As a size reference, I believe the white item just above the bottom right (uncapped) super-column is a port-a-potty. So it's about 9 poop shacks in total area.

I'd like to think this unit of measurement is called a "pubit"

How tall is each mega column? I imagine at least 3 storeys high?

The architectural plans show these steel columns encased in concrete all the way up to the 58th floor.

I meant, how tall is each "section" of a mega column? CIBC Square has them in the height of 3 storeys for example.

 

[ChesterCopperpot]

I'd imagine they are just regular floor to floor heights.
CIBC Square is a steel structure - this is concrete - they will still have to be tied into the poured concrete floor structure.

edit: we'll see soon enough

Also from the planning docs...these are concrete encased so kinda hard to tell but looks like the steel could reach grade. (Does that count as "at grade"? ? )

And that confirms that bunk parking as well.

Is it just me, or is the rebar density of the floor really low?

Plus, I can't spot any conduits or post-tensioning cables, or anything else other than rebar!

You can see a few conduits on Benito's third last photo, still a really small amount though.

Here is a close up view of the base plates. The floor has double row of rebar and is almost 9" thick.

Rebar porn?

Deaf_Torontian - Oct 18
AdamS - Oct 29
Contra - Oct 31
Lyphe - Oct 32 (lol)
Koops65 - Nov 6

Thanks to everyone who has weighed in to date!

So many rebars... Why not make this column full metal instead of concrete? Is it cheaper that way?

Now I finally have some idea what everyone's been talking about when super columns have been mentioned
