Safety Costs evaluation in Construction Industry Using Risk Assessment Approach

Establishing safety at work is one of the essential and necessary conditions for starting, performing, ending and exploiting work. Due to the importance of this issue, in the present study, the evaluation and management of safety risks in the construction industry in the direction of human health using multi-criteria decision-making techniques have been done. In the framework of the proposed method, safety risks in construction projects were first extracted according to the study of previous researches and opinion polls of experts and experts, who are divided into four general categories including machinery, fire, work at height and unexpected accidents. Then the questionnaire is designed based on these risks and is distributed among the statistical sample. After reviewing the validity and reliability of the questionnaire, the mentioned factors are ranked based on the costs of providing workforce for safety and health of workforce using the fuzzy hierarchical analysis method. The results of fuzzy hierarchical analysis method show that the factor of people getting stuck between machines is the most important that should be considered in all stages. The next most important factor is the accident with the machines. The third factor is the throwing of materials from machines. Thus, due to financial constraints in this regard, in order to manage safety in construction projects, it is necessary frst to consider the factors that have priority. In the end, based on the obtained rankings, suggestions are provided in order to ensure the health of human resources.
