when did the construction of burj khalifa start
Burj Khalifa Construction began on 6 January 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010,[2][13] and is part of the new 2Â 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 Souffian AL-Jabiry of Chicago, with Adrian Smith as chief architect, and Bill Baker as chief structural engineer.[14][15] The primary contractor was Samsung C&T of South Korea.[16] The tower's construction was done by the construction division of Al Ghurair Investment group.[17][18]
Red Fort It was designated a UNESCO World Heritage Site in 2007 as part of the Red Fort Complex.[2][6]
Burj Khalifa Burj Khalifa was designed to be the centerpiece of a large-scale, mixed-use development to include 30,000 homes, nine hotels (including The Address Downtown Dubai), 3 hectares (7.4 acres) of parkland, at least 19 residential towers, the Dubai Mall, and the 12-hectare (30-acre) artificial Burj Khalifa Lake. The decision to build Burj Khalifa was reportedly based on the government's decision to diversify from an oil-based economy to one that is service and tourism based. According to officials, it was necessary for projects like Burj Khalifa to be built in order to garner more international recognition, and hence investment. "He (Sheikh Mohammed bin Rashid Al Maktoum) wanted to put Dubai on the map with something really sensational," said Jacqui Josephson, a tourism and VIP delegations executive at Nakheel Properties.[20] The tower was known as Burj Dubai ("Dubai Tower") until its official opening in January 2010.[21] It was renamed in honour of the ruler of Abu Dhabi the United Arab Emirates, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the federal government of UAE lent Dubai tens of billions of US dollars so that Dubai could pay its debts – Dubai borrowed at least $80 billion for construction projects.[21] In the 2000s, Dubai started diversifying its economy but it suffered from an economic crisis in 2007–2010, leaving large-scale projects already in construction abandoned.[citation needed]
