Burj Khalifa-Dubai

Bringing Burj Khalifa to life required a combination of visionary ideals and solid science. In the process, the project amassed an awe-inspiring number of facts, figures, and statistics.

At 828 meters (2,716.5 feet) tall, Burj Khalifa is 3 times as tall as Eiffel Tower and twice as tall as the Empire State Building. Burj Khalifa holds the world Records on: tallest freestanding structure in the world, highest number of stories in the world, highest occupied floor in the world, highest outdoor observation deck in the world, elevator with longest travel distance in the world, and tallest service elevator in the world.It is said that the weight of concrete used to build the skyscraper is equivalent to 100,000 elephants and the steel used to construct the frame is equal to that of 5 Airbus 380 air crafts.

The building design takes after the Greek flower, Hymenocallis. The name is translated as Beautiful Membrane in Greek.The building was constructed by a South Korean Company called South Korean company, Samsung Engineering and Construction. Burj Khalifa was built at a cost of $1.5 billion, It is supplied with about 250,000 gallons of water daily, and its electricity needs can go up to 360,000 100-watt bulbs burning at once.During the peak of construction, at least 12,000 workers worked on the construction site per day.The tip of the sphere of Burj Khalifa can be seen from 95 kilometers away.The tower was to be called Burj Dubai but this was changed at the last minute to honor Sheik Khalifa bin Zayed al Nahyan, the ruler of Abu Dhabi for bailing out Dubai's bankrupt sovereign wealth fund with a $10 billion in 2009.Burj Khalifa has 54 elevators which have a speed of up to 40 miles per hour.

Here's a factoid that will blow your mind that you can see two sunsets in a day there. The Burj Khalifa is so tall that you can watch the sunset from the base of the building, get into an elevator right to the top, and watch the sunset all over again.In fact, if you are a Muslim living on top of the Burj Khalifa, you will have to fast longer during Ramadan because of this time difference: about three minutes between the time of the sunset on the ground and the sunset on the top.
