The Stade TELUS - Université Laval stadium was part of a major regional project to expand Université Laval’s sports complex, known as the “PEPS.” Fitted out with a 100-metre-long, 60-metre-wide synthetic field, this new facility will be used for soccer, football and rugby. Abutting the existing outdoor football field, this building will serve as a functional interface between both components, which share a number of services.
The use of a glulam main frame not only complies with the client’s desire to construct a sustainable building but also satisfies numerous technical requirements. Indeed, a hybrid structure combining wood arches and straightening beams with steel struts makes for a flexible design. The architectural volume thus boasts maximum clearance over the centre of the playing area (18 m.), a 68.5-metre-long clear span between the supports and a raised roof line, thereby creating a fluid form and promoting natural ventilation.
In addition, thanks to prefabrication, the structure could be quickly erected – even in winter and despite the inclusion of 13 huge, tapering three-hinged arches. An innovative European technique involving steel dowels and self tapping screws was used in the structural connection system comprising arch load-bearing joints and metal-wood connectors, thus producing discreet, eye-pleasing connections. Thank to this structural choice, approximately 1,500 fewer tons of CO2 were emitted during construction.
All in all, the volume of wood used in this structure totalled about 1,250 m³. The cost of this hybrid structure, including supplies and installation, topped out at $4.63 M in a project totalling $25 M.
