Why Ground Should Be Correct Before Topsoil
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.
Machine Before - Dugong - Machine After
The machine before Dugong determines what material arrives; the machine after Dugong determines what surface must leave. An excavator can expose formation, a loader can deliver a stockpile, and a roller can compact the placed layer. The scraper's role is bounded by those interfaces.
Before moving material
Identify the upstream operation and its remaining defects.
Receiving operation and checks
Hand over the measured surface to compaction, cultivation, paving or turf preparation. Record which operation owns levels, materials and final acceptance.
The workflow can include Dugong where suitable; it does not assume Dugong replaces adjacent equipment.

Uneven ground can combine ridges, ruts and broad changes in slope. A smoothing pass may hide small defects while leaving the underlying geometry wrong.
Before moving material
Survey the scale and distribution of unevenness.
Receiving operation and checks
Verify the changed zones before finishing the entire area. Check both individual deviations and continuity between them.
Do not assume a single uniform plane is the correct outcome.

Hard ground is an operating condition that may limit cutting and traction. It does not justify forcing a deeper pass with an unsuitable tractor or implement.
Before moving material
Identify the material, moisture and buried-obstruction risk.
Receiving operation and checks
Grade the loosened workable material and check the resulting layer. Observe traction, blade response and whether the intended soil layer is being disturbed.
Rock, cemented material or deep excavation may need entirely different plant.
