Sure, that has played a role, but at this point, it's a scapegoat.

Yes he did and we were all not happy about it...so that seems show that nothing "unplanned" for has occured yet.

Wow, that doesn't look real... it looks like it belongs in a video game or something!

Looks like someone uses a little High Dynamic Range in their photos. (HDR)

Looks good.

[WonderlandPark]

That IS a nice HDR image.

I had to look it up myself. If you blow the pic up I looks even more sureal.

Am I imagining things, or can you see the river reflected in the upper windows of 77 W Wacker?

No, you are correct. Think about it, it makes since because this picture was taken from so much higher than those windows with the river in them that it makes sense.

In terms of the progress, this is typical for a concrete building that has 3 levels of rakers (internal bracing). There is a very methodical process that must be followed when excavating/bracing in a situation that is similar to this. Once the bracing is complete, and the building has "bottomed out", then it will still be a slow process for the actual lower floors to be placed around the bracing. Please keep in mind that the reason the core was placed in the first reason was to "kick" the exterior sheeting to a location where the loads can be transfered across the job.

^ Thanks a lot CJ. Glad to see you here on the forum, and hope you come regularly.

Thanks for the explanation on the forum and welcome.

Are you a superintendent on a construction site?

Hope that you can offer more input and explanation.

Thanks Supt11CJ. Sound like you maybe the go to guy for technical questions that pop up from those of us who aren't experts in the construction trades. Welcome

Also I thank you.

We appreciate any true inside construction input.

We are hungry for the real working knowledge that you possess and are happy any time you can contribute.

Great first post.

....this has got to be one of the most complex foundations I've seen in any of these forums.......can anyone think of a building trickier than this one?

This photo needs to be on the last page.

I have a couple questions re the bracing:

Is the bracing there to prevent potential foundation problems for the adjacent LaSalle Wacker building?

And is bracing to this degree very common?

Yes, its to keep the adjoining foundations for collapsing, but its also just to keep the walls of the hole in general from falling in.

Not quite to this degree its not, but you do often see bracers like this being used to keep the sides up. They actually are using them at the Elysian right now, and probably will have to use them at 300 n lasalle... You'd have to ask Otis to be sure about 300 lasalle though...
