Construction crews excavating a vacant lot in Brooklyn, N.Y., were on the job Nov. 11 when the three-story building next door collapsed, resulting in fatalities and injuries, city officials said.
The cause is under investigation. The collapsed building, at 1321 Flatbush Ave., had apartments over ground-floor commercial space, and much of its debris landed in the construction pit, where New York City Buildings Commissioner Ahmed Tigani said crews were digging for a planned new building.
The neighboring site has a recent enforcement history. In April, the city's Department of Buildings (DOB) cited a demolition contractor there after inspectors found an entire building had been torn down despite an order to halt all demolition. DOB records show the Class 1 violation, issued April 23, carried a $10,000 penalty, which has been paid. The violation is now listed as resolved, and the notice does not state why the work stoppage was ordered. In an email to CBS News New York, the contractor pointed to a missing fire extinguisher and housekeeping issues and said it handled only the demolition months ago, not the digging under way Nov. 11.
City zoning records show the developer of the lot, at 2625 Bedford Ave., is seeking to build nine stories with 64 residential units and a first-floor grocery store, CBS News New York reported. Tigani said a three-story building has been approved for the site, but the nine-story plans have not.
Three firefighters were among those hurt, according to New York City Mayor Zohran Mamdani. About 250 firefighters worked the scene, the mayor said, using pickaxes, power saws and search dogs to reach people who may still be trapped. Fire Department of New York Commissioner Lillian Bonsignore described the rescue work as dangerous.
The DOB's investigation is ongoing, and it remains unclear whether the construction work played any role in the collapse. AP reported that it left messages seeking comment with the project's architect, general contractor and property owner, as named in city records.
