Geological Challenges encountered in Deep Singapore Underground during the Constructions of Transmission Cable Tunnel Projects

by Bryan Kyaw Thet Oo, SP Group Ltd

Synopsis

The multibillion-dollar Underground Transmission Cable Tunnels Project, also one of the world’s deepest electricity supply project, is built at 60m average depth to replace Singapore’s aging power cables for operational reliability and to meet future energy needs. This project brings numerous and intricate geological, geotechnical and construction challenges during deep shaft excavation, adit mining and bored tunnelling works, most of which are never experienced before in the past Singapore’s underground history.  By and large, this presentation covers the rare and interesting geological findings and challenges which would create a good platform for technical discussions among professionals.
