Abstract: The Changi East Reclamation projects in Singapore were implemented in five phases starting from 1991 and completed in 2005. Due to the excessive magnitude of settlement likely to occur over a long period of duration caused by the consolidation process, an extensively large area was required to be improved using ground improvement techniques to accelerate the consolidation process. The planning and implementation of site investigation works for land reclamation projects is discussed in this paper. An accurate and extensive geotechnical characterisation of underlying soft compressible marine clay was undertaken as part of this project. The geotechnical characterisation was undertaken using site investigation, specialised laboratory testing and specialised in situ testing. Correlations were obtained using empirical methods, which will be useful for future use such as correlations between classification parameters as well as specialised in situ test parameters and strength and compressibility parameters of Singapore marine clay at Changi, Singapore. This paper presents how the research-oriented ground investigation projects were implemented for this mega land reclamation project in the Republic of Singapore.
