Construction is rising toward the first setback on 270 Park Avenue, the 60-story supertall headquarters for JPMorgan Chase in Midtown East. Designed by Norman Foster of Foster + Partners and developed by Tishman Speyer, the 1,388-foot-tall skyscraper will yield 2.5 million square feet of office space and will set a record as the tallest New York building to be powered by hydroelectric energy. The steel is being fabricated by Banker Steel and assembled on site by NYC Constructors LLC over a giant full-block parcel bound by Park Avenue to the east, Madison Avenue to the west, East 47th Street to the south, and East 48th Street to the north.
The steel superstructure has risen steadily since our last update in early May, and is now only a couple floors below the first setback.
The start of the diamond shaped pattern is becoming more visible, and can be seen from along Park and Madison Avenues. This feature will be present on the eastern and western sides of the supertall between each of the four setbacks. Based on the pace of progress, crews should reach the first setback sometime in the first half of July. It’s possible to see 270 Park Avenue come close to the halfway mark by the end of the year, and perhaps see the superstructure top out before the end of 2023. The speed in construction should increase as the floor plates get smaller after every setback.
A group of new steel trusses has been added to the western half of the base. These white-colored vertical members are positioned near the center by the northern and southern edges of the building’s overall footprint, framing what will become a pair of elevator and egress cores.
Other steel sections within the base are being spray painted white.
Patti & Sons is responsible for fireproofing the steel and is currently working on the first floor above the base, behind the draped white tarps that hang along the perimeter. The black netting and safety cocoon above continue to climb as the tower rises.
270 Park Avenue is slated for completion by 2025.
