The invention discloses a constructional engineering project management system which comprises a supervisor platform, a government department terminal, a design unit module, a construction unit module, a safety supervision module, a quality supervision module and an engineering acceptance module, and the process flow comprises engineering project design, engineering project approval, engineering project construction and engineering project acceptance. According to the invention, engineering project management and engineering data informatization are realized through four steps of process flows; the system inputs all data related to the engineering project into the system for informatization. A data format is unifiled. Information data is stored in each system part. The supervisor platformsupervises the work of other modules, and the government department terminal supervises the supervisor platform, thereby supervising the whole system, achieving the monitoring of the government for anengineering project, and providing a building engineering project management system which is high in data processing efficiency, is convenient for data management, is highly informationized, achievesthe data sharing, achieves the whole-system flow management, and facilitates the monitoring of the government.
