The expansion and renovation of the McMaster University David Braley Athletic Centre and Ivor Wynne Centre are expected to enhance the academic and student life of McMaster University by adding 80,000 sq. ft. of fitness and student activity space with an additional 20,000 sq. ft. of renovated fitness space.
As part of the David Braley Athletic Centre and Ivor Wynne Centre building additions, Crozier provided civil site services engineering for the expansion, which includes stormwater management and grading of the new exterior amenity space. The stormwater management component targets LEED Silver certification for this project.
Unique to this project is that the building expansion was split between two drainage areas, each with a unique outlet criteria. The storm drainage system was designed to match the post development discharge to pre-existing conditions for each outlet. Stormwater management control is achieved primarily using two subsurface storage systems complete with open bottoms to provide quantity control and promote infiltration. The use of low-profile Triton subsurface storage systems reduced earth moving costs while providing a total of 114cu.m of underground storage to meet City and LEED SWM criteria.
