As the number of prefabricated concrete buildings increases, BIM technology has been practiced more, and the combination of prefabricated concrete buildings and BIM now seems inevitable. This paper mainly introduces the overall application solution of Shanghai Nanxiang Chenxiang Road Station complex project BIM. Before the PC component is produced, the BIM model is applied for deepening design. Through the secondary development of Revit, the steel bar information is automatically exported and quickly input into the steel bar processing equipment to realize the digitalization and batch processing of steel bar. Before PC members enter the construction site, BIM disclosing is implemented to the complicated construction nodes of prefabricated cast-in-situ joint to reduce the site rework. In the process of PC component construction, the progress, quality, safety, business and other management based on BIM are carried out through the information platform independently developed to realize the deep integration of BIM technology and site management. The application shows that BIM technology in PC project plays a significant role in construction schedule and quality management and multi-participant coordination management.

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.
