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.

由于不断引入新的建筑技术，研究成果和技术规格，建筑物的设计和建造过程变得极为复杂，更加关注建筑物本身的可持续发展。它不仅需要项目参与者之间的密切沟通，而且在设计阶段还需要对建筑性能和结构进行深入分析。近年来，建筑信息模型（BIM）技术已广泛应用于建筑行业的发展。它可以有效地实现建筑信息的整合，使项目涉及的各方可以在同一个平台上协同工作，从而可以更有效地提高工作效率，节省资源投入，降低建设成本，最终实现可持续发展的目标。在总结以往研究成果的基础上，本文采用BIM技术从信息模型，资源配置和技术优化等方面对大型建筑工程的优化效果进行了分析。分析结果为后续的深入研究提供参考。
