The Burj Khalifa's construction began in 2004, with the exterior finished five years later in 2009. The height of the building is 828 m (2793 ft), making it the tallest skyscraper in the world.
The design process for the tower was long and complex, with many different designs being considered before it was decided to use a hybrid design: a vertical structure with no central supporting pillar at the top offering maximum floor space; however, there are eight smaller pillars instead. The total cost of the project was estimated to be $750 million at the time of its completion.
It took more than 700,000 m3 of concrete to build the tower, which is the equivalent of constructing a 32-storey building with 5 meters of concrete per floor. The observation deck has a radius of 456 m, making it the largest by far (in terms of distance from the center) of any existing tower. It also has the highest visitor volume of any observatory deck in the world.
The building is owned and operated by Dubai Properties, a government-owned company that manages real estate projects throughout the UAE. It was designed by Fumihiko Maki, who also designed the Tokyo Tower.
Burj Khalifa construction began on January 6, 2004. The original design called for the creation of a skyscraper with 112 floors and a height of 828 m (2743 ft). However, after eight years and three months of construction, it was reported in 2011 that the tower was still not complete.
At least 57 people have died while working on the project so far. According to the New York Times, this number may be higher because many workers risk their lives without any protection from falling debris or other hazards.
When it was completed in 2009, Burj Khalifa broke the previous record held by another Dubai skyscraper, the Palm Jumeirah. It is also the most expensive residential building in history, costing $1 billion to construct.
Burj Khalifa has 104 floors above ground and it is the first skyscraper to include a helipad on its roof.
Burj Khalifa, the world's tallest structure, took six years to build and was inaugurated on January 4, 2010. The building is 828 meters tall, and the entire system is made of reinforced concrete towers. It contains more than 5 million square feet (480,000 m2) of floor space, which amounts to about 1.5 times the size of Manhattan.
The main body of the building is considered a shell structure because most of it is made up of light frames with glass panels in the walls and roof. The heavy duty aluminum spires that stick out from the top are actually the only parts of the building that are not hollow. They contain elevators, cameras, lighting systems, and other amenities for the building's residents. The rest of the building is just open space - apart from one small private apartment unit at the very top.
All in all, the building is about 70 percent empty space. This is because most of the rooms lie above the first four floors, so they can be used for office spaces, hotel rooms, etc. Only the top floor has all its rooms on ground level.
There are also several smaller buildings attached to the main structure, some of them completed earlier than the main part of the project.
The construction of Burj Khalifa was initiated in 2004 and ended in 2009, and it was opened to the public a year later. For Dubai Creek Tower, construction started in 2016 and it will be completed before Expo 2020. The construction cost of Burj Khalifa was $1.5B, whereas it was $1.1B for Dubai Creek Tower.
Burj Khalifa is the tallest building in the world. It has 828 m (2743 ft) with the observation deck at 829 m (2693 ft). Its height makes it more than twice as high as the previous record holder, the 708-m-high (2328-ft-) Sears Tower in Chicago. The volume of Burj Khalifa is about 5 million square feet (460,000 m²), which is almost as large as the entire city center of London.
Dubai Creek Tower will be the second-highest building in the world when it is completed. At 233 m (764 ft) tall, it will be 10 m (33 ft) taller than the current leader, the Shimizu Corporation's 234-m-tall (768-ft-tall) Vauxhall Bridge Road Office Building in London. The volume of Dubai Creek Tower will be nearly double the size of Burj Khalifa.
The two buildings are not only different in height but also in other aspects such as design and function as well.
The Burj Khalifa /Began operations on January 4, 2010
Burj Khalifa ("Khalifa Tower"), known as Burj Dubai during construction, was formally named after the ruler of the neighboring emirate of Abu Dhabi, Sheikh Khalifa ibn Zayed Al Nahyan. Although the skyscraper was publicly inaugurated on January 4, 2010, the inside has not yet been completed.
In terms of design, the building is one of the most distinctive in the world. The spire of the Burj Khalifa is comprised of around 3500 tons of structural steel. This is where the communication equipment is stored. The antenna weighs about 4500 tons and is made of aluminum. It is the largest in the world by far.
The height of the tower has been criticized because it blocks out much of the view from Downtown Dubai. It was also reported to have caused problems with air traffic in the city center.
The building was designed by BKSH Architecture + Planning and developed by Brookfield Properties. It was built by Al Jaber Company at a cost of $750 million. The project was launched in 2004 and completed in 2010. The building's gross floor area is.
There are more than 50 stories above ground level and about 2 miles down inside the core of the earth. The total weight of the structure has been estimated to be about 825,000 tons. That makes it the tallest free-standing structure in the world.
The building's height has been criticized because it blocks out much of the view from Downtown Dubai.
The construction of the tower has been associated with many accidents.
