Stoney Compressed Natural Gas Bus Storage and Maintenance Facility

To support operations of the new fleet of buses, the City of Calgary pursued a P3 agreement for the design, construction, finance, and maintenance of a greenfield transit facility. This is the first large-scale public-private-partnership (P3) project undertaken by the City.

Project Scale

550,000 sq. ft.

Planning for the future.

The new facility includes 36 maintenance bays, two steam bays, and associated administrative support space. The new LEED Gold facility is approximately 550,000 sq. ft., and home to more than 424 buses. Our team acted as the bridging team lead for the City, responsible for procuring, organizing, and directing a team of 10 specialist discipline sub-consultants. We took responsibility half-way into the P3 proponent RFP phase. We were responsible for preparing the Owner’s Statement of Requirements, administration of the procurement process, RFI responses, reviewing and evaluating proponent’s submissions, and making recommendations. We monitored design, construction, and close-out, and attended all project meetings, advised the City on issues, and reviewed and made recommendations with respect to all change orders.
