Which drawings document the actual constructed configuration?

• A. Shop drawings
• B. Design drawings
• C. As-built drawings
• D. Working drawings

Answer: (C)

Documenting the actual built configuration is captured in as-built drawings. These drawings record what exists in the field after construction, including any deviations from the plans, changes in alignment, depths, valve locations, fittings, and materials. They provide an exact, up-to-date record of the finished system, which is essential for future maintenance, tie-ins, expansions, and regulatory compliance.

Shop drawings show how components will be fabricated or assembled to meet the design, design drawings present the designer’s intended plan, and working drawings are the detailed build-ready drawings used during construction. As-built drawings stand apart by reflecting the real, constructed configuration rather than the original intent or the process of building.
