EXPLORE! 4th-Jan-2010 - Dubai Made History! The Tallest Building On Earth. Burj Khalifa Inauguration.
Mohamed Ali Alabbar, chairman of Emaar Properties, the developer behind Burj Khalifa, told the BBC that the building's design had posed unprecedented technical and logistical challenges, not just because of its height, but also because Dubai was susceptible to high winds and was close to a geological fault line.
"We have been hit with lightning twice, there was a big earthquake last year that came across from Iran, and we have had all types of wind which has hit us when we were building. The results have been good and I salute the designers and professionals who helped build it," he said.
