The Three Gorges Dam is potentially one of the largest, if not the largest infrastructure projects completed in the 21st century. Clearly, there were a number of key risks that the construction operation faced in completing this project. Based on your research on the Three Gorges Dam, describe in detail six of the specific risks encountered across the spectrum of topic areas (e.g. technical, environmental, societal impact, operations, etc.) that were identified either prior to or during the construction phase. Describe the specific steps that were taken to mitigate these six risks and how successful those mitigation strategies were. Identify any problems that have resulted since completion of the dam in 2006 for the six risks that you identify. Discuss the methodology you recommend for identifying and mitigating these risks factors on future infrastructure projects.
