What is BIM and what does it contain _ What does BIM mean?

Building information modeling or building information management.

Based on the relevant information data of construction projects, the real information of buildings is simulated by digital information simulation, and the functions of project supervision, property management, equipment management, digital processing and project management are realized by three-dimensional building model.

[1] has eight characteristics: information completeness, information relevance, information consistency, visualization, collaboration, simulation, optimization and plotting.

[2] Project participants such as the construction unit, design unit, construction unit and supervision unit will enjoy the same building information model on the same platform. It is conducive to the visualization and refined construction of the project. BIM is no longer just a software like CAD, but a management tool, which is an important tool to realize the refined and information management of the construction industry.
