Site evidence
Assemble available ground information, material history, water condition and following construction activity.
Soft ground planning guide
Use this guide to make the project discussion more precise.
Soft ground planning connects soil investigation, treatment objective, working area and construction interface rather than starting from a machine category.
This guide helps prepare a structured CMG equipment discussion for soft or variable ground.

Guide contents
Questions a technical buyer should resolve before selection.
Method fit
Review impact rolling, hydraulic compaction or other project-selected methods against access and work area.
Operational boundary
Saturated, unstable or muddy ground requires site assessment before equipment operation.
Acceptance route
The project engineering process determines how the completed work is accepted.
Evidence boundary
A useful guide is clear about what it does not prove.
CMG uses this resource to organise a project conversation. It does not replace site investigation, geotechnical design, equipment documentation or the project acceptance specification.
- Do not use a soft-ground keyword as a universal equipment claim.
- Do not treat equipment movement as acceptance evidence.
- Review changed moisture or stability before continuing work.
Buyer checklist
Prepare these inputs before sending an RFQ.
- Available ground investigation
- Treatment objective and work area
- Access, drainage and water condition
- Available equipment and programme
- Project acceptance requirements
Decision record
Turn the research question into a reviewable equipment brief.
Use the following record as a handover between procurement, site engineering and the equipment supplier. Empty fields are signals to investigate, not assumptions to fill with a generic machine claim.

Further questions for the project team.
What is the first step for soft ground?
Provide ground information, treatment objective, work area and constraints.
Can CMG select the final method?
CMG can discuss equipment routes; final method and acceptance belong to the project engineering process.
Which products may be relevant?
Impact roller or hydraulic compaction equipment may be considered after project inputs are reviewed.
What should be recorded?
Material, moisture, work zones, changes and the project acceptance route.
