What are 'working drawings' used for?

Working drawings serve as critical documents in the construction process, providing detailed information on the specific materials, dimensions, and methods required to construct the project. They translate the design intent into practical instructions that contractors and workers can follow. This includes detailed plans, sections, and elevations that show not only the overall layout but also smaller components like electrical layouts, plumbing details, and structural elements.

By having these precise details outlined in the working drawings, the construction team can ensure that the project is built according to the intended design, complies with local building codes, and adheres to safety standards. They are essential for facilitating coordination among different trades, thereby reducing the likelihood of errors and construction delays. This level of detail in working drawings is what distinguishes them from other types of documents like schematics or conceptual plans, which are less specific and more focused on overall design rather than execution.
