So I wonder what the purpose of the half elevator door is for on floor 10. Can anyone shed some light on it?
My guess, is that the extra concrete in that location was needed for reinforcement for the crane supports. Think about the way forces move, if the crane is performing a pick and the weight is acting to pull the crane in towards the building, those supports are going to be pushing outwards. If the extra concrete isn't there, then there probably isn't enough reinforcing to prevent the supports from breaking out.
They'll probably cut the opening to full size once the crane is dismantled.
That is discussed earlier in this thread, posts 109 - 115.
It's topped off.

In that story: "Preparatory work is also being done on a hotel that will be built on the plot of land immediately to the west of 100 Northern Ave."
Did not realize it's going to be a hotel. I thought it was supposed to be a residential building.
I believe it's this.
Does anybody know just how much of the foundation work for 1 Harbor Shore Drive was included in the preparation for 100 Northern Avenue? There's been plenty of conversation that clearly the underground garage for 100 Northern extends outside of that building's footprint, but it isn't clear to me if it extends all the way under 1 Harbor Shore or just under the future street that will run up the western side of 100 Northern.
If the foundation for 1 Harbor Shore was built out entirely in the 100 Northern Ave preparation, I'd imagine that 1 Harbor Shore could rise pretty quickly.
