DBIA Design-Build Certification — Questions and Answers

Question 1: The Brooks Act (40 U.S.C. §§ 1101–1104) mandates qualifications-based selection (QBS) for federal architect-engineer services contracts. When a federal civilian agency procures a design-build contract for a new headquarters facility under FAR Subpart 36.3, which statement most precisely reflects the legal relationship between the Brooks Act QBS requirement and the two-phase design-build selection procedure?

The Brooks Act applies only to the design-build team's A-E subconsultant, who must be selected by QBS before the prime design-builder is chosen
FAR Subpart 36.3 operates as a distinct statutory authority for design-build procurement; the contract is classified as a construction procurement, not an A-E services contract, so the Brooks Act QBS mandate does not govern the prime contract selection (Correct answer)
The Brooks Act applies to the entire design-build contract and overrides FAR Subpart 36.3, requiring QBS without price competition for the combined design-build award
Agencies must conduct a parallel Brooks Act QBS for design services and a FAR Part 36.3 competition for construction, then negotiate a combined contract with the firms selected through each respective process

Correct answer: FAR Subpart 36.3 operates as a distinct statutory authority for design-build procurement; the contract is classified as a construction procurement, not an A-E services contract, so the Brooks Act QBS mandate does not govern the prime contract selection

Under the FAR, a design-build contract for facilities construction is classified as a construction contract and procured under FAR Part 36, specifically Subpart 36.3 for the two-phase procedure. The Brooks Act QBS mandate (implemented in FAR Subpart 36.6) applies to acquisitions where the predominant purpose is architect-engineer services. Because the design-build contract's primary purpose is construction — with design integrated as a means to that end — it does not trigger the Brooks Act QBS requirement for the prime contractor selection. FAR 36.3 itself provides a qualifications-based Phase 1 process, but this is a procurement regulation, not a Brooks Act requirement. Critically, the Brooks Act does not require the design-builder's A-E subconsultant to be independently selected by QBS either; that decision is the design-builder's teaming choice.

Question 2: An owner is evaluating whether to use a single-phase or two-phase procurement approach for a design-build sports arena with complex acoustics, retractable roof systems, and a compressed 14-month schedule. Several nationally recognized design-build teams are likely to compete. Industry representatives warn the owner that requiring full technical proposals in a single phase will impose significant unreimbursed costs on teams. What is the STRONGEST argument for adopting a two-phase approach in this specific scenario?

A two-phase process shortlists only the most qualified teams before requiring costly technical proposals, reducing industry burden, improving proposal quality from finalists, and focusing the owner's evaluation resources on a manageable set of credible competitors. (Correct answer)
Single-phase procurement is never appropriate for projects with schedule constraints because it extends the overall timeline by at least 90 days compared to two-phase.
Two-phase procurement is required by law whenever a project exceeds $50 million in construction value.
A two-phase process eliminates the owner's obligation to pay stipends, reducing overall procurement costs for the owner.

Correct answer: A two-phase process shortlists only the most qualified teams before requiring costly technical proposals, reducing industry burden, improving proposal quality from finalists, and focusing the owner's evaluation resources on a manageable set of credible competitors.

The primary rationale for two-phase design-build procurement, as articulated in DBIA guidance and federal FAR 36.3 regulations, is to limit the expense of preparing detailed technical proposals to a shortlisted field of qualified competitors. For a complex, specialized project likely to attract strong national teams, requiring all comers to produce full technical submittals wastes industry resources, generates unmanageable evaluation workloads, and may actually deter top teams from competing. Two-phase procurement improves both fairness and proposal quality from finalists.

Question 3: An experienced PDB owner is evaluating whether to include a 'Phase 2 Right of First Negotiation' clause versus a 'Phase 2 Automatic Award' clause in their PDB contract for a hospital expansion. Which statement MOST accurately reflects the risk implications of these two approaches under DBIA guidance?

Automatic Award is preferred by DBIA for public owners because it reduces procurement risk and the appearance of favoritism in GMP negotiations
Automatic Award eliminates the owner's ability to re-procure if the GMP is unacceptable, undermining a core PDB risk-management feature, while Right of First Negotiation preserves competitive leverage without fully surrendering the owner's off-ramp (Correct answer)
Both clauses are functionally equivalent under DBIA model documents because the owner always retains the right to reject a non-conforming GMP regardless of Phase 2 award language
Right of First Negotiation creates a contractual obligation to accept any GMP within 15% of the owner's budget, whereas Automatic Award gives the owner full discretion to reject the GMP for any reason

Correct answer: Automatic Award eliminates the owner's ability to re-procure if the GMP is unacceptable, undermining a core PDB risk-management feature, while Right of First Negotiation preserves competitive leverage without fully surrendering the owner's off-ramp

This is a nuanced PDB contract structuring issue. Automatic Award of Phase 2 to the Phase 1 design-builder, regardless of GMP acceptability, removes the owner's fundamental off-ramp — the ability to terminate for convenience and re-procure using Phase 1 documents. This off-ramp is what gives the owner leverage during GMP negotiations and is a defining risk-management feature of PDB. A Right of First Negotiation preserves the collaborative relationship and gives the Phase 1 team priority to negotiate Phase 2, while still allowing the owner to walk away if negotiations fail. DBIA guidance consistently supports owner retention of the re-procurement right. The other options misstate DBIA positions and create fictional contract mechanics.

Question 4: In a Progressive Design-Build contract, what typically triggers the formal transition from Phase 1 (preconstruction) to Phase 2 (construction)?

Owner's unilateral decision to proceed without GMP agreement
Issuance of a certificate of occupancy by the local authority
Completion of 50% of construction documents by the architect of record
Mutual agreement on and execution of the Guaranteed Maximum Price amendment (Correct answer)

Correct answer: Mutual agreement on and execution of the Guaranteed Maximum Price amendment

The GMP amendment, mutually agreed upon and executed by both parties, formally transitions the project from preconstruction collaboration to construction execution.

Question 5: A public agency is using Progressive Design-Build for a complex wastewater treatment plant. They have selected a design-build team and are currently in Phase 1. Which of the following activities is the primary focus for the integrated owner and design-build team during this phase?

Mobilizing construction equipment and beginning site excavation.
Collaboratively advancing the design, defining scope, and performing value engineering. (Correct answer)
Submitting a firm, fixed price for the entire project.
Finalizing subcontractor agreements for all major trades.

Correct answer: Collaboratively advancing the design, defining scope, and performing value engineering.

Phase 1 of Progressive Design-Build is dedicated to pre-construction services. The core activity is the collaborative effort between the owner and the design-builder to develop the project's design, validate the scope, identify risks, conduct value engineering, and progressively develop cost estimates. This sets the foundation for establishing the GMP for Phase 2.

Question 6: What procurement document is MOST commonly used to select a design-build team in a Progressive Design-Build procurement?

Request for Information (RFI) to clarify existing construction documents
Invitation for Bid (IFB) requiring a fixed lump-sum price
Notice to Proceed (NTP) issued directly without competitive selection
Request for Qualifications (RFQ) or combined RFQ/RFP focused on team qualifications and approach (Correct answer)

Correct answer: Request for Qualifications (RFQ) or combined RFQ/RFP focused on team qualifications and approach

PDB procurement typically uses an RFQ or RFQ/RFP process focused on qualifications, past performance, and project approach rather than fixed price.

Question 7: In a design-build project, which type of insurance specifically covers claims arising from errors or omissions in the design professional's services?

Workers' Compensation insurance
Commercial General Liability (CGL) insurance
Builder's Risk insurance
Professional Liability (Errors & Omissions) insurance (Correct answer)

Correct answer: Professional Liability (Errors & Omissions) insurance

Professional Liability (E&O) insurance covers claims resulting from negligent acts, errors, or omissions in professional design services. CGL covers bodily injury and property damage but explicitly excludes professional services. Builder's Risk covers physical damage to the structure during construction, and Workers' Comp covers employee injuries.

Question 8: An owner is considering Progressive Design-Build for a complex biomedical research facility. A key program requirement will not be finalized until 14 months into the project. Which Phase 1 strategy best aligns with PDB's collaborative framework while protecting the owner's budget certainty?

Delay the Phase 1 start until all program requirements are fully defined to avoid scope changes that undermine the GMP.
Structure Phase 1 with a base scope GMP for known requirements and a separately priced contingency allowance with defined triggers for the undefined programmatic element. (Correct answer)
Proceed with Phase 1, use a bridging architect to develop a fixed program, and require the design-builder to assume all scope risk associated with the undefined requirement.
Issue a traditional fixed-price design-build RFP once the program is finalized, as PDB's value is negated when program definition is delayed beyond 12 months.

Correct answer: Structure Phase 1 with a base scope GMP for known requirements and a separately priced contingency allowance with defined triggers for the undefined programmatic element.

Progressive Design-Build is specifically suited to projects with evolving scope. The correct approach is to establish a GMP for the known base scope while creating a structured allowance with defined triggers for the undefined requirement. This preserves PDB's collaborative advantage — open-book pricing, early contractor involvement — while giving the owner budget discipline. Option A defeats PDB's purpose (early engagement). Option B improperly shifts all risk to the design-builder without compensation, which is unfair and will inflate contingency pricing. Option D incorrectly asserts a 12-month rule that does not exist; PDB is often preferred precisely in these ambiguous program scenarios.

Question 9: During commissioning of a complex HVAC system on a design-build laboratory project, the system fails to achieve the specified air change rates under a simultaneous full-occupancy load test. The design-builder's mechanical engineer demonstrates through computational fluid dynamics modeling that the specified load scenario exceeds the thermodynamic capacity implied by the owner's performance specification, arguing the spec was physically unachievable as written. Independent testing confirms the CFD analysis. Under design-build risk allocation principles, what is the most appropriate resolution framework?

The owner is solely responsible because performance specifications shift all design risk, including feasibility verification, to the owner's technical staff.
The design-builder bears full liability because design-build contracts transfer the duty to achieve performance outcomes regardless of specification ambiguity.
If the performance specification was genuinely unachievable as written and the design-builder exercised reasonable professional judgment in designing to it, the resolution likely involves shared responsibility — with the design-builder potentially liable for not identifying the infeasibility earlier during design, and the owner liable for issuing an unachievable specification. (Correct answer)
The commissioning test is automatically waived when independent analysis confirms specification infeasibility, and the design-builder receives full final payment without further performance testing.

Correct answer: If the performance specification was genuinely unachievable as written and the design-builder exercised reasonable professional judgment in designing to it, the resolution likely involves shared responsibility — with the design-builder potentially liable for not identifying the infeasibility earlier during design, and the owner liable for issuing an unachievable specification.

