5. 30.04.2015 5 IFC  Industry Foundation Classes  From DRAWING to MODEL  Not lines and surfaces, but building OBJECTS  Way of exchanging building information IFC Architect Authority Builder Owner Model server

7. 30.04.2015 7 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

8. 30.04.2015 8 Information Exchange in the Building Process Information- model centrerd Document centered Check out/check in data File exchange: Data is not exchanged, drawings are (e)mailed. Model exchange: Data is exchanged on application specific formats and drawings are (e)mailed. Model server: Data is exchanged using a neutral format. Data is available in a neutral model server and is accessed from different applications. Drawing Model Legend: Document Model file Standardized model data Data centrerd (Thanks to Lars C. Christensen, Selvaag Blue Think)

9. 30.04.2015 9 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

11. 30.04.2015 11 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)

12. 30.04.2015 12 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. 30.04.2015 13 BARBi Example II:  Door:  In Norway: –“Høyde” (height) –“Bredde” (width) –“Brannklasse” (fire category)  In United Kingdom: –“Height” –“Width” –“Fire Category” –“Security Class” DFI7362LHAS00CC E34FJ55693HD340 A3R33693U88CC3 8944GGQQL9883C

15. 30.04.2015 15 BARBi and China  Letter of Intention signed between Chinese authorities and Norway  June 2004  Provide a Chinese IFD platform  Support in establishing IFD data

16. 30.04.2015 16 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 Here!
