Damn I love this building. Every building in this city should be square and bulky like this beauty.

Looks to be about a quarter of the way up - this thing is going to be really big especially if the 2nd tower is built.

We’ve definitely shared some sharply differing aesthetic assessments over the years, but I’ve very rarely agreed with anything ever so much as this.....

Floors 49-50 are amenities floors. That corner will be open space with a fire pit.


Oh, very cool....did’t realize this one would have amenity floors that high....smart move by Crescent Heights....views will be killer and a draw for prospective tenants....

Glass soon?

mind field Jan 2, 2018 3:35 PM

How many days/weeks does it take for a floor to be completed? Any rough estimate on when this tower will top out?

ardecila Jan 2, 2018 4:42 PM

There must be a problem with the glass supplier. They’re spending a lot of money to have carpenters frame out those temporary steel walls with insulation. I can’t imagine they would do that if the glass window-walls were readily available...

^^^ Exactly, either that or they are intentionally waiting for the same reasons someone mentioned in the Vista thread about the concrete compressing in very tall buildings causing a problem with the facade if they start too soon.

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.

^ Matter in fact, I feel as though many concrete structures have risen faster than in previous years. Some recent examples I've seen are the Marlowe and Essex on the Park. Have new construction methods enabled faster build outs, or am I imagining it?

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)

Flying formwork...

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

Yeah maybe the cost of temp walls is outweighed by the savings of having the concrete guys move faster. :shrug:

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.

Fvn Jan 6, 2018 8:47 PM

I wonder if the facade is gonna be like landmark west loop. That could be interesting

Bombardier Jan 6, 2018 9:45 PM

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.
