World Trade Center Site Stabilization, Reinforcement and Restoration
Ensuring Siructura/ Staiii/iiy
The damage resulting from the destruction of the World Trade Center site requires significant
stabilization to ensure the continued structural integrity of the foundation. In addition, restora
tion of key below-grade infrastructure — both for transportation and other purposes — is required
to prepare the site for future development. Site preparation work includes permanent reinforce
ment of the slurry wall that surrounds the World Trade Center site, demolition of remaining
damaged structures and required excavation.
Creation of New Transforiation Infrasfrucfurefor Vebicu/ar Access
Reconfiguration of the roadways and ramps that were available at the former WTC complex is
necessary to support efficient traffic flow and to meet new security and site-access requirements,
including below-grade access for deliveries. Additional underpinning of the 1/9 subway line.s is
required to allow connections between the east and west sides of the site for construction of the
PATH terminal.
Siti Preparation for iN Memorial anol Future Development
The construction of the World Trade Center memorial is a priority consideration in how infra
structure work will proceed. Construction of the infrastructure improvements will be performed
in conjunction with implementation of the memorial and with Studio Daniel Libeskind's overall
plan for WTC redevelopment.
Restoring Fulton and Greenwich at the WTC site is a crucial component of Studio Daniel
Libeskind’s site plan. (The configuration of streets at the new World Trade Center is discussed
later in this chapter.) Restoration of surface streets on the site, which will require the rebuilding
of underlying structural support elements, are important steps that will improve pedestrian and
vehicular circulation, and reduce traffic congestion at the site and its environs.
The Port Authority, in conjunction with LMDC, is performing planning studies on the various
WTC site infrastructure components described and expects to advance into preliminary engi
neering in mid-2003.
