In the context of project specifications, what is a common trait of a descriptive specification?

A descriptive specification is characterized by its detailed outline of the exact requirements and methods to be used in a project. This type of specification provides comprehensive instructions regarding the materials, workmanship, and construction techniques that must be adhered to. By focusing on these specific details, it ensures that all parties involved have a clear understanding of what is expected, which minimizes ambiguity and helps maintain quality and consistency in the execution of the project.

Unlike other types of specifications, such as performance specifications that focus more on the outcomes and leave room for variations in how those outcomes are achieved, descriptive specifications impose strict guidelines. This approach ensures that the contractor knows precisely what to do, which is essential in construction projects where precision and compliance with specific standards and codes are crucial.

The other options reflect aspects that characterize different types of specifications. For instance, specifications that allow for flexibility or include alternatives for product use focus on broader performance goals or products that meet certain criteria rather than detailing exact methods and requirements.
