What is a primary purpose of as-built (record) drawings in project closeout?

• A. It records the intended design.
• B. It predicts future growth.
• C. Documented actual constructed condition of facilities, features, and site improvements.
• D. It identifies the engineer's name.

Answer: (C)

The main idea is that as-built drawings capture what actually exists after construction. They reflect the final geometry, locations, materials, and elevations of facilities, features, and site improvements, including any field changes, substitutions, or adjustments made during building. This creates an accurate record for operations, maintenance, and future modifications, and it helps verify that the installed system meets the permit requirements and design intent in practice. In stormwater projects, knowing the true invert elevations, outfall locations, pipe sizes, and drainage features is essential for ongoing performance, inspections, and updates. The other options describe plans or predictions or metadata, not the actual completed condition, so they don’t serve the closeout and long-term reference purpose as effectively.
