"Quality construction is critical to dam safety. Construction personnel must be constantly alert to recognize and recommend the possible need for adjustments in the design, construction materials, and construction practices to properly provide for actual conditions encountered. The essential aspects of the construction program include:
- "Keeping construction engineers and inspectors informed of the design philosophies, assumptions, and intent of the designer with regard to foundation excavation and treatment, to the usage and processing of construction materials, and to the design concepts associated with the construction of embankments and concrete structures and with the installation of mechanical and electrical equipment
- "Keeping construction engineers and inspectors informed of the field control measures and tests required to ensure quality construction
- "Maintaining an adequately staffed and equipped materials laboratory at the dam site to meet the field testing requirements
- "Providing a formal plan for construction inspection to ensure that each facet of essential work is accomplished in multishift operations
- "Giving the Project Construction Engineer the authority to suspend work until all site conditions different from those anticipated are evaluated and the necessary design or construction changes are implemented
- "Inspection and acceptation of critical work stages, by the appropriate engineers or geologist (design and/or technical review personnel)
- "Keeping a job diary and documentation that provides a complete history of the work
- "Providing mapping and photographic documentation of the construction progress and of significant events; e.g., geologic maps and photographs of final treated foundation." [1]
