Abstract:
Over 12,000 precast architectural and structural components were used in constructing the new International Airport complex in Calgary, Alberta, Canada. Founded on 900 pressure-injected piles, the terminal has a post-tensioned prestressed column system. Elements of the elevated roadway include 5 ft (1.5 m) square post-tensioned piers and 41 in. (1041.1 mm) deep x 66 ft (20 m) long precast single T-beams, post-tensioned to continuous edge girders. In the parking garage, precast single T-beams spanning 60 ft (18.3 m) are post-tensioned to precast columns and stair cores. The 5 in. (127 mm) thick cast-in-place deck is also post-tensioned.
