Existing Surface Survey — Road Use
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
Existing-Surface Survey
An existing-surface survey records what is present before soil moves. Omitting a drain edge, bank or abrupt grade change can distort the volume model even when point readings are correct.
Before moving material
Identify the work extent and important surface features.
Receiving operation and checks
Compare the surveyed surface with the proposed design. Inspect coverage and gaps rather than relying only on a coloured map.
Survey spacing must reflect terrain and required precision, not a universal grid size.

Surveying existing ground is the first project-stage record of the surface to be changed. Agree the coverage before the survey so critical features are not omitted.
Before moving material
Define boundaries of work, reference control and required detail.
Receiving operation and checks
Issue the survey with datum, units and limitations stated. Check control-point agreement and representation of abrupt terrain changes.
A survey deliverable should not be confused with a legal boundary determination.

Road corrugations concern both the wearing material and traffic interaction. Dragging loose peaks into hollows can improve appearance temporarily while leaving the cause unchanged.
Before moving material
Assess aggregate condition, drainage and the depth of the corrugated layer.
Receiving operation and checks
Compact and manage traffic as required by the road-maintenance plan. Check that the profile and edge drainage are restored.
Persistent corrugation may need material or maintenance-method changes.
