Unit Descriptor
Unit descriptor |
This unit of competency cover the use of the gunite/shotcrete technique to apply refractory materials. The refractory may be applied by wet or dry processes.. |
Application of the Unit
Application of the unit |
This unit of competency applies to operators who are responsible for using the shotcrete technique to apply refractory materials. Shotcrete is often referred to by trade name of gunite and so the process is sometimes referred to as guniting. It involves setting out work, installing and applying guniting materials, assembling and operating guniting equipment, and removing and reinstating guniting materials. It includes the use of tools and ancillary equipment. Shotcrete work may be the total requirement for the job, or it may need to join to brick/block, moulded or cast refractory. This competency will typically be performed by a team of operators working under direction and to a specification and/or procedures. |

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 |
The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. Consistent performance should be demonstrated. In particular look to see that:
|
Context of and specific resources for assessment |
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation. Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions. |
Method of assessment |
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units. It may be appropriate to assess this unit concurrently with other relevant units |
Guidance information for assessment |
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed. |
Range Statement
RANGE STATEMENT |
|
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
|
Procedures |
All operations are performed in accordance with standard procedures and work instructions |
Shotcrete |
Shotcrete is the generic term used to describe the placement of cementitious products such as

Occupational health and safety (OHS ) |
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence |
