Model Uses are the “expected or intended project deliverables expected from generating, collaborating-on and linking 3D models to external databases” (BIM Dictionary, 2015). Each Model Use represents a set of defined requirements, specialised activities and specific project outcomes, grouped together under a single heading.
Model Uses  rely on the conceptual structures of the BIM Framework, namely: the Tri-Axial Framework, Competency Framework, and BIM Ontology - Figure 1:
As highlighted in Figure 1, Model Uses are supported by three conceptual structures  - Updated May 2, 2016:
- Within the Tri-Axial Framework, Model Uses are deliverables [Tri-axial Framework>Fields>Field Components>Deliverables (Model-based Deliverables, identified through the Information Management Lens)] (refer to Papers A2 and A5);
- According to the BIM Ontology, a Model Use is a knowledge block [BIM Ontology>Knowledge Objects>Knowledge Sets>Knowledge Blocks> Information Uses > Model Uses] (refer to Thesis, Appendix A); and
- Within the Competency Framework, Model Uses are competency topics [Competency Framework> Competency Hierarchy>Competency Tiers (Domain)>Competency Set (Operation)>Competency Topics (9 Topics)] (Refer to Paper A6).
 The number of structures supporting a BIM Framework part is proportional to its conceptual strength.
