good question, i was wondering the same.

this is the most thoroughly i've ever followed a supertall construction, and learning about all the details is fascinating.

Will there be 3 cores? Does anyone have any decent floor plans?

These are super-old, but I imagine that at least the number of cores hasn't changed:

Stopped by the site for a quick update today. It's mind-boggling how much is going on at this site. The organized chaos is so impressive.

West Core:

East Core:

Here's a side-by-side comparison between the mat pour on 2/4 and the site today.

Cool comparison Nick. Its insane how fast thier moving. Can we get that split shot at the end of every month if your in the area?

I can try. I think at a certain point the project will progress too high, and I'm not sure this particular angle will be as dramatic. If I can retrace my steps form the mat pour shoot, and get the alignment right, I'll do a similar treatment with some wider, more distant angles.

This is how I feel when I look down at the site - except I'm not exactly sure how it all works, ha.

Trusses are for large cantilevers like 150 or to bridge large column free clear spans like at Block 37. My guess is that this is supported right on the columns you see in the photos. If you look at the drawing in the top of the thread, the columns go right through upper Wacker and support the middle section above. I don't think we will see anything unusual for this.

Correct. I had originally hoped the middle tower would be suspended by some elaborate poured-in-place concrete truss system that we'd be eye-level with from the elevated traces South of the site, but that's not the case

In this screengrab from one of my photos, you can see quite a few columns already in-place (particularly the one smak in the middle of the frame), and other caisson top awaiting the columns to grow from them.

Then there's this rendering that further puts those hopes to rest. But if you look close, it does appear there may be some fun concrete or steel acrobatics happening within the interior support structure of the glass cube-like structure. Time will tell...

How many square feet is this building going to be in total? It's massive.

Wikipedia says 1,414,378 sq ft

https://en.wikipedia.org/wiki/Wanda_Vista

Which is SIGNIFICANTLY less than the Sears Tower at 4,477,800 sq ft.

That's mind boggling at first, but then I thought about it. Vista is about 31% the size of Sears Tower by square footage. If you look at the building's repsecitve massing, Vista (3 towers of differing heights) almost resembles 1/3 of Sears' bundled tube structure (9 towers of differing heights)

LouisVanDerWright · #13 Posted **Mar 14, 2017, 5:46 PM**

The Sears Tower is big compared to just about any building. Believe it or not, but the Sears Tower is still the largest stand alone tower in the world by floor area. If you read the wikipedia list Sears is still 37th overall among all buildings and ranked amongst giant factories, airports, and convention centers. The only other skyscrapers that exceed it's total area are multi-tower complexes like Ren Center.

Despite all the latest and greatest super and mega tall buildings, Sears is still the beefiest tower on the block by a longshot. The amount of space in that building is mind boggling given it's height.

Representing the city of big shoulders very well, even if its "tallest building in the world" glory days are behind it.

Cool floorplan comparison between the Seats and Burj Dubai. Maybe someone could scale in the Vista plans that were just posted for comparison? Sears is definitely the leader in usable SF, that's for sure.

Yeah, going off the topped out height can be tricky at first but your logic seems sound.

^^ Wow, looks like we are about to see a large unified floor plate across the entire tower footprint, spanning the lower level road.
Where is the parking here? I expected to see some slightly angled slabs here where cars will be parked on, but yet to see evidence of it.

Zerton · #19 Posted **Mar 14, 2017, 9:56 PM**

Thanks for the plans, James_Mac.

I didn't realize from the renderings that the 3 "tubes" are actually slightly staggered in plan.

They might as well be building this IN China as fast as it's going. Not much snow gathered on it for sure. From today
