Nicoll Highway Collapse, Singapore

On 20 April 2004, a 30m deep excavation for a cut & cover tunnel, adjacent to Nicoll Highway in Singapore collapsed killing four people. The excavation was within a diaphragm wall supported by steel struts and jet grout slabs. Richard Davies led the team of experts in the subsequent Inquiry and will discuss the main factors involved in the collapse. It is hoped that other experts in the Inquiry will be present to contribute.
