Protest Rights and Price Reasonableness in Government Contracting

Two Contracting Concepts That Most Candidates Get Wrong: Protests and Price Reasonableness

Bid protests and price reasonableness determinations are both areas where federal contracting officers make avoidable mistakes — and where DAU's FAC-C curriculum expects genuine understanding, not surface familiarity. These topics appear repeatedly across all three FAC-C levels, and the exam scenarios around them are deliberately ambiguous. Here's what you need to understand about both to get them right.

What Is a Bid Protest?

A bid protest is a formal challenge by an interested party — typically a vendor — to a contracting officer's procurement decision. Protests can challenge solicitation terms (pre-award protests) or the selection of a competitor for award (post-award protests). The three primary forums for bid protests in federal procurement are:

• Agency-level protests: Filed directly with the contracting activity. The agency's own protest reviewing official evaluates the protest. Fastest to resolve (typically within 35 days), but the least independent review.
• GAO protests: Filed with the Government Accountability Office under the Competition in Contracting Act. GAO has 100 days to issue a decision (65 days for expedited or "express" procedures). GAO sustains roughly 12–15% of protests decided on the merits each year, though many are dismissed or withdrawn before decision.
• Court of Federal Claims (COFC): Federal court with jurisdiction over bid protests. Used for complex cases or when GAO has already denied a protest and the protester seeks de novo review. COFC proceedings are more expensive and slower but provide full judicial review.

FAC-C candidates need to understand the timeliness rules for protests — a critical area where small timing errors can result in protest dismissal. For GAO protests, a pre-award protest must be filed before the proposal due date if based on a solicitation deficiency that was apparent before that date. A post-award protest must be filed within 10 days of contract award or within 10 days of when the basis for protest is known or should have been known.

Automatic Stay: When a Protest Stops Performance

One of the most operationally significant protest consequences: when a post-award protest is filed at GAO within 10 days of contract award (or 5 days of a debriefing), an automatic stay of contract performance is triggered. The contractor cannot begin performing until GAO resolves the protest (or the agency issues an override).

The agency head can override the automatic stay if urgent and compelling circumstances require performance to proceed. This override authority is exercised sparingly and must be documented. For FAC-C candidates, understanding when an automatic stay applies and when an override is justified is a scenario that appears regularly in coursework and assessments.

Common Protest Grounds That Contracting Officers Control

Most successful bid protests at GAO are sustained on grounds that a careful contracting officer could have prevented. The most common sustained protest grounds include:

• Unequal treatment of offerors: Applying different evaluation standards to different proposals, or holding discussions with one offeror about a deficiency without giving other offerors the same opportunity.
• Failure to evaluate in accordance with stated criteria: Evaluating proposals against factors not stated in the solicitation, or ignoring stated factors in the evaluation.
• Misleading discussions: During negotiations, telling an offeror their proposal is acceptable in an area where it actually has a deficiency, then using that deficiency against them in selection.
• Improper sole-source award: Awarding without competition when the statutory exceptions don't apply or when a proper J&A wasn't obtained.
• Inadequate documentation of the source selection decision: Unable to reconstruct the evaluation from the documentation — a pervasive problem in complex acquisitions.

The recurring theme: documentation. Most sustained protests involve situations where the agency made the right decision but couldn't prove it because the record was incomplete.

Price Reasonableness: What the Standard Actually Requires

FAR 15.402 requires that contracting officers purchase supplies and services at fair and reasonable prices. This is a legal requirement — not a preference — and the contracting officer, not the contractor, bears the burden of making and documenting the price reasonableness determination.

The standard is not "lowest available price." A fair and reasonable price is one that a prudent person would pay for the required supply or service in the context of the marketplace. The determination requires analysis, not just assertion.

Methods for Determining Price Reasonableness

FAR 15.404-1 identifies the techniques contracting officers can use to assess price reasonableness. They're listed in order of preference:

1. Adequate price competition: If two or more responsible offerors submit priced offers and the award is made at the lowest evaluated price, price is presumed reasonable. This is the strongest basis — competition itself creates the market test.
2. Comparison to prior prices: Compare the proposed price to prices paid for the same or similar items in prior government contracts. Must account for any differences in quantity, terms, or market conditions.
3. Comparison to commercial prices: Use catalog prices, market surveys, or published commercial price lists to establish what commercial buyers pay for comparable items.
4. Parametric estimates or should-cost analysis: Build an independent cost estimate based on engineering data, historical experience, or cost modeling. Used when competition is unavailable and prior pricing data is limited.
5. Cost analysis: Evaluate the specific elements of the proposed price (direct labor, materials, overhead, profit) to assess whether each element is reasonable. Required when cost or pricing data is required (typically for non-commercial sole-source contracts above $2 million).

Certified Cost or Pricing Data: When Is It Required?

The Truth in Negotiations Act (TINA), codified in 10 U.S.C. 2306a and 41 U.S.C. 3502, requires contractors to submit certified cost or pricing data for prime contracts and modifications above the TINA threshold (currently $2 million). Certified data means the contractor attests that the data is accurate, complete, and current as of the date of agreement.

Exceptions exist: commercial items are exempt, acquisitions at established catalog prices with adequate competition are exempt, and the contracting officer can waive the requirement when cost or pricing data would not provide meaningful additional information. FAC-C candidates at all levels must know both the requirement and the exceptions — the exam frequently presents scenarios where the question is whether TINA applies.

How Price Reasonableness and Protests Intersect

Many bid protests specifically challenge the agency's price reasonableness determination — arguing that the contracting officer accepted an unreasonably high price from the selected contractor, or that the contracting officer's evaluation of price was inconsistent with the stated evaluation criteria. When price reasonableness documentation is thin, protests in this area are more likely to succeed. The same documentation discipline that prevents procurement errors also defeats protests.

Apply These Concepts to Real Scenarios

SimpuTech's GSA Contracting AI tutor walks you through protest scenario questions (when to stay, when to override, what protest grounds GAO sustains) and price reasonableness determination scenarios (which method applies, when TINA is triggered, what documentation is required). Both topics appear at every FAC-C level. Start practicing free at SimpuTech →
