Construction projects play an important role in the growth of GDP and economic progress of countries. However, these projects always face a diverse range of risks. If these risks are not identified and evaluated properly at the beginning of the project, and appropriate risk response strategies are not selected considering them, they become the causes of claims that can be the basis for disputes. This research presents a claim cause – claim request model to identify and evaluate risks, and applies it to the design-bid-build construction projects in the Iranian Central Oil Fields Company. After conducting a thematic analysis with 10 semi-structured interviews, 32 claim causes and 26 claim requests of the contractors were identified. Then, by estimation of the probability of occurrence of causes and requests, and the potential loss of each request by the experts, the claim cause – claim request matrix was formed. The analysis of this matrix by Bayes' rule led to the identification of the most preferred claim causes and claim requests. The findings of the research can be the basis for adopting risk response strategies. The claim-based opinion-experts model of this study helps owner to identify and evaluate the risks that lead to the contractor's claims, and provides the owner with a suitable basis for choosing response strategies to these risks.
