There’s Still Time to Submit; Ballot Period Ends August 19

The ballot submission period to update the nation’s building information modeling (BIM) standard is nearing its end. There are only two weeks left to submit proposed revisions and standards for inclusion in the National BIM Standard – United States™ (NBIMS-US™).

For nearly two months, building professionals from across the nation and around the world have had the opportunity to offer their ideas to improve the NBIMS-US™ as the National Institute of Building Sciences buildingSMART alliance™ begins the process of developing NBIMS-US™ Version 3.

The NBIMS-US™ Project Committee has since received a number of completed ballot submissions and been notified of ballots that are due in before the deadline of August 19. Here is a sampling of what has been submitted or is currently in the pipeline:

Submitted Ballots:

  • LCie – This ballot for the Lifecycle information exchange (LCie) streamlines the process of collecting lifecycle information on facility assets.
  • BAMie – This ballot for the Building Automation Modeling information exchange (BAMie) includes the data for preparing an open standard exchange format to simplify the collection of information across all types of building control systems.
  • COBie – This ballot for the Construction Operations Building information exchange (COBie) updates the current content in the NBIMS-US™ to include the latest version of COBie, Version 2.4, which has been implemented and tested in programming, design, construction, commission and computer-aided facility management (CAFM)/computerized maintenance management system (CMMS) tools.
  • HVACie – This ballot for the Heating, Ventilation and Air Conditioning information exchange (HVACie) captures information about the assemblies and connections that comprise the HVAC system within a facility.
  • SPARKie – This ballot for the Electrical System information exchange (SPARKie) delivers information about the electrical components, plus the distribution panels, feeders and circuits that allow the system to function.
  • WSie – This ballot for the Water System information exchange (WSie) addresses the piping, valves and strainers that comprise the water system of a building.

In the Pipeline:

  • Level of Development – This ballot provides a model progression description for the American Institute of Architects (AIA)/E203 Level of Development, which can be used as part of the AIA contract document or guide documents. It sets expectations on the level of digital data and BIM to be used in a project.
  • OmniClass™ –This ballot proposes eight new OmniClass™ Tables for inclusion in the current edition of NBIMS-US™. OmniClass™ is a classification system for the construction industry.
  • USACE M3 Model Element Table – This ballot for the Minimum Modeling Matrix (M3), developed by the U.S. Army Corps of Engineers, establishes the minimum content requirements to include for facility model elements in military construction projects.
  • NBIMS-US™ Terms and Definitions – This submission ballots the definitions of terms used in Version 1 and Version 2, and proposes new Version 3 industry definitions.
  • NCS – This ballot submits the United States National CAD Standard® (NCS) as a referenced standard. The NCS is the standard that normalizes computer-aided design drafting.

Since NBIMS Version 1- Part 1 was first released in 2007, the content of the standard has evolved. The current edition, NBIMS-US™ Version 2, is a consensus-based standard that includes reference standards, information exchange standards (which are built upon the reference standards) and best practice guidelines to support users in their implementation of non-proprietary BIM standards-based deliverables.

Not only is NBIMS-US™ Version 2 the BIM standard in use here in the United States, applicable portions of the standard also serve as the basis of a number of other countries’ BIM standards, including South Korea and the United Kingdom. Therefore, the submitted ballots, if approved by the Project Committee, could potentially impact millions of people in facilities being built around the world.

The Ballot Submission Period for NBIMS-US™ Version 3 ends August 19, 2013. View the Schedule. Only National Institute of Building Sciences buildingSMART alliance™ NBIMS-US™ Project Committee members can submit and vote on ballots. Committee members, download ballots now.
