agree on the giant impact. It's really going to feel like the center city getting extended in a couple of directions, and I expect it to push more development NW

Very cool. Thanks!

That's a pretty lengthy write up for the Register. But those final pages (39-55) had amazing photos of the interior. That would have to be one hell of a renovation to make that place desirable for living. Crazy how they lived in the 1930's. *Back on topic*

With OCS going up, this buildings value just went way up, imo. I could see it getting a clean up and up-lighting in a couple years and just shining like a gem to all the new activity across the street.

Secanting away

I believe the larger pipes - with the single piece of rebar - are pin piles to shore up the secant wall, the smaller blue tube a link to a load cell.

Looked like the put this one in, and then took it back out

Very busy site today. It looks like there are a lot of concrete trucks, so maybe they're pouring into some of the caissons? Someone above said foundation work was supposed to end yesterday--not sure if this counts as foundation work or what.

Thank you! What exactly is a mud mat used for? To prevent the crane from sinking in the mud?

^Mud mats are temporary platforms that are used as construction aides. They can be used to provide a stable work surface or to allow for waterproofing, but they are not required structurally for the building. In this situation it is being used to provide a flat surface for the LL1 slab. In top-down construction, each below grade slab is cast on a mud mat, which is later removed from underneath during the mining operation. So the mud mat you see in the photo will eventually be removed. The next step is going to be to apply a bond breaker and then cast the LL1 slab, then there will be another bond breaker and the actual tower crane foundation supporting the 1,000' tall crane for the large tower. The tower crane foundation will also eventually be removed, leaving only the LL1 slab.

I'm so excited to see this crane go up. Is it going to be a luffing jib? Multiple cranes you say?

There will be 3 hammerhead cranes. One for each tower and a 3rd for the podium.

Someone here has to gain site access to photograph the top down construction. That would be incredible to watch the progress!
