Trans Mountain Expansion Project (TMEP) and Coastal Gas Link (CGL) – Pipelines through British Columbia and Alberta, Canada

During 2021 & 2022, GCS Geotechnical provided sheet pile lateral support designs for 20No. deep pipe-jacking pits for the approximately 1500km long pipeline from Alberta to British Columbia, in Canada. The designs were based on the analysis of existing geotechnical information provided and using the D-Pile program to determine the optimal depth of embedment for the cantilever sheet piles.
