Houle Chevrier Engineering Ltd. (HCEL) was retained by McDonald Brothers Construction Inc. to provide geotechnical services for a design-build contract for the Canadian International Hockey Academy in Clarence-Rockland.
The project is located in an area underlain by deposits of silty clay of marine origin having a thickness of more than 30 metres. To avoid unnecessary design and construction cost, HCEL carried out downhole shear wave velocity testing to accurately determine the Seismic Site Class in accordance with building code requirements. The use of spread footing foundations was achieved in part through the use of light weight Expanded Polystyrene (EPS) fill blocks on the exterior of the foundations.
Project components included:
- Downhole shear wave velocity testing to accurately determine the Seismic Site Class
- Design of spread footing foundation alternative
- Design of light weight EPS fill on the exterior of the building to keep settlements within tolerable limits
- Geotechnical inspection and testing during construction
