world's tallest building (Burj Dubai)

At more than 800m and 162 floors high, the Burj Dubai has notched up a string of titles. The superscraper is currently both the tallest building and the tallest free-standing structure in the world. It boasts more stories than any other building on the planet, is home to the highest-occupied floor and has the world’s highest outdoor observation deck – situated on the gaspingly-high 124th floor.
The total weight of aluminum used in the Burj Dubai’s construction is equivalent to that of five A380 aircraft, while the total length of stainless steel bull nose fins used in the building is equal to 293 times the height of the Eiffel Tower. A staggering 58,900 cu yd of concrete was used in the tower’s construction – enough to lay a 2,065km-long pavement and equal in weight to around 110,000 elephants.
The Burj Dubai is expected to use an average of 946,000 litres of water each day. During peak cooling conditions, the tower will drink up around 12,500 tons of cooling – equal to the cooling capacity offered by about 10,000 tons of melting ice. On to electricity, and the tower will power through around 50 MVA of electricity at peak times – the equivalent of having some 500,000 100-watt lightbulbs burning at the same time.
