A day after Dubai announced it now has the world's tallest building, the architect behind the construction – Chicago's Adrian Smith – says there is still more to come.
Smith told Chicago's Sun Times the Burj Dubai still has a long way to go before it reaches its predicted final height – of 1680ft and 140 stories (the building currently stands at 1667ft).
The final height of the building, which to date has taken just 1279 days to build, is still unknown, despite debates raging between analysts and the media.
Smith designed the building while a partner at Skidmore, Owings & Merrill. It has already hit the 'world's tallest' list, exceeding the heights of the Petronas Towers in Malaysia and Taipei 101 in China, designed by CY Lee.
"I think it's an extraordinary event that Burj Dubai has now surpassed Taipei 101, even though the building is still a considerable way from being topped out," Smith told the paper.
"The exterior walls have been slow in coming, but overall the building is doing very well, both financially and in terms of the construction schedule."
Developer Emaar Properties says the building has been especially designed with reinforced concrete and 62,200t of reinforcing steel to manage the effect of wind and seismic movements with its 80,000m2 foundation slab and 50m deep waterproofed piling and cathodic protection.
