Construction of the Hungry Horse Dam in Montana.

"Construction engineers need to be aware of design philosophies and assumptions as to site conditions and function of project structures, and must understand the designers' intent concerning special technical provisions in the specifications. Identified preconstruction activities should include the orientation of construction engineers to the site specificity of the design and to the close communication requirements with all concerned engineering disciplines during the construction process. For major projects, there should be periodic meetings between design and construction engineers to discuss upcoming construction activities. Also, during the initial stages of important construction activities, the construction engineers should request site inspection by the design engineers to assure construction procedures are in accordance with design requirements." [1]

"The programs should include frequent and mandatory inspections during construction to confirm that site conditions conform to those assumed for design or to determine if design changes may be required to suit the actual conditions. A major requirement is inspection and approval of the dam foundation and foundation treatment before placing of dam materials. Final design inspection of the construction should include complete project surveillance and testing of operating equipment."[1]
