IFC, what is IAI about? Vision –To enable software interoperability in the AEC/FM industry. Mission –To provide a universal basis for process improvement and information sharing in the construction and facilities management industries. Deliverables –The key deliverable of the IAI is the IFC Object Model. The term ‘model’ in this case means that it provides a formal specification of requirements which can then be used by software authors to create the IFC compliant software applications.

IFC, Exercise/questions? Exercise: –Why are we still producing ordinary documents/drawings in the construction industry? –Is it possible to create, maintain and implement a vendor independent product model? –What are the benefits/drawbacks of a generic product model compared to a more specified model? Or should I show something from the model?

Industry Foundation Classes Students are hereby invited to use the IFC specifications in their work, and take part in the development, testing and implemen- tation of IFC. Thanks for listening ! Iaiweb.lbl.gov
