Due to the lack of effective coordination between stages of the construction process, the importance of integrating information modelling techniques with the view to creating a generic integrated product and process model that is applicable to all stages of a construction project's life cycle, is being recognised by the architecture, engineering and construction (AEC) industries and the computer integrated construction (CIC) research community. However, improved methods are still needed to assist the developer in the definition of information model structures. Current available modelling methods and standards can only help at certain stages of the information modelling process. This paper proposes a prototype of a generic Hyper-Integrated Product and Process modelling information system (HIPPY). The main functions of the prototype include integrating information models with document files using data transferring techniques and multiple software applications. Functions, software architecture, implementation and exploitation of the integrated modelling framework are presented. The paper first reviews existing modelling efforts addressing integration in the AEC domain. It explores the advantages of combining modelling methodologies in the definition of the structure for integrating data that will support computer applications through the project life cycle. The approach adopted in this paper uses unified modelling language (UML), IDEF0 and scheduling charts (project planning). The combined use of these methods means that the weaknesses of each could be counteracted by the strengths of others. Finally, the user-interface through which project participants interact with multiple applications in the integrated environment is presented.
