In the fall of 2008, ParklandGEO was commissioned as the geotechnical consultant for the Investigation of slope failure near a truss bridge in Saddle Hills County, AB. The scope of work for this project included drilling 9 boreholes to assess the subsurface conditions at the site as well as performing select soil testing. Slope inclinometers were installed in four of the boreholes and the slope was monitored for movement by ParklandGEO personnel. The information from the borehole logs and slope indicators was used to give recommendations for foundation design, slope stability and construction practices.
The results of the geotechnical investigation revealed that the slope was sliding towards the bridge, which “sandwiched” the bridge between the two banks and caused foundation problems. The water table was relatively high at the site, which contributed to the slope instability. Several different remediation procedures were recommended by ParklandGEO including dewatering, installation of a shear key, toe loading, and construction of a floating foundation that would allow small slope movements.
The ParklandGEO personnel responsible for this project include Mike McCormick as senior engineer and Jamie Paul as project manager.
