Why QBS Exists: Professional Services Are Not Commodities
Qualifications-Based Selection (QBS) is the process of selecting an architect or engineer based on professional qualifications, experience, and approach - not on the basis of fee competition. The principle behind QBS is that professional design services cannot be meaningfully compared on price alone, because the quality of design has direct and lasting impact on construction cost, building performance, and safety. Selecting the cheapest architect tends to produce the most expensive building over its lifecycle.
QBS is codified at the federal level through the Brooks Act (formally the Brooks Architect-Engineers Act of 1972), which prohibits federal agencies from using price as the first criterion for selecting A/E firms. The Act requires federal agencies to rank firms by qualifications, negotiate a fair and reasonable fee with the top-ranked firm, and only move to the next firm if negotiations fail.
The Brooks Act Process
Under the Brooks Act, federal A/E selection follows a specific sequence that the ARE tests in detail:
- Public Notice: Agency publishes a notice of the project and solicits interest (Broad Agency Announcement or Commerce Business Daily notice).
- RFQ Submissions: Firms submit Standard Form 330 (SF 330) - a qualifications package including firm experience, team resumes, past project data, and approach.
- Short-List: Agency evaluates SF 330s and short-lists the most qualified firms (typically 3–6).
- Interviews (optional): Short-listed firms may present to the selection panel.
- Ranking: Selection panel ranks firms in order of qualifications.
- Fee Negotiation: Agency negotiates a fair and reasonable fee with the top-ranked firm only. Price is discussed only at this stage.
- Award or Move to Next Firm: If negotiations with the top firm succeed, the contract is awarded. If not, negotiations begin with the second-ranked firm.
RFQ vs. RFP: Understanding the Difference
The RFQ (Request for Qualifications) is the document agencies use to solicit qualifications packages. It asks firms to demonstrate their experience and competence but does NOT ask for proposed fees. The RFP (Request for Proposals) may follow the short-list and asks firms to propose a scope, schedule, and sometimes a fee range (for non-Brooks-Act projects). On the ARE, the distinction matters because Brooks Act projects use an RFQ-based process without competitive fee proposals.
State-Level QBS
Many states have enacted their own QBS laws for state and local government A/E selection. While the specific procedures vary by state, they typically mirror the federal Brooks Act approach. Some states require QBS for all public projects; others only for projects above a certain dollar threshold. The AIA and ACEC (American Council of Engineering Companies) actively advocate for QBS adoption at all levels of government.
Why This Matters Beyond Government Projects
Private owners are not bound by the Brooks Act, but the QBS process is considered best practice across the industry. AIA documents and professional guidelines consistently recommend qualifications-based selection for design services. The NCARB and AIA Code of Ethics both reflect the principle that architects should not compete on the basis of fee alone, as this undermines professional quality standards.
Key Exam Points
- Brooks Act (1972): Prohibits price as the first criterion for federal A/E selection.
- SF 330: The standard qualifications form used for federal A/E projects.
- Sequence: Qualify → Rank → Negotiate (price comes last).
- RFQ: Solicits qualifications; no fees requested.
- RFP: Solicits detailed proposals; may include fee discussion (non-QBS context).
