What is the purpose of descriptive specifications in construction?

Descriptive specifications play a crucial role in construction by detailing the materials and workmanship required for a project. This means they specify the types of materials that should be used, their quality standards, and the methods by which they should be installed or applied. By providing these in-depth details, descriptive specifications ensure that everyone involved in the project, including contractors and subcontractors, has a clear understanding of the expectations and requirements. This clarity helps maintain quality control and consistency throughout the construction process, ultimately leading to a finished product that meets the design intent and standards set forth by the project stakeholders.

In contrast, outlining performance standards focuses on the outcomes rather than the specifics of materials and methods. General guidance may not provide the necessary detail needed for precise execution, while setting project timelines does not directly relate to the specification of materials and workmanship but rather to the scheduling aspect of construction management.
