SYNOPSIS

To improve and enhance inter-town connectivity within urban areas and reduce travel time, Mass Rapid Transit (MRT) system emerges as an optimal environmentally-friendly green solution. Presently, most of the MRT systems are built underground, a strategic choice aimed at conserving land resources, preventing traffic and utility disruptions, and minimizing adverse effects on the local community. Consequently, Tunnel Boring Machines (TBMs) are employed to excavate tunnels and establishing the underground network.

Safety is placed at the forefront of planning and execution processes when it comes to Tunnel Boring Machine (TBM) operations beneath the ground with foremost commitment by specialist builder. This talk will present the challenges that encountered in LRT3 tunnelling, along with the strategies employed to mitigate these risks through thorough geological analysis and precise machine selection. Additionally, valuable insights on optimizing site layout and engineering solutions to enhance the efficiency of tunnel construction while successfully overcoming various challenges will be shared and discussed.
