A specification detailing concrete coverage for reinforcement bars is classified as what type?

A specification detailing concrete coverage for reinforcement bars falls under the category of a performance specification. This type of specification focuses on the required outcomes or performance characteristics that must be achieved rather than the exact materials or methods to be used. By focusing on the desired performance—such as strength, durability, or the specific coverage requirements around the reinforcement bars—this specification allows for flexibility in how contractors achieve those results.

In contrast, a descriptive specification would provide detailed descriptions of materials and methods to be used, specifying exactly how the work should be performed. A proprietary specification would specifically name particular products or manufacturers, limiting options to those specified. A combination specification merges both performance and descriptive elements but is not solely performance-based like this situation. Therefore, identifying this specification as a performance specification is correct, as it emphasizes achieving certain results rather than detailing specific materials or methods.
