A controlled Integral Product Model (IPM) in Building and Construction

Abstract: Significant improvements within Building and Construction projects are expected from the application of the Building Information Model, BIM. A major cause of failure costs is the use of invalid or wrong documents / models in the process. This means when BIM is the central data source in the project it should be up to date at any moment in time.Today the BIM model is often one huge single file, usually a merger of two or more files created by different disciplines, for example the model of the architect and the model of HVAC project partner. A BIM file is very often released as one object which indicates a bad controlled process because the Building Information Model is a collection of many objects each having its own life cycle. The use of the building information model BIM is still restricted to a few areas. A major application of the BIM model today is the use of its geometry model. This is used as a verification tool, e.g. interference checking. The Integrated Product Model (IPMŪ) concept places a well managed digital product model in the centre of the design and engineering process in which all engineers at different disciplines and locations are working together. Well managed means that there are appropriate release and change processes in place. The paper discusses an integrated design and engineering environment using the IPM-concept and applying modern configuration management concepts to assure actual and good documents or models all the time. An example is given how Product Lifecycle Management (PLM) systems are used to deliver good document / models to the BIM model. The paper concludes that BIM should be more integrated in the design and engineering process and eventually needs to be integrated in a PLM environment.
