3.0 Object Classification

This section of the standard sets out the requirements for classifying the object and assigning it the
correct IFC designation.

  3.1 Object IFC designation
This sub-section of the standard defines the requirements for the designation of the object in IFC to aid interoperability of the BIM object between different BIM applications. See Appendix A for the available IfcElementTypes and PredefinedTypes from the IFC4 schema.
 3.1.1 IFC type
  The BIM object shall be designated the appropriate IfcElementType and PredefinedType, see clause 4.3.2.
   
  3.2 Object classification
This sub-section of the standard defines the requirements for the classification of the BIM object. Due to the proliferation of systems in use, it is likely that an object may need to support multiple classifications (addressed in Section 4 of this standard).
   
 3.2.1 Classification system
  The object should be classified using a system(s) that reflects those of the jurisdiction where the object is intended for use.
The classification code should be as specific to the object type as possible, see clause 4.6.1.
   
 3.2.2 Hard-coded classification
  BIM objects can be classified using the BIM authoring system’s hard-coded assembly code (or costing code) and keynote code
