FAR 52.228—[Reserved]

Bid Guarantee.

FAR 52.228-1, Bid Guarantee, addresses when a bid guarantee is required, what forms it may take, how much it must be, when it must be submitted, when the Government returns it, and what happens if the apparent successful bidder does not follow through after award. In practical terms, this provision protects the Government against the risk that a low bidder will refuse to execute the contract or provide required performance and payment bonds after being selected for award. It also gives contracting officers a basis to reject a bid that lacks a proper guarantee, although the clause uses permissive language (“may be cause for rejection”) rather than automatic rejection in every case. The clause covers acceptable guarantee instruments such as bid bonds, certified checks, cashier’s checks, postal money orders, irrevocable letters of credit, and certain Treasury instruments, as well as the timing for return of guarantees to unsuccessful and successful bidders. It further explains the bidder’s liability if default occurs after award and the Government must reprocure at a higher price, allowing the bid guarantee to offset the excess reprocurement cost. For contractors, the clause is a strict compliance item tied to bid responsiveness and post-award obligations; for contracting officers, it is a risk-management tool that must be applied consistently with the solicitation and applicable bonding requirements.

Additional Bond Security.

FAR 52.228-2, Additional Bond Security, tells the contractor when it must provide extra or replacement security to keep the Government and labor and material suppliers protected during contract performance. The clause covers four specific triggers: when a surety or other issuing financial institution becomes unacceptable to the Government, when a surety fails to provide required financial reports, when a contract price increase makes the existing bond penal sum too low in the Contracting Officer’s judgment, and when an irrevocable letter of credit (ILC) will expire before the required security period ends. It also gives the Contracting Officer a direct remedy for ILCs: if the contractor does not provide an acceptable extension, replacement, or substitute at least 30 days before expiration, the Government may immediately draw on the ILC. In practice, this clause is about maintaining continuous, adequate financial protection as the contract changes or as the financial condition of the security provider changes. It matters because bond or ILC deficiencies can expose the Government and subcontractors/suppliers to payment risk and can create performance and closeout problems if not corrected quickly.

Workers’ Compensation Insurance (Defense Base Act).

FAR 52.228-3 implements the Defense Base Act (DBA) workers’ compensation framework for covered overseas and related federal contract work. It tells contractors how to secure and maintain DBA coverage, which employees are covered, and what benefits must be provided for disability, medical care, and death. It also sets out the required Department of Labor reporting and claims forms: LS-202 for injury or death reporting, LS-207 for controversion, LS-206 for payment without award, and LS-208 for final payment or suspension. The clause ties contractor performance to the Longshore and Harbor Workers’ Compensation Act as extended by the DBA, including payment timing rules and medical-care obligations, and it requires compliance with the applicable DOL regulations in 20 CFR Parts 701 through 704. It also requires flowdown of the clause to covered subcontracts. In practice, this clause is critical because DBA coverage is often mandatory for overseas federal work, and failure to secure coverage or file the required notices can create serious legal, financial, and performance risks for both contractors and subcontractors.

Workers’ Compensation and War-Hazard Insurance Overseas.

FAR 52.228-4 addresses insurance and benefit protection for contractor employees working overseas when the Secretary of Labor has waived application of the Defense Base Act (DBA) and, in turn, the War Hazards Compensation Act (WHCA). The clause has two separate but related parts: paragraph (a) covers workers’ compensation insurance or equivalent coverage for employees who would otherwise be covered by the DBA but for a waiver, and paragraph (b) covers war-hazard benefits for employees who would otherwise be covered by the WHCA but for a waiver. It also requires flowdown of these protections to affected subcontractors, unless the prime contractor elects to assume direct liability for subcontractor employees under the war-hazard portion. In practice, this clause ensures that employees working overseas do not lose basic injury/death protection simply because a statutory waiver removes the normal DBA/WHCA framework. It matters because it shifts real compliance obligations onto the contractor before performance begins, requires continuous coverage through contract completion, and can affect subcontract drafting, pricing, reimbursement, and risk allocation.

