Which of the following is an example used to illustrate a Performance requirement in classification systems?

• A. Uniformat C10
• B. STC 35
• C. 1000 worker office space
• D. Office lighting fixture spec

Answer: (A)

Classification systems organize requirements by system or element and provide a coded way to express performance goals within that structure. Uniformat uses codes like C10 to designate a specific building system area, and within that area you can articulate performance requirements tied to that system. This makes the performance requirement clear, traceable, and comparable across projects and procurement approaches. The other options don’t show how a performance goal is embedded in a classification framework: STC 35 is a performance rating, not a coded classification item; a 1000‑worker office space is a size/occupancy descriptor; and an office lighting fixture spec is a product-level detail rather than a classification-coded performance illustration.
