This paper summarizes the value of refined management in construction projects

and elaborates in detail on the application of key technologies such as pile foundation construction

steel structure construction

and concrete construction in construction projects in combination with engineering cases. Meanwhile

a refined management strategy for on-site engineering construction is proposed around BIM technology

the Internet of Things and information technology means. The results show that refined management is conducive to reducing the rework rate

shortening the deviation of the construction period and reducing material loss.
