FAR 52.215—[Reserved]

Instructions to Offerors-Competitive Acquisition.

FAR 52.215-1, Instructions to Offerors—Competitive Acquisition, tells offerors how to prepare, submit, modify, revise, and withdraw proposals in a competitive federal procurement. It also defines key terms used in the provision, including discussions, writing, proposal modification, proposal revision, and time, so both offerors and contracting officers apply the same rules. The provision explains how amendments to the solicitation must be acknowledged, what information must appear on the first page of the proposal, and how proposals must be packaged and addressed when paper submission is required. It sets the basic timeliness rules for receipt of proposals, including what counts as a late proposal, when late proposals may still be considered, how to prove receipt, and what happens when an emergency or unanticipated event interrupts normal Government operations. It also addresses withdrawal of proposals before award and allows offerors to propose any item or combination of items unless the solicitation says otherwise. In practice, this provision is critical because it governs whether a proposal is responsive to the solicitation process, whether it is timely, and whether the Government may lawfully consider it at all.

Audit and Records-Negotiation.

FAR 52.215-2, Audit and Records—Negotiation, is the government’s core contract clause for access to contractor records in negotiated procurements. It covers what counts as “records,” the government’s right to examine and audit records for cost-reimbursement, incentive, time-and-materials, labor-hour, and price-redeterminable contracts, the government’s right to review records tied to certified cost or pricing data, the Comptroller General’s access rights, the right to examine supporting records for cost, funding, and performance reports, how long records must be retained and made available, and the contractor’s duty to flow the clause down to certain subcontracts. The clause also includes Alternate I, which expands access rights to an Inspector General and broadens subcontract coverage, and Alternate II, which incorporates the OMB Uniform Guidance audit requirements for certain contracts. In practice, this clause gives the government a broad audit and inspection tool to verify pricing, incurred costs, reported data, and contract performance, while also setting retention and subcontract flowdown obligations that contractors must manage carefully. It matters because failure to maintain, produce, or flow down required records can create audit findings, payment disputes, pricing challenges, and potential contractual noncompliance.

Request for Information or Solicitation for Planning Purposes.

FAR 52.215-3 is a planning-purpose provision used when the Government wants information from industry but does not intend to award a contract from the response. It covers three core topics: the Government’s no-award/no-payment position, the rule that any response is information only and not a proposal, and the requirement to state the specific purpose of the request. In practice, this provision is used for market research, planning, and other pre-solicitation information gathering where the agency wants contractor input without creating an offer-and-acceptance process. It also protects the Government from implied obligations to pay for responses, except where the costs are otherwise allowable under the FAR’s bid and proposal cost rules at 31.205-18. For contractors, the provision signals that responding is voluntary and that the submission will not be treated as a binding offer or a proposal for award purposes. For contracting officers, it is a drafting tool that helps avoid confusion between market research and a true solicitation.

Facsimile Proposals.

FAR 52.215-5, Facsimile Proposals, tells offerors and contracting officers how faxed proposals, revisions, modifications, and withdrawals are handled when a solicitation allows facsimile submissions. It defines what counts as a facsimile proposal, states that faxed proposals may be submitted in response to the solicitation, and makes clear that faxed submissions are subject to the same rules as paper proposals. The provision also requires the solicitation to identify the receiving fax number, and it establishes a special procedure if any part of a faxed proposal is unreadable to the point that the Government cannot determine whether the proposal meets the solicitation’s essential requirements. In that case, the contracting officer must notify the offeror, allow resubmission, and set the resubmission method and deadline after consulting with the offeror, while preserving the original receipt date and time for timeliness purposes if the offeror complies. Finally, the provision reserves the Government’s right to make award based solely on the facsimile proposal and allows the contracting officer to require the apparently successful offeror to promptly provide the complete original signed proposal. In practice, this provision is about accepting fax as a valid submission method while protecting the integrity of the competition, timeliness rules, and the Government’s ability to verify the final signed offer.

Place of Performance.

