Steel Columns Buckle at Manhattan Office-to-Apartment Project Site
Tap title to read story
New York: Two steel columns buckled this week inside the former Pfizer headquarters in midtown Manhattan, prompting evacuations and halting work on one of the nation's largest office-to-apartment conversions. Crews installed temporary supports on the 21st floor while officials paused construction and began an investigation to assess structural safety before any further work.
City and project officials said the plan calls for converting two buildings—one built in 1909 and another in the 1960s—into roughly 1,600 apartments by adding more than a dozen stories and redesigning the other structure. Engineers this week stressed the complexity of adaptive reuse; investigators are reviewing load-bearing capacity and will determine conditions for safely resuming construction.
