Performance requirements define measurable outcomes such as STC or durability.

Performance requirements define measurable outcomes such as STC or durability.

• A. They describe how the product is built
• B. They govern project budget
• C. They focus on exterior aesthetics
• D. They define measurable outcomes like STC and durability

Answer: (D)

Performance requirements specify the results the project must achieve, not the exact way to build it. They set measurable outcomes that can be tested or verified, such as acoustical performance (STC) and durability (long-term performance). This lets the design-build team propose solutions that meet those outcomes while choosing materials and methods that fit the project, encouraging innovation without sacrificing performance. Describing how the product is built would be prescriptive detail, not a performance outcome. Budget is a separate constraint, and exterior aesthetics address appearance rather than measurable performance.