Design-build risk allocation for performance specifications is nuanced. While performance specs shift design solution risk to the design-builder, they do not relieve owners of responsibility for establishing achievable performance criteria. However, design-builders have a professional duty to flag specification conflicts or physical impossibilities during design development — not at commissioning. DBIA risk allocation guidance recognizes that when a spec is unachievable and the design-builder failed to raise the issue during design review, responsibility is typically shared: the owner for issuing a defective specification, the design-builder for delayed identification. Pure 'all-or-nothing' outcomes are rarely appropriate.

Question 10: A design-builder is closing out a project where the owner requires a Leadership in Energy and Environmental Design (LEED) certification under the contract. At Substantial Completion, the final review by the certifying body is still pending and an unresolved credit could drop the certification level. Which contractual treatment is MOST consistent with sound design-build risk allocation?

The owner should assume all certification risk since the owner controls building operations after turnover
The contract should define whether the obligation is to achieve a specified certification or to pursue it with documented diligence, and tie any liquidated damages or holdbacks to that defined obligation and a post-completion review window (Correct answer)
The design-builder is automatically responsible for any lost credits regardless of what the contract states
Certification level becomes a Substantial Completion condition, even though the review timeline is controlled by a third party

Correct answer: The contract should define whether the obligation is to achieve a specified certification or to pursue it with documented diligence, and tie any liquidated damages or holdbacks to that defined obligation and a post-completion review window

Third-party certification timing is outside either party's control, and some credits depend on owner operations. Sound allocation clearly defines whether the design-builder must achieve or merely pursue certification, separates this from Substantial Completion where appropriate, and provides a defined post-completion review window with matching remedies. Automatic liability or complete transfer to the owner ignores shared control.

Question 11: When a port authority uses design-build to expand container terminal capacity, which technical specialty is most critical to integrate early in design?

HVAC engineering
Landscape architecture
Geostructural and marine civil engineering (Correct answer)
Interior design

Correct answer: Geostructural and marine civil engineering

Marine and geostructural engineers must evaluate soil conditions, wave loads, and pile design early because these factors drive major cost and schedule decisions.

Question 12: In a design-build project, when an owner issues a 'Request for Information' (RFI) to the design-builder, it differs from traditional RFIs because:

The owner must pay a fee for each RFI response
RFIs automatically trigger change orders in design-build
The design-builder must resolve the issue internally rather than routing it to a separate design team (Correct answer)
RFIs do not exist in design-build contracts

Correct answer: The design-builder must resolve the issue internally rather than routing it to a separate design team

Since the design-builder is responsible for both design and construction, they resolve most coordination issues internally without needing the owner to mediate between separate designer and contractor parties.

Question 13: Which phase of the Progressive Design-Build process involves the team refining cost estimates as design progresses from conceptual to schematic?

Punch-list and closeout phase
Commissioning and systems startup phase
Preconstruction/design development phase (Correct answer)
Post-occupancy evaluation phase

Correct answer: Preconstruction/design development phase

The preconstruction/design development phase is when the design-build team progressively refines cost estimates as design moves from concept through schematic levels.

Question 14: On a design-build transit project, the project controls team identifies that the Critical Path has shifted three times in six weeks due to utility relocation delays. The original float analysis is no longer valid. Which project controls technique BEST supports schedule recovery analysis in this scenario while preserving contractual defensibility for delay claims?

Time Impact Analysis (TIA) applied prospectively to each delay event as it occurs, with contemporaneous fragnet insertion into the updated baseline schedule (Correct answer)
Retrospective Total Float Erosion Analysis applied at project completion to quantify cumulative owner-caused delays in a single consolidated claim
Replacement of the CPM schedule with a linear scheduling method to better visualize repetitive utility relocation work and eliminate float ambiguity
Global acceleration of all remaining critical and near-critical activities using mandatory overtime, with schedule compression documented in the monthly owner report

Correct answer: Time Impact Analysis (TIA) applied prospectively to each delay event as it occurs, with contemporaneous fragnet insertion into the updated baseline schedule

Time Impact Analysis (TIA) with prospective fragnet insertion is the DBIA-aligned standard for documenting delay impacts in real time. Each delay event is analyzed as it occurs by inserting a fragnet (a small sub-network representing the delay) into the current update of the approved baseline schedule, quantifying float consumption and critical path shift. This creates a contemporaneous record that is defensible in disputes and satisfies most public and private owner contract requirements. Blanket acceleration without analysis creates cost exposure, retrospective consolidation loses contemporaneous credibility, and switching scheduling methods mid-project introduces baseline integrity problems.

Question 15: During a design-build pursuit, a firm's BD director coaches technical staff to reference a completed hospital project in their qualifications package, knowing the firm's actual role was limited to MEP design only—not the full design-build delivery the proposal implies. The director argues that 'the owner will ask clarifying questions if they want detail.' How does the DBIA Code treat this situation?

It is a violation because misrepresenting the scope of prior experience in qualifications constitutes a false statement of professional competence, regardless of whether the owner asks follow-up questions. (Correct answer)
It is only a violation if the owner can demonstrate they were materially harmed by the misrepresentation after award.
It is permissible marketing practice as long as the firm can perform the full scope if awarded the project.
It is permissible if a footnote elsewhere in the package clarifies the firm's limited role on that project.

Correct answer: It is a violation because misrepresenting the scope of prior experience in qualifications constitutes a false statement of professional competence, regardless of whether the owner asks follow-up questions.

The DBIA Code prohibits false or misleading statements about professional qualifications and experience. Implying full design-build delivery experience when the firm's role was limited to one discipline misrepresents competency. The burden does not fall on the owner to extract truth through follow-up questions; the ethical obligation is affirmative and proactive. Harm to the owner is not a prerequisite for a Code violation.

Question 16: Which of the following sustainability strategies is most effectively deployed in a design-build project during the pre-design phase?

Issuance of LEED certification by the U.S. Green Building Council
Punch list completion and commissioning of energy systems
Retainage release conditioned on energy performance metering
Integrated passive design strategies such as building orientation, massing, and daylighting (Correct answer)

Correct answer: Integrated passive design strategies such as building orientation, massing, and daylighting

Passive design strategies—orientation to minimize solar heat gain, building massing for natural ventilation, and daylighting optimization—must be established during pre-design and schematic design. These decisions are difficult or impossible to change later. Design-build's early designer-builder collaboration makes pre-design the ideal phase to lock in high-impact passive strategies.

Question 17: What is the role of the 'design manager' in a design-build organization?

The design manager only reviews shop drawings
The design manager coordinates all design disciplines, manages the design schedule, ensures design quality, and interfaces between design and construction teams (Correct answer)
The design manager handles only administrative tasks
The design manager replaces the architect of record

Correct answer: The design manager coordinates all design disciplines, manages the design schedule, ensures design quality, and interfaces between design and construction teams

The design manager is a critical leadership role coordinating multidisciplinary design and ensuring integration between design and construction.

Question 18: A public agency uses a bridging consultant to develop 35% design documents for a design-build RFP. The geotechnical report embedded in those documents contains a disclaimer stating the data is 'provided for reference only and does not relieve the design-builder of independent investigation obligations.' The successful design-builder later encounters Type II differing site conditions not inferable from the reference data. Which statement BEST reflects the owner's residual liability under DBIA risk allocation doctrine?

The disclaimer fully and unambiguously transfers all geotechnical risk to the design-builder upon contract execution
The design-builder assumes unconditional site risk in design-build contracts as a fundamental feature of the delivery model
The owner retains liability for materially inaccurate or misleading owner-provided information even when disclaimers are present, though the design-builder must conduct proportionate independent verification (Correct answer)
The bridging consultant bears sole liability as the originator of the geotechnical data, relieving both owner and design-builder

Correct answer: The owner retains liability for materially inaccurate or misleading owner-provided information even when disclaimers are present, though the design-builder must conduct proportionate independent verification

DBIA guidance and case law recognize that boilerplate disclaimers do not extinguish the owner's duty of good faith disclosure of material site information. If the owner-provided data is materially inaccurate or incomplete, the owner retains exposure regardless of the disclaimer language. However, the design-builder also has a proportionate duty to perform independent investigation consistent with the contract's technical standards — so responsibility is conditioned, not eliminated, on both sides.

Question 19: A design-build RFP for a complex water treatment plant includes a price proposal requirement structured as a lump-sum base bid plus separate unit prices for six specified scope contingencies. During proposal evaluation, the selection committee discovers that one proposer intentionally priced the unit rates at near-zero values, anticipating that those contingencies would be triggered and the low unit prices would advantage them in post-award change order negotiations. This practice is known as what, and what is the owner's most effective RFP mechanism to prevent it?

Contingency arbitrage; prevented by requiring a sealed separate envelope for unit prices that is opened only after technical scoring is complete.
Unbalanced bidding; prevented by reserving the right to reject proposals where unit prices are mathematically or materially unbalanced relative to estimated quantities. (Correct answer)
Price loading; prevented by requiring proposers to certify that all unit rates reflect actual anticipated costs under penalty of proposal rejection.
Price shadowing; prevented by capping unit prices at the owner's independent cost estimate for each contingency item.

Correct answer: Unbalanced bidding; prevented by reserving the right to reject proposals where unit prices are mathematically or materially unbalanced relative to estimated quantities.

Deliberately distorting unit prices—whether front-loading or, as here, rear-loading to gain post-award advantage—is the classic definition of unbalanced bidding. DBIA and FAR-based procurement guidance both permit owners to reject proposals that are materially unbalanced, meaning the distortion introduces risk of overpayment or unfair competitive advantage. Answer A (price loading) is a real concept but refers to front-loading, not understating future unit rates. Answer C invents a term and a procedural remedy that does not address the underlying distortion. Answer D (capping at ICE) is one mitigation but is not the standard definitional remedy—the owner's right to reject unbalanced bids is the primary tool recognized in procurement law and DBIA practice.

Question 20: What is the significance of the 'concept of sufficient design' in establishing the GMP in Progressive Design-Build?

It is a legal standard for determining when the design-build team's liability begins
It means the design has reached a level of completeness that supports a reliable, defensible cost estimate for GMP agreement (Correct answer)
Sufficient design indicates all construction documents are 100% complete and permitted
It refers to the minimum design quality acceptable for occupancy permit issuance

Correct answer: It means the design has reached a level of completeness that supports a reliable, defensible cost estimate for GMP agreement

Sufficient design means enough design detail exists to allow the team and owner to agree on a reliable GMP, even if full construction documents are not yet complete.

