(Newser) – An unfinished skyscraper in Dubai is now scraping the sky at 1,680 feet, surpassing Tawain's Taipei 101 as the world's tallest building. The Burj Dubai, which began construction in September 2004, will cost $1B and consist of more than 160 floors and 56 elevators when completed in 2008.

The tower's final height is a secret but it's expected to rise more than 2,295 feet. The building's architects are American and the main contractor is South Korean; most of the 4,000 laborers building the skyscraper are from India,  Al Jazeera reports, toiling in three shifts around the clock and receiving no set minimum wage.
