Burj Khalifa known as Burj Dubai prior to its inauguration is the world’s tallest manmade structure standing at 829.84 m (2,723 ft). It is the centerpiece of Dubai’s most prestigious 2 km2 (490-acre) flagship urban development, entitled Downtown Dubai.
The Arabic meaning for the word Burj is ‘tower’, which gives Burj Dubai a meaning of ‘Khalifa Tower’or ‘Tower of Khalifa’. Its its design was influenced by the six petal desert flower.
Burj Khalifa is surrounded by a man-made lake and a combination of residential, commercial, hotel, entertainment and leisure outlets, along with open green spaces, water features, and pedestrian boulevards.
The total cost for the project was about US$1.5 billion; and for the entire “Downtown Dubai” development, US$20 billion.
- The triple-lobed footprint of the building is based on an abstracted desert flower native to the region.
- A subtle reference to the onion domes of Islamic architecture can be found in the building’s silhouette when looking up at the lobes from near the base.
- The tower is situated on a man-made lake which is designed to wrap around the tower and provides dramatic views of it.
- Engineers working on the design considered installing triple-decker elevators, which would have been the first in the world. The realized building will use double-decker elevators.
- The top of the building contains a public observation deck and a private club above that.
- Although the building’s shape resembles the bundled tube concept of the Sears Tower, it is structurally very different and is technically not a tube structure.
- The design by Skidmore Owings & Merrill replaces a plan to reuse the design for Grollo Tower, which was proposed in Melbourne a few years earlier.
- Designed by Adrian D. Smith, FAIA, RIBA Design Partner at Skidmore Owings & Merrill LLP.
- “Burj” is Arabic for “Tower”.
- Burj Khalifa became the world’s tallest building, along with the world’s tallest man-made structure when it is was opened on 4th January 2010.
- The total height of Burj Khalifa is 829.84 m (2,723 ft).
- The highest residential floor is on level 109.
- An observation deck occupies the 124th floor.
- The building was rotated 120 degrees to allow for less stress from the prevailing winds.
- The foundation piles are 150 ft. deep.
- The building sits on a concrete and steel podium with 192 piles descending to a depth of more than 50 metres (164 feet).
- A total of 45,000 cubic metres of concrete have been used in the foundations with a weight in excess of 110,000 tonnes.
- The exterior cladding is of reflective glazing with aluminium and textured stainless steel spandrel panels with vertical tubular fins of stainless steel.
- The cladding system is designed to withstand Dubai’s extreme summer temperatures.
