Burj Khalifa

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).

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.

Dubai

Dubai (/duːˈbaɪ/ doo-BY; Arabic: دبي‎ Dubayy, Gulf pronunciation: [dʊˈbɑj]) is the most populous city in the United Arab Emirates (UAE). It is located on the southeast coast of the Persian Gulf and is one of the seven emirates that make up the country. Abu Dhabi and Dubai are the only two emirates to have veto power over critical matters of national importance in the country's legislature. The city of Dubai is located on the emirate's northern coastline and heads up the Dubai-Sharjah-Ajman metropolitan area. Dubai is to host World Expo 2020.

Dubai has emerged as a global city and business hub of the Middle East. It is also a major transport hub for passengers and cargo. By the 1960s Dubai's economy was based on revenues from trade and, to a smaller extent, oil exploration concessions, but oil was not discovered until 1966. Oil revenue first started to flow in 1969. Dubai's oil revenue helped accelerate the early development of the city, but its reserves are limited and production levels are low: today, less than 5% of the emirate's revenue comes from oil. The emirate's Western-style model of business drives its economy with the main revenues now coming from tourism, aviation, real estate, and financial services. Dubai has recently attracted world attention through many innovative large construction projects and sports events. The city has become iconic for its skyscrapers and high-rise buildings, in particular the world's tallest building, the Burj Khalifa. Dubai has been criticised for human rights violations concerning the city's largely South Asian workforce. Dubai's property market experienced a major deterioration in 2008–09 following the financial crisis of 2007–08, but the emirate's economy has made a return to growth, with a projected 2015 budget surplus.

The Dubai Fountain

The Dubai Fountain is the world's largest choreographed fountain system set on the 30-acre manmade Burj Khalifa Lake, at the center of the Downtown Dubai development in Dubai, United Arab Emirates. It was designed by WET Design, the California-based company responsible for the fountains at the Bellagio Hotel Lake in Las Vegas. Illuminated by 6,600 lights and 25 colored projectors, it is 275 m (902 ft) long and shoots water up to 500 ft (152.4 m) into the air accompanied by a range of classical to contemporary Arabic and world music. It was built at a cost of AED 800 million (USD $218 million).

The name of the fountain was chosen after a contest organized by the developer Emaar Properties, the result of which was announced on 26 October 2008. Testing of the fountain began in February 2009, and the fountain was officially inaugurated on 8 May 2009 along with the official opening ceremony of The Dubai Mall. On 2 January 2010 the length of Dubai fountains was increased to 275 m (902.2 ft).
