Research On All-life-cycle Information Management Of Construction Project

The problem of all-life-cycle information sharing in construction project is always a key work of the research on construction informationalization. The construction process of the project commonly holds a long period with large numbers of information formed. Asymmetry and missing of information inevitably occurs among the project participators, which lead to low efficiency and veracity. The informationalization management of construction project has the superiority to share the information resource and improve the efficiency of project. It is beneficial to a single project or the enterprise even the whole society.Firstly the outer relationship system and the information flow of project are analyzed in the paper. And the information classification coding and collection methods are discussed subsequently. In the main part of the paper, researches on different stages information of project are carried on, which include the contents of describing the project workflow, analyzing the information demands of different project participators, discussing the specific information flow of construction stages, and using project information to achieve the project object management.The emphases on this paper are put on the analyses of actual engineering practice. The finally purpose of the research is to found an information management system with Information Technology and ultimately constitute an integrated management system with network.
