Development And Practical Applications Of Enterprise Project Management Information System For Chinese Large And Medium-sized General Contractors

Informatization of Chinese general contractors has been hampered by the fact that enterprise project management information systems is lagging behind. Through field surveys, expert interviews and literature analysis, the dissertation gives a systematic study and practical application on enterprise project management information systems for Chinese general contractors, based on the experience of China Academy of Building Research(CABR) from developing dozens of enterprise project management information systems for Chinese large and medium-sized general contractors.Following studies are conducted in the paper: the writer gives analysis about the status, problems and difficulties faced by informatization of Chinese general contractors on construction project management, and argues three issues urged to be solved; the dissertation conducts a thorough study on the focused issues of conceptual framework, business model and information-based model, software development and application about enterprise project management information systems.The main contributions can be summarized as follows.1) A conceptual framework about enterprise project management information systems for Chinese large and medium-sized general contractors is given in the dissertation, including two parts: a) a practical framework how to develop a construction project management information system; b) a framework of general contractor's project management information system, in which cost management subsystem and contract management subsystem are core and backbone.2) Business model and information model for reference of enterprise construction project management information system are established, which including operating and tendering management, contract management, subcontractor management, material management and cost management.3) A cost estimation and planning subsystem solution is given, which can be applied in variances of practice condition including deferent Enterprise Standard Cost, deferent cost estimation result integration way and deferent cost planning method. And practical innovative applications in general contractors from deferent areas and deferent construction industries are shown.4) Meeting deferent demands from variances cost accounting mode of deferent projects in Chinese large and medium-sized general contractors, a cost accounting subsystem solution is also investigated, which is integrated with the business management subsystems of enterprise project management information system.
