Research on Data Sharing Between Design and Production of PC Components

With the rapid development of building industrialization, the integration of prefabricated building and information management has attracted much attention. In the life cycle of a prefabricated building, the stages involved are complex, the parties involved are numerous, and the data information generated is diverse and numerous, which leads to the low efficiency of data information transmission and the inability to share with each other. The reason is that there is no unified data interaction format among stakeholders at all stages. However, there are few studies on data sharing at each stage in the existing literature, and even less studies on data interaction types between design stage and production stage. To help solve the data sharing problems encountered during prefabricated building construction, this research first identified and analyzed key factors that may have a significant impact on prefabricated component data sharing. Based on the identified factors, the challenges and corresponding functional requirements for increasing data sharing are determined. Then, a data transmission method based on Revit API is proposed. Revit API transmits data to the prefabricated factory on demand to achieve seamless connection between design information and production information. Based on the WPF application under Visual Studio 2013, the PC data sharing platform is developed to realize the start and close of data sharing events. The BIM model with in-depth design can export the blanking orders and processing drawings required by the prefabricated factory through data sharing, transform the design information into production information, and complete the delivery of prefabricated components, thereby improve data sharing efficiency, and better complete the refined management of prefabricated components.
