FAR 52.242—[Reserved]

Notice of Intent to Disallow Costs.

FAR 52.242-1, Notice of Intent to Disallow Costs, gives the Government a formal way to tell a contractor that certain incurred or planned costs appear unallowable under the contract and may be disallowed. The clause applies when a cost-reimbursement contract, a fixed-price incentive contract, or a contract with price redetermination is contemplated, and it is inserted as prescribed by FAR 42.802. It covers the contracting officer’s authority to issue a written notice of intent to disallow specified costs, the contractor’s right to respond in writing with justification, the 60-day response and decision timelines, and the Government’s reservation of rights even if no notice is issued. In practice, the clause is a procedural safeguard: it helps the Government identify and challenge questionable costs early, while giving the contractor an opportunity to explain, support, or correct the cost treatment before a final disallowance decision is made. It does not itself create the underlying allowability rules; those come from the contract terms and applicable cost principles, but it provides the process for raising and resolving disputes about those costs.

Production Progress Reports.

FAR 52.242-2, Production Progress Reports, is a contract clause used when the Government needs periodic reporting on the contractor’s production status. It addresses two main topics: the contractor’s duty to prepare and submit the production progress reports identified in the contract Schedule, and the Contracting Officer’s authority to withhold payment if a required report is delayed. In practice, this clause gives the Government a simple oversight tool for monitoring schedule performance, identifying production problems early, and encouraging timely reporting. It matters most in supply or production contracts where visibility into manufacturing progress, delivery risk, or bottlenecks is important. The clause is not a general reporting requirement for all contracts; it applies only when the contract specifically calls for these reports in the Schedule. It also creates a financial incentive for compliance by allowing the Contracting Officer to withhold a limited amount from payment during a reporting delay.

Penalties for Unallowable Costs.

FAR 52.242-3, Penalties for Unallowable Costs, tells contractors and contracting officers how the Government handles unallowable costs that appear in certain cost submissions. It defines the term “proposal” for this clause, covering a final indirect cost rate proposal and, when applicable, the final statement of costs under an Incentive Price Revision clause. It then explains that contractors may face penalties if they include unallowable indirect costs, especially costs that are expressly unallowable or costs previously determined to be unallowable for that contractor. The clause also ties the penalties to the statutory framework in 10 U.S.C. 3748 or 41 U.S.C. chapter 43 and the implementing rules in FAR 42.709, including how penalties are calculated, when interest applies, and when the contracting officer may waive a penalty. Finally, it makes clear that a penalty payment is not the same as repaying the underlying unallowable cost, and that penalty determinations are final decisions under the Contract Disputes Act. In practice, this clause is a strong compliance and accounting control mechanism: contractors must screen indirect cost submissions carefully, and contracting officers must identify, assess, and document unallowable costs consistently.

Certification of Final Indirect Costs.

FAR 52.242-4, Certification of Final Indirect Costs, requires contractors to formally certify proposals used to establish or modify final indirect cost rates. The clause addresses who must sign the certification, the exact certification language that must be used, and the consequences of failing to submit a proper signed certificate. In practice, this clause is a key control in the indirect rate settlement process because it places senior management accountability behind the accuracy and allowability of the costs included in the proposal. It is intended to help the Government rely on the contractor’s representation that the proposal excludes expressly unallowable costs and that all included costs comply with the FAR cost principles and any applicable supplements. The clause also gives the Contracting Officer leverage to establish final indirect costs unilaterally if the contractor does not provide the required certification. For contractors, this means final indirect rate proposals must be prepared, reviewed, and signed with the same seriousness as other formal compliance submissions; for contracting officers, it provides a basis to reject incomplete submissions and protect the Government’s interests during rate negotiations.

Payments to Small Business Subcontractors.

FAR 52.242-5, Payments to Small Business Subcontractors, requires prime contractors to give the Contracting Officer prompt written notice when they make a reduced payment, an untimely payment, or fail to make a payment to a small business subcontractor that is otherwise due under the subcontract. The clause defines two key terms—"reduced payment" and "untimely payment"—and ties the notice obligation to situations where the Government has already paid the prime contractor for the supplies or services at issue. It also sets a specific timing rule: the contractor must notify the Contracting Officer no later than 14 days after the subcontractor became entitled to payment and the contractor made a reduced or late payment, or failed to pay and the payment is now late. The notice must include the reasons for the reduced or untimely payment. In practice, this clause is designed to improve transparency, protect small business subcontractors, and give the Government visibility into prime contractor payment performance on subcontracted work that has already been funded by the Government.

