Abstract: With the domestic popularization and application of BIM technology, the large public buildings basically used the different depth of BIM applications¹. This article mainly introduces the application of BIM technology in Changsha Meixi Lake International Culture and Art Center of curtain wall engineering project in design development stage, processing stage, construction stage and operational stage of the whole life-cycle. Through the application of BIM technology, solved the difficulties of curtain wall design development, high machining accuracy requirements, construction and installation management as well as the operation and maintenance, finally realized intelligent construction of the curtain wall project.
