effect of ifc
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

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

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.

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

barbi
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)
barbi example i
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

BARBi Example II:
  • Door:
    • In Norway:
      • “Høyde” (height)
      • “Bredde” (width)
      • “Brannklasse” (fire category)
    • In United Kingdom:
      • “Height”
      • “Width”
      • “Fire Category”
      • “Security Class”

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

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
