech also prepared MPT and staged construction plans for the Replace-in-Place method.
