Life Cycle Cost Method for Safe and Effective Infrastructure Asset Management

Existing maintenance management systems implement periodic inspections and diagnoses perform to restore damaged facilities, making it difficult establish a long-term analytical budget plan. The Framework Act on Sustainable Infrastructure Management necessitates specific implementation plans for new items. This study proposes detailed method estimating infrastructure cost overcome the limitations of post-response system plan Management, considering performance effects in terms life cycle. was classified into following stages: analysis degradation timing by deriving curve, proper construction methods grade model each member grade, representative assessment establishment determine end-of-life members, optimal action establishing short/mid- repair reinforcement plans. proposed applied water reservoir (99 reservoirs Seoul, Korea). prediction models target were analyzed. can be decision agency is significant efficient maintenance.
