NYC officials are investigating why part of a building undergoing demolition collapsed this morning causing scaffolding to fall onto an MTA bus, resulting in minor injuries to 18 people. Part of the structure, at 301 West 125th Street, is still standing although “a large amount of it did fall down,” says a Fire Department spokesperson. The incident is thought to have occurred just before 9:26 a.m. and was brought under control at about 3 p.m., the spokesperson says.

 The Dept. of Buildings received a complaint about the site on September 7, but its inspectors did not find any conditions that warranted a violation, a DOB spokesperson says. The agency says it issued a work permit to Queens-based DiSano Construction, the demolition contractor, in June.
Details on the exact work being done at the time of the collapse have not been disclosed. DiSano referred calls to Harco Construction, the general contractor, which says it cannot comment as the incident is under investigation.
In 2007, the building’s owner was registered with the Dept. of Finance as 301-303 West 125 LLC, which could not be reached for comment by press time.
