The research method was descriptive-correlational. The statistical population included all experts of Ariana Tunnel Dam Company in Tehran. Based on the Krejcie and Morgan table, the sample size was 130 participants, who were selected through convenience sampling. The instruments used in this study included the Standard Competitive Strategies Questionnaire by Jolveh Hosseini (2013), the Green Supply Chain Management Strategies Questionnaire by Valaei (2014), and the Supply Chain Questionnaire by Ebrahimi (2007). The content validity of the questionnaires was established, and their reliability was confirmed using Cronbach’s alpha coefficient. Data were analyzed using factor analysis and structural equation modeling through PLS software. The results showed that the supply chain had a significant effect on competitive strategies and green supply chain management strategies. Organizational infrastructure, information technology, interorganizational relationships, and the support system had significant effects on competitive strategies. The results also indicated that organizational infrastructure and interorganizational relationships had significant effects on green supply chain management strategies. Other findings of the study showed that information technology and the support and decision-making system did not have significant effects on green supply chain management strategies. Therefore, based on the findings, the implementation of green supply chain management strategies, particularly through strengthening organizational infrastructure and interorganizational relationships, plays an effective role in enhancing the competitive position of project-based organizations. Accordingly, it is recommended that managers of these organizations prioritize the development of infrastructure and the expansion of interorganizational relationship networks in their investment decisions.</span></p> https://journalrmde.com/index.php/jrmde/article/download/377/334
