I didn't realize the frustrums were modulating East-West. I thought the action was all North-South.
But now that I look closer to a rendering, the waists do look narrower E-W than the bulges, don't they?

A frustum is not a triangle, it is a pyramid with the top cut off. This is the whole idea of the design, interlocking columns of pyramids with their heads cut off stacked next to each other. Sort of a Sears Tower of Infinity Columns:

See my original guess at it:

Now it will really start to grow especially if they can concoct and construct another tower crane to the east and just wait for the the warmth of spring to take hold.

The pouring cycle will certainly be faster in the 1st, 2nd and 3rd quarter of this year.


The foundation and the hardest parts are already done. I cannot wait for my yearly architectural river cruse once or twice a year in the early June summer and early Fall.


This one is going to be a fun one to watch, for sure.

Lots of the equipment on the gems site has been hauled away. Is this a bad sign for a construction start?

From the rendering it looks like the first inflection point is 12 floors above that big balcony on the middle tower. So the slope will change now.

Floor plate of 23 is a narrow point on the high-rise. Walls from 23 to 24 are sloping outward now.

Looks like the corner columns are shifting along with the floor-plates. Best I can tell, they don't look angled either.

I had just been assuming the columns would stay fixed and the plates would just cantilever out for the larger floors.

Anyone aware of what the tolerance for offset columns can be? Even if it isn't for angles like it is here, is there a rule of thumb? I always pegged tolerances as needed to be fractions of an inch, and small ones a that.

I wanted to go make some cool snow/winter photos this AM, but didn't have much luck. On my trek, I stopped by the Columbus bridge for a few shots of Vista though. This was the first time I noticed the offset columns, too. I originally assumed the same about the plates cantilevering further in/out. At first I thought (hoped for some odd reason) they were angled, but upon close inspection, they are more simply offset.

Full-height:

I'm sure you could ask the structural engineer (magnusson klemencic) via twitter about the columns, as they have answered past questions about the structure for this one.

Yeah. I've gone back and forth with them a couple times. They're super engaging on Twitter. Last time, we discussed the reasoning behind using concrete for the big angled columns in the lower/middle section vs. steel.

Good question, ha. I went back and looked at the frames I took before and after. Looks like he was climbing up. For what it's worth the photo was taken at 7:47am
