Building Information Modeling (BIM) offers advantages such as 3D visualization

full-process information integration capabilities

and simulation optimization functions

making it widely adopted in design and construction phases. However

its application in the operation and maintenance (O&M) stage remains limited. Meanwhile

through research and summary of the platform

it is found that the platform has problems such as poor interaction between architectural space and Internet of Things devices

poor interface interactivity

and single platform functions. To address these issues

this study combines cutting-edge technologies such as cloud computing

big data and data analysis to study a building operation and maintenance management platform based on BIM. The paper introduces key technologies

including BIM data processing

software-hardware systems

and data analysis

applies the platform to actual projects

and finally puts forward the existing problems and improvement suggestions of the platform.
