FAR 48.001—Definitions.
Plain-English Summary
FAR 48.001 is the definitions section for the value engineering part of the FAR, and it supplies the vocabulary used to calculate, allocate, and administer savings from value engineering change proposals (VECPs). It defines acquisition savings, instant contract savings, concurrent contract savings, future contract savings, collateral costs, collateral savings, contracting office, contractor’s development and implementation costs, future unit cost reduction, Government costs, instant contract, instant unit cost reduction, negative instant contract savings, net acquisition savings, sharing base, sharing period, unit, and value engineering proposal in the special context of A-E contracts. These definitions matter because they control how savings are measured, when they are measured, which contracts are included, and how much the contractor may share in the savings. In practice, the section determines whether a VECP produces a payment, a price reduction, or no net benefit at all, and it affects both the contractor’s incentive to propose changes and the Government’s ability to capture savings across current and future contracts. Because the terms are highly technical, small differences in contract type, quantity changes, option exercise, or transfer of the acquisition to another office can materially change the financial outcome. The section is therefore the foundation for administering value engineering clauses and for resolving disputes over what counts as savings, costs, and the sharing base.
Key Rules
Acquisition savings are broad
Acquisition savings include instant, concurrent, and future contract savings from applying a VECP to contracts awarded by the same contracting office or its successor for essentially the same unit. The definition is designed to capture savings across the affected procurement stream, not just on the contract where the proposal was submitted.
Instant savings are contract-specific
Instant contract savings are the net cost reductions on the contract under which the VECP is submitted and accepted. They equal the instant unit cost reduction multiplied by the number of instant contract units affected, minus the contractor’s allowable development and implementation costs.
Concurrent and future savings differ by timing
Concurrent contract savings are reductions on other contracts that are already definitized and ongoing when the VECP is accepted, while future contract savings are based on future contract units in the sharing base. Future savings can also include later quantity increases on the instant contract from modifications, options, additional orders, or multiyear funding after acceptance.
Collateral costs and savings are separate
Collateral costs are agency operating, maintenance, logistics support, or Government-furnished property costs. Collateral savings are measurable net reductions in those collateral costs caused by the VECP, and they are counted separately from acquisition savings whether or not the acquisition price changes.
Government costs reduce net savings
Government costs are the agency’s direct costs of developing and implementing the VECP, such as increased testing, operations, maintenance, and logistics support. Normal administrative processing costs are excluded, and these Government costs are subtracted in determining net acquisition savings.
Instant contract has a narrow meaning
The instant contract is the contract under which the VECP is submitted, but it does not include later quantity increases from modifications, options, additional orders, or, for multiyear contracts, quantities funded after VECP acceptance. For fixed-price contracts with prospective price redetermination, it means only the period for which firm prices have been established.
Future unit cost reduction is projected
Future unit cost reduction is the instant unit cost reduction adjusted for projected learning or quantity changes during the sharing period, as the contracting officer considers necessary. It is set when the VECP is accepted and generally applies throughout the sharing period unless recalculation is justified by significantly different conditions, or unless it is used for a lump-sum payment that cannot later be revised.
Sharing base and sharing period control payment scope
The sharing base is the number of affected end items on contracts of the contracting office accepting the VECP, and the sharing period is the period from acceptance of the first unit incorporating the VECP to a date or event set by the contracting officer. These terms determine how much of the savings stream is eligible for sharing and for how long.
Unit and A-E proposal definitions are agreement-based
A unit is the item or task the contracting officer and contractor agree the VECP applies to. For A-E contracts, a value engineering proposal is a change proposal developed by Government employees or contractor value engineering personnel under contract to provide value engineering services for the contract or program.
Responsibilities
Contracting Officer
Identify the correct contract scope, sharing base, and sharing period; determine whether savings are instant, concurrent, future, or collateral; decide whether future unit cost reduction should be recalculated; and apply the definitions consistently when evaluating VECPs and calculating any sharing payment or price adjustment.
Contractor
Prepare and submit VECPs with supportable cost and savings data; track allowable development and implementation costs; distinguish instant contract units from later quantity increases; and provide enough information for the contracting officer to calculate savings accurately.
Agency
Track collateral costs and collateral savings, including operating, maintenance, logistics support, and Government-furnished property impacts; ensure savings are measured across affected contracts when the contracting office changes or the acquisition is transferred; and account for direct Government costs associated with VECP implementation.
Contracting Office or Successor Office
Recognize that acquisition savings may extend to contracts awarded by the same office or its successor; coordinate across transferred acquisitions or joint acquisition actions; and ensure that concurrent and future savings are captured on affected contracts within its responsibility.
