Burj Khalifa is a megatall skyscraper in Dubai, UAE, below are some facts and introduction of the building:
Burj Khalifa, literally means Khalifa Tower. Formerly known as Burj Dubai or Dubai Tower, which was changed to Burj Khalifa when the tower officially opened on January 4th 2010. Khalifa is derived from the name of Sheikh Khalifa Bin Zayed Al
The address of Burj Khalifa is 1 Sheikh Mohammed bin Rashid Boulevard, Dubai, United Arab Emirates, the tower is located in Downtown Dubai, an area along Sheikh Zayed Road, it's one of several districts in the city that filled with lots of high-rises buildings, another district with significant amount of skyscrapers is Dubai Marina, the two districts is approximately 11 miles apart.
In comparison with Dubai Marina which located right by the sea, Burj Khalifa is 2.1 miles away from the sea, so the natural view surrounding the tower is not as tempting as Dubai Marina, but there are many man-made lakes and rivers digged around the tower, these lakes and rivers have made up for the deficiency to a certain extent.
The architectural height of Burj Khalifa is 828 meters or 2717 feet. Before 2010, Burj Khalifa's height has long been kept as a secret in order to prevent it from being surpassed by potential competitors. Finally the owner Emaar claimed the standard height of Burj Khalifa to be 828 meters, with a total height of 829.8 meters to its tip, making it the tallest building in the world in any categories. As of 2017, Burj Khalifa has hold the crown of World's Tallest Building for 8 years, it will keep the crown for another 3 to 5 years, until in 2020 or later when the Dubai Creek Tower or Jeddah Tower surpasses it.
The highest occupied floor is level 154, which is 584m high from ground. For public sightseeing, there are 3 observation decks, respectively on Level 124,125 and 148. The one on level 148 is now the world's highest observation deck at a height of 555 meters.
Mixed-use, the tower is used in a variety of purposes, respectively are Office, Residential, Hotels, Restaurant, Observation, Communication.
The 39th floor or level 39 and floors below are used as hotels or residences by Armani, from level 39 to level 108 floor are mainly used for residences. Above level 108 to level 154 are office spaces, with the exception of level 124,125 and level 148, which are the 3 separated observation decks for public sightseeing. And there's also a restaurant set at level 122, named At.mosphere.
The floors above level 154 to 163 are all mechanical floors. The number of floors is so huge as there are a total of 2909 stairs from the ground floor to 160th floor.
163 is commonly known as the number of Burj Khalifa's floors, but a 2717 foot building couldn't has only 163 floors even when the spire is removed right? That is because the floors above level 163 and below the spire are served as the base structure of spire, which is not habitable and also not for mechanical use, but it occupies 46 floors, hence technically the building has 209 floors.
Every year, fireworks show will takes place on Burj Khalifa on New Year's Eve, attracting thousands of people to watch on the scene, and millions watch online in the same time.
Design and Development:
It was the government of Dubai made the decision to build a world's tallest building, the intentions of building Burj Khalifa are various and listed below:
1. Dubai wants to make the tourism the emirate's second industry to lighten the reliance on Oil trade.
2. Building a tower that size can greatly improve the identity of city and its reputation in the world, and to capture the attention of the world.
3. Bring the title of World's Tallest Building back to Middle East as Khufu Pyramid had ever been the tallest building of the world for more than 4000 years.
4. The ruler of Dubai once said in twitter that the idea of building the Burj Khalifa was inspired by a visit to Empire State Building in New York City many decades ago in 1960s, Empire State Building was the tallest building in the world by that time, the ruler got deeply inspired by it and generated the idea of a tallest building in his homeland.
Burj Khalifa was designed by Adrian Smith from Chicago based architecture firm Skidmore, Owings & Merrill, he has also designed some other notable projects like Jin Mao Tower, Wuhan Greenland Center in China, and Jeddah Tower in Saudi Arabia, which set to become the next tallest building of the world.
The tower is built on a shamrock shaped footprint, making the tower seen like a letter 'Y' from above in the air, this shape derived from Hymenocallis, also known as desert lily, a local plant live in desert, the tower's cross section area reduces gradually as it rises.
This shape in the one hand is for the stability of the building, the Jeddah Tower which currently under construction is also based on this shape and the shape can also be found on other structures such as CN Tower, Wuhan Greenland Center and Russia Tower(cancelled). On the other hand, this sort of shape is more suitable for the hotels and residences, in which the scenery from the outdoor should be highly concerned, the Y-shape design can provide the people living in it with views to the greatest extent, that is why the lower portion that below the level 108 where the Y-shape is more apparent is used for hotels and residences and the upper portion where the Y-shape has almost transformed to circular is occupied by offices, where people working there are supposed to concentrate their focus on their work not the scenery.
Burj Khalifa was developed by Emaar Properties, a renowned local real estate firm that has also developed many other skyscrapers in Dubai and now they are working on next tallest structure of the world which temporarily named 'The Tower'.
The construction of Burj Khalifa was contracted by Samsung Construction, a subsidiary of Samsung Group, the group is best known for its electronic products and in respect of construction it had also constructed many famous buildings around the world including Petronas Towers in Kuala Lumpur and Taipei 101 Tower in Taipei.
The construction began in 2004, the building started rising in March 2005,
After that Burj Khalifa grew very fast, below is how it looked in February 2006. The building had become a 30 floor highrise building from a Y-shape base structure in less than one year.
As the building tapers into the sky, the construction becomes faster when the building built to higher floors.
As of January 2007, the tower had become an imposing supertall skyscraper that has more than one hundred floors built. And one month later it became the building with most floors on the earth.
The tower surpassed Taipei 101 to become world's tallest building in architectural height by July 2007.
In less than a month the tower surpassed Sears Tower's antenna at 527 m becoming the world's tallest building in any category, unofficially though. In September 2007 the CN Tower was surpassed by Burj Khalifa and lost its title of tallest free standing structure in the world, not officially again, as Burj Khalifa was still under construction and growing.
Although the tower had already become the tallest building and tallest structure in the world, the height of Burj Khalifa was still substantially growing.
The tower topped out in January 2009 at its full height of 829.8 meters, this is much higher than the former tallest building Taipei 101.
The whole project cost 1.5 billion dollars, the tower itself cost 1 billion dollars, it's not very high for a building with that height, even many buildings around 300 meters in American cities cost this much, this is more obvious when compared with One World Trade Center in New York City, which cost 3.9 billions dollars. But for buildings in Dubai, this number is far ahead of other supertalls while the majority of Dubai's supertall skyscrapers cost only around 300 million dollars.
