Due to the continuous introduction of new building technologies, research results, and technical specifications, the design and construction process of buildings has become extremely complex, paying more attention to the sustainable development of the building itself; it not only requires close communication between project participants, but also an in-depth analysis of building performance and structure is required during the design phase. Building Information Modeling (BIM) technology has been widely used in the development of the construction industry in recent years. It can effectively realize the integration of building information, so that all parties involved in the project can work together based on the same platform, which can more effectively improve work efficiency and save resource input, lower construction costs, and ultimately achieve the goal of sustainable development. On the basis of summarizing the previous research results, this paper uses BIM technology to analyze the optimization effect of large-scale construction engineering from the aspects of information model, resource allocation and technology optimization. The analysis results provide reference for subsequent in-depth research.
