In order to improve the quality of integrated pipe network design, reduced the illogical arrange and conflict in the blueprint of the integrated pipe network, and provided a zero conflict blueprint for pipe network construction. Based on the 3D information technologies, building aided design module of the metro station integrated pipe network aided construction and management system. Through the parameterized modeling technology, 2D information of the metro station transformed to 3D information model, realized the functions of property management, finding and modify conflict for 3D information modeling. Finally, the system was applied in Ningbo Metro Line 2, solved the problem of conflict in design, provided a collaborative design system for Design Institute.
