Irrigation Bay — Fine Grading
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 Surface Handover
An irrigation-surface handover combines measured field geometry with the intended water-control arrangement. Dry-surface checks should be followed by appropriate operating observations where possible.
Before moving material
Confirm the design and inlet/outlet references.
Receiving operation and checks
Record observations during a controlled irrigation event. Compare the observed route with the intended operation.
No water-saving percentage is established without appropriate before-and-after evidence.

An irrigation bay needs a planned relationship between inlet, surface, banks and outlet. Local low areas can retain water while high areas delay its movement.
Before moving material
Record bay dimensions, boundary levels and existing supply/outlet details.
Receiving operation and checks
Recheck levels and observe an irrigation event before declaring the bay complete. Inspect the far end and corners for residual depressions.
No single bay slope or inlet setting suits every soil and water supply.

The surface is the handover between operations. An excavator may finish its excavation, but the roller still needs suitable material, lift thickness and moisture. A scraper may finish shaping, but the irrigation operator still needs a connected fall to a usable outlet. Define acceptance at each transition instead of allowing the next machine to inherit an unresolved problem.
Before moving material
Name the operation that receives the surface and agree its requirements.
Receiving operation and checks
Release the area to the next operation only after outstanding defects are identified. Use independent level checks and project-specific material tests where required.
Visual smoothness alone does not prove compaction, bearing capacity or hydraulic performance.
