A second crossing Sg. Sarawak linking Petra Jaya and the city of Kuching, Malaysia was to be constructed to case the traffic flow on the Satok Bridge crossing located at the upper reaches of the river. A 12m high hydraulic sand-fill embankment that formed part of the approaching section to the large span bridge structure was to be built. During construction, embankment tor failure occurred and had to be suspended . Detailed transient seepage and slop stability analyses have been carried out to investigate the causes of the toe failure. Based on the detailed analyses, an improved embankment design was implemented. An instrumentation program that included water standpipes was also implemented to assist in monitoring the stability of the embankment to prevent further incidents
