Burj Khalifa 

At the peak of construction, 12,000 workers worked on the building per day.

The weight of the concrete is equivalent to 100,000 elephants. The total weight of aluminum used on the Burj Khalifa is equivalent to that of five A380 aircraft.  

The Burj Khalifa elevator speed is 10 meters per second, making the elevators among the fastest in the world. 

It was designed by the Chicago-based architectural firm of Skidmore, Owings & Merrill. Adrian Smith served as architect, and William F. Baker served as structural engineer.

Among its many other architectural achievements, the firm can be credited with designing One World Trade Center in New York City.                                                                                                                                               The Burj Khalifa was built to house a variety of commercial, residential, and hospitality ventures. These include a hotel and luxury residences designed by Italian fashion designer Giorgio Armani, in addition to office space, observation decks, restaurants, and health facilities.
