The application of prefabricated BIM technology in the production and demolition stages of the whole building life cycle

Abstract

With the development of engineering construction, the concept of building lifecycle management (BLM) is put forward. The building life cycle is a full cycle process starting from material and construction production, including multiple stages of planning and design, construction and transportation, operation and maintenance, as well as demolition and disposal. With the popularity of the concept of sustainable development, recycling instead of completely abandoning has become a trend. This coincides with the concept of the whole life cycle of a building. Prefabricated BIM (Building Information Modeling) is an important branch of BIM. It plays an important role in the construction of the whole life cycle of buildings due to its characteristics such as visualization, information sharing, and appropriate technology composite, especially in the production and demolition stages. Through qualitative analysis of the advantages of BIM technology and case analysis, this paper focuses on the important role played by BIM technology in the production and demolition stages. The application of BIM technology in construction animation simulation, site layout, and site planning is studied to effectively improve work efficiency and ensure construction quality. Besides, corresponding models and optimization of demolition methods are proposed based on different demolition needs. It can be concluded that in the production stage, BIM technology can be used for structural design, visual three-dimensional (3D) design, collaborative design, and optimization design, while in the demolition stage, BIM technology can be used for space management.
