This paper briefly introduces the study of Shanghai Urban Construction Group applying the Tekla Structures Software in the PC(Prefabricated Concrete) detailing design and BIM technology. Shanghai Urban Construction Group vigorously promotes the industrialization of housing, using the Prefabricated Concrete housing structure. The main components are manufactured in the factory first and then are assembled in the construction field. The traditional CAD technology based on point, line, surface and other basic geometric elements cannot generate detailed construction drawings and may contain ambiguity, incomplete information of concrete iron positioning. Therefore, the traditional method cannot meet the factory's requirement on the processing depth.Fortunately, the advanced Tekla Software can create 1:1 BIM models with a wealth of data, check the collision, automatically generate workshop drawings of PC assemblies and finally simulate the field construction.
