Ground distresses such as ground settlement/subsidence, lateral movement, cracking, etc, are usually the main concern for any excavation project. The contributory factors of ground distresses could be from various aspects and sometimes are similar in nature. This paper presents the processes of geotechnical investigation, remedial design, construction monitoring for two case histories of ground distresses occurring on a retained platform due to excavation in filled ground. Desk study, site inspection and subsurface exploration have been deployed to reveal the evidences and identify probable causes of the distresses. Back analyses utilizing finite element computer program “Plaxis” proved useful to reveal the inherent mechanisms of ground distresses. Lessons learned from the investigations are documented as useful mementos for future projects of similar nature.
