What is BIM and what does it contain?

Building information modeling or building information management is based on the relevant information data of construction projects, simulating the real information of buildings through digital information simulation, and realizing the functions of project supervision, property management, equipment management, digital processing and project management through three-dimensional building models.

[ 1]? It has eight characteristics: information integrity, information correlation, information consistency, visualization, coordination, simulation, optimization and drawing.

[2]? Put the project participants such as the construction unit, design unit, construction unit and supervision unit on the same platform and enjoy the same building information model. 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.
