Contracts & Project Delivery Review
• This study guide contains 200 verified practice questions covering all core
domains of the DBIA® Certified Design-Build Professional Exam 2026, designed to
simulate the real exam experience and reinforce mastery of design-build principles,
contracts, and project delivery.
• Use this material by working through each question independently before
checking the correct answer and detailed EXPERT RATIONALE below it, focusing
extra review time on any domain where you answer incorrectly.
1. What is the fundamental principle that distinguishes design-build project
delivery from design-bid-build?
A. The owner retains separate contracts with the designer and contractor
B. The contractor is responsible only for construction, not design
C. A single entity holds the contract for both design and construction
D. The designer leads the project without contractor involvement
E. The owner manages all subcontractors directly
Correct Answer: C. A single entity holds the contract for both design and
construction
EXPERT RATIONALE: Design-build is defined by a single point of responsibility
where one entity — the design-builder — is contractually responsible to the owner
for both design and construction services. This eliminates the adversarial
relationship between designer and contractor that often exists in traditional
delivery methods.
2. Which organization is the primary professional body that administers the
DBIA® certification for design-build professionals?
,A. American Institute of Architects (AIA)
B. Associated General Contractors (AGC)
C. Design-Build Institute of America (DBIA)
D. Construction Management Association of America (CMAA)
E. National Society of Professional Engineers (NSPE)
Correct Answer: C. Design-Build Institute of America (DBIA)
EXPERT RATIONALE: The DBIA is the only organization in the United States that
defines, teaches, and advocates for best practices in design-build project delivery. It
administers the DBIA® certification exam and sets the professional standards for
design-build professionals across all sectors.
3. In design-build project delivery, the term "single point of responsibility"
most accurately refers to which of the following?
A. The owner assumes all project risks
B. One entity is accountable to the owner for both design and construction
outcomes
C. The contractor manages all design decisions independently
D. The designer controls the budget without owner input
E. The surety company guarantees all project deliverables
Correct Answer: B. One entity is accountable to the owner for both design
and construction outcomes
EXPERT RATIONALE: Single point of responsibility means the design-builder cannot
shift blame between designer and contractor when problems arise, because they
are the same contracting entity. This alignment of responsibility encourages
collaboration, reduces claims, and streamlines dispute resolution for the owner.
,4. Which project delivery method typically results in the longest overall
project schedule due to sequential phases?
A. Design-build
B. Construction Manager at Risk (CMAR)
C. Design-bid-build
D. Integrated Project Delivery (IPD)
E. Public-Private Partnership (P3)
Correct Answer: C. Design-bid-build
EXPERT RATIONALE: Design-bid-build requires sequential completion of full design
before bidding can occur, and bidding must be completed before construction
begins. This linear process adds significant time compared to design-build, which
allows overlapping of design and construction phases through a process called fast-
tracking or phased construction.
5. What is "bridging" in the context of design-build project delivery?
A. A temporary construction method used during phased delivery
B. The owner's use of a design consultant to develop criteria documents before
design-builder selection
C. A financial instrument used to fund early construction activities
D. The process of transferring project risk from owner to contractor
E. A dispute resolution method used at project closeout
Correct Answer: B. The owner's use of a design consultant to develop
criteria documents before design-builder selection
EXPERT RATIONALE: Bridging involves the owner hiring a separate design
professional (criteria architect or engineer) to develop the project requirements,
performance criteria, and partial design documents. These are then used as the
, basis for design-build proposals, allowing the owner to define quality expectations
while still benefiting from design-build efficiency.
6. Which contract type places the greatest financial risk on the design-builder
for cost overruns?
A. Cost-plus with guaranteed maximum price
B. Time and materials contract
C. Lump sum (fixed price) contract
D. Cost-plus with a fee
E. Unit price contract
Correct Answer: C. Lump sum (fixed price) contract
EXPERT RATIONALE: Under a lump sum contract, the design-builder agrees to
deliver the project for a fixed price regardless of actual costs incurred. If costs
exceed the contract price, the design-builder absorbs the loss. This transfers
maximum cost risk to the design-builder and is most appropriate when the scope
of work is well-defined through owner-provided criteria documents.
7. In DBIA best practices, at what phase should the design-builder ideally be
selected to maximize project value?
A. After 100% design completion
B. During the construction administration phase
C. Early in project development, during or before schematic design
D. After the owner has obtained all permits
E. Only after the project site has been fully remediated
Correct Answer: C. Early in project development, during or before
schematic design
