The accident cost ratio for Malaysian railway projects towards sustainable and safe construction / Nik Nur Khairunnisa Nik Mohammed Ainul Azman

The construction industry is perceived to contribute significantly to national economic growth and offers substantial opportunities for job creation. However, accident in the workplace have continually plagued the industry. Studies on the concept of accident, it contributes to costs typically comprise direct and indirect costs that commonly expressed in the form of a ratio. However, this research argues that accident in Malaysian railway projects affect to direct and indirect accident cost. Other than that, there was a limited study on the accident cost ratio that focused on railway construction projects. The accident situation and works environment in a railway construction projects are unique compared to building construction projects. Hence, further research is required to fill the gap. Therefore, the research aimed to determine the direct to indirect accident cost ratio for Malaysian railway projects. A mixed-method approach was used in this research, where both qualitative and quantitative data was utilized in the methodology phases. Semi-structured interview was carried out for first objective which is face validity involving 10 panels of expert in railway construction field. Then, structured interviews using the questionnaire was carried out for second and third objectives. A total of 70 accident cases reported at the guideway packages projects of the Mass Rapid Transit Sungai Buloh-Kajang Line (MRT SBK Line) and Light Rail Transit Line Extension Project (LRT LEP) were examined.
