Weehawken Tunnel and East Portal Shotcrete VECP

New Jersey Transit

Following the framework of a Value Engineering Change Proposal (VECP), Gall Zeidler Consultants provided a shotcrete final lining design to the contractor of this project. The shotcrete final lining was implemented in lieu of a cast-in-place concrete lining within the transition sections between the two-track running tunnels and the station platform tunnel, as well as in the transition section at the East Portal. Notable features of the design included implementation of micro-polypropylene fibers to enhance the fire resistance of the shotcrete final lining (SFL).

Winner of American Shotcrete Association Outstanding Underground Project Award – Value Engineering Change Proposal:

During construction Gall Zeidler Consultants provided quality control for during the final lining installation. In 2009, the design was honored with the Community Service Award for its excellence in construction and renovation of the Hudson-Bergen Light Rail Transit System (HBLRTS).