FAR 52.215-6, Place of Performance, is a solicitation provision used to identify whether the offeror or respondent expects to perform contract work at one or more plants or facilities located at an address different from the address shown in the proposal or response. It requires the offeror or respondent to make a clear election between “intends” and “does not intend,” and, if the answer is “intends,” to provide the street address, city, state, county, and ZIP code of each such place of performance. It also requires the name and address of the owner and operator of the plant or facility when that owner/operator is someone other than the offeror or respondent. The provision exists to give the Government visibility into where contract performance will occur, which can matter for responsibility determinations, evaluation, subcontracting or facility-related considerations, site access, security, labor, socioeconomic, and administrative planning. In practice, it helps the contracting officer understand whether the contractor will perform at off-site locations and whether those locations are controlled by the offeror or by another entity. Because it is a representation made in the offer, inaccurate or incomplete responses can create proposal evaluation issues, post-award performance complications, or potential misrepresentation concerns.

Order of Precedence-Uniform Contract Format.

FAR 52.215-8, Order of Precedence—Uniform Contract Format, tells the reader how to resolve conflicts when different parts of a solicitation or contract say different things. It applies to documents prepared using the Uniform Contract Format and establishes a fixed hierarchy among the Schedule (excluding the specifications), representations and other instructions, contract clauses, other documents/exhibits/attachments, and the specifications. Its purpose is to prevent ambiguity and litigation over which provision controls when terms appear inconsistent across sections of the solicitation or contract. In practice, this clause is a tie-breaker: if a requirement in the specifications conflicts with a clause, the clause controls; if instructions conflict with the Schedule, the Schedule controls, and so on down the list. This matters for both offer preparation and contract administration because contractors must price and perform to the controlling text, while contracting officers and acquisition teams must draft documents carefully to avoid unintended conflicts. The clause does not eliminate the need to read the whole solicitation or contract together, but it provides a clear rule for resolving inconsistencies when they cannot be reconciled.

Changes or Additions to Make-or-Buy Program.

FAR 52.215-9, Changes or Additions to Make-or-Buy Program, governs how a contractor may change a contractually incorporated make-or-buy program and how deferred items may later be added to that program. It requires the contractor to follow the approved make-or-buy plan, give the contracting officer advance written notice of proposed changes, and submit enough justification for the government to evaluate the request. It also covers additions for items that were deferred during negotiation, requiring notice and justification at the earliest possible time. The clause makes clear that no change or addition becomes effective until the contracting officer gives written approval. The alternates add a special rule for contracts using incentive pricing arrangements: if the contractor wants to reverse a designated make-or-buy decision, it must support the request with certified cost or pricing data when required and then negotiate an equitable reduction in price, cost, and fee as applicable. In practice, this clause protects the government’s pricing and performance assumptions while giving contractors a controlled process to seek manufacturing or sourcing changes when business conditions change.

Price Reduction for Defective Certified Cost or Pricing Data.

FAR 52.215-10, Price Reduction for Defective Certified Cost or Pricing Data, is the Government’s remedy clause for situations where a negotiated contract price or reimbursable cost was increased because the contractor, a subcontractor, or a prospective subcontractor provided certified cost or pricing data that were not complete, accurate, and current, or otherwise provided inaccurate data. It applies when the Government later discovers that defective data affected the negotiated price, profit or fee, or reimbursable costs, and it requires the contract price to be reduced accordingly and the contract modified to reflect the correction. The clause also addresses defective data from prospective subcontractors, limits the reduction in certain cases to the difference between the estimated and actual subcontract cost plus markup, and allows a contractor to seek an offset for qualifying data that was available but not submitted before the certification date. It further bars several common defenses, such as claims that the contractor was a sole source, that the Government should have known the data were defective, or that the contract was based on a total-cost agreement rather than item-by-item pricing. Finally, if the Government has already paid the inflated amount, the clause requires repayment with daily compounded interest and, in cases of knowing submission of defective certified cost or pricing data, a penalty equal to the overpayment. In practice, this clause is a powerful post-award price adjustment and recovery tool that creates strong incentives for accurate, current, and complete pricing data throughout proposal preparation, subcontract pricing, and certification.

Price Reduction for Defective Certified Cost or Pricing Data-Modifications.

