The Integrated Methodology of Health, Safety, and Environmental (HSE) Risk Assessment based on the Project Management Body of Knowledge (PMBOK)

One of the major challenges in construction projects is the mismatch of risk concepts in HSE and project management as a result of negligence in HSE matters on the part of project managers. The current study was aimed to clarify the risk management principle as an important domain of PMBOK and to present an integrated HSE risk assessment tool according to PMBOK. This cross-sectional study was done to analyze 21 risks of the four types of HSE risks using PMBOK in one of the biggest construction projects in 2019. The risk matrix including likelihood and severity was the basis of this integrated risk assessment model. The severity of consequences includes four types of impacts (impacts on project’s costs, timing, quality and human force), and also the weighting coefficient of each dimension was applied based on the importance of each consequence. The results showed that among 21 identified sources of risk, nine sources were at a high level (3rd level) and only one source was at a low level (1st level). Moreover, it has been founded that among the four types of HSE risks including work breakdown structure, project costs, quality, and emergency situations in construction projects are at the highest level. In cases that there was no money allocated for hiring supervisor, expert, and HSE officer considering different project phases has been evaluated as the highest source of danger. The current study provided an appropriate alternative for commonly used risk assessment methods in construction projects because it made a whole change in projects managers’ and HSE members’ points of view and presented a new attitude toward risk identification, consequence analysis, and the usage of PMBOK project management standard in the risk management process in construction projects.
