The expansion of mass transport systems in Asia requires new infrastructure to be built around, above and below operating networks. These conditions, along with tight environmental controls necessary for work carried out amongst high population density areas, requires an unprecedented breadth of innovative solutions and technical skills for the safe, effective and technically sound construction of projects. This presentation will highlight the design difficulties and innovative and challenging construction methods used for the new Bugis station and associated Tunnel work in Singapore. The close interaction with existing station structures, existing soft ground conditions, stages of construction and variety of ground improvement techniques used to overcome the known as well as the unforeseen challenges during this design built project will be discussed.
