Contract Modifications, Options & Change Management for SDVOSBs

Winning the set-aside is only the start — the contract changes constantly after award, and a small prime that performs directed work without a signed modification, misses an equitable-adjustment deadline, or lets an out-of-scope change ride is giving the work away. These plain-English pages take one change mechanism at a time — the bilateral and unilateral modifications, the change order under the Changes clause and the equitable adjustment that pays for it, the constructive change, the options that extend your term and quantity, the novation and change-of-name agreements that move a contract to a successor, and the terminations for convenience and default that end it. Each has an at-a-glance card, its controlling FAR citation, when you see it, how to handle it, and the SDVOSB-specific angle — from recertification on a novation or option to the CPARS damage of a default.

  1. LaunchedPublished the federal contract modifications, options & change management reference covering how a federal contract changes after award — the bilateral supplemental agreement and the unilateral modification (FAR 43.103), the change order under the Changes clause (FAR 52.243-1), the administrative change (FAR 43.101), the equitable adjustment and the Request for Equitable Adjustment (FAR 43.204 / 43.205), the constructive change doctrine, the options to extend the term and quantity (FAR 52.217-8, 52.217-9, and the Subpart 17.2 quantity options 52.217-6/-7), the novation and change-of-name agreements (FAR Subpart 42.12), and the terminations for convenience and default (FAR Part 49 / 52.249-2 / 52.249-8) — each with an at-a-glance quick-facts card, a when-you-see-it list, a key-features table, an SDVOSB-specific angle, a how-to-handle-it checklist, watch-outs, FAQPage, Article, Dataset, and BreadcrumbList structured data, primary-source FAR citations, and cross-links into the glossary, regulation explainers, clauses, forms, contract types, protest & dispute forums, compliance deadlines, how-to guides, FAQ, and the limitations-on-subcontracting, price-to-win, size-standard, and set-aside eligibility calculators.

Modification Mechanisms

Bilateral Mod
Bilateral (Supplemental Agreement) ModificationA contract modification signed by both the contractor and the contracting officer. FAR calls it a supplemental agreement, and it's how the government and an SDVOSB agree on a change and its price and schedule impact — usually recorded on an SF 30.
Unilateral Mod
Unilateral ModificationA contract modification signed only by the contracting officer, used for changes the government is authorized to make on its own — administrative changes, change orders under the Changes clause, exercising an option, and adding funds. Your remedy for the cost impact is an equitable adjustment.
Change Order
Change Order (Changes Clause)A written order, signed by the contracting officer under the Changes clause, directing the contractor to make a change within the general scope of the contract. The contractor must perform and is entitled to an equitable adjustment for the cost and time impact.
Admin Change
Administrative ChangeA unilateral contract change that does not affect the substantive rights of the parties — for example, a change in the paying office, an appropriation data correction, or an address update. It's issued on an SF 30 by the contracting officer and needs no equitable adjustment.

Adjustments & Recovery

EA
Equitable AdjustmentThe adjustment to contract price and/or schedule that the government owes a contractor when a change increases the cost or time of performance. It is the contractor's remedy under the Changes clause and other adjustment clauses, and it's meant to leave the contractor neither better nor worse off.
REA
Request for Equitable Adjustment (REA)The formal, documented request a contractor submits to the contracting officer asking for an equitable adjustment to price and/or schedule after a change or government-caused impact. An REA is a negotiation tool — distinct from, and usually a precursor to, a Contract Disputes Act claim.
Constructive Change
Constructive ChangeWork beyond the contract's requirements that the government effectively causes — through informal direction, over-inspection, defective specs, or interference — without ever issuing a formal change order. The doctrine lets the contractor recover an equitable adjustment as though a change order had been issued.

Options & Duration

52.217-8 Option
Option to Extend Services (FAR 52.217-8)A clause that lets the government require the contractor to keep performing services for up to six months beyond the contract, at the rates in effect, to bridge a gap while a follow-on is competed. It's exercised by unilateral modification and is a common cause of extended set-aside performance.
52.217-9 Option
Option to Extend the Term (FAR 52.217-9)The clause that creates priced option periods — the classic 'option years' — that the government may exercise to extend the contract's term. It's exercised by unilateral modification after preliminary notice, and it's why so many federal contracts run a base year plus option years.
Quantity Option
Options for Increased Quantity (FAR 17.2)Priced options that let the government buy additional supplies or services beyond the base quantity, at rates set at award. Exercised by unilateral modification under FAR 52.217-6 (stated in the schedule) or 52.217-7 (increased quantity for a separately priced line item).

Novation & Termination

Novation
Novation AgreementA three-party agreement in which the government recognizes a successor in interest to a contract after the original contractor transfers all the assets or the part performing the contract — for example, in an acquisition or reorganization. It's how a contract lawfully moves to a new legal entity, and it can trigger SDVOSB recertification.
Change of Name
Change-of-Name AgreementA two-party agreement in which the government recognizes a contractor's change of legal name when only the name changes — the same legal entity keeps performing, with no transfer of assets. Simpler than a novation, but still required to keep the contract records and payments aligned.
T4C
Termination for ConvenienceThe government's right to end a contract, in whole or in part, when it's in the government's interest — not because of any contractor fault. The contractor stops work as directed and is entitled to recover its allowable incurred costs, a reasonable profit on work done, and settlement expenses.
T4D
Termination for DefaultThe government's right to end a contract because of the contractor's failure to perform — to deliver on time, make progress, or meet other contract terms. It's the most damaging termination: the contractor can be liable for reprocurement costs and it seriously harms past performance and future eligibility.

Don’t give the change away

The primes that stay profitable after award get the modification signed before they perform, price the equitable adjustment like a bid, and re-run the self-performance math over every option and added scope. Model your limitations on subcontracting, price the change, and keep your SDVOSB eligibility intact through recertification.
