Construction process reengineering (CPR) is used to reengineer the construction process of engineering project by using the thought and method of business process reengineering (BPR) to improve the efficiency of engineering construction. CPR theory provides improvement direction for construction project information management: On the data-oriented and function-oriented bases, it can realize the support of engineering construction project management information system for management process, and realize the objective of information integration and knowledge sharing under the premise of process optimization. The paper makes research on the process and method of construction project management process reengineering based on CPR theory, puts forward design thought for engineering construction project management information system based on CPR theory, and uses J2EE technology to set up information platform to realize the support for construction management process.
