The iconic twist of the Cayan Tower—which was previously known as the Infinity Tower but was renamed for developer Cayan Investment & Development—is achieved by rotating each of the hexagonal floor plates around the building’s cylindrical core by just over one degree, totaling the building’s 90-degree twist. The resulting curved skin is, in fact, flat on most surfaces, allowing for repeated, vertical glazing units, except at the corners, which had to be carefully articulated. Inside, the perimeter columns are tilted in relation to the floor plate, but maintain an identical profile, whereas the core and interior columns twist, like the overall structure, as they ascend. Mechanical, electrical, and plumbing systems are run through the central core, allowing for a straight path for utilities. This ability to maintain efficiencies across each floor plate allowed the team to create as close to a twisted extrusion as possible; “something that is very efficient, economical, and logical,” Wimer says, and “that has a very beautiful sculptural shape that makes this image on the skyline very memorable.”
