This study uses a fuzzy analytical hierarchy method to help people make decisions about how to plan maintenance for older reinforced concrete buildings (ORCB). Visual inspections, in addition to a variety of criteria and sub-criteria, will be used to accomplish the goal of classifying the level of deterioration that has occurred to the administrative building that serves the city of El Malah. The historical context of the building, environmental circumstances, structural capability, and professional participation are the key aspects that were evaluated in this study. After that, these components are broken down further into a number of other sub-factors. The calculation of weights (Wi) using Buckley's fuzzy geometric mean approach is what determines the relevance of each component and sub-factor individually. After that, scores from experts are allotted to each criterion and sub-criterion, and these ratings are then used to compute the comprehensive score (CS), which represents the ORCB's level of deterioration. The EMS-98 rating system is used to assign an overall rating to reinforced concrete structures based on the overall ratings. In general, this methodology offers a way that is both organised and objective to evaluate the deteriorating condition of ORCBs. As a result, it enables informed decision-making in the process of planning maintenance.
