Building Information Model DefinitionBuilding Information Model Definition
National BIM Standard Definition of BIM – buildingSMARTA Building Information Model (BIM) is a digitalrepresentation of physical and functionalcharacteristics of a facility. As such it serves as ashared knowledge resource for information about afacility forming a reliable basis for decisions during itslife-cycle from inception onward.
A basic premise of BIM is collaboration by different stakeholders atdifferent phases of the life cycle of a facility to insert, extract, update ormodify information in the BIM process to support and reflect the roles ofthat stakeholder. The BIM is a shared digital representation founded onopen standards for interoperability.
The National BIM Standard is part of the global buildingSMARTInformation Delivery Manual Initiative.
1. Define expansive scope of BIM– Everyone starting from different points of view– Breaking down stovepipes– Developing awareness and appreciation of life-cycle
approach2. Define first and subsequent versions of the
Standard– Can’t boil the ocean– Need to know when and what information will be
available– Need to identify authoritative sources and ensure

Planned Products For Each Exchange StandardPlanned Products For Each Exchange Standard
• The NBIM Standard is a collection of standards published ashuman-readable documents containing guidance for usersand for application developers:
• A non-technical description of the standard & its intendeduse.
• A diagram illustrating the process the standard addresses.• A technical description for application developers to use.• Contract language for incorporating the exchange
requirement into building process agreements.• Results of test-bed activities including participants, results
and any issues.• Instructions & other change management materials.• Statements as to the maturity of the Standard and any plans
SYSTEMS –Ex. Structural, MEP, Flooring, Ceiling, Exterior, Walls
SPACE-Vertical Horizontal, Empty
OVERLAYS – Typically associated with building hierarchy elements.

Systems represent the physicalentities of the building. Systems useNA classifications such as Omni-Class and Uniformat and aretransported/exchanged via IFCs
Space is physical in nature, but canbe unbounded (have no or crossphysical boundaries) but it will alwaysbe tied to the physical structure orsystems in some wayOverlays are more abstract data -organizational, operational, functional,financial, non-fixed assets, resources,personnel, etc. that is data tied to theSystems and Space
