Earthworks Inspection & Test Plan
Comprehensive ITP for excavation, filling, compaction, and subgrade preparation aligned to Australian standards.
About Earthworks ITPs
Earthworks form the foundation of most civil construction projects. A comprehensive Inspection and Test Plan ensures that excavation, filling, and compaction activities meet specification requirements and Australian standards.
Key activities covered by earthworks ITPs include:
- Site clearing and grubbing
- Excavation to design levels
- Foundation preparation and proof rolling
- Fill material sourcing and approval
- Layer placement and compaction
- Moisture conditioning
- Density testing and verification
Applicable Standards
Earthworks ITPs typically reference:
- MRTS04 - General Earthworks (Queensland)
- AS 1289 - Methods of testing soils for engineering purposes
- AS 3798 - Guidelines on earthworks for commercial and residential developments
- State-specific specifications (TMR, TfNSW, DoT, Main Roads WA)
Typical Hold Points
| Activity | Verification Method | Standard |
|---|---|---|
| Excavation to level | Survey check, visual inspection | MRTS04 |
| Foundation inspection | Proof roll, density testing | MRTS04 |
| Fill material approval | Material testing, source approval | MRTS04 |
| Layer compaction | Density testing (sand replacement/nuclear) | AS 1289 |
| Final levels | Survey, tolerance check | Project spec |
