摘要:EPC总承包项目通常具有体量大、工期长等特点，而装配式建筑又对设计的精细化、项目信息传递的准确性提出了挑战。BIM技术作为建筑信息数字化的载体，具有设计表达数字化、数据信息协调化、信息传递连续化、数据功能多样化、信息调用便捷化可控化等特点。本文以重庆市腾讯大型双创社区为例，探索BIM技术在大型EPC装配式项目前期方案确定、设计阶段中的应用。结合EPC项目管理需要，将“前策划，后评估”的管理理念贯彻到项目中，并通过BIM技术的应用提升设计质量和实现造价控制，并探索了BIM与新技术的结合应用。为本项目后期施工和运维阶段打下了坚实基础，为BIM技术应用于EPC项目设计提供了宝贵经验。

Abstract: The EPC contracting projects usually have the characteristics of large volume and long construction period, while the prefabricated buildings challenge the precision of design and the accuracy of project information transmission. As the carrier of building information digitalization, the BIM technology has the characteristics of digitalization of design expression, coordination of data and information, continuity of information transmission, diversification of data functions, and convenience and controllability of information transfer. Taking the Tencent large-scale double-venture community project in Chongqing as an example, the paper explores the application of BIM technology in the early stage scheme determination and design stage of large EPC prefabricated project. According to the needs of EPC project management, the concept of "pre-planning, post-evaluation" was implemented in the process of the project, improving the design quality and achieving the cost control through the application of BIM technology, and the combination of BIM and other new technologies was explored as well. The study lays a solid foundation for the later construction and operation stage of the project, and provides valuable experience for the BIM application in process of design for EPC projects.