FAR 52.215-11 is the contract clause that lets the Government reduce a contract price when a modification was priced using defective certified cost or pricing data. It applies only to certain contract modifications that are expected to exceed the certified cost or pricing data threshold on the date the modification is signed, unless an exception in FAR 15.403-1(b) applies. The clause covers when it becomes operative, what counts as defective data, how price or cost reductions are calculated, special limits for defective data from a prospective subcontractor that never receives the subcontract, what defenses the contractor may not raise, when offsets may be allowed, and when the contractor must pay interest and a penalty on overpayments. In practice, this clause protects the Government from paying too much because a contractor, subcontractor, or prospective subcontractor submitted incomplete, inaccurate, or noncurrent data during pricing of a modification. It also creates strong incentives for contractors to validate their data, flow the requirement down to subcontractors, and correct known errors before certification. For contracting officers, the clause is a post-award remedy and enforcement tool that can be used to adjust the contract and recover overpayments when defective data affected the negotiated price.

Subcontractor Certified Cost or Pricing Data.

FAR 52.215-12, Subcontractor Certified Cost or Pricing Data, tells prime contractors when and how to flow down the certified cost or pricing data requirement to subcontractors. It covers the timing trigger for obtaining subcontractor data before award or before a pricing adjustment on a subcontract modification, the content of the data package under FAR 15.408 Table 15-2, the requirement to obtain a subcontractor certification that the data are accurate, complete, and current, and the mandatory flowdown of either this clause or FAR 52.215-13 into covered subcontracts. It also addresses the exception for situations where an exception under FAR 15.403-1(b) applies, and it explains how inflation-adjusted thresholds under FAR 1.109 affect the applicable dollar threshold over the life of the contract. The Alternate I version updates the rule for certain subcontracts awarded before or on/after July 1, 2018, with different threshold amounts and a different trigger structure for modifications. In practice, this clause is a key compliance control: it ensures the Government can rely on certified cost or pricing data at the subcontract level when required, and it places the burden on the prime contractor to police subcontractor pricing submissions and certifications.

Subcontractor Certified Cost or Pricing Data-Modifications.

FAR 52.215-13, Subcontractor Certified Cost or Pricing Data—Modifications, tells contractors when they must flow down certified cost or pricing data requirements to subcontractors for both new subcontracts and subcontract modifications. It covers the threshold trigger for when the clause applies, the contractor’s duty to obtain certified cost or pricing data from the subcontractor, the content of that data under FAR Table 15-2, the subcontractor’s certification that the data are accurate, complete, and current, and the mandatory flowdown of the clause into covered subcontracts. The clause also addresses how inflation-adjusted thresholds under FAR 1.109 affect applicability over the life of the contract, and Alternate I adds special rules for subcontract modifications based on whether the subcontract was awarded before or after July 1, 2018, including different dollar thresholds and a special flowdown threshold. In practice, this clause is a pricing-control and audit-support mechanism: it helps the prime contractor support its own pricing submissions to the Government by ensuring that lower-tier subcontract pricing is backed by certified data when required. It matters because failure to obtain the required data or certification can expose the contractor to defective pricing risk, pricing disallowance, and contract administration problems.

Integrity of Unit Prices.

FAR 52.215-14, Integrity of Unit Prices, is a pricing integrity clause used in negotiated procurements for supplies. It addresses how offerors must distribute costs across contract line items so that unit prices reflect the actual base cost of the items, such as manufacturing or acquisition cost, rather than being artificially shifted or averaged in a way that distorts pricing. The clause also allows the Contracting Officer to ask the offeror or contractor to identify supplies it will not manufacture or to which it will not contribute significant value, which helps the Government evaluate pricing realism and detect potential pricing manipulation. In addition, the clause requires flowdown of the substance of the clause to most subcontracts, with specific exceptions for simplified acquisitions, construction and architect-engineer services, utility services, services without supply requirements, commercial products and commercial services, and petroleum products. The clause explicitly states that it does not create a new requirement to submit certified cost or pricing data beyond what is otherwise required by law or regulation. In practice, this clause is meant to protect the Government from misleading unit pricing, support fair price analysis, and improve transparency in supply pricing and subcontract pricing structures.

Pension Adjustments and Asset Reversions.

FAR 52.215-15, Pension Adjustments and Asset Reversions, addresses what happens when a contractor terminates a defined-benefit pension plan, curtails pension benefits, closes a segment, or otherwise recovers pension plan assets. The clause requires prompt written notice to the contracting officer when the contractor determines it will terminate a defined-benefit plan or recapture pension assets, and it establishes how any resulting pension adjustment is measured, assigned, and allocated under the Cost Accounting Standards (CAS). It distinguishes between contracts and subcontracts subject to full CAS coverage and those not subject to full CAS coverage, while still tying the adjustment to the CAS pension cost allocation rules. The clause also covers situations where pension assets revert to the contractor or are constructively received for any reason, giving the Government the option to require a refund or credit for its equitable share of the gross amount withdrawn. Finally, it requires flowdown of the clause to applicable subcontracts. In practice, this clause protects the Government from paying pension costs that are later recovered by the contractor and ensures that pension-related cost adjustments are handled consistently across covered contracts and subcontracts.

