Such a much needed gap filler from that last view. I just hope site I doesnt get a height chop.

Honest question -- why is it these towers seem to be rising so much faster than One Chicago, which started earlier?

maru2501 · #**230** Posted **Dec 24, 2019, 4:10 AM**

they are smaller

Thats going to be such a massive mat pour when the two are connected.

At one Chicago, the contractor installed a secant wall around the entire city block and excavated the entire site 15'-20' below grade. They also dug cores down 50' below grade with complex cofferdams before starting to come up. The underground construction of One Chicago is orders of magnitude more complex.

exciting to see it already rising

One Chicago needs to go down before it goes up, this one starts at grade.

the floor plates are already being done in sections. The mat pours were done a month or so ago.

Thanks! Exciting the buildings have different timelines--we'll get to see some cool construction for quite a while.

These look to be 2 very standard residential towers - with a shared large podium. This will be a great contrast to One Chicago which has secant walls, top down construction, and many levels of underground parking - next to an active subway station.

My bad Harry. I meant the floor plates stretching across the whole site for the big ass podium. Am I right in thinking the floor plates are going to be even for majority of both buildings throughout the podium? Possibly the towers as well?

Ah, yeah you are right but they stagger the work they wouldn't pour an entire floor at once
