Excavation Near Site May Have Triggered Brooklyn Collapse
At least eight people died when a three-story building at 1321 Flatbush Avenue fell, and engineers are reviewing whether deep digging on the adjacent lot destabilized the foundation.

A three-story apartment building at 1321 Flatbush Avenue in Brooklyn collapsed Wednesday afternoon, killing at least eight people and leaving crews searching for survivors in the rubble. The incident occurred near an active construction site, prompting questions about whether nearby excavation work contributed to the failure of the structure.
City records indicate the building contained four residential units above a ground-floor commercial space. Emergency personnel received the initial call at 4:01 p.m. EST. Approximately 250 firefighters and other responders were dispatched to the scene immediately after the alarm.
Mehrdad Sasani, a professor of civil and environmental engineering at Northeastern University, stated that excavation crews may have dug too deeply near the building without adequate support. He noted that standard practice involves installing vertical piles, horizontal beams, and diagonal steel braces to stabilize soil. Sasani said he suspects the contractors did not provide proper support for the soil beneath the building's foundation.
Excavation on the adjacent empty lot at 2625 Bedford Avenue began within 30 days of a June 10 letter from the parcel owner to neighboring landlords. The letter promised precautions would be taken to protect adjacent properties. An anonymous complaint filed with the New York City Department of Buildings after the collapse alleged that a subcontractor excavated too much area along the neighboring foundation at once. The complainant wrote that the failure might have been preventable.
Mayor Zohran Mamdani addressed reporters Wednesday, describing the event as a devastating collapse that affects many New Yorkers. He urged residents to stay clear of the area while rescue operations continued. The city's building department and law enforcement partners are leading the investigation into the cause of the collapse.
Daniel Aldrich, director of the Resilience Studies Program at Northeastern University, noted that immigrant families in the area may have weaker connections to government institutions. He recommended the city establish family assistance centers with Spanish language translators. Aldrich also suggested the city set aside funding for residents who lost homes and belongings without renters insurance. He identified Bethesda Church of God across the street as a gathering place for affected residents.
The Flatbush neighborhood includes sizable Haitian, Jamaican, and Trinidadian communities. Rescue efforts remained active as of Thursday morning, with officials continuing to search the debris for survivors.
