The alliance said the National BIM Standard-United States™ (NBIMS-US™) Version 2 (V2) covers the full life cycle of buildings — from planning, design, and construction to operations and sustainment. Part of an international effort, the NBIMS-US™ V2 will serve as the kick-off point for a number of other countries around the world to adopt as their own BIM standard.
“This is a major step forward in the industry,” said Dana K. “Deke” Smith, FAIA, buildingSMART alliance executive director. “The involvement of all sectors of the facilities industry will play an important role in how effective NBIMS will be in the long term, both in the United States and abroad. We look forward to everyone providing content for future versions.”
The previous edition — United States National Building Information Modeling Standard™ (NBIMS) Version 1 - Part 1 (V1P1): Overview, Principles and Methodologies — came out in December 2007. NBIMS V1P1 primarily established the approach for developing open BIM standards. Written by a team of 30 subject matter experts, the NBIMS V1P1 followed an open process but it was not a consensus standard.
The newly released NBIMS-US V2 follows an open consensus process set by rules of governance established by NIBS. During the development process, anyone was able to submit ballots to the standard and all members of the NBIMS-US Project Committee (which is open to any member of NIBS in good standing) were able to provide comments and vote on ballots.
The approved ballots fell into three main categories: reference standards, information exchange standards (which are built upon the reference standards), and best practice guidelines that support users in their implementation of open BIM standards-based deliverables.
The alliance, which is both a council of NIBS and the North American chapter of buildingSMART® International, is working with several other nations on BIM standard development. The United Kingdom, Ireland, Canada, Korea, Australia, and New Zealand are all planning to take NBIMS-US V2 as the basis for their own standards. Each nation will add more content as needed and then share their updates with the United States. International discussions include translating NBIMS-US V2 into French, converting the U.S. measurements into metric, and adding a template to contain BIM in boiler plate contract language.
