Abstract: For the design of the Suapiti hydropower station, the 3DEXPERIENCE platform of the Dassault Systemes is for the first time introduced to implement the forward collaborative design. During the whole design process, all BIM applications and design results are integrated on the 3DE platform by using ENOVIA, which ensures the most optimized and secured design results, improves the quality of design products, and forms continuous deliverable digital engineering assets. Combining with the secondary development of Composer, an information management system for design is independently developed to lightweight the BIM model for better management on the BIM model and related site design documents at the construction site, which will significantly improve the project information management capability.
