How do 'as-built' drawings differ from original design drawings?

• A. They show the exact design as planned by engineers.
• B. They are created by contractor after construction to reflect the actual installed configuration.
• C. They include only future renovations.
• D. They are used for marketing materials.

Answer: (B)

As-built drawings capture what was actually built, not what was planned. After construction, these drawings record the real installed configuration—the exact locations, dimensions, and connections, including any changes, deviations, or field modifications that occurred during the project. This makes them different from the original design drawings, which show the intended layout and specifications before work began. As-built records provide a truthful snapshot of the finished project and are essential for maintenance, future renovations, and accurate facility management. They aren’t used for marketing or limited to future renovations; they reflect the current built condition.
