5.1 Proposal Evaluation & Competitive Range Determination (FAR 15.306)

5.1 Proposal Evaluation & Competitive Range Determination (FAR 15.306)

In negotiated acquisitions conducted under FAR Part 15, proposal evaluation and exchanges with offerors represent critical, legal stages where the Government assesses offeror capabilities, determines technical acceptability, establishes competitive boundaries, and conducts discussions leading to contract award. Contracting Officers (COs) and Source Selection Evaluation Boards (SSEBs) must strictly adhere to the evaluation criteria published in Section M of the Request for Proposals (RFP) and execute exchanges in compliance with FAR 15.305 and FAR 15.306.

---

Proposal Evaluation Principles (FAR 15.305)

Proposal evaluation is an assessment of the proposal and the offeror's ability to perform the prospective contract successfully. The Government must evaluate competitive proposals solely on the factors and subfactors specified in the solicitation.

Mandatory Evaluation Factors

1. Price or Cost Evaluation (FAR 15.305(a)(1)): The Government must evaluate price or cost for every acquisition. Price reasonableness must be established for fixed-price contracts, while cost realism must be evaluated for cost-reimbursement contracts.
2. Technical Evaluation (FAR 15.305(a)(2)): Technical proposals are evaluated against solicitation requirements to assess technical capability, key personnel, management approach, and technical risk. Ratings may be adjectival (e.g., Outstanding, Good, Acceptable, Marginal, Unacceptable), color-coded, or numerical, as specified in the source selection plan.
3. Past Performance Evaluation (FAR 15.305(a)(2)): Past performance is a mandatory evaluation factor for negotiated acquisitions exceeding the Simplified Acquisition Threshold ($350,000), unless waived in writing by the CO. Evaluation considers recency, relevancy, and quality of performance. Offerors without a record of relevant past performance must receive a neutral rating (FAR 15.305(a)(2)(iv)).
4. Small Business Subcontracting Evaluation (FAR 15.305(a)(5)): For acquisitions requiring a subcontracting plan under FAR 19.702, the CO must evaluate the extent of participation of small business concerns in performance.

Exchanges with Offerors Before & After Competitive Range (FAR 15.306)

FAR 15.306 categorizes exchanges between the Government and offerors into four distinct categories based on timing, intent, and whether proposal revisions are permitted:

---

Clarifications & Award Without Discussions (FAR 15.306(a))

When the solicitation states that the Government intends to evaluate proposals and award a contract without discussions (pursuant to FAR 15.306(a)(3)), offerors are given no opportunity to revise their proposals. In this scenario, exchanges are strictly limited to clarifications.

• Definition: Clarifications are limited exchanges between the Government and offerors that occur when award without discussions is contemplated.
• Permissible Scope: Offerors may be given the opportunity to clarify certain aspects of proposals (e.g., resolving relevance of past performance, clarifying mathematical transpositions, or verifying ambiguous shipping terms).
• Prohibitions: Clarifications cannot be used to cure proposal deficiencies, material omissions, or technical unacceptable elements, nor can they allow an offeror to revise its price or technical approach.

---

Communications Before Competitive Range Establishment (FAR 15.306(b))

Communications are exchanges between the Government and offerors after receipt of proposals, leading up to the establishment of the competitive range. Communications shall not be used to permit an offeror to revise its proposal.

Mandatory & Permissible Communications

1. Adverse Past Performance: Communications must be held with offerors whose past performance information is the determining factor preventing them from being included in the competitive range, provided the offeror has not previously had an opportunity to respond to the adverse data (FAR 15.306(b)(1)(i)).
2. Ambiguities & Capability Concerns: Communications may be held with offerors whose inclusion in or exclusion from the competitive range is uncertain, to address ambiguous proposal elements or technical capability concerns (FAR 15.306(b)(1)(ii)).

---

Competitive Range Determination (FAR 15.306(c))

Following initial evaluation of all proposals against Section M criteria, the Contracting Officer establishes the competitive range. The competitive range comprises all of the most highly rated proposals, unless reduced for efficiency.

[All Initial Proposals] ➔ [Section M Evaluation] ➔ [CO Applies Competitive Range Test] ➔ [Competitive Range Established]
                                                              │
                                                              └─── Optional: Efficiency Limit (FAR 15.306(c)(2))

Establishing the Competitive Range

• Standard Rule: The CO includes all proposals that have a reasonable chance of being selected for award based on technical and price ratings.
• Efficiency Limitation: If the CO determines that the number of most highly rated proposals that would otherwise be included in the competitive range exceeds the number at which an efficient competition can be conducted, the CO may limit the competitive range to the greatest number that will permit an efficient competition among the most highly rated proposals (FAR 15.306(c)(2)). This determination must be documented in writing in the Source Selection Decision Document (SSDD).
• Debriefing & Notice: Offerors excluded from the competitive range must be promptly notified in writing (FAR 15.503(a)) and may request a pre-award debriefing under FAR 15.505.

---

Formal Discussions / Competitive Negotiations (FAR 15.306(d))

Once the competitive range is established, the CO must conduct formal discussions with every offeror included in the competitive range. Discussions are oral or written exchanges designed to allow offerors to revise their proposals to enhance award possibilities.

Mandatory Scope of Discussions (FAR 15.306(d)(3))

The Contracting Officer must tailor discussions to each offeror's proposal and must discuss:

1. Deficiencies: Any material failure of a proposal to meet a Government requirement or a combination of significant weaknesses that increases the risk of unsuccessful contract performance to an unacceptable level.
2. Significant Weaknesses: A flaw that appreciably increases the risk of unsuccessful contract performance.
3. Adverse Past Performance: Adverse past performance information to which the offeror has not yet had an opportunity to respond.
4. Other Aspects: Price, cost, or technical aspects of a proposal that could be altered or explained to enhance materially the proposal's potential for award.

Strict Prohibitions During Discussions (FAR 15.306(e))

During discussions, government personnel are strictly prohibited from engaging in conduct that favors one offeror over another. Specifically, government personnel shall NOT:

• Favor one offeror: Engage in unfair or unequal treatment.
• Reveal technical solutions: Transpose or reveal an offeror's technical solution, unique ideas, or proprietary intellectual property to another offeror (technical transposition/spoofing).
• Reveal prices: Reveal an offeror's price or fee structure to another offeror without permission (price leaks).
• Engage in auction techniques: Reveal one offeror's price to another to induce lower bids.

---

Final Proposal Revisions (FPRs) (FAR 15.307)

Upon completion of discussions, the Contracting Officer issues a written request for Final Proposal Revisions (FPRs) to all offerors remaining in the competitive range.

• Common Cut-off Date: The request for FPRs must establish a common cut-off date and time for receipt of revisions.
• Evaluation of FPRs: The SSEB evaluates the FPRs against solicitation criteria to finalize technical and cost/price ratings.
• Source Selection Decision: The Source Selection Authority (SSA) reviews final evaluation findings and executes a documented trade-off or LPTA award determination.
