Which document shows the design and scale for a residential project?

• A. Specification sheet
• B. Change order
• C. Plan and scale drawings
• D. Bill of materials

Answer: (C)

Showing the design and size of a residential project is done through plan and scale drawings. These drawings provide a visual layout—floor plans, elevations, and sections—and include exact measurements at a standard scale (for example, 1/4 inch equals 1 foot). This combination communicates both how the space is arranged and how big each element will be, which is essential for planning, permitting, and construction.

A specification sheet focuses on materials, finishes, and performance criteria rather than overall size or spatial relationships. A change order records alterations to scope, schedule, or cost after work has started. A bill of materials lists quantities of materials needed, not the design or scale of the project.
