City officials ordered a partial construction shutdown at 750 Third Avenue after inspectors discovered unapproved modifications to several steel columns. This follows a troubling incident on July 7, when structural columns buckled and floors sagged at a nearby project, prompting evacuations and rerouting of bus lines due to fears of a potential collapse.2
In addition to the issues at 750 Third Avenue, inspections revealed that another office conversion project in the Financial District had cracked concrete beams that were repaired without proper notification to the city. This has raised alarms about the safety and oversight of ongoing construction projects in the city.

As investigations continue, the city is taking a cautious approach to ensure the safety of future conversions, with several projects ordered to pause or halt construction due to various issues, including missing paperwork and structural concerns.6