Bankruptcy.

FAR 52.242-13, Bankruptcy, requires a contractor to promptly notify the Government if it enters bankruptcy proceedings, whether the filing is voluntary or involuntary. The clause specifies the method of notice, the five-day deadline, the required contents of the notice, and the contracting officer who must receive it. It also requires the contractor to identify the bankruptcy filing date, the court where the petition was filed, and all Government contracts for which final payment has not yet been made, including the relevant contracting offices. In practice, this clause gives the Government early warning that a contractor’s financial distress may affect performance, payment, administration, and risk management across one or more contracts. It also helps the contracting officer coordinate internally and protect the Government’s interests while the bankruptcy case is pending. The obligation continues until final payment under the contract, so the duty to notify does not end merely because the bankruptcy is filed.

Suspension of Work.

FAR 52.242-14, Suspension of Work, is a clause used in fixed-price construction and architect-engineer contracts to address government-caused work stoppages or slowdowns. It gives the Contracting Officer the authority to order the contractor, in writing, to suspend, delay, or interrupt all or part of the work for the Government’s convenience, and it also creates a remedy when an unreasonable suspension, delay, or interruption is caused by the Contracting Officer’s acts or failure to act. The clause covers when the government may direct a suspension, when the contractor may recover increased performance costs (but not profit), how causation is limited by other causes or other contract remedies, and the notice and timing requirements for asserting a claim. In practice, this clause is important because it allocates risk for government-caused delays, protects contractors from uncompensated cost growth caused by unreasonable administrative delay, and requires prompt written notice and documentation to preserve recovery rights. It is a common issue on construction and A-E projects where design approvals, access, funding, site conditions, or other government actions can slow performance.

Stop-Work Order.

FAR 52.242-15, Stop-Work Order, gives the Contracting Officer a formal tool to pause contract performance for a limited time while the Government decides whether to resume the work or end it. This clause covers the authority to issue a written stop-work order, the contractor’s immediate duty to comply and minimize costs, the 90-day stop-work period and any agreed extension, the Government’s obligation to either cancel the order or terminate the affected work, and the contractor’s right to resume work when the stoppage ends. It also addresses equitable adjustments to the delivery schedule, contract price, estimated cost, fee, and other affected terms when the stoppage increases time or cost, as well as the treatment of reasonable stop-work-related costs if the work is later terminated for convenience or default. In practice, the clause is a risk-management and preservation mechanism: it lets the Government halt work quickly without immediately deciding the final disposition of the effort, while protecting the contractor’s right to recover certain impacts if the stop-work order causes additional cost or delay. The alternate version for cost-reimbursement contracts changes the termination reference and broadens the adjustment language to fit that contract type. Contractors and contracting officers should treat the clause as a tightly managed process with strict notice, timing, documentation, and settlement requirements.

Government Delay of Work.

FAR 52.242-17, Government Delay of Work, gives the contractor a limited right to an equitable adjustment when the Government, through the Contracting Officer, delays or interrupts performance in ways that are not authorized by the contract or fails to act when the contract requires action within a stated time, or within a reasonable time if no time is stated. The clause covers both cost and schedule impacts: the contractor may recover increased cost of performance, but the adjustment expressly excludes profit, and the contract must also be modified to reflect any changed delivery dates, performance periods, or other affected terms and conditions. The clause also limits recovery by requiring the contractor to show that the delay was not caused by another source, including the contractor’s own fault or negligence, and that no other contract clause already provides or bars an adjustment for the same event. It further imposes strict notice and claim timing rules, including a 20-day lookback limit for costs incurred before written notice and a requirement to assert the claim in writing, with an amount stated, as soon as practicable after the delay ends and no later than final payment. In practice, this clause is a government-caused delay remedy, but it is narrower than many contractors expect because it is tied to Contracting Officer actions or inaction, excludes profit, and depends heavily on prompt written notice and careful documentation.
