NYC 1,600-Unit Conversion Evacuates After Column Failure as Expert Warns More Reuse Risks

Summary
No injuries were reported after failing columns and sagging floors forced evacuation of the former Pfizer headquarters conversion at 235 East 42nd Street, a 1,600-apartment project now under investigation.
Older high-rises face added risk when converted for new uses because hidden structural aging, corrosion, or dormant design and construction flaws can surface once framing is altered, engineer Norma Jean Mattei said.
Mattei said the New York failure appears localized rather than a cascading collapse like New Orleans' 2019 Hard Rock disaster, suggesting the project could continue if investigators find a repairable, non-systemic cause.
New York may need tighter oversight if office-to-housing conversions accelerate, she said, pointing to Miami-Dade's 40-year structural assessment rule for older condominiums after Surfside.
