The steel award covers steel to build the Transportation Hub to grade. It includes the Transit Hall, the permanent underpinning of the box for the No. 1 subway line and Hub-related pedestrian connections that link it to the other commercial components of the WTC, according to a release.

Additionally, the steel for the transit hub will form part of the floor of the 9/11 Memorial Plaza, in a design solution reached to put the memorial project back on schedule. Because the PATH Hall roof will comprise the Memorial Plaza's floor, construction of the memorial will be completed two years sooner than estimated, allowing the memorial to open by the 10th anniversary of 9/11, the release states.

In the release, the Port Authority says DCM's bid came in at the cost estimate for the project, notwithstanding an 8% increase in steel prices throughout the region over the past year. Bids on the structural steel work were vetted earlier this month by Phoenix Contractors, a joint venture of Fluor, Slattery Skanska, Granite Construction Northeast and Bovis Lend Lease that serves as the general contractor for the transit hub.
