This article is about what software bim refers to. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The English full 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 computer-aided design that is based on three-dimensional graphics, object-oriented and architecture-related.

Building Information Model (Building Information Modeling), abbreviated as "BIM", is a new tool in architecture, engineering and civil engineering. The term Building Information Model or Building Information Model was coined by Autodesk. It is to describe those three-dimensional graphics-based, object-oriented, architecture-related computer-aided design. At the beginning of this concept, Jerry Laiserin promoted the technology provided by Autodesk, Bentley Systems Software and Graphisoft to the public.

BIM (Building Information Modeling) technology was first put forward by Autodesk Company in 2002 and has been widely recognized by the industry all over the world. It can help to realize the integration of building information. From the design, construction and operation of buildings to the end of the whole life cycle of buildings, all kinds of information is always integrated into a three-dimensional model information database. Design team, construction unit, facility operation department and owners and other personnel can work together based on BIM to effectively improve work efficiency, save resources, reduce costs, and achieve sustainable development.

The core of BIM is to provide a complete and consistent construction engineering information base for this model by establishing a virtual three-dimensional model of building engineering and using digital technology. The information base contains not only geometric information, professional attributes and state information describing building components, but also state information of non-component objects (such as space, motion behavior). With the help of this three-dimensional model containing construction engineering information, the degree of information integration of construction engineering is greatly improved, thus providing a platform for engineering information exchange and sharing for stakeholders of construction projects.

BIM has the following characteristics:

It can be applied not only in the design, but also in the whole life cycle of the construction project; the design with BIM belongs to digital design; the database of BIM is dynamic, which is constantly updated, enriched and enriched in the process of application; it provides a platform for project participants to work together. The BIM standard of our country is being studied and formulated, and the research group has achieved phased results.

BIM (Building Information Modeling) technology is a kind of data tool applied to engineering design, construction and management. Through the integration of building data and information model, it is shared and transmitted in the whole life cycle of project planning, operation and maintenance, so that engineers and technicians can correctly understand and efficiently deal with all kinds of building information. Provide the basis for collaborative work for the design team and all parties, including construction and operation units, and play an important role in improving production efficiency, saving costs and shortening the construction period.

Here, we quote the definition of BIM in the American National BIM Standard (NBIMS). The definition 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 shared knowledge resource, a process of sharing information about the facility and providing a reliable basis for all decisions in the entire life cycle from concept to demolition.

(3) at different stages of the facility, different stakeholders support and reflect the collaborative work of their respective responsibilities by inserting, extracting, updating and modifying information in the BIM.
