Abstract: Aiming at the information integration of local block in the current stage of project
management and business process separates, cooperative project management problems such as
weakening the positive effect, taking a large public construction project in Tianjin as an example, the

output factor in the BIM context. Then taking participants into the same process reengineering value
chain and integrating the information transmission link of various stages between all participants to
make up for the shortcomings of traditional business processes, to improve the efficiency of workflow
transformation and to save transaction cost.

Key words: BIM, process reengineering, information value chain, cost control, progress collaborative management
