MetFab Metals Constructs Curtainwall Mock-Up of 4 WTC
August 17, 2009
MetFab Metals in Orange, N.J., has completed and passed a mock-up
of a portion of what will be Tower 4 of the World Trade Center (WTC).
The company recently hosted an official viewing of the mock-up,
which was attended by a number of those involved in the construction
team including Larry Silverstein of Silverstein Properties, project
The mock-up stands 50 feet tall and 20 feet wide, and provided members
of the construction, development and design team a chance to view
what the curtainwall will look like. Benson Industries, based in
Portland, Ore., is serving as the contract glazier.
MetFab built the 4 WTC mock-up at its plant, where it also manufactured
the steel mullions, the longest of which is 47 feet and weighs 7,000
Jim Murray, MetFab chief operating officer and general manager,
told USGNN.com that his company got involved when Benson won
the curtainwall installation bid.
"We've been a supplier for them for many years," says
Murray. "For this project we provided the steel support; the
mullions are solid bar stock and the project is bomb-blast resistant."
Murray adds, "One unique challenge of this project was creating
the bars themselves because they are [nearly 50 feet] tall and one
The next step for MetFab Metals, according to Murray, is to begin
procuring materials and scheduling production.
The completed tower will be home to a 47-foot-tall lobby that faces
the National 9/11 Memorial, enclosed by 20 large glass panels. The
full tower, to reach 64 stories total (975 feet), will be wrapped
in 10,000 glass panels and be built with 26,000 tons of structural
steel. It is projected to open in 2012. At press time, specific
information about the glass was not available.
Murray says having the opportunity to be a part of the 4 WTC project
has been memorable.
"This is a significant project because it is part of the WTC
re-build," Murray says. "We're located only ten miles
from Manhattan and we all knew someone there. It's rewarding for
us as a company and personally to be a part of it."
