Risk Evaluation Of BIM Technology Application In Construction Engineering Projects Based On SNA

In recent years,with the acceleration of urbanization development,the construction industry is also developing rapidly in the information technology,the building information model(Building Information Modeling,BIM)application is becoming more and more widely,the government also introduced a lot of related policy,the application of BIM technology is the result of the development of The Times,in the process of development will inevitably bring a lot of risks,BIM technology in the construction project development,so seek corresponding risk prevention measures become particularly critical.Starting from the relationship between risk factors,using social network analysis,with the help of UCINET software to build risk network model,in the construction project BIM technology application risk identification and research analysis,so as to find its core risk factors and key risk transmission path,hope to be able to provide new ideas and ideas for the construction project management.Through the literature review method,Extensive review of the literature,Summarize the30 main common risk factors,And then,by using the Delphi method,To consult with the experts,Finally,25 risk factors for BIM technology application were compiled,And then large flood of questionnaires to investigate the relationships between risk factors,Organize the findings,Study and analysis of the survey findings,Constructs an adjacency matrix of the risk relationships,Then,based on social network analysis,Construct a social network model,And from the perspectives of overall network density,block model and individual network,Finally,the core risk factors and the key risk transmission path are summarized.Finally,according to the research analysis of the core risk factors and key path,put forward the corresponding preventive measures,and use the social network analysis,the core risk factors and path of the model,found in construction engineering BIM technology application risk model index have significantly reduced,it also affirmed the social network analysis for application in the construction of BIM technology application risk research feasibility.
