RAW Video: What Caused the Philly Garage Collapse? CHOP Structural Failure

Raw footage from the scene of the 7-story CHOP parking garage collapse in Philadelphia. Jeff Ostroff looks at the structural failure that occurred during the construction of the Philly parking garage in Grays Ferry and the investigation into what went wrong.

The Incident: The collapse occurred on Wednesday, April 8, 2026, around 2:15 p.m. at the corner of 30th Street and Grays Ferry Avenue.
The Cause: A precast concrete roof segment failed during installation, triggering a "progressive collapse" through all seven levels of the stairwell tower.
The Victims: Tragically, three ironworkers from Local 401 lost their lives. Stepan Shevchuk was rescued initially but died at a hospital; the bodies of Matthew Kane and Mark Scott Jr. were recovered early Monday morning, April 13, following a painstaking deconstruction of the unstable structure.
Investigation: The city has launched an independent investigation, and OSHA is also conducting a federal probe that is expected to take up to six months.

We'll examine several potential root causes and study raw video to determine what caused the Philly Garage Collapse and the CHOP Structural Failure.
