This study focuses on the piling works of Mass Rapid Transit (MRT) line 1 construction project along Sungai Buloh Station to Kajang Station in Malaysia, considering that piling work is one of the high risk construction activities. This study utilizes risk assessment tool using Hazard Identification, Risk Assessment & Risk Control (HIRARC) to create safe construction workplace. The hazard identification is a process of examination work area and task inherent to piling activities. The risk assessment of piling works calculated using likelihood and severity. Based on the hazard identification and risk assessment results, control measures or risk control are taken into action. The risk assessment sheets as the research instrument tool were filled by 30 construction professionals and safety practitioners i.e. safety officers, safety supervisors, site engineers and site supervisors. The results indicated that there were seven hazards that associated with piling works. One of the hazards which caused structure collapse during test pile activity was assessed as the extreme risk. Other six hazards were assessed as high risk. The total 27 risk control measures were resolved in order to eliminate and reduce hazards as well as prevent accident during piling work at the MRT construction project. © 2019, Asociatia Geographia Technica.
