Scenario-Based Practice Questions with
Answers & Rationales
Section 1: Guiding Principles & Foundations
of Design-Build Done Right (Questions 1–16)
Q1. A public owner is evaluating project delivery methods for a new wastewater treatment
facility. The owner's primary concern is minimizing total project duration and reducing the
risk of change orders during construction. Which procurement approach BEST aligns with
these objectives?
A. Design-Build, because the design-builder can overlap design and construction activities
and assumes the risk of design errors and omissions, reducing the likelihood of change
orders.
B. Design-Bid-Build, because the owner retains full control over the design and can approve
every detail before construction begins, thus avoiding changes.
C. Design-Build, because the owner can select the lowest-price bidder for construction,
ensuring the lowest initial cost and no changes.
D. Design-Bid-Build, because the design is fully developed before pricing, eliminating any
potential for change orders during construction.
Answer: A
Rationale: Design-build allows the design-builder to overlap design and construction
activities (fast-tracking) and assume single-point responsibility for design errors and
omissions, which significantly reduces the likelihood of change orders. Design-bid-build
(Option B) separates design and construction, creating finger-pointing and change-order risk.
Options C and D mischaracterize design-build procurement (lowest-price selection is
discouraged) and DBB's ability to eliminate change orders.
Why the wrong options are wrong:
• B: DBB does not "avoid changes"; it often increases them because the owner retains
coordination risk between separate designer and contractor.
• C: Design-build best practice favors best-value selection, not lowest-price bidding,
and no delivery method guarantees "no changes."
, • D: Fully developed design before pricing does not eliminate changes; it often reveals
unforeseen conditions after construction begins.
Q2. In a design-build project, what is the single point of responsibility principle?
A. Only the architect is responsible for all project outcomes
B. One entity is responsible for both design and construction, creating accountability for the
entire project
C. The owner holds all responsibility regardless of contract terms
D. Responsibility is equally divided among all subcontractors
Answer: B
Rationale: The single point of responsibility means one entity (the design-builder) holds a
single contract with the owner for both design and construction, creating primary
accountability for the entire project. This contrasts with traditional delivery where
responsibility is fragmented between architect and contractor.
Why the wrong options are wrong:
• A: In design-build, the design-builder—not the architect alone—holds consolidated
responsibility.
• C: The owner transfers design and construction risk to the design-builder through
contract terms.
• D: Subcontractors have their own scopes, but the design-builder is the single point of
accountability to the owner.
Q3. Which of the following is NOT typically an advantage of design-build delivery?
A. Accelerated project schedule through overlapping phases
B. Single point of responsibility and reduced disputes
C. Guaranteed final price established before any design work begins
D. Enhanced collaboration between design and construction teams
Answer: C
Rationale: While design-build offers cost certainty, it is typically achieved through a
Guaranteed Maximum Price (GMP) developed after preliminary design work, not before any
design begins. Establishing a guaranteed price before design would eliminate the
constructability benefits that design-build provides.
Why the wrong options are wrong:
• A: Schedule acceleration through fast-tracking is a genuine design-build advantage.
• B: Single-point responsibility genuinely reduces disputes.
, • D: Enhanced collaboration is a core design-build benefit.
Q4. According to DBIA, what is the core of every certification course?
A. Design-Build Done Right
B. Lowest-Cost Delivery
C. Traditional Project Management
D. Construction-First Methodology
Answer: A
Rationale: "Design-Build Done Right" is the core philosophy of every DBIA certification
course. It emphasizes the collaborative, integrated team approach that applies to projects of
all sizes and types.
Q5. How many Best Practices does DBIA define, and how are they organized?
A. 5 Best Practices organized into Planning, Design, Construction
B. 10 Best Practices organized into Procurement, Contracting, and Execution
C. 15 Best Practices organized into Pre-Award, Award, Post-Award
D. 8 Best Practices organized into People, Process, Technology
Answer: B
Rationale: DBIA defines 10 Best Practices organized into three categories: Procurement,
Contracting, and Execution. These are implemented through 59 discrete Implementing
Techniques.
Q6. What is an Implementing Technique in the context of DBIA Best Practices?
A. A legally binding contract clause
B. A discrete way to implement a Best Practice
C. A type of project delivery method
D. A certification exam question format
Answer: B
Rationale: Implementing Techniques are essentially "mini" best practices—discrete,
actionable ways to implement the high-level Best Practices. There are 59 of them,
categorized under Procurement, Contracting, and Execution.
Q7. In which year was the Design-Build Institute of America established?
A. 1993
B. 1995
C. 1998
D. 2001
Answer: A
