one grant park is utilizing tables which make it easier to do a floor because you can shave a day off of the process by basically pre-assembling the decking in big pieces (which is what tables are)
they are just pulled out from the previously poured floor, placed on the newly poured floor and then sealed, and then ready for the rebar/utilities

also generally a good deck cycle is 3 to 5 days (im not sure about OGP's cycle though)

Essex is a fairly slender building with minimal parking, so things go faster.

Another thing to consider is how quickly this building has flown upwards since they dodged the parking structure slowdown. It's possibly they are outrunning the schedule and the glass supplier just was never scheduled to start until early this year.
Yeah maybe the cost of temp walls is outweighed by the savings of having the concrete guys move faster.

Have we seen a facade mockup on this one? I think it's just an off-the-shelf window wall system, it's not a fancy curtain wall or something with custom extrusions and details.

A 3-day pour cycle is pretty common for an average size flat floor plate (say 10k sf - 15k sf) with either table (like OGP) or traditional framing techniques (like Essex and Marlowe). This has been pretty consistent since the last boom in the early 2000's. If floor plates get larger like the 22k sf plate at Block 37, or if they have complicated geometry like Aqua or 465 N Park, or if they have parking ramps, then the cycle time is increased for the added complexity.

Heard the glazing contractor that McHugh hired just booted them from the job last week.

Is it bad that I feel sorry for smaller cities that this behemoth would dominate their skyline but its just a bookend to ours? Nah....I love it.

It will barely crack into the top 10 tallest when it (and Vista) is completed. I don't feel bad about that one bit
