NEW YORK, NY Silverstein Properties Chairman Larry A. Silverstein was joined by approximately 1,000 union construction workers and leading New York government, civic, and business officials at a topping out ceremony marking the completion of concrete construction for the new 3 World Trade Center (3 WTC).

"Today we celebrate New York's construction workers whose dedication and determination have helped us reach this great milestone," said Silverstein. "It also reminds us of how far we have come: 3 WTC will be the newest addition to a neighborhood that has been amazingly transformed and revitalized over the past 15 years."

Janno Lieber, President of World Trade Center Properties, an affiliate of Silverstein Properties said, "Like 4 and 7 World Trade Center before it, 3 WTC is attracting some of the city's most creative and innovative businesses."

Transparent and sustainable design

Designed by award winning British architects, Rogers Stirk Harbour + Partners, 3 World Trade Center is located at 175 Greenwich Street and bounded by Cortlandt Way, Greenwich, Church and Dey Streets.

At 1,079 feet and 80 floors, the 2.5-million-square-foot tower is envisioned to be the third tallest skyscraper on the World Trade Center site - and will be the fifth tallest in New York City, New York, upon completion in 2018.

The tower consists of a reinforced concrete core with steel structure outside the core, and is clad in an external structural steel frame. A defining feature of the building is its load-sharing system of K-shaped bracing, which helps articulate the building's east-west configuration.

Unprecedented MWBE participation

"I couldn't be more proud of the 2,300 union construction workers who have already put in over 5 million hours to build this tower from bedrock to 1,079 feet," said Gary LaBarbera President, Building and Construction Trades Council of Greater New York. "It now stands as part of the skyline of New York as a testament to New York's resolve to never give up, always move forward, and build New York bigger, better and stronger."
