In an Action News exclusive, surveillance video shows workers roaming around the site at 300 Hunting Park Avenue when the roof collapsed.
Reverend Carlos Diaz was in his church office at Faith Tabernacle Assembly across the street around 1:00 p.m. when he heard the noise.
"First of all, I thought, 'I hope no one was hurt,' main thing. I know there were a lot of crew people walking back and forth," Reverend Diaz said.
Four men crawled out of the rubble, including an 84-year-old construction worker - a man described as extremely fit who only suffered a few bumps and bruises.
Of the four who were hurt, two were taken to Albert Einstein Medical Center and the other two were taken to Temple University Hospital.
OSHA and L&I were on the scene investigating.

Action News has tried contacting Axis Construction, but we have yet to hear a response.
The city says the company hasn't had any problems at this site since it started construction in October.