Question 21: Progressive Design-Build is considered particularly effective for which type of project condition?

Projects that legally mandate competitive sealed bidding processes
Projects with fully defined scope, detailed drawings, and established budgets
Projects with evolving or complex programs where early owner-team collaboration adds value (Correct answer)
Projects requiring the fastest possible procurement with minimal owner engagement

Correct answer: Projects with evolving or complex programs where early owner-team collaboration adds value

PDB excels when project scope is complex or evolving, because the collaborative structure allows requirements to be refined before cost is fixed.

Question 22: In design-build project execution, 'constructability review' is BEST described as:

A financial audit of subcontractor bids
A safety inspection conducted by a third-party authority
An evaluation of design documents to identify construction challenges and optimize methods (Correct answer)
A legal review of the construction contract for enforceability

Correct answer: An evaluation of design documents to identify construction challenges and optimize methods

Constructability review integrates construction expertise into the design process to identify and resolve issues that could impede efficient field execution.

Question 23: A design-build team is in the progressive design-build procurement phase and the owner requests a Guaranteed Maximum Price (GMP) before design reaches 30% completion. Which risk allocation consideration is most critical for the design-builder at this stage?

The design-builder must include an allowance contingency sized to cover unknown design development costs, and the contract should specify how unused contingency is shared (Correct answer)
A GMP at sub-30% design is inherently unfair and shifts all design development risk to the owner
The design-builder should refuse the GMP until design reaches 60% because DBIA guidelines prohibit early pricing
The design-builder should propose a cost-plus contract with a fixed fee instead to avoid premature commitment

Correct answer: The design-builder must include an allowance contingency sized to cover unknown design development costs, and the contract should specify how unused contingency is shared

In progressive design-build, an early GMP is common but requires robust contingency structuring. The design-builder must include sufficient design development allowances and contingencies to cover unknowns that will emerge as design advances. Critically, the contract should specify the mechanism for shared savings if the contingency is not consumed — this aligns owner and design-builder incentives. DBIA guidelines do not prohibit early GMP; they advise appropriate risk allocation tools like shared savings provisions and clearly defined scope assumptions.

Question 24: A DBIA-member design-build team is value-engineering a federal courthouse project subject to the FAR (Federal Acquisition Regulations). They identify a VECP that would save $3.2M. Under FAR 52.248-3, the government's collateral savings are estimated at $800,000. What is the design-builder's maximum allowable share of total savings under the standard FAR VECP clause?

100% of savings up to the GMP, with the government retaining all savings exceeding the GMP
The design-builder receives no share of savings on federal projects because VECPs on FAR contracts transfer all savings to the government as a matter of public policy
50% of all savings including both instant contract savings and collateral savings with no cap
55% of the net acquisition savings (instant contract savings minus government costs to implement), plus 25% of collateral savings, subject to the contract's specific sharing rates, but the collateral savings share is typically capped (Correct answer)

Correct answer: 55% of the net acquisition savings (instant contract savings minus government costs to implement), plus 25% of collateral savings, subject to the contract's specific sharing rates, but the collateral savings share is typically capped

FAR 52.248-3 (Value Engineering—Construction) establishes a structured sharing formula. The contractor shares in 'instant contract savings' (direct cost reduction on the current contract) typically at rates up to 55%, and shares in 'collateral savings' (future government savings from the improvement) typically at 25%, with the collateral savings share often capped at the greater of $100,000 or the contract's target cost savings. This dual-component formula with caps is a distinctive feature of federal VECP rules that DBIA practitioners must understand when operating in the federal market.

Question 25: Which of the following is a common legislative barrier to implementing design-build?

Lack of interest among contractors
State-imposed restrictions on the use of design-build (Correct answer)
Overuse of integrated project delivery (IPD) methods
Excessive competition among design-build teams

Correct answer: State-imposed restrictions on the use of design-build

A significant legislative barrier to design-build implementation often comes from state laws that limit or prohibit its use for certain public projects. Many states have procurement statutes that traditionally favor design-bid-build, requiring legislative changes to allow for design-build. DBIA actively works to overcome these restrictions to expand design-build opportunities.

Question 26: Which technique BEST reduces design-to-construction coordination errors on complex design-build projects?

Relying on field personnel to identify and resolve all coordination issues during construction
Requiring all design to be 100% complete before any construction begins
Assigning separate teams for design and construction with minimal interaction
Using Building Information Modeling (BIM) with clash detection across disciplines (Correct answer)

Correct answer: Using Building Information Modeling (BIM) with clash detection across disciplines

BIM with clash detection identifies spatial conflicts between systems (structural, mechanical, electrical, etc.) during design, preventing costly field conflicts.

Question 27: According to DBIA's Universal Design-Build Best Practices, what is the recommended maximum number of design-build teams an owner should shortlist to submit proposals in Phase 2 of a best value procurement?

Three (Correct answer)
Five
There is no recommended limit.
Two

Correct answer: Three

DBIA best practices recommend shortlisting a maximum of three design-build teams to submit proposals in the second phase. This practice provides robust competition while respecting the significant time and expense proposers incur, and it allows the owner's evaluation team to focus on the best-qualified teams.

Question 28: Which of the following is a key advantage of the design-build delivery method over design-bid-build for owners?

Easier to change contract scope mid-project
Lower design fees due to competition
Greater owner control over design details
Single point of responsibility for design and construction (Correct answer)

Correct answer: Single point of responsibility for design and construction

Design-build consolidates design and construction responsibility under one entity, eliminating the finger-pointing that can occur between separate designers and contractors.

Question 29: During design development, a design-build team's value-engineering proposal would substitute a lower-cost insulation with a higher global warming potential (GWP) blowing agent, saving $140,000 but jeopardizing an EPD-based LEED materials credit and the owner's contractual embodied-carbon reduction target of 20% below baseline. What is the most appropriate process step under a sustainability-aligned design-build approach?

Substitute the product quietly and offset the lost credit later through unrelated operational measures
Reject all value-engineering proposals on the project to protect sustainability goals
Accept the substitution immediately because cost savings always take precedence over sustainability goals
Evaluate the proposal against the owner's project criteria using life-cycle cost and carbon impact, present the tradeoffs transparently, and obtain owner approval before changing a requirement tied to contractual targets (Correct answer)

Correct answer: Evaluate the proposal against the owner's project criteria using life-cycle cost and carbon impact, present the tradeoffs transparently, and obtain owner approval before changing a requirement tied to contractual targets

Because the embodied-carbon target is a contractual criterion, deviating from it requires transparent analysis and owner approval. Design-build's collaborative nature supports evaluating life-cycle cost and carbon tradeoffs rather than making unilateral or blanket decisions.

Question 30: How does the design-build delivery method typically reduce the frequency of disputes compared to traditional design-bid-build?

By eliminating the need for written contracts
By removing the gap between design intent and constructibility that often leads to disputes in traditional delivery (Correct answer)
By mandating government arbitration for all disputes
By requiring owners to assume all project risks

Correct answer: By removing the gap between design intent and constructibility that often leads to disputes in traditional delivery

Design-build eliminates the design-construction interface gap common in design-bid-build, reducing disputes about design intent, interpretation, and constructibility issues.

Question 31: What is a Guaranteed Maximum Price (GMP) in the context of design-build delivery?

A minimum price guarantee for subcontractors
A contract ceiling beyond which the owner does not pay cost overruns (Correct answer)
A fixed fee paid to the designer regardless of scope
The lowest possible bid a design-builder can offer

Correct answer: A contract ceiling beyond which the owner does not pay cost overruns

A GMP establishes an upper cost limit, protecting the owner from overruns while allowing savings to be shared if the project comes in under budget.

Question 32: During the claims management process on a DBIA design-build project, the parties disagree about the base schedule from which delay damages are to be measured. The design-builder claims entitlement based on its as-planned schedule, while the owner contends the project was already behind schedule through design-builder fault before the owner-caused delays began. Which forensic scheduling methodology is specifically suited to isolate concurrent delay and apportion responsibility in this scenario?

Collapsed as-built analysis, which reconstructs the as-built schedule by removing all excusable delay events to determine what the completion date would have been.
Time-impact analysis (TIA) applied prospectively from the contract baseline, which disregards pre-impact schedule status.
Window analysis (also known as contemporaneous period analysis), which segments the project into time windows to evaluate schedule status, causation, and concurrent delay within each discrete period. (Correct answer)
Global impact analysis, which aggregates all delay events and assigns a single percentage responsibility to each party without period-by-period evaluation.

Correct answer: Window analysis (also known as contemporaneous period analysis), which segments the project into time windows to evaluate schedule status, causation, and concurrent delay within each discrete period.

Window analysis divides the project timeline into discrete periods and evaluates the critical path, schedule float, and delay causation within each window. This methodology is especially powerful when there are allegations of pre-existing contractor delay and subsequent owner-caused delays, because it allows period-by-period apportionment and identification of true concurrent delay versus sequential delays with identifiable responsible parties. TIA is prospective and does not account for pre-existing delays. Collapsed as-built analysis focuses on removal of excusable events. Global impact analysis is generally disfavored for its inability to isolate concurrent causation.

Question 33: An owner wants to transfer the risk of design errors in the structural system entirely to the design-builder, but also insists on retaining the right to approve all structural engineering decisions throughout the project. Under DBIA risk allocation principles, this arrangement is problematic primarily because:

DBIA contracts prohibit owner approval rights over structural engineering as a matter of public safety policy
Structural risk can only be transferred to the design-builder when a Performance Specification, not a Prescriptive Specification, is used
Retaining approval authority over design decisions creates owner-directed design, potentially shifting liability for design errors back to the owner despite the contractual transfer (Correct answer)
The design-builder's professional liability insurer will automatically void coverage whenever an owner exercises any design approval right

Correct answer: Retaining approval authority over design decisions creates owner-directed design, potentially shifting liability for design errors back to the owner despite the contractual transfer

DBIA principles warn against the mismatch between risk transfer and control retention. When an owner contractually transfers design liability to the design-builder but simultaneously retains meaningful decision-making authority over design choices, courts and arbitrators may find that the owner's control over those decisions shifts the corresponding liability back to the owner. This is sometimes called the 'spearin-analog' problem in design-build: you cannot effectively transfer risk for decisions you are directing. The design-builder's single-point responsibility requires commensurate design authority.

Question 34: What is the primary purpose of the validation phase in Progressive Design-Build?

