The Bus Garage was the start of a much larger project which would eventually consolidate the entire Prairie South School Division offices and maintenance buildings in Moose Jaw. This first phase of construction was to provide a new maintenance shop, wash bay and site parking / development for the Division's school bus fleet, as well as supporting staff offices and parts storage for the buses. The wash bay includes an interior and exterior location. The maintenance bays provide a spot for the regular and scheduled repairs required to keep the buses running smoothly.

As the first phase in a multi-phase project, the site planning was executed to allow for future development of an additional maintenance shop and building to house all of the Division's department offices.
