Analysis of Supply Chain Risks in Concrete Dam Construction

This study identifies 35 risks related to the supply chain of concrete dams, of which 25 were selected as critical risks using the Delphi method. Risks were categorized into three groups based on their sources including environmental, network and organizational risks. The Failure Mode and Effect Analysis (FMEA) method was then applied to evaluate the significance of risks in three areas of construction cost, time and quality. The results revealed that 44% of risks in the construction cost category were critical, while 21% of risks in construction time and 12% in construction quality were found to be critical. Appropriate responses to mitigate critical risks were provided, including the use of alternative supply resources, rigorous project scheduling, and diversified financial strategies. This study highlights the importance of risk management in improving project performance in terms of cost, time, and quality, and emphasizes the need for effective communication and continuous risk monitoring throughout the project lifecycle.
