BIM Interactions are push-pull knowledge transactions occurring within or between BIM Fields and sub-Fields. Push mechanisms transfer knowledge to another field or sub-field while pull mechanisms transfer knowledge to satisfy a request by another field or sub-field. Sample transactions include data transfers, team dynamics and contractual relationships between fields and sub-fields.

BIM Lenses represent the third dimension of the Tri-Axial Model and generate its depth of enquiry. BIM Lenses are distinctive layers of analysis applied to Fields and Stages to generate Knowledge Views. They abstract the BIM domain and control its complexity by removing unnecessary detail. Lenses allow domain researchers to selectively focus on any aspect of the DCO industry and generate knowledge views that either (a) highlight observables which meet the research criteria or (b) filter out those that do not.

Below is a short video briefly explaining the above on the dedicated BIM Framework YouTube channel:

The BIM Framework introduces the stages separating Pre-BIM (the status before BIM) from viDCO (virtually integrated Design, Construction and Operation) - the ultimate vision from implementing BIM. These revolutionary stages, and the evolutionary steps separating them, are intended to both clarify and measure BIM adoption.

Note 1: this model depicts BIM Capability Stages at Maturity Level C...Also, starting in Paper A4, the term viDCO replaces the term IPD as used earlier in Papers A2 and A3

Note 2: The ‘BIM Stages’ model was first introduced by the author through BIM ThinkSpace (Episode 8 – Feb 18, 2008) and then published in Paper A2 as ‘BIM Maturity Stages’. As of Paper A3, the BIM capability/maturity concept embedded in the original model was split into two metrics/models: BIM Capability Stages and BIM Maturity Levels.

Update (July, 2015) - below is a short video explaining the above on the Framework's YouTube channel:

This conceptual model represents BIM Fields, the first dimension of the Tri-axial Model. BIM Fields refer to all topics, activities, and actors across the BIM domain. The Venn diagram (three overlapping circles) identifies Field Types (Technology, Process and Policy), Field Components (Players, Deliverables and Requirements), Field interactions and Field overlaps.

The model was first referred to as ‘three interlocking knowledge nodes’ in Paper A1 "A Proposed Framework". The term ‘nodes’ was later replaced with ‘fields’ to match the notion of ‘players’.
