Officials have ordered evacuations of multiple buildings in Midtown Manhattan after construction workers discovered buckling columns and steel beams on the 21st floor of a high-rise under conversion. Concerns about potential collapse have led to the immediate evacuation of nearby structures, including reports of falling bricks from an East 42nd Street building, prompting road closures. The FDNY is on the scene investigating the situation, as city officials assess the risk posed by the unstable structure, which has resulted in sagging floors and significant safety fears for both workers and nearby residents.
