Permasteelisa Bags One WTC Base Cladding Contract
November 16, 2011

The Port Authority of New York and New Jersey (PANYNJ) board approved a new cost-effective architectural design for the exterior cladding system of One World Trade Center, and awarded the contract to Permasteelisa of Windsor, Conn., according to a November 15 PANYNJ release.

The exterior cladding system will cover the 185-foot tall secure base of the tower, and will consist of stainless steel slat panels around the building’s concrete base covered with glass fins. The glass fins will reflect light during the day, provide an aesthetic look at the base of and cover the secure podium structures.

 “Approving this design is a cost-effective solution to a complex problem,” said David Samson, chairman of PANYNJ, in the release. “It provides a practical way to cover the tower’s secure base, and give it an innovative, inviting look for the thousands of workers who will be employed there and the millions of tourists who will visit it.”

This new design is significantly less expensive than the original design, and the PANYNJ board authorized $37.2 million towards project and contract costs.

The base of 1 WTC was originally slated to include prismatic glass, but in May that plan was abandoned. Click here to read the related article in the October issue of USGlass Magazine.

Installation of the redesigned façade system will begin in 2013 and is expected to be completed by the end of that year. The tower is scheduled to be completed by the end of 2013. Work also is under way to install more than 12,000 traditional ultra-clear glass panels to the building’s steel frame.

 “One World Trade Center will be the strongest office building ever built, and the cladding system that has been selected for the base is one of the elements that ensures we will meet that goal,” said Bill Baroni, executive director of PANYNJ, in the release. “Not only will this system be cost-effective, but it will also provide a unique façade benefitting an iconic building.”

Permasteelisa and Skidmore, Owings & Merrill LLP (SOM) in New York, the architectural firm that created the new design for the exterior cladding system, had not returned phone calls at press time.
