Definitely didn’t have ANY of its fire safety construction completed. What most people don’t realize in a wood-frame building is that the gypsum board on the walls is the main thing preventing a localized fire from becoming a full-on conflagration. The construction was still in its relatively early stages - no gyp board on the interiors, no fire-sprinklers installed yet - and so was pretty much a lost cause.
For the record, I work near the building (I could see the smoke from my office), and like an earlier commenter said, there were VERY FEW people in the building, that day working, fortunately. It wasn’t completely abandoned, but a friend who worked in the building from which the video was shot said that it was fairly empty of people when the fire started.
@awjt He was on the fifth floor (four stories of wood-frame construction atop a concrete ground floor). That’s about 48’ off the ground at a minimum (possibly as high as 60’, depending on the height of the concrete plinth).
