Question 1: In the context of the Design-Build Institute of America (DBIA)
certification, which of the following best describes the primary role of the Design-
Build Professional (DBP) in ensuring project success?
A. To serve as a liaison between the owner and the contractor, conveying instructions
without interpretation.
B. To provide a single point of responsibility for both design and construction services
under one contract.
C. To act as a surety, guaranteeing the financial performance of the design-build entity.
D. To manage only the construction phase, while an independent architect manages the
design phase.
CORRECT ANSWER: B. To provide a single point of responsibility for both design
and construction services under one contract.
Rationale: The fundamental principle of design-build is the integration of design and
construction under a single contract, providing the owner with a single point of
responsibility. This eliminates adversarial relationships and streamlines
communication. Options A, C, and D describe roles contrary to this core tenet (clerk-of-
the-works, surety, or construction manager only).
Question 2: The DBIA defines "best value" selection as a process that evaluates:
A. Only the lowest-priced proposal that meets the minimum technical requirements.
B. Proposals based on a predetermined combination of price and technical
qualifications.
C. The qualifications of the design-builder’s key personnel without regard to cost.
D. The project schedule as the sole determining factor for award.
CORRECT ANSWER: B. Proposals based on a predetermined combination of price
and technical qualifications.
Rationale: Best value selection is a formal procurement method that weighs both price
and non-price factors (like technical approach, past performance, and key personnel) to
select the offeror that provides the greatest overall value to the owner, not necessarily
the lowest price.
Question 3: When a design-build entity is structured as a joint venture, a critical
success factor for the entity is:
,A. Separate profit centers for the design and construction arms.
B. A formal, written agreement that clearly defines roles, responsibilities, and profit-
sharing.
C. Maintaining separate liability insurance policies for each firm.
D. Allowing each partner to issue independent change orders to the owner.
CORRECT ANSWER: B. A formal, written agreement that clearly defines roles,
responsibilities, and profit-sharing.
Rationale: A joint venture (JV) requires a robust legal agreement to function effectively.
This agreement must delineate the scope of work, financial contributions, risk
allocation, and profit distribution for each JV partner. Without it, the integration central
to design-build is impossible.
Question 4: The "Gap Analysis" in the DBIA documentation process is primarily
used to:
A. Calculate the final contract price.
B. Identify and address discrepancies between the owner’s performance criteria and
the design-builder’s proposal.
C. Determine the required level of contingency for unknown site conditions.
D. Assess the environmental impact of the proposed construction.
CORRECT ANSWER: B. Identify and address discrepancies between the owner’s
performance criteria and the design-builder’s proposal.
Rationale: Gap Analysis is a quality control process used to compare the Owner's
Project Requirements (OPR) against the Design-Builder's Proposal. It ensures that all
owner criteria are addressed in the technical design and identifies any deficiencies or
"gaps" that need to be resolved before finalizing the contract.
Question 5: In the DBIA Design-Build Contract, the "Design Professional's Standard
of Care" typically requires the design professional to:
A. Guarantee that the project will be free from all defects.
B. Perform services with the skill and care used by similarly situated professionals in the
same locality.
C. Ensure the project is delivered under budget.
D. Provide a warranty for the entire project for a period of 10 years.
CORRECT ANSWER: B. Perform services with the skill and care used by similarly
situated professionals in the same locality.
Rationale: The standard of care for a design professional is generally defined as that
degree of skill, care, and diligence ordinarily possessed and exercised by members of
the same profession in the same or similar locality. It is a negligence-based standard,
not an absolute guarantee of perfection.
,Question 6: What is the primary advantage of the "Progressive Design-Build" model
compared to traditional lump-sum design-build?
A. It allows for an earlier contractor involvement in the design process.
B. It transfers all cost risk entirely to the design-builder.
C. It eliminates the need for a Request for Proposals.
D. It fixes the cost and schedule at the onset of the project.
CORRECT ANSWER: A. It allows for an earlier contractor involvement in the design
process.
Rationale: Progressive Design-Build is a two-step process where the owner selects a
design-builder based on qualifications and then "progresses" the design with the
design-builder to a specific level of detail before a price is negotiated. A key advantage
is that it allows even earlier collaboration and input from the contractor before a design
is fixed, fostering innovation.
Question 7: A central tenet of the DBIA philosophy regarding risk allocation is that
risk should be:
A. Assumed entirely by the owner.
B. Assumed entirely by the design-builder.
C. Allocated to the party best able to manage, control, or mitigate that specific risk.
D. Transferred to a third-party insurance carrier.
CORRECT ANSWER: C. Allocated to the party best able to manage, control, or
mitigate that specific risk.
Rationale: DBIA advocates for "best-value" risk allocation. This means that risks (such
as design errors, schedule delays, or site conditions) should be assigned to the party
with the most expertise and control over the outcome. This promotes efficiency and
reduces unnecessary contingencies.
Question 8: Which of the following documents is typically considered the legal
instrument that formally establishes the contract between the owner and the
design-builder?
A. The Request for Qualifications (RFQ).
B. The Basis of Design Report.
C. The Design-Build Agreement.
D. The project's Construction Documents.
CORRECT ANSWER: C. The Design-Build Agreement.
Rationale: The Design-Build Agreement is the legally binding contract executed by the
owner and the design-builder. It contains the essential terms and conditions, price,
schedule, and scope, and it incorporates other documents by reference. The RFQ, Basis
of Design, and Construction Documents are supporting documents but not the contract
itself.
, Question 9: In a design-build contract, "contract documents" typically encompass
all of the following EXCEPT:
A. The owner's project criteria.
B. The design-builder's proposal.
C. The final as-built drawings.
D. The supplemental general conditions.
CORRECT ANSWER: C. The final as-built drawings.
Rationale: The contract documents are those that define the terms and obligations of
the parties during the construction phase. As-built drawings are created during or after
construction to document what was actually built and are not part of the original
contract documents that define the work to be done.
Question 10: A "Cost Reimbursable" contract, as used in design-build, is most
appropriate when:
A. The project scope is extremely well-defined and there is low design complexity.
B. The owner requires a fully guaranteed maximum price for budget certainty.
C. The project is highly complex, and the scope is difficult to define at the outset.
D. The design-builder is willing to absorb all cost overruns.
CORRECT ANSWER: C. The project is highly complex, and the scope is difficult to
define at the outset.
Rationale: Cost Reimbursable (or Cost-Plus) contracts are used when the scope is not
well-defined or is likely to change significantly. The owner pays the actual costs incurred
plus a fee. It provides flexibility but requires significant owner oversight and trust,
making it suitable for complex or fast-tracked projects.
Question 11: The DBIA document "Design-Build for Water and Wastewater"
emphasizes that a key benefit of the delivery method is:
A. The ability to utilize low-bid procurement to minimize costs.
B. The potential to reduce project delivery time through overlapping design and
construction.
C. The mandatory separation of design and construction to ensure independent
oversight.
D. The elimination of all regulatory permitting requirements.
CORRECT ANSWER: B. The potential to reduce project delivery time through
overlapping design and construction.
Rationale: A primary benefit of design-build is the "fast-track" capability. By allowing
construction to commence on early work packages while later design elements are still
being finalized, the overall project schedule can be significantly compressed compared
to traditional design-bid-build.
