The Height
  • The towers's spire is visible from 6 miles away and you can see Iran (50 miles away) from the 124th floor observation deck which is open to public
  • This building is so tall that the temp at the top is 10c cooler than at the bottom
The Interior
  • Restaurant is on the 122nd floor, gym on the 123rd floor and a nightclub (wht the heck dubai) on the 143rd. Offices soars up to the 160th floor. There are plans for a mosque on the 158th (what?! only plan? LOL, nightclub already have)
  • The air conditioning is the equivalent of melting 12500 tons of ice per day (*_*)
  • The water systems will supply 250000 gallons of desalinated water per day.
The Construction
  • Tower has been built using eight millions cubic feet of concrete, 31000 tons of reinforcing steel, 167000 sq ft of stainless steel cladding, and 1.1m sq ft of double-glazing.
  • The hexagonal concrete core of the tower houses all of its 57 lifts. It is mounted on 3 wings, arranged in a 'Y' shaped to distribute its weight, making its more stable
  • The last piece of Burj Khalifa which is about 260m is finished by Malaysian steel company, Eversendai Corporation Sdn. Bhd \(^_^)/
The Lifts
  • A set of double deck lifts carry visitors to the tower's observation deck, on the 124th floor.
  • If all the lifts break down, there are 3000 stairs from the bottom to top..LOL
The Structure
  • The tower is so big it has already sunk 2.4 inches into the ground. Its foundation are 150ft deep
  • It has been designed to sway up to 6ft in high winds. The sun's heat makes it lean as much as 3ft as the metal expands and contract.
  • The rods that reinforced the structure weight 31400 tons. Laid end to end they would stretch more than a quarter of the way around the world.
  • The external surface is the size of 17 football fields..Haiyo!
P/S : I know my english is bad isn't it. (~_~) sigh...I'll learn, hehe :p
