Application
This unit describes a participant’s skills and knowledge required to apply shot-crete underground in Civil Construction and Metalliferous Mining.
This unit is appropriate for those working in operational roles.
Licensing, legislative, regulatory and certification requirements that apply to this unit can vary between states, territories, and Industry sectors. Relevant information must be sourced prior to application of the unit.
Elements and Performance Criteria

2. Apply shot-crete | 2.1 Prepare and clean targeted surface to ensure maximum cohesion of shot-crete 2.2 Erect barriers 2.3 Minimise the creation of gases and personnel exposure to fumes according to safe shot-creting processes 2.4 Select and apply shot-crete utilising appropriate application method according to manufacturer’s guidelines and ground condition |
3. Conduct housekeeping activities | 3.1 Maintain barriers/signs after shot-creting 3.2 Complete all required documentation clearly, concisely and on time 3.3 Clean equipment, ascertain condition of equipment and ensure safe and efficient operations 3.4 Pass on end of shift information to oncoming shift |
Evidence of Performance
Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:
locates and applies relevant documentation, policies and procedures
demonstrates completion of the application of shot-crete underground that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:
applying hydroscaling techniques to clean and remove skate prior to shot-creting
completing equipment pre-start checks
inspecting and assessing ground control mechanism
preparing and cleaning the targeted surface
erecting barriers
selecting and applying shot-crete
Evidence of Knowledge
The candidate must demonstrate knowledge in applying shot-crete underground through:
dewatering procedures and characteristics
environmental procedures
equipment safety requirements
ground control characteristics and applications
explosive identification
shot-creting techniques
Assessment Conditions
An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
this unit is best assessed in the context of this sector’s work environment;
where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; and,
this unit must 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,
assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:
Industry sector | AQF** Level | Required assessor or Industry subject matter expert experience |
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction | 1 | 1 Year |
2 | 2 Years | |
Drilling, Coal Mining and Extractive (Quarrying) | 3-6 | 3 Years |
Metalliferous Mining and Civil Construction | 3-6 | 5 Years |
Other sectors | Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation. | |
*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 frequent site assessments across various locations.
**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
