Determining Optimal Risk Assessment Model in Construction Projects (Case study: steel plant construction project)

Introduction: Identifying occupational hazards and managing occupational safety and health risks is the most important mission and responsibility of the health and safety management system in organizations and adopting coded plans to achieve this is the key to continuously improving this system and promoting it. Method: This descriptive-analytic research has been written to determine the optimal risk assessment methodology in development projects. In this research, using previous research studies and collecting expert opinions, the most important criteria for selecting a specific risk assessment methodology, and then using one of the three most-used techniques, is an important activity in the steel making industry and risk assessment. Then, the decision matrix is based on the strengths and weaknesses of the models. Results: The prioritization of these three methods is done using the hierarchical analysis decision method. In this paper, five key factors, the degree of application in identifying hazards, usability in different stages of risk assessment, reliability, ease of use, and training needs and costs, are identified as the most important criteria for choosing a risk assessment technique and the FMEA method as The Conclusion: Risk Assessment Method is the best. FMEA's methodology has been introduced with regard to its capabilities as an optimal risk assessment method for contruction projects.
