After eight years of design and construction, One Vanderbilt has become Midtown Manhattan’s tallest office tower at a height of 1,401 ft. Planning for the building started in 2013 and the tower opened in September 2020 with a $3.3 billion building offering 1.7 million sq. ft. of office, retail, and amenity spaces and $220 million of transit and open space improvements directly adjacent to Grand Central Terminal.
One Vanderbilt employed a steel-first erection sequence developed and refined by Severud Associates in which framing at the core was designed to stand alone for 12 stories. As erection proceeded, concrete shear walls followed the steel below, using a self-climbing form system and hand-set forms. Column transfer systems at the 5th and 12th Floors required floor-deep trusses. At truss nodes, forgings were utilized to make connections as compact as possible while also providing a smooth flow of forces and simplifying field work.
Supported by a concrete mat more than nine ft. thick, the core is augmented by steel outrigger trusses at three intermediate levels that were coordinated closely with the MEP consultant to minimize interference with the building’s advanced mechanical systems. A steel tuned-mass damper keeps accelerations within a comfortable range for building occupants.
Taking advantage of changes to zoning laws, the new JP Morgan Chase Headquarters, also known as 270 Park, is the first of several projects aiming to change the skyline north of Grand Central Station. Located at 270 Park Avenue, the building encompasses a full city block bordered by 47th and 48th Streets and Madison and Park Avenues.
