Thanks for the info, should be interesting to watch as things progress.

Question: When a typical floor is poured, how long must it be supported from below before the forms can be removed and reused? Starting in August, they anticipate completing a new floor every 8 days. That seems to imply (assuming that there is only one set of forms) that support is only required for a few days until the floor has cured enough. I noticed that the ground floor is still being supported from below even though the ground floor was poured one month ago.

They will use a cantilever landing. This will be attached to the building and then they can wheel the form sections outside the above floor.

Whats a cantilever landing?

Platemaker--your wide angle shot from yesterday makes an excellent desktop for my computer...try it anyone who likes to fiddle with desktops. I usually have this one...

They will replace the blue forms with other forms of shoring. Just enough to keep the floor from sagging until the concrete is cured enough to post-tension it.

The tower is now the same height as the smaller parking garage.

The tower is now the same height as the smaller garage! The new garage is also open to the 10th floor and provides a great vantage point.

As always, you can find more here









Here's a great view of the post tensioned cables. If anyone is wondering how it works let me know, I found a few websites explaining it.

Awesome!!! Thank you...

[SkyWestOKC]

So what floor are they working on? (the newest forms going up)

Great pics, king. I may head out there tomorrow.

[CO-To-OKC]

Nice pictures. When is the building supposed to be completed?

[Dustin]

WOWOWOW!!! Thank you Kinggober! Amazing!

[lasomeday]

Looks like it is the 2nd floor. The first 6 floors are really tall compared to the rest of the floors. The first floor is the tallest.

It looks like the parking garage along Hudson will not have ground level business? I thought they were going to have the gym on that level and possible a retail/cafe? The floor is all bricked in and it looks like the second level may have something but you can't tell with the new mirror windows.

Kinggober...thanks for the marvelous array of photos! And thanks to all of the photojournalists for their choices of angles and locations to keep us all so well apprised of what is going on at the site. I will precede most of you into the Great Beyond and carefully help install some "stars" in your "crowns"!

Please post those links. And thanks for the great pictures!

The Devon pit is filling up fast.

From Post-Tensioning Concrete Defined - The Concrete Network
"Post tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. Afterwards, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete."

The gym will be on the third floor. I don't know about any ground level retail.

I can't believe they are pooring concrete in this rain.

[Lauri101]

I can't believe they are pooring concrete in this rain.

Yeah - and they didn't stop until the 4th or 5th bad lightning strike!

Deadlines are one thing, but to put the safety of the workers in jeopardy is ridiculous.

[OKCisOK4me]

There are way too many higher objects in downtown OKC for the workers to worry about lightning. Okay, the crane operators I can understand, but as high as they are, I'd have to imagine their cabs are grounded. Can you imagine climbing up and down those steps for several passing storms?

[JIMBO]

Looks to me like abject stupidity vs. scheduling. Stupidity won.

[metro]

Devon and MGB have a pretty good sized pond going on after today's crazy rain.

[JIMBO]

Looks to me like a case of scheduling vs common sense. Scheduling won.

[okcmomentum]

Look, they are going to have a couple pools after all.

I suspect they know exactly what they are doing and what is safe and what isn't. Generally, those who don't--do not get awarded $800-million dollar projects. Just a guess...
