AF PGI 5343.103-90 Types of Contract Modifications

(a) This table is a guide for buyers and contracting officers to help determine the appropriate authority for issuance of specific types of modifications. The specific facts surrounding the individual modification should always be analyzed. Contracting officers may use the Modification Authority Justification Template to document their decision. The general rule is to cite the explicit authority, which is that authority expressly written into the contract, before citing a more general authority such as “By Mutual Agreement between both Parties”. 10 U.S.C Chapter 137 should not be used as it is too broad and does not address modification authority. FAR 1.602, Authority for contracting officers, should not be used because it only defines the authority of the contracting officer (who is only one party to the original agreement) and does not cite a pre-agreed to condition or authority within the original contract that would allow a change.

(b) Explicit authority can be provided in the general clauses contained in Section I of the contract. The Changes clause (FAR 52.243-1), Definitization clause (FAR 52.216-25), or Options clauses (FAR 52.217-6 thru 9) are examples. Explicit authority can also be provided for under special contract requirements contained in Section H of the contract. Finally, explicit authority may be provided for under provisions contained elsewhere in the contract, such as the SOW.

(c) When citing a specific clause/provision as the authority for the modification, ensure the contract contains that specific clause/provision.

SMC PGI 5343 Contract Modifications

SMC PGI 5343.102-90 General

(a) When issuing a modification to an existing contract (or order), the contracting officer should consider documenting the scope determination in writing. See the SMC Scope Determination Guide and sample Memorandum for Record (MFR). Written scope determinations are not generally necessary for administrative modifications that do not impact the substantive rights of the parties (e.g., a change in the paying office or the appropriation data) or unilateral modifications that are authorized by clauses other than the Changes clause (e.g., property clause, options clause).​

(b) If the legal reviewer does not find the contracting officer’s scope determination to be legally sufficient and the contracting officer disagrees with the legal reviewer’s opinion, the contracting officer should elevate the dispute to the COCO and SCO quickly to ensure the issue is resolved in a timely manner.
