[0002] With the rapid development of assembly building, construction efficiency, installation precision and cost control have become the focus of the industry. Traditional assembly wall construction mainly relies on manual hoisting and positioning, which has problems such as large deviation, long adjustment time, and dependence on worker experience, which seriously affects the construction quality and progress. Especially in high-rise buildings or complex structure projects, the precision requirement of wall installation is higher, and the traditional method is difficult to meet the needs of industrialized construction. It guarantees the quality of the building, but in the construction process, its construction progress is restricted by many factors such as the production speed of the manufacturer's components, transportation methods, etc. Changes in the construction process are not conducive to the production of components, and during the installation process, problems such as "mistakes, omissions, collisions, and defects" may occur. The application of BIM technology can effectively improve the inventory and site management of prefabricated components and improve the efficiency of construction site management. Assembly building has high degree of mechanization and complex construction technology. Currently, BIM technology is mainly used to optimize construction processes and construction schemes, thereby achieving high-quality installation. In the assembly building construction process, the data model of BIM technology can be used to track and monitor the implementation of the construction progress, and dynamically manage the progress and cost.
