Abstract: The Corps of Engineers currently operates and maintains 536 dams and 260 lock chambers at 596 sites. Sixty percent of these hydraulic structures are over 20 years of age, more than 40 percent are more than 30 years old, and approximately one-third are more than 40 years old. With the relatively limited number of new construction starts anticipated, many of these structures are being and will continue to be kept in operation well beyond their original design lives. The primary objective of this study was to develop quantitative information on the present condition of the concrete portions of these structures. Two computerized data bases, (A.) structure-description and (B.) damage and repair, were compiled. The structure-description data base contains basic information (location, category, age, purpose, etc.) on 766 projects. The damage and repair data base contains information on the current condition of the concrete in the Corps' civil works structures as determined through detailed reviews of over 2000 periodic inspection reports. To assist in the analysis, a number of computer programs were developed to manipulate and search the data bases. This analysis concentrated on the types of deficiencies observed, the cause (if reported), location within the structure, and degree of damage. Also, if the deficiency had been repaired, the material or technique or both that were used and the performance were analyzed. This identification and assessment of problems relating to evaluation, maintenance, and repair of concrete will provide guidance in developing and establishing priorities for research in the Repair, Evaluation, Maintenance, and Rehabilitation (REMR) Research Program.
