What type of specifications describe the materials to be used and the workmanship required to fabricate and install those materials?

Descriptive specifications provide details about the materials to be used, along with the workmanship required to fabricate and install those materials. This type of specification outlines the physical and technical characteristics that the materials must possess, ensuring that the end product meets specific standards of quality and performance.

Descriptive specifications often include detailed descriptions of the materials, processes, and installation techniques, making it clear to contractors and builders exactly what is expected in terms of quality and compliance. By focusing on the specific characteristics of materials and workmanship, these specifications help to minimize ambiguity and ensure that the project outcomes align with the designer’s intent.

In contrast, performance specifications focus more on the outcomes or performance standards that the materials and construction methods must achieve, rather than detailing the exact materials and workmanship. Volumetric specifications deal with the quantities and volumes of materials needed for a project, while standard specifications often refer to established guidelines or norms in the industry without going into the specifics of materials and workmanship.