Insurance-Work on a Government Installation.

FAR 52.228-5, Insurance—Work on a Government Installation, sets the basic insurance framework for contractors performing work on federal property. It addresses four main topics: the contractor’s duty to obtain and maintain required insurance at its own expense; the requirement to notify the contracting officer before starting work that coverage is in place; the need for insurance policies to include an endorsement limiting cancellation or material-change effectiveness so the Government has advance notice; and the flowdown requirement to subcontractors performing work on a Government installation. In practice, this clause is used to protect the Government from uninsured or underinsured losses, especially where contractor activities occur on federal premises and could create liability exposure to the United States. It also gives the contracting officer a way to verify coverage and react if a policy is canceled or materially changed. For contractors, the clause means insurance compliance is not optional or merely internal risk management—it is a contract performance requirement tied to start of work and subcontract administration.

[Reserved]

Insurance-Liability to Third Persons.

FAR 52.228-7, Insurance—Liability to Third Persons, sets the contractor’s insurance and risk-allocation obligations for contracts where the Government wants protection against third-party claims arising from contract performance. It covers the types of insurance the contractor must carry, including workers’ compensation, employer’s liability, comprehensive general liability, and comprehensive automobile liability, as well as any additional insurance the contracting officer requires. It also allows approved self-insurance for qualified contractors, gives the contracting officer control over the form, amount, period, and insurer approval, and requires disclosure and approval of other insurance maintained in connection with the contract when reimbursement is sought. The clause then explains when the Government will reimburse insurance costs and certain third-party liabilities, including the requirement that such liabilities arise from contract performance, be supported by final judgments or approved settlements, and involve property damage or death/bodily injury not otherwise excluded. It also addresses the availability of appropriated funds, exclusions for liabilities already assigned elsewhere in the contract, failures to insure, and willful misconduct or lack of good faith by senior management. Finally, it requires prompt notice to the contracting officer when claims arise, cooperation with Government and insurer counsel, and, in uninsured or underinsured claims, Government control or participation in settlement or defense. In practice, this clause is a major risk-management and reimbursement provision: it tells contractors what coverage they must maintain, what costs may be recoverable, when the Government can step into a claim, and where reimbursement stops.

Liability and Insurance-Leased Motor Vehicles.

FAR 52.228-8, Liability and Insurance—Leased Motor Vehicles, allocates risk when the Government leases motor vehicles for contract performance. It addresses who bears responsibility for damage to leased vehicles, loss or injury to third parties, contractor liability for negligent acts, required insurance coverage and minimum limits, notice to the contracting officer before work begins, required policy endorsements for cancellation or material change, the prohibition on insurer subrogation against the Government, and pricing rules that keep the contractor from charging the Government for risks the Government itself must bear. In practice, the clause is meant to prevent disputes over vehicle-related losses by clearly separating Government-responsible losses from contractor-caused losses and by ensuring the contractor carries insurance for its own liability. It is especially important where contractors operate leased vehicles on or off Government property, because motor vehicle incidents can create property damage, bodily injury, and tort claims quickly. The clause also ties directly to the Federal Tort Claims Act, so the Government’s exposure depends on whether the claim is one for which the United States would be liable under that statute. For contracting officers, the clause is a risk-allocation and compliance tool; for contractors, it is a mandatory insurance and indemnity obligation that must be in place before performance starts.

Cargo Insurance.

FAR 52.228-9, Cargo Insurance, is a contract clause used when the Government wants the contractor to carry specific cargo insurance for property being transported under the contract. It addresses the contractor’s duty to obtain and maintain insurance at its own expense, the required dollar amounts per vehicle and for the shipment as a whole, and the need for the insurance to be written by companies acceptable to the contracting agency. The clause also requires the contractor to provide proof of acceptable coverage before starting performance and to ensure the policy contains mandatory notice provisions for cancellation, reduction in coverage, and renewal. In practice, this clause protects the Government’s property interests during transit by shifting the risk of loss to an insured carrier arrangement and by giving the agency advance warning if coverage changes. It is especially important in transportation, logistics, and shipment contracts where Government-owned or Government-controlled property is exposed to loss, damage, or theft while in transit.

