Definition of a Building Information Modelg
National BIM Standard Definition of BIM
f ( ) fA Building Information Model (BIM) is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from i i dinception onward.
A basic premise of BIM is collaboration by different stakeholders at different phases of the life cycle of a facility tostakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM process to support and reflect the roles of that stakeholder. The BIM is a shared digital representation founded on open standards for interoperability.interoperability.

Consensus about What?Consensus about What?
• NBIMS Consensus is about draft standardsNBIMS Consensus is about draft standards between development phases, and consensus about standard specifications once through the development phases.
• Standard development phases include: programming, design, construction, and deployment
NBIM Standard Development Process• Programming Phase – Capture user knowledge
through use of the IDM process
• Design Phase – Generic software concepts are• Design Phase – Generic software concepts are developed to represent data for exchange requirements
• Construction Phase ‐ Generic MVD from the Design• Construction Phase ‐ Generic MVD from the Design Phase are developed into technology specific MVDs and implemented into pilot software products
• Deployment Phase – End‐user adoption of NBIMDeployment Phase End‐user adoption of NBIM Standard concepts and products in project agreements, generic and application‐specific BIM guides, certified software, validation of the g , ,construction and contents of a BIM, and using model exchange files
• Approval methods in the Consensus Process apply to all phases of the NBIMS Development and Use Process
Standard of StandardsStandard of Standards
• The National BIM Standard is a standard of standards
• NBIMS is an exchange standard – Specification for exchange requirements in addition to
a methodology for exchange
• Specification candidates are developed by external organizationsg– Presented to the National BIM Standard for review,
discussion, and balloting

• Includes issuance of Standard specifications• Includes issuance of Standard specifications
• Includes consensus voting, which is believed to be g,essential in order to achieve an open and transparent, inclusive, and representative standard
Consensus Process DevelopmentConsensus Process Development
• The NBIMS Consensus Task Team is scheduled to submit a draft of the Consensus Process to the Executive Committee by August, 2008.
• Working to ensure preliminary consensus process diagram reflects all stakeholders, products, and thediagram reflects all stakeholders, products, and the process
• Emphasis on the National BIM Standard as community driven
NBIM Standard Consensus Process• Items currently under consideration:
– Policy and methodology for establishing and maintaining Committee Members eligible to vote on ballot itemsCommittee Members eligible to vote on ballot items
– A definition of the process for the intake of candidate specifications
– Defining a process for evaluation of offered candidatesDefining a process for evaluation of offered candidates against NBIMS criteria
– Establishing procedures for the assignment of candidates to subcommittees for review, development and
d ti t ti brecommendation to voting members– Definition of the rules, requirements, and procedures for
promoting a candidate through draft, review, and balloting stagesstages
– Establishing a methodology and mechanism for publishing candidate specifications, discussions, revisions, approved ballot items, balloting results, etc. , g ,
