This week is National Engineers Week. And a project currently under construction demonstrates just how far the practice and technology of engineering has come.
As of 5 February 2008, Burj Dubai has reached a height of 604.9 m (1,985 ft), with 159 completed floors.
Burj Dubai's last two milestones will be to surpass the 628.8 m (2,063 ft) height of the KVLY-TV Mast in North Dakota, United States to become the world's tallest structure and to pass the Warsaw radio mast in Gąbin, Poland (646.4 m (2,121 ft) until it collapsed in 1991) to become the world's tallest structure of any type ever built.
The projected final height of Burj Dubai is officially being kept a secret due to competition from other buildings under construction or proposed; however, figures released by a contractor on the project have suggested a height of around 818 m (2,684 ft). Based on this height, the total number of habitable floors is expected to be around 162. However, when pressed for a more precise figure, the project manager merely repeated that he was able only to guarantee that the final height would be higher than 700 m (2,297 ft), and it would be the world's tallest free-standing structure when completed.
