Hard to believe 15 months ago this area was a parking deck.

I have more pics and will have them on later!
The Tower's structural engineer confirmed the tower is only going to be 850'. They started out working on the 900+ version, then Devon reworked some things (moving the data center I assume) and asked for it to be lower. Final design was never even finished for 900+ feet. The Architect begged them to keep it that way, but Devon insisted on lowering it. The Architect really wanted his name tagged to the tallest tower in a 500 mile radius apparently hehe.
Other than that, I really only found out a bunch of technical facts and numbers about the tower. Exceptional effort was put into the basement because of the high water table and it had to be completely waterproof. Gave us details on the absolute absurdness of the mat and the HUGE forces on the tower from wind. I believe it has an overturning moment of about 4,300,000 kip-ft.
Concrete used in the first 16 floors of the building utilize 12ksi concrete. This is the first time 12 ksi concrete has been poured in Oklahoma ever. Dolese actually agreed to release their mix design. 10 and 12 ksi concrete are 50% portland cement (rofl crazy), 30% slag, 20% fly ash. The mat concrete, which was 7 ksi, was 50% portland cement and 50% fly ash with TONS of chemical admixtures to get it as workable as it was.
The Tower's period is 6.4 seconds with a total drift of 18". Overall, it's a pretty stiff tower. It had to be because of the curtain wall design. (kind of interesting)
I think that's probably all that is interesting to you guys. The rest was just a lot of info on the columns, beams and walls.
He did mention that the crown was going to be lit up someway, but he didn't know anything about that.
18"! That is barely moving. Did they say what kind of wind it would take to snap it in half?
China announced it is build a Dubai replica.
An update on my distant observation spot by Quail Springs Mall. It has passed OK Tower and at night just glows from the lights inside. The crane to the west seems to have gone up, the east crane will need pushed up soon. From my view it looks like the west crane is about the height of the Chase tower. Caught an image just now from the cam of a window pane being installed on the north side, I'll post it below.
My friend working with the Devon Tower (Flintco side) just posted this photo from about the 20 floor looking out: http://www.flickr.com/photos/30796964@N02/5333503857/
^^Nice pic!I wish we had pics from The crane operators pov,now that would be an awesome angle!
whatever happened to the link for the state cams on ksbi tv's website? it used to be in the top right corner of the homepage, but it's no longer there and i can't find a link to the northwest expressway cam anywhere on the site.
"4,300,000 kip-ft" to tip it over. It wouldn't ever snap in half. I have no desire to do the math right now to find out what wind speed that would resist. I don't have the dimensions to the building to even do just a simple estimate. Also, that number is from the wind tunnel test. So it's actually designed to resist more than that.
I think we can all agree the building isn't going anywhere.
What is kip-ft?
thanks pete! is the link now in a different spot on the homepage?
I don't if they moved the link because I just had it saved directly.
Here's another webcam from the Bricktown area:

East Tower Crane going up right now.
The unit Kip refers to a 1000 pounds of a force acting on an object. In this case the tower. These Kips (Loads) acting on the tower both vertically (Gravity type loads) and laterally (horizontally). Kip-ft is typically used as a measure of moment on an object. (kind of as an example the force acting on a brick standing on end that results in its tipping over). Hope this helps somewhat.
Thanks for sharing that.
