The ambitious office-to-residential conversion added new construction to an existing building, causing supporting columns to buckle and steel beams to bend.
New York City has bet heavily on converting aging office buildings into apartments to help ease a housing shortage. But the threat of a partial collapse Tuesday by one such conversion in progress highlighted the significant challenges of those construction projects.
Fire officials said two columns had buckled on the 21st and 22nd floors, while floors were sagging between the 21st and 26th floors.
The conversion of an office building on East 42nd Street would be the largest project of its kind in New York City’s history, according to the architectural firm behind the plan.
