Application
This unit requires the operator to plan the work, conduct routine checks, check controls, set up and prepare for operation, deliver concrete, and shut down and secure concrete placing boom. This unit is based on the requirements of the National Standard for Licensing Persons Performing High Risk Work. This unit in its current form meets state and territory licensing requirements. Any alteration will result in a unit which is not acceptable to regulators for the purpose of licensing. |

Evidence Required
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 | Successful assessment of this unit meets the competency requirement of the National Standard for licensing Persons Performing High Risk Work. State/Territory OHS regulators have mandated the use of Assessment Instruments and Instructions for Assessment for this unit which have been endorsed by the national body responsible for OHS matters. |
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: comply with OHS licensing legislation assess ground conditions to confirm that the site is suitable (e.g. firm, level and safe) to erect the concrete placing boom. assess risk and hazard control strategies, including hierarchy of control as applied to the positioning and safe operation of the concrete placing boom (particular awareness of the risks associated with overhead powerlines/electrical cables, ground conditions, wind, pedestrians and tipping) complete the pre operational check, positioning, stabilising, set up, operation, post operational checks of a concrete placing boom including all functions to their maximum extension in the moving of the boom and placement of concrete to the safe working rated capacity of the concrete placing boom operate the concrete placing boom in conjunction with other appropriate personnel (where applicable). |
Context of and specific resources for assessment | Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints Assessment is to comply with relevant appropriate standard requirements Applicants must have access to: personal protective equipment (PPE) for the purpose of the Performance Assessment appropriate concrete placing boom and associated equipment in safe condition communication equipment (e.g. two way radios, etc) where appropriate other appropriate personnel to direct the placement of concrete (where applicable). |
Method of assessment | Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application. The use of 'simulators' in the assessment of this unit of competency is not acceptable. Assessment may be in conjunction with the assessment of other units of competency. Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge. Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances. |
Guidance information for assessment | Further information about endorsed Assessment Instruments may be obtained from state/territory OHS regulators. |
