Central City - Galleria Roof Surrey, British Columbia

Twenty Trusses, roughly 20 feet wide and up to 90 feet long, make up the 450-foot roof structure which spans the Galleria over both shopping and universtiy spaces below. Each truss, with its glulam chords, round timber struts and galvanized steel cables, was built adjacent to the shopping centre and hoisted into place. The roof’s supports accommodate more than 12 inches of seismic movement in any direction while allowing the glazed clerestory to illuminate the space below.