Vehicular and General Public Liability Insurance.

FAR 52.228-10, Vehicular and General Public Liability Insurance, is a solicitation and contract clause used in transportation and transportation-related service contracts when the contracting officer determines that insurance required by law is not enough to protect the Government’s interests. The clause addresses four main subjects: when the clause may be inserted, the contractor’s duty to maintain vehicular liability insurance, the contractor’s duty to maintain general public liability insurance, and the contractor’s separate duty to carry workers’ compensation and other legally required insurance for its own employees and agents. It requires the contracting officer to set specific dollar limits for bodily injury and property damage coverage in the contract, making the insurance requirement tailored to the risk of the work. In practice, the clause shifts the cost and responsibility for maintaining adequate third-party liability coverage to the contractor for the life of the contract. It is especially important where vehicles, public exposure, or transportation activities create a meaningful risk of injury or property damage beyond what mandatory state or local insurance laws already require. The clause does not itself define all insurance terms or replace applicable law; instead, it supplements legal minimums with contract-specific coverage levels determined by the contracting officer.

Individual Surety—Pledge of Assets.

FAR 52.228-11, Individual Surety—Pledge of Assets, governs what happens when a contractor uses a person rather than a corporate surety to back a performance bond or payment bond. It requires the contractor to obtain a qualifying pledge of assets from each individual surety and to collect Standard Form 28, Affidavit of Individual Surety, so the Government can evaluate the surety’s eligibility and the adequacy of the pledged security under FAR 28.203-1. The clause also explains how long the pledged assets must remain in place, which varies depending on whether the contract is a construction contract covered by the Miller Act, a contract subject to alternative payment protection, or another type of contract. It further addresses when the contracting officer may release part of the security interest for a performance bond after substantial performance, and when pledged assets supporting a payment bond may be released to a subcontractor or supplier based on a court judgment or sworn claim with surety authorization. Finally, it allows the contracting officer to approve substitution of an individual surety after award, provided the contractor meets the clause’s requirements within the time set by the contracting officer. In practice, this clause is about protecting the Government and unpaid subcontractors or suppliers by ensuring that individual surety arrangements are real, properly documented, and maintained for the required period.

Prospective Subcontractor Requests for Bonds.

FAR 52.228-12, Prospective Subcontractor Requests for Bonds, addresses a narrow but important transparency requirement in federal construction contracting: when a payment bond has been furnished to the Government for the contract, the prime contractor must provide a copy of that bond to a prospective subcontractor or supplier who asks for it. The clause implements statutory policy intended to help lower-tier firms decide whether to extend labor or materials on credit by letting them verify that a payment bond exists. It applies only when the contract is one for which a payment bond has been furnished under the Miller Act bond framework in 40 U.S.C. chapter 31, subchapter III, and it is triggered by a request from a prospective subcontractor or supplier offering to furnish labor or material for the contract’s performance. In practice, the clause reduces uncertainty for subcontractors and suppliers, supports payment protection on bonded projects, and creates a clear administrative duty for the prime contractor to respond promptly. It does not itself create the bond requirement; rather, it governs access to the bond information once the bond is already in place. The clause is especially relevant on construction and other covered projects where payment bond rights and downstream credit decisions matter.

Alternative Payment Protections.

FAR 52.228-13, Alternative Payment Protections, tells the contractor how to satisfy the Government’s requirement for payment security when a contract calls for a protection other than a standard payment bond. This clause covers the type of protection the contractor must submit, the required amount of that protection, the deadline for submission after award, the period the protection must cover, the Government’s authority to reach protected funds when a supplier of labor or material alleges nonpayment, and a special rule for tripartite escrow agreements. In practice, the clause is used to ensure that subcontractors, suppliers, and labor providers have a financial backstop if the prime contractor does not pay them. It gives the contracting officer a mechanism to protect those lower-tier parties while still allowing flexibility in the form of security used. The clause is especially important on contracts where the Government wants payment assurance but the parties are using an escrow arrangement or another alternative instead of a conventional bond.

