1. Use of ISTforCE Concurrent Engineering Services Platform – a Case Study in Conceptual Structural Design M. Eisfeld & R. J. Scherer Institute of Applied Computer Science in Civil Engineering, TU Dresden, Germany J. Cervenka Cervenka Consulting, Prague, Czech Republic

2. Features of Conceptual Design on Platform Design Assistance System DAS provides design knowledge Designed structure is exchangable via the IFC 2x data model Increased productivity by sharing information across tasks Rentable remote task-specific services from the platform Plug-in functionality on demand from Internet Time and space resources for simulations not needed on local machines

3. User-Tool-Interaction on Platform ISTforCE platform Local engineering applications Personal platform Project infrastructure services for data integration Remote engineering services PDSMAS/S VTLS 3rd party service DAS ? Service Launcher Structural Engineer MAS/C ? ? Interactive design by DAS Remote simulation via terminal server Exchange of model data via MAS browser

4. Tool-Service-Interaction on Platform ISTforCE platform Local engineering applications Personal platform Project infrastructure services for data integration Remote engineering services PDSMAS/S VTLS 3rd party service DAS ? Service Launcher Structural Engineer MAS/C ? ? Upload of structural IFC 2x data via MAS client Downlaod of structural IFC 2x data via MAS client Storage and retrieval of product data to product model server by MAS server

5. Local Application DAS Planning Board design of overall structure and its parts Tools define members select alternative types design gross-sections

6. Model Access Server (MAS/S) Remote Appl. Service (VTLS) Local Application (DAS) Sythesis of structural scheme by DAS Validation of behavior by VTLS IFC 2x product data MAS/S Extended Workspace on Platform