Value Engineering Personnel / A-E Support Personnel
When working under an A-E contract, develop or support value engineering proposals in the manner contemplated by the contract and ensure the proposal fits the special A-E definition used in this part.
Practical Implications
The biggest practical issue is getting the math and the timing right: a VECP can look profitable until allowable contractor costs, Government costs, and collateral effects are included, or until future savings are limited by the sharing base and sharing period.
Contracting officers should be careful not to treat later quantity increases on the instant contract as part of the instant contract definition; those quantities may instead affect future savings or be excluded depending on the clause and timing.
Contractors often underestimate the importance of documenting development and implementation costs, which can directly reduce instant savings and can turn a proposal into negative instant contract savings.
Collateral savings are easy to miss because they are outside the contract price; agencies should evaluate lifecycle impacts such as maintenance, logistics, and Government-furnished property changes, not just procurement price.
Because the contracting office may include a successor office or a joint acquisition office, parties should coordinate early when contracts are transferred or administered across organizations to avoid double counting or omitting savings.
Official Regulatory Text
As used in this part- Acquisition savings means savings resulting from the application of a value engineering change proposal (VECP) to contracts awarded by the same contracting office or its successor for essentially the same unit. Acquisition savings include- (1) Instant contract savings, that are the net cost reductions on the contract under which the VECP is submitted and accepted, and that are equal to the instant unit cost reduction multiplied by the number of instant contract units affected by the VECP, less the contractor’s allowable development and implementation costs; (2) Concurrent contract savings, that are net reductions in the prices of other contracts that are definitized and ongoing at the time the VECP is accepted; and (3) Future contract savings, that are the product of the future unit cost reduction multiplied by the number of future contract units in the sharing base. On an instant contract, future contract savings include savings on increases in quantities after VECP acceptance that are due to contract modifications, exercise of options, additional orders, and funding of subsequent year requirements on a multiyear contract. Collateral costs means agency costs of operation, maintenance, logistic support, or Government-furnished property. Collateral savings means those measurable net reductions resulting from a VECP in the agency’s overall projected collateral costs, exclusive of acquisition savings, whether or not the acquisition cost changes. Contracting office includes any contracting office that the acquisition is transferred to, such as another branch of the agency or another agency’s office that is performing a joint acquisition action. Contractor’s development and implementation costs means those costs the contractor incurs on a VECP specifically in developing, testing, preparing, and submitting the VECP, as well as those costs the contractor incurs to make the contractual changes required by Government acceptance of a VECP. Future unit cost reduction means the instant unit cost reduction adjusted as the contracting officer considers necessary for projected learning or changes in quantity during the sharing period. It is calculated at the time the VECP is accepted and applies either- (1) Throughout the sharing period, unless the contracting officer decides that recalculation is necessary because conditions are significantly different from those previously anticipated, or (2) To the calculation of a lump-sum payment, that cannot later be revised. Government costs means those agency costs that result directly from developing and implementing the VECP, such as any net increases in the cost of testing, operations, maintenance, and logistics support. The term does not include the normal administrative costs of processing the VECP or any increase in instant contract cost or price resulting from negative instant contract savings, except that for use in 52.248-3 , see the definition at 52.248-3 (b). Instant contract means the contract under which the VECP is submitted. It does not include increases in quantities after acceptance of the VECP that are due to contract modifications, exercise of options, or additional orders. If the contract is a multiyear contract, the term does not include quantities funded after VECP acceptance. In a fixed-price contract with prospective price redetermination, the term refers to the period for which firm prices have been established. Instant unit cost reduction means the amount of the decrease in unit cost of performance (without deducting any contractor’s development or implementation costs) resulting from using the VECP on the instant contract. In service contracts, the instant unit cost reduction is normally equal to the number of hours per line-item task saved by using the VECP on the instant contract, multiplied by the appropriate contract labor rate. Negative instant contract savings means the increase in the instant contract cost or price when the acceptance of a VECP results in an excess of the contractor’s allowable development and implementation costs over the product of the instant unit cost reduction multiplied by the number of instant contract units affected. Net acquisition savings means total acquisition savings, including instant, concurrent, and future contract savings, less Government costs. Sharing base means the number of affected end items on contracts of the contracting office accepting the VECP. Sharing period means the period beginning with acceptance of the first unit incorporating the VECP and ending at a calendar date or event determined by the contracting officer for each VECP. Unit means the item or task to which the contracting officer and the contractor agree the VECP applies. Value engineering proposal means, in connection with an A-E contract, a change proposal developed by employees of the Federal Government or contractor value engineering personnel under contract to an agency to provide value engineering services for the contract or program.
