Those are hella thick rebar

Probably some sort of waterproofing. First a drainage layer to let the water flow to the bottom, than a barrier layer to protect the concrete that will eventually be poured between a form and the wood.
If the black layer is what I’ve seen elsewhere, it’s a fairly thick and stiff plastic layer formed into a grid of bumps. The result is a mostly-empty space between the blank and white layers down which a certain amount of water can flow, probably to be collected and pumped away by a dewatering system. I was able to observe this being constructed when the QNC building was built at UW.

They're building a hella tall tower.
Saw an extension crane in place today (parked along the YWCA wall). Couldn't see what it was moving, though.
Turns out it was moving the 'hella thick' rebar!
Here it is in action yesterday (from the Market Square garage):

More rebar was delivered today. This week they extended the area covered by cement. It looks like that will support rebar as well.

The rebar looks like it is at least six feet tall since it dwarfs the two guys who are working on it this morning.

This is a super interesting to watch. We're really getting to experience in this region for the first time a massive structure being built, and all that goes into it, in particular, the foundation. You'd never realize just how this it is, but obviously it's needed to support the weight.

Especially when building on sand! Building on the bedrock like they do in NYC is pretty neat too.
The mystery of the depression (bottom of pic) continues. It looks like workers are putting some rebar on its sides and bottom. Does anyone know what they are doing?

My guess is elevator shaft.

I am still going with sump pump pit...
Could be base for some sort of elevator shaft, I second the above.
That's my guess too. It's BIG!

I don't think it will be for a sump pump. This week more rebar was placed into the depression so my guess is it will be filled with cement. So it might be for an elevator shaft or something totally different. Obviously, construction is not my forte.

Seems like an odd location for the elevators though.

Not odd if you want to have a view to the outside from the elevators (our office building has that as well). And it might be quite a nice ride given the planned height of the building!
