Based on Keqiao to Zhuji Expressway project, the models of highway, detail, beam yard andpipeline are established, and the BIM application research is carried out from the aspects of technicalquality management, collaborative management and intelligent beam yard management. Based on theBIM model, the construction scheme simulation, construction scheme optimization, formwork detaileddesign, collision detection and three⁃dimensional visualization of linear infrastructure projects are carriedout, and the collaborative management platform and intelligent beam yard management platform based onBIM are developed and applied. Practice shows that BIM technology is helpful to break the informationisland in each workflow, improve the efficiency of construction management, reduce the construction costand improve the quality of engineering construction.
