Irrigation Designer — Survey Handover

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.

Irrigation Grade Design

Irrigation grade design starts with the method of applying water and the field's soil and supply conditions. Minimising unnecessary soil movement is one consideration alongside water distribution.

Before moving material

Survey the field with inlet and outlet structures.

Receiving operation and checks

Check the formed field and its operating behaviour. Record levels and water observations together.

A single published slope cannot replace site-specific irrigation design.

Survey Existing Ground

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.

Survey & Verify

Survey and verification compares the delivered surface with the brief before it is covered by the next layer. It should establish both compliant areas and defects.

Before moving material

Agree the acceptance method and reference.

Receiving operation and checks

Record accepted work and required corrections. Check the issued design revision and datum used for comparison.

A level survey cannot prove compaction, and a density test cannot prove grade.

Record the job inputs

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.

Existing condition, extent and the reason for intervention
Required finished purpose, receiving operation and acceptance criteria
Material type, layer role, source, receiving area and volume state
Reference levels, datum, survey method and issued design revision
Available tractor, implement configuration, travel route and turning space
Checks before work, stopping points and evidence retained at handover

Checklist ticks apply only while this page is open. Include the completed brief in your project records.
