The World Trade Center Tower 3 will be constructed across the street from the previous location of the Twin Towers and is expected to be completed in 2017. The building is planned to be 1,155 feet (352m) in height with 80 stories. The four spires in the design will have a total floor space of 2 million square feet (190,000m2). The tower will consist of a reinforced concrete core with steel structure outside the core, and clad in an external structural steel frame. Its safety systems will exceed New York City building code and Port Authority of New York and New Jersey requirements, and it will seek to achieve the LEED Gold standard for energy efficiency.
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.
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 Feb 2011.
Level 64 to Roof due for release 3rd Quarter 2014.
Fabrication for levels 8 thru to 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.
