1 IFC/IFD Opportunities and Challenges Håvard Bell, Ph.D. Norwegian Building Research Institute




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 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 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 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 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 IFD International Framework for Dictionaries ISO (DIS) 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 Norsk! ?? English! IFD (BARBi) Communication Method? IFC Speaking

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 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 DDS Demo

14 BARBi Bygg og Anlegg Referanse Bibliotek Norwegian implementation of IFD Complete and working implementation of IFD 999 activities/processes, 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 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 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 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 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




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

24 NBIs 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

25 NBIs Knowledge Base Highly used… …and not used

26 Application NBIs Knowledge Base NBIs Knowledge Base

27 Three Ingredients NBIs Knowledge Base (IFC/IFD) BARBi (IFD) Model Server (IFC) NBI Service

28 Hva kan DU gjøre? PRODUKT MALER

29 Questions?

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

31 NBI Service Lifetime of Building?

32 What material? NBI Service IFC Model

33 Its 32DFE854KE NBI Service IFC Model

34 What is 32DFE854KE? NBI Service BARBi

35 Its Aluminum NBI Service BARBi

36 OR…

37 I dont know NBI Service BARBi ?

38 NBI Service What is 32DFE854KE?

39 NBI Service Its Aluminum

40 What is definition of Aluminum? NBI Service BARBi

41 Its Aluminum NBI Service BARBi

42 DFE854KE is Aluminum NBI Service IFC Model

43 What is Lifetime of Aluminum? NBI Service NBI Knowledge Base

44 Years NBI Service NBI Knowledge Base

45 Aluminum at your place lives 40 Years NBI Service IFC Model

46 NBI Service 40 Years

47 NBI Service Thanks!

48 IFC Model BARBi NBI Knowledge Base NBI Service Lifetime of building? What material? Well defined material? Get lifetime data for models area 40 years Overview
