Abstract: With the continuous development of prefabricated pipe gallery and BIM technology, and in order to integrate BIM technology and prefabricated pipe gallery, this paper takes a practical prefabricated pipe gallery project as an example to analyze the application of BIM technology in its design stage. The project practice verifies that, by applying the BIM technology to design prefabricated pipe gallery, design errors are effectively reduced, design model is obviously optimized, and the project quality is significantly improved, which can provide reference for similar projects.
