5 World Trade Center
Located on the southernmost portion of the World Trade Center (WTC) site, 5 World Trade Center will be developed by the Port Authority of New York and New Jersey. In September 2006, as part of the Master Redevelopment Agreement for the World Trade Center site, the Port Authority assumed responsibility for construction of this tower.
Designed by the architectural firm of Kohn Pederson Fox, it
will stand on the site currently occupied by the remains of the Deutsche Bank
building, which was irreparably damaged by the terrorist attacks of September
11, 2001. The 40-story building's decontamination process began in
early 2006, when crews from Bovis Lend Lease erected scaffolding and elevator
hoists and installed new netting around the exterior. Interior abatement
followed, and included environmental cleaning and removal of all interior
surfaces and non-structural elements in the building.
The actual floor-by-floor deconstruction commenced in March
2007, but was suspended after a fire on August 18, 2007 that damaged floors 13
through 18. At the time, the building had been deconstructed to the 26th floor;
the search for potential human remains in the building concluded in early June
The tower was deemed structurally sound immediately after
the fire, and soon the project managers instituted several safety improvements.
They included repairing the fire standpipe, using fire-resistant materials and
equipment, rebuilding safety structures, centralizing the negative-air-pressure
and electric controls, and improving emergency access and egress points.
The city’s stop-work order was lifted at 130 Liberty Street in April 2008, and
decontamination resumed in May 2008 with constant fire department and
environmental oversight and monitoring. Crews wrapped up abatement in September
2009, with deconstruction resumed in November 2009.
