Press conference
Commissioner Tigani and Deputy Mayor Bozorg hold news conference, confirm no movement and ongoing repairs.
Repairs begin, some evacuations lifted
Workers begin shoring damaged columns; residents allowed back into several of the evacuated buildings.
Stabilization assessment
Officials conduct floor-by-floor inspection up to the 37th floor; find no additional movement, giving contractors greenlight for emergency shoring.
Building Stabilized, No Movement Detected
DOB Commissioner Tigani announces no further movement after hours of monitoring, lifting some evacuation orders. Risk assessments continue floor-by-floor to determine repair viability.
Structural damage identified
Inspectors discover two buckled columns on the 21st and 22nd floors, with sagging between floors 21 and 26.
Collapse Zone Established
Officials establish a collapse zone, evacuate the building and nine surrounding structures, and close nearby streets as the building continues to shift.
DOB Inspection
Department of Buildings inspectors arrive and observe buckled structural columns, multiple cracks, and sagging floors on the 21st floor.
Evacuations ordered
Construction workers and occupants of seven adjacent buildings, including a school with ~400 children, are evacuated as a precaution. Nearby streets closed.
FDNY Receives Call
FDNY receives reports of a structural issue at the active construction site and dispatches units.
Buckled Columns Discovered, Evacuations Begin
At the former Pfizer HQ conversion site, construction workers spot buckling columns. The fire department is called, and nearby buildings—including a school, diplomatic offices, and hotels—are evacuated.
Emergency calls
NYC Fire Department receives reports of falling bricks at the 38-story tower at 235 East 42nd Street; firefighters and building inspectors dispatched.
Worker Alert
Construction workers at 235 East 42nd Street notice cracking sounds and structural beam buckling and alert the FDNY.
Steel Columns Buckle
Two steel columns buckle on the 21st floor of the former Pfizer building during conversion work, causing evacuations and a temporary halt to the project.
Structural Risk Assessment Underway
Mayor Mamdani labels the situation 'extremely serious.' Fire Chief Esposito warns of a possible localized collapse. DOB inspectors and firefighters survey multiple cracks and sagging floors.
A structural failure at the country’s largest office-to-residential conversion forces evacuations and spotlights the urgent need for real-time monitoring tech in adaptive reuse projects.
The structural scare at a former Pfizer headquarters undergoing luxury residential conversion exposes the risks in adaptive reuse projects and amplifies the need for IoT-based structural monitoring and digital twin technology in aging buildings.

The evacuation of nine buildings after structural failure at a Manhattan office-to-residential conversion underscores the critical role of real-time sensors, digital twins, and AI-driven risk assessment. Proptech solutions could have detected load anomalies earlier, and their absence will now spur regulatory and insurer demands for continuous structural health monitoring in adaptive reuse projects.
The buckling of steel columns at the former Pfizer HQ conversion into 1,600 apartments highlights the structural complexities that proptech solutions—from digital twins to real-time monitoring—are designed to mitigate. Experts say the incident doesn't undermine confidence in adaptive reuse but underscores the need for advanced engineering technology to ensure safety and efficiency.
