Manhattan high-rise stable after emergency works on buckled columns

New York City authorities have stabilised a 37-storey tower in Midtown Manhattan after two columns buckled on the 21st floor. The building at 235 East 42nd Street, undergoing conversion from offices to apartments, prompted evacuations when the damage was discovered earlier this week.

MetroLoft, the developer, stated the structure is now stable. The company worked with the Department of Buildings to address the localised issue affecting a small section of the northwest corner. No portion of the building was ever at risk of collapse, according to the developer.

Founder Nathan Berman described the incident as a freak accident linked to added weight from the conversion work. He said the problem was confined to a roughly 20-by-20-foot area and involved supports that may not have been reinforced sufficiently or contained an undetected defect. Repairs will replace the damaged columns and raise sagging floors.

The project, converting the former Pfizer headquarters into around 1,600 apartments, remains on track for 2027 completion. It represents one of the largest office-to-residential conversions in the city. Berman rejected suggestions of broader structural shortcomings and noted the work followed approved engineering designs.

Emergency responders initially flagged an extremely dangerous situation, though concerns centred on potential localised collapse rather than total failure. Mayor Zohran Mamdani reported no further movement after stabilisation efforts and said a full investigation is underway.

Images shared by the Department of Buildings show the emergency support measures put in place. Construction professionals have followed the updates closely, with some discussing possible long-term repair approaches for similar cases involving load changes on existing frames.

The incident highlights challenges in adaptive reuse projects where original designs face new demands. In contexts like Kenya’s growing urban high-rise sector, such events draw attention to the value of detailed structural assessments before major modifications.

The tower near Grand Central Terminal now stands secure. Developer statements emphasise that the issue never threatened the overall integrity of the massive base. Work to restore affected areas continues while the broader conversion advances.
