the highest concrete reaches in borj-e Milad is only 315m. the top is steel antennea.
even the 540m Ostankino tower in Moscow , its concrete reaches just 385m.
so above 400m is a rarity atm.


the 468m oriental pearl tower concrete section reaches 350m. does anyone know if part of 118m antenna is concrete? looks like it.

even the 492m SWFc has concrete core that stops at 440m. Taipei 101 roof is 448m is this concrete?
ICC top concrete reaches 470m.
cheers

[QUOTE=STR] It consists the up to different heights of different sketch forms is enough. [Note: I didn't even try to correct that one] [QUOTE]

i dont speak much german, but im guessing sketch forms is a mistranslation of setbacks

lol i am sure they wont cover the building with that green.

Yes it is rare to pump concrete above 400m because there isnt a strong enough equipement that is also affordable to pump concrete above 400m.

They made new technology for pumping concrete above 575m for the Burj since the Burj is a wholly unique project and of course will be renown for its ground breaking architecture. There is an article about it somewhere in these forums...

He's a member and he does the same (pointless IMO) ranting as you do, but on political/religion/social discussions.

DOKA says that the core has 180 steps, while the number of floors is 1??. They were listing 4 different heights for the floors and we know that some of them are duplexes or so called double height.

I consider the number of steps on the core, a more correct way to categorise the "number" of floors in abuilding, so maybe that 189 quoted was not wrong afterall.

Maybe 180 is the number of times the core building system is raised. It appears to rise once for each floor though, so it doesn't make much sense that it's so far out... unless there's a lot of double height floors? There's obviously about 4 or 5, but not 10?
I'm still hoping there's going to be 40 steel floors (even if not all occupied) above the 156? concrete ones.
Maybe we'll have to wait for Al Burj ? / The Tower to be up near 200 floors?
I think that building in Hong Kong with 110? floors will be No.2 in terms of floor count. The Twin Towers had 110 didn't they and Sears 102 if I'm not mistaken. Taipei 101 (of course) and Petronas "only" 90 (despite it's height).

Are elevators going to be going up until the last floor or will they stop at a point and then will have to change to get higher? Have they also developed an elevator that will go from the ground floor up until the top floor?

While thank you for your nice comments. Much appreciated!

i also think there will be some sort of floors above 162.maybe 27 of them which will total 189? 27x 3.6m=97m ,thus 625m + 97m=approx 722m.the base of spire will be about 720-40m, so it works out.
but the top 27 will be light weight steel framed.for communications equipment? maintenance platforms for spire structure above? they will be "floors" or levels but not inhabitable. im guessing atm?
as for most numbder of floors, the one in Hong Kong-ICC does have 118 floors but every floor with number 4 in it have been omitted, thus 12 floors are missing,thus 106 and they include 4 basements, thus 102 above grd.
Sears has 108 above grd.

I would be suprised if EMAAR hasn't got any suprises for us, like the constructors of Chryler had!But i also hope it won't be shorter as we all anticipate!

Question,

How many people will occupy the tower when it's finished?

Not only the residents but also the number of people that will be working and staying in the hotel. bassicly how many people will be inside the building on a normal day.

^I'd guess around 5,000, not including vistors. There will probably be around 20,000 vistors a day.

Not that many I think, maybe a few thousand but certainly not 50,000 like the WTC

I am also thinking around those lines Culwulla. I think BD will go higher above the concrete core and below the spire than what STR is projecting. Remember here the operative words "I think" and not that I know.

What I do know for sure is that only those who are the final decision makers know how high they will really go as this is consistent with the overall secrecy of BD's height for years now.

The final figures will be what they will be WHEN they will be.

The WTC was a 10Mgsqft office, hotel and retail complex, with ~50,000 permanent occupants. That translates into 1 occupant per 200sqft.

The Sears Tower, a 4.5Mgsqft office tower with limited retail, has roughly 22,000 occupants, also in the 200sqft per occupant.

A quick breakdown of the use goes below:
Hotel:
172 Guest rooms
486 Hotel condos
658 Total rooms
1,316 occupants with two people per room

585 residential units
1,316 occupants with an average of 2.25 occupants per room.

Offices will have, as reported, roughly 600 occupants.

1,316+1,316+600=3,232.

I was a bit off.

Thanks STR

3,232 is not much compared with other towers, but it will be easier to evacuate the building in case of an emergency.

^Yes and no. There will be fewer people, but there will also be fewer stairwells. According to the leaked plans, most of the building will have only two stairwells. The upper floors will only have one.

Someone I know has seen and have in his office the hard copy plans for the top steel structure, before the redesign. I'm trying to get my hands on them, since it seams that are not confidential.

Will see.
