Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Perform setting out, measuring techniques and associated calculations. |
1.1. Trigonometric and geometric calculations commonly used with grid lines, off sets and right angle triangles are calculated and recorded without error. 1.2. Site set-out procedures are carried out according to standard work methods on sites . 1.3. Errors in measured distances due to site characteristics and measurement methods are identified and explained. 1.4. Cut and fill calculations are conducted without error. |
2. Set up and use levelling devices. |
2.1. Use of levelling device is demonstrated in accordance with standard operating procedures. 2.2. Error present in a level by the 'two peg test' device is demonstrated in accordance with standard operating procedures. 2.3. Reduction in a closed level run by rise and fall method and by height of plane of collimation (HPC) method is carried out in accordance with standard practices. 2.4. Calculation of staff readings to enable a specific reduced level (RL) set-out to be determined is calculated without error. |
3. Mark out and determine levels on a grid for contouring and volume calculations. |
3.1. Set out grid and levels are determined. 3.2. Contour plans are prepared from grid levels to specified tolerances and stated contour intervals. 3.3. Volume of solids and the surface being levelled and contoured are determined to specified tolerances. |
4. Construct longitudinal sections and determine associated grades and levels in typical drainage and pipeline situations. |
4.1. Longitudinal sections are drawn from reduced levels and running chainages. 4.2. Levels and clearances from given grades and distances are determined to specified tolerances. 4.3. Calculations and expressions of grades in three forms are determined to specified tolerances. 4.4. Calculations for batter levels from grades and distances are determined without error. |

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 by the application of survey and site set-out procedures and principles of selection and use of two levelling devices to survey and set out building projects. This unit of competency can 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. |
