The main large inspection done through with field investigation and data processing to check the condition of the dam safety in terms of structural, hydraulic, seepage and operational readiness in both normal and extraordinary conditions. Additionally, it is to monitor and evaluate the dam security which consist of the strenghtness of the dam structure, monitoring and operation and maintenances systems and the early warning system of the dam. The main report contains the results of the evaluation and analysis of main dam and its complementary building, hydrology, geology,hydro mechanical and electrical equipments,environmental, dam stability and abundance, sedimentation, operating and maintenance systems, reservoir survey and emergency action plans Keuliling Dam (Multi Karadiguna Jasa Consultant, 2013). 3.2. DAM INSPECTIONS RESUME The result of major inspection work that was done for 8 (Eight) months start from 23rd March to 19th November 2013 had shown that the main dam of Keuliling Reservoir and its appurtenance in a proper condition. The dam crest has no significant settlement, seepage, crack, joints, sliding and gully erosion but a little deflection and debris. The seepage measurements in downstream area that using a v-notch was found that this gauge had a broken telemetring tool. The spillway of the dam was having no substantial crack, debris, or erosion condition. The intake house of Keuliling Reservoir still in appropriate condition, however it is recommended that there should be an immidiate treatment in a structure of the tunnel due to its leaking situation in the joint concrete part. Also, the tunnel should be given a protective paint to maintain the quality of tunnel construction. The main report for the work of the Large Dam Inspection is the result of the implementation of the inspection work. The main report contains reports of the evaluation and analysis of Keuliling dam and its appurtunance included several evaluations as follow; - Visual Evaluation of Dam and Complementary Building; - Hydrological Evaluation and Analysis; - Evaluation and Analysis of Technical Geology; - Evaluation and Analysis of Hydro mechanical and Electrical Tools; - Evaluation and Analysis of Dam Stability and Abundance; - Evaluation and Analysis of Instrumentation on Body Dam; - Evaluation and Analysis of Environmental Condition of Reservoir; - Evaluation and Analysis of Sedimentation Reservoir Survey; - Evaluation and Analysis of Operating and Maintenance Systems; - Evaluation and Analysis of Emergency Action Plans; - Evaluation and Analysis of Dam Security. It was proposed that the Keuliling Reservoir is provided an emergency control facilities such as gate shaft, controling system from mechanical and electrical tools and a particular emergency road. Geological condition of Keuliling Reservoir in the main dam, saddle dam, the toehold dam in right and left area, spillway, outlet channel, and its surrounding area had no degradation or 1318
