23 MVDs

The National Building Information Modeling Standard will be comprised of different parts.  Works in progress to standardize certain ways of looking at things in the AEC/FM Architecture Engineering Construction Facility Management Industry are Model View Definitions using IFC Industry Foundation Classes and IFC based solutions for data exchange. Currently there are 23 MVD‘s in progress. MVD’s with diagrams are below.

Some MVDs are at the design stage, some have diagrams shown below. Generic concepts are on the left side in blue, IFC 2×3 Binding Concepts are on the right side in yellow.

Architectural Design > Structural Design

The General Concepts include: Beam, Building, Building Storey, Column, Grid, Project, Ramp, Site, Slab, Stair, User Defined Object, and Wall. The IFC 2×3 Binding Concepts include: Beam, Building Element Proxy, Column, Project, Ramp, Site, Slab, Stair, and Wall. Apparently the Building Element Proxies encompass User Defined Objects and the Building Stories.

Architectural Design > Thermal Simulation

Will be useful for energy performance and sustainability studies. Here the main concept on both sides is “Space”

BPEA Building Performance Energy Analysis 

More detailed for sustainable studies, now project is moved above, spatial components are separated from other concepts, the building elements are more defined.  Spatial zones are indicated which can be related to sensor data and long term performance tracking.

Code Compliance Checking

Focuses on the building systems and elements. Codes vary by jurisdiction boundaries, can’t these geometric boundaries be used to help narrow down relevant codes?

Concept Design > Quantity Take Off

Costs. Organized by Project first, then Site, Building, Building Storey, and Space.

Indoor Climate Simulation > HVAC Design

Related to Code Compliance Checking.  Project is not separate here, the main generic categories are Building, Building Storey, Project is at this level, Site, Space, and Thermal Zone. Long term wide spread studies might combine this MVD with sustainable processes listed above.

Spatial Requirements and Target > Thermal Simulation

Focusing here on Project and Space Type

Structural Design > Structural Analysis

Looking at: Building, Building Storey, Project, Structural Analysis Curve Connection, Structural Analysis Curve Member, Structural Analysis Point Connection, Structural Analysis Surface Member, Structural Linear Action, and Structural Point Action. Reminds me of the art fundamentals program at Virginia Commonwealth University where students explore surfaces and spaces. Mathematicians analyze critical points and actions too, how can there be an internship program bringing together people in their 2os across each discipline?

What’s needed next is a map of open standards in NBIMS MVD formats.
