摘要:针对上海市东方医院改扩建工程需要保证老大楼不间断运营、机电系统专业多、施工协调难度大、后期运维管理要求高的特点，本文梳理了项目BIM综合应用的过程和成果，提出了建造运维一体化BIM应用方法。通过建造阶段BIM关键应用、建造与运维跨阶段BIM模型转换与数据集成、运维阶段BIM深入应用，构建了数据孪生东方医院新大楼，实现了建筑大数据的处理和弹性可视化。最后对BIM综合应用过程的问题进行总结和展望，提出了提升模型交付质量、改善BIM信息质量和扩大BIM运维应用范围的思考和方法。

Abstract: Shanghai Oriental Hospital renovation and expansion project is very complicated due to the demand of ensuring the uninterrupted operation of the old building, the large number of mechanical and electrical systems, the difficulty of construction coordination, and the high requirements of operation and maintenance management. The paper summarizes the process and results of the comprehensive application of BIM technology. This paper focuses on three phases of application, i.e. the critical BIM application in construction period; the BIM model transformation across different stages; and the operation & maintenance phase BIM in-depth application. Through the whole process, it delivered a digital twin of the hospital′s new building, which achieves the visualization of the process of the building′s big data and the flexibilities. Finally, it has concluded the problems during the BIM implementations and has forecasted the future perspectives, which offers method to improve the qualities of model delivery, to improve the quality of information, and to expend the scope of the BIM implementations.
