Elements and Performance Criteria
- Perform setting out, measuring techniques and associated calculations.
- Trigonometric and geometric calculations commonly used with grid lines, off sets and right angle triangles are calculated and recorded without error.
- Site set-out procedures are carried out according to standard work methods on sites.
- Errors in measured distances due to site characteristics and measurement methods are identified and explained.
- Cut and fill calculations are conducted without error.
- Set up and use levelling devices.
- Use of levelling device is demonstrated in accordance with standard operating procedures.
- Error present in a level by the 'two peg test' device is demonstrated in accordance with standard operating procedures.
- 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.
- Calculation of staff readings to enable a specific reduced level (RL) set-out to be determined is calculated without error.
- Mark out and determine levels on a grid for contouring and volume calculations.
- Construct longitudinal sections and determine associated grades and levels in typical drainage and pipeline situations.
- Longitudinal sections are drawn from reduced levels and running chainages.
- Levels and clearances from given grades and distances are determined to specified tolerances.
- Calculations and expressions of grades in three forms are determined to specified tolerances.
- Calculations for batter levels from grades and distances are determined without error.
