In order to solve the problems of low construction efficiency, high energy consumption and low safety quality faces by many traditional girder prefabrication field, the authors of the paper applies BIM, Internet of Things, intelligent sensor and other scientific and technological means in their girder prefabrication field. An information mode of "one platform + three systems" is adopted to integrate multiple intelligent production systems based on BIM management platform through data interface development, which has successfully built the intelligent girder prefabrication field in Zhongshan for the contract section S07 of Shenzhen-Zhongshan bridge project, supporting the collaborative work of the client end, mobile end and Web end. The intelligent girder prefabrication field realizes the goals of visualization of manufacture progress of girder prefabrication, standardization of construction process, digitalization of business management, intellectualization mechanical equipment, and intellectualization of management decision. Meanwhile, the construction of BIM informatized girder prefabrication field has further promoted the development of prefabricated technology of bridge engineering in China.
