BIM is chosen mainly for practical purposes.

Building information modeling is to establish a building model based on the relevant information data of construction projects, and simulate the real information of buildings through digital information simulation. It has eight characteristics: information integrity, information correlation, information consistency, visualization, coordination, simulation, optimization and drawing.

From the three basic dimensions of resources, behavior and delivery in the process of BIM design, the specific methods and practical contents of implementing standards for design enterprises are given. BIM (Building Information Model) is not a simple integration of digital information, but an application of digital information, which can be used as a digital method for design, construction and management. This method supports the integrated management environment of construction projects, which can significantly improve the efficiency of the whole process of construction projects and greatly reduce risks.

Interpretation of BIM by Director of Engineering Quality and Safety Supervision Department of Ministry of Housing and Urban-Rural Development.

She said: BIM technology is a digital tool applied to engineering design and construction management. It integrates the relevant information of various projects through parametric models, which is shared and transmitted in the whole life cycle of project planning, operation and maintenance, so that engineers and technicians can correctly understand and respond to all kinds of building information efficiently, and provide the basis for collaborative work for design teams and various construction subjects including building operation units, which plays an important role in improving production efficiency, saving costs and shortening construction period!

The English full name of BIM is building information modeling, and the Chinese translation of BIM is: building information modeling.

As the unified standard for the application of building information model in China is still in the preparatory stage, the definition of BIM in American National BIM Standard (NBIMS) is quoted here temporarily, which consists of three parts:

1.BIM is a digital expression of the physical and functional characteristics of a facility (construction project);

2.BIM is a knowledge resource shared by * *, and it is a process of sharing information about this facility in the whole life cycle from construction to demolition, providing a reliable basis for all decisions;

3. At different stages of the project, different stakeholders insert, extract, update and modify information in BIM to support and reflect the collaborative work of their respective responsibilities.
