A truly mixed-use tower, Burj Khalifa comprises 1.85 million square feet of residential space, and 300,000 square feet of office space, in addition to the Armani Hotel Dubai and the Armani Residences. The tower also features lounges, health and wellness facilities, four pools and two observation decks.

Burj Khalifa's stairwell has a total
of 2,909 steps leading up to the
160th floor. Ladders are used to

Burj Khalifa comprises a
record-breaking 330,000 cubic metres
(11.6 million cubic feet) of concrete;
39,000 m/t of reinforced steel; 103,000
square metres (1.1 million square feet)
of glass; and, 15,500 square metres
(166,800 square feet) of embossed
stainless steel. It took 22 million man
hours to build the tower.
Burj Khalifa ranks #1 on all three criteria for tall buildings - height to architectural top (828 metres or 2,716.5 feet); height to highest occupied floor (over 570 metres or 1,800 feet); and, height to tip (828 metres or 2,716.5 feet).
Throughout the project,
high-compressive strength concrete
mixtures were used to withstand the
record-breaking height. Pours were
only done at night with concrete
being chilled prior to mixing and
part of the water being replaced
with shards of ice.
It took six years, from the time excavation started to the globally televised launch of Burj Khalifa on January 4, 2010.

Approximately 26,000 individually hand-cut glass panels make up the exterior cladding of Burj Khalifa, along with reflective glazing, aluminium and textured stainless steel spandrel panels and stainless steel vertical tubular fins.
All the equipment essential for the operation of Burj Khalifa are housed in seven double-storey-height mechanical floors. Located every 30 floors, they accommodate the electrical sub-stations, water tanks and pumps, and air-handling units.
Burj Khalifa's superstructure is supported by a 3.7 metres thick reinforced concrete mat. It took 12,500 cubic metres of high-density, low-permeability concrete to build the mat. A cathodic protection system under the mat helps to mitigate the effects of corrosive chemicals in the ground water.
