Colossum Kraljevo

The building is named after the former president of the United Arab Emirates (UAE), Sheikh Khalifa bin Zayed Al Nahyan.

The hotel was supposed to open on 18 March 2010, but after several delays, it finally opened to the public on 27 April 2010. At the top, the central core emerges and is sculpted to form a finishing spire. The building was opened in 2010 as part of a new development called Downtown Dubai. The steel was shipped to Dubai after the Palace’s demolition was completed in 2008. Engineers initially considered installing the world’s first triple-deck elevators. The double-deckers are equipped with LCD displays to amuse visitors during their travel to the observation deck.

Observation Decks

{
• The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra.

• A buttressed central core and wings are used to support the height of the building.
• The Y-shaped tripartite floor geometry is designed to optimise residential and hotel space.
• The steel was shipped to Dubai after the Palace’s demolition was completed in 2008.

{

• The air conditioning system draws air from the upper floors where the air is cooler and cleaner than on the ground.

• Samsung C&T built the tower in a joint venture with BESIX from Belgium and Arabtec from the UAE.

Emaar Properties also engaged GHD, an international multidisciplinary consulting firm, to act as an independent verification and testing authority for concrete and steelwork. Burj Khalifa uses the bundled tube design of the Willis Tower, invented by Fazlur Rahman Khan. Due to its tubular system, proportionally only half the amount of steel was used in the construction, compared to the Empire State Building. Khan’s contributions to the design of tall buildings have had a profound impact on architecture and engineering. It would be difficult to find any worldwide practices in the design of tall buildings that have not been directly or indirectly influenced by his work.

Features

The foundation was designed to support the total building weight of approximately 450,000 tonnes (500,000 short tons; 440,000 long tons). This weight was then divided by the compressive strength of concrete which is 30 MPa which yielded 450 sq. A cathodic protection system is under the concrete to neutralise the sulphate and chloride-rich groundwater and prevent corrosion.

• The central pinnacle pipe weighs 350 tonnes (390 short tons; 340 long tons) and has a height of 200 m (660 ft).
• At the top, the central core emerges and is sculpted to form a finishing spire.

{

• Samples were taken from test holes drilled to a depth of 140 metres, finding weak to very weak rock all the way.

• The structure also features a cladding system which is designed to withstand Dubai’s hot summer temperatures.

• At the centre of the park is the water room, which is a series of pools and water jet fountains.

• However, in June 2016 the Shanghai Tower opened with an observation deck at a height of 561 metres, thus taking the title of the world’s highest observation deck.

• The building was opened in 2010 as part of a new development called Downtown Dubai.
• The Burj Khalifa was built primarily by workers from South Asia and East Asia.

{

• On 17 June 2008, there were about 7,500 skilled workers employed at the construction site.

• The Emaar New Year’s Eve fireworks celebration originated in 2010 with the inauguration of the world’s tallest building, Burj Khalifa.

The design is reminiscent of Frank Lloyd Wright’s vision for The Illinois, a mile-high skyscraper designed for Chicago, as well as Chicago’s Lake Point Tower. When Adrian Smith was conceiving the project at SOM, he looked out his office window toward Lake Point Tower’s curved three-wing layout and thought, “There’s the prototype”. Lucky Mister According to Strabala, Burj Khalifa was designed based on the 73 floor Tower Palace Three, an all-residential building in Seoul.

Observation deck

At the centre of the park is the water room, which is a series of pools and water jet fountains. It opened the 148th floor SKY level at 555 m (1,821 ft), giving it the highest observation deck in the world on 15 October 2014. However, in June 2016 the Shanghai Tower opened with an observation deck at a height of 561 metres, thus taking the title of the world’s highest observation deck. A 304-room Armani Hotel, the first of 4 by Armani, occupies 15 of the lower 39 floors.
