  1. ICT Platform for Object Oriented Knowledge Håvard Bell, Ph.D. Norwegian Building Research Institute

  2. IFC IFD IFG

  3. Authority Builder Architect IFC Owner Model server IFC • Industry Foundation Classes • From DRAWING to MODEL • Not lines and surfaces, but building OBJECTS • Way of exchanging building information

  4. IFC + IFD produkt modell Laws and Regulations -Building rules -Building regulations CAD software -Drawings, calculations -Architect, engineer,… VRML -Visualization, 3D models Knowledgebase -Predefined solutions -Design sheets -In house knowledge bases Simulations -Comfort -HVAC -LCC -Light & sound -Insulation -Fire -Environment -Lifetime-analysis Building design -Functional spec. -Estimates -Budget -Specs Remodeling, refurbishing -Remodeling -Demolition -Refurbishing FDVU -Rental, sale -Maintenance -Warranties Building specifications -NS 3420 (bill of quantity) -NS 3451 -Calculations, estimates Progress and schedules -Scheduling -Logistics, 4D Product ordering -Product databases -Price databases Images from: Byggforsk, Olof Granlund, NBLN University of California, Stanford University

  5. Effect of IFC? • “Low friction information logistics” • Lars C. Christensen, Selvaag Blue Think • New decision processes: • Earlier access to information • Possible to simulate decisions and see the consequences earlier

  6. Legend: Model Drawing Document Check out/check in data Information Exchange in the Building Process (Thanks to Lars C. Christensen, Selvaag Blue Think) Document centered File exchange: Data is not exchanged, drawings are (e)mailed. Model exchange: Data is exchanged on application specific formats and drawings are (e)mailed. Data centrerd Model file Model server: Data is exchanged using a neutral format. Data is available in a neutral model server and is accessed from different applications. Information-model centrerd Standardized model data

  7. IFD • International Framework for Dictionaries • ISO (DIS) 12006-3 • Needed to define concepts and relations • Are we talking about the same thing? • The semantics of IFC • Adoptable on national or project levels • A “column” might be defined as an IfcColumn plus some customized attributes, or even attached objects

  8. Norsk! 日本語！ English! ? ? IFD (BARBi) Communication Method? IFC Speaking

  9. BARBi • Bygg og Anlegg Referanse Bibliotek • Norwegian implementation of IFD • Complete and working implementation of IFD • 999 activities/processes, 40901 names, 6600 definitions, 1939 properties, 8757 objects/subjects, ca 1300 relations, etc.. • Based on EXPRESS (EDM, EPM Tech.) • Will provide a free reference library to the Norwegian Building Industry • Anyone can access and use it • Import functions from LexiCon • (Netherlands's IFD implementation)

  10. BARBi Example I: • A concept may consist of: • Global unique ID • Names (may be several) • Definition • Unit(s) • Value(s) • Etc. • Products are defined through properties • A set of properties (concepts) and perhaps values, defines a product

  13. BARBi and China • Letter of Intention signed between Chinese authorities and Norway • June 2004 • Provide a Chinese IFD platform • Support in establishing IFD data

  14. Here! IFG • IFC enhancement for the GIS world • Close to completion • Allows the 2D map world to talk to the 3D building world and vice versa • You know where the building is in the world

  15. Today IFG IFG Aim: (Thanks to Jøns Sjøgren, Home Builders Association) 3D? Yes, but what is it? 3D 3D? Yes, here it is! Kilde: Statens Kartverk

  16. NBI’s Knowledge Base • Over 800 design sheets • Best practice • Research • Etc. • Over 50 years of experience • Highly regarded in the industry • Example: • How to properly lay a bathroom floor

  17. NBI’s Knowledge Base • Highly used… • …and not used

  18. NBI’s Knowledge Base NBI’s Knowledge Base Application Application

  19. Three Ingredients Model Server (IFC) NBI’s Knowledge Base (IFC/IFD) NBI Service BARBi (IFD)

  20. Lifetime Analysis • Factor Method • Empirical data collections • Theoretical Formulas • Statistical Analysis • Developed over time • (Not my area of expertise…)
