The Burj Khalifa (Arabic: ??? ?????, Arabic pronunciation: [b?rd?? xa?li?fa]; pronounced English: ), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m (2,722 feet, just over half a mile) and a roof height (excluding antenna, but such as a 244 m spire) of 828 m (2,717 feet ), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009 (preceded by Taipei 101).Construction of the Burj Khalifa began in 2004, with the exterior finished five decades later in 2009. The principal structure is reinforced concrete. The building was opened in 2010 as part of a new development called Downtown Dubai. It is designed to be the centrepiece of large-scale, mixed-use development. The decision to construct the building relies on the government's decision to diversify from an oil-based economy, and for Dubai to obtain international recognition. The building was originally named Burj Dubai but was renamed in honour of the ruler of Abu Dhabi and president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan; 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 Adrian Smith, of Skidmore, Owings & Merrill, whose firm designed the Willis Tower and One World Trade Center. Hyder Consulting was selected to be the supervising engineer with NORR Group Consultants International Limited selected to supervise the architecture of this project. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra.
