For 50 years, NIBS has been fulfilling its mandated responsibility to the 'development, promulgation, and maintenance of nationally recognized performance criteria, standards, and other technical provisions for maintenance of life, safety, health, and public welfare suitable for adoption by building regulating jurisdictions and agencies.' The standards and guidance below were driven by that directive and produced through industry organization and subject matter expert concensus to promote the advancement of broad-based building interests.

National BIM Standard-United States®

The National BIM Standard-United States® (NBIMS-US™) provides consensus-based standards through referencing existing standards, documenting information exchanges and delivering best business practices for the entire built environment. With open BIM standards, we can build detailed models and deliver accurate products that can be used during commissioning and operation to ensure facility functionality throughout the life of the facility and to deliver high performance, carbon neutral, and net zero energy based facilities.

United States National CAD Standard® (NCS) V6

The NCS is a consensus standard incorporating industry publications. It is comprised of interrelated standards, guidelines and tools for uniformly organizing and presenting facility drawing information. It is the only comprehensive standard for facility planning, design, construction and operation drawings. It coordinates the efforts of the entire industry by classifying electronic building design data consistently allowing streamlined communication among owners and design and construction project teams.

The United States National CAD Standard® (NCS) V6 consists of The American Institute of Architect's CAD Layer Guidelines, Construction Specifications Institute's Uniform Drawing System (Modules 1-8), and National Institute of Building Sciences' BIM Implementation & Plotting Guidelines. 

There are several licensing options and discounts available for NIBS members, government employees, and students. 

The National BIM Guide for Owners

This guide provides building owners with an approach, from their own profession’s standpoint, to create and fulfill building information modeling (BIM) requirements for a typical project. It addresses three broad areas the owner should understand in order to work effectively with the Project BIM Team: process; infrastructure and standards; and execution. The guide provides building owners with a documented process and procedure for their design teams to follow to produce a standard set of BIM documents during the design and construction of the facility, and for maintenance and operations of the facility upon handoff. It is geared to a generic facility with uniform requirements for use by a variety of government, institutional and commercial building owners. It references a range of documents and practices, including those contained within the National BIM Standard-United States®. [January 2017 / 36 pages]
