I don't know how in the world you people can tell this stuff at this distance!

Well, just by looking at ndmoore photos there are outside forms on at least 2 sides and they built a work platform on top.

[OKC@heart]

The northeast core looks like its about ready for a concrete pour.

Plus the concrete pumper pouring concrete into the formwork on the Northeast core supports that statement! lol!

[OKC@heart]

FYI - on this job the outside forms will be crane lifted - only the inside forms will be self-lifted.

Forming Concepts, Inc. (FCI) - Concrete Forming Systems and Accessories

I was wondering how they were going to do that with all the custom shapes involved with the corners and such. So that will add to the time in floor to floor rate of assembly and pouring correct?

There you go Concrete evidence.

They spent so much time on the first floor. When should they start the second one? And one more thing who works on the construction site?

The concrete will be pumped both in the elevator cores and for the decks. The pump will be on the ground but a placing boom that extends out will be placed on one of the elevator core decks and will be raised with the self rising form system. Only the inside forms will self raise. The outside forms will be crane handled. There is three inside core forms and only one outside set of forms. How fast the building goes up will be determined by how fast the decks can be formed and poured. the elevator cores could easily outrun the decks in speed. The first few floors are usually the slowest to complete. Assembling forms getting equipment to the site and learning curves all take their toll. One core will be poured tomorrow as I understand it. the Trulift self rising forms system will be computer controlled and be positioned by six laser sensors in each core. It has the capacity to lift about 1/3 of a million pounds per core and there are three.
The self rising picture and video posted earlier from Doka is our European competitor. They lost this order. We are a total USA company. The video we posted was done by our Middle East sales operations.

Thank you.

Here's a random question where will they keep those external forms? On the deck or on the ground. It seems like that would affect speed.

If there were three sets of outside forms it would have been a problem because the forms would have been trapped under the deck forms at some point. Because there is only one set of outside forms they will be moved from one core to another and spiral up the building. The outside form will be used at all times.This method keeps the forms from being trapped without the need to lower the forms to the ground which on a high building is time consuming. These methods and ideas are the secrets to high rise construction building.
The first core was poured last night.

You POUR beer. You PLACE concrete.

You POUR beer. You PLACE concrete.

Then somebody better tell the guys at the concrete company because they said the foundation would be made with one continuous 'pour', not one continuous 'place'. They even had a 'pouring' party not a 'placing' party. However, I did read where they 'place' rebar.

More than 26 million pounds of concrete will be poured into the base of the new Devon Energy tower on Sunday — a job that will require 45 cement trucks doing a continuous pour for 15 hours.

I took some photos of the Devon construction yesterday...

Here are Casey's photos

[warreng88]

After the Arts Festival, are they just going to shut down Reno completely so they can work on the north part of the Myriad Gardens and the Devon Tower simultaneously?

[hipsterdoofus]

Anyone take any pics from the west lately? Kind of curious how the west side of the garage is looking.

[Dar405301]

nice shots! when were the 2 newest cranes assembled? i was in okc this past weekend, and even went to the site, and at that time, there were only the 2 original tower cranes there. and, what are the 2 newer ones going to be used for? the podium?

Last weekend. They will be used for the podium.

In Casey's last picture is that a tunnel near the western most crane? If it is where does lead to?

[Insider]

In Kinggober's last picture is that a tunnel near the western most crane? If it is where does lead to?

Yes, it is a tunnel. We (some coworkers and I) believe it will lead to the stage that they are constructing so they will be able to move things back and forth from the building to the stage out of sight...

Pictures from lunch today from the Devon garage Awesome place to see the entire south side of the project.

I was thinking the same thing on the tunnel after we noticed it today.

Looks like they started moving the outside forms to another core today. They should be done by the end of the day at the rate their going.
