Elements and Performance Criteria
- Evaluate geological formation of rocks and their subsequent weathering to form various soil types.
- Read and evaluate both topographical and geological maps.
- Identify soil types and their behaviour.
- Determine suitability of foundation soils to support various types of structures.
- Meaning of total and differential settlement of a building is interpreted without error.
- Factors influencing settlement and the ultimate bearing capacity of the ground are interpreted.
- Total and net pressure on foundation soils due to the load of a structure is calculated to determine suitable foundation systems.
- Identify and apply the various methods and applications of soil testing.
- Australian standard laboratory testing of permeability, strength, consolidation and point load tests (for rocks) is identified and interpreted.
- Australian standard for carrying out sub-soil investigations and in situ testing is identified and interpreted.
- Soil testing methods are selected and applied or accessed through competent agencies.
- Determine footing systems for the site conditions and building type.
- Mechanism of soil shrinkage and swelling is interpreted.
- Site classification for the design and construction of a footing system for a single storey dwelling is in accordance with the BCA.
- Application of footings and geomechanical principles for the footing system for a domestic scale building is determined in accordance with BCA and adherence to legislative requirements.
- Determine site maintenance requirements necessary to minimise long-term damage to the structure.
