 Burj Khalifa

The Burj Khalifa[a] (known as the Burj Dubai prior to its inauguration) is a skyscraper in Dubai, United Arab Emirates.

 in the world since its topping out in 2009, surpassing Taipei 101, the previous holder of that status.[3][4]

Construction of the Burj Khalifa began in 2004, with the exterior completed five years later in 2009. The primary structure is reinforced concrete and some of the structural steel for the building originated from the Palace of the Republic in East Berlin, the former East German parliament.[5] The building was opened in 2010 as part of a new development called Downtown Dubai. It was designed to be the centerpiece of large-scale, mixed-use development. The decision to construct the building was based on the government’s decision to diversify from an oil-based economy, and for Dubai to gain international recognition.[citation needed] The building is named in honor of the former president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan.[6] Abu Dhabi and the UAE government lent Dubai money to pay its debts. The building broke numerous height records, including its designation as the tallest building in the world.

Burj Khalifa was designed by a team led by Adrian Smith of Skidmore, Owings & Merrill, the firm that designed the Sears Tower in Chicago, a previous record holder for the world’s tallest building. Hyder Consulting was chosen to be the supervising engineer with NORR Group Consultants International Limited chosen to supervise the architecture of the project. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra. The Y-shaped tripartite floor geometry is designed to optimize residential and hotel space. A buttressed central core and wings are used to support the height of the building. Although this design was derived from Tower Palace III, the Burj Khalifa’s central core houses all vertical transportation except egress stairs within each of the wings.

The structure also features a cladding system which is designed to withstand Dubai’s hot summer temperatures. It contains a total of 57 elevators and 8 escalators.
