Compaction Preparation — Design
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.
Compaction Preparation
Compaction preparation concerns material condition, layer thickness and access as well as grade. A roller cannot reliably correct poorly placed or unsuitable fill merely by making more passes.
Before moving material
Obtain the project's material and compaction requirements.
Receiving operation and checks
Use the appropriate compactor and testing procedure. Check that the layer remains continuous and accessible for the compaction plant.
There is no universal pass count or density target for every material.

A drawing becomes useful in the field when its levels, coordinates and version are understood by the people and equipment doing the work. A design may be correct while the machine follows the wrong datum or an outdated file. Resolve that transfer before soil moves.
Before moving material
Agree the coordinate system, vertical datum, benchmark and drawing revision.
Receiving operation and checks
Record changes and return the verified surface information to the designer. Retain the issued design and the as-built check as separate records.
Do not infer a surveyed boundary or certified design from an illustrative terrain model.
Read the complete Design to Dirt guideDrainage Grade Design
Drainage grade design must connect the contributing area to a suitable outlet. Selecting a numerical fall before checking the outlet can produce a surface that cannot discharge as intended.
Before moving material
Survey entry points, structures and the receiving level.
Receiving operation and checks
Inspect the constructed route and its transitions. Check invert continuity and controls at crossings.
This guide does not size drains or establish discharge permissions.
