Operate and maintain locks and weirs

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills required to regulate flows through the weir and operate the lock gates.

This unit applies to those working as field staff with the responsibility for operating locks and weirs in remote locations.

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.

Those undertaking this unit will work independently under indirect supervision while performing routine tasks in a range of familiar contexts.

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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. Plan and prepare work

1.1 Assess upstream flow and establish pool demand.

1.2 Carry out inflow calculations.

1.3 Determine discharge flows.

1.4 Develop operation and maintenance plan.

2. Operate locks and weirs

2.1 Operate the weir gates to control river flows and pool levels.

2.2 Store water in the weir pool and regulate river flow downstream.

2.3 Raise river level upstream of the weir to improve navigability of the river.

2.4 Operate the lock to allow river vessels to navigate through the weir.

3. Maintain locks and weirs

3.1 Inspect the equipment of the locks, weirs and navigational aids to identify maintenance needs.

3.2 Schedule maintenance tasks.

4. Finalise work

4.1 Collect data from monitoring points.

4.2 Compile reports from monitoring point data.

4.3 Identify and report current or potential problems.

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.

installing stop logs, bulk heads and winch operations

identifying and investigating operational problems

regulating flows through the weir

operating the lock gates

operating lock levels

calculating inflows and discharge rates

undertaking maintenance including at least one of:

removing debris

oiling hydraulics

repairing concrete

painting metal work

greasing bearings

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.

environmental considerations

river hydraulics

navigational rules

legislation relating to vessels within locks

materials characteristics including:

concrete

steel

hydraulic systems

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.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
