David Sugden Paper Presentation - Design & construction of pedestrian underpass below an existing metro tunnels & station

This webinar presents design and construction issues of two pedestrian tunnels from Thomson Line metro in Singapore which were built below two operating metro lines. Two tunnels with cross-sectional area ranging from 50m2 to 85m2 are excavated below an existing operational rail tunnel (with vertical clearance of less than 2.7m) and below an operational metro station. The tunnel excavation below the operational metro tunnel is carried out using pipe roof method and the tunnel excavation below the existing station base slab is carried out by underpinning the structure as the excavation progressed.
