Developer of sagging NYC skyscraper is accused of carrying out UNAUTHORIZED construction after beams collapsed and floors buckled, sparking fears of partial collapse onto Midtown Manhattan

The developer of a sagging Midtown Manhattan skyscraper has been accused of carrying out unauthorized construction after two beams buckled and several floors collapsed.

The owner of the the 37-story office building on East 42nd Street performed construction that went beyond previously approved plans, according to a complaint filed by the New York City Department of Buildings (DOB) on Tuesday.

Specifics of the complaint against the owner, listed as 235 Fee Owner LLC, are not yet publicly available but the DOB’s portal stated that ‘no support of excavation has been approved.’

Construction crews evacuated the skyscraper just after 8am Tuesday after they discovered that two support beams had begun to buckle.

The 21st to 26th floors of the building near Grand Central Terminal caved in under stress, officials say. Multiple cracks and sagging floors have been reported throughout the high-rise.

Footage filmed by workers showed the massive silver beams on the 21st and 22nd floors buckling and bending just moments before the floor started to crumble.

The building remains unstable, but experts insist that any collapse would be localized and that, due to its steel supports, the high-rise won’t come toppling down.

The skyscraper, which has been under renovation since 2024, was also issued seven violations from the Office of Administrative Trials and Hearings (OATH) last year, all related to construction safety.

The OATH violations resulted in over $32,000 in penalties and have since been resolved, public records showed.

One of the penalties was a $10,000 violation for failing to notify the DOB of a construction incident that resulted in injury.

The DOB also issued 22 violations at the address, dating back to 2022, according to the agency’s public portal. A majority of the violations stemmed from failing to file elevator inspection and testing reports.

Thirteen complaints remain active, with 235 Fee Owner LLC owing the city $39,000 in penalties.

The skyscraper, which once housed pharmaceutical giant Pfizer, was being converted into a 1,500-unit luxury apartment complex.

All workers have been accounted for as of 1pm, the FDNY said. 

A site worker has accused the construction project’s general contractor of irresponsibility following the emergency evacuation. 

‘The general contractor chose to go non‑union for this project. All we want is responsible construction in the City of New York,’ Cliff Johnson, of Steamfitters Local 638, told PIX 11.

‘They did not shore up the job correctly. The beams started crumbling, the floors started crumbling, and they might have to evacuate the other side.’ 

Johnson said the project was a ‘total renovation’ and that crews were gutting the entire building. 

Renovation plans included adding 11 extra floors to the high-rise, he added. 

The DOB does have an active permit for the ongoing construction work, officials said.

Metro Loft Management is understood to be overseeing the building renovations. 

In a statement to PIX, the company said: ‘First and foremost, we want to thank the FDNY, NYPD, and DOB for their quick response. The safety of everyone at and surrounding the building is our number one priority.

‘We’re thankful there were no injuries, and as the DOB clarified, no debris fell from the building. We want to confirm that the affected area is a small section of one of the two buildings on this site. As the FDNY spokesperson noted, the entire building itself is not at risk of collapse.’

Metro Loft has not responded to the Daily Mail’s request for comment. 

DOB inspectors responded to the under-construction building on Tuesday following the evacuations and are actively investigating the situation.

No injuries have been reported, but an evacuation was ordered as a precaution. Eight nearby buildings have also been evacuated as emergency crews attend the scene. 

‘It’s a very serious situation because the box beams, the steel beams, have started to bend and deflect from the weight,’ FDNY Chief of Department John Esposito said. 

‘We evacuated the building and started evacuations of surrounding buildings. The building has continued to move since we have been on the scene.’

Officials used ‘specialized tools’ to monitor the building’s movement in ‘centimeters or a fraction of an inch.’

Mayor Zohran Mamdani is on the scene, which he has called an ‘extremely serious situation.’

The mayor urged anyone in the area to follow the instructions of the first responders on site.

‘Now luckily there have been no injuries to report at this time, all workers are accounted for, the building has been evacuated, a number of tall buildings in the area are also being evacuated at this time, a school with about 400 children has also been evacuated,’ he said.

Approximately 150 firefighters and EMS members responded to the scene, as well as representatives from the DOB and NYC Emergency Management.
