Abstract: BIM visualization model is the core of BIM technology implementation. On the basis of
summarizing the advantages of BIM, this paper further analyzes its specific needs of the foundation
pit engineering construction. According to the characteristics and difficulties of foundation pit
engineering in three groups of Haihe River, BIM technology is put into the project construction, and
establish BIM model, launch the application of BIM technology, mainly for construction site layout
optimization, complex technical clarification, quality inspection, data collection, process simulation,
tec. Practice has proved that it has achieved good results.

Key words: BIM technology, foundation pit engineering, construction application
