The world’s tallest building, Burj Khalifa rises a half mile into the desert sky. In its design, this miracle of modern engineering also honors ancient Islamic architecture like the Great Mosque of Samarra. To take people to the top, Otis created what are among the world’s fastest double-deck elevators.
It’s so tall that people can see the sun set twice in the same evening from Burj Khalifa – first from the lower floors and then again from “At the Top,” a series of observation decks on floors 124, 125 and 148.
To disrupt air flow, architects created a series of setbacks on each of the tower’s three wings. The tapered, irregular shape minimizes wind forces and reduces the tower’s lateral movement. At its tallest point, the tower sways 1.5 meters, nearly 5 feet.
For the tower’s triple-lobed footprint, architect Adrian Smith drew inspiration from the Hymenocallis (spider lily), a tropical flower cultivated in the desert climate for its exotic beauty. The motif occurs throughout the building’s interior.
The mixed-use tower includes 1.85 million square feet of residential space, another 300,000 for offices, with plenty of room for luxury hotels, fine restaurants and four swimming pools.
The tower has more than 24,000 windows – nearly 1.3 million square feet of glass. To keep it clean, 36 fearless souls use old-fashioned squeegees and soapy water, working from 13-ton high-tech machines that move along tracks on the building’s exterior.
In 2015 the two double-deck elevators to the observation decks on floors 124 and 125 reached an impressive milestone, having traveled a total of 384,400 kilometers since the building’s opening in 2010 – equal to the distance between the Earth and the moon.
Otis programmed certain elevators for controlled evacuation in case of emergency, the first ever installed in a megatall building.
You can take the stairs if you want. It’s precisely 2,909 steps to reach the 160th floor.
Among its many records, Burj Khalifa features the world’s longest elevator shaft, spanning 140 floors and used by the Otis service elevator.
Emaar Properties wanted to honor the city of Dubai with a building that combined art, engineering and meticulous craftsmanship on an unprecedented scale. We’re proud they trusted Otis to help achieve that vision.
In designing the tower’s vertical transportation system, Otis engineered the world’s fastest double-deck elevators. They reach the observation decks on floors 124 and 125 in just 60 seconds, traveling at 10 meters per second.
Otis technicians are on-site around the clock to keep the tower’s elevators and escalators operating at peak efficiency. Our EMS Panorama® technology continuously monitors every aspect of the system’s performance, feeding information to displays in the control room.
"Our experts have created a state-of-the-art, superfast system for Burj Khalifa. How else would you get to the world’s highest fine dining room?"
