It is the tallest structure in the world, standing at 829.8 m (2,722 ft).[4][9] Construction of the Burj Khalifa began in 2004, with the exterior completed 5 years later in 2009. The primary 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 build the building is reportedly based on the government's decision to diversify from an oil-based economy, and for Dubai to gain international recognition. The building was named 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 tower in the world. Burj Khalifa was designed by Adrian Smith, then of Skidmore, Owings & Merrill (SOM), whose firm designed the Willis Tower and One World Trade Center. 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 of Burj Khalifa is derived from patterning systems embodied in Islamic architecture, incorporating cultural and historical elements particular to the region, such as in the Great Mosque of Samarra. The Y-shaped plan is designed for residential and hotel usage. A buttressed core structural system is used to support the height of the building, and the cladding system is designed to withstand Dubai's summer temperatures. It contains a total of 57 elevators and 8 escalators. Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, the labour issues during construction were controversial, since the building was built primarily by workers from South East Asia, who were allegedly treated poorly. Bringing Burj Khalifa to life required a combination of visionary ideals and solid science. In the process, the project amassed an awe-inspiring number of facts, figures, and statistics. World Records At over 828 metres (2,716.5 feet) and more than 160 stories, Burj Khalifa holds the following records: 360 of enjoyment Tallest building in the world Tallest free-standing structure in the world Highest number of stories in the world Highest occupied floor in the world Highest outdoor observation deck in the world Elevator with the longest travel distance in the world Tallest service elevator in the world Tallest of the Supertall World coldest place https://youtu.be/NffdPMEHEBk Burj Khalifa 124th Floor https://youtu.be/644Na_xOkKs FACEBOOK ID https://www.facebook.com/zsk477 FACEBOOK PAGE https://www.facebook.com/M-Burhan-Manzar-162692810608233/ GOOGLE PLUS https://plus.google.com/u/0/ Email zsk477@gmail.com If you like my effort, please like my channel.
