Supervise and report on conduit inspections


Application

This unit describes the skills required to supervise or manage the inspection and reporting of the condition and features in sewer and stormwater conduits using specialised CCTV equipment.

This unit applies to those who supervise or manage work involved in the inspection and reporting of the condition and features in sewer and stormwater conduits using specialised CCTV equipment. It is also applicable to people who prepare inspection reports from data supplied by specialised CCTV sewer inspection operators.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to, particularly those related to industry codes and specifications.

Those undertaking this unit would work independently or in a team and the level of responsibility may vary according to the size, scope, location, and technical complexity of process. They would perform complex tasks in familiar contexts while ensuring minimum damage to the environment.

No licensing, legislative or certification requirements apply to unit at the time of publication.


Elements and Performance Criteria

ELEMENTS

PERFORMANCE CRITERIA

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section.

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 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.

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.

3.2 Record asset and inspection data using appropriate software.

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.

3.5 Confirm defects or malfunctioning of maintenance holes, pits or other access structures with the operator and report.

4. Prepare conduit inspection reports for client

4.1 Compile inspection reports and present to the client.

4.2 Follow inspection video and data security procedures.

Evidence of Performance

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

using data capture software

accessing and interpreting conduit details from asset information systems, construction drawings, plans, maps, house service diagrams

identifying inspection reporting requirements in specifications

supervising or managing the inspection and reporting of the condition and features in sewer and stormwater conduits using specialised CCTV equipment

identifying and correctly coding all critical defects and/or features of conduits observable in inspection video records

reading and interpreting a wide range of numerical data from construction drawings, plans, maps and service diagrams

recognising non-compliant video images and data from conduit inspections

interpreting asset information on maps, plans and drawings of the conduit provided by the asset owner/operator/client


Evidence of Knowledge

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.

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


Assessment Conditions

Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
