Holy Trinity Catholic High School | École Secondaire Sainte-Trinité

Fort McMurray, Alberta

Holy Trinity Catholic High School (HTCHS) is located on a shared site with a Junior High School in the Timberlea subdivision. During the design process, key factors such as materials, detailing, siting, and vehicle circulation were explored, starting with the evaluation of a comparable school. Spaces that functioned well were incorporated; however, since Holy Trinity was a Senior High School, some specialized functions were added that required the development of new, detailed room data sheets. 

Accommodating 1,100 Senior High School students and the required parking would absorb much of the land. A two-storey design was developed to optimize space while allowing for future expansion. The inclusion of a "black box theatre" – a valuable amenity for the school and the community – enhanced the school’s offerings, adaptable for professional productions and various events. In addition, numerous features helped reduce capital, operating, and energy costs, while ensuring long-term durability.

The remoteness of Fort McMurray and a tight labour market were important considerations in the design process. Pre-cast concrete panels reduced on-site labour and “season-proofed” construction, mitigating winter conditions. Daylighting was optimized for energy use and psychological wellness. An innovative ACI-designed, panelized system with lighting allowed the school to change colours – evoking the Aurora Borealis. Panels and lighting were integrated into the building exterior to offset finish costs.

ACI successfully met the scope expectations, while supporting the cost-sharing agreements among four stakeholders: the Fort McMurray Catholic Board of Education, the theatre’s funding sponsor Suncor, Alberta Education, and Alberta Infrastructure.
