Mission

The mission of the National BIM Standard-United States Project Committee as identified in the Rules of Governance is to lead the development and deployment of broadly adopted national information standards and best practices for the built environment, with a focus on significantly improving project delivery and operational processes.

NBIMS-US V4 Project Committee (PC)

The NBIMS-US Project Committee (National BIM Standard-United States Project Committee), is a project committee of the Building Information Management (BIM) Council which is a council of NIBS. The NBIMS-US Project Committee brings together the broadest and deepest constituency ever assembled for the purpose of establishing and managing through an Industry consensus process a series of open source National standards and guidance for all aspects of Building Information Modeling. 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.

NBIMS-US V4 Planning Committee (PLC)

The National BIM Standard-United States (NBIMS) Planning Committee (PLC) administers the affairs and consensus process of the NBIMS-US Project Committee (PC) and Workgroups (WG). The goal of the PLC is to create a collection of standards and guidelines that support the implementation of building information modeling and management in planning, design, construction and operations of buildings and infrastructure in the United States and beyond.

A full update of the NBIMS-US will be published every 3 years following a review of the existing published version and annual interim modules. The key feature of this new 3-year cycle and annual module release process is that modules are developed continually as improvements or new content in the form of individual modules are developed. The PLC will accept proposals, identify priorities, stand up workgroups, ballot candidate modules, and publish approved modules as they become available. A public-facing website will display initiatives under development and include workgroup work plans, candidate modules, as well as approved and final modules.

Under a newly-reorganized structure, the NBIMS PLC consists of a chair, vice chair, secretary, as well as 12 BIM Council members, representing core segments of the industry. Every PLC member must be a member-in-good-standing of the NIBS BIM Council and the NBIMS-US Project Committee.

NBIMS-US V4 PLC officers and members:

The PLC created the following Workgroups to lead the development of the new NBIMS modules. A description of the focus of each workgroup is available on the following pages:

BIM USE DEFINITION (BUD) WORKGROUP

Chair: Ralph Kreider
Planning Committee Liaison: Johnny Fortune

The primary focus of this Workgroup (WG) is to identify appropriate BIM Use Definitions and Development Methodology for inclusion in the NBIMS. This includes gathering BIM Uses from existing versions of NBIMS as well as potentially other sources. Each BIM Use should be discussed by the WG and evaluated for any necessary revisions to align with current industry practices. The WG should also engage in sound scholarly research and user interviews or surveys to identify additional BIM Uses that are candidates for inclusion. Additionally, the WG should include a standardized Development Methodology to BIM Uses (such as the approach included NBIMS v3) to provide flexibility of creating custom project-specific BIM Uses that still align with a National Standard. The end state should be one where project stakeholders can pick from a well-developed list of BIM Uses to require them on a project or require a defined process for developing a custom BIM Use. While the BIM Use Definitions are not intended to describe means and methods, all necessary components of the BIM Use should be identified (i.e., prerequisites, input, output, etc.).

Collaboration

This WG is one of several WGs that are focused on topical areas within the NBIMS. All WGs should coordinate any overlapping topics with the leadership of the related WG and the Planning Committee (PLC). Topics outside of the WGs focus area that are discovered during WG activities should be brought to the attention of the PLC for consideration. Additionally, all BIM Uses suggested by other WG must be considered to properly align the various portions of NBIMS. The information contained herein is not intended to be an exhaustive list of responsibilities but rather a starting point.

BIM EXECUTION PLANNING (BEP) WORKGROUP

Chair: Dianne Davis
Planning Committee Liaison: John Messner

The BIM Project Execution Planning Guide (BEP Guide) and corresponding templates included in NBIMS were initially developed in October 2009. The BEP Guide outlines a structured approach for a project team to develop a BEP through a collaborative process leveraging a consistent template for BEP content. In 2012, Version 2.1 of the BEP Guide and Templates were released, and they are incorporated into the NBIMS-US.

While the BEP Guide and Template have been instrumental in driving consistency in the planning process, many large owners and project teams have been improving upon the initial versions of the BEP Guide and Template. There is a need to collect, evaluate, and compile core revisions to the documents that leverage the best content revisions through a structured evaluation.

The goal of this WG is to develop a comprehensive BEP Guide and Templates that can be used as a standard deliverable, with structured extensions or customizations by owners and other project team members if needed.

