摘要：Building Information Modeling in Precast Concrete factory should consider the split design and production as a whole, so we should pay attention to import the production information into MES and achieve enterprise level application. This paper studied two methods of importing production information to Manufacturing Execution System, namely DXF drawing and U file. This paper studied how to match information of DXF drawing with MES’s layer, text information and title bar. This paper also studied the correct format of U file and the information that can be resolved by MES. The feasibility of this two methods was verified through the prefabricated building project “Jin-an Hong Bao 7#”, and the types of prefabricated components, information quality, efficiency and cost of the two methods are compared. Dxf drawing is able to cover all kinds of precast components, easy for new comers to master, but the drawing efficiency is low. Currently, U file only supports composite floor slab, and it has a long training period, but it also has extremely low error rate and extremely high drawing efficiency.PC factory should continue to improve u file, which can greatly improve work efficiency and reduce engineering errors.
