Thornton Tomasetti is providing structural design services for a 90-story, 2.6-million-square-foot office tower with a 1.3-million-square-foot podium. The structure is part of a 17-million-square-foot mixed-use development consisting of residential, commercial and retail as well as 14-acres of public open space. The site encompasses six city blocks totaling 28 acres.
The building’s location presents a major challenge for this project. A significant portion of the building footprint is situated over the LIRR railyard, which limits the locations for building foundation and support columns because of track locations and clearances. The lower levels of the tower will contain multistory transfer trusses to distribute column loads to the nearest foundation locations. In many locations, these transfer systems will extend into the retail podium, requiring the two buildings to be constructed as one structure.
This tower will rise 1,296 feet and house the city’s highest open-air observation deck, which cantilevers out from the building at 1,100 feet.
