Question 1: In the context of design-build project delivery, which of the following
best describes the primary role of the "Bridging Documents" as defined by the
DBIA?
A. To serve as the final construction documents for the trade contractors.
B. To provide a conceptual design that is replaced entirely by the design-builder's
proposal.
C. To establish the performance criteria, programmatic requirements, and schematic
design to a level that allows for accurate and comparable proposals.
D. To act as the legal contract between the owner and the design-builder.
CORRECT ANSWER: C. To establish the performance criteria, programmatic
requirements, and schematic design to a level that allows for accurate and
comparable proposals.
Rationale: Bridging documents are a critical tool in design-build procurement. They are
developed by the owner and its consultants to a level of detail (typically 10-30% design)
that clearly defines the project's scope, quality, and performance requirements. This
provides a consistent baseline for all proposing design-build teams, ensuring that their
responses are comparable and meet the owner's minimum needs without dictating the
specific means and methods of construction, which is left to the design-builder's
innovation.
Question 2: Which fundamental characteristic distinguishes a design-build
contract from a Construction Manager at Risk (CMAR) contract?
A. The contractor is selected before the design is complete.
B. The single entity holds contracts for both design and construction services.
C. The owner retains the majority of the design risk.
D. The contract is always awarded based on the lowest bid price.
CORRECT ANSWER: B. The single entity holds contracts for both design and
construction services.
Rationale: The defining characteristic of design-build is the integration of design and
construction under a single contract with the owner. In CMAR, the owner holds separate
contracts for design and construction, even though the CM provides pre-construction
services. This single point of responsibility in design-build is the core mechanism for
,achieving project integration and reducing owner risk related to design-construction
coordination.
Question 3: In a design-build contract, what is the primary purpose of a "Stipulated
Sum" or "Lump Sum" pricing structure?
A. To allow for unlimited cost increases based on owner changes.
B. To reimburse the design-builder for all actual costs plus a fixed fee.
C. To provide a fixed, agreed-upon total price for the defined scope of work.
D. To establish a target cost with a shared savings incentive.
CORRECT ANSWER: C. To provide a fixed, agreed-upon total price for the defined
scope of work.
Rationale: A stipulated sum contract sets a fixed price for the entire project based on
the contract documents. This structure provides the owner with cost certainty upfront
and transfers the majority of the cost risk to the design-builder, who must manage its
costs to deliver the project within that fixed sum.
Question 4: The DBIA's "Design-Build Done Right®" philosophy is centered on which
core principle?
A. The principle of "lowest responsible bidder" for procurement.
B. The principle of "best value" selection and integrated project delivery.
C. The principle of separating design and construction to ensure checks and balances.
D. The principle of maximizing owner-directed changes during construction.
CORRECT ANSWER: B. The principle of "best value" selection and integrated
project delivery.
Rationale: "Design-Build Done Right®" is a set of best practices promoted by the DBIA.
At its heart is the concept of integrated project delivery and the selection of the design-
builder based on a "best value" criteria, which considers qualifications, past
performance, and technical approach alongside price, rather than solely on the lowest
bid. This fosters a collaborative environment focused on quality and project success.
Question 5: During the procurement phase of a public design-build project, what is
the most significant advantage of using a two-step selection process (e.g., Request
for Qualifications followed by a Request for Proposals)?
A. It ensures that the contract is awarded to the local contractor.
B. It allows the owner to evaluate the technical and financial capabilities of the
proposers before they invest significant resources in a full proposal.
,C. It is a faster process than a single-step Request for Proposals.
D. It legally mandates that price is the only selection criterion.
CORRECT ANSWER: B. It allows the owner to evaluate the technical and financial
capabilities of the proposers before they invest significant resources in a full
proposal.
Rationale: The two-step process is efficient and fair. The RFQ step pre-qualifies teams
based on their qualifications and past performance, ensuring that only capable teams
proceed to the RFP step. This prevents unqualified teams from spending time and
money on a detailed technical proposal and allows the owner to focus its evaluation on
a more qualified pool of competitors.
Question 6: From an owner's perspective, which of the following is a primary risk
associated with the design-build project delivery method?
A. The inability to initiate construction before the design is 100% complete.
B. The loss of direct control over the design details and the potential for the design-
builder to "value engineer" the project in ways that may not align with the owner's
desired quality or aesthetics.
C. The requirement to hold a separate contract with the architect.
D. A significantly longer project delivery schedule compared to Design-Bid-Build.
CORRECT ANSWER: B. The loss of direct control over the design details and the
potential for the design-builder to "value engineer" the project in ways that may not
align with the owner's desired quality or aesthetics.
Rationale: In design-build, the owner transfers control over the detailed design to the
design-builder. While this reduces the owner's management burden, it also introduces
the risk that the design-builder may make decisions during design development or value
engineering that prioritize cost savings over the owner's desired level of quality,
aesthetics, or functionality, especially if the performance criteria are not well-defined.
Question 7: What is the primary legal function of "flow-down clauses" in a design-
build subcontract?
A. To allow the subcontractor to bypass the design-builder and contract directly with the
owner.
B. To pass the terms, conditions, and obligations of the prime design-build contract
down to the subcontractor.
C. To provide a separate payment schedule for the subcontractor.
D. To eliminate all liability of the subcontractor for design errors.
CORRECT ANSWER: B. To pass the terms, conditions, and obligations of the prime
design-build contract down to the subcontractor.
, Rationale: Flow-down clauses are standard in construction subcontracts. They
incorporate by reference the prime contract's key provisions, such as warranty
requirements, dispute resolution procedures, and scope of work, into the subcontract.
This ensures that the subcontractor is bound by the same obligations that the design-
builder owes to the owner, creating a consistent chain of responsibility and risk.
Question 8: In the context of design-build, "Best Value" procurement is best
defined as:
A. The award of the contract to the proposer with the lowest total bid price.
B. The award based on a predetermined formula that evaluates cost, technical merit,
qualifications, and other relevant factors.
C. A process where the owner selects the design-build entity based solely on the
architect's reputation.
D. A method that prioritizes a fast-track schedule over all other selection criteria.
CORRECT ANSWER: B. The award based on a predetermined formula that evaluates
cost, technical merit, qualifications, and other relevant factors.
Rationale: Best Value is a sophisticated procurement approach that goes beyond a
simple low-bid analysis. It involves a weighted scoring system where the owner
evaluates proposals on a combination of criteria, such as price, proposed team, design
quality, schedule, and approach to project management. This allows the owner to
select the team that offers the overall optimum balance of cost and performance,
aligning with the project's strategic goals.
Question 9: What is the term for a contractual agreement where the design-
builder's profit is adjusted based on the final cost of the project relative to a target
cost?
A. Stipulated Sum Agreement
B. Cost Plus Fixed Fee Agreement
C. Guaranteed Maximum Price (GMP) Agreement
D. Incentive-Based Target Cost Agreement
CORRECT ANSWER: D. Incentive-Based Target Cost Agreement
Rationale: An incentive-based target cost agreement (often part of a GMP) establishes
a target cost for the project. If the final cost is below the target, the design-builder and
owner share in the savings, typically through a pre-agreed percentage. Conversely, if the
cost exceeds the target, the design-builder may be required to share in the overrun,
creating a powerful incentive for cost management and efficiency.
