Research On BIM Application Of Construction Enterprises

BIM has entered China from the beginning of this century.First,it has been applied in design enterprises,and then extended to construction enterprises,focusing on the field of construction engineering.As the main force in the development of construction industry,construction enterprises pay more and more attention to the study and application of BIM,which has been tried in many engineering projects.However,after more than ten years of promotion,BIM is still at the primary level of development on the whole.It is mainly used by first-class or super-class construction enterprises in some large-scale buildings,and the application of the whole project cycle is relatively less.Both breadth and depth of BIM are insufficient.Therefore,it is necessary to explore the barrier factors and their relationship of BIM application in construction enterprises.This paper elaborates the research background,puts forward the research purpose and significance,and draws out the research object through literature review.In addition,the BIM theory and ISM theory are introduced to provide theoretical basis for identifying obstacles and constructing interpretative structural modeling.Then,it describes the challenges and shortcomings of traditional project management,lists the BIM application list of construction enterprises,analyzes and summarizes the typical cases of BIM application.Through literature research and Delphi method,10 obstacle factors of BIM application in construction enterprises are identified,and they are divided into three categories according to content attributes: application environment,technology method,organization management.Experts judge the binary relationship between obstacle factors,establish adjacency matrix,calculate the reachability matrix with the help of MATLAB software programming,and then divide the reachability matrix hierarchically to a four-level hierarchical structure,and construct the interpretation structure modeling.By explaining the relationship between obstacle factors through structural model analysis,two root obstacle factors are obtained,and then three suggestions are put forward from the perspective of enterprises,aiming at promoting the application and promotion of BIM in China's construction enterprises.
