Specific recognition was given to consultant groups CH2M and Associated Engineering for their involvement and leadership in these two projects. This year’s awards committee evaluated a total of 64 project submissions from across Canada.
The Airport Trail tunnel is a critical piece of infrastructure that connects people, goods, and services locally, regionally, and globally, and serves as a vital east-west corridor for Calgary that benefits all Calgarians. The six-lane, 620 metre-long cast-in-place concrete structure is located beneath the new runway, designed to withstand aircraft landings, and boasts world-leading fire and ventilation systems.

Duane Delaney, The City’s Manager of Major Roads Projects in Transportation Infrastructure, said this award is a direct reflection of the outstanding job done by the project managers and crews in working together to complete these complex projects and in meeting the many tight deadlines.
- Completion of tunnel sections at set times so that the runway and taxiways above could be built within their tight construction schedule
- An innovative formwork system mounted on rails was used to meet the fast-track schedule
- To suit the Calgary climate, a custom concrete mix was developed that could be placed quickly and not affected by the freeze-thaw cycle
- An advanced model was developed to manage 8.1 million cubic metres of earthworks and to maximize the use of on-site materials.
