World Trade Center Tower 3

CLIENT: Owen Steel Company
LOCATION: New York City, NY
COMPLETION DATE: 2011-2016
project overview:

The World Trade Center Tower 3 was constructed across the street from the previous location of the Twin Towers. The building is 1,155 feet (352m) in height with 80 stories and the four spires in the design have a total floor space of 2 million square feet. The tower consists of a reinforced concrete core with steel structure outside the core, and clad in an external structural steel frame. Its safety systems exceed New York City building code and Port Authority of New York and New Jersey requirements.

DBM Vircon’s Scope of Work:

DBM Vircon’s scope of work included the 3D BIM modeling and shop detailing of the structural steel on the following areas:

  • Structural steel framing of 80 levels including underground retail, concourse, office areas & roof;
  • Structural steel column (boxed, WF and plated), beams, girders, trusses and braces from 1st floor through roof parapet and mast;
  • Review & model control of anticipated elastic shortening of the structure;
  • Switch gear room, mechanical room and building spot network roof framing;
  • Tank support, window washing track, cooling tower, screen wall frames;
  • Elevator tie down beams;
  • Slab/Deck support angle and plates, kicker, outriggers, braces and hanger angles.

World Trade Center Tower 3 Project Highlights & Challenges:

  • The 3 World Trade Center is a high profile 80-level retail and office tower located on the ground zero site, across the road from the original Twin Towers that were destroyed during the September 11 attack
  • Detailing and engineering were released up to the level 63 and fabrication up to level 7 in February 2011
  • Level 64 to roof due for release 3rd quarter 2014
  • Fabrication for levels 8 through to the roof have been released for fabrication July 2014
  • This has been a challenging project due to the high number of design changes, RFI’s and CDQ’s
  • The steel fabrication was to be done by two different fabricators that wanted the drawings and reports to reflect their own fabrication preferences
