Abstract: Infrastructure, the backbone of a developing nation, heavily relies on Reinforced Cement Concrete (RCC) for its construction. While RCC structures have a designated lifespan (50 years for buildings, 80-100 years for bridges and dams according to IS 456). The longevity of a RCC structure depends on proper and timely maintenance. This research addresses the challenges of managing an 85-year-old college building. A thorough survey identified various forms of structural distress and their root causes. Subsequently, repair methodologies were developed based on PWD SSR guidelines. To improve efficiency, an automated data entry sheet was created to streamline cost estimation. The effectiveness of the repair strategy was validated through non-destructive testing. This research offers a cost-effective and time-saving solution for maintaining aging infrastructure. The combination of the automated data entry sheet and the repair methodology paves the way for efficient upkeep of existing structures.
