Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Plan and prepare. |
1.1. Work instructions, including plans, specifications, quality requirements and operational details, are obtained, confirmed and applied from relevant information . 1.2. Safety (OHS ) requirements are followed in accordance with safety plans and policies. 1.3. Signage and barricade requirements are identified and implemented. 1.4. Tools and equipment selected to carry out tasks are consistent with job requirements, checked for serviceability, and any faults are rectified or reported prior to commencement. 1.5. Material quantity requirements are calculated in accordance with plans, specifications and quality requirements . 1.6. Materials appropriate to the work application are identified, obtained, prepared, safely handled and located ready for use. 1.7. Environmental requirements are identified for the project in accordance with environmental plans and statutory and regulatory authority obligations, and are applied. |
2. Conduct levelling procedures using rise and fall method. |
2.1. Instrument is accurately set up and tested for operation before commencing levelling activities . 2.2. Datum point is set up or located. 2.3. Readings are taken to datum and at nominated or selected stations, to project specifications. 2.4. Backsights, intermediate sights and foresights are identified and levels are booked. 2.5. Instrument is transferred to another location and the process is repeated to project specifications. 2.6. Accuracy of readings is established using rise and fall method of calculation. 2.7. Reduced levels for all stations are identified from the level book calculations. |
3. Conduct levelling procedures using height of instrument method. |
3.1. Instrument is accurately set up and tested for operation before levelling , including levelling equipment /device tolerance checks . 3.2. Datum point is set up or located. 3.3. Level readings are taken to datum and the interim reduced level is established. 3.4. Readings are taken at nominated or selected stations to project specifications. 3.5. Instrument is transferred to another location and the process is repeated to project specifications. 3.6. Reduced levels are calculated using height of instrument method. 3.7. Reduced levels for all stations are identified from the calculations and heights and levels recorded . |
4. Calculate distances using stadia lines. |
4.1. Cross hair readings are checked for accuracy using stadia lines. 4.2. Distances are calculated from instrument to stations using staff, stadia lines and identified factor of the levelling instrument. |
5. Clean up. |
5.1. Work area is cleared and materials disposed of, reused or recycled in accordance with legislation, regulations, codes of practice and job specification. 5.2. Tools and equipment are cleaned, checked, levelling devices maintained and stored in accordance with manufacturer recommendations and standard work practices. |

Evidence Guide
EVIDENCE GUIDE |
|
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. |
|
Overview of assessment |
This unit of competency could be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
|
Context of and specific resources for assessment |
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints. Assessment of essential underpinning knowledge will usually be conducted in an off-site context. Assessment is to comply with relevant regulatory or Australian standards' requirements. Resource implications for assessment include:
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support. |
Method of assessment |
Assessment methods must:
Validity and sufficiency of evidence requires that:
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed. Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff. |
