I used to walk byt this building all the time when I was working in the city. That was years ago. I had no idea Pfizer vacated the building and it was being converted.
Anyone, the video seems to show aluminum wall beams not support beams although something above the wall beams must have caved in a little for those wall beams to bend like that.
We don't often think about it but building a high rise building takes a lot of smart thinking or you will get collapsed. The stresses these building have to endure constantly is a lot more than what people think.
