Abstract

The construction industry is known as one of the most dangerous industries in the, work-related mortality,
injury rates and workers compensation payment. Industrial accidents are due to inefficiency of
conventional methods of risk assessment and performing activities, regardless of safety standards, that it
will affect extremley on health and safety staffs. Thus, identifying and assessment risks are an essential
step in this industry. The safety analysis is an effective act for the identification, assessment and control
of risks in construction industry. This paper uses systematic and integrated AHP-DEA methodology for
safety risk assessment. In the case study of Iran’s common construction projects, 20 danger potential
activities with high potential of hazards, 10 accident caused by these activities and 12 factors for identification
of causes of accidents are enacted. They were evaluated using judgment of safety experts and
projects supervisors by questionnaire. Finally, excavation activities and work in elevations were recognized
the most risky activity in terms of safety, that strategies were presented to improve and prevent
accidents caused by these activities.
