Demolition has begun for JP Morgan Chase‘s 52-story former headquarters at 270 Park Avenue, which was once known as the Union Carbide Building. The financial titan is razing the 707-foot-tall mid-century skyscraper to make way for a massive 1,425-foot-tall, 2.5-million-square-foot supertall that will be among the tallest structures in New York City.
Photos by Tectonic show almost the entire Midtown East skyscraper covered in scaffolding and black netting, including the podium section on the western half of the full-block property. The building will be the tallest structure in history to be demolished purposely by its owner, a distinction long held by the Singer Building, which was torn down in 1968 to clear the way for the construction of One Liberty Plaza.
The construction crane on the southern elevation will help dismantle each floor and remove debris along the way. Three platforms on the 16th, 29th, and 41st floors jut out on all four sides from the steel exterior. These help to support the weight of the external scaffolding and ultimately serve to break up the skyscraper and demolition process into four major sections and stages. By now it’s safe to assume that most of the interiors have been stripped to the bare bones of the concrete and steel superstructure, which should allow the edifice to easily come down floor by floor. The repetitive stack of rectangular-shaped floor plates and columns should also accelerate the process.
No timeline has been announced for the full demolition of 270 Park Avenue, though the first half of 2021 seems like a plausible target. Completion of the new headquarters is still several years off. A final rendering and architect of the proposed supertall have also yet to be revealed.
