The paper investigates the integration of BIM, Digital Twin technologies, Extended Reality (XR), and graphical interfaces for facility management and maintenance support in complex buildings. The research proposes a methodological framework describing the evolution of BIM models from physical twins to as-built, as-is, record, and FM-oriented digital twin models. The study explores the use of desktop graphical interfaces, 360° photo comparison systems, augmented reality, and virtual reality applications to inspect, compare, update, and manage BIM-based information. The proposed workflow aims to improve decision support systems for maintenance operations, data reliability, and operational awareness in the AECO sector through interactive and immersive visualization environments.
