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. Now under construction, the building will, when completed, stand 1,388 ft. tall, replacing the now demolished Union Carbide building.
Due to the constraints of the train terminal below, the tower itself lands on only fourteen points. The columns ‘fan’ and ‘v’ to forgings that weigh more than 75 tons each and sit on 16,000 psi concrete walls cast between MNRR tracks and platforms below. These walls continue down another level to the new Long Island Rail Road East Side Access concourse, almost 100 ft. below street level. Because of the location above a railroad, a concrete core was not possible. In addition, the architectural design dictated that the lobby be completely open, so every single column transfers. At the core, this is accomplished with two 25- ft.-deep transfer girders with 60 in. x 8 in. flanges approximately 300 ft. long. When complete, the steel fabricator will have erected more than 90,000 tons of steel.
Finally, the design had to consider how the steel, some pieces almost 60 tons each, could be erected, knowing that there were active railroad tracks and platforms below and that all of the roadways to the north, south and east of the site are viaducts above the occupied spaces below.
