About 

Synopsis:

Two case studies on deep excavation and viaduct foundation constructed in Kuala Lumpur Limestone shall be presented including the various challenges encountered and the solutions adopted. The first case study on deep excavation will present the use of single large diameter bored piles in Limestone Formation with the appropriate cavity treatment for the building foundation, basement retention system using secant bored pile (SBP) and contiguous bored pile (CBP) with internal strutting and partial top-down / bottom-up excavation method and also the instrumentation monitoring carried out on site. The second case study on viaduct foundation will present the short single pile foundation requirement, construction constraints and the use of light weight backfill material in the form of expanded polystyrene (EPS) blocks to construct the road embankment underlain by the existing SMART and MRT tunnels.
