I don't know, i would MUCH rather have my terrace looking over grant park than looking at Mccormick and Comiskey park. But i guess having it flat there gives more units a somewhat better view of the park instead of a terrace beneath.

^ yeah, but putting the setbacks on the north side would preserve more sunlight to the park and reduce the harmful effect of shadows, at no penalty to the height or density of the building.

Clearly this building should actually overhang the park preventing any light or air whatsoever from entering. If we build it right, anyone entering Grant Park will immediately be smothered by the total lack of oxygen created by such a design.

Was driving in on the Stevenson today trying to picture this. It is going to look like the 2nd tallest in Chicago from that vantage point!

If Jahns will be the tallest of the South Loop highrises it seems OGP may have shrunk from previous reports.

Is OGP 829 or 892? Im seeing 829 in all stories on it now which would leave OBP as the tallest all residential at 843 correct?

829 was the original reported height, but I believe it's been reported on here as actually 892.

I'm wondering if a few of the caissons are setting atop the rock instead of drilling into it? I see there are no compressors or other rock caisson equipment on site, but that long liner does have teeth.

I still haven't seen that verified anywhere but here.
The official releases from the developer peg OGP at 829.

BVictor1 reported the 893' figure via an inside source. fingers X.

LouisVanDerWright Jan 24, 2017 7:32 PM

They usually don't roll out the compressors right away when they are doing rock cassions. Even at Vista the compressors didn't show up until towards the end of the drilling.

The compressors for Vista were there by early October and they try to get that stuff in early because rock caissons are more time consuming and tedious to drill.

Bvic's inside sources have historically been VERY reliable.

Bvic often knows more about the nitty-gritty detail specifics of some of these projects than the developers themselves know ;)

So I asked a few questions and here's what I got...


On height:

The precise height of the building is not yet determined but it will be somewhere in the range of what I've said before. They are still working through the amount of height needed to accommodate mechanicals and some other systems.

The facade:

The exposed exterior concrete will receive a field applied architectural coating, however this system has not yet been selected.

Regarding the foundation:

The building foundation system will be a combination of rock socketed and top of rock caissons.

The Dampener:

Currently that information isn't available.


I'm sure there are folks from McHugh and CH who peruse this forum and I just want to say thanks for what you do.

Keep Building Up!

Notyrview Feb 3, 2017 8:39 PM

Yes thank you to those folks and please err on the side of taller 🙏🏽

SamInTheLoop Feb 3, 2017 11:03 PM

^^ Nice intel. I'd been curious about the type of caissons this one would need, and had assumed it would have to include some socketed ones.

Field-applied architectural coating on concrete? Guesses as to what exactly we may be talking about here?

I think that's a fancy word for paint.

Ha - that's what's I was afraid of.....I like to see "cladding" - not "coating"........disappointingif they're really just painting the non-glazed surface of facade.......also, if this is the case, another window wall tower....which would be very cheap for a Grant Park facing tower.....
