The wall of the vacant five-story mixed residential and commercial building at 211 East 34th Street partially collapsed around 11:30 a.m. on Thursday. A secondary collapse happened hours later.
Video from NewsCopter 7 and from an Eyewitness News camera on the ground showed a large portion of the side of the building had fallen. Debris was seen strewn outside the area which collapsed.
Hours later, officials said a second wall collapsed at the site. There were no injuries in that incident.
There was an ongoing excavation operation at the adjacent property, 209 3rd Avenue, in preparation for a new 35 story building.
The neighboring building, 213 E. 34th St, is being temporarily evacuated as a safety precaution.
