    FAR 22.404-12Labor standards for contracts containing construction requirements and option provisions that extend the term of the contract.

    Plain-English Summary

    FAR 22.404-12 explains how labor standards are handled when a construction contract has option periods that extend the contract term, including contracts with substantial and segregable construction work and certain indefinite-delivery/indefinite-quantity (IDIQ) construction requirements. Its purpose is to make sure the contract reflects the current wage determination when an option is exercised, while also giving the contracting officer approved ways to account for resulting labor-cost changes in fixed-price contracts. The section covers when the contracting officer must modify the contract to insert the most current wage determination, how that wage determination applies to task orders issued during an option period, and what pricing mechanisms may be used to adjust fixed prices for wage changes. It also addresses the special rule that the wage determination in effect at option exercise governs the full performance period of task orders issued during that option period. In practice, this section is about keeping Davis-Bacon/Construction Wage Rate Requirements compliance current at option exercise and making sure the contract’s pricing structure fairly and lawfully handles wage escalation or reduction. For contractors, it affects how option pricing is proposed and how labor-cost risk is allocated; for contracting officers, it requires advance planning so the solicitation and contract include a suitable adjustment method before award.

    Key Rules

    Update wage determination at option exercise

    Each time the contracting officer exercises an option to extend the term of a construction contract, or a contract with substantial and segregable construction work, the contract must be modified to incorporate the most current wage determination. The wage determination in effect at option exercise becomes part of the contract for the extended period.

    IDIQ task orders use option-period wage rate

    For construction IDIQ contracts with options to extend the term, the wage determination incorporated when the option is exercised must be used for task orders issued during that option period. That wage determination remains effective for the entire performance period of those task orders without further revision.

    Fixed-price contracts need an adjustment clause

    The contracting officer must include a clause in fixed-price contracts that selects one approved method to account for labor-cost increases or decreases caused by the new or revised wage determination at option exercise. The chosen method must be suitable to the Government’s interest and built into the solicitation and contract.

    Separate pricing for each option period

    One permitted method is to let offerors bid or propose separate prices for each option period. Under this approach, the contract price is not further adjusted when the new wage determination is incorporated at option exercise. This method is generally used for construction-only contracts expected to last no more than three years.

    Pre-set pricing formula method

    Another method is to use a separately specified pricing formula that adjusts the contract price or labor unit price at option exercise. The contract must state the formula in advance, and the contracting officer applies the new wage determination and the agreed pricing method together, without any additional wage-based adjustment.

    Economic-indicator percentage method

    The contracting officer may base the adjustment on a percentage rate derived from a published economic indicator incorporated into the solicitation and contract. The clause must designate the labor-cost portion subject to adjustment, and the default assumption is that labor equals 50 percent of the contract price unless a different percentage is justified before solicitation.

    Actual wage-and-fringe adjustment method

    The contract may use a computation method that adjusts price based on the contractor’s actual increase or decrease in wages and fringe benefits needed to comply with, or voluntarily made because of, the revised wage determination. This method is generally appropriate when the contract is mainly services subject to the Service Contract Labor Standards statute and the construction work is substantial and segregable.

    Responsibilities

    Contracting Officer

    Must modify the contract each time an option to extend the term is exercised to incorporate the current wage determination. Must ensure the contract includes a fixed-price adjustment clause selecting one approved method for handling wage changes, and must choose a method suitable to the Government’s interest before award.

    Contracting Officer

    For IDIQ construction contracts with option periods, must ensure the wage determination in effect at option exercise is applied to task orders issued during that option period and that no further revision is made for the life of those task orders.

    Contracting Officer

    Must determine, before solicitation, whether a percentage other than 50 percent is a more appropriate estimate of the labor portion for the economic-indicator method, and must incorporate the chosen indicator and pricing method into the solicitation and contract.

    Contractor

    Must price option periods in accordance with the contract’s selected adjustment method and understand that the wage determination may change at option exercise. Must comply with the updated wage determination for the extended period and, where applicable, provide actual wage and fringe data needed to support a contract adjustment.

    Agency

    Must support acquisition planning so the solicitation and contract structure include an appropriate wage-adjustment mechanism for option periods, especially where construction work is mixed with services or where long-term pricing risk needs to be managed.

