What's going on here? There is nothing permanent about this.

What do you mean? They are building the climbing form assembly for the core. This is totally temporary and features reusable forms that open and close to allow workers inside to place the rebar before closing back up and being filled with concrete.

Thank you. I knew it was temporary I just didn't know its function. Now I do.

^Understandable. Looks permanent because the formwork is shiny and new. Typically, they're orange and rusty but the problem is that GCs don't have any old ones lying around in their equipment yards thanks to the most tremendous construction boom in Chicago history! They're all spoken for!

So much respect for these construction workers. Not only do they work in dangerous and precarious situations, now it's the weather. The guy above is doing something with that 2x4 while balancing on minimal foot support all while carrying a cumbersome tool belt and safety harness.

awesome pics. can't wait to watch these two massive elevator cores rise above LSD

Because of the three cranes working together do the two towers have to rise simultaneously level for level?

Since all 3 cranes are luffers, they have a lot of flexibility. I would expect that we will always see the taller one jump first and the medium one jump second. The towers should rise roughly floor for floor once the climbing cores are both built (barring unforeseen issues). The small crane is probably at it's ultimate height since it is only there for a short time to support the podium.

How cool would it be if both buildings shared the same slab for each floor. That would be so huge taking up the whole site and fun to watch.

Wow. Stellar shots, Harry. Gracias

More likely some squeezed between the forms - which would be joined right here.

Haha, my thoughts exactly. If feel like these two towers are basically part of Site I's construction in that sense.
