Thirty Feet from 1 mile high. More than 5 times as high as the Eiffel Tower, and better than twice the size of the world's tallest building under construction, Dubai Tower. That's the size of the $10 Billion dollar, 5250 foot tower is planned in it's own "mini-city" near Jeddah, Saudi Arabia by Saudi Prince al-Walid bin Talal (know most in the States for his massive Citigroup investment, amongst others). The tower has numerous engineering challenges ahead. The building will be stabilized by 2 towers on either side which both will stand close to 100 stories each. The tower will also be subject to extreme temperature deviations. All I can say is....Wow!