Facilities Capital Cost of Money.

FAR 52.215-16 is a solicitation provision about facilities capital cost of money, often abbreviated FCCM. It tells offerors that FCCM may be treated as an allowable cost on the resulting contract only if the allowability requirements in FAR 31.205-10(b) are satisfied, and it highlights one of those requirements: the prospective contractor must actually propose FCCM in its offer. The provision also explains the consequence of not proposing the cost — the resulting contract will include the clause Waiver of Facilities Capital Cost of Money. In practical terms, this provision matters when a contractor wants to recover an imputed cost for the use of capital tied up in facilities, rather than only direct depreciation or other facility-related costs. It is important because the decision to propose or waive FCCM affects pricing, cost realism, and later contract administration, and it must be handled at the proposal stage rather than after award. This provision is short, but it connects the solicitation, the cost principles, and the final contract terms in a way that can materially affect the contractor’s allowable costs.

Waiver of Facilities Capital Cost of Money.

FAR 52.215-17, Waiver of Facilities Capital Cost of Money, is a very short clause with a very specific purpose: it makes clear that if the contractor did not include facilities capital cost of money in its proposed cost for the contract, then that cost is waived and cannot later be charged to the Government. The clause addresses only one topic—facilities capital cost of money—and its treatment as an unallowable cost under the contract when it was not proposed. In practice, this clause protects the Government from paying for a cost element that was not part of the contractor’s original proposal and prevents post-award attempts to add that cost into incurred cost submissions, billing, or pricing adjustments. It is a cost-accounting and pricing control clause, not a performance clause, and it matters most in cost-reimbursement, time-and-materials, or other negotiated acquisitions where cost buildup and allowability are important. The clause also reinforces the principle that proposal content can determine whether certain cost elements are recoverable later under the contract.

Reversion or Adjustment of Plans for Postretirement Benefits (PRB) Other Than Pensions.

FAR 52.215-18 addresses what happens when a contractor terminates, reduces, or otherwise changes a postretirement benefits (PRB) plan other than pensions and when PRB plan assets revert to, inure to, or are constructively received by the contractor. Its purpose is to protect the Government’s share of any previously reimbursed PRB costs so the contractor does not retain amounts that should offset contract costs. The clause requires prompt written notice to the Contracting Officer when the contractor decides to terminate or reduce PRB benefits, and it ties recovery of any Government share to the cost principle at FAR 31.205-6(o)(5). It also identifies acceptable recovery methods—such as cost reduction, amortization of the credit with interest, cash refund, or another agreed method—and gives the Contracting Officer authority to choose a method if the parties cannot agree through good-faith negotiations. Finally, it requires flowdown of the clause’s substance to applicable subcontracts, making the rule relevant not only to prime contractors but also to lower-tier arrangements where PRB cost issues may arise. In practice, this clause is about timely disclosure, equitable cost adjustment, and ensuring the Government receives credit when PRB funding changes create a contractor benefit.

Notification of Ownership Changes.

FAR 52.215-19, Notification of Ownership Changes, requires contractors to promptly inform the Administrative Contracting Officer (ACO) when an ownership change has occurred or is certain to occur if that change could affect the valuation of capitalized assets or cause other cost changes. The clause also requires notice when asset valuations or other costs have changed, or are certain to change, because of the ownership change. Beyond notice, it imposes recordkeeping and accounting duties: maintaining current, accurate, and complete inventory records; allowing the ACO or a designated representative access to those records; correctly identifying individual and grouped assets, capitalized values, accumulated depreciation or amortization, and remaining useful lives before and after each ownership change; and preserving depreciation and amortization schedules based on pre-change asset records. Finally, the clause requires flowdown to applicable subcontracts under FAR 15.408(k). In practice, this clause is about protecting the Government’s ability to evaluate cost impacts, preserve auditability of asset accounting, and avoid distortions in pricing, reimbursement, or cost allowability after a change in corporate control.

