Hi Cul.

Nice work on that spire shot. It's nearly all black in the PDF. First time I've seen it. I think the guardrail is 1100 mm above the platform or have they changed the plan ? Add up the numbers on the right side of this detail print.



I agree that it should be included in the height.

i think the aircraft beacons reach 100mm above guard rail. thus the 1.2m extra.(see diagram)
its all good.
i vote for 819m!!!! (2687feet)

So what's the consensus on the number of floors? The board says 157, some say 155, some say 156...

That floor count is complicated I am confused now too. So 1/3 of formwork is on L156 and 2/3 of formwork are on L155M? Definitly is not L157.

if i remember the fins will have an aerofoil shape and extend approx .5m from pinnacle and total 2.1m long. i also think they will be back lit.so they should look spectacular @ nite.
Also, the plans i were privelged to view were stamped FINAL DESIGN.
So i reckon we should always quote its height as 819m or 835m above slab!
cheers big ears.

Hey James, the fins are used to disrupt the air flowing past the spire as this creates vortices which produce an enormous amount of drag. The byproduct is a similar sound to trees howling in the wind, hence the info we have received advising they have been shortened to minimise this.

I bought a swedish fact book today and it says this about Burj Dubai:

Height: 643 meters. With Spire 808.

That's a huge spire!

no not when the concret end's. but were it actual doesnt have any structure around it. just the spire it's self. sticking out of the building. that would be my Def of a spire. why would you count it, if you can't see the portion that's inside of structure that's built around it.

Here's what i mean, the circle section

If a building has an "enclosed" section above roof, the official height is to top of this. eg-plant room ,dome ect. Thus the top 40 floors of spire section of Burj Dubai will be counted as height. the pinnacle starts from tier27 or 768m. so if you were to ask what is Burj dubais height without spire it would be 768m. BUT since 1996 the CTBUH have included spires with overall height ,thus official height of Burj Dubai will be 819m. ;-)
