Construction Highlights
Burj Khalifa is truly the product of international
collaboration; over 60 consulants including 30 on-site
contracting companies from around the world were
involved in the project.
At the peak of construction, over 12,000 professionals and
skilled workers from more than 100 countries were on site
every day. The world's fastest high-capacity construction
hoists, with a speed of up to 2 meters/sec (6.5 feet/sec)
(120 meters/min), were used to move men and materials.
Over 45,000 cubic meters (1.59 million cubic feet) of
concrete, weighing more than 110,000 tons, were used
to construct the concrete and steel foundations, which
feature 192 piles, buried more than 50 meters (164 feet)
deep. Burj Khalifa employs a record-breaking 330,000
cubic meters (11.6 million cubic feet) of concrete; 39,000
m/t of reinforced steel; 103,000 square meters (1.1 million
square feet) of glass; 15,500 square meters. (166,800 square
feet) of embossed stainless steel; and the tower took
22 million man-hours to build.
The amount of reinforced steel used at the tower, would if
laid end to end extend over a quarter of the way around
the world. The concrete used is equivalent to a sidewalk
1,900 kilometers (1,200 miles) in length, and the weight
of 110,000 elephants. The weight of the empty building
is 500,000 tons.
The tower accomplished a world record for the highest
installation of an aluminum and glass facade, at a height
of 512 meters (1,679.8 feet). The total weight of aluminum
used on Burj Khalifa is equivalent to that of five A380
aircraft, and the total length of stainless steel 'bull nose'
fins is 293 times the height of the Eiffel Tower in Paris.
