Standing about 830m tall, Burj Khalifa, earlier known as Burj Dubai, is not only the tallest building in the world but also the tallest man-made structure in the world. It is a mixed-use type building built by Emaar Properties at a cost of $1.5 billion approx.
The building boasts of 163 habitable floors and a floor area of little over 0.3 million square meter. The gigantic structure is said to have consumed a staggering 330,000 cu.m. of concrete and 55,000 tonnes of steel. The superstructure rests on a massive 3.7m thick raft which in turn is supported by 192 reinforced cement concrete bored piles of 43m length each.
Some other interesting facts about this marvel are:
It hosts the world’s longest distance traveling elevator besides the tallest service elevator.
It hosts a total of 57 elevators and 8 escalators.
Among hosts of other records, it also created the world record of vertical pumping for any structure when concrete pumping for it’s 156th floor was being done.
At the peak of work, some 12,000 workers were engaged daily.
Now, if that’s no mean structure sneering at you then just wait for this one named the ” Kingdom Tower ” to show up in the skyline of Jeddah in Saudi Arabia. That colossal one would to extend more than a kilometer over the ground, if reports floating around are to be taken at face value. Until then Burj Khalifa will continue to rule the horizon.
