36. BIM Ontology

The BIM ontology is an informal, semi-structured, conceptual ‘domain ontology’ used for knowledge acquisition and communication between people. It is intended to represent knowledge interactions (push/pull) between BIM players, their deliverables and requirements, and facilitate the validation of conceptual models.

33. Difference between Lenses and Filters

Lenses and Filters are investigative tools of enquiry and domain analysis allowing the discovery of concepts and relations. The difference between (BIM) Lenses and Filters can be summarised as such: Lenses are additive and are deployed from the ‘investigator’s side’ of BIM Field observation while Filters are subtractive and are deployed from the ‘data side’. Lenses highlight observables that meet …

32. Relevance Metric

22. Collaborative Education Framework

The collaborative education framework (CEF) has been developed as a joint effort between academia and industry in Australia. CEF was first published as part of the AIA/CA BIM in Practice, BIM Education position papers (AIA/CA, 2012) and is built around the principles, models, taxonomies, and classifications of the BIM Framework. CEF includes six main complementary components.

1. The Tri-Axial Framework

This conceptual model explains the multi-dimensional relationship between the three main components of the BIM framework: BIM fields of activity identifying domain players, their requirements and deliverables; BIM stages delineating minimum capability benchmarks; and BIM lenses providing the depth and breadth of enquiry necessary to identify, assess and qualify BIM fields and BIM stages.
