Reduction of the Bim Dimension of the Full Life Cycle of Building and Facilities
Statement of the problem. The subject of the research is information models of a complete life project in the sector of architecture, design and construction and maintenance of buildings and structures. The purpose of the research is to optimize BIM technologies by means of building a model based on a discrete vector data description. Results. The main obstacles to the widespread introduction of BIM technologies and procedures for the full life cycle of a construction project in the practice of the construction complex of the Russian Federation throughout the entire life cycle of the project, including the stages of construction, operation and disposal, as well as global trends in this process have been analyzed. The method of BIM dimension reduction based on discrete vector data description is formulated. The technology of forming a hierarchical dynamically added and updated information base BIM taking into account the possibility of its aggregation has been developed. The suggested algorithms are implemented in the shell of a relational database management system. Conclusions. BIM dimension reduction based on a discrete vector description of data allows one to completely solve the problems of both designing and updating the BIM information base, and its transfer between project participants. BIM data formats are determined by the stage of the complete project life cycle. Fully functional for the stage of determining the scope of work on a project, BIM is one-dimensional and is simply determined by the vector of clusters of a lower degree of integration, which allows one to completely overcome all of the obstacles to the widespread introduction of BIM technologies and procedures of a full life cycle of a construction project into practice. The optimal shell for the implementation of BIM technologies are relational databases.
