​The Burj khalifa was consturted at Jan 6 2004 and finshed at Oct 1 2009. It was opened at Jan 4 2010.

​The construction name was EMARR propertes.

​

​At a certain point in the architectural and engineering process, the original Emaar developers experienced financial problems, and required more money and economic funding. Sheikh Khalifa, the ruler of the United Arab Emirates, granted monetary aid and funding, hence the changing of the name to "Burj Khalifa". The concept of profitability derived from building high density developments and malls around the landmark has proven successful. Its surrounding malls, hotels and condominiums in Down

town Dubai have generated the most revenue from the project as a whole, while the Burj Khalifa itself made little or no profit.^[8][9]

Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, there were numerous complaints concerning migrant workers from South Asia who were the primary building labour force. These centered on low wages and the practice of confiscating passports until duties were complete.^[10] Frequent suicides committed by expatriate employees who worked at the structure were reported in 2011.^[11]
