Site infrastructure: smooth and efficient construction process depend on a workable site infrastructure. Investing in service roads to shorten the paths for material handling or even the investment into an on-site concrete plant is positively impacting the final concrete result. Quality demand: matching and assuring the exact concrete quality demand can have a major impact on the project budget. Reviewing the demand in an early phase provides the possibility to consider the measures to be taken in the execution phase. Minimize risks: concrete joints or block joints pear a risk in regards to sealed joints and water tightness. Uncontrolled heat development in mass concrete may cause concrete cracking. In all event it will result in an impact on the project budget for repair works and maintenance. Also it may influence the durability and the service life of the dam structure. Optimize the volume of mass concrete with the corresponding pouring sequence in combination of concrete monitoring equals minimizing risks of unexpected costs. Figure 9: Wudongde Dam, China 769
