4 07.06.2014 4 IFD IFC IFG

5 07.06.2014 5 IFC Industry Foundation Classes From DRAWING to MODEL Not just lines and surfaces, but building OBJECTS Way of exchanging building information IFC Architect Authority Builder Owner Model server

6 07.06.2014 6 IFC + IFD produkt modell Images from: Byggforsk, Olof Granlund, NBLN University of California, Stanford University Building design -Functional spec. -Estimates -Budget -Specs Knowledgebase -Predefined solutions -Design sheets -In house knowledge bases Laws and Regulations -Building rules -Building regulations CAD software -Drawings, calculations -Architect, engineer,… VRML -Visualization, 3D models Simulations -Comfort -HVAC -LCC -Light & sound -Insulation -Fire -Environment -Lifetime- analysis Building specifications -NS 3420 (bill of quantity) -NS 3451 -Calculations, estimates Product ordering -Product databases -Price databases FDVU -Rental, sale -Maintenance -Warranties Remodeling, refurbishing -Remodeling -Demolition -Refurbishing Progress and schedules -Scheduling -Logistics, 4D

7 07.06.2014 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 07.06.2014 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 07.06.2014 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

10 07.06.2014 10 Norsk! ?? English! IFD (BARBi) Communication Method? IFC Speaking

11 07.06.2014 11 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!

12 07.06.2014 12 IFG Aim: 3D? Yes, but what is it? 3D? Yes, here it is! 3D Kilde: Statens Kartverk Today IFG (Thanks to Jøns Sjøgren, Home Builders Association)

13 07.06.2014 13 DDS Demo

14 07.06.2014 14 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)

15 07.06.2014 15 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

16 07.06.2014 16 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

17 07.06.2014 17 BARBi and China Letter of Intention signed between Chinese authorities and Norway June 2004 Provide a Chinese IFD platform Support in establishing IFD data

18 07.06.2014 18 BARBi Status BARBi in itself is completed BARBi Interface version 0.8 launches 20th of December 2004 You can start input of data WE NEED PRODUCT TEMPLATES Window!!!!! WE NEED THE DATA

21 07.06.2014 21

22 07.06.2014 22 BARBi & NOBB Project recently initiated through BIT-BYGG Product Templates Window! NOBB & BARBi integration Synchronize and harmonize IFC integration Mostly through BARBi integration But some adoption necessary Very good cooperation with ODA/NOBB

23 07.06.2014 23 Service Provider Model Produkt leverandør Produkt leverandør NOBB Norway Produkt leverandør Produkt leverandør Manufacturers Country b Service Provider ? $$$$ $$ $$$$$ $$$ Owner
