In order to further sort out the application process of BIM technology in building engineering construction and better ensure the construction quality of building engineering,this paper takes the first-stage construction project of a provincial maternal and child health hospital as an example to establish a BIM model,and expounds the practical application of BIM technology in the construction quality management of the project from three stages:before construction,during construction and after construction.The results show that BIM technology can comprehensively manage the construction quality of construction projects and significantly improve the construction quality and efficiency of construction projects.
