Chinook Arc

Calgary, Alberta

Chinook Arc

Believed to be the largest acrylic sculpture in the world, Chinook Arc is an interactive, illuminated sculpture intended to bring people together. The complex engineering behind this 28’ x 15’ structure was a year in the making and broke new ground. The skin of the sculpture doesn’t actually touch the skeleton; rather, it floats on a space frame sub-skeleton. Despite how delicate this sounds, the skin was designed with resilient materials like galvanized steel, stainless steel, acrylic and silicon to withstand regular human interaction and Calgary’s climate. It was installed in just a few weeks.
