In the summer and fall of 2008, ParklandGEO was commissioned to be the geotechnical consultant for the replacement of a footbridge within Pierre Grey Provincial Park, near Grande Cache, AB. The scope of work for this project included drilling 2 boreholes, one on either end of the existing wooden bridge to assess the subsurface conditions at the site as well as performing select soil testing at ParklandGEO’s Sherwood Park Laboratory. Due to the lack of access to the island, a remote drill had to be used to drill the borehole on the far side of the bridge. The information from the borehole logs was used to give recommendations for foundation design, slope stability and construction practices.
The results of the geotechnical investigation revealed subsurface conditions that consisted of sily sand and soft sandy clays. As expected, the water table was high at the site, which would limit the use of certain types of foundation systems. Due to the nature of the site, the bridge was replaced by a single span metal bridge anchored on both shores.
The ParklandGEO personnel responsible for this project include Mike McCormick as senior engineer and Jamie Paul as project manager and field supervisor.
