Cayan Tower, known asInfinity Tower before it was inaugurated, is a 306-metre-tall (1,004 ft), 75-storyskyscraper in Dubai,United Arab Emirates. The tower is designed bySkidmore, Owings and Merrill SOM architectural group for Cayan Real Estate Investment and Development. Upon its opening on 10 June 2013, the tower became the world's tallest high-rise building with a twist of 90 degrees. This record has since been surpassed by theShanghai Tower, which opened in February 2015.
The twisting design of Cayan Tower was achieved by rotating each floor 1.2 degrees around a cylindrical elevator and service core.[4] Prior to its name change to Cayan, the tower carried various names to describe its original shape. The unique design was supported by a dynamic analysis that studied the potential performance of the tower under wind, seismic, and other dynamic loads.[5] Cayan Tower's apartments are designed with reconstituted wooden floors, Chinese synthetic marble counter tops, and kitchen fixtures.[relevant?] The tower also includes a five-story parking garage behind it.[6]The rooms of the tower are designed in such a way that it would not be affected by direct sunlight due totitanium-coloured metal panels on cast-in-place concrete columns aided with repetitive staggered screen panels to stop penetrating sunlight from disturbing the residents of the unit.
The tower's construction was on hold for a year and a half after the foundation site of the tower was flooded when the wall that held back the Dubai Marina was breached on 7 February 2007.[7][8] Witnesses described a loud cracking sound, followed by an inflow of sand and water. The project resumed construction in July 2008.
The Cayan Tower was inaugurated with fireworks accompanied with laser light display on the tower on 10 June 2013 and become the world's tallest twisted tower, surpassingTurning Torso.[9][10] The tower was renamed Cayan Tower, with the developer saying,[relevant?][11]
there [ is ] more than one tower with the name Infinity and we wanted something different [ . . . ] We are very attached with this unique project and it was a very conscious decision we took. We know there won’t be any Cayan Tower in the world and this will be the only one.
