Unit of competency details

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised  text is used, further information is detailed in the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1 Determine inspection reporting requirements 

1.1 Determine the inspection reporting standard  and special inspection and reporting requirements  of the client or asset owner from specifications and/or instructions.

1.2 Obtain plans and maps of assets  to be inspected and identify relevant asset data.

1.3 Seek clarification of inspection reporting requirements from the client/asset owner for unusual or non-routine inspections.

1.4 Verify the competence of operators undertaking the inspection.

2 Review video images , data and reports from inspections .

2.1 Check video records  of inspections.

2.2 Compile documentation from inspection and check for completeness and accuracy.

2.3 Recognise unsatisfactory video images and other non-compliant data and submit non-compliance reports to the operator.

2.4 Label and reference inspection information according to specifications and/or enterprise procedures.

3 Identify and code defects and other features from video images of conduit inspection .

3.1 Identify and code structural defects, service conditions and other features of the conduit  in accordance with industry code and/or specifications.

3.2 Record asset and inspection data using appropriate software in accordance with industry code and/or specifications.

3.3 Investigate and report unrecognisable defects, service conditions or other features.

3.4 Identify a conduit at risk of imminent failure and communicate details to the system operator/asset owner according to operational procedures .

3.5 Confirm defects or malfunctioning of maintenance holes, pits or other access structures with the operator and report in accordance with industry code and/or specifications.

4 Prepare conduit inspection reports for client .

4.1 Compile inspection reports  and present to the client in the format required by the industry code/specifications or enterprise practice.

4.2 Follow inspection video and data security procedures  in accordance with the specifications and or enterprise procedures.

This describes the essential skills and knowledge and their level, required for this unit.

Required skills :

• identify structural defects, service conditions and other features in a range of different conduits
• apply industry inspection reporting code requirements
• use data capture software
• access and interpret conduit details from asset information systems (GIS), construction drawings, plans/maps, house service diagrams
• identify inspection reporting requirements in specifications
• interpret policies, procedures and standards
• communicate with clients and operators

Required knowledge :

• industry inspection reporting code
• data capture, recording and reporting software
• asset information systems
• operational plans/maps
• design plans for construction
• features of conduits used in Australia or operating area for gravity sewer and stormwater construction over the last 100 years
• construction and operation of sewerage and stormwater systems

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The candidate should demonstrate the ability to supervise or manage the inspection and reporting of the condition and features in sewer and stormwater conduits using specialised CCTV equipment Including:

• identifying and correctly coding all critical defects and or features of conduits observable in inspection video records
• recognising poor quality, inaccurate and other non-compliant video images and data from conduit inspections
• interpreting correctly all relevant asset information on maps, plans and drawings of the conduit provided by the asset owner/operator/client

Context of and specific resources for assessment 

Access to the workplace and resources including:

• documentation that should normally be available in a water industry organisation
• relevant codes, standards, and government regulations

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

• competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
• where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
• a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts
• all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
• where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
• assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.
