    FAR 48.101General.

    Plain-English Summary

    FAR 48.101 explains what value engineering is and sets out the two basic ways it can be used in federal contracting: a voluntary, incentive-based approach and a mandatory, Government-directed program approach. It defines value engineering as a formal technique for finding ways to perform more economically without reducing essential functions or characteristics, with the goal of lowering acquisition, operation, or support costs. The section also distinguishes between contractor-initiated value engineering change proposals (VECPs), where the contractor uses its own resources and may share in savings if the proposal is accepted, and Government-required value engineering programs, where the contractor is paid to perform a specified level of effort as a separate contract item. It further notes that no savings sharing is allowed in architect-engineer contracts, while other contracts with a program clause do allow sharing, but at a lower rate than the voluntary approach. In practice, this section matters because it frames how value engineering is structured, who bears the development cost, when the contractor can recover costs or earn a share of savings, and how agencies should target value engineering effort toward areas with meaningful savings potential.

    Key Rules

    Value engineering definition

    Value engineering is a formal method for finding more economical ways to perform contract work without impairing essential functions or characteristics. Its purpose is to reduce acquisition, operation, or support costs while preserving required performance.

    Voluntary incentive approach

    Under the first approach, contractor participation is voluntary and the contractor uses its own resources to develop and submit VECPs. If the Government accepts the proposal, the contract provides for sharing savings and paying allowable development and implementation costs.

    No automatic Government cost increase

    The voluntary approach is intended not to increase Government costs by itself. The contractor takes the risk of developing the proposal, and payment occurs only if the VECP is accepted under the contract terms.

    Mandatory program approach

    Under the second approach, the Government may require a specific value engineering program and pay for that effort as a separately priced contract item. The contractor must perform the scope and level of effort set out in the Government’s program plan.

    Savings sharing rules differ

    Contracts with a mandatory program clause generally share savings on accepted VECPs, but at a lower percentage than the voluntary approach. However, architect-engineer contracts do not permit value engineering sharing.

    Targeting meaningful savings

    The purpose of the mandatory program is to direct contractor effort toward areas where value engineering can produce substantial savings while still meeting the functional requirements of the end item.

    Responsibilities

    Contracting Officer / Government

    Decide whether to use a voluntary incentive approach or require a mandatory value engineering program. When using a mandatory program, define the scope and level of effort in the contract schedule, pay for that effort as a separate item, and ensure the program targets areas with real savings potential consistent with required functions.

    Contractor

    For voluntary VECPs, decide whether to invest its own resources to develop and submit proposals for more economical performance methods. For mandatory programs, perform the required value engineering effort at the scope and level of effort specified in the contract and submit proposals as required.

    Contract Administration / Program Officials

    Evaluate VECPs, determine whether proposed changes preserve essential functions and characteristics, and administer savings-sharing and allowable-cost provisions in accordance with the contract type and applicable clause.

    Agency

    Use value engineering in a way that supports cost reduction without sacrificing mission needs, and ensure architect-engineer contracts are not structured to allow prohibited savings sharing.

    Practical Implications

    1

    Contractors should understand that voluntary VECP development is usually at their own risk unless the proposal is accepted, so they need to screen ideas carefully before investing effort.

    2

    Contracting officers must be precise when drafting a mandatory value engineering program because the contractor’s obligation and payment depend on the stated scope and level of effort.

    3

    Architect-engineer contracts are a special case: no value engineering savings sharing is allowed, so parties should not assume the same incentives apply as in other contract types.

    4

    A common pitfall is confusing the two approaches and mispricing or misadministering savings-sharing rights, especially where a program clause is present.

    5

    Value engineering should focus on changes that reduce cost without harming required performance; proposals that compromise essential functions are outside the intended purpose of this section.

    Official Regulatory Text

    (a) Value engineering is the formal technique by which contractors may (1) voluntarily suggest methods for performing more economically and share in any resulting savings or (2)be required to establish a program to identify and submit to the Government methods for performing more economically. Value engineering attempts to eliminate, without impairing essential functions or characteristics, anything that increases acquisition, operation, or support costs. (b) There are two value engineering approaches: (1) The first is an incentive approach in which contractor participation is voluntary and the contractor uses its own resources to develop and submit any value engineering change proposals (VECP’s). The contract provides for sharing of savings and for payment of the contractor’s allowable development and implementation costs only if a VECP is accepted. This voluntary approach should not in itself increase costs to the Government. (2) The second approach is a mandatory program in which the Government requires and pays for a specific value engineering program effort. The contractor must perform value engineering of the scope and level of effort required by the Government’s program plan and included as a separately priced item of work in the contract Schedule. No value engineering sharing is permitted in architect engineer contracts. All other contracts with a program clause share in savings on accepted VECP’s, but at a lower percentage rate than under the voluntary approach. The objective of this value engineering program requirement is to ensure that the contractor’s value engineering effort is applied to areas of the contract that offer opportunities for considerable savings consistent with the functional requirements of the end item of the contract.