To allow the owner to review and refine the project program and confirm alignment before major cost commitment (Correct answer)
To formally accept the completed building from the design-build team
To finalize punch-list items before project closeout
To conduct post-occupancy evaluation of building performance

Correct answer: To allow the owner to review and refine the project program and confirm alignment before major cost commitment

The validation phase lets the owner refine project requirements and align expectations with the design-build team before committing to a price.

Question 35: During a progressive design-build project, the owner's representative begins attending all internal design-builder coordination meetings without prior agreement. The lead designer argues this compromises the integrated team's ability to self-organize. What is the MOST defensible position under DBIA principles?

The teaming agreement and project execution plan should define owner participation protocols; attendance without agreed-upon protocols can undermine psychological safety and integrated decision-making. (Correct answer)
The issue should be immediately escalated to dispute resolution because unauthorized meeting attendance constitutes a contract breach.
The owner has an inherent right to observe all project meetings as the contracting authority, regardless of team impact.
The lead designer's objection is unwarranted because transparency is a core design-build value that supersedes team autonomy.

Correct answer: The teaming agreement and project execution plan should define owner participation protocols; attendance without agreed-upon protocols can undermine psychological safety and integrated decision-making.

DBIA principles emphasize that the Project Execution Plan (PEP) and teaming agreements should explicitly define stakeholder participation in team meetings. While transparency is valued, unstructured owner participation in internal coordination meetings can inhibit candid problem-solving and undermine the integrated team's self-governance. Escalating to formal dispute resolution would be premature; the correct first step is referencing the agreed-upon collaboration protocols.

Question 36: A design-build team is 60% through construction when a new seismic code amendment takes effect in the jurisdiction. The contract stipulates that the design-builder must comply with 'all applicable codes and regulations in effect at the time of permit issuance.' The building permit was issued before the amendment. Which analysis best reflects proper contract interpretation under DBIA standards?

The design-builder is not required to incorporate the new amendment because the contract fixes compliance obligations to the code in effect at permit issuance, and a change order would be required if the owner directs compliance with the new amendment (Correct answer)
The design-builder must comply with the new amendment only for work not yet constructed, with no change order entitlement, because partial compliance is an implied contract obligation
The jurisdictional authority's adoption of the amendment automatically voids the existing permit, requiring the design-builder to pull a new permit and absorb all associated costs
The design-builder must retrofit completed work to meet the new amendment at their own cost, because design-build single responsibility includes ongoing code compliance throughout construction

Correct answer: The design-builder is not required to incorporate the new amendment because the contract fixes compliance obligations to the code in effect at permit issuance, and a change order would be required if the owner directs compliance with the new amendment

The contract language explicitly anchors compliance to codes 'in effect at the time of permit issuance.' The new amendment post-dates the permit; therefore, it represents a change in applicable law beyond the design-builder's contracted scope. If the owner directs compliance with the new amendment, it constitutes a change in scope entitling the design-builder to a change order for both completed and future work impacted. The design-builder is not obligated to absorb costs from regulatory changes that occur after the compliance baseline was established.

Question 37: An owner is considering Progressive Design-Build for a complex laboratory facility with highly specialized MEP requirements, but faces pressure from their procurement office to use the method primarily because it avoids competitive bidding on construction cost. Which statement BEST characterizes this rationale's alignment with PDB principles?

It is fully aligned — avoiding competitive bidding is a primary intended benefit of the PDB delivery method
It is misaligned — PDB is prohibited on projects where competitive bidding statutes apply to the owner
It is partially aligned — PDB eliminates competition entirely at project inception but introduces it at project closeout
It is misaligned — PDB still requires open-book estimating and market testing of subcontractor packages, so it does not eliminate competitive pricing (Correct answer)

Correct answer: It is misaligned — PDB still requires open-book estimating and market testing of subcontractor packages, so it does not eliminate competitive pricing

Progressive Design-Build does not eliminate competitive pricing — it defers and restructures it. Under DBIA best practices, Phase 2 GMP development relies on open-book estimating, competitive subcontractor buyout, and transparent cost reconciliation. The selection advantage is qualifications-based team integration during design, not circumventing market pricing. An owner proceeding under the false assumption that PDB avoids competitive subcontractor bids will likely face audit and governance problems.

Question 38: What is the primary responsibility of owners in a design-build project?

Managing day-to-day construction operations
Allowing the design-build team to determine the project scope
Defining clear project goals and priorities upfront (Correct answer)
Delegating all decision-making to the design-builder

Correct answer: Defining clear project goals and priorities upfront

In a design-build project, the owner's primary responsibility is to clearly articulate their project goals, objectives, and priorities from the outset. This foundational step ensures the design-build team fully understands the owner's vision and can develop a design and construction plan that aligns precisely with those expectations. Clear goals are crucial for successful project delivery.

Question 39: Which federal agency published the rule codifying design-build procedures at 48 CFR Part 36?

Office of Management and Budget (OMB)
Department of Transportation
Federal Acquisition Regulatory Council (Correct answer)
General Services Administration (GSA)

Correct answer: Federal Acquisition Regulatory Council

The Federal Acquisition Regulatory Council published the FAR rule incorporating design-build procedures into Part 36, which governs construction contracting.

Question 40: Following a major natural disaster, a public agency must immediately begin stabilization and repair work on critical infrastructure. The full extent of the damage is unknown and cannot be assessed until work is underway. In this emergency scenario, which design-build contracting approach would be most suitable to start the work quickly?

A Progressive Design-Build contract with a 90-day period for GMP development.
A Cost-Plus (Cost-Reimbursable) contract. (Correct answer)
A stipulated Lump Sum contract based on historical data.
A competitive low-bid procurement for a fixed-price contract.

Correct answer: A Cost-Plus (Cost-Reimbursable) contract.

A Cost-Plus contract allows work to begin immediately when the scope is undefined and risks are high. The owner agrees to pay the design-builder for the actual costs of the work plus a fee. This approach provides maximum flexibility to address the unknown conditions inherent in an emergency repair project where speed is the top priority.

Question 41: Which project delivery characteristic is shared between design-build and Integrated Project Delivery (IPD)?

Owner retains separate design and construction contracts
Competitive low-bid selection of trade contractors
Single-entity contractual responsibility
Multi-party risk-sharing through a relational contract (Correct answer)

Correct answer: Multi-party risk-sharing through a relational contract

Both DB and IPD emphasize early collaboration and shared risk/reward, though IPD uses a multi-party agreement rather than a single DB entity.

Question 42: How does design-build typically affect project delivery timelines compared to design-bid-build?

Design-build always takes longer due to added coordination
There is no difference in timeline between the methods
Design-build is faster only for projects under $1 million
Design-build compresses schedules by overlapping design and construction phases (Correct answer)

Correct answer: Design-build compresses schedules by overlapping design and construction phases

Design-build enables fast-tracking through concurrent design and construction activities, often reducing overall delivery time by 30-40%.

Question 43: A design-build team is mid-construction when the owner requests a significant scope change that the design team estimates will require 6 weeks of redesign. The construction team argues they can begin preparatory work using assumptions to avoid schedule slippage. The integration manager must decide how to proceed. Which approach BEST reflects advanced integrated team principles while managing risk?

Request a time extension equal to the 6-week redesign period and suspend affected construction activities until redesign is complete.
Begin all construction activities immediately using the team's best assumptions, since schedule is a primary design-build value proposition.
Halt all work pending a fully executed change order to protect the design-builder's contractual position.
Use a phased approach: identify work that can proceed without design resolution, define clear assumption boundaries with the owner's documented acknowledgment, and establish a concurrent redesign fast-track with defined decision gates. (Correct answer)

Correct answer: Use a phased approach: identify work that can proceed without design resolution, define clear assumption boundaries with the owner's documented acknowledgment, and establish a concurrent redesign fast-track with defined decision gates.

Advanced integrated team management under DBIA principles recognizes that the design-build advantage lies in concurrent activities and integrated problem-solving. The optimal approach segments work into what can safely proceed versus what is design-dependent, secures the owner's documented acknowledgment of proceeding under assumptions (managing risk), and implements a concurrent fast-track redesign process with defined decision gates. A full work stoppage forfeits the integrated team's core advantage; proceeding entirely on assumptions without documentation exposes the team to unquantified risk.

Question 44: During execution of a design-build water treatment facility, the design-builder's quality management plan (QMP) requires third-party commissioning verification for all process equipment. The owner's Designated Representative (ODR) begins attending and directing the design-builder's internal quality control inspections, issuing corrections directly to subcontractors and requesting changes to the QMP's inspection hold points. Under DBIA's execution framework, what is the primary risk this owner behavior creates?

It undermines the single-point-responsibility principle by blurring accountability lines, potentially giving the design-builder a defense against quality deficiency claims and exposing the owner to claims for owner-caused delays. (Correct answer)
It exposes the owner to Spearin Doctrine liability, transferring design defect responsibility from the design-builder to the owner for any systems the ODR's directions affected.
It constitutes constructive acceleration, automatically entitling the design-builder to additional compensation for expedited re-inspection.
It voids the design-builder's professional liability insurance because direct owner involvement in QC constitutes co-design.

Correct answer: It undermines the single-point-responsibility principle by blurring accountability lines, potentially giving the design-builder a defense against quality deficiency claims and exposing the owner to claims for owner-caused delays.

A foundational principle of design-build execution is single-point-responsibility — the design-builder is accountable for both design and construction quality. When an ODR begins directing QC inspections and issuing corrections directly to subcontractors, it fragments that accountability. DBIA's execution guidance warns that this behavior creates two serious risks: (1) the design-builder gains a legitimate defense against quality claims by arguing the owner assumed QC authority, and (2) owner interference in the design-builder's means and methods creates exposure to delay and disruption claims. The Spearin Doctrine applies specifically to design specifications provided by owners, not to QC process interference, making option A a misapplication.

Question 45: Immediately following contract award for a design-build project, what is the primary purpose of the project kick-off meeting?

To finalize the selection of major subcontractors and suppliers.
To mobilize construction equipment and personnel to the site.
To obtain the final notice to proceed from the owner.
To align the entire integrated team on project goals, communication protocols, and team culture. (Correct answer)

Correct answer: To align the entire integrated team on project goals, communication protocols, and team culture.

The post-award kick-off meeting is a critical step in executing a design-build project. Its main goal is to transition from procurement to execution by integrating all key stakeholders (owner, designer, builder) into a cohesive team, establishing clear communication lines, and ensuring everyone is aligned on the project's objectives and the collaborative culture required for success.

