Workers installed emergency structural supports Wednesday at a midtown Manhattan high-rise after two mangled support beams and sagging floors forced mass evacuations, raising fresh questions about the city's ambitious push to convert aging office towers into residential housing. The incident at Pfizer's former headquarters near Grand Central Terminal exposed what Mayor Zohran Mamdani called "clearly a breakdown" in the conversion process.
Authorities discovered the structural damage on the 21st floor early Tuesday, triggering evacuations of nearby buildings and street closures in an area close to the Grand Central transit hub and the Chrysler Building. Fire Chief John Esposito said officials initially worried about "more of a localized collapse" rather than total building failure. The steel-framed building was empty except for workers when the damage was found.
Emergency Repairs and Regulatory Response
On-site contractors reentered the building late Tuesday after city officials completed a floor-by-floor inspection. They installed temporary shoring and beams throughout the 37-story structure. Photos from the city's Department of Buildings showed multiple steel rods inserted side-by-side next to one badly bent column. The emergency work is being supervised by the owner's engineer and an independent, third-party engineering firm hired by the owner.
Mamdani said no more movement had been detected in the building by Wednesday. He announced a "rigorous assessment" to ensure the plans and site fully comply with all codes before any non-emergency work proceeds. "As soon as we answer the emergency questions around safety in this moment, we are going to be conducting a full investigation as to how we got to this point," he said. "This is not a necessary consequence of an office to residential conversion. This, however, is clearly a breakdown in that process."
Project Scope and Developer Explanation
The renovation is billed as the largest office-to-residential conversion in the city's history, creating some 1,600 units of housing. The plans call for transforming a pair of office buildings by adding more than a dozen stories atop one tower and redesigning the other. Nathan Berman, founder of MetroLoft, the project developer, told The Wall Street Journal that the added weight from widening the top 15 or so floors of the building likely caused the damage. MetroLoft spokespersons didn't respond to requests for comment Wednesday, though the company has stressed the building isn't at risk of collapse.
Unionized construction workers protested near the site Wednesday, using a large inflatable rat, to slam the developers for using non-union workers. The future of the project remains uncertain while the cause of the structural issues is under investigation.
Disruption for Residents and Visitors
Residents and hotel guests were allowed back Wednesday into nearby buildings, though four other area buildings remained off limits. Sally Grant and Margaret Clark, who traveled from Scotland to see Bon Jovi perform at Madison Square Garden on Tuesday, were evacuated and told to leave their belongings, including credit cards, passports and medication. "They could have given us five minutes to grab our belongings, you know, instead of just saying everybody out, everybody out," Clark said. "We've been left with nothing. We slept in the streets last night. The police wouldn't help us. It's been awful. Absolutely it's ruined our holiday."
The streets around the site gradually returned to life Wednesday, with people walking dogs, pushing strollers and riding bikes. Some major streets remained closed, frustrating pedestrians and drivers. Elinor Ruskin, 94, was among those redirected by police after trying to get through a closed block. "These things happen," she said. "I don't know if they will catch the mistake or what they will do. Anyway, you know, this is New York City."
Antoine Mouthon, who works nearby at the United Nations, said he'd been skittish around the construction site after seeing the aftermath of a large sheet of metal falling from the building last August. "A whole year after I avoided that street," he said. "I thought they cleaned up their act."
Questions About Conversion Strategy
Sabrina DeRizzio, who lives in one of the converted office towers, questioned why developers keep trying to turn outdated office towers into modern housing. "It's not the best," she said, adding that it's impossible to hang anything on the concrete walls and the unit never feels properly insulated. "The infrastructure is just not the same," she said.
Mamdani, a Democrat, told reporters Wednesday that he considers the conversions "part of our answer to the housing crisis," but added that the projects must be done "safely and in a way that is fully accountable." New York, along with other major cities, has for years been pursuing ambitious overhauls to transform underused office space into residential buildings, in part to help struggling business districts and take strain off tight housing markets in need of more apartments.
Why This Matters:
The structural failure at what's supposed to be New York's largest office-to-residential conversion exposes the risks of rushing ambitious development projects without adequate oversight. While converting underused office space into housing sounds like an efficient market solution to the city's housing shortage, this incident demonstrates that regulatory compliance and construction quality can't be sacrificed for speed or scale. The project's use of non-union workers and the developer's apparent miscalculation about weight loads raise questions about cost-cutting measures that may compromise safety. With four buildings still evacuated and a full investigation pending, taxpayers and residents are bearing the costs of what the mayor himself called a "breakdown" in the process. The outcome will likely shape how cities balance their housing needs against the practical and safety challenges of repurposing aging commercial infrastructure.
