Construction is climbing higher on JPMorgan Chase‘s 1,388-foot supertall headquarters at 270 Park Avenue in Midtown East. Designed by Lord Norman Foster of Foster + Partners with Adamsom Associates as the architect of record and developed by Tishman Speyer, the 60-story skyscraper will yield 2.5 million square feet of office space with a capacity of 15,000 employees, and will become the tallest structure in New York completely powered by hydroelectric energy. JB&B is the MEP engineer and AECOM Tishman is the general contractor for the full-block property, which is bound by East 48th Street to the north, East 47th Street to the south, Park Avenue to the east, and Madison Avenue to the west.
Crews have assembled more office levels of the steel superstructure since our last update in early May, when construction had just reached the top of the second and tallest section in 270 Park Avenue’s five-tiered massing. A tower crane has been disassembled since springtime, leaving just two remaining in service. Recent photos show progress hovering around the 45th floor, which is roughly the midway point of the third tier. Crews will soon reach the 300-meter (984-foot) supertall mark before transitioning to the final two tiers, which have some of the tallest ceiling spans of the remaining 15 levels. Many of these final stories will be reserved for mechanical space. Based on the pace of progress and the reduced size of the upper floor plates, topping out could likely happen before the end of the year.
Installation of the tripled-glazed windows and metallic bronze paneling has also made significant progress across the bottom office floors since our last update.
A section of open slits in the curtain wall indicate the location of a mechanical level.
Directly below the first office floor is a honeycomb grid of metal cylinders surrounding the top of the inverted trapezoidal base. Most of this can be seen on the eastern half of the base.
Below this, the lobby will be enclosed with expansive sections of glass with a thin metal framework, some of which has been installed facing Park Avenue. The glass will span between the steel columns fanning diagonally outward from the eight massive steel nodes at ground level.
The below rendering is oriented north along Park Avenue and previews the finished look of the various elements of the base.
Other team members of the project include Banker Steel providing the steelwork, NYC Constructors serving as the steel subcontractor, Mueser Rutledge Consulting Engineers (MRCE), which designed the structural foundation elements, Severud Associates as the engineer of record, R&R Scaffolding Ltd. as the provider of the BMU, and New Hudson Façades supplying the curtain wall.
270 Park Avenue is anticipated to be completed sometime in 2025.
