_____ Specification: Owner only provides the requirement(s) for the end result of an element that will be designed by others.

• A. Performance
• B. Prescriptive
• C. Functional
• D. Narrative

Answer: (A)

Performance specifications describe the end result that must be achieved for an element, while leaving the means of achieving it to the designers or builders. In this scenario, the owner provides only the outcome or performance criteria, not how to design or construct it. That focus on the required result, rather than the exact methods or materials, is what makes it a performance specification. It enables innovative approaches and contractor-led solutions as long as the final performance meets the stated criteria, and it typically shifts more risk to the party responsible for delivering that performance. Prescriptive specifications would spell out exact materials, products, or installation methods, which isn’t what the prompt describes. Narrative or functional specifications describe uses or general functions but don’t necessarily define measurable end performance, so they don’t align as closely with specifying the desired end result.
