FAR 52.252—[Reserved]

Solicitation Provisions Incorporated by Reference.

FAR 52.252-1 tells offerors that a solicitation may incorporate one or more solicitation provisions by reference instead of printing the full text in the solicitation. It explains that those incorporated provisions have the same force and effect as if they were included in full, and that the contracting officer must provide the full text on request. The clause also warns offerors that some incorporated provisions contain blocks or blanks that must be completed and returned with the quotation or offer, and it allows the offeror to satisfy those requirements by identifying the provision and supplying the required information rather than reproducing the entire provision. Finally, it addresses electronic access by allowing the solicitation to list Internet addresses where the full text of the incorporated provisions can be found. In practice, this provision is about notice, accessibility, and administrative efficiency: it lets agencies keep solicitations shorter while still binding offerors to the incorporated terms, and it puts the burden on offerors to locate, understand, and complete any required provision data before submitting a responsive offer.

Clauses Incorporated by Reference.

FAR 52.252-2, Clauses Incorporated by Reference, tells contractors and contracting officers how incorporated clauses become part of a contract even when they are not printed in full. This clause covers three main topics: the legal effect of incorporation by reference, the contracting officer’s duty to provide the full text on request, and the option to identify Internet addresses where the full text can be accessed electronically. In practice, it is a notice clause that helps keep solicitations and contracts shorter while still making all incorporated requirements binding. It matters because contractors are charged with complying with incorporated clauses whether or not they appear in the body of the contract, so they must know where to find them and understand that they carry the same force and effect as full-text clauses. The clause also supports transparency and accessibility by requiring the Government to make the text available and by allowing electronic access references to be listed in the contract.

Alterations in Solicitation.

FAR 52.252-3, Alterations in Solicitation, is a solicitation provision used when the Government needs to revise or supplement other parts of a solicitation that apply only during the solicitation phase. It tells contracting officers how to make those changes formally and transparently, and it limits the provision’s use to solicitation-stage matters rather than contract performance terms. The provision also requires clear identification of exactly what is being altered, so offerors can see what language has changed and respond accordingly. In practice, this provision helps prevent confusion, reduces the risk of inconsistent solicitation documents, and supports fair competition by making amendments or special changes easy to locate and understand. It is prescribed by FAR 52.107(c), and it is not to be used to alter provisions that are authorized for use with a deviation. For contractors, it signals that the solicitation contains special changes that may affect proposal preparation, compliance, pricing, or evaluation, so careful review is essential.

Alterations in Contract.

FAR 52.252-4, Alterations in Contract, is a short but important clause used when the government needs to revise or supplement other parts of a solicitation or contract after award, or to modify solicitation provisions that will apply after award. The section explains when the clause is prescribed, namely under FAR 52.107(d), and it makes clear that it is used to identify specific changes to the contract text rather than to create new substantive rights by itself. It also limits use of the clause by excluding clauses authorized for use with a deviation, which means agencies should not rely on this clause to bypass deviation procedures or to alter clauses in a way that conflicts with approved deviations. In practice, the clause serves as a clean drafting tool: it tells the reader exactly what language is being changed, added, or replaced, and it helps avoid ambiguity about which contract terms control. Because the clause requires clear identification of the alterations, it is especially important for contract administration, interpretation, and later disputes over which version of a term applies. For contractors and contracting officers, the main significance is ensuring that any post-award changes or solicitation supplements are explicit, traceable, and properly incorporated into the contract record.

Authorized Deviations in Provisions.

FAR 52.252-5 tells contracting officers how to identify a solicitation provision when the Government is using an authorized deviation from the standard FAR text or from a supplemental regulation’s standard provision. It covers the required citation format for both FAR provisions and supplemental provisions, including the need to keep the original number, title, and date, and to add “(DEVIATION)” in the proper place. For supplemental provisions, it also requires the contracting officer to name the regulation and identify the CFR chapter. The clause exists to make deviations transparent to offerors, so they can tell when a solicitation provision is not the standard version and can evaluate the changed language correctly. In practice, this helps prevent confusion, supports fair competition, and creates a clear record that the solicitation departs from the baseline regulatory text under an authorized deviation.

Authorized Deviations in Clauses.

FAR 52.252-6 tells contracting officers how to identify clauses that are being used with an authorized deviation in solicitations and contracts. It covers both FAR clauses and supplemental agency clauses, and it requires the clause citation to stay tied to the original clause number, title, and date while clearly showing that a deviation exists. For FAR clauses, the marker is “(DEVIATION)” after the date; for supplemental clauses, the marker is “(DEVIATION)” after the name of the regulation. The section exists to preserve transparency, avoid confusion about which version of a clause applies, and make it easier for offerors, contractors, auditors, and reviewers to understand that the clause text is not the standard FAR or agency text. In practice, this clause is a labeling and notice requirement: it does not itself authorize deviations, but it ensures that any approved deviation is clearly identified wherever the clause appears.