    Practical Implications

    1

    Contractors should expect wage rates to be refreshed when an option is exercised, so option pricing must account for labor escalation risk instead of assuming the original wage determination will stay in place.

    2

    Contracting officers need to choose the adjustment method up front; if the contract does not contain a proper clause, the Government may have difficulty lawfully or fairly handling wage-driven price changes at option exercise.

    3

    For IDIQ construction work, the wage determination tied to the option period controls all task orders issued in that period, so ordering activity timing matters and task orders should not be treated as if they can pick up later wage revisions mid-performance.

    4

    The 50 percent labor-cost assumption under the economic-indicator method is a default, not a universal rule; using it without checking whether a different percentage is more accurate can distort pricing and create disputes.

    5

    The actual wage-and-fringe method is best suited to mixed contracts where services predominate and construction is substantial but separable; using it in the wrong setting can make administration cumbersome and inconsistent with the rule’s intended use.

    6

    A common pitfall is forgetting that the wage determination is incorporated at option exercise, not at task-order award or later during performance, which can lead to noncompliant pricing and administration errors.

    Official Regulatory Text

    (a) Each time the contracting officer exercises an option to extend the term of a contract for construction, or a contract that includes substantial and segregable construction work, the contracting officer must modify the contract to incorporate the most current wage determination. (b) If a contract with an option to extend the term of the contract has indefinite-delivery or indefinite-quantity construction requirements, the contracting officer must incorporate the wage determination incorporated into the contract at the exercise of the option into task orders issued during that option period. The wage determination will be effective for the complete period of performance of those task orders without further revision. (c) The contracting officer must include in fixed-price contracts a clause that specifies one of the following methods, suitable to the interest of the Government, to provide an allowance for any increases or decreases in labor costs that result from the inclusion of the current wage determination at the exercise of an option to extend the term of the contract: (1) The contracting officer may provide the offerors the opportunity to bid or propose separate prices for each option period. The contracting officer must not further adjust the contract price as a result of the incorporation of a new or revised wage determination at the exercise of each option to extend the term of the contract. Generally, this method is used in construction-only contracts (with options to extend the term) that are not expected to exceed a total of 3 years. (2) The contracting officer may include in the contract a separately specified pricing method that permits an adjustment to the contract price or contract labor unit price at the exercise of each option to extend the term of the contract. At the time of option exercise, the contracting officer must incorporate a new wage determination into the contract, and must apply the specific pricing method to calculate the contract price adjustment. An example of a contract pricing method that the contracting officer might separately specify is incorporation in the solicitation and resulting contract of the pricing data from an annually published unit pricing book (e.g. , the U.S. Army Computer-Aided Cost Estimating System or similar commercial product), which is multiplied in the contract by a factor proposed by the contractor ( e.g. , .95 or 1.1 ). At option exercise, the contracting officer incorporates the pricing data from the latest annual edition of the unit pricing book, multiplied by the factor agreed to in the basic contract. The contracting officer must not further adjust the contract price as a result of the incorporation of the new or revised wage determination. (3) The contracting officer may provide for a contract price adjustment based solely on a percentage rate determined by the contracting officer using a published economic indicator incorporated into the solicitation and resulting contract. At the exercise of each option to extend the term of the contract, the contracting officer will apply the percentage rate, based on the economic indicator, to the portion of the contract price or contract unit price designated in the contract clause as labor costs subject to the provisions of the Construction Wage Rate Requirements statute. The contracting officer must insert 50 percent as the estimated portion of the contract price that is labor unless the contracting officer determines, prior to issuance of the solicitation, that a different percentage is more appropriate for a particular contract or requirement. This percentage adjustment to the designated labor costs must be the only adjustment made to cover increases in wages and/or benefits resulting from the incorporation of a new or revised wage determination at the exercise of the option. (4) The contracting officer may provide a computation method to adjust the contract price to reflect the contractor’s actual increase or decrease in wages and fringe benefits (combined) to the extent that the increase is made to comply with, or the decrease is voluntarily made by the contractor as a result of incorporation of, a new or revised wage determination at the exercise of the option to extend the term of the contract. Generally, this method is appropriate for use only if contract requirements are predominately services subject to the Service Contract Labor Standards statute and the construction requirements are substantial and segregable. The methods used to adjust the contract price for the service requirements and the construction requirements would be similar.