Question 46: In the federal sector, a design-build solicitation for a Department of Defense facility requires compliance with UFGS (Unified Facilities Guide Specifications) and UFC (Unified Facilities Criteria). A design-builder proposes an alternate technical concept that meets performance objectives but deviates from a prescriptive UFC standard. What is the correct process for handling this?

The contracting officer may approve the deviation verbally during the proposal clarification phase
The design-builder may proceed without approval since performance-based contracting supersedes prescriptive standards
The deviation is automatically disqualified because federal design-build contracts require strict adherence to all UFC prescriptive requirements
The design-builder must submit a deviation or waiver request to the appropriate authority having jurisdiction prior to contract award or as stipulated in the RFP (Correct answer)

Correct answer: The design-builder must submit a deviation or waiver request to the appropriate authority having jurisdiction prior to contract award or as stipulated in the RFP

UFC and UFGS standards in federal design-build are mandatory unless formally waived. A design-builder proposing a deviation must submit a formal deviation/waiver request through the authority having jurisdiction (AHJ). This process ensures technical review and documented approval — verbal approvals or assumptions of blanket performance-based waivers are not permissible under federal acquisition regulations.

Question 47: How does Progressive Design-Build address the challenge of scope creep during design development?

By prohibiting any changes to the project program after the design-build team is selected
Through ongoing cost transparency and owner-team dialogue that flags scope additions and their cost impact in real time (Correct answer)
By transferring all scope change risk to the design-build team at contract signing
Scope creep is not a relevant concern in Progressive Design-Build

Correct answer: Through ongoing cost transparency and owner-team dialogue that flags scope additions and their cost impact in real time

PDB's open-book, collaborative structure surfaces scope additions and their cost impact immediately, allowing the owner to make informed decisions during design.

Question 48: Under the DBIA framework, which scenario BEST illustrates appropriate use of 'progressive design-build' (PDB) as opposed to traditional lump-sum design-build, specifically within the water sector?

A utility seeking the lowest possible construction cost for a well-understood tertiary treatment upgrade with established performance benchmarks
A regional authority procuring a facility where treatment technology selection, capacity optimization, and regulatory permit conditions are still evolving and require collaborative owner-design-builder development before a fixed price can be established (Correct answer)
A municipality replacing a standard pump station where design requirements, site conditions, and hydraulic parameters are fully defined in the owner's preliminary engineering report
An owner who wants to maintain full design control through 100% construction documents before engaging a contractor

Correct answer: A regional authority procuring a facility where treatment technology selection, capacity optimization, and regulatory permit conditions are still evolving and require collaborative owner-design-builder development before a fixed price can be established

Progressive design-build is specifically suited to projects with high complexity, evolving scope, or regulatory uncertainty — common in advanced water treatment facilities where technology selection, permit conditions, and capacity factors are not resolved at procurement. PDB allows the owner and design-builder to collaborate through scoping and preliminary design before agreeing on a GMP or fixed price, reducing both owner and design-builder risk compared to pricing an incomplete scope. A simple, well-defined pump station is better suited to traditional lump-sum design-build.

Question 49: During closeout of a design-build project, the owner discovers latent defects in the structural system that were not detectable during substantial completion inspection. The design-build contract contains a one-year correction period after substantial completion, and the applicable statute of repose is ten years. The design-builder argues the one-year correction period is the exclusive remedy. Which of the following BEST describes the legal and contractual risk exposure of the design-builder?

The statute of repose only applies to separate design professionals; design-builders operating under a single entity contract are exempt from repose periods entirely.
The one-year correction period defines the warranty obligation for timely correction, but latent defect claims sounding in negligence or implied warranty may survive until the statute of repose expires, exposing the design-builder to longer-tail liability. (Correct answer)
The design-builder's liability for latent defects is capped at the contract value because design-build entities cannot be held to a higher standard than the contract price under any theory of recovery.
The one-year correction period is the design-builder's total liability exposure; once it expires, no claims for latent defects can be pursued regardless of the statute of repose.

Correct answer: The one-year correction period defines the warranty obligation for timely correction, but latent defect claims sounding in negligence or implied warranty may survive until the statute of repose expires, exposing the design-builder to longer-tail liability.

A contractual correction period (often called a 'warranty period') establishes when the owner can demand the contractor return to fix defects — it is not a complete limitations period. Courts have consistently held that latent defects not discoverable during the correction period may still be actionable under negligence, breach of implied warranty, or statutory theories until the applicable statute of repose runs. Design-builders must understand this longer-tail exposure and ensure their professional liability and completed-operations insurance coverage extends accordingly — a one-year correction clause does not extinguish all legal exposure for design deficiencies.

Question 50: A key risk management benefit of the single contract in design-build is the elimination of disputes between the designer and the contractor. How does this benefit the owner?

It guarantees that the project will have no change orders.
It prevents the owner from being responsible for adjudicating conflicts over design errors or constructability issues. (Correct answer)
It allows the owner to dictate the means and methods of construction directly to subcontractors.
It transfers all financial risks, including project funding and interest rate fluctuations, to the design-builder.

Correct answer: It prevents the owner from being responsible for adjudicating conflicts over design errors or constructability issues.

In the traditional Design-Bid-Build method, if a constructability issue arises, the contractor may blame the designer, and the designer may blame the contractor, leaving the owner caught in the middle to resolve the dispute and bear the cost and schedule impacts. In design-build, the design-builder is a single entity responsible for both design and construction, so these internal conflicts are resolved within the design-build team, shielding the owner from such disputes.

Question 51: An owner conducting a two-phase design-build procurement offers a stipend to each unsuccessful Phase 2 proposer. The RFP is silent on intellectual property rights. After award, the owner directs the awarded design-builder to incorporate a distinctive facade concept submitted by one of the unsuccessful proposers. Which statement MOST accurately reflects the legal and ethical risk?

The design-builder who receives the award assumes all IP liability for concepts incorporated at the owner's direction, shielding the owner from any claim.
Without explicit IP assignment or license language in the RFP, the unsuccessful proposer likely retains copyright in the design concept, and the owner's use could constitute infringement even after stipend payment. (Correct answer)
Payment of a stipend automatically conveys a perpetual, unrestricted license to all concepts in the unsuccessful proposals, so the owner faces no risk.
The owner may use any concept from unsuccessful proposals freely because competitive procurement submissions are treated as public domain offers.

Correct answer: Without explicit IP assignment or license language in the RFP, the unsuccessful proposer likely retains copyright in the design concept, and the owner's use could constitute infringement even after stipend payment.

A stipend compensates for the cost of preparing a proposal and may purchase a limited license, but the scope of that license must be explicitly defined. Without RFP language specifying IP assignment or a broad license, copyright in creative design concepts remains with the originating firm. DBIA model procurement documents specifically recommend that owners include clear IP provisions in the RFP to avoid this exact ambiguity.

Question 52: Which of the following best describes the contractual structure of a Progressive Design-Build project?

A single contract between the owner and design-builder, often executed in two distinct phases or with two separate, consecutive agreements. (Correct answer)
Separate contracts between the owner, architect, and contractor managed by a construction manager.
A series of lump-sum contracts awarded to the lowest bidder for each phase of construction.
A multi-party integrated project delivery (IPD) agreement signed by all stakeholders.

Correct answer: A single contract between the owner and design-builder, often executed in two distinct phases or with two separate, consecutive agreements.

Like all design-build methods, PDB utilizes a single point of responsibility. The owner holds one contract with the design-build entity. This contract, however, is structured to accommodate the two-phase process. It can be a single agreement covering both phases (with an authorization to proceed to Phase 2) or two separate, sequential contracts for Phase 1 (pre-construction) and Phase 2 (final design and construction).

Question 53: In the context of Progressive Design-Build, what does 'design assist' from trade contractors primarily mean?

Specialty subcontractors contribute technical expertise during design to improve constructability and cost certainty (Correct answer)
Design assist refers to owner-supplied design standards that the team must follow
Trade contractors review completed designs only after construction documents are 100% finished
Trade contractors take over all design responsibilities from the architect

Correct answer: Specialty subcontractors contribute technical expertise during design to improve constructability and cost certainty

Design assist involves specialty subcontractors providing input during design to enhance constructability, reduce waste, and improve cost reliability.

Question 54: Under the Federal Acquisition Regulation (FAR) Part 36, which specific provision most directly enables federal agencies to use design-build delivery by allowing a two-phase selection process?

FAR 36.300 – Procedures for Architect-Engineer Contracts
FAR 15.101 – Best Value Continuum
FAR 9.104 – Standards for Responsibility
FAR 36.102 – Use of Two-Phase Design-Build Selection Procedures (Correct answer)

Correct answer: FAR 36.102 – Use of Two-Phase Design-Build Selection Procedures

FAR 36.102 specifically authorizes the two-phase design-build selection procedure for federal construction projects, enabling agencies to first shortlist qualified offerors (Phase 1) before requesting detailed technical proposals and price (Phase 2). This provision is the direct statutory mechanism enabling federal design-build procurement.

Question 55: In a design-build GMP contract, cost savings below the GMP are typically handled by:

Retained entirely by the design-builder as additional profit
Shared savings between the owner and design-builder per a negotiated formula (Correct answer)
Applied automatically to fund future change orders
Returned entirely to the owner as a credit

Correct answer: Shared savings between the owner and design-builder per a negotiated formula

GMP contracts commonly include a shared savings clause that incentivizes the design-builder to control costs by splitting underruns with the owner.

Question 56: An owner is using a two-phase best value selection process for a complex hospital project. According to DBIA best practices, what should be the primary focus during Phase 1 (RFQ)?

The qualifications, experience, and past performance of the design-build teams. (Correct answer)
Subcontractor selection and procurement plan.
A firm, fixed price for the entire project.
Detailed design concepts and technical solutions.

Correct answer: The qualifications, experience, and past performance of the design-build teams.

DBIA best practices emphasize that Phase 1 of a two-phase best value procurement should focus on selecting the most qualified teams. The evaluation should be based on factors like experience, past performance, key personnel, and the team's understanding of the project, rather than on detailed design or price at this early stage.

Question 57: A DBIA-procured water treatment plant is being delivered under a progressive design-build contract. After GMP establishment at 60% design, the owner's program manager discovers that the design-builder's cost model omitted $2.1M in process piping because the P&IDs were owner-furnished and contained errors. Under DBIA's risk allocation framework, which party most likely bears this cost and why?

