The Dynamic Tower (also known as Dynamic Architecture Building or the Da Vinci Tower) is a proposed 420-metre (1,378 ft), 80-floor tower in Dubai, United Arab Emirates.
The tower is expected to be architecturally innovative for several reasons. Uniquely, each floor will be able to rotate independently. This will result in a constantly changing shape of the tower. Each floor will rotate a maximum of 6 metres (20 ft) per minute, or one full rotation in 90 minutes. It will also be the world's first prefabricated skyscraper. 90% of the tower will be built in a factory and shipped to the construction site. This will allow the entire building to be built in only 18 months. The only part of the tower that will be built at the construction site will be the core. Part of this prefrabrication will be the decrease in cost and number of workers. The total cost will be 23% less than a normal skyscraper of the same size, while only 90 people will work on the construction site. The majority of the workers will be in factories, where it will be much safer. The entire tower will be powered from turbines and solar panels. Enough surplus electricity should be produced to power five other similar sized buildings in the vicinity. The turbines will be located between each of the rotating floors. They could generate up to 1,200,000 kilowatt-hours of energy from the movement of the floors. The solar panels will be located on the roof. Construction of the Dynamic Tower, if built, is expected to be completed in 2010.
