I believe the tower is actually reinforced concrete not steel

Regardless, my point is the same.

I'm starting to think this might be pushing it.

The first level has a lot more work involved as they are having to form the basin for where there will be water around the exterior most columns. I expect the level immediately following this one also to take a while because it will be the one that will be used repeatedly. Once that one is built the speed of each floor will increase dramatically.

I think the lobby has a bigger ceiling too. Its about the size of two standard floors just by looking at the renderings.

Someone posted the floor plan of one of the upper floors a while back. The core is a little bit less complex and I think the round columns turn into square columns once they get pass the first floor.

Someone earlier said they would start putting the glass on in June? I thought they did not put glass on these buildings until the frame was done? Any sort of accident would obviously damage the exterior of the building in addition to the structure itself if that were the case?

Late July is probably more realistic. Putting the facade on before the superstructure is finished is standard practice in skyscraper construction and they usually do this when the building is about 10-15 stories tall. This allows them to start working on the interior. Also, they will leave the glass unfinished where the construction elevators are.

Most of the time damage isn't an issue since most of the "heavy" construction is above them. This is the only way they can meet deadlines.

If I come back from Dallas that first weekend of August this year from my friend's bachelor party then I'll be amazed if all that is done.

Oh ok, I thought they started that when they were more like 30 to 40 floors into construction. Thanks for the info :)

Its "possible" that the building is 8-10 stories tall by August if they actually do get to a floor per week schedule by the time June comes around. They have been working on the basement level for two weeks now and they still have the western side to do. They just now put the inner formwork for the northwestern elevator core.

But keep in mind the initial work always takes the longest. Once they get the first three or four floors on I would expect one floor/week to be a reasonable assumption.

Well, I don't really know if there is a set number where they start the facade. I just threw that number out there. I would imagine the taller the building the longer they wait. Devon tower is different than most towers and it seems to like they have an ambitious construction schedule.

True

I just need to stop watching and waiting for the water to boil. LOL

Edit: Funny as soon as I said that I noticed on the webcam that they started putting up outer forms and the self-rising framework that connects inner forms to outer forms.

I remember driving home one night back in the 1980's on the Hollywood Freeway in Los Angeles during Santa Ana winds and giant windows were smashing on the freeway from the under-construction Getty Tower at Universal City right next to the freeway (around 40 stories I think)...they were popping out and smashing everywhere below and the Highway Patrol was desperately stopping traffic. There is always a danger adding many windows with open areas still present...I think. Things get windy around here as well. Would be a lesser problem on this site without a busy freeway below for them to fall onto...scads of wonderful broken emerald green coated glass was everywhere. Nice building.

True, but I wouldn't say it's too ambitious either considering a lot of Trump projects and projects in Dubai do a floor a day. Yes folks, I don't have any insider knowledge, but we'll probably see windows going on after several stories 15-30 or so I'm guessing. Definitely will start before it gets close to topping out as someone said it's the only way they can meet deadlines and Devon is being ambitious and has been ahead of schedule.

This is the Atlantic under construction in Atlanta. In this photo the building it at about half of its final height. You can see the windows are only 5 floors behind the construction..

Looks to me like there is only windows in the two center columns?

Sorry if this has already been answered before but does anyone know what this will look like after dark? How will they light it up, do they know yet? What would be the possibilities? Would be awesome if something like the vertical lit green building in Dallas?

Glass installation can lag by fewer than 10 floors as shown in this photo of Signature Place condo tower here in St. Petersburg Florida. The black mesh safety nets are visible just above the highest floor with windows installed and help protect workers installing the glass as well as the glass that is already installed below.

I am very interested in this as well. Anyone know anything in regard to this?

That's a heck of a pic. you posted West Coast. Did you take it?

Horrible zoning how? Because of the high-rise across the road from low-level apartments?

The lighting angle would be interesting to know. The shape of the building lends itself to some dramatic possibilites...hope someone is able to supply the answer.

That's a heck of a pic. you posted West Coast. Did you take it?

Sorry, I did not take the pic. The developer who built Signature Place (this condo tower is actually complete now) here in St. Petersburg kept an extensive photo gallery online during the entire construction process. It allowed out-of-town units owners to follow the progress of construction just as this wonderful site has allowed me to follow progress on the Devon tower from far away. Unfortunately, once Signature Place was completed, the construction photo gallery was removed from their site www.signaturestpete.com (http://www.signaturestpete.com/) but luckily I had saved a few of the construction pics that the developer had posted.

yes, right across the street. OMG

This is true considering the tower is 1/2 complete in that pic. it looks 'o,k,' now - but with a tower twice as tall next to low rise housing? ... And I assume this is high-rise housing. .....