Irrevocable Letter of Credit.

FAR 52.228-14, Irrevocable Letter of Credit, sets the government’s rules for using an irrevocable letter of credit (ILC) instead of a bid bond or as security in place of corporate or individual sureties for performance and payment bonds. It defines what an ILC is, requires that it be truly irrevocable and payable on written demand, and prescribes the exact formats for the issuing bank’s letter and any confirming letter. The clause also establishes when an ILC may be used as a bid guarantee, how long it must remain in effect, and how automatic annual renewal works unless the bank gives timely non-renewal notice. It further limits who may issue or confirm an ILC by requiring federally insured, investment-grade financial institutions, and adds special confirmation requirements for larger ILCs. In practice, this clause protects the Government by ensuring that the financial backing behind a bid or bond substitute is reliable, collectible, and available for the full period of required coverage. Contractors must coordinate closely with their financial institution and the contracting officer to make sure the ILC language, expiration dates, renewal terms, and credit ratings all satisfy the clause before award or bond substitution is accepted.

Performance and Payment Bonds-Construction.

FAR 52.228-15, Performance and Payment Bonds-Construction, is the standard construction bonding clause used to protect the Government and subcontractors on covered construction contracts. It addresses the definition of "original contract price," when performance and payment bonds are required, the required penal amounts for each bond, the Government’s ability to require additional bond protection if the contract price increases, the deadline for furnishing executed bonds, acceptable forms of surety or other security, and the rule governing waivers of subcontractor rights to sue on the payment bond. In practice, this clause is a core risk-allocation tool: it helps ensure the contractor will complete the work, and that subcontractors and suppliers will be paid if the prime contractor fails to pay them. For contracting officers, it is a compliance and administration checkpoint before work starts and whenever the contract price changes. For contractors, it creates a mandatory pre-performance obligation to secure and deliver acceptable bonds, and it can require additional bonding later if the contract is modified upward. For subcontractors and suppliers, it preserves statutory payment-bond protections and limits the enforceability of any waiver of those rights.

Performance and Payment Bonds-Other Than Construction.

FAR 52.228-16 addresses performance and payment bonds for non-construction contracts, including when the clause is used, how the required bond amounts are calculated, when the contractor must submit the bonds, and what happens if the contract price increases after award. It defines “original contract price” for fixed-price, requirements, and indefinite-quantity contracts, and it explains that options are generally excluded unless exercised at award. The clause requires the contractor to furnish a performance bond and, in the basic clause, a payment bond, both in specified percentages of the original contract price, using the prescribed Standard Forms 1418 and 1416. It also covers acceptable bond/security forms, including corporate sureties listed in Treasury Circular 570, individual sureties, and certain alternative securities. In practice, this clause protects the Government against contractor default and protects subcontractors and suppliers against nonpayment, while giving the Government a mechanism to demand additional bond protection if the contract value grows. Alternate I modifies the basic clause by removing the payment bond requirement and limiting the Government’s ability to require additional protection to performance bond protection only.

Individual Surety—Pledge of Assets (Bid Guarantee).

FAR 52.228-17 is a solicitation provision used when an offeror relies on an individual surety to support a bid guarantee. It tells offerors what they must obtain from each individual surety: a pledge of assets that satisfies FAR 28.203-1’s eligibility, valuation, and security standards, plus Standard Form 28, Affidavit of Individual Surety. It also explains when those materials must be submitted—within the timeframe set by FAR 52.228-1, Bid Guarantee, or another deadline established by the contracting officer. Finally, it gives the contracting officer authority to release the security interest in the surety’s assets if there is evidence that the bid supported by the surety will not result in award. In practice, this provision protects the Government by ensuring that an individual surety’s backing is real, properly documented, and legally enforceable before the Government relies on it to secure a bid.
