Two workers had to be rescued after a wall of a building collapsed onto an excavation site in North Philadelphia Friday.
The collapse took place along Ridge Avenue near Vineyard Street around 11:30 a.m., the Philadelphia Fire Department said.
The workers were pulled out just before noon and were being evaluated by medical staff, firefighters said.
"We were able to free and extricate two people who had been trapped by the collapse," Fire Commissioner Adam Thiel said.
Thiel was "optimistic" that the workers will recover as both were conscious when they were taken away in ambulances.
Workers said that a wall from a next door property, which has a sign on it that it is set for demolition, collapsed onto the site, pinning the two workers.
Licenses and Inspections issued demolition permits for both the property that collapsed and the excavation site. New construction is planned for both sites, L&I said.
L&I and the fire marshal investigated the incident.
