The boom of a tower crane, with its engine on fire, collapsed July 26 at a high-rise construction site in Manhattan—hitting the face of the building across the street as it dropped its 16-ton load. City officials said they would investigate the mishap, which caused minor injuries to two firefighters and four others.

At a press conference, Jimmy Oddo, commissioner of the New York City Dept. of Buildings, said the 47-story residential project was fully permitted.

DOB also is checking the structural integrity of the damaged building and others in the area.
