5 Things You Didn't Know About The Burj Khalifa

On January 4, 2010,  Dubai opened the world's tallest skyscraper, the 2,717 foot tall Burj Khalifa. This sparkling glass-and-metal building is home to a hotel, residences, and many other amenities. Here are five things you didn't know about Burj Khalifa...


It Is Twice As Tall As The Empire State Building At a height of 2,716.5 feet, the Dubai skyscraper is the world’s tallest building, surpassing Taipei’s Taipei 101, which held the record from 2004 to 2010 with a height of 1,667 feet.  The Burj Khalifa is almostthree times as tall as the Eiffel Tower and nearly twice as tall as the Empire State Building. Laid end to end, its pieces stretch over a quarter of the way around the world.

It Took 5 Years To Build The Burj Khalifa It was reported that 12,000 workers were needed each day to construct the Burj Khalifa. The high number of workers explains why it was able to be built in only five years. Excavation for the job site began in January 2004, and the project was completed in October 2009. It officially opened to the public on January 4, 2010. Adrian Smith, the architect behind the Burj Khalifa, designed the building to resemble the Spider Lily, a regional desert flower.


It Has Really Fast Elevators An incredibly tall building requires really fast elevators. The building has the longest single running elevator, which is 140 floors. The elevators at the Burj Khalifa move at 22 mph, making the elevators among the fastest in the world.  In the Burj Khalifa, the ride from the ground floor to 124th-floor observation deck is only one minute.

The Building Holds Some World Records Aside from holding the world record for being the tallest building in the world, the Burj Khalifa holds six other world records. The Burj Khalifa is also the tallest freestanding structure in the world, has the highest number of stories in the world, has the highest occupied floor in the world, has the highest outdoor observation deck in the world, has the elevator with longest travel distance in the world, and has the tallest service elevator in the world.

It Takes 3 Months To Clean All The Windows There are 26,000 glass panels glass covering the exterior of the skyscraper, and because of its great height, cleaning the windows of Burj Khalifa is definitely not a job for those who have a fear of heights. It takes an average of three months to clean all those windows, and then the workers need to start over again from scratch.
