What is the term for a specification that provides detailed instructions on how to construct a particular aspect of work?

The term "Design Specification" refers to a comprehensive document that outlines the detailed instructions required to construct a specific aspect of a project. It encompasses various critical elements such as materials, assembly processes, dimensions, and tolerances necessary for achieving the desired outcome in construction or manufacturing. The importance of a Design Specification lies in its ability to offer clarity and guidance to engineers, contractors, and other stakeholders, ensuring that the constructed elements meet the intended design requirements and functionality.

In contrast, a Performance Specification typically focuses on the desired outcomes or performance criteria but does not specify how to achieve those results, while a Technical Specification generally includes a variety of technical details without being solely focused on construction methods. Project Specifications encompass the overall requirements for a project, which can include various types of specifications but are broader than just the design aspects. Understanding this distinction is essential for proper project execution and quality control.
