    FAR 52.228-3Workers’ Compensation Insurance (Defense Base Act).

    Plain-English Summary

    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.

    Key Rules

    Secure DBA coverage first

    Before starting performance, the contractor must establish provisions to pay disability, medical, and death benefits for covered employees. This is done by purchasing workers’ compensation insurance or qualifying as a self-insurer under the Longshore and Harbor Workers’ Compensation Act as extended by the Defense Base Act.

    Maintain coverage through completion

    The contractor must keep DBA benefit provisions in place for the entire period of contract performance. Coverage cannot lapse while covered work is ongoing.

    Report injuries and deaths promptly

    Within 10 days of an injury or death, or within 10 days after learning of it, the contractor must submit Form LS-202 to the Department of Labor. This is the required first report of injury or occupational illness.

    Pay compensation on time

    The contractor must pay disability or death compensation within the time limits required by the Longshore and Harbor Workers’ Compensation Act and its implementing regulations. Late payment can trigger statutory consequences.

    Provide required medical care

    The contractor must furnish medical treatment as required by the Longshore and Harbor Workers’ Compensation Act and DOL regulations. Medical benefits are part of the DBA protection, not optional extras.

    File controversion and payment notices

    If the contractor disputes a claim, it must file Form LS-207. When it makes the first compensation payment without an award, it must file Form LS-206, and when payments are suspended or finally ended, it must file Form LS-208.

    Follow all DBA and DOL rules

    The contractor must comply with all other provisions of the Longshore and Harbor Workers’ Compensation Act as extended by the DBA and with DOL regulations at 20 CFR Parts 701 through 704.

    Flow down to covered subcontracts

    The contractor must insert the substance of the clause, including paragraph (c), in all subcontracts to which the Defense Base Act applies. This ensures subcontractor employees receive the same statutory protections.

    Responsibilities

    Contracting Officer

    Include this clause when prescribed by FAR 28.309(a) and ensure the contract reflects DBA coverage requirements for the work. The contracting officer should also understand that the clause creates mandatory contractor obligations and subcontract flowdown requirements.

    Contractor

    Obtain and maintain DBA insurance or self-insurance before performance begins; pay required disability, medical, and death benefits; file LS-202, LS-206, LS-207, and LS-208 as required; comply with the LHWCA and DOL regulations; and flow the clause down to covered subcontracts.

    Subcontractor

    When the DBA applies to the subcontract, comply with the flowed-down clause, maintain required coverage for covered employees, and meet the same reporting, payment, and medical-care obligations for its workforce.

    Department of Labor

    Administer the DBA/LHWCA claims and reporting framework, receive required forms, and enforce the statutory and regulatory requirements governing compensation, medical care, and claim controversion.

    Covered Employee / Eligible Survivor

    Provide injury, illness, or death information needed to support claims and benefit administration, and pursue benefits under the DBA/LHWCA framework when entitled.

    Practical Implications

    1

    DBA coverage is often a prerequisite to starting overseas or otherwise covered work, so contractors should confirm insurance or self-insurance arrangements before mobilization.

    2

    The 10-day LS-202 reporting deadline is easy to miss, especially when injuries are reported late internally; contractors need a clear incident-reporting process.

    3

    Claims administration is form-driven, so missing LS-206, LS-207, or LS-208 filings can create compliance problems even when benefits are being paid.

    4

    Subcontract flowdown is not optional for covered work; prime contractors should verify that subcontract language and insurance arrangements match the DBA requirement.

    5

    Because the clause incorporates the LHWCA and DOL regulations by reference, contractors must look beyond the FAR text and manage the underlying statutory and regulatory deadlines, benefit rules, and notice requirements.
