7/22/2018 Update:

Excavation for the skyscraper seems to have bottomed out with the appearance of a crane base(?) at 5th Ave & Union St and the beginnings of the skyscraper core. Hotel tower @ level -3, approximately.

This is about to get really interesting. I am looking forward to this new core construction technique they are going to use.

Northeast corner they're laying down forms for the third crane base

A lot of form work going on for the floor / core even as the excavation continues...

You can see the crane base is now installed (just waiting for the concrete) and the forms for the "core" on the construction cam.

if yo look at the webcam you can see the three outlines for the core steel plate system

I am guessing but it sure looks like they only have a couple of days of dirt removal left and that conveyor system will be gone sometime next week. I guess I need to scroll back but how much time were they predicting this will shave off the core construction......1/3?

A discussion of that is on this page.

I keep wondering if all the tower developer/construction world is watching this new core construction technique closely to see how it turns out. If it really does shave $millions and gets tenants paying rent 7 months earlier than current construction times, I can see several future projects that are on the fence all of a sudden be a go with these new and improved economics.

How nice would it be if this project is what gets 4/C back on the table?

Or maybe some other mystery developer will buy up an unlimited height parcel and propose something incredible. Only time will tell I guess!

Will the old pedestrian concourse (tunnel) from Union Square connect to this or is that gone forever?

 

[testdrive]

I wonder if there is some reason why that new system wouldn't work on the hotel portion.

 

[smerfylicious]

On the webcam, looks like they're pouring some of the good ol' grey concrete.

I'm sure it would work on the hotel portion. But, also it sounds like there's a point height-wise where this new method starts to take advantage. I would assume that with the short height of the hotel, they could just go traditional methods and probably be quicker and possibly cheaper since it's been done countless times before.

The two were connected? [Johnny Carson]I did not know that.[/Johnny Carson]

Yes, there's even a Yelp page on the tunnel:

Now mSeattle, we once had a meetup that started in the architectural-model display that was at the Rainier Square atrium, with you present, within sight of the start of this tunnel. I'm not saying you're weren't observant that day, but...

 

[mSeattle]

True. I didn't know you were there. In general I don't pay attention to malls/shopping beyond if there is or isn't proper housing or transit related to it. I thought the corridor was just for Rainier Square.

Confirmed as an Equinox Hotel.