The design-builder, because accepting a GMP transfers all design development risk to the design-builder regardless of the source of the error
The owner and design-builder share the cost equally under a shared-savings/shared-risk provision that applies automatically at GMP
The owner, because owner-furnished design documents (P&IDs) constitute Owner Design Criteria; errors in owner-provided information are an owner risk under DBIA's model agreement (Correct answer)
The design-builder's process engineering subcontractor, because the omission occurred in their scope of responsibility and the design-builder cannot pass process risk upstream

Correct answer: The owner, because owner-furnished design documents (P&IDs) constitute Owner Design Criteria; errors in owner-provided information are an owner risk under DBIA's model agreement

DBIA's model agreement explicitly treats Owner Design Criteria — including owner-furnished drawings, specifications, and technical documents — as owner-provided information. Errors or omissions in that information are an owner risk, entitling the design-builder to a change order. A GMP transfers risk over design development choices within the design-builder's scope, not risk arising from defective owner-furnished information. The shared-risk provision does not automatically apply to owner-caused errors, and the subcontractor's liability flows from the design-builder's contract with them — it does not override the owner/design-builder risk allocation.

Question 58: A design-build RFP that specifies performance criteria rather than prescriptive specifications primarily benefits the owner by:

Allowing design-builders to innovate and propose solutions that best meet project goals (Correct answer)
Reducing the number of responding firms and simplifying evaluation
Shifting all design liability to the owner's retained engineer
Ensuring all proposers submit identical technical approaches for easy comparison

Correct answer: Allowing design-builders to innovate and propose solutions that best meet project goals

Performance-based criteria encourage innovation by allowing design-builders to propose optimal solutions rather than prescribing a single design approach.

Question 59: In a Design-Build project, how is risk for design errors and omissions typically allocated?

Solely to the owner, who provides the initial project criteria.
Shared equally between the owner and the design-build entity through a contingency fund.
To the single-point-of-responsibility design-build entity. (Correct answer)
Solely to the architect/engineer of record.

Correct answer: To the single-point-of-responsibility design-build entity.

A key advantage of the Design-Build delivery method is the single point of responsibility. The design-build entity holds the contract with the owner and is responsible for both design and construction. This means the design-builder assumes the risk for design errors and omissions, eliminating the potential for disputes between a separate designer and builder.

Question 60: During a design-build project, the owner's representative discovers that the structural engineer (a key design-build team member) has a pre-existing professional relationship with a subcontractor being evaluated for the steel package. The design-builder's project manager is aware but has not disclosed this. Under DBIA best practices, what is the MOST appropriate immediate action?

Disqualify the steel subcontractor automatically to eliminate any appearance of impropriety
Allow the structural engineer to continue participating since the relationship was pre-existing and not formed during the project
Remove the structural engineer from all subcontractor evaluation activities and document the conflict in the project record (Correct answer)
Require the owner to waive the conflict in writing before any subcontractor evaluations proceed

Correct answer: Remove the structural engineer from all subcontractor evaluation activities and document the conflict in the project record

DBIA principles require proactive conflict-of-interest management. The correct response is to recuse the conflicted team member from the specific evaluation activity and create a transparent project record. Simply obtaining an owner waiver or automatically disqualifying the subcontractor are disproportionate responses, and allowing the engineer to continue undermines the team's integrity and the owner's trust.

Question 61: In the industrial sector, design-build is often preferred for greenfield manufacturing facilities because it:

Avoids OSHA compliance requirements
Guarantees the lowest possible construction cost
Compresses the schedule from land acquisition to production start (Correct answer)
Eliminates the need for process engineers

Correct answer: Compresses the schedule from land acquisition to production start

Overlapping design and construction phases on greenfield industrial sites can significantly reduce time from land acquisition to first production.

Question 62: What distinguishes a 'design criteria' specification from a 'prescriptive' specification in design-build procurement?

Design criteria specify exact materials and methods; prescriptive define performance outcomes
Design criteria define performance outcomes and functional requirements; prescriptive specify exact materials and methods (Correct answer)
Design criteria are used only for mechanical systems; prescriptive for structural systems
There is no meaningful distinction in design-build contracting

Correct answer: Design criteria define performance outcomes and functional requirements; prescriptive specify exact materials and methods

Design criteria (performance) specifications state what the system must achieve, giving the design-builder flexibility, while prescriptive specifications dictate exactly how to build it.

Question 63: Under DBIA's progressive design-build (PDB) model, an owner retains design review rights through bridging documents and approves a structural system during Phase 1. In Phase 2, after the GMP is established, the approved structural system is found to be non-compliant with a newly enacted seismic code update that took effect between Phase 1 approval and Phase 2 execution. Who bears the cost risk under standard DBIA PDB risk allocation, and why?

The owner bears the risk for the code change itself as a changed condition post-GMP, but the design-builder bears risk for any inherent non-compliance that would have existed under the prior code (Correct answer)
Because the owner approved the structural system, the doctrine of owner acceptance transfers all future compliance risk to the owner permanently
Risk is shared 50/50 by default under DBIA PDB guidelines whenever a code change occurs between Phase 1 and Phase 2
The design-builder bears full risk because design compliance is always the design-builder's professional responsibility, regardless of owner approval or code change timing

Correct answer: The owner bears the risk for the code change itself as a changed condition post-GMP, but the design-builder bears risk for any inherent non-compliance that would have existed under the prior code

DBIA PDB risk allocation recognizes that owner approval of a design element does not transfer the design-builder's professional responsibility for code compliance — but it does not insulate the design-builder from the cost of a post-GMP regulatory change, which constitutes a change in law or a changed condition. The correct split: the design-builder bears risk for compliance with the code in effect when the design was developed (if there was latent non-compliance with the old code, that's design-builder liability); however, the incremental cost of conforming to a new code enacted after GMP establishment is an owner risk as a change in law. Neither full transfer to the owner via approval doctrine nor a blanket 50/50 split reflects DBIA principles.

Question 64: Which contract standard is most commonly referenced for Progressive Design-Build projects in the United States?

DBIA Document No. 540 Progressive Design-Build Contract (Correct answer)
FAR Part 36 Government Construction Contracts
AIA A101 Stipulated Sum Agreement
ConsensusDocs 410 Standard Design-Build Agreement (Lump Sum)

Correct answer: DBIA Document No. 540 Progressive Design-Build Contract

DBIA Document No. 540 is the standard contract document specifically developed for Progressive Design-Build projects in the US.

Question 65: A waiver of subrogation clause in a design-build contract has what effect?

It lets the insurer sue any project party after paying a loss
It cancels the performance bond
It doubles the policy limits
It stops insurers from recovering paid losses from other parties to the contract, reducing litigation among project participants (Correct answer)

Correct answer: It stops insurers from recovering paid losses from other parties to the contract, reducing litigation among project participants

Waivers of subrogation stop an insurer from stepping into its insured's shoes to sue other project parties for covered losses.

Question 66: In DBIA standard documents, which party typically has initial authority to resolve disputes before formal ADR proceedings begin?

The lead designer on the project
The Owner's Representative and the Design-Build Entity's Project Manager through direct negotiation (Correct answer)
A government oversight agency
A third-party arbitrator

Correct answer: The Owner's Representative and the Design-Build Entity's Project Manager through direct negotiation

DBIA documents establish that the Owner's Representative and the D-B entity's project manager should first attempt direct negotiation to resolve disputes informally before escalating.

Question 67: Which quality management approach is MOST consistent with DBIA best practices during design-build construction?

Delegating all quality responsibilities to individual subcontractors without oversight
Conducting a single quality review at project completion before owner acceptance
Implementing a formal Quality Management Plan with in-process inspections, documentation, and hold points (Correct answer)
Relying exclusively on the local building inspector to catch quality deficiencies

Correct answer: Implementing a formal Quality Management Plan with in-process inspections, documentation, and hold points

DBIA best practices call for a proactive Quality Management Plan with defined inspection hold points and documentation throughout construction, not reactive end-of-project reviews.

Question 68: A design-build team is evaluating a lump-sum, bridging-document RFP for a wastewater treatment facility. The bridging documents include 30% design drawings prepared by the owner's engineer. The RFP states the design-builder assumes 'full design responsibility upon contract execution.' Three months into detailed design, the design-builder discovers the bridging documents contain a fundamental process design error that requires significant rework. Which analysis most accurately reflects the risk allocation under DBIA principles?

Risk is automatically allocated to whichever party's insurance covers the loss, as DBIA contracts defer to insurance outcomes on design errors
The owner bears responsibility for errors in the bridging documents they provided, but the design-builder bears responsibility for failing to identify the error during the proposal phase if it was discoverable through reasonable professional review (Correct answer)
The owner bears full responsibility because bridging documents always remain the owner's design under DBIA contract structure
The design-builder bears full responsibility because the 'full design responsibility' clause is unambiguous and all-encompassing

Correct answer: The owner bears responsibility for errors in the bridging documents they provided, but the design-builder bears responsibility for failing to identify the error during the proposal phase if it was discoverable through reasonable professional review

Bridging-document risk allocation is nuanced under DBIA principles. The owner generally retains responsibility for errors embedded in their bridging documents — these represent owner-directed design. However, the design-builder, as the professional design entity taking over the design, has a duty to conduct reasonable professional review of furnished documents. If the error was patent (readily discoverable by a competent professional), the design-builder's failure to identify and flag it during proposal or early design may transfer some or all of the risk. If the error was latent and not discoverable through reasonable review, the owner's liability for the bridging document error is more clearly preserved despite 'full design responsibility' language.

Question 69: In design-build contracts, what does 'open-book accounting' refer to?

Full transparency of project costs shared with the owner (Correct answer)
Publishing project costs online for public review
A requirement to disclose all subcontractor mark-ups publicly
An audit of the design-builder's overhead rates

Correct answer: Full transparency of project costs shared with the owner

Open-book accounting allows the owner to review actual costs, fostering trust and collaboration in cost-reimbursable design-build contracts.

Question 70: What is the primary purpose of an industry review (or 'industry forum') conducted before issuing an RFP?

To allow owners to gather market feedback and refine procurement documents before release (Correct answer)
To score shortlisted firms on technical capacity
To negotiate contract terms with the preferred proposer
To officially pre-qualify design-build teams

Correct answer: To allow owners to gather market feedback and refine procurement documents before release

Industry forums allow owners to present draft procurement documents to potential proposers, gather feedback, and improve document quality before formal release.

