7.3 QBS, Subcontractors and Construction Compliance

Qualifications-Based Selection (QBS) & The Brooks Act

While standard public construction contracts are awarded to the lowest responsive and responsible bidder, the procurement of professional Architectural, Engineering (A&E), Land Surveying, and Landscape Architecture services is governed by an entirely different statutory principle: Qualifications-Based Selection (QBS).

The Brooks Act (40 U.S.C. 1101 et seq.)

Enacted by Congress in 1972, the federal Brooks Act mandates that the selection of architectural and engineering services must be based on demonstrated competence and professional qualifications, rather than competitive fee bidding. State “Mini-Brooks” laws may impose similar selection procedures; covered services, thresholds, and local applicability differ.

The Strict QBS Procedural Protocol

Public buyers procuring A&E services under QBS must adhere to a strict sequential protocol. Evaluating or ranking design firms on the basis of cost or hourly rates during the initial selection phase is a statutory violation.

Strict QBS Sequential Process:
Step 1: Request for Qualifications (RFQ) Public Notice
         │
Step 2: Technical Evaluation & Ranking (Qualifications, Past Performance, Personnel)
         │  (Strict prohibition against requesting or evaluating price)
         ▼
Step 3: Establish Ranked Shortlist (Rank #1, Rank #2, Rank #3)
         │
Step 4: Negotiate Scope & Fee ONLY with Firm #1
         │
         ├── [ Agreement Reached on Fair & Reasonable Fee ] ──> Award Contract
         │
         └── [ Impasse Reached ] ──> Formally Terminate Negotiations in Writing with Firm #1
                                      │
                                      ▼
                                     Step 5: Initiate Negotiations with Firm #2
                                     (Negotiations with Firm #1 CANNOT be reopened)

1. Request for Qualifications (RFQ): The agency publishes an RFQ inviting statements of qualifications. Evaluation factors focus exclusively on demonstrated professional competence, relevant project experience, qualifications of assigned key personnel, firm capacity, and past performance.
2. Evaluation and Ranking: An independent evaluation committee evaluates submissions and interviews shortlisted firms. The committee produces a final ordinal technical ranking (e.g., Firm 1, Firm 2, Firm 3).
3. Sequential Price Negotiation: The public agency requests a detailed cost and fee proposal only from the top-ranked firm (Firm 1). The agency enters into scope and price negotiations to establish a compensation amount determined to be fair and reasonable to the public agency.
4. Handling an Impasse: If the agency and Firm 1 cannot reach agreement on project scope, staffing, or fair compensation, the agency must formally terminate negotiations in writing with Firm 1. Only after formal written termination may the agency open negotiations with the second-ranked firm (Firm 2). The agency cannot reopen negotiations with Firm 1 or conduct simultaneous negotiations to create price leverage.

Subcontractor Listing Laws and Anti-Bid Shopping Protections

In public works sealed bidding, general contractors rely heavily on specialty trade subcontractors (e.g., electrical, mechanical, plumbing, structural steel). To protect the public bidding process from predatory contracting behaviors, many jurisdictions enforce subcontractor listing laws.

Predatory Trade Practices

• Bid Shopping: After winning a public contract as the low bidder, the general contractor approaches competing trade subcontractors and uses the lowest received subcontractor quote to pressure other firms into undercutting that price, pocketing the resulting cost difference as additional contractor profit without reducing the cost to the public owner.
• Bid Peddling: An unethical subcontractor approaches the winning general contractor after bid opening and offers to undercut the subcontractor price used in the winning general bid, attempting to displace the original firm.

The Subcontractor Listing Remedy

Subcontractor listing statutes require general contractors to list their key specialty trade subcontractors and corresponding bid values on their bid submission forms at the time of formal bid opening. Once the prime contract is awarded:

• The general contractor is legally obligated to execute subcontracts with the listed trade firms.
• The general contractor cannot substitute a listed subcontractor without obtaining prior written approval from the public procurement officer, granted only for legitimate statutory grounds (e.g., subcontractor bankruptcy, refusal to execute a contract, or failure to obtain required surety bonding).

Prevailing Wages and Construction Surety Bonds

Prevailing Wage Mandates

Direct federal construction can be covered by the Davis-Bacon Act; assisted construction is covered when a Related Act applies. State prevailing-wage requirements apply where enacted and applicable. Verify coverage rather than assuming every public project has the same wage mandate. These statutes mandate that construction laborers and mechanics working on public sites receive hourly wages and fringe benefits not less than the rates and fringe benefits established by the applicable federal or state wage determination.

Public buyers must ensure that the applicable prevailing wage-determination schedule is incorporated into the solicitation. Contractors must submit weekly Certified Payroll Records (e.g., Form WH-347). Procurement administrators conduct random on-site employee interviews and audit payroll records to ensure worker classifications and wage rates comply with statutory mandates.

Construction Surety Bonds

Public property is exempt from private mechanics' liens; an unpaid subcontractor cannot foreclose on a city hall or public high school. To protect public funds and ensure trade workers and suppliers are compensated, the federal Miller Act (40 U.S.C. 3131 et seq.) and state "Little Miller Acts" establish performance and payment protection for covered construction; bid-security requirements come from the applicable procurement rules and solicitation:

1. Bid Bond (typically 5% to 10% of bid amount): Guarantees that the low bidder will execute the contract and provide required performance and payment bonds if awarded. If the bidder withdraws without legal excuse, the applicable law and bond determine recovery, which may be actual damages up to the penal sum rather than automatic full forfeiture.
2. Performance Bond (100% of contract value): Protects the public owner against contractor default, insolvency, or abandonment. If the contractor defaults, the bond governs the surety's completion, financing, tender, settlement, and defense options, subject to its conditions and penal sum.
3. Payment Bond (100% of contract value): Guarantees that the general contractor will pay all subcontractors, trade craft workers, and material suppliers. It protects trade vendors against general contractor insolvency and provides a remedy for covered claimants under the bond; it does not extinguish all third-party claims.
