World's tallest twisting tower added to Dubai skyline [slideshow]

The SOM-designed Cayan (formerly Infinity) Tower—the world’s tallest twisting tower—has opened in Dubai, United Arab Emirates. The 75-story residential building features a dramatically rising helix shape for a distinctive addition to the city’s skyline.

The reinforced concrete structure consists of a hexagonal floor plate rotated around a circular core, giving apartments on the lower portion of the tower different views from those on upper floors. MEP systems are situated in the core, allowing straight vertical paths for infrastructure; locations of perimeter columns vary from floor to floor.

Saudi Arabia-based Cayan Investment & Development was the real estate developer. Also on the Building Team: local design consultant Khatib & Alami and primary contractor Arabtec Construction.
