Great update! Progress seems to really be moving along. I was hoping Waterview would at least be above street level like 300 N Lasalle.

It does not appear that the area around the core is being excavated anywhere near the depth of WT. Does anyone know if this a function of the height of the building, the proximity of the water table or simply a function of the developer's intended use of the space?

BTW, thanks again for the great pics!

I think the reason being that there will be a terraced, river-walk area pretty close to the river, which will be paved-over; that is why the building footprint is set back from the river's edge and why they are not drilling down as deeply as compared to Waterview Tower.

Maybe someone can clarify.. What is the purpose of those dozens and dozens of metal pipes going into the core? Same thing with the Waterview. Hard to imagine that they all are sewer lines etc. Do they keep the walls up or something?

Those are called "rakers." They serve to support the outside walls of the excavated site and are only temporary.

Has anyone spoken to the construction crew on this site? I'm interested to know whether they had the same foundational problems that Trump's crew had to overcome.

Question for the architects and engineers here: Is it normal to be erecting the tower crane at this point in the construction of a building?

^ the boom is now attached to the tower crane, but it's kind of hard to see

Why do they build so many floors of the core before they pour the usable space of the floor, whatever you call that.

The core needs to have a head start on the rest of the floorplate for a couple of different reasons: a) there needs to be room for the hydraulic formwork system to work its magic - not to mention there just needs to be room for the formwork in general (usually requires 2 to 3 stories), b) since the core typically provides most of the building's lateral stability, the core must sufficiently cure before it can be expected to provide any usable strength.

Second crane going up today on the river side. Not sure I've ever seen this many cranes up at the same time. I thought we'd have run out by now.
