Firefighters notice significant damage to World Trade Center Building 7 at some point after the Twin Towers collapsed. Butch Brandies tells other firefighters that nobody is to go into WTC 7 because of creaking and noises coming out of there. [Firehouse Magazine, 9/9/2002] According to Deputy Chief Peter Hayden, there is a bulge in the southwest corner of the building between floors 10 and 13. [Firehouse Magazine, 9/2/2002] Battalion Chief John Norman will later recall, “At the edge of the south face you could see that it was very heavily damaged.” [Firehouse Magazine, 9/2/2002] Deputy Chief Nick Visconti will recall, “A big chunk of the lower floors had been taken out on the Vesey Street side.” [Firehouse Magazine, 9/9/2002] Captain Chris Boyle will say, “On the south side of [WTC] 7 there had to be a hole 20 stories tall in the building, with fire on several floors.” [Firehouse Magazine, 9/9/2002] One witness will describe looking at the south face of the building and seeing “broken windows, damage to the building, I-beams sticking out.” Another witness will describe seeing 10 to 15 floors where “the corner I-beam was missing,” and add that “there were more floors that had damage throughout the front facade of the building and several floors were completely exposed.” [Aegis Insurance Services, Inc. v. 7 World Trade Center Company, LP, 12/4/2013 
] Richard Rotanz, the deputy director of New York’s Office of Emergency Management, assesses the condition of WTC 7 at around 12:30 p.m. “We’re looking at the upper floors of Tower 7,” he will recall. “The skin of the building or the outside skirt of the building was taken out,” he will say. “You could see columns gone, floors collapsed, heavy smoke coming out, and fire.” [BBC, 7/6/2008; BBC, 10/17/2008] WTC 7 will collapse at around 5:20 p.m. (see (5:20 p.m.) September 11, 2001).

12:00 p.m. September 11, 2001: Engineer at WTC Site Predicts the Collapse of Building 7
An engineer at the World Trade Center site correctly predicts that WTC Building 7 is going to collapse. Deputy Chief Peter Hayden of the New York Fire Department will later recall: “We had our special operations people set up surveying instruments to monitor and see if there was any movement of [WTC 7]. We were concerned of the possibility of collapse of the building. And we had a discussion with one particular engineer there, and we asked him, if we allowed it to burn could we anticipate a collapse, and if so, how soon?” The engineer apparently predicts correctly that WTC 7 will collapse and also the time it will take before it comes down. Hayden will recall, “He said yes and he gave an approximate time of five to six hours, which was pretty much right on the money because the building collapsed about 5 o’clock that afternoon.” Hayden will not reveal the name of this engineer. [BBC, 7/6/2008; Aegis Insurance Services, Inc. v. 7 World Trade Center Company, LP, 12/4/2013 ] WTC 7 will collapse at about 5:20 p.m. (see (5:20 p.m.) September 11, 2001), indicating that the engineer makes his prediction around midday or shortly after.
