SECTION ONE: QUESTIONS 1-50
1. Which of the following best defines the core principle of design-build project delivery?
A. The owner contracts separately with a designer and a constructor who are required to work together.
B. A single entity holds a single contract with the owner for both the design and construction of a project.
C. The designer is hired by the construction manager to produce the construction documents.
D. The owner manages separate contracts for design and construction with a guaranteed maximum price.
Correct Answer: B. A single entity holds a single contract with the owner for both the design and
construction of a project.
Rationale: The fundamental principle of design-build is the integration of design and construction services
under a single contract with the owner. This creates a single point of responsibility, which is the hallmark of the
delivery method. Option A describes a traditional design-bid-build or a multi-prime approach. Option C
describes a construction management at-risk scenario. Option D describes a construction management multi-
prime approach. Understanding this core definition is essential for all exam preparation and forms the basis for
the DBIA certification.
,2. In a design-build project, what is the primary role of the owner during the proposal phase?
A. To provide a complete set of construction documents for pricing.
B. To manage the subcontractor bidding process.
C. To develop the Request for Proposals (RFP) and clearly define the project scope and performance criteria.
D. To assume all liability for design errors discovered after construction begins.
Correct Answer: C. To develop the Request for Proposals (RFP) and clearly define the project scope and
performance criteria.
Rationale: The owner's primary role is to articulate their needs through a well-crafted RFP, which includes
performance criteria and scope requirements. This allows the design-build team to propose the best solution.
Option A is incorrect because in design-build, the design team is part of the contractor's team, so the owner
does not provide the construction documents for pricing. Option B is the contractor's responsibility. Option D is
a risk the owner tries to mitigate through the contract, not a primary role.
3. Which of the following is considered a critical factor in achieving successful design-build project
outcomes?
A. Minimal interaction between the design and construction teams during the design phase.
B. A highly prescriptive and detailed set of owner requirements.
C. A culture of collaboration and open communication among all project stakeholders.
D. The use of the lowest-cost selection criteria as the sole determinant for award.
,Correct Answer: C. A culture of collaboration and open communication among all project stakeholders.
Rationale: Design-build thrives on the integration of the design and construction teams, which necessitates a
strong collaborative culture. This leads to innovation, efficiency, and reduced conflict. Option A is contrary to
the core principle of integration. Option B can stifle innovation, as the designer-builder's expertise is best used
to meet performance criteria. Option D is discouraged; the best-value selection process is a hallmark of quality
design-build.
4. The DBIA's "Design-Build Done Right" philosophy is based on which fundamental principle?
A. The owner must retain a separate engineer to oversee the design-builder.
B. The design-builder is solely responsible for all project risk without exception.
C. The owner, design-builder, and other stakeholders work together in an integrated, collaborative process.
D. Design-build is only suitable for large, complex public works projects.
Correct Answer: C. The owner, design-builder, and other stakeholders work together in an integrated,
collaborative process.
Rationale: "Design-Build Done Right" emphasizes the collaborative, integrated team approach. It is a
philosophy that applies to projects of all sizes and types. Option A is incorrect; this creates an adversarial
relationship. Option B is incorrect because risk is shared and managed contractually. Option D is a common
misconception, as design-build is used across many sectors.
, 5. Which of the following project delivery methods creates the greatest potential for cost savings through
value engineering during the design phase?
A. Design-Bid-Build
B. Design-Build
C. Construction Manager at Risk (CMAR)
D. Multi-Prime
Correct Answer: B. Design-Build
Rationale: In design-build, the design and construction teams are integrated from the start, allowing for real-
time feedback on constructability and cost. This integration facilitates value engineering during the design
development phase, rather than after the design is complete. In Options A and D, the design is largely complete
before a contractor is involved. In CMAR, while the CM is involved early, the designer is often still a separate
entity, making the collaboration less seamless.
6. A design-build proposal is best evaluated using:
A. Only the lowest construction cost.
B. The qualifications of the design-builder alone.
C. A best-value selection process that weighs both qualifications and price.
D. A random lottery among pre-qualified firms.
