Abstract: In order to solve the problem of low baud rate of construction quality control of traditional steel structure modular building engineering, the construction quality control method of steel structure modular building engineering is designed based on BIM technology. By defining the construction quality control content of the steel structure modular building project, the collated control data is input into the BIM assembly building information model to control the construction quality of steel structure modular building project in all aspects. Based on the analysis of the design example, the results show that the baud rate of the designed control method is obviously higher than that of the control group, which can solve the problem of low baud rate of traditional steel structure modular construction quality control.
