I think it is indeed more likely that it hasn't changed and the blurb I read had incorrect information/typo. However, there is also some possibility at this point that the developer made a change impacting the unit count and simply forgot to have you directly informed at least as of yet......

The hole is filled with water - sometimes clay laden water - to help keep the sides from caving in before the sleeve is driven down.






Spinning off the soil.

What do they do with all that clay? Is it trucked off somewhere? Used for anything?
In the Quad Cities there's an artist who makes knick knacks out of Mississippi River clay (ibloom.com). I'm curious if good clay like that is going anywhere interesting. With all the Chicago construction, that is a lot of clay being mined.

We have a couple new beaches that need to be made to straighten out LSD, seems like a good place to start dumping excess earth.

I have it on good authority that Phase 1 will not have more than 800 units in it, so whatever source had it at 900 was incorrect. When I worked on it, the number was 792 so that is consistent with my last first hand information.

Seems there was quite a large pour here over the weekend. Image from http://www.sloopin.com

It's soil, so the excavation contractor will typically haul it away and sell it to some other project. Clay like this can be used to cap landfills or other environmental remediation, etc. I don't think it compacts very well, so you typically wouldn't use it to backfill around foundations or for roadway grading. But it probably could be used for lakefill projects, golf courses, or other terraforming.

I assume artist-grade clays are probably mined for that purpose and kept free of impurities, not dredged up as spoil from a construction site... although artists are certainly free to get their clay from the bottom of a caisson if they wish... :shrug:

It'd be interesting for an artist to pitch the idea of furnishing a new building with clay artwork crafted out of the clay recovered from that building's caissons.

That's a wrap on the caissons.

Were there air compressors on site to grind rock-socketed caissons? I dont recall seeing any in photos posted here.
Who's the general contractor? It will be great to see some vertical structure rising here soon!

Apparently you don't always need compressors.

McHugh is the GC.

They have permits for the first 12-levels and for the tower crane.

It's sheeting time...

Awesome. About a month till crane gets installed?

Don't put a timeline on it They'll drive sheeting around the perimeter and the core. Then they've got to excavate the core area, build up the mat..... Just enjoy the process.

An altogether silly thing to tell someone when in fact there very much is a - rather precise - timeline on it....

^^^ Yeah, but do project managers for private projects publish their schedules? And are those fixed in stone? The PM may have a date on his calendar for when the crane gets installed, but we don't have it.

Thanks for pointing out the obvious of what I was eluding to.
