Identification and Prioritizing the Preventable Safety Hazards in Mass Housing Projects using the Integrated Multi-Criteria Decision-Making Method by Applying the Building Information Modelling (BIM) Approach

Construction operation is among the most hazardous sectors in terms of occupational accidents. On the other hand, as construction activities are scattered in different locations; therefore, monitoring their safety is a great challenge. Despite various advantages of implementing safety management in the construction projects, the lack of knowledge of designers in terms of prerequisites and not implementing the safety management system, also the lack of tools and novel technologies in the design stage of construction projects, have caused that the system remain yet to be properly evaluated. The Building Information Modelling (BIM) is one of the technologies that has gained popularity among the project managers. Among the most important applications of this approach, one could refer to its unique capabilities in maintaining the safety of project sites. The main objective in the present research, is identification and prioritizing of preventable safety hazards in the mass housing projects using the integrated multi-criteria decision-making method by applying the building information modelling (BIM) approach. For this purpose in the present research, in addition to interviewing the specialists and experts related to this study, the research works by other researchers has been used. Also, the important criteria for reducing the preventable hazards in the mass housing projects were identified. Then, using the SWARA method, the identified criteria were weighted and in continuation using the WASPAS method the criteria were prioritized based on their importance. The findings of the current research showed that the safety management system criterion with Qi=0.54657 is the most important factor in terms of reducing preventable safety hazards in mass housing projects using the BIM approach.
