Requirements for Environmental Engineering Concrete Structures) and the CBC (California Building Code) as applicable to the design and/or retrofit of potable water storage reservoirs. The Consultant's analysis shall take into account all structural components including floors, walls, columns, roofs and the entire tank lid including all entry portals. Report on the condition of expansion joints and sealants. Report on the condition of all appurtenances including floats, overflow piping, inlet and outlet piping, drains, ladders, etc. Recommend locations for destructive (core samples) testing of reservoirs with applicable analysis types. Upon approval from the City, commence with testing and proper repairs for the sample being selected. If non-destructive methods of testing can be recommended as alternatives, please provide a comparison with the corresponding core sample test and the advantages and disadvantages of one test over the other. Consultant shall perform a reservoir freeboard evaluation using both the current ASCE 7 requirements and the current requirements of AWWA D110. Compute and recommend safe water level recommendations based both on freeboard equations and the structural conditions of the tank walls. Corrosion Assessment Element: Once the initial corrosion assessment has been completed and appropriate additional testing, where warranted, has been performed, the Consultant shall prepare a "repair strategy" with budget -level construction costs for mitigating existing and anticipated corrosion problems in the reservoir, which shall include a report on the conditions of the coatings protecting all steel appurtenances (e.g., inlet/outlet, overflow and drain piping, etc.). That strategy shall include appropriate recommendations for replacing coatings, replacing corroded metal appurtenances with fiberglass, polyethylene, PVC, polypropylene or FRP appurtenances, and/or adding cathodic protection as needed. Security Assessment Element: Prepare an overview assessment of reservoir tank security. This assessment shall include an overview of the adequacy of existing tank security measures including padlocks, fencing, gates, tank vents, access points, hatches, cages and cameras and shall include recommendations to upgrade due to age or foreseen failure. This assessment is not intended to provide an exhaustive and detailed evaluation of other security apparatus. Summary of Conclusions and Recommendations: The Consultant shall provide a baseline evaluation that summarizes the general condition of all the reservoirs considered in this study. The conclusions shall prioritize any deficiencies found based upon consequence of failure and likelihood of failure criteria. This shall be done on a system wide level (all reservoirs evaluated) as well as on a site specific level.
