In China, the construction concept of "people-oriented" and "green environmental protection" for bridges is advocated. In order to improve the engineering quality, accelerate the construction speed and enhance the economic benefits, the application of prefabricated assembly technology in bridge construction is becoming increasingly common. The conventional construction management methods have been unable to adapt to the current construction mode of increasing speed. The multi-stage characteristics of prefabricated bridge in the analysis, design, processing, warehousing, transportation, construction, operation and maintenance are analyzed. Combined with BIM technology, the value of digital management is explored, and it is suggested that BIM technology and Internet of Things technology should be deeply integrated in the whole process of bridge prefabrication from production to completion. Thus, the intelligent construction of bridge will be further promoted to the wisdom construction.
