Built in 1975 to meet growing air traffic demand for Calgary, the main air terminal building, tunnel and roadways were built under three lump sum contracts. The building was a combination of pre-cast and cast-in-place concrete, in a unique design to permit long-term expansion. Durable finishes were used to ensure longevity of the structure; special “Texas Tan” concrete was imported and used in pre-cast members to give the airport a warm tone and appealing exterior. Future expansion was an important consideration for the designers. Design and construction allowed the building to be easily updated and expanded as demand increased.
Since the airport’s commissioning, CANA has participated in several renovations as a result of Calgary’s expansive growth.
