This bulletin has been devoted to cost savings in Dams, including 2 parts: - Identifying and mitigating existing factors detrimental to Cost Savings such as procedures, set ideas, unadapted specifications… - Technical opportunities for innovation and cost savings in the design of high and low dams built in usual conditions. The present bulletin refers to such technical opportunities for innovation and cost savings when they apply to special dams for which the specific conditions may require or favour unusual criteria or designs and / or construction methods. They may be required by environmental problems, climatic changes or local physical or economical conditions. Such specific dams may in the future require over half of all dam investments.
