Bid Protest Checklist: A Practical Checklist

Document type: Checklist Practice area: Government Contracts — Bid Protests Jurisdiction: United States (federal) Last reviewed: 5 September 2026

Part 1 — Day one

Record the date of contract award: ____________
Record the date of the unsuccessful-offeror notice: ____________
Request the debriefing in writing, today, within the period the FAR allows. A late request is not a required debriefing and forfeits both the extended protest window and the automatic stay.
Retain the transmission record.
Determine whether the Department of Defense enhanced debriefing process applies (written debriefing, follow-up questions within two business days, agency response within five; the debriefing is not concluded — and the clocks do not start — until the response is delivered).
Engage counsel today, not after the debriefing.

Build the one-page calendar:

Debriefing date (or expected): ____________
STAY DEADLINE — 10 days after award, or 5 days after the required debriefing date, whichever is later: ____________
GAO MERITS DEADLINE — 10 days after the debriefing: ____________
Note the gap. A protest can be timely and still too late to stop performance under 31 U.S.C. § 3553(d).

Pull the file:

Solicitation and every amendment.
All questions and answers.
Your proposal as submitted, all volumes.
Discussions, clarifications, and final proposal revisions.
Capture team notes on the competition.

Part 2 — The debriefing

Questions drafted in advance and submitted in writing where permitted.
Ask about: significant weaknesses and deficiencies and what in the proposal produced them; evaluated price and technical rating for the awardee and for you; ranking of offerors; rationale for award and how the tradeoff was analyzed; whether a price or cost realism analysis was performed and what it assessed; which past performance was treated as relevant and why; whether discussions were held and what was raised with each offeror.
Team assembled: counsel, capture lead, proposal manager, technical lead.
One person assigned to take verbatim notes.
Do not argue. Do not defend the proposal. Do not disclose the protest theory.
Follow-up questions submitted where the process allows.
Debriefing documents retained as exhibits.

Part 3 — Screens: can we protest?

Standing — interested party under 31 U.S.C. § 3551:

Were we an actual or prospective bidder or offeror?
Is our economic interest direct — would we be in line for award if our grounds are sustained?
If offerors sit between us and the awardee, do our grounds reach them too?
Are we a subcontractor? (A subcontractor is generally not an interested party.)
At the Court of Federal Claims: can we show a substantial chance of receiving the award but for the error?

Timeliness — 4 C.F.R. § 21.2:

Is the ground a solicitation impropriety apparent on the face? If so, it had to be raised before the proposal due date — and is very likely waived. The same result follows at the court under Blue & Gold Fleet, L.P. v. United States, 492 F.3d 1308 (Fed. Cir. 2007).
All other grounds: within 10 days of when the basis was known or should have been known.
Debriefing exception applied correctly.

Grounds:

Can counsel state a specific inconsistency between what the solicitation required and what the agency did? ("We were better" is not a ground.)
Can we articulate prejudice — what a corrected evaluation would show and why it would change the award?

Part 4 — Forum

Agency-level — fast, cheap, preserves relationships; best for obvious or clerical errors, modest stakes, or to get the contracting officer's explanation on the record. Diarize the GAO deadline from the moment of filing — a subsequent GAO protest is due within 10 days of adverse agency action.
GAO — the automatic stay; a decision within 100 days under 31 U.S.C. § 3554; an agency report you will receive. The default.
Court of Federal Claims — 28 U.S.C. § 1491(b); orders rather than recommendations; injunctive relief; appealable to the Federal Circuit; no automatic stay; higher cost.
Do not file at the agency and at GAO on the same issue simultaneously without analyzing the sequencing.

Business analysis:

Contract value and remaining term.
Realistic outcome (usually a reevaluation, not an award).
Cost of the protest.
Incumbent workforce attrition if we do nothing.
Intelligence value of the agency report even in a loss.
Decision-maker identified and decision documented.

Part 5 — Drafting and filing

Required content (4 C.F.R. Part 21):

Protester's name, address, and contact information.
Solicitation or contract number.
Detailed statement of legal and factual grounds, with supporting documents.
Statement of the relief sought.
Request for a ruling.
Request for documents, identified specifically, with the reason each is needed.
Signed.

Drafting discipline:

Each ground states: what the solicitation required; what the agency did; why that was inconsistent; and, separately, why it prejudiced us.
Three well-supported grounds rather than eleven weak ones.
Grounds pleaded in the alternative where the record is unknown, without misstating what we do know.
Bad-faith allegations made only where provable — the presumption of regularity is strong.

Filing:

Filed with GAO; copy served on the contracting officer within one day.
Filed within the stay window, not merely the merits window.
GAO's notification to the agency confirmed.
Suspension of performance confirmed with the contracting officer — do not assume.
Short professional notification sent to the contracting officer.

Part 6 — The protective order

Outside counsel's application filed immediately.
Consultants' applications filed with conflict showings.
Client told, before filing, that outside counsel will see the record and the client will not.
In-house counsel performing competitive decision-making functions identified as ineligible.
Handling procedures for protected material established.

Part 7 — The agency report

Due roughly 30 days after filing.

Calendar the 10-day supplemental protest deadline on the day the report arrives — the clock runs from receipt, not from analysis.
Comments deadline calendared: 10 days.

