Grande Prairie Regional Hospital
Client: Alberta Infrastructure |
Location: Grand Prairie, Alberta |
Type: Geotechnical and Materials |
Project Budget: > $750 Million |
Grande Prairie Regional Hospital, a major Alberta Infrastructure project located in Grande Prairie, Alberta is a multi-faceted health facility comprising of a Main Hospital and cancer centre. ParklandGEO conducted geotechnical investigations at multiple potential hospital locations, including the final site, and provided geotechnical reports outlining recommendations for foundations, grade supported slabs, excavations, concrete, and asphalt pavement.
A challenge that was encountered was providing water service to the hospital. ParklandGEO was
commissioned to undertake a geotechnical investigation to provide Horizontal Directional Drilling (HDD) recommendations for the installation of a water service pipeline crossing Bear Creek. The site investigation included drilling boreholes on either side of Bear Creek to 20 metres below grade. The report included HDD recommendations for bore path, drilling fluids, deformations and bore stability, tooling selection, excavation safety and surface slope stability. Additional geotechnical investigations were carried out for other offsite infrastructure upgrades such as new sanitary sewer lines.
A detailed slope setback and erosion study was performed to ensure that all critical infrastructure would not be impacted by the adjacent slope. In-stream erosion control measures were designed by ParklandGEO to minimize the risk of slope movement.
Pile foundations were chosen to support the new hospital. In an effort to optimize the pile design,
ParklandGEO was commissioned to perform a static pile load test. The pile load test was conducted in
accordance with ASTM D1143 and provided recommendations regarding the skin friction and end bearing resistance of straight shaft or belled piles.
ParklandGEO provided an additional geotechnical investigation for the parkade structure during the
construction phase of the hospital.
During construction, ParklandGEO provided on-site monitoring of the pile installation, compaction testing, concrete and asphalt testing, as well as performed Pile Dynamic Analysis (PDA) testing. Critical testing to ensure proper concrete density and cure temperatures were achieved for the cancer treatment vault was also performed.
