Crews worked over the weekend to demolish the Children’s Hospital of Philadelphia parking garage that collapsed while under construction Wednesday in Grays Ferry.
A construction worker pulled from the rubble moments after the catastrophe died, and two others who were missing were “presumed deceased” Thursday after rescue dogs detected no signs of life, Mayor Cherelle Parker’s administration said. All three were members of Ironworkers Local 401.
Once the structure is knocked down, authorities intend to remove and search through the debris in an attempt to recover remains. Robots, drones, cadaver canines, a large crane and other equipment have been deployed to the area, city officials said.
Inspectors have been monitoring air quality during the demolition, and there have been no reports of elevated pollution, according to the Parker administration.
A corner stairwell being built for the seven-story garage came crashing down at around 2:15 p.m. April 8 at the 30th Street and Grays Ferry Avenue construction site, authorities have said.
Parker said Precast Services Inc., a subcontractor with an office in Berks County, was installing concrete floor decking and roof segments that had been manufactured off-site at the time.
“After placement, a precast roof segment failed and fell to the level below, literally triggering a progressive collapse of connected sections across all seven levels,” the mayor said during an initial briefing Wednesday.
She explained that the general contractor, Exton-based HSC Builders & Construction Manager, had acquired all eight required permits and had completed the proper inspections.
Parker has repeatedly promised a thorough and transparent investigation. The Occupational Safety and Health Administration, known as OSHA, is leading the probe. A spokesperson for Precast Services said the firm is working closely with those searching for answers.
"We are deeply heartbroken by the tragic loss of our three team members," the company spokesperson added. "We are offering our continued support to the families, as well as our entire team as we all grapple with this tragedy."
Grays Ferry Avenue remained closed Sunday between 34th and 28th streets, with cross traffic only permitted at those aforementioned roads. The Grays Ferry Shopping Center, a strip mall across the street, was also still shuttered.
Property records show that CHOP purchased the land two years ago for $24.75 million and planned to construct an employee-only garage with more than 1,000 spaces.
A community coalition has opposed the project, over concerns about air pollution, traffic and other issues.
