Structural Collapse at New York City Construction Site Causes Evacuations and Delays

A significant incident involving the collapse of parts of a building under construction in Manhattan prompted an extensive response by the New York City Fire Department (FDNY). Mayor Zohran Mamdani stated in a news conference that the building remains unstable.

The FDNY reported receiving a call at 7:57 a.m. about falling bricks from a 37-story tower at 235 East 42nd Street. The collapse affected floors 21 through 26, leading to sagging floors and multiple cracks throughout the building. This building, formerly the global headquarters of pharmaceutical giant Pfizer, is currently undergoing a conversion into residential units, according to the city’s Department of Buildings press secretary.

Mayor Mamdani explained that responders have observed further movement in a compromised column. Efforts are underway, involving first responders and structural engineers, to develop plans to stabilize the affected floors. He emphasized the seriousness of the situation.

Authorities have closed Second Avenue, while East 42nd Street is blocked from access. East 43rd Street is also cordoned off as crews work to secure the area. Nearby buildings have been evacuated as a precaution. Fortunately, FDNY confirmed that there have been no injuries reported among workers or civilians.

Cliff Johnson of Steamfitters Local 638, who was present when the incident occurred, mentioned that the general contractor opted for a non-union workforce. Johnson criticized the project’s safety measures, stating that inadequate shoring led to crumbling beams and floors. Construction crews are tasked with gutting the 33-story structure and planning an additional 16 stories.

The collapse and resultant evacuations have led to significant transportation disruptions. School evacuations and street closures have affected local commuters, with buses experiencing delays. Mamdani confirmed no injuries and that all workers have been accounted for.

Investigators from the city were present to assess the situation, advising commuters to avoid the area. Records showed that in 2025, the site accrued seven OATH violations for construction safety, with penalties exceeding $32,000. These violations, including a $10,000 penalty for failing to report an injury-causing incident, have since been resolved.
