270 Park Avenue

Construction has reached the first office levels of JP Morgan Chase‘s new 1,388-foot supertall headquarters at 270 Park Avenue in Midtown East. Steel assembly on the gargantuan ground floor has reached the eastern end of the rectangular parcel, while the rest of the flaring diagonal columns complete the outline of the base. This week, workers began to weld the first set of vertical columns and diagonal beams above the ground floor, which will become trading floors in the first tier of floor plates in the 2.5-million-square-foot behemoth. Tishman Construction is the general contractor for the project, located between Park and Madison Avenues and 47th and 48th Streets.

Work is progressing on the steel superstructure of 270 Park Avenue, JP Morgan Chase‘s new 1,425-foot supertall headquarters in Midtown, Manhattan. The 2.5-million-square-foot skyscraper is located between Park and Madison Avenues and 47th and 48th Streets and replaces the Union Carbide Building, which is now fully demolished.

Demolition of the Union Carbide Building, JP Morgan Chase‘s former 52-story, 707-foot-tall headquarters at 270 Park Avenue, is now complete as work progresses on its supertall replacement. The remnants of the core and lower levels of the mid-century skyscraper were quickly dismantled and removed since our last update on the Midtown East project just a mere month ago. Meanwhile, on the opposite side of the full-block parcel, steelwork is continuing on the new 2.5 million-square-foot, 1,425-foot-tall tower, which will become one of the tallest structures in New York City. The large rectangular site is 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.

Demolition is nearly complete on the Union Carbide Building, JP Morgan Chase‘s former 52-story, 707-foot-tall headquarters at 270 Park Avenue in Midtown East, while the new steel superstructure for its 2.5 million-square-foot supertall replacement continues to rise on the opposite side of the full-block plot. The new 1,425-foot-tall skyscraper will eventually stand as one of the tallest structures in New York City on a parcel of land 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.