Question 71: A DBIA Fellow is retained as an expert witness for a design-build dispute. During deposition preparation, retaining counsel instructs the Fellow to omit from testimony a specific industry standard that contradicts the counsel's legal theory — a standard the Fellow knows is directly relevant and widely applied. Under the DBIA Code of Professional Conduct, the Fellow should:

Refuse to omit the standard, since expert witnesses must provide complete and objective opinions regardless of which party retained them, and the Code prohibits deceptive professional conduct (Correct answer)
Omit the standard during deposition but volunteer it on cross-examination, satisfying both the legal strategy and eventual full disclosure
Withdraw from the engagement without explanation to avoid violating either counsel's instructions or the Code's honesty requirements
Follow counsel's instruction, as the attorney-client work product doctrine governs expert witness preparation and supersedes the DBIA Code in litigation contexts

Correct answer: Refuse to omit the standard, since expert witnesses must provide complete and objective opinions regardless of which party retained them, and the Code prohibits deceptive professional conduct

DBIA credentialed professionals acting as expert witnesses retain their ethical obligations under the Code, including the duty to provide truthful, complete, and non-deceptive professional opinions. The expert's primary obligation is to the court and to honest professional practice, not to the retaining party's legal strategy. Selectively omitting a directly relevant and widely applied standard constitutes a form of deceptive conduct prohibited by the Code. The proper response is to refuse the instruction — and if necessary, withdraw if counsel insists.

Question 72: What does 'schedule float' (also called slack) represent in a project schedule?

Time allocated for owner reviews between design milestones
The gap between the contract completion date and the substantial completion date
Extra budget reserved for schedule acceleration costs
The amount of time an activity can be delayed without delaying the project completion date (Correct answer)

Correct answer: The amount of time an activity can be delayed without delaying the project completion date

Float represents scheduling flexibility; activities with float can absorb delays without impacting the critical path or final completion date.

Question 73: A DBIA member serving as design-build project executive learns that a colleague at the same firm — also DBIA-credentialed — has submitted a change order with cost data the executive knows is materially inflated. The project is for a private owner with whom the firm has a strong long-term relationship. Under the DBIA Code, what obligation does the project executive have?

No obligation to act, as internal firm billing disputes are outside the scope of the Code and the owner has independent rights to audit change orders
An obligation to report the colleague to DBIA's ethics board before raising the issue internally, to ensure an independent record exists
An obligation to address the inflated cost data internally and, if the firm fails to correct it, to consider whether further action — including disclosure to the owner — is required to avoid personal complicity in deceptive conduct (Correct answer)
An obligation to notify the owner immediately and simultaneously, without first attempting internal resolution, since delay constitutes concealment

Correct answer: An obligation to address the inflated cost data internally and, if the firm fails to correct it, to consider whether further action — including disclosure to the owner — is required to avoid personal complicity in deceptive conduct

The DBIA Code prohibits participating in or facilitating deceptive professional conduct. When a member has actual knowledge of a colleague's material misrepresentation in a change order, silence makes them complicit. The appropriate sequence is to address it internally first — giving the firm the opportunity to correct the error — but if the firm refuses or the inflated data is submitted to the owner, the member must take further steps to avoid personal culpability for ongoing deception. The Code does not require bypassing internal channels, but also does not permit indefinite silence.

Question 74: What does 'single point of responsibility' mean in the context of design-build team integration?

The lead designer assumes financial risk for cost overruns
The owner manages all subcontractor relationships directly
The design-builder holds contractual accountability for both design and construction (Correct answer)
Only one team member makes all project decisions

Correct answer: The design-builder holds contractual accountability for both design and construction

Single point of responsibility means the design-build entity is contractually accountable to the owner for the complete project outcome, eliminating owner-managed coordination gaps.

Question 75: Which of the following is NOT a typical benefit attributed to design-build delivery?

Faster project delivery through schedule compression
Single point of accountability for design and construction quality
Greater owner control over detailed design decisions throughout the project (Correct answer)
Lower total project cost through reduced change orders

Correct answer: Greater owner control over detailed design decisions throughout the project

Design-build typically reduces owner control over detailed design decisions, as that authority is delegated to the design-builder within defined parameters.

Question 76: A design-build team's integrated design process for a high-performance campus building calls for an energy charrette. At which point does DBIA-aligned integrated project delivery guidance say the charrette delivers the greatest influence on life-cycle outcomes at the lowest cost of change?

Only after the GMP or lump sum is established, to avoid disturbing pricing
During commissioning, once actual performance data is available
After construction documents are 90% complete so that all details are known
During the earliest conceptual/programming phase, before building form, orientation, and major systems are fixed (Correct answer)

Correct answer: During the earliest conceptual/programming phase, before building form, orientation, and major systems are fixed

The ability to influence cost and performance is highest, and the cost of change lowest, in early conceptual design (the MacLeamy curve). Decisions on orientation, massing, glazing ratio, and system type made early drive most of the energy and carbon outcomes, which is why design-build teams bring in constructors and engineers at the start.

Question 77: Which of the following represents a significant misallocation of risk that contradicts the principles of 'Design-Build Done Right®'?

The contract allocating the risk of obtaining standard building permits to the design-builder.
The contract requiring the design-builder to assume liability for all unforeseen site conditions without providing any preliminary site information. (Correct answer)
The owner retaining the risk for hazardous material abatement if discovered on site.
The design-builder accepting schedule risk associated with coordinating its design and construction activities.

Correct answer: The contract requiring the design-builder to assume liability for all unforeseen site conditions without providing any preliminary site information.

Forcing a design-builder to accept a 100% 'blind' risk for something like unforeseen site conditions is a poor practice. DBIA principles state that risk should be allocated to the party best able to manage it. Without any information, the design-builder cannot reasonably assess or price this risk, forcing them to either carry an excessive contingency (raising the project cost) or potentially face a catastrophic loss. The owner is better positioned to manage this risk initially by providing all known information.

Question 78: What is the primary goal of value engineering (VE) in a design-build project?

Select cheaper materials regardless of long-term performance
Accelerate the construction schedule at any cost
Achieve required functions at the lowest overall life-cycle cost (Correct answer)
Reduce design fees by eliminating design team members

Correct answer: Achieve required functions at the lowest overall life-cycle cost

VE systematically analyzes functions to identify alternatives that deliver the required performance at reduced total cost over the project's life cycle.

Question 79: During construction under a design-build contract, a long-span roof truss fails because of a design error, damaging installed mechanical equipment below. The builder's risk policy has a standard faulty-design exclusion with an ensuing-loss (resulting-damage) carve-back. How is the loss most likely to be handled?

The cost to redesign and replace the defective truss is excluded, but the resulting damage to the mechanical equipment may be covered (Correct answer)
Only the redesign cost is covered, and the equipment damage goes to the design-builder's CGL policy
Everything is covered, including redesigning and replacing the truss, because builder's risk is all-risk coverage
Everything is excluded, because any loss linked to faulty design is excluded

Correct answer: The cost to redesign and replace the defective truss is excluded, but the resulting damage to the mechanical equipment may be covered

Builder's risk policies usually exclude the cost of correcting faulty design, workmanship, or materials themselves. The ensuing-loss carve-back, however, restores coverage for separate physical damage that results from the defect, such as the damaged mechanical equipment. Which form is used (for example, the LEG 1/2/3 defects exclusion forms) changes how much of the defective part is covered, but the basic split holds: the defective work is excluded and the resulting damage is covered. The cost to fix the design itself is generally left for professional liability insurance.

Question 80: The DBIA Waterfall concept in design-build legislation refers to which principle?

Sequential phases of design approval before construction begins
Federal model legislation that states adapt for their own enabling statutes (Correct answer)
Cascading responsibility from owner to design-builder for all project elements
Progressive payment schedule tied to design milestones

Correct answer: Federal model legislation that states adapt for their own enabling statutes

DBIA's model legislation approach provides a template that states can adapt, creating a cascading effect of similar enabling statutes across jurisdictions.

Question 81: How does the selection process in Progressive Design-Build (PDB) primarily differ from a traditional fixed-price (lump sum) Design-Build procurement?

PDB selection is based primarily on the design-builder's qualifications, experience, and team culture. (Correct answer)
Traditional Design-Build selection ignores qualifications and focuses only on price.
In PDB, the owner provides a 100% complete design before selecting the builder.
PDB selection is based solely on the lowest responsive bid price.

Correct answer: PDB selection is based primarily on the design-builder's qualifications, experience, and team culture.

A fundamental characteristic of PDB is that the design-build team is selected primarily, and sometimes exclusively, on qualifications and approach, not on a final price. In contrast, traditional lump sum design-build procurements typically require proposers to submit a firm price along with their technical proposal, making price a significant, and often decisive, evaluation factor at the time of selection.

Question 82: Under DBIA best practices, which document type is typically released first in a two-phase design-build procurement?

Request for Qualifications (RFQ) (Correct answer)
Invitation for Bid (IFB)
Notice to Proceed (NTP)
Request for Proposals (RFP)

Correct answer: Request for Qualifications (RFQ)

In two-phase procurement, an RFQ is issued first to establish a shortlist of qualified teams before the full RFP is released to those firms.

Question 83: An aviation authority is procuring a terminal expansion using a two-phase design-build selection. The RFP includes a stipend for unsuccessful shortlisted proposers. A proposer withdraws after Phase 1 shortlisting but before submitting a Phase 2 proposal. Under standard DBIA guidance, what is the typical stipend eligibility outcome?

Stipend eligibility for a withdrawing proposer depends on the specific RFP terms, which may require a Phase 2 submission or grant of IP rights to receive payment (Correct answer)
The stipend is forfeited entirely because the proposer did not submit a compliant Phase 2 proposal
The owner is legally required to pay the stipend regardless of withdrawal under aviation procurement regulations
The withdrawing proposer receives the full stipend because they incurred costs during the Phase 1 process

Correct answer: Stipend eligibility for a withdrawing proposer depends on the specific RFP terms, which may require a Phase 2 submission or grant of IP rights to receive payment

Stipends in design-build are governed by the specific terms of the RFP, not a universal rule. Most RFPs condition stipend payment on submission of a responsive Phase 2 proposal and grant of intellectual property rights to the owner. A proposer who withdraws after shortlisting typically does not meet those conditions unless the RFP explicitly provides a partial or unconditional stipend. DBIA recommends owners clearly define stipend eligibility criteria to avoid disputes.

Question 84: What is the primary purpose of 'substantial completion' in a design-build contract?

The moment the design-builder receives final payment from the owner
The date the certificate of occupancy is issued by the local jurisdiction
The point at which the owner can beneficially occupy and use the facility for its intended purpose (Correct answer)
The date when all punch list items have been fully resolved and closed

Correct answer: The point at which the owner can beneficially occupy and use the facility for its intended purpose

Substantial completion marks when the facility is sufficiently complete for the owner to use it, triggering warranty periods, final retainage release processes, and other contract milestones.

