DBIA Project Delivery Method Selection 6

Question 1

Under the DBIA's qualifications-based selection guidance, an owner using a two-phase design-build procurement shortlists three teams in Phase 1 but then adds a new evaluation criterion in Phase 2 that was not disclosed in the original RFQ. What is the PRIMARY procurement integrity risk this creates beyond potential legal challenge?

Accepted Answer

It may have deterred better-qualified teams from submitting in Phase 1, permanently distorting the competitive pool

Answer

The most insidious procurement integrity risk of adding undisclosed criteria in Phase 2 is not the legal exposure — it is the permanent distortion of the competitive pool. Teams that would have been highly responsive to the new criterion may have evaluated the RFQ, concluded they were not competitive based on the disclosed criteria, and declined to submit. By the time the new criterion appears in Phase 2, those superior teams are already eliminated from competition and cannot be recovered. This is why DBIA's procurement guidance emphasizes that all material evaluation criteria must be disclosed at the earliest stage, because the composition of the shortlist itself depends on that disclosure.

Question 2

An owner has a highly complex water treatment facility project with significant subsurface uncertainty, a fixed legislative budget cap, and an internal team with limited construction management bandwidth. Which delivery method selection factor should carry the MOST weight in this scenario?

Accepted Answer

The project complexity, favoring progressive design-build to maintain owner control over technical decisions

Answer

When technical complexity is extreme and subsurface conditions are uncertain, progressive design-build allows the owner to maintain iterative control over scope definition before committing to a GMP, avoiding premature risk transfer. A fixed GMP under CM-at-Risk or traditional design-build with unresolved geotechnical conditions often produces inflated contingencies or disputes. The owner's limited bandwidth is a real constraint but should not override the need for technical flexibility on a high-complexity, high-uncertainty project.

Question 3

Under DBIA's risk allocation framework, which scenario represents an INAPPROPRIATE use of design-build as the selected delivery method?

Accepted Answer

A project requiring a highly prescriptive, government-mandated design standard where deviations require legislative approval

Answer

Design-build derives its value from the design-builder's ability to optimize solutions within performance-based criteria. When a project is governed by prescriptive government-mandated design standards that require legislative approval for any deviation, the design-builder's flexibility is eliminated, negating the primary advantages of the method. This scenario effectively forces design-build to operate like design-bid-build but with a single contract, creating accountability confusion without corresponding benefit.

Question 4

An owner selects design-build for a transit station and issues an RFP with highly detailed, prescriptive design specifications developed by a third-party engineer. During construction, the design-builder discovers that following the prescriptive specifications creates a code-compliance conflict. Who bears responsibility for the resulting cost impact under standard DBIA risk allocation principles?

Accepted Answer

The owner, because the prescriptive specifications were owner-furnished information that the design-builder was required to follow

Answer

Under DBIA risk allocation doctrine, when an owner provides prescriptive design specifications (bridging documents) that the design-builder is contractually obligated to follow, the owner retains the design risk embedded in those specifications. If the owner-furnished prescriptive design creates a downstream compliance conflict, the resulting cost impact is an owner risk. This is a critical distinction from performance specifications, where the design-builder has solution flexibility and therefore owns the design risk. The DBIA standard form contracts reinforce this through provisions on owner-furnished information.

Question 5

A public owner comparing delivery methods calculates that design-build would reduce the project schedule by 14 months compared to design-bid-build. However, their legal counsel notes that state procurement law requires a demonstrated 'public benefit' justification specifically for design-build use. Which factor is LEAST relevant to constructing that public benefit justification?

Accepted Answer

The design-builder's in-house workforce retention rates compared to industry average

Answer

Public benefit justifications for design-build procurement must connect to measurable owner or public outcomes: schedule savings translated to monetary value (carrying costs, tax revenue, service delivery), reduced administrative burden, and inflation mitigation are all directly quantifiable and relevant. The design-builder's internal workforce retention rate is an internal business metric of the proposing entity and has no bearing on the public benefit to the owner or taxpayers — it cannot be known at the time of delivery method selection and doesn't translate to a public outcome.
