List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. | Prepare for stormwater system set-out. | 1.1. | Project and client requirements for stormwater system are identified and interpreted. |
| 1.2. | Relevant plans, maps and stormwater specifications are accessed and analysed to identify principal work activities. |
| 1.3. | Equipment is selected and prepared according to manufacturer specifications and organisational requirements. |
| 1.4. | Work is planned in consultation with appropriate persons to meet survey specifications and timeframes. |
| | | |
2. | Use control techniques for set-out. | 2.1. | Horizontal control points are located throughout the work area and coordinates are set out according to plans and specifications. |
| 2.2. | Design points are set out from base lines by offsetting, and positions are checked to ensure correct tolerances according to specifications. |
| 2.3. | Primary and secondary controls are used and accuracy is checked according to plans and specifications. |
| 2.4. | Set-out pegs or markers are used to indicate base lines and offsets relative to the work area. |
| 2.5. | Vertical control points are established to ensure design points are positioned at correct levels according to plans and specifications. |
| 2.6. | Offsets and profiles are put in place to define the main lines of stormwater works and provide vertical controls. |
| 2.7. | Measured surveying data is reduced and calculations, including fall of land and volume, are conducted according to industry-accepted standards and organisational requirements. |
| | | |
3. | Finalise stormwater system set-out. | 3.1. | Measurements are checked according to plans and specifications to ensure correct plan position and reduced level of set-out. |
| 3.2. | Discrepancies between specifications and actual activities are identified and addressed or reported according to organisational requirements. |
| 3.3. | Stormwater system set-out is finalised and documentation completed according to organisational requirements. |
A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit. The person must also set out stormwater systems and associated engineering structures for two different projects.
While setting out the above stormwater systems and associated engineering structures, the person must:

hand-held laser measuring device
global navigation satellite system (GNSS)
level
tape
total station
use horizontal and vertical control techniques to position design points and markers
measure and calculate data within industry-accepted tolerances for accuracy
