Building information model is a new tool in architecture, engineering and civil engineering. The term "building information model" or "building information model" was created by Autodesk. It is used to describe those computer-aided designs that are mainly three-dimensional graphics, object-oriented and related to architecture. Jerry Laiserin popularized the technology provided by Autodesk, Bently Systems and Graphisoft to the public.
BIM (Building Information Modeling) technology is a data-based tool applied to engineering design, construction and management. By integrating the data and information models of buildings, they can be shared and transmitted in the whole life cycle of project planning, operation and maintenance, so that engineers and technicians can correctly understand and effectively deal with all kinds of building information.
Providing a basis for collaborative work between the design team and the construction subjects including buildings and operating units plays an important role in improving production efficiency, saving costs and shortening the construction period.
Here, I quote the definition of BIM in American National BIM Standard (NBIMS), 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 shared knowledge resource and a process of sharing information about this facility, which provides a reliable basis for all decision-making in the whole 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.
Extended data:
BIM Grade Certificate is a national BIM skill examination organized by China Graphic Society. After passing the corresponding grade examination, Ministry of Human Resources and Social Security, China will issue the corresponding grade certificate. BIM skills are divided into three levels: the first level is BIM modeler; The second level is BIM senior modeler; The third level is BIM application designer. Take the exam twice a year, usually in June and 65438+February. This kind of certificate is the most authoritative certificate in the field of BIM at present. In the bidding documents of many domestic projects, the number and grade of "National BIM Skill Level Certificate" are clearly regarded as the standard to consider the BIM ability of enterprises.
Examination outline, as shown above.
