Basis of Award (BA)
Basis of Award (BA) is the documented evaluation methodology a federal agency uses to determine which offeror receives a contract award, defined in Section M and the Source Selection Decision Document.
What Is Basis of Award?
The Basis of Award is the agency's decision rule for selecting among competing offerors. Section M identifies the evaluation factors, the relative importance of each, and the methodology for combining factor ratings into an overall best-value or LPTA decision.
Common BAs include: Lowest Price Technically Acceptable (LPTA), where the lowest-priced proposal that meets all technical requirements wins; Best Value Tradeoff, where the agency selects the proposal offering the best combination of factors even if it is not the lowest price; and Cost-Technical Tradeoff, where price and technical merit are weighed against each other. Each BA structure produces a different competitive dynamic.
LPTA favors price-aggressive offerors; Best Value Tradeoff favors offerors with strong technical, management, and past performance differentiators. The contractor's capture team studies the BA carefully to design a proposal that aligns with the agency's decision rule.
Key Characteristics
Basis of Award structures have several defining attributes. They are documented in Section M of the solicitation, with specific evaluation factors and their relative importance.
They define the relationship between price and non-price factors (e.g., "technical is more important than price" or "all factors are approximately equal"). They establish the rating scales used to evaluate each factor (e.g., color ratings, adjectival ratings, or numeric scores).
They specify whether the contracting officer will award based on lowest price among technically acceptable proposals or through a tradeoff analysis. They form the basis of the Source Selection Decision Document.
Each characteristic shapes how the offeror prioritizes proposal investment across technical depth, management approach, and pricing strategy.
How It Works in Government Contracting
Basis of Award operates at three points in the federal procurement cycle. First, during solicitation preparation, the contracting officer and source selection team define the BA in the Source Selection Plan and codify it in Section M. The BA reflects the agency's risk tolerance and what it values most in the procurement.
Second, during proposal preparation, offerors study Section M and structure their proposals to maximize their score under the BA. An LPTA-driven proposal emphasizes meeting requirements at low price; a Best Value Tradeoff proposal emphasizes technical depth, management strength, and past performance differentiation.
Third, during source selection, the evaluation team applies the BA to evaluate each proposal against the factors in Section M and produces a Source Selection Decision Document explaining why the selected offeror best meets the BA. The contracting officer reviews and approves the SSDD, then issues the Notice of Award.
Real-World Example
A federal agency releases an RFP for a $25 million cybersecurity services contract. Section M establishes the Basis of Award as best value tradeoff with the following factors: Technical Approach (most important), Management Approach (slightly less important than Technical), Past Performance (less important than Management), and Price (less important than Past Performance but a substantial consideration).
Four offerors submit proposals. The lowest-priced offeror submits at $19 million with a Satisfactory technical rating.
A higher-priced offeror submits at $23 million with an Outstanding technical rating, Exceptional management, and Substantial Confidence in past performance. The source selection team evaluates the four proposals and documents the tradeoff analysis in the Source Selection Decision Document, selecting the $23 million offeror.
The SSDD concludes that the $4 million premium is justified by significantly stronger technical and management capability and a track record of similar successful contracts.
Regulatory Framework
Basis of Award is governed by FAR Part 15 (Contracting by Negotiation), particularly FAR 15.101 (Best Value Continuum), FAR 15.101-1 (Tradeoff Process), FAR 15.101-2 (Lowest Price Technically Acceptable Source Selection Process), and FAR 15.304 (Evaluation Factors and Significant Subfactors). FAR 15.305 governs the proposal evaluation process; FAR 15.306 governs discussions; FAR 15.308 requires a Source Selection Decision Document.
Procurement integrity is governed by FAR Subpart 3.1 and the Procurement Integrity Act. Source selection decisions can be challenged through bid protests.
GAO sustains protests when the source selection decision does not align with the documented Basis of Award, when the evaluation is unreasonable, or when the SSDD fails to explain the rationale for the award.
Why It Matters for Contractors
The Basis of Award shapes the entire competitive landscape of a procurement. An LPTA procurement rewards offerors that can deliver compliant technical solutions at low price; a Best Value Tradeoff procurement rewards offerors with strong technical, management, and past performance differentiators.
Misreading the BA leads to wasted proposal investment: heavy technical depth in an LPTA procurement adds cost without adding score, and aggressive pricing in a Best Value Tradeoff procurement sacrifices margin without winning the contract. The BA interacts with the compliance matrix (which tracks Section L and Section M requirements), with Section L (proposal instructions), with the source selection rating scales, and with the debriefing (where unsuccessful offerors learn how the BA was applied).
Capture teams that read the BA carefully and structure proposals accordingly win at materially higher rates than teams that treat every procurement the same way.
Common Misconceptions
LPTA always means the lowest price wins.
No. LPTA means the lowest-priced proposal that meets all technical requirements wins. An offeror that submits a low price but fails any technical requirement is eliminated. The lowest price among technically acceptable proposals wins, not the lowest price overall.
Best Value Tradeoff means price doesn't matter.
No. Price is always evaluated. In a Best Value Tradeoff, the agency may select a higher-priced proposal if the technical and management premium justifies the cost. The SSDD must document that the premium is worth the cost.
The Basis of Award is the same for every procurement.
No. Each procurement establishes its own BA in Section M. The same agency can use LPTA for one procurement and Best Value Tradeoff for another based on what it values most for each acquisition.
Frequently Asked Questions
Where is the Basis of Award documented?
Section M (Evaluation Factors for Award) of the solicitation, supplemented by the Source Selection Plan (an internal agency document) and the Source Selection Decision Document (the final award documentation).
What is the difference between LPTA and Best Value Tradeoff?
LPTA selects the lowest-priced proposal that meets all technical requirements (pass/fail technical evaluation). Best Value Tradeoff allows the agency to weigh technical, management, past performance, and price together, sometimes selecting a higher-priced proposal if the technical premium is justified.
Can the agency change the Basis of Award after release?
Yes, through a formal solicitation amendment. The amendment provides offerors notice of the change and an opportunity to revise their proposals. Changes to the BA after award are difficult and usually require re-competition.
What if the SSDD doesn't clearly explain the award decision?
This is a frequent basis for sustained bid protests. The SSDD must document the tradeoff analysis (for Best Value Tradeoff) or the technical acceptability determination (for LPTA), and explain why the selected offeror best meets the BA. Vague or conclusory SSDDs are vulnerable to challenge.
