Preliminary Exploration On The Research And Achievements Of BIM System In China

With the development of industrial architecture,smart city and digital China accelerating,BIM is at the critical moment of systematization to drive the development of construction industry.On April 20,2020,the national development and Reform Commission made authoritative interpretation of "new infrastructure".The new infrastructure is characterized by "digital infrastructure".BIM is an important part of CIM,and it keeps accumulating and updating to ensure the dynamic update of CIM.CIM is the key technology of intelligent park and supports the intelligent management of urban planning and construction.The construction of smart city is the foundation of Digital China and smart society.In july2020,the guidance on the coordinated development of intelligent construction and construction industrialization emphasized the application of BIM Technology with independent control.In addition,in the international situation,the list of trade war entities has brought a blow to China’s construction industry.Because of the absence of BIM system with independent intellectual property rights,domestic designers can only use foreign BIM software.Through investigation and research,there are some problems in BIM software,such as safety hidden danger,non-compliance of specifications and differences in usage habits.The domestic BIM system for R &D of independent intellectual property is the decisive factor in the development of construction industry under the background of new infrastructure construction.PKPM BIM,a domestic BIM design software being developed by China Academy of architecture Sciences,has basically met BIM application standards.Based on the domestic BIM system,the research direction is the good and intelligent building forward design,and BIM architecture design products are the research objectives.From the perspective of Chinese architectural designers,this paper explores the research and development ideas of BIM architecture specialty which conform to local design habits,adapt to national standards and specifications,and adopt data driven 3D design thinking and intelligent automation.The first chapter is to clarify the deficiency of the current research through the review and sorting of the relevant literature at home and abroad.This paper expounds the background,purpose and significance of this paper,and then determines the content and method of this paper,and finally combs it as the research framework.The second chapter summarizes the development of BIM at home and abroad,and draws on the advantages of the development of BIM abroad,avoids the development of BIM abroad.Combined with the analysis of the domestic BIM development status and shortcomings,it expounds the necessity of domestic BIM research and development is extremely far-reaching significance.Finally,the research and development status of domestic BIM is summarized,and the necessity of domestic BIM development is expounded.Chapter three analyzes the development pain points,BIM competitive products and domestic existing resources,obtains the demand,and then combines the analysis of the research data,and obtains the development strategy of domestic BIM,the application process framework of domestic Bim and the full professional integration framework of domestic BIM,which lays a good foundation for the research and development of construction specialty.The fourth chapter is the core content of this paper,based on the domestic BIM system,the detailed design content of the architecture specialty.First,the article expounds the guiding principles of product design of Architectural Specialty,and then explores the product design framework of BIM architecture from abstract to concrete.The fifth chapter is the sample usability test stage,which is divided into two parts.The first part is the application process and result analysis of two projects,and the second part is the BIM application capability maturity test based on post use evaluation.The final test results of the research results are that the BIM certification standard is met.Chapter six summarizes the theoretical research and practical application of this paper,which is divided into three parts.The first part summarizes the research results of this paper,the second part summarizes the shortcomings of this study,and the third part prospects the follow-up research.
