Abstract: To realize the BIM forward design of industrial engineering construction projects, it is necessary to establish a set of process equipment family database with complete system. Through analyzing the construction of the existing process equipment family database, this paper studies the information coding system of rail transit assets in Beijing and transplants it into the corresponding rail transit engineering construction projects to establish the coding system of process equipment family database construction. Moreover, this paper puts forward a set of basic methods to establish and manage the enterprise level process equipment family database, as well as the specific application direction of the family database system and its code in process BIM forward design, which provides a reference of the construction system and application of BIM forward design family database for design enterprises.
