Slip failure at NUS

A slip failure occurred on January 11, 2006 in a 19 m high existing fill slope built in early 1980’s during the construction of NUS’ Business School Block 2 (Biz 2). The failure occurred after a wet weather period lasting since December 2005 and a prolonged rainstorm on January 10, 2006. The major slip extended from the mid berm between RL 122 m and RL 123 m to the toe of slope causing soil heave and damage to the open drain along Car Park 11. Minor slip was observed within the upper slope above ~RL 123 m, resulting into a steep soil face right beside the Biz 2 Building.

Scope of work

• Case Study and Report on Causes of Slope Failure
