The fire chief said there appeared to be no support holding up dirt walls of more than 10 feet deep.
"They were digging the ditch, and they didn’t have the proper shoring is what it appears to be," said Chief Chas McGarvey of Lower Merion Township. "We’ve contacted the proper authorities to come and look at that."
Federal workplace authorities will investigate.
