Burj Khalifa (Arabic: برج خليفة, "Khalifa tower"), known as Burj Dubai prior to its inauguration, is a skyscraper in Dubai, United Arab Emirates, and is the tallest man-made structure in the world, at 829.8 m (2,722 ft).
Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010, and is part of the new 2 km2 (490-acre) development called Downtown Dubai at the 'First Interchange' along Sheikh Zayed Road, near Dubai's main business district. The tower's architecture and engineering were performed by Skidmore, Owings and Merrill of Chicago, with Adrian Smith as chief architect, and Bill Baker as chief structural engineer.The primary contractor was Samsung C&T of South Korea.
In March 2009, Mohamed Ali Alabbar, chairman of the project's developer, Emaar Properties, said office space pricing at Burj Khalifa reached US$4,000 per sq ft (over US$43,000 per m²) and the Armani Residences, also in Burj Khalifa, sold for US$3,500 per sq ft (over US$37,500 per m²). He estimated the total cost for the project to be about US$1.5 billion.
The project's completion coincided with the global financial crisis of 2007–2012, and with vast overbuilding in the country; this led to high vacancies and foreclosures. With Dubai mired in debt from its huge ambitions, the government was forced to seek multibillion dollar bailouts from its oil-rich neighbor Abu Dhabi. Subsequently, in a surprise move at its opening ceremony, the tower was renamed Burj Khalifa, said to honour the UAE President Khalifa bin Zayed Al Nahyan for his crucial support.
Because of the slumping demand in Dubai's property market, the rents in the Burj Khalifa plummeted 40% some ten months after its opening. Out of 900 apartments in the tower, 825 were still empty at that time. However, over the next two and a half years, overseas investors steadily began to purchase the available apartments and office space in Burj Khalifa. By October 2012, Emaar reported that around 80% of the apartments were occupied.

The beachfront area where Burj Al Arab and Jumeirah Beach Hotel are located was previously called Chicago Beach. The hotel is located on an island of reclaimed land 280 meters offshore of the beach of the former Chicago Beach Hotel. The locale's name had its origins in the Chicago Bridge & Iron Company which at one time welded giant floating oil storage tankers on the site.
The old name persisted after old Hotel was demolished in 1997. Dubai Chicago Beach Hotel remained as the Public Project Name for the construction phase of Burj Al Arab Hotel until Sheikh Mohammed bin Rashid Al Maktoum announced the new name.
Design and construction
Design and Construction
Burj Al Arab was designed by architect Tom Wright of Atkins. The design and construction were managed by Canadian engineer Rick Gregory also of WS Atkins. Construction of the Island began in 1994. It was built to resemble the sail of a dhow, a type of Arabian vessel. Two "wings" spread in a V to form a vast "mast", while the space between them is enclosed in a massive atrium. The architect Tom Wright said "The client wanted a building that would become an iconic or symbolic statement for Dubai; this is very similar to Sydney with its Opera House, London with Big Ben, or Paris with the Eiffel Tower. It needed to be a building that would become synonymous with the name of the country."
The architect and engineering consultant for the project was Atkins. Fletcher Construction from New Zealand was the lead joint venture partner in the initial stages of pre-construction and construction. The hotel was built by South African construction contractor Murray & Roberts and Al Habtoor Engineering.The building opened in December 1999.There was a considerable controversy regarding the claim that the structure looks like a huge Christian cross.
Features
Several features of the hotel required complex engineering feats to achieve. The hotel rests on an artificial island constructed 280 m (920 ft) offshore. To secure a foundation, the builders drove 230 forty-meter (130 ft) long concrete piles into the sand.
Engineers created a ground/surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, while it took fewer than three years to construct the building itself. The building contains over 70,000 m3 (92,000 cu yd) of concrete and 9,000 tons of steel.Inside the building, the atrium is 180 m (590 ft) tall.Burj Al Arab is the world's fourth tallest hotel (not including buildings with mixed use). The structure of the Rose Rayhaan, also in Dubai, is 11 m (36 ft) taller than Burj Al Arab.
Rooms and suites
The hotel is managed by the Jumeirah Group. Despite its size, Burj Al Arab holds only 28 double-story floors which accommodate 202 bedroom suites. The smallest suite occupies an area of 169 m2 (1,820 sq ft), the largest covers 780 m2 (8,400 sq ft).
Suites feature design details that juxtapose east and west. White columns show great influence.[clarification needed] Bathrooms are accented by mosaic tile patterns.[citation needed]
The Royal Suite, billed at US$18,776 per night, is listed at number 12 on World's 15 most expensive hotel suites compiled by CNN Go in 2012
The Burj Al Arab is very popular with the Chinese market, which made up 25 per cent of all bookings at the hotel in 2011 and 2012.
Restaurants
Al Muntaha (Arabic for "Highest" or "Ultimate"), is located 200 m (660 ft) above the Persian Gulf, offering a view of Dubai. It is supported by a full cantilever that extends 27 m (89 ft) from either side of the mast, and is accessed to a panoramic elevator.
Worlds Biggest Fountain Series

The Dubai Fountain is the worlds 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).
