I'm surprised they are comfortable pouring with substantial rain 12-24 hours expected afterwards. I also have no expertise in this realm. So the concrete just cures really fast?

The temperature should allow at least the surface to cure enough to allow the rainwater to not really cause any issues. If they really feel like its gonna be a problem I'd imagine first thing tomorrow morning they will put some tarps/poly sheeting over top. It should be fine though. I mean by now it's been around 5 hours since they finished and you can already walk all over it if you wanted to; therefor rain shouldn't be an issue.

It's crazy that this is taller than the renaissance center in detroit by 3 feet.

Thx for the input. It appears they have tarped it over today.

^ That's a Manitowoc crawler crane, ie Big Red model MLC300 perhaps. Its setup for this site is one of the tallest crawler cranes I've seen downtown.

Looking at OxBlue, it's not clear to me yet where exactly the tower crane will be set. Anyone?

Yeah, my bad. But the oxblue today seems like for sure the crane is rising through the core. I could be off. Forms are going up.

A friend from Wisconsin


Just a wild guess -but could they be using an internal climber on this ?


25 to 1 ratio ?

You're right Harry. We should expect an internal climbing tower crane the core. Duh.

Still no crane parts/installation on site but I'm hoping "Big Red" moves right from here to a barge for WPS. Wishful thinking but would be a money saver, maybe?

What's risen? I have not seen any crane pieces. But this one does seem like it's dragging.

Dumb question but I only thought the core sat directly on top of the mat pour, which looks like has not happened here yet. Instead, normally does the core just sit on top of piers that are not tied into the mat?

Matt has been poured - a few weeks ago IIRC.

What a difficult site to build on, considering all the obstructions. Cheers to the developer to taking on the challenge. The foundation scope could not have been cheap!
