Two sites along a Provincial highway in southern British Columbia required excavation at the roadway’s edge to expose a gas pipeline 5 meters below the roadway elevation. Due to other utility conflicts, traditional soil nail shoring was not practical, and the time and budget constraints precluded the use of traditional piling or sheeting methods.
GeoStabilization International®’s engineers designed a reticulated micropile shoring system that could be installed rapidly at minimal cost. GeoStabilization’s crews shored both sites in less than 12 days, which kept the project on-schedule and on-budget.
GeoStabilization was tasked with providing an alternate design/build strategy that required a rockfall protection barrier system at the base of the steep slope, the construction of a 30,750 ft2 soil nail wall, and installation of 4,200 ft2 of Geobrugg TECCO mesh.
