AGREED!
I had to look twice it look so real!

This project has to be one of the more Architecturally sophisticated projects I’ve seen here in Atlanta since Lilli.
1105 was a possible contender for innovative design until they eliminated the diagonal bracing on the northern side of the building – then the design feature on the Southern side just felt gimmicky. Yes, I know it was never structurally necessary, but hey, lets have a little follow-through with the design theme.

I wonder if it will have that smokey colored glass. It would be a nice change of pace from all of the blue glass.

This site looks massive and they are now just halfway through the site prep.

I hear some large crane will be setup on this site today. I doubt it is a tower crane, but who knows.

Those windows look like a window washers nightmare.

Since when do we care about window washers on here...?

I'm surprised the drone/AI industry hasnt taken over this market yet.

Crane is up and they’re starting on the stairs:

It looks like crane #2 is coming soon.

WOW, I had no idea it was that deep.......

I don't understand how they can retain that much soil by just stacking more timbers behind taller steel posts. It would seem that the steel posts would have to be thicker and further in the ground the higher you ascend. I can't imagine the added soil weight after a few days of steady rain.

If I was a contractor, I would be biting my nails until I could get some concrete walls poured.

Structural Composite Lumber (SCL) has amazing properties compared to natural wood timber, if that's in fact what they're using.

What you can't see is that those steel piles (solider piles) extend easily 2-3 times deeper below the surface than they extend above the finished excavation level. Of course water is always a concern but these walls are very temporary until the concrete foundation wall can be poured.

Another detail not mentioned in the video - deep excavation pile & lagging walls typically have tie-backs (as these walls clearly have too). These tie-backs further anchor the wall into the ground or solid rock and fight the natural tendency for the wall to want to overturn.

Fascinating stuff - you want to be even more awed? Look up the pile. lagging, and slurry walls it took to make the water-logged (original) World Trade Center Site suitable for high-rise construction.

Nice explanation.

The "Tie-Backs" must be the circular formations between the piles.

Not sure how you get piles that long unless there are multiple pile sections fastened together in some way and driven into the ground.

Interesting though.

A little hard to tell exactly what we're looking at but I think you're right - those are the tie-backs.

And yes you're right - piles have to be combined in-situ (mechanically or more likely by welding) since you're restricted in length by what can fit on a truck.

CODA was another recent project that went pretty deep to conceal parking (https://atlanta.curbed.com/2017/8/17...gia-tech-tower). Much like this project, it's pretty easy to see why underground parking is 5-10x more expensive than the sad above-ground parking podium that litters Midtown.

Second crane is up.
