- conducting preoperational procedures and confirming waste management procedures
- completing housekeeping activities
- work with others to conduct vacuum excavation that meets required outcomes, including:
- organising work activities to meet task requirements
- communicating with others to receive and clarify work instructions
- using a range of communication techniques and systems
- using signage to advise others of work activity and exclusion zones
- comply with written and verbal reporting requirements and procedures.
Knowledge Evidence
The candidate must be able to demonstrate knowledge to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including knowledge of:
- safety data sheets and materials handling methods
- key risks relating to conducting vacuum excavations, including those associated with:
- traffic
- live electrical services
- operating near other works in progress
- manual handling
- gas
- air excavation
- ground contamination
- nature of material to be excavated
- key policies and procedures, legislation and established requirements for conducting vacuum excavation, including those for:
- workplace health and safety
- notifying asset owners
- environmental protection including potential ground contamination, lawful transport and disposal obligations including re-use and recycling opportunities
- trench and excavation shoring
- site isolation and traffic control
- non-destructive exposure of services and utilities
- asset exclusion zones
- operating and maintaining equipment
- housekeeping activities
- key factors affecting work activities described in performance evidence above, including:
- vacuum excavation techniques
- working in a road reserve
- types of material being excavated
- types of services, utilities and providers
- equipment types, characteristics, technical capabilities and limitations.
Assessment Conditions
Mandatory conditions for assessment of this unit are stipulated below. The assessment must:
- vacuum excavation equipment
- personal protective equipment
- be conducted in a safe environment; and,
- be assessed in context of this sector's work environment; and,
- be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
- confirm consistent performance can be applied in a range of relevant workplace circumstances.
- Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated work environment* provided it is realistic and sufficiently rigorous to cover all aspects of this sectors workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessor Requirements
Assessors must be able to clearly demonstrate current and relevant industry knowledge and experience to satisfy the mandatory competency standards as set out in the Standards for Registered Training Organisations (RTOs) 2015/AQTF mandatory requirements for assessors current at the time of assessment and any relevant licensing and certification requirements. This includes:
- vocational competencies at least to the level being delivered and assessed
- current industry skills directly relevant to the training and assessment being provided
- current knowledge and skills in vocational training and learning that informs their training and assessment
- formal relevant qualifications in training and assessment
- having knowledge of and/or experience using the latest techniques and processes
- possessing a high level of RII training product knowledge
- having an understanding and knowledge of legislations and regulations relevant to the industry and to employment and workplaces
- demonstrating the performance evidence, and knowledge evidence as outlined in this unit of competency, and
- the minimum years of current** work experience after competency has been obtained as specified below in an industry sector relevant to the outcomes of the unit.
It is also acceptable for the appropriately qualified assessor to work with an industry expert to conduct assessment together and for the industry expert to be involved in the assessment judgement. The industry expert must hold the relevant vocational competencies and have current industry skills directly relevant to the training and assessment being provided and must work alongside a trainer and/or assessor to conduct the assessment. This means the industry subject matter expert should hold the unit being assessed (or an equivalent unit), and must also demonstrate skills and knowledge from the minimum years of current work experience after competency has been obtained as specified below, including time spent in roles related to the unit being assessed:

*Guidance on simulated environments has been stipulated in the RII Companion Volume Implementation Guide located on VETNet.
**Assessors can demonstrate current work experience through employment within industry in a role relevant to the outcomes of the unit; or, for external assessors this can be demonstrated through exposure to industry by conducting a minimum number of site assessments as determined by the relevant industry sector, across various locations.
*** While a unit of competency does not have an AQF level, where a unit is being delivered outside of a qualification the first numeric character in the unit code should be considered as the AQF indicator level for assessment purposes.
