Supervisor Professor at the Syrian Virtual University, Damascus, Syria Samer Darwish This research addresses the challenge of creating accurate 3D BIM models for existing buildings using laser scanning and point cloud technologies, enabling effective documentation, management, and use in mechanical system maintenance. The study also aims to assess the integration effectiveness of these technologies with BIM software in facility management, shedding light on challenges related to workforce and resource shortages for their implementation. It emphasizes the importance of raising awareness about the benefits of using point clouds and their applications to enhance maintenance operations and building sustainability, thereby enhancing the ability to make informed technical and economic decisions to achieve comprehensive maintenance goals. 2025 2025 12 19 10.54216/IJBES.100202 https://www.americaspg.com/articleinfo/22/show/3499
