However, if R&M activities are not carried out properly, deterioration will occur, service of be reduced, maintenance costs increase. Hence, selecting the appropriate methods is pivotal, especially for developing countries, such as Iran, which featured by highly constrained resources. The present study aims to identify prioritize main criteria suitable Commercial Buildings (CBs), considered a profound challenge Architecture, Engineering Construction/Facility Management (AEC/FM) industry. A total 20 senior experts AEC/FM industry CBs Iran were invited participate Delphi survey solicit perceptions opinions on selection criteria. number individual identified 16, further divided into five categories: human resources, flexibility technical capability, risks, cost maintenance, together with facilities technology. Then, Fuzzy Analytic Hierarchy Process (FAHP) technique was applied Among 5 criteria, most important criterion whereas resources (HR) recognized least important.
