On July 21, construction reached 1,680 feet on the 141st floor of the Burj Dubai tower in Dubai, United Arab Emirates, making it the largest building in the world. The skyscraper is now 13 feet above the former record holder, Tapei 101 in Taiwan, which is 1,667 feet above the ground.
Burj Dubai is the tallest building now, and according to the official site, it’s nowhere near finished. The final height and number of stories are a secret.
When finished, the building will be comprised of 330,000 cubic meters of concrete, 39,000 metric tons of steel rebar, and 142,000 square meters of glass–which will take 22 million man hours to complete.
Otis Elevator is installing 66 elevators and escalators, including two to the top observation deck. They will be the longest elevators in the world and travel at more than 20 miles per hour.
Here’s an artist’s impression of how the skyscraper will loom over the city of Dubai when completely finished, which is expected in June 2008.
