AS 3798 EARTHWORK SERVICES
Plan full-time supervision and testing for controlled fill construction within an agreed Level 1 engagement. Contact us before earthworks begin so inspection coverage, reference testing, reporting and the construction programme can be reviewed.
SCOPE OF OPERATIONS
Inspection coverage includes completion of topsoil removal and relevant preparation before controlled fill placement within the agreed scope.
Notify the team before the relevant stage is covered or work proceeds.
Preparation · test rolling where applicableCompetent personnel provide full-time supervision during applicable earthwork operations, including placement of imported or onsite fill material.
Material source, proposed use and assessment requirements must be agreed.
Imported or onsite fillCoverage includes compaction and addition or removal of moisture, with trenching and backfilling included where applicable to the engagement.
Coordinate the programme so required inspection and testing can occur.
Layer placement · moisture adjustment · compactionCompaction testing may use the nuclear gauge method under AS 1289.5.8.1, with density-ratio assessment against the applicable laboratory reference.
Testing frequency, areas and acceptance criteria must be defined for the project.

COMMON QUESTIONS
Level 1 includes full-time supervision during earthwork operations within the agreed scope and may support a completion statement of compliance. Level 2 is requested testing without full-time supervision or a statement of compliance.
Before earthworks begin. The team needs to review the scope and plan coverage for preparation, material placement, compaction and testing before stages are completed or concealed.
Fill assessment is available, but material information, source, proposed use, specification and sampling arrangements must be reviewed. Arrange assessment before material is placed where possible.
The deliverables depend on the agreed scope and available records. They may include laboratory and field test results, inspection reports and a statement of compliance for the Level 1 earthworks.
