A dazzling fireworks display marked the inauguration of the world’s tallest building, Burj Khalifa (formerly known as Burj Dubai) in downtown Dubai. Burj Khalifa opened its doors to the public who rode Otis double-deck elevators to “At the Top, ” the 124th floor observation deck. At 828 meters high and more than 160 stories, Burj Khalifa is 319 meters taller than the previous record-holder Taipei 101.
The official inauguration of the tower took place in the evening where the height of the tower was finally revealed: 828 meters (2,717 feet) high and more than 160 stories, making it 319 meters (1,047 feet) taller than the previous record-holder Taipei 101.
The tower – a construction and engineering marvel – is the centerpiece of downtown Dubai, one of the seven emirates of the United Arab Emirates (UAE). Burj Khalifa features 900 apartment residences; 144 residences in the Armani Residences Dubai; many fine-dining and entertainment venues; 49 floors of corporate office suites; the world’s first Armani Hotel; a four-story fitness and recreation complex; and an 11 hectare (27 acre) park with six water features.
For more than five years, thousands of Otis employees from around the world have been involved with the Burj Khalifa project, from the early negotiation stages to the design, engineering, installation and project management phases. Otis has supplied and installed eight escalators and 57 elevators, including 25 energy-efficient Gen2® machine-roomless units and seven SKYWAY® systems, of which, two are double-deck elevators used exclusively for travel to the observation deck. The tower also boasts an Otis elevator with the longest travel distance in the world at 504 meters (1, 654 feet), the world’s highest elevator landing at 638 meters (2, 093 feet) and the world’s fastest double-deck elevators at 10 meters per second (1, 969 feet per minute).
