SECTION 1: GUIDING PRINCIPLES & FOUNDATIONS OF DESIGN-BUILD
QUESTION 1
Which of the following is a fundamental concept that influences the move to
integration in design-build project delivery?
A. Cost-Influence curve
B. Benefits of fast tracking
C. Spearin Doctrine
D. All of the above
ANSWER: D
RATIONALE: Three fundamental concepts influence the move to integration in
design-build: the Cost-Influence curve (which shows that early decisions have
the greatest impact on project cost), the benefits of fast tracking (overlapping
design and construction activities), and the Spearin Doctrine (which establishes
owner liability for the accuracy of plans and specifications). These concepts
form the basis for why design-build is an effective project delivery method.
QUESTION 2
What does the Cost-Influence curve demonstrate in design-build project delivery?
A. Costs increase as the project progresses
B. Influence on project outcomes is highest in the planning phase
C. Construction costs are fixed at project inception
D. Design costs are the most significant project expense
ANSWER: B
RATIONALE: The Cost-Influence curve demonstrates that the ability to influence
project outcomes—including cost, schedule, and quality—is highest during the
1
,planning phase and decreases as the project moves through design and
construction.
This fundamental concept supports the design-build approach, where early
collaboration between designers and builders can optimize project outcomes.
QUESTION 3
What are the four phases of the Cost-Influence curve?
A. Planning, Design, Construction, Operations
B. Pre-design, Design, Bidding, Construction
C. Programming, Schematic Design, Design Development, Construction
D. Planning, Procurement, Construction, Closeout
ANSWER: A
RATIONALE: The four phases of the Cost-Influence curve are Planning, Design,
Construction, and Operations. The planning phase has the highest influence on
project outcomes, while the operations phase has the lowest. This demonstrates
the importance of making critical decisions early in the project lifecycle.
QUESTION 4
In which project delivery method is the construction team brought on AFTER
design is completed, with open bidding?
A. Design-Build
B. Design-Bid-Build (DBB)
C. Construction Manager at Risk (CMAR)
D. Integrated Project Delivery (IPD)
ANSWER: B
RATIONALE: Design-Bid-Build (DBB) is a linear sequential process where the
design is completed before the construction team is brought on board through
open bidding. This traditional delivery method is characterized by separate
contracts between the owner and the designer, and between the owner and the
contractor.

,QUESTION 5
In which project delivery method is the construction team brought on EARLY,
facilitating fast-tracking of the schedule?
A. Design-Bid-Build (DBB)
B. Design-Build (DB)
C. Construction Manager at Risk (CMAR)
D. Multiple Prime Contracting
ANSWER: B
RATIONALE: Design-Build (DB) brings the construction team on early in the
process, allowing for fast-tracking where design and construction activities
can overlap. This integration is one of the key advantages of design-build
project delivery and enables earlier project completion compared to traditional
methods.
QUESTION 6
What is the Spearin Doctrine?
A. A doctrine that establishes contractor liability for design errors
B. A doctrine that provides contractors with two implied warranties from the
owner
C. A doctrine that limits owner liability in construction contracts
D. A doctrine that requires competitive bidding for all public projects
ANSWER: B
RATIONALE: The Spearin Doctrine, established by the U.S. Supreme Court,
provides
contractors with two implied warranties from the owner: (1) that the plans and
specifications are accurate, and (2) that the plans and specifications are suitable
for their intended purpose. This doctrine is fundamental to understanding owner
liability in design-build and other project delivery methods.
QUESTION 7
What are the two implied warranties provided by the owner under the Spearin
3
, Doctrine?
A. Plans and specs are accurate; Plans and specs are suitable for intended purpose
B. Plans and specs are complete; Plans and specs are cost-effective
C. Plans and specs are buildable; Plans and specs are code-compliant
D. Plans and specs are current; Plans and specs are sustainable
ANSWER: A
RATIONALE: Under the Spearin Doctrine, the owner warrants that the plans and
specifications are accurate and suitable for their intended purpose. This means
the owner bears responsibility for design errors or omissions, and the contractor
is entitled to additional compensation for work performed as a result of such
errors.
QUESTION 8
What are the five types of project delivery systems recognized in design-build
practice?
A. DB, DBB, CMAR, IPD, Multiple Prime Contracting
B. DB, DBB, CM, EPC, PPP
C. DB, DBB, CMAR, EPC, PPP
D. DB, DBB, CMAR, IPD, EPC
ANSWER: A
RATIONALE: The five types of project delivery systems are Design-Build (DB),
Design-Bid-Build (DBB), Construction Manager at Risk (CMAR), Integrated Project
Delivery (IPD), and Multiple Prime Contracting. Each has unique characteristics,
advantages, and limitations that owners should consider when selecting a delivery
method.
QUESTION 9
Which project delivery method is described as a "linear sequential process"?
A. Design-Build
B. Design-Bid-Build
C. Construction Manager at Risk
