摘要:上海图书馆东馆是上海文化设施建设的重点项目，总建筑面积11，4951m²，是全国单体建筑面积最大的图书馆。图书馆功能空间布局复杂，体验要求高，设计难度大。东馆采用独特的大跨悬挑钢结构，施工难度大。运营期读者年接待量约400万人次，在疫情和双碳背景下，安全和高效运营压力大。因此馆方认识到传统建设运营模式已难以满足要求，提出了基于BIM建设智慧型图书馆的需求。但如何实现从设计、施工到运维的跨阶段BIM传递和数据融合，打造智慧型图书馆国内并无先例。作为东馆总承包单位上海建工四建集团依托自主研发的公共建筑工业互联网平台，研发了一系列BIM审核、转化、交付和大数据分析算法，有效支撑东馆设计、施工、竣工和运维BIM应用，提升了建造质量，提高运维效率。

Abstract: The East Building of Shanghai Library is a key construction project of cultural facilities in Shanghai. With a total construction area of 114, 951 square meters, it is the largest single building of library in the China. The functional space layout of the library is complex, experience requirements are high, thus it's difficult to design. The east library adopts a unique large-span cantilevered steel structure, which is difficult to construct. During the operation period, the annual reception of readers can reach 4 million person-times. The mechanical and electrical systems such as the book sorting system are highly specialized and energy consumption. Under the background of epidemic and carbon peaking, the operation is extremely difficult. The traditional construction and operation model has been unable to meet the demand, so the library proposed to build a smart library based on BIM. However, there is no precedent in China to build a smart library. which achieves the cross-stage model transfer and data merge from design, construction to operation and maintenance. As the general contractor of the east library, Shanghai Construction No.4(Group) Co., Ltd. developed a building industry internet platform, with a series of BIM review, transformation, delivery and big data analysis algorithms, effectively supporting the BIM application of the east library. The application of BIM has improved the construction quality and improved the efficiency of operation and maintenance.
