摘要:本文研究了大型EPC项目在设计—采购—施工一体化的总承包模式下应用BIM技术实现集成化管理。在研究了EPC项目管理模式相对于传统项目管理模式的特点和优势基础上，进一步提出了在BIM技术应用情景下的EPC改进模式。本文以桐乡市全民健身中心项目为案例，论述了大型EPC项目应用BIM技术后实现了集成化管理，并形成了EPC模式框架。案例研究实践证明，EPC改进模式下的项目BIM集成化应用解决了项目重难点问题和提升了项目的综合效益。

Abstract: This paper studies that BIM technology applies in large-scale EPC projects to realize integrated management under the general contracting mode of design-purchase-construction integration. It focuses on the characteristics and advantages of the EPC model compared to the traditional management model, and further proposes the EPC improvement mode under the background of BIM technology application. Based on the actual large-scale EPC project of Tongxiang City National Fitness Center, the paper discusses in detail the integrated management of large-scale EPC projects after applying BIM technology, and forms the framework of the EPC improvement model. The case study proves that the integrated application of project BIM under the EPC improvement mode has solved the key and difficult problems of the project and improved the overall benefits of the project.
