What are the two phases of Progressive DB?

• A. Preliminary Services; Final Design & Construction
• B. Phase 1 and Phase 2
• C. Basis of Design; Design Builder
• D. Schematic Design; Construction Administration

Answer: (A)

Progressive Design-Build is structured in two distinct phases to combine early designer involvement with later construction certainty. The first phase, Preliminary Services, focuses on shaping the project through program refinement, concept development, risk and cost assessment, and establishing a price target that guides decisions. The second phase, Final Design & Construction, delivers the detailed design and then builds the project under the agreed terms, often with a guaranteed maximum price or target cost tied to the early work. This two-phase setup is why the choice naming Preliminary Services and Final Design & Construction is the best match. The other options describe phases or elements from different procurement or design processes, not the Progressive DB framework.
