ABSTRACT: This paper focuses on the approach that Pembina Pipeline Corporation and their geotechnical consultant Advisian, Worley Group adopted to manage the geotechnical risk related to a horizontal directional drilling (HDD) crossing under the Saddle River in Alberta, Canada. A focused desktop study was completed, with main reference to the well-documented Rycroft Landslide, which occurred in 1990 and is situated approximately 3 km away from the site. In addition, a geotechnical and geophysical site investigation comprising four boreholes, laboratory testing and Electrical Resistivity Tomography (ERT) was completed. The geological model and the interpretation of the extent and mechanism of the Rycroft Landslide were considered to determine the “no-drill zone” of the HDD crossing, which was successfully completed in 2019, exceeding a length of 2.2 km and reaching depths of 170 meters below ground surface.
