CONCUR Demonstration Scenario Description The demonstration scenario covers the activities in the process of moving from a client brief to preparing a bid for the building to house the steam powered turbine/generator for a small power station. The demonstration mostly uses commercially available software applications and generally uses IAI IFCs for transferring and storing building and construction objects between partners and their software. Fortum Engineering perform the role of the principal contractor who undertakes the plant design with alternative solutions from civil engineering contractors. The demonstration scenario includes: Inception Design Concept Design Scheme Design Programme Planning Preparing Cost Plans The innovations include: Using IAI-IFCs for exchanging information Using IAI-IFCs for storing information Using a web based IMS which includes an IFC model server Using a web based browser for viewing and using IFC objects Using an XML interface for interfacing with IFC models This presentation shows the business activities being addressed, the information flows between the activities and further information on the activities which can be accessed by clicking on the activity boxes or information flow lines.
