#28 - BIM Model Types

Discipline and Design Intent Models

• Planning Model: this is a simple model used for preliminary studies, early project planning, and programming. Space and area tools are used to define programming needs, space calculations, schematic massing, blocking and stacking, massing for site location, and early energy analysis to rapidly explore multiple options. These models can be used as a basis for design development.

• Work in Progress (WIP): are specific discipline model. Examples are architecture, structure, and MEP. These models are combined or federated for design development, and BIM Use execution. These models are used during project progress reviews. The reviewed and approved WIP models are federated into the Design Intent Model.

• Design Intent Model: supports design execution, decision support, clash avoidance, and final construction documentation. The Desing Intent Model is a contract deliverable for submission. The Design Intent Model contents are updated to reflect as-built conditions to become the Record Model.

• Construction Coordination Model: is the further development of the Design Intent Model by the team. The shop/trade models are developed by the sub-contractors. Smaller digital mock-ups may be created by the construction team to detail specific elements, the intersection of building conditions, or systems for constructability review.

• Record Model: this is a contractual requirement and is the basis of the facility management model. It is the Design Intent Model updated to show as-built locations. It does not have the same level of construction detail as the As-Built model. It may be used by commissioning. Equipment data and other information is updated in this model.

• As-Built Model: file is a contract requirement. It includes shop models and drawing information from trades and fabricators with the as-installed conditions. This file may also include point cloud data.

• Parametric Models: provides additional capability to BIM authoring tools. Parametric Modeling moves BIM one step closer to simulation. This is useful during design option development.

• Digital Mock-Ups: are sub-models of design details to study design and constructability issues. These are used in studies, design development, and construction coordination.