Requirements for Certified Cost or Pricing Data and Data Other Than Certified Cost or Pricing Data.

FAR 52.215-20 is the solicitation provision that tells offerors when they must submit certified cost or pricing data, when they may instead request an exception, and what supporting information must accompany either path. It covers the exceptions from certified cost or pricing data, including exceptions based on law or regulation, commercial products and commercial services, and items priced by catalog or market pricing; it also addresses the Government’s right to examine records to verify an exception request and price reasonableness. If no exception is granted, the provision requires submission of certified cost or pricing data, data other than certified cost or pricing data, supporting attachments, and a Certificate of Current Cost or Pricing Data before award. The clause also includes alternate versions that change the required format, add distribution requirements to the Administrative Contracting Officer and Contract Auditor, require electronic submission of the cost portion, or replace the clause entirely when certified cost or pricing data are not required. In practice, this provision is central to price analysis in negotiated procurements because it determines what data the Government can demand, what the contractor must disclose, and how the contracting officer will establish that the price is fair and reasonable.

Requirements for Certified Cost or Pricing Data and Data Other Than Certified Cost or Pricing Data-Modifications.

FAR 52.215-21 governs what a contractor must provide when a contract modification may require certified cost or pricing data, and when the contractor may instead seek an exception from that requirement. It covers the threshold for applying the rule, the process for requesting an exception, the specific information needed to support exceptions based on law or regulation, and the special rules for modifications to commercial products and commercial services contracts or subcontracts. It also addresses the Government’s right to examine directly pertinent records to verify an exception request and assess price reasonableness, while limiting access for catalog-, market-, or law-based pricing to information relevant to those pricing methods. If no exception is granted, the clause requires submission of certified cost or pricing data, data other than certified cost or pricing data, supporting attachments in the format prescribed by FAR 15.408, and a Certificate of Current Cost or Pricing Data before award, except for unpriced actions. In practice, this clause is a key pricing compliance tool for modifications that may increase contract price above the Truthful Cost or Pricing Data threshold, and it helps the contracting officer decide whether the Government can rely on an exception or must obtain full pricing support.

Limitations on Pass-Through Charges-Identification of Subcontract Effort.

FAR 52.215-22 is a solicitation provision used to collect information about subcontracting effort so the Government can evaluate whether an offer includes excessive pass-through charges and whether the prime contractor or higher-tier subcontractors are contributing meaningful added value. It works together with FAR 52.215-23, which defines key terms such as added value, excessive pass-through charge, subcontract, and subcontractor, and it requires offerors to identify the total cost of work performed by the offeror and by each subcontractor. The provision also triggers additional disclosure when the offeror plans to subcontract more than 70 percent of the total cost of work, or when a proposed subcontractor plans to subcontract more than 70 percent of its own subcontracted work to lower-tier firms. In those cases, the offeror must disclose the indirect costs and profit/fee associated with the subcontracted work and explain the added value provided by the offeror or subcontractor. In practice, this provision is intended to help contracting officers assess whether the proposed contracting structure is efficient and whether the prime is doing enough substantive work to justify its role and markup. It is especially important on large, complex, or heavily subcontracted acquisitions where the Government wants visibility into who is actually performing the work and what value each tier adds.

Limitations on Pass-Through Charges.

FAR 52.215-23, Limitations on Pass-Through Charges, is the clause that limits the Government’s exposure to charges added by contractors or subcontractors when they do little or no value-added work. It covers the definitions of added value, excessive pass-through charge, no or negligible value, subcontract, and subcontractor; the Government’s general rule that it will not pay excessive pass-through charges; the contractor’s reporting duty when subcontract effort exceeds 70 percent of total contract or subcontract cost; the remedy if excessive pass-through charges are found; the Government’s right to examine and audit records; and the requirement to flow the clause down into certain subcontracts. It also includes an alternate version used in some DoD procurements that changes the general rule when the contracting officer has already determined there will be no excessive pass-through charges if the contractor performs the disclosed value-added functions. In practice, this clause is aimed at preventing “middleman” charges where a prime or higher-tier subcontractor adds little beyond subcontract management, while still allowing reasonable compensation for legitimate management and oversight work. It matters because it can affect pricing, subcontracting strategy, recordkeeping, audit exposure, and whether a contractor must notify the contracting officer after award if its subcontracting mix changes significantly.
