Philadelphia is inspecting hundreds of demolition sites in the wake of a building collapse that killed six people and injured at least 13.

The Department of Licenses and Inspections says it has 300 open demolition permits throughout the city. Inspectors have visited about 30 of these sites and plan to get to the rest by next week.

A demolition crew was tearing down a four-story building on busy Market Street when it collapsed Wednesday onto a Salvation Army thrift shop next door, trapping store employees and others.

The department says it has inspected all four construction and demolition sites connected to Griffin Campbell Construction, the demolition contractor involved in the collapse. The city found violations at two sites and ordered a halt to the work.
