With the rapid development of the traditional construction industry, China's construction market is becoming saturated and overcapacity, and the global macro economy is facing uncertainty. Negatively impacted by global events and the climate crisis, the willingness of traditional architectural firms to invest in real estate, infrastructure and other projects needs to be higher. The enhancement of digital information technology has brought greater freedom and openness, and traditional architects are looking to BIM technology to stimulate creativity and build more dynamic buildings. This paper analyses the development and application of BIM technology from the perspective of the BIM+ intelligent management model. It discusses the importance of upgrading the traditional construction industry, especially in building life cycle management. Through BIM+ intelligent management, the traditional construction industry can handle the information in all project stages more efficiently and achieve the goal of resource integration. At the same time, the combination of BIM and facility management can realise intelligent operation and monitoring of building projects. This paper reviews related research and looks forward to the future research direction of combining BIM and building facility management.
