Contractors play the main role in the success or failure of construction projects, therefore, it is very important to determine the qualifications and selection of contractors in order to succeed in projects and reduce costs. This article was done with the purpose of evaluating and selecting construction contractors. This research is a non-experimental (descriptive) based on the objective, practical and based on the method of data collection, which was conducted in a cross-sectional survey. The target community included experts, experts and decision makers in the field of contractor evaluation in organizations and companies in Semnan. Sampling was done by targeted method and finally 10 people participated in this study. To analyze the data, the combined method of DeMetal, the process of network analysis and the best-worst were used. The findings of the research showed that the criteria of quality, management ability, financial index, technical ability, reputation and health, safety and environment are in the first to sixth priority respectively. The findings of the best-worst method have shown that quality, management ability and financial index, technical ability, safety and environment and reputation are in the next ranks. Finally, suggestions were made based on the research findings.
