The hook
As-built surveys document what was actually constructed — never identical to the design. The deliverable becomes the official record for the owner, the basis for future maintenance, and a prerequisite for any expansion or sale.

Concepts that show up on the exam
As-built deliverable
Survey of constructed features (buildings, utilities, pavement, drainage). Compared against design; deltas annotated.
Design vs. as-built deltas
Documented per feature: vertical, horizontal, geometric. Tolerances vary by feature type and project spec.
Subsurface utility documentation
Often required for buried utilities — locations, depths, sizes, materials. Quality Levels A (dig + survey) through D (records review).
Vertical positioning
For surfaces (paving, slabs, drainage), elevations are spot-checked at standard locations. Tolerance per project spec.
