Evaluating Contractor Bids

Bid evaluation failures cost public agencies and private owners tens of millions of dollars annually through awarded contracts that later collapse into disputes, cost overruns, or contractor default. The process of evaluating contractor bids is not a formality — it is a structured risk-assessment exercise that determines whether a project gets built on time, on budget, and to specification. On Guam, where construction activity spans military base infrastructure, civilian commercial work, and public agency projects subject to federal procurement rules, understanding bid evaluation methodology is a baseline professional requirement.

The Two Core Evaluation Frameworks

Federal procurement operates under two distinct paths, each with separate evaluation logic.

Sealed Bidding under FAR Part 14 awards to the lowest responsive, responsible bidder. There is no scoring of qualitative factors — price governs, provided the bidder meets responsiveness and responsibility thresholds. A bid is responsive if it conforms to all material terms of the solicitation. A bid is responsible if the bidder has the financial capacity, technical ability, equipment, and integrity to perform.

Competitive Negotiation under FAR Part 15 introduces best-value determinations. Here, technical merit, past performance, and management approach are scored against price. A higher-priced bid can win if the technical evaluation panel determines the premium is justified by demonstrably superior performance factors.

Construction contracts on federal projects — including the significant volume of U.S. military work on Guam — fall under FAR Part 36, which adds construction-specific requirements including the examination of unbalanced bids, the review of subcontractor listings, and scrutiny of bid bonds and performance and payment bond capacity.

Reviewing Bid Components

Every responsive construction bid contains discrete components that must be evaluated individually before comparing total prices.

Base Bid vs. Alternates: Separate base bid from additive or deductive alternates. Compare alternates consistently — two bids priced the same on base scope may diverge sharply when alternates are included in the award.

Unit Prices: When a solicitation includes unit price schedules, check for unbalanced loading. FAR Part 14 specifically addresses materially unbalanced bids — where a bidder inflates unit prices for early-schedule line items and deflates later ones to front-load cash flow. This is a valid ground for rejection.

Bid Bond: Federal construction solicitations require a bid bond equal to 20 percent of the bid amount (according to FAR 28.101-2). Verify the surety is listed on the U.S. Treasury Department's Circular 570 list of acceptable sureties.

Subcontractor Listings: Some jurisdictions and federal solicitations require prime contractors to list subcontractors for designated trades at the time of bid. Verify the listed subs are licensed and qualified for the work scope assigned.

Responsibility Determination

Price alone does not make a contractor qualified. Under 10 CFR § 436.32 and 10 CFR § 436.33, qualified contractor list procedures require affirmative findings on financial capacity, technical capacity, and performance history before a contractor can be considered for award.

For construction-specific responsibility, evaluators examine:

Labor Rate and Wage Compliance

For federally funded construction in Guam, Davis-Bacon Act prevailing wage requirements apply. A bid that appears low because it prices labor below the applicable wage determination is not a savings — it is a compliance failure waiting to happen. Verify that labor rates in submitted schedules of values align with the current Department of Labor wage determination for the applicable trade classifications.

The Bureau of Labor Statistics reports that construction managers' median annual wages nationally are a useful benchmark for assessing whether general conditions costs embedded in bids reflect realistic staffing.

Small Business and Size Standard Considerations

On set-aside contracts, contractor eligibility depends on meeting SBA size standards for construction. For general building construction, the SBA size standard is typically $45 million in average annual receipts, though this varies by NAICS code. A bid submitted by a firm that does not qualify under the applicable size standard is non-responsive and must be rejected without further evaluation.

Bid Protest Risk

A poorly documented or inconsistently applied evaluation creates protest exposure. The GAO Bid Protest Regulations at 4 CFR Part 21 govern federal protest procedures. GAO resolves approximately 2,500 protests per year (according to GAO Annual Report data). The most common sustained protest grounds are: failure to follow stated evaluation criteria, unequal treatment of offerors, and inadequate documentation of the source selection decision.

Evaluation panels must apply criteria exactly as stated in the solicitation. If price-to-technical tradeoff is described, document the tradeoff analysis. If responsibility determinations are made, record them. An award that cannot be defended with a paper trail is an award that will not survive challenge.
