I was almost certain that there would be some mechanical above the office floors. Maybe the concrete core does not need to be raised further in order to handle equipment servicing for the elevators and maintainence...??
I thought this was the same tree. Yes, definitely been there since xmas. You can see if if you look closely at some of my earlier pics from a few months ago.
I don't want this to top out. I want a surprise notification that they are adding 20 floors or something totally crazy like that!
The tree gets flown up on the last piece of steel on a steel building, when the building has been completed without death or serious injury. Trees don't go up for the concrete top-out (unless someone somewhere is trying to start a new tradition, or appropriate an old one)
