Does anyone know how many workers there are on that site on any given day? These videos I must assume are done after working hours because there is so little going on. It's incredible to watch how this building takes shape so quickly. When you think about every nut and bolt and weld that needs to take place it's impressive.
A big tell is how many cranes are in the air. I would imagine most of these videos are shot on the weekend, but I have witnessed a flyover around 12:15pm when we are on break.