Question 85: How should design-build contracts address warranty obligations?

The owner waives all warranty rights
Warranties expire at substantial completion
Design-build projects do not have warranties
Contracts should distinguish between construction warranties (typically 1-year correction period) and the designer's ongoing professional standard of care obligation (Correct answer)

Correct answer: Contracts should distinguish between construction warranties (typically 1-year correction period) and the designer's ongoing professional standard of care obligation

Design-build warranty structures must address both the construction correction period and the professional standard of care for design services.

Question 86: Which of the following best describes 'scope creep' risk in design-build contracts and how it is typically addressed?

Scope creep is eliminated because design-builders control all design decisions
Scope creep is the owner's sole responsibility under all contract types
Scope creep only affects cost-plus contracts, not lump sum
Scope creep is managed through a clear owner's criteria baseline and formal change order process for deviations (Correct answer)

Correct answer: Scope creep is managed through a clear owner's criteria baseline and formal change order process for deviations

Well-defined owner's criteria establish the original scope baseline, and a disciplined change order process captures and prices any deviations from that baseline.

Question 87: Why are payment bonds especially important on public design-build projects?

Public owners' property generally cannot be subject to mechanic's liens (Correct answer)
They cover the owner's design changes
Payment bonds replace the need for builder's risk coverage
They guarantee the designer's standard of care

Correct answer: Public owners' property generally cannot be subject to mechanic's liens

Mechanic's liens usually cannot attach to public property, so the payment bond is the substitute protection for unpaid subs and suppliers.

Question 88: What is a 'bridging' approach, and how does it relate to Progressive Design-Build?

Bridging is the same as Progressive Design-Build and uses identical contracts
Bridging is a method where the owner develops partial design documents before engaging a design-build team, which differs from PDB's approach (Correct answer)
Bridging is another term for the GMP negotiation phase in PDB
Bridging refers to the physical connection between project phases in PDB schedules

Correct answer: Bridging is a method where the owner develops partial design documents before engaging a design-build team, which differs from PDB's approach

Bridging involves owner-developed design criteria documents used to solicit design-build proposals, which contrasts with PDB's approach of selecting the team first and developing design collaboratively.

Question 89: What is a key advantage of Progressive Design-Build for owners dealing with tight or uncertain market conditions?

It eliminates the need for contingency budgets entirely
It locks in subcontractor pricing at the earliest possible stage, regardless of market
It allows cost to be established once market conditions and design are sufficiently clear, reducing contingency (Correct answer)
It forces all market risk onto the design-build team at contract inception

Correct answer: It allows cost to be established once market conditions and design are sufficiently clear, reducing contingency

By delaying price commitment until design and market conditions are better understood, PDB reduces the contingency premium that would otherwise be added for uncertainty.

Question 90: A design-build team on a fast-track project is experiencing delays due to misaligned expectations between the design and construction personnel. Decisions made by designers are frequently challenged by the construction team for constructability and cost. According to DBIA principles, which of the following actions would be the most effective first step to improve team integration?

Procure a third-party mediator to resolve conflicts as they arise.
Require the constructor to submit all constructability concerns in a formal RFI process.
Implement a co-location strategy where key team members work together in a shared physical or virtual space. (Correct answer)
Escalate all disputes to the owner for a final binding decision.

Correct answer: Implement a co-location strategy where key team members work together in a shared physical or virtual space.

Co-location is a core DBIA practice for fostering real-time collaboration, breaking down silos, and allowing for immediate feedback on design, cost, and constructability. It promotes the 'one-team' culture. Formal processes like RFIs and escalation to the owner re-introduce the adversarial and siloed communication that design-build aims to eliminate. A mediator is a reactive, not a proactive, solution to a systemic communication problem.

Question 91: How does risk allocation in Progressive Design-Build compare to a traditional lump-sum design-bid-build project?

PDB eliminates all financial risk for the owner by guaranteeing cost certainty at contract signing
Risk allocation in PDB and design-bid-build is identical
PDB places all financial risk on the design-build team from day one
PDB shares risk more collaboratively between owner and team during design, with risk transferring at GMP (Correct answer)

Correct answer: PDB shares risk more collaboratively between owner and team during design, with risk transferring at GMP

PDB distributes risk during early design phases collaboratively, with clearer risk transfer occurring when the GMP is established.

Question 92: Which statement best describes why DBIA-aligned project teams typically use an integrated design process (charrette) at the earliest stage of a high-performance design-build project?

Because LEED requires a charrette to be held with the USGBC present before any award
Because passive strategies such as orientation, massing, and envelope-to-glazing ratios have the greatest influence on energy performance and are least expensive to change before design is advanced (Correct answer)
Because the design-builder can then assign all sustainability risk to the subcontractors
Because charrettes replace the need for energy modeling and commissioning

Correct answer: Because passive strategies such as orientation, massing, and envelope-to-glazing ratios have the greatest influence on energy performance and are least expensive to change before design is advanced

The cost of changing design decisions rises sharply as design advances, while the influence on performance is highest early (the MacLeamy curve concept). An integrated process lets architects, engineers, constructors, and the owner optimize passive strategies before systems are locked in. Charrettes do not replace modeling or commissioning, are not mandated with USGBC attendance, and do not legitimately shift all risk to subcontractors.

Question 93: An owner using a Best Value procurement method assigns 40% weight to price and 60% weight to technical/qualifications factors in its RFP scoring matrix. After proposals are received, the owner's evaluation committee wants to adjust the weighting to 50/50 because technical scores were clustered. Under DBIA procurement principles, this adjustment is:

Permissible if the change is documented in a written addendum issued before evaluation scores are finalized
Not permissible, because evaluation criteria and weightings must be established and disclosed before proposals are submitted and cannot be changed post-submission (Correct answer)
Not permissible only if the procurement is publicly funded; private owners may adjust criteria at any stage
Permissible only if all proposers unanimously consent in writing to the revised weighting

Correct answer: Not permissible, because evaluation criteria and weightings must be established and disclosed before proposals are submitted and cannot be changed post-submission

A foundational principle of fair procurement—reinforced by DBIA standards—is that evaluation criteria and their weightings must be fixed and disclosed to all proposers before proposals are submitted. Changing weightings after receipt of proposals undermines competitive fairness, exposes the owner to legal challenge, and violates the transparency requirements that make Best Value selection defensible. This rule applies regardless of funding source.

Question 94: A key feature of the Progressive Design-Build process is the contractual provision that allows the owner to end the agreement with the design-builder if they cannot mutually agree on the commercial terms for the construction phase. What is this provision commonly called?

A scope validation checkpoint.
An 'off-ramp' option. (Correct answer)
A termination for convenience clause.
A collaborative design review gate.

Correct answer: An 'off-ramp' option.

The 'off-ramp' is a distinct feature of PDB that gives the owner a safety net. If, after Phase 1 (design and pre-construction services), the owner and design-builder cannot agree on the GMP or other commercial terms for Phase 2 (construction), the owner can exercise this option, conclude the agreement, and potentially use the developed design to procure a constructor through other means.

Question 95: Which of the following is a common challenge owners face when implementing Progressive Design-Build for the first time?

Lack of any legal framework or contract templates for PDB
Excessive design-build team control over the final GMP without owner input
Too many fixed-price bids from competing design-build teams
Difficulty engaging the owner's internal team in ongoing collaborative design decisions (Correct answer)

Correct answer: Difficulty engaging the owner's internal team in ongoing collaborative design decisions

First-time PDB owners often struggle to sustain the active internal engagement required during design development, since PDB demands more owner participation than traditional delivery.

Question 96: In federal design-build procurement, the Phase I solicitation (Request for Qualifications) typically evaluates which of the following?

Final GMP proposal with design development documents
Past performance, technical approach, and management qualifications (Correct answer)
Schematic design drawings and outline specifications only
Detailed technical proposals and lump-sum price

Correct answer: Past performance, technical approach, and management qualifications

Phase I evaluates offerors' qualifications including past performance, technical approach, and management capability to shortlist firms for Phase II.

Question 97: Which characteristic makes design-build especially suitable for disaster recovery and emergency infrastructure replacement?

Automatic waiver of environmental review
Compressed schedule through overlapping design and construction (Correct answer)
Lower bonding requirements
Fewer inspections required

Correct answer: Compressed schedule through overlapping design and construction

Overlapping design and construction phases dramatically compress schedules, which is critical when rapid restoration of infrastructure is needed after a disaster.

Question 98: A public agency is preparing a Request for Proposal (RFP) for a design-build project. To encourage high-quality, innovative proposals from the shortlisted firms, the agency is considering offering a payment to the unsuccessful proposers. This payment is known as a:

Stipend (Correct answer)
Performance bonus
Pre-construction service fee
Contingency fee

Correct answer: Stipend

A stipend is a payment offered to unsuccessful, but responsive, proposers in a design-build competition to offset the significant cost of preparing a detailed proposal. This practice encourages more firms to compete, leading to better quality and more innovative solutions for the owner.

Question 99: What is 'construction phase quality assurance' (QA) versus 'quality control' (QC)?

QA is performed by the owner; QC is performed exclusively by the design-builder
QA and QC are interchangeable terms with no meaningful distinction in design-build
QA verifies that QC processes are being properly followed; QC involves the actual inspection and testing activities (Correct answer)
QA covers design deliverables; QC covers construction workmanship only

Correct answer: QA verifies that QC processes are being properly followed; QC involves the actual inspection and testing activities

QA is the oversight function confirming that quality processes are in place and functioning, while QC is the hands-on activity of inspecting, testing, and verifying work.

Question 100: Which federal law, enacted in 1996, most significantly expanded the use of design-build for federal civil works projects by authorizing the Army Corps of Engineers and other agencies to use alternative contracting methods including design-build?

The Water Resources Development Act of 1996 (Correct answer)
The Competition in Contracting Act of 1984
The Clinger-Cohen Act of 1996
The Federal Acquisition Streamlining Act of 1994

Correct answer: The Water Resources Development Act of 1996

The Water Resources Development Act (WRDA) of 1996 specifically authorized the Army Corps of Engineers to use design-build contracting for civil works projects. While Clinger-Cohen addressed IT acquisition reform and FASA streamlined procurement broadly, WRDA 1996 was the targeted legislation that opened design-build for federal civil works, which had historically been tightly constrained to traditional delivery methods.