Seems not to be terribly good zoning for such a suburban tract.

Because of privacy issues? That was the problem when they built 50 Penn Place and the neighborhood just to the south of 50 Penn was very upset because they felt they couldn't do anything in their backyards without being ogled by people from the tower. Is that the kind of thing you mean?

I dont know, maybe it's just me.

It seems weird to have a 60 storey skyscraper immediately across the street of 2 and 3 storey low rise residential - in an obvious suburban area. I could feel better about it if it were in a cbd or inner city built-up area. But this part doesn't appear to be - so it strikes me as odd zoning to allow such a difference in structures yet so close.

50-Penn is close to residential, but 50-Penn is NOWHERE as close to low rise residential and NOWHERE as tall as this ATL development is.

Maybe there's a plan to replace the low rise residentials with mid-rises? But it seems to me those properties are quite new - so this is why it strikes me as odd zoning.

--- maybe it is because I am in China right now and for the next 3 months .... here, in the urban areas there is QUITE a build-up of density then you will see the odd skyscraper. I can live with this, because there is density of low/mid rise and they have to put high rises somewhere (and eventually they will create a new CBD or skyscraper office park as is quite common in japan and china).

But that ATL picture shows suburban build and not urban core density. So it strikes me as an odd place to pop up a 60-storey skyscraper right across the street(s) from 2-3 storey suburban designed residentials.

First of all the Atlantic Residences as shown in the above under construction photo topped out at 40 stories, one floor higher than is shown in the picture. It also is appropriate if you take the context of what is across the other street perpendicular to the one with the mid rise residential. Next look at Atlanta's skyline in general...there are several CBD's that are so large that they almost intermingle. To be sure it is very spread out but that lends to Atlanta's dramatic skyline. Buckhead, Midtown, and Downtown Atlanta are the CBD's if you wanted to look them up. Anyway consider the context.

It looks like there working on the third and fourth tower cranes at the same time. So this must mean they will start build the main fondation of the podium soon right?

Those huge 3 boxes, are those the elevator shafts? Everything just make the whole tower look a lot smaller now.

the picture caption said Atlantic was half way, so I assumed it would top out at 60 storeys; which would be ridiculous to have in an otherwise suburban low density area (unless there is plans to change that).

and you seem to not see right across the street from this new tower that there is a low rise complex of only 2 storeys. To me, this is bad planning as it should be in more dense areas. who in their right mind would buy or rent in a suburban location that has a huge skyscraper just across the street?

ok - I bet there are many on this or other development/skyscraper oriented forums; but you understand what I am saying. This area isn't downtown and isn't in any of the aformentioned cbd's you mentioned ATL has. So it seems a little strange to me, since the low rises are also very new looking.

To each his own though, if this is what ATL wants - good for them. ... but it was just an observation to me.

Man I had a dream last night that the Tower went up 25 stories in one day.....crazy!

Those are the elevator shafts that you were referring to. They seem large but there is a great deal of floor space around them. The core areas within will also house the restrooms, and other functional service spaces, between each shaft structure. Also there are elevator banks on each side of the large boxes with a corridor in the middle. That alone might give you a better sense of the scale of this thing. It is huge.

Does anyone know the vendor who is providing the self-climbing formwork for the elevator cores? I will be excited to see that in operation as that will be a first for me. I am excited to see it in operation. These systems have been able to do a new floor of elevator core in as little as a new floor every two days! It will be more of an excercise in how fast they can tie all of the steel needed for this super large core in this building. It would explain why it is taking longer to get the core formed for the base, with the higher complexity involved. Anyone in the know I would appreciate any information that can be released. Thanks in advance and now I would love to see more detailed shots of this area to see what is going into the form work, to see if it is infact self-climbing.

Will they use concrete pumps or will they actually bucket all the concrete?

I was wondering what changed - yesterday morning traffic was even more horrendous than normal crossing Park in front of the Library. It doesn't change for pedestrians if cars are sitting there waiting to turn in.

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

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

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?

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

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.

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.

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?
