What software is BIM?

The full English name of bim is "Building Information Modeling", which means building information model. It is a new tool software for architecture, engineering and civil engineering; it is used to describe those object-oriented, three-dimensional graphics-based, Computer-aided design related to architecture.

Building Information Modeling (Building Information Modeling), referred to as "BIM", is a new tool for architecture, engineering and civil engineering. The term Building Information Modeling or Building Information Modeling was coined by Autodesk. It is used to describe those computer-aided designs that are mainly three-dimensional graphics, object-oriented, and architecture-related. The concept was originally developed by Jerry Laiserin to promote the technology provided by Autodesk, Bentley Systems Software, and Graphisoft to the public.

BIM (Building Information Modeling) technology was first proposed by Autodesk in 2002 and has been widely recognized by the industry globally. It can help realize the integration of building information, from building design, construction, and operation. Until the end of the building's life cycle, all kinds of information are always integrated into a three-dimensional model information database. Design teams, construction units, facility operation departments, owners and other parties can work collaboratively based on BIM, effectively improving work efficiency and saving resources. , reduce costs to achieve sustainable development.

The core of BIM is to establish a virtual three-dimensional construction project model and use digital technology to provide this model with a complete construction project information database that is consistent with the actual situation. This information base not only contains geometric information, professional attributes and status information describing building components, but also includes status information of non-component objects (such as space and motion behavior). With the help of this three-dimensional model containing construction project information, the degree of information integration of construction projects is greatly improved, thereby providing a platform for project information exchange and sharing for relevant stakeholders of construction projects.

BIM has the following characteristics:

It can be applied not only in design, but also in the entire life cycle of construction projects; using BIM to design is digital Design; the BIM database is dynamically changing and is constantly being updated, enriched and enriched during the application process; it provides a platform for collaborative work for all parties involved in the project. my country's BIM standards are being researched and formulated, and the research team has achieved initial results.

BIM (Building Information Modeling) technology is a data-based tool used in engineering design, construction, and management. Through the integration of digital and information-based models of buildings, it can be used in the entire project planning, operation, and maintenance process. Sharing and transmission during the life cycle enables engineering and technical personnel to correctly understand and efficiently respond to various building information, providing a basis for collaborative work for the design team and all construction entities including construction and operating units, and improving production Play an important role in efficiency, cost saving and shortening of construction period.

The definition of BIM from the American National BIM Standard (NBIMS) is quoted here. The definition consists of three parts:

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

(2)BIM is a shared knowledge resource, a process of sharing information about the facility and providing a reliable basis for all decisions in the entire life cycle of the facility from concept to demolition;

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