At 447,000 sq. ft., the Stoney CNG Bus Storage and Transit Facility is the largest indoor compressed natural gas facility in North America. It provides a state-of-the-art bus storage, servicing, and maintenance facility for The City of Calgary and Calgary Transit. It includes indoor storage for 474 buses, six service bays, a 36-bay maintenance garage with associated offices, parts storage and warehouse, and main administrative offices and amenities. The exterior site, located on a protected wetland and designated reserve, includes 574 parking stalls and storm-water management ponds.
The Stoney CNG Bus Storage and Transit Facility was the first ever public-private-partnership (P3) project undertaken by Calgary Transit. The P3 delivery method transferred the client’s cost, schedule, and performance risk to parties that were best suited to manage potential risks. PCL and its project partners Plenary Group (Canada) Ltd., AECOM Canada Ltd., Johnson Controls, and TD Securities formed the consortium that would oversee the project — Plenary Infrastructure Calgary LP.
The consortium was responsible for delivering the full life cycle of public infrastructure project, including the design, construction, and financing. Additionally, members of the consortium will provide ongoing maintenance for the Stoney Transit Facility for 30 years. This holistic approach to construction ensured that all aspects of a high-functioning facility were considered from the outset and optimized when possible. Using the P3 model was a direct benefit to the client, and the project was delivered on time and on budget.
