Based on the history of the occurrence of abundant HSE problems in the construction phase of dams and hydropower plants (as a source of renewable energy), identification and assessment of HSE risks in these projects is of high importance. So, the aim of this study is determined to provide a model for the evaluating HSE risks in the construction phase of Bakhtiari dam and hydropower plant. First, risks were identified using the literature of the issue and interviews with experts. Then, the identified risks were analyzed using FMEA method combined with fuzzy logic. Since the severity parameter is more ambiguous for the experts than the two other parameters, it was calculated by considering the following four sub-criteria of cost, time, quality and individual. The weights of these criteria were achieved using fuzzy AHP method. Based on the results, the highest risk priority number of environmental risks is related to aquatic habitat quality loss and the highest risk priority number of safety and health risks is related to decrease in the individual's concentration and performance. Finally, among total risks, aquatic habitat quality loss, soil erosion escalation, and decrease in the individual's concentration and performance were identified as the most important risks respectively.

This study attempts to determine and assess the Risks due Construction of Balaroud Dam.After the recognition of the activities and the environment of the field under the study with regard to the magnitude of the effects, the likelihood of the possible consequences for humans, the environment and the working equipments were identified and the classification of the risks based on the delfi method was conducted and the risk-creating factors were classified naturally, biophysically, and anthropogenically. The methodology used was analytical Hierarchy Process. After the creation of the hierarchy of risks; paired comparison matrices were formed with regard to the risk of danger and effect magnitude. Moreover, to obtain the relative and final weight of each of these factors, preferences amounts were given to the expert choice software. results show that cut and fills with the final weight of 0. 277 is the most import risk in the region. Also, drilling and explosion with the final weights of 0.60 and 0.111 are of second and third priority. Other factors are lower in priority. Measures to control and reduce risks are alsoprovided.
