3 World Trade Center steel frame tops off
A topping off ceremony was held in New York City yesterday (October 6th, 2016) to mark the completion of 3 World Trade Center's 80-story, 1,079 foot tall steel frame. During the ceremony, the frame's final steel beam was lifted into place at the tower's summit.
3 World Trade Center's glass curtain wall has nearly reached the top floor. Vidaris is providing comprehensive building envelope consulting and monitoring services for the curtain wall's construction. The curtain wall includes a high-performance thermally-broken window wall system which incorporates low-emmisivity glass for optimal thermal performance. 3 World Trade Center is targeting LEED Gold efficiency certification.
The 2.5 million square foot 3 World Trade Center will contain Class A office space with 150,000 square feet of retail across the tower's first five floors. 3 World Trade Center is the fourth of five buildings that will be built at the World Trade Center site.
