The Nicoll Highway Collapse in Singapore – A Technical Perspective (Christchurch)
On 20 April 2004 at around 3:30 pm, a construction disaster struck Singapore. A section of the 20m wide cut-and-cover tunnel that was underconstruction collapsed. The excavation was about 30 m deep at the time of collapse. The tragedy left 4 workers killed and 3 injured. It rendered the highway impassable for many months and a long delay in the construction of the new rapid transit line. This talk covers the events leading up to failure, the potential causes of failure and the lessons learnt with emphasis on the design, construction, monitoring and execution of the observational method.
