BIM Technology Application Framework Based On User Requirements Analysis

With the rapid progress of the construction industry, building information modeling technology (abbreviated BIM) appears and lead the construction industry trend, it has become an important research in the field of industry sectors to research engineers and technicians, however, BIM technology starts from abroad, after the technology introduce to China, there are a lot of exclusions come out, chines standard can not directly borrowed abroad BIM standard, which makes severely difficulty on the BIM application of domestic projects.Application of BIM in china needs to make a viable domestic BIM standard system as a support as the basis.Studying on number of documents about BIM standard, user demand for BIM technology is the starting point, to analyz the BIM standard application framework consisting of content and combine with practical examples of the application. Which demonstrates the BIM standard framework is viable.The main content of the article:(1) Review the current research on BIM standard.(2) From the perspective of implementation of the application of BIM software tools to analyze the classification and tiering software.(3) Construction and engineering characteristics of the different users involved in content analysis based on the requirements of different users to find content for BIM technology, and the requirements of content are classified, as a foundation for further study of BIM standard.(4) Make the summary of the BIM standard application framework consisting of content, content and composition were analyzed in-depth research, detailed BIM standard framework components content.Article main conclusions are:(1) The implementation of BIM technology applications rely on software support, implementation of BIM software requires the formation of an ecosystem of many interrelated, software ecosystem function in accordance with the role can be divided into internal and external ecosystem, mainly established by the internal model class software components and external applications according to specific points for preliminary design BIM software, BIM visualization software,2D drafting and drawing, BIM software, BIM model comprehensive testing software, BIM deepen design software, BIM green energy analysis software, Multidimensional management software eight categories, according to their use of user requiremnets matching combinations.(2) BIM technology comes from the requirements of users, according to different users for requirements and application content BIM technology to classify into visual virtual display,3D simulation construction, target dynamic control, integrated information management, collaborative work platform, model checking six basic content.(3) Articles of BIM technology application framework composition of analysis, the overall framework of BIM technology application content by the BIM technology processes, BIM data management, collaborative work platform, organization and management, interactive information requirements consisting of five areas, and Each frame covers in particular have a clear understanding of the content. The BIM technology application framework covers a wide range of BIM have global application implementation guidance.(4) Analysis of actual cases through the application of BIM technology application framework to validate, in the form of application structure in line with the BIM case, BIM application frame content in the form of articles drawn article obtained BIM technology application framework covering the entire Application content cases, confirmed the feasibility of the BIM technology application framework.
