Subgrade Preparation — Material Movement
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.
Controlled Soil Movement
Controlled soil movement is deliberate placement of suitable material from a defined source to a defined receiving area. The route and load should support that plan.
Before moving material
Identify usable source material and destination levels.
Receiving operation and checks
Grade and prepare the receiving layer. Check the destination and quantity as well as the cut location.
An implement cannot make unsuitable material suitable merely by transporting it.

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.

Establishing the required surface converts a desired use into a construction brief. It should name geometry, layer roles and evidence needed before the next operation.
Before moving material
Identify the receiving operation and relevant design inputs.
Receiving operation and checks
Issue a coordinated brief to the grading and downstream teams. Check interfaces with buildings, roads, drains and neighbouring work.
An illustrative concept is not a construction specification.

Use this checklist to turn the scenario into a specific brief. Retain the design revision and agree who accepts each completed layer.
Checklist ticks apply only while this page is open. Include the completed brief in your project records.
