FAR 11.201—Identification and availability of specifications.
Plain-English Summary
FAR 11.201 explains how specifications, standards, and other requirements documents must be identified, provided, and referenced in solicitations. It covers documents listed in the GSA Index of Federal Specifications, Standards and Commercial Item Descriptions and in other agency indexes, as well as documents not listed there, and it tells contracting offices when they must furnish copies or instructions for obtaining them. The section also addresses how to handle cross-references inside requirements documents so that references are limited to what actually applies, do not conflict with the solicitation, and identify all first-tier references. In addition, it points users to where federal and defense documents can be accessed, including ASSIST, the Defense Standardization Program Office, NIST/FIPS sources, GPO, NTIS, and sources for nongovernment standards. In practice, this section is about making sure offerors can find the exact controlling documents they need to prepare responsive offers and that solicitations do not rely on vague or outdated references.
Key Rules
Identify exact document versions
When a solicitation cites a requirements document from the GSA Index, ASSIST, or another agency index, it must identify the approval date and any applicable amendments and revisions. The solicitation may not use vague language like "the issue in effect on the date of the solicitation."
Do not routinely attach cited documents
Contracting offices normally do not furnish cited indexed documents with the solicitation. They must do so only when the document is needed for a competent evaluation, when it would be impracticable for offerors to obtain it in time, or when a prospective contractor requests a copy of a Government-promulgated requirements document.
Clearly identify unlisted documents
If a pertinent document is not listed in the GSA Index or ASSIST, the solicitation must clearly identify it. The contracting office must either furnish the document with the solicitation or provide specific instructions for obtaining or examining it.
Control document references
When one document refers to another, the reference must be limited to the portions that actually apply to the acquisition, state the extent of applicability, avoid conflicts with other solicitation provisions, and identify all applicable first-tier references.
Use ASSIST and other official sources
The section directs users to ASSIST for the GSA Index and most unclassified Defense specifications and standards, and it provides methods for obtaining Defense documents not available there. It also identifies sources for FIPS publications through NIST, GPO, and NTIS.
Obtain nongovernment standards properly
Agencies may purchase some nongovernment standards, including voluntary consensus standards, through NTIS Fedworld, from the standards developing organization, or from an authorized reseller. NIST can help identify sources and content, and DoD activities may obtain adopted nongovernment standards from the Defense Standardization Program Office.
Responsibilities
Contracting Officer
Must identify cited requirements documents by approval date and applicable amendments/revisions, avoid vague issue references, decide when documents must be furnished with the solicitation, clearly identify unlisted documents, and ensure cross-references are limited, accurate, and nonconflicting.
Contracting Office
Must provide cited documents when required by the rule, give specific instructions for obtaining or examining unlisted documents, and ensure solicitation packages give offerors a fair opportunity to access the controlling requirements.
Prospective Contractor
May request a copy of a Government-promulgated requirements document and is responsible for obtaining cited documents when they are not furnished with the solicitation and no exception applies.
Agency
Must maintain or use appropriate indexes for requirements documents, ensure access to official sources for specifications and standards, and support acquisition personnel in locating federal, defense, and nongovernment standards.
NIST
May assist agencies in identifying sources for and content of nongovernment standards.
Defense Standardization Program Office
Provides access to certain Defense documents not available on ASSIST and may supply nongovernment standards adopted for defense use.
Practical Implications
Offerors need the exact version of every controlling document, so solicitation writers should never rely on generic phrases like "current edition" or "issue in effect."
If a document is hard to obtain or essential to understanding the requirement, the contracting office should include it or give precise retrieval instructions; otherwise, protests or misunderstandings can result.
Cross-references can create hidden requirements, so acquisition personnel should check that every referenced document actually applies and does not conflict with the solicitation.
Using ASSIST, NIST, GPO, NTIS, and standards organizations helps ensure the government and contractors are working from authoritative sources rather than unofficial copies.
A common pitfall is failing to identify first-tier references, which can leave offerors unsure which subordinate documents are mandatory and which are merely background material.
Official Regulatory Text
(a) Solicitations citing requirements documents listed in the General Services Administration (GSA) Index of Federal Specifications, Standards and Commercial Item Descriptions, available on the DoD Acquisition Streamlining and Standardization Information System (ASSIST) website, or listed in other agency index shall identify each document’s approval date and the dates of any applicable amendments and revisions. Do not use general identification references, such as "the issue in effect on the date of the solicitation." Contracting offices will not normally furnish these cited documents with the solicitation, except when- (1) The requirements document must be furnished with the solicitation to enable prospective contractors to make a competent evaluation of the solicitation; (2) In the judgment of the contracting officer, it would be impracticable for prospective contractors to obtain the documents in reasonable time to respond to the solicitation; or (3) A prospective contractor requests a copy of a Government promulgated requirements document. (b) Contracting offices shall clearly identify in the solicitation any pertinent documents not listed in the GSA Index of Federal Specifications, Standards and Commercial Item Descriptions or ASSIST. Such documents shall be furnished with the solicitation or specific instructions shall be furnished for obtaining or examining such documents. (c) When documents refer to other documents, such references shall– (1) Be restricted to documents, or appropriate portions of documents, that apply in the acquisition; (2) Cite the extent of their applicability; (3) Not conflict with other documents and provisions of the solicitation; and (4) Identify all applicable first tier references. (d) (1) The GSA Index of Federal Specifications, Standards and Commercial Item Descriptions, FPMR Part 101–29, may be viewed at the ASSIST website at https://assist.dla.mil . (2) Most unclassified Defense specifications and standards may be downloaded from the ASSIST website at https://assist.dla.mil . (3) Defense documents not available from the ASSIST website may be ordered from the Defense Standardization Program Office by— (i) Using the ASSIST feedback module at https://assist.dla.mil/feedback ; or (ii) Contacting the Defense Standardization Program Office by telephone at 571–767–6888 or email at assisthelp@dla.mil . (4) The FIPS PUBS may be obtained from— http://www.itl.nist.gov/fipspubs/ , or purchased from the- Superintendent of Documents, U.S. Government Publishing Office, Washington, DC 20402, Telephone (202) 512-1800, Facsimile (202) 512-2250; or National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161, Telephone (703) 605-6000, Facsimile (703) 605-6900, Email: orders@ntis.gov . (e) Agencies may purchase some nongovernment standards, including voluntary consensus standards, from the National Technical Information Service’s Fedworld Information Network. Agencies may also obtain nongovernment standards from the standards developing organization responsible for the preparation, publication, or maintenance of the standard, or from an authorized document reseller. The National Institute of Standards and Technology can assist agencies in identifying sources for, and content of, nongovernment standards. DoD activities may obtain from the Defense Standardization Program Office those nongovernment standards, including voluntary consensus standards, adopted for use by defense activities.
