BIM for Building Information modeling, the creation of the model on the basis of the construction projects of all kinds of data, Information, and through digital Information actual real virtual simulation of the Building, rendering and 3 d model is a database, visualization, simulation, coordination and optimization, can figure out. The concept was first developed in 1975 by Dr. Chuck Eastman of the Georgia Tech College of Architecture and Computing. The concept has not received enough attention. Until 2002, autodesk formally put forward the concept of BIM, and then BIM technology began to be widely used in all kinds of construction projects in developed countries.
China introduced BIM technology in 2002, but its development was slow. Until last year, the ministry of housing and urban-rural development issued the “13th five-year” informatization development outline of the construction industry, which mentioned the application of BIM technology for many times, and many cities introduced BIM related policies, the application of BIM technology has been widely promoted nationwide. With the strategic goal of vigorously promoting prefab building in the future development of the construction industry put forward by the state, the prefab building in China has a very good development situation, which is a rare opportunity and an inevitable choice. At the same time, it also needs the close cooperation of BIM technology to accelerate the development of prefab building. BIM+ prefabricated building is also concerned in this context. Let’s take a look at the awesome aspects of BIM+ prefabricated building.
Assembly–modular BIM design
For prefabricated design phase, the earliest application in Japan, in Japan, when they design institute of architectural drawings, will also make the PC factory processing components graph directly, to the design of this step, in addition to consider the types of components, the less the better, the so-called “module”, also need to consider how mechanical production, in the future to the scene of hoisting points, how to connect between modules, connection point safety performance and waterproof performance, and so on.
Assembly–BIM model component production
The production link of factory is a special link in the construction of prefabricated building, and it is also the stage when the component changes from the design information to the entity. In order to realize automatic production of prefabricated components, the information automatic processing technology integrating information processing (CAM) and MES technology can directly import BIM design information into the central control system of the factory and convert it into production data information that can be read by mechanical equipment.
Assembly — on-site assembly of BIM components
The field assembly stage is the process of building entity develop from nothing in the whole life cycle of prefabricated building. Under the EPC project general contracting mode, bim-based sharing and collaboration of core values, with the progress plan as the main line and the BIM model as the carrier, share and integrate the design information of on-site assembly information and factory production information, and realize digital, fine and visual management of project schedule, construction plan, quality, safety and other aspects.
The combination of BIM technology and prefabricated building can play a significant role in the whole life cycle of the project, which is conducive to the fine management of the site, shortening the cycle, saving the cost, ensuring the quality and improving the level of project management. BIM technology and prefabricated building will definitely contribute to the development of China’s future construction industry.
