6.3 Consultant Selection, Qualifications-Based Selection & Scope Boundaries
Key Takeaways
- Qualifications-Based Selection, established federally by the Brooks Act, requires selecting design professionals on competence and past performance before any fee is negotiated.
- An RFQ solicits qualifications for ranking, while an RFP solicits an approach and often a fee — the sequence matters under QBS.
- Consultant scope boundaries must be written explicitly, especially for delegated design, plenum coordination, and where civil drawings meet the architectural site plan.
- Consultants engaged by the architect are subconsultants the architect coordinates and is responsible for to the owner.
- Moving a consultant to the owner’s agreement lowers the architect’s fee and exposure but removes the architect’s contractual leverage over that consultant’s schedule.
Consultant Selection & Qualifications-Based Selection (QBS)
Architects rarely deliver buildings in isolation; contemporary facilities require an array of licensed engineering and specialty consulting professionals.
Primary Engineering & Specialty Disciplines
- Structural Engineers: Design foundations, structural framing (steel, concrete, mass timber, masonry), and lateral-force-resisting systems (wind, seismic).
- MEP/FP Engineers: Design mechanical HVAC systems, electrical power distribution, emergency lighting, plumbing fixtures and piping, and fire suppression systems.
- Civil Engineers: Design site grading, surface stormwater management, retention basins, vehicular access, and utility connections.
- Geotechnical Engineers: Perform subsurface soil borings and laboratory testing to evaluate bearing capacity, water tables, and seismic soil site class. Note: Under AIA Document B101 Section 5.5, the geotechnical engineer is customarily contracted and paid directly by the Owner, though coordinated by the Architect.
- Specialty Consultants: Building envelope/waterproofing consultants, acoustic engineers, lighting designers, landscape architects, sustainability/LEED consultants, and hardware specifiers.
Qualifications-Based Selection (QBS)
The procurement of architectural and engineering services should never be driven by low-bid pricing. Design fees represent a tiny fraction (typically 5%–10%) of initial construction cost and less than 1% of a facility's life-cycle cost, yet design quality dictates construction accuracy, operational energy efficiency, and long-term maintenance expenses.
Qualifications-Based Selection (QBS) is an objective procurement process wherein professional design firms are evaluated and selected strictly on the basis of competence, qualifications, past performance, and specialized expertise, rather than fee bidding:
- The Brooks Act (Public Law 92-582, 40 U.S.C. 1101 et seq.): Enacted by the U.S. Congress in 1972, the Brooks Act mandates that the federal government use QBS to procure architectural and engineering services. Most state and municipal jurisdictions have enacted corresponding "Mini-Brooks Acts" for public projects.
- The QBS Process Flow:
- Issuance of RFQ: The client issues a Request for Qualifications (RFQ) outlining project scope, schedule, and required competencies.
- Evaluation & Shortlisting: The client evaluates submitted qualification statements (resumes, project portfolios, references) and shortlists the top 3 to 5 firms.
- Interviews & Final Ranking: Shortlisted firms present their project approach and team capabilities. The selection committee ranks the firms in order of qualification (1st, 2nd, 3rd).
- Fee Negotiation with #1 Ranked Firm: The client enters fee negotiations solely with the highest-ranked firm to establish fair and reasonable compensation for the detailed scope.
- Resolution or Termination: If mutual agreement on fee cannot be reached, negotiations with the top firm are formally terminated in writing. The client then opens negotiations with the second-ranked firm. The client cannot reopen negotiations with the first firm once terminated.
RFQ vs. RFP
- Request for Qualifications (RFQ): Focuses exclusively on credentials, experience, firm capacity, and staff resumes. No fee proposals are submitted.
- Request for Proposals (RFP): Solicits a detailed project execution plan, methodology, schedule, and—where permitted by law in private sectors—a formal fee proposal.
Matching Consultant Scope to Project Need
Selecting the discipline is only half the decision; the other half is defining the scope boundary so that nothing falls between the architect and the consultant.
| Discipline | Typically engaged when | Common scope gap to close |
|---|---|---|
| Structural | Every project with a structural frame | Who sizes delegated-design elements such as joists, trusses, and curtain wall anchors |
| Mechanical / Electrical / Plumbing | Every conditioned building | Who locates equipment in the ceiling plenum and who resolves clashes |
| Civil | Any project with site work | Where the civil drawing stops and the architectural site plan begins, usually 5 feet from the building |
| Geotechnical | Any project with a foundation | Whether the report covers the final building footprint after the design shifted |
| Landscape | Sites with planting, hardscape, irrigation | Irrigation controls and their power and water connections |
| Acoustical | Assembly, education, healthcare, residential | Whether the consultant specifies assemblies or only sets performance targets |
| Code / life-safety | Complex or alternative-means projects | Who signs and submits the code analysis narrative to the AHJ |
| Cost estimating | CM at Risk, public work, tight budgets | Which phase estimates are contractually required |
Retained by the Architect or by the Owner?
Consultants engaged by the architect are subconsultants: the architect coordinates them, is responsible to the owner for their work, and pays them. Consultants engaged directly by the owner are the owner's consultants: the architect coordinates with them but does not warrant their work, and the owner's agreement must obligate them to deliver information in time to support the design schedule.
That distinction drives both fee and risk. Moving a consultant from the architect's agreement to the owner's agreement reduces the architect's fee and the architect's exposure, but it also removes the architect's contractual leverage over the consultant's schedule.
A public school district issues a Request for Qualifications (RFQ) for the design of a new comprehensive high school. Under Qualifications-Based Selection (QBS) guidelines (rooted in the federal Brooks Act), how must the architect selection and fee negotiation process be conducted?
