Based on three key standards, the mixed-use skyscraper known as the Burj Khalifa in Dubai, United Arab Emirates, is the tallest structure in the world.More than 28,000 handcrafted glass panels, stainless steel vertical tube fins, and aluminium and stainless steel panels make up the tower's facade.Constructed to facilitate diverse commercial, residential, and hotel endeavours, the skyscraper attained a height of 2,717 feet (828 metres) and 163 stories by meticulous maintenance throughout its construction.The tower's spiralling wings reduce in size as it rises in height, altering the structure at every level and lessening the effect of the wind on it. Reaching a height of more than 700 feet (200 metres), the tower's central core is visible at its summit.

Based on three key standards, the mixed-use skyscraper known as the Burj Khalifa in Dubai, United Arab Emirates, is the tallest structure in the world. January 4, 2010, was the official opening date of the tower. Constructed to facilitate diverse commercial, residential, and hotel endeavours, the skyscraper attained a height of 2,717 feet (828 metres) and 163 stories by meticulous maintenance throughout its construction. The Chicago architectural firm Skidmore, Owings & Merrill created the design. William F. Baker was employed as a civil engineer and Adrian Smith as an architect.A set of wings, each with its own concrete core and surrounding columns, support a central core that is hexagonal in shape. The tower's spiralling wings reduce in size as it rises in height, altering the structure at every level and lessening the effect of the wind on it. Reaching a height of more than 700 feet (200 metres), the tower's central core is visible at its summit. Using hydraulic pumps, the tower was put together and elevated to its ultimate position. A reinforced concrete mat about 13 feet (4 metres) thick, which is further supported by concrete piles with a diameter of 5 feet (1.5 metres), forms the tower's foundation. The tower is fixed in position by a three-story platform. Approximately 2,000,000 square feet (186,000 square metres) make up the two-story podium and basement area. More than 28,000 handcrafted glass panels, stainless steel vertical tube fins, and aluminium and stainless steel panels make up the tower's façade. On the 124th level is a public observation deck known as "Upstairs".
