Towards a Better Reliability of Risk Assessment: Qualitative & Quantitative Risk Evaluation Model (Q2REM) for Different Trades of Construction Works in Hong Kong

Description

Since the safety professionals are the key decision makers dealing with project safety and risk assessment in the construction industry, their perceptions of safety risk would directly affect the reliability of risk assessment. In this study, the qualitative analysis on the safety professionals’ beliefs of risk assessment and their perceptions towards risk assessment will be explored. Further based on the findings and the historical accident data from sample construction projects, a risk evaluation model prioritizing the risk levels of different trades of works and which cause different types of site accident due to various accident causes will be developed quantitatively. With the suggested systematic accident recording techniques, this model can be implemented in the construction industry at both project level and organizational level. It can also assist safety professionals to pinpoint the potential risks on site for the construction workers under respective trades of works through safety trainings and education.
