Excavation work at a construction site next door to a Brooklyn building that crumbled suddenly — killing eight people and injuring nearly 20 others — is being eyed as a possible cause of the devastating collapse.
asserted
that → crumble → collapse
The three-story Flatbush apartment building caved into the adjacent lot Wednesday afternoon as the excavation work was underway — prompting Mayor Zohran Mamdani to order a review of about 100 properties across the city linked to “five entities” involved in the construction.
“A tragedy of this magnitude demands a comprehensive and thorough investigation that includes both the construction site and the building which collapsed.
asserted
which → cave → site
That has already begun,” Mamdani said at a press conference Thursday.

it → determine → collapse
“I believe the collapse may have been preventable.”

Two children were among the dead, officials said Thursday, while terrifying photos showed a neighboring building with the wall sloughed off — and placid bedrooms and clothing-filled closets next door exposed to the chasm.

Work was eventually allowed to continue in May when safety structures were erected, according to DOB officials.

Work reportedly began in September 2025 with the demolition of a longstanding one-story storefront at 2625 Bedford Ave. to make way for what was initially going to be a 10-story building, and then a three-floor, 25,000-square-foot mixed-use building.

Mamdani, asked about the March DOB report that found cracks in the facade of the collapsed building, said he was “incredibly troubled.”
asserted
he → ask → building
“These are the examples of why we are conducting a full and thorough investigation, and why the investigation will not stop at the sites that we are here to speak about today, but will extend to any and all sites those who operated these sites are currently operating across our city,” he said.
asserted
he → conduct → city
There were “approximately 100 other sites across the city” associated with the “five main entities” involved in the construction, Mamdani said, though he did not elaborate on whether those were active construction jobs or standing buildings.
asserted
those → be → construction
“Our Department of Buildings is commencing sweeps of those sites today,” the mayor said.

DOB commissioner Ahmed Tigani said that while the report about the facade was issued the same month as the stop-work order, it was not the cause of the directive.
asserted
it → say → directive
“There were no violations or 311 complaints related to that in advance,” Tigani said, before Mamdani chimed in.

Mamdani → be → advance
Records show violations issued to 1321 Flatbush Ave. consisted largely of complaints about varmints, smoke detectors and peeling lead paint — but no structural issues were flagged until construction began next door.
The owner of the collapsed building, Olufemi Falade, was sentenced to a dozen days in jail in 2009 after 12 of his buildings racked up over 1,800 DOB violations over residents living in squalor.
asserted
12 → show → squalor
“This owner is perhaps one of the most egregious examples we’ve seen citywide of flouting the law and forcing his residents to live in horrible conditions,” Housing Preservation and Development officials said at the time, adding the city spent nearly $200,000 on emergency work to repair Falade’s buildings.
asserted
city → see → buildings
Some 80 violations at a single building — just down the road from the site of the collapse — were deemed “immediately hazardous” and cost the city about $17,000 to repair.