Collaboration

This WG is one of several WGs that are focused on topical areas within the NBIMS. All WGs should coordinate any overlapping topics with the leadership of the related WG and the Planning Committee (PLC). Topics outside of the WGs focus area that are discovered during WG activities should be brought to the attention of the PLC for consideration. Additionally, the BEP procedure managed within this WG will need to be aligned with other WG content related to BEP within various portions of NBIMS. The information contained herein is not intended to be an exhaustive list of responsibilities but rather a starting point.

CORE BIM REQUIREMENTS (CBR) WORKGROUP

Chair: Connor Christian
Planning Committee Liaison: Carrie Sturts Dossick

The primary focus of this Workgroup (WG) is to define the scope and content for minimum core BIM implementation on a project. This candidate module is intended as a standard to define the minimum requirements for a BIM-enabled project that refers to other comprehensive modules such as Industry Foundation Classes, COBie, BIM Use Definitions, BIM Execution Planning and Modeling Requirements.

Motivation

This module will support industry implementation of BIM through the definition of minimum requirements. The NBIMS content, such as IFC, often focuses on comprehensive definitions without guidelines or requirements as to how to implement these definitions and standards. The Minimum core BIM requirements module would reference these other standards and provide a guide for minimum viable application of these for a BIM-enabled project.

Collaboration

This WG is one of several WGs that are focused on topical areas within the NBIMS. All WGs should coordinate any overlapping topics with the leadership of the related WG and the Planning Committee (PLC). Topics outside of the WGs focus area that are discovered during WG activities should be brought to the attention of the PLC for consideration. As other modules of the standard are revised, this minimum core BIM module must be reviewed for agreement and compliance with referenced modules. The information contained herein is not intended to be an exhaustive list of responsibilities but rather a starting point.

COBIE V3 WORKGROUP

Co-Chairs: Brian Haines & TJ Meehan
Planning Committee Liaison: John Messner

The mission of the NIBS Building Information Management (BIM) Council Construction-to-Operations Building Information Exchange (COBie) Workgroup (CWG) is to exercise stewardship of the Construction‐to‐Operations Information Exchange Model View Definition (MVD) and data schema. The Workgroup fulfills this mission in three ways:

• Ongoing technical development of COBie to meet AECOO industry needs;
• Supporting the process of incorporating successive versions of COBie in the National BIM Standard – United States® (NBIMS-US™);
• Promoting the adoption and implementation of COBie by the building industry

The CWG will develop and maintain an annual operational plan which outlines the activities and specific projects to be pursued within the next year to include quarterly milestones with deliverables along with any resources required to achieve the CWG goals.

BIM INFORMATION STANDARDS (BIS) WORKGROUP

Chair: Aaron Costin
Planning Committee Liaison: Andy Smith

The focus of this Workgroup (WG) is to:

1. Define an information exchange framework to standardize the capture of business requirements, data structure and software implementation for BIM use cases
2. Participate with the other NBIMS-US workgroups to provide guidance for the development of information exchanges
3. Research other industry initiatives for information exchanges to leverage existing capabilities in an effort not to create competing exchanges

Collaboration

This Workgroup is a consultant to all other US-NBIMS Workgroups in that this Group will not initiate the need for an information exchange but will assist with executing the idea. This Workgroup should be an advisor as to the technical possibility and practicality of a successful information exchange.

PRODUCT DATA REQUIREMENTS (PDR) WORKGROUP

Co-Chairs: William Brodt and Yuqing Hu
Planning Committee Liaison: John Messner

The mission of the NIBS Building Information Management (BIM) Council Product Data Requirements Workgroup (WG) is to define the desired product performance and sustainability data elements, the schema for product-specific attributes extending the Construction‐to‐Operations Information Exchange Model View Definition (MVD), and data schema into performance and sustainability data required for product selection, commissioning, maintenance, and operations.

Collaboration

This WG is one of several WGs that are focused on topical areas within the NBIMS. All WGs should coordinate any overlapping topics with the leadership of the related WG and the Planning Committee (PLC). Topics outside of the WGs focus area that is discovered during WG activities should be brought to the attention of the PLC for consideration. Additionally, the BIM product data schema, template, and MVD generated by this WG must be considered to properly align the various portions of NBIMS.
