Building information model or building information management is the relevant information and data to the construction project as the basis, establish the 3D model of the building, to simulate the real information of building information through digital simulation. It has the characteristics of complete information, information relevance, information consistency, visualization, coordination, simulation, optimization and can be made out of the eight characteristics.
From the three basic dimensions of the BIM design process, such as resources, behavior and delivery, the specific methods and practical contents of the implementation standards of design enterprises are given. BIM (building information model) is not a simple integration of digital information, but the application of digital information, and can be used for the design, construction, management of digital methods. This method supports the integrated management environment of construction engineering, which can improve the efficiency and reduce the risk in the whole process.
BIM technology is the data of a tool used in engineering design and construction management, the relevant information through the integration of various model parameters of the project, in project planning, the full life cycle of operation and maintenance for the sharing and transfer, the engineering and technical personnel to make a correct understanding and effective response to all kinds of building information, foundation for the design team and including the construction of operating units, the construction of the main parties to provide collaborative work, play an important role in improving production efficiency, save cost and shorten the construction period!
