6.6 Bid Protests, Disputes, Appeals & Contract Closeout (FAR Part 33 & 4.8)

Key Takeaways

  • Bid protests (FAR Subpart 33.1) must be filed by interested parties prior to bid opening for pre-award solicitation defects, or within 10 days of knowledge (5 days after required debriefing) for post-award protests to trigger the statutory CICA automatic stay.
  • The Contract Disputes Act (CDA) governs contractor claims, imposing a 6-year statute of limitations from claim accrual and requiring formal certification under FAR 33.207 for contractor claims exceeding $100,000.
  • Contracting Officers must issue a Final Decision (COFD) within 60 days of receiving a certified claim over $100,000, with failure to decide constituting a deemed denial authorizing immediate appeal.
  • Appeals of a COFD must be filed within 90 calendar days to a Board of Contract Appeals (ASBCA or CBCA) or within 1 year (12 months) to the U.S. Court of Federal Claims (COFC).
  • Mandatory contract closeout timelines (FAR 4.804-1) require immediate closeout for simplified acquisitions, 6 months for firm-fixed-price contracts, 36 months for contracts requiring indirect cost rate settlement, and 20 months for all other contracts.

6.6 Bid Protests, Disputes, Appeals & Contract Closeout (FAR Part 33 & 4.8)

The final phase of the federal acquisition lifecycle encompasses legal dispute resolution mechanisms and administrative contract closeout. When disagreements arise regarding solicitation terms, contract awards, or performance claims, federal law prescribes rigid procedural frameworks. Once performance is complete, the Contracting Officer must execute formal closeout actions to de-obligate excess funds and archive contract files.

FAR Part 33 (Protests, Disputes, and Appeals) and FAR Subpart 4.8 (Government Contract Files) establish the statutory deadlines and administrative workflows governing these critical processes.


1. Bid Protest Procedures, Timelines & CICA Stay Mechanics (FAR Subpart 33.1)

A bid protest is a written objection by an interested party to a solicitation, cancellation, or contract award (FAR 33.101).

Interested Party Standing & Protest Forums

  • Interested Party: An actual or prospective offeror whose direct economic interest would be affected by contract award or failure to receive award.
  • Protest Forums: Offerors may file protests with the Procuring Agency, the Government Accountability Office (GAO), or the U.S. Court of Federal Claims (COFC).

Strict Timeliness Rules & The CICA Automatic Stay

Under the Competition in Contracting Act (CICA - 31 U.S.C. 3553), filing a timely protest with GAO triggers a mandatory automatic stay suspending contract award or performance.

Protest ScenarioTimeliness Rule to Trigger CICA Automatic StayGAO Decision Statutory Limit
Pre-Award Protest (Solicitation Defects)Must be filed prior to bid opening or proposal closing date.100 Calendar Days (50 days Express Option)
Post-Award Protest (Award Challenge)Must be filed within 10 calendar days after contract award, OR within 5 calendar days after a required debriefing date, whichever is later.100 Calendar Days (50 days Express Option)

CICA Stay Override: The Head of the Contracting Activity (HCA) may override the automatic stay only by issuing a written finding of urgent and compelling circumstances or best interests of the United States (FAR 33.104).


2. Contract Disputes Act (CDA) & Claim Administration (FAR Subpart 33.2)

The Contract Disputes Act of 1978 (41 U.S.C. 7101-7109) governs claims arising under or relating to executive agency contracts.

Statutory Definition of Claim & 6-Year Statute of Limitations

Under FAR 2.101, a claim is a written demand seeking as a matter of right the payment of money in a sum certain, adjustment of contract terms, or other relief. Under FAR 33.206, all contractor and government claims must be submitted within 6 years after accrual of the claim.

Mandatory Claim Certification Threshold ($100,000)

Under FAR 33.207, contractor claims exceeding $100,000 MUST be accompanied by a formal written certification stating:

  1. The claim is made in good faith;
  2. Supporting data are accurate and complete to the best of the contractor's knowledge;
  3. The amount requested accurately reflects the contract adjustment for which the contractor believes the Government is liable;
  4. The certifier is duly authorized to bind the contractor.

| 1. Accrual of Claim ==> Must file Claim within 6 YEARS (Statute of Limitations)   |

|    - Option B: File lawsuit at COFC within 1 YEAR (12 MONTHS)                     |
+-----------------------------------------------------------------------------------+

3. Contracting Officer Final Decision (COFD) & Appeals

COFD Timelines (FAR 33.211)

  • Claims <= $100,000: The CO must issue a written Contracting Officer Final Decision (COFD) within 60 calendar days of receipt.
  • Claims > $100,000: Within 60 calendar days, the CO must either issue a COFD or notify the contractor of the firm date when a decision will be rendered.
  • Deemed Denial: Failure by the CO to issue a decision within 60 days constitutes a deemed denial, authorizing the contractor to file an immediate appeal.

Appellate Forum Selection & Strict Timelines

If dissatisfied with a COFD, the contractor has two mutually exclusive appellate choices:

  1. Board of Contract Appeals (ASBCA or CBCA): Must file appeal within 90 calendar days from receipt of the COFD (41 U.S.C. 7104(a)).
  2. U.S. Court of Federal Claims (COFC): Must file suit within 1 year (12 months) from receipt of the COFD (41 U.S.C. 7104(b)).

CDA Interest Accrual

Under FAR 33.208, interest on approved contractor claims accrues from the date the CO receives the claim (or certified claim for amounts >$100K) until payment, at rates established by the Secretary of the Treasury.


4. Contract Closeout Timelines & Procedures (FAR Subpart 4.8)

Contract closeout ensures that all administrative, financial, and technical actions are complete, excess funds are de-obligated, and contract files are archived.

Physical Completion Definition (FAR 4.804-4)

A contract is physically complete when:

  1. The contractor has completed all required deliveries and the Government has inspected and accepted all supplies/services; OR
  2. All performance has expired and the Government has issued a notice of total contract termination.

Mandatory Closeout Timelines by Contract Type (FAR 4.804-1)

The Contracting Officer must execute closeout actions within rigid statutory windows following physical completion:

Contract Type / CategoryMandatory Closeout Window (FAR 4.804-1)
Simplified Acquisition Procedures (SAP)Closed immediately upon receipt of evidence of physical completion and final payment.
Firm-Fixed-Price (FFP) Contracts (Other than SAP)Closed within 6 calendar months after physical completion.
Cost-Reimbursement / Settlement of Indirect RatesClosed within 36 calendar months after physical completion (allowing rate audit).
All Other Contracts (T&M, Labor-Hour, Incentive)Closed within 20 calendar months after physical completion.

Administrative Closeout Checklist Actions

During closeout, the CO or contract administrator verifies:

  • Final invoice received and paid;
  • De-obligation of excess remaining funds via SF 30 modification;
  • Contractor release of claims executed;
  • Government property dispositioned;
  • DD Form 1597 (Contract Closeout Check-List) and DD Form 1594 (Contract Completion Statement) completed.
