Burj Khalifa Dubaï (33)
Burj Khalifa est la plus grande tour du monde (en arabe : برج خليفة, tour de Khalifa). Appelée Burj Dubaï jusqu’à son inauguration, c'est un gratte-ciel situé à Dubaï aux Émirats arabes unis, devenu en mai 2009 la plus haute structure humaine jamais construite. Sa hauteur finale, atteinte le 17 janvier 2009, est de 828 mètres. Elle doit former le cœur d’un nouveau quartier : Downtown Burj Khalifa. Son inauguration et ouverture partielle ont eu lieu le 4 janvier 2010.
À noter que celle-ci sera dépassée par la Kingdom Tower de Djeddah en Arabie saoudite d'ici 2018.
Burj Khalifa fait partie d’un vaste projet urbanistique, immobilier et architectural couvrant une superficie de 2 km2. Il s’agit de créer un nouveau quartier, Downtown Burj Khalifa, un peu au sud du centre historique de Dubaï, et à côté du quartier côtier de Jumeirah (en), mais situé quelques kilomètres à l’intérieur des terres. Ce quartier doit comprendre, outre le gratte-ciel du même nom, un lac artificiel et de nombreux bâtiments de grandes dimensions. En tout, il prévoit un ensemble de 30 000 résidences, neuf hôtels dont The Address Downtown Burj Dubaï achevé en 2008, au moins 19 tours résidentielles, le plus grand centre commercial du monde, le Dubaï Mall qui y a ouvert ses portes en 2008, trois hectares de parcs et le lac artificiel de douze hectares (Lac de Burj Khalifa). Sur ce dernier, la fontaine de Dubaï offre un spectacle aquatique.
Burj Khalifa (Arabic: برج خليفة, "Khalifa Tower", pronounced English /ˈbɜːrdʒ kəˈliːfə/), known as Burj Dubai before its inauguration, is a megatall skyscraper in Dubai, United Arab Emirates. It is the tallest artificial structure in the world, standing at 829.8 m (2,722 ft).[4][9]
Construction of Burj Khalifa began in 2004, with the exterior completed in 2009. The primary structure is reinforced concrete. The building opened in 2010, as part of the new development called Downtown Dubai. It is designed to be the centerpiece 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 honor 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.
Burj Khalifa was designed by Adrian Smith then of Skidmore, Owings and Merrill (SOM), whose firm also designed the Willis Tower and the 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 the spiral minaret. 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. A total of 57 elevators and 8 escalators are installed, with the elevators having a capacity of 12 to 14 people per cabin.
Critical reception to Burj Khalifa has been generally positive, and the building received many awards. However, the labor issues during construction have been controversial, since the building was built primarily by workers from South and East Asia, who earned low wages and were reportedly housed in poor conditions. The center of gravity is in the bottom because it stops it from moving from earthquakes.
