Abstract:Through a systematic analysis of the influencing factors of BIM application in the smart construction site system, in order to promote the application of BIM technology in the smart construction site system, this study takes the influencing factors of BIM technology application in the smart construction site system as the research object, and uses the ISM research method to conduct research and analysis on 13 secondary indicators under the five primary indicators of technology, management, personnel, economy, and environment; And adopting the method of analytic hierarchy process, the main factors affecting the application of BIM in the smart construction site system were re analyzed, and it was found that technical deficiencies were the main factor affecting the application of BIM in the smart construction site system, and management difficulty was the secondary factor. This provides suggestions for promoting the development of BIM application in the smart construction site system.
