AECOM Tishman served as CM for this 2.8 million SF, LEED Gold office building. Designed by Rogers Stirk Harbor + Partners, the iconic tower rises to 80 stories and 1,079 feet and is the third tallest building on the World Trade Center site, and the sixth tallest commercial structure in New York City.
The tower is defined by its load-sharing system of diamond-shaped bracing, which helps articulate the building’s east-west configuration and allows all four corners and each floor plate to be column-free, with full-height windows providing unimpeded panoramic views of the city. 3 World Trade Center consists of a reinforced concrete core with steel perimeter. The core is three feet thick on average and is embedded with steel rebar, sheltering emergency stairways, elevator shafts and electrical, communication and plumbing lines. The lobby, with its 64-foot ceiling, looks out onto the 9/11 Memorial Plaza.
The tower was the first construction project in the city to use the European WOLFFKRAN crane, 700B-US model, which was employed given the site’s complicated logistics within the dense urban environment; the crane is able to fit within tight constraints and includes a computer system that allows calibration of swing and boom limits. 3 World Trade is the only building in the world to have a three-sided cable-net wall, which minimizes the need for visible structural elements and lends the annealed glass exterior maximum transparency. In total, the tower consists of 27,000 tons of steel, 145,000 cubic yards of concrete, and 10,000 glass panels.
AECOM Tishman served as CMfor the original World Trade Center and, in addition to 3 World Trade Center, built One World Trade Center, 4 World Trade Center, 7 World Trade Center, the Vehicular Security Center, and, as part of a joint venture, the Transportation Hub.