Reading method:

Build the comparison table — one row per factor and subfactor, one column per offeror, quoting the actual evaluation language rather than the rating.
Trace every adjectival rating back to its underlying findings.
Reconcile individual evaluations against the consensus document; ask why any divergence occurred.
Read the source selection decision document last, against everything else — does it explain the tradeoff, or just announce a result?
Check the arithmetic: evaluated prices, option years, any formula.
List what is absent — a required realism analysis, a promised clarification, a received past performance questionnaire never considered. Absence beats disagreement.
Identify new grounds disclosed by the report.
Request additional documents specifically if the record is incomplete.

Part 8 — Comments and supplemental grounds

Every ground addressed. A ground not addressed is deemed abandoned.
Grounds overtaken by the record withdrawn expressly rather than by silence.
Every assertion cited to the record.
The contracting officer's statement answered where it mischaracterizes the record.
Prejudice argued separately on each ground.
Supplemental grounds filed as their own protest within 10 days of learning the basis.
Hearing requested only where a specific factual dispute exists that documents cannot resolve.
Outcome prediction ADR requested where the case is strong.

Part 9 — Corrective action

Scope assessed: is it rationally related to the identified defect, or does it fix a symptom?
If inadequate, object promptly — that challenge has its own clock.
Client told immediately what corrective action is and is not: a second evaluation, frequently reaching the same result.
Reevaluation monitored; the new award decision opens a new protest window.

If you are the awardee:

Engage agency counsel before the agency commits to corrective action.
If corrective action is taken and costs the award, evaluate a protest of the corrective action — particularly where discussions are reopened after your price was disclosed.

Part 10 — Decision and costs

Decision expected within 100 days (31 U.S.C. § 3554(a)).

If sustained:

Remedy recommended under § 3554(b): reevaluate, recompete, amend, terminate, or award consistent with law.
Costs claim filed — protest costs including attorneys' fees, and proposal preparation costs — in detail, certified, within the period GAO sets. Do not skip this.

If denied:

Court of Federal Claims considered (it reviews the procurement, not GAO's decision).
Realistic assessment: same record, deferential standard.

Either way:

Internal debrief held with capture and proposal teams on what the agency report revealed.

Part 11 — Court of Federal Claims variations

No automatic stay — TRO or preliminary injunction motion filed, addressing likelihood of success, irreparable harm, balance of harms, and public interest.
Voluntary standstill negotiated if available (a negotiation, not a right).
Complaint pleaded under 28 U.S.C. § 1491(b).
Administrative record reviewed; supplementation sought only on a showing that the record is inadequate for effective review.
Discovery sought only where bias, bad faith, or OCI is alleged.
Cross-motions for judgment on the administrative record prepared.
Standard applied: 5 U.S.C. § 706, as framed in Impresa Construzioni Geom. Domenico Garufi v. United States, 238 F.3d 1324 (Fed. Cir. 2001) — no rational basis, or a clear and prejudicial violation.
Prejudice addressed as a separate step under Bannum, Inc. v. United States, 404 F.3d 1346 (Fed. Cir. 2005).
Relief understood: declaratory and injunctive relief plus bid and proposal costs — not lost profits.
Equal Access to Justice Act fees considered.
Federal Circuit appeal deadline calendared.

Part 12 — Defending as the awardee

Intervene immediately — you are not automatically a party.
Counsel admitted under the protective order on day one.
Team briefed that they will not see the competitor's proposal or most of the record.
Filings add what the government cannot: what our proposal actually said and why the agency's reading was reasonable.
Prejudice argued hard — build the counterfactual ranking with the error corrected.
OCI defense assembled from contemporaneous documents: firewall memoranda, mitigation plans, personnel screening records.
The contracting officer's OCI analysis defended as reasonable, not just the underlying facts.
Standstill managed: subcontractor commitments, hiring offers, facilities, customer communications.
Corrective action watched and engaged before the agency commits.
Do not duplicate the government's filings — file where you add something.

Part 13 — Specialist tracks

Size and socioeconomic status — filed with the contracting officer, referred to SBA, appealable to SBA OHA. GAO will not decide size status. Window generally five business days after notice of the apparent successful offeror. Screen for this on day one.
Task and delivery orders — protestable only for increase in scope, period, or maximum value, or above the statutory threshold ($10M civilian / $25M DoD), where GAO has exclusive jurisdiction. Confirm the vehicle and order value before promising a forum.
Pre-award protests — solicitation defects, unduly restrictive specifications, improper bundling, sole-source justifications under 41 U.S.C. § 3304 against the full and open competition requirement of 41 U.S.C. § 3301. Due before the proposal deadline. Consider raising it first through written questions and answers.
Pre-award standing analyzed under Weeks Marine, Inc. v. United States, 575 F.3d 1352 (Fed. Cir. 2009), not the post-award substantial-chance test.
Stay override challenges brought at the Court of Federal Claims, immediately.
Other transaction agreements and non-FAR instruments — jurisdiction contested; see Distributed Solutions, Inc. v. United States, 539 F.3d 1340 (Fed. Cir. 2008); check current law.

Part 14 — The playbook, written before you need it

Decision-maker named, with an alternate.
Spend pre-authorized to a threshold so no budget approval is needed inside the five-day window.
Counsel pre-selected who can be admitted under a protective order and who has filed protests recently.
Standing instruction: an unsuccessful-offeror notice goes to contracts and legal the same day.
Standard debriefing request template, sent same-day by email.
Standard debriefing question set.
Solicitation review at bid/no-bid, asking whether any ground rule would be challenged — because after the closing date the answer no longer matters.
Post-protest internal debrief, every time.
OCI documentation maintained as a standing practice where the company does advisory work for offices it later competes before.
