For the construction of the Three Pavilions in One project of Fuyang museum, art gallery and archives, to build up the roof structure is extremly complex with high quality requirements promoted, and new technologies and techniques should be adopted. The roof is constructed as a hyperbolic hollow floor, which is in irregular shape and difficult in construction. BIM technology is applied to solve the construction difficulties, including creating 3D information models, extracting engineering information, determining the scaffold pole elevation, optimizing the template layout, and etc. Also, the BIM technology, combined with the enterprise project management system, is able to achieve multi-aspect information management of the project. The engineering practice shows that this method is effective and has broad application prospects. Also, it can provide theoretical guidance and technical reference for similar projects.
