Unit Descriptor

This unit of competency covers the skills needed to apply maintenance engineering techniques to equipment or component modification or repair. It includes decision making on the need for repair, replacement or modification and design of any repair or modification. The unit covers maintenance techniques for repair and modification of mechanical, fluid and electrical plant, and facilities in accordance with procedures, work health and safety (WHS) and legislative requirements, and risk management procedures. Documentation of the repair or modification process includes calculations, specifications, computer-aided design (CAD) files, risk analysis, sustainability and life cycle assessments.

Application of the Unit

This unit applies to maintenance-related work where a technical evaluation must occur on whether to repair, replace or modify equipment or components and where engineering design techniques are applied where repair or modification is required. The unit applies across all engineering disciplines and would normally be selected in conjunction with appropriate technical units for the equipment or components being considered for maintenance.

The unit includes reviewing condition analysis and non-destructive test (NDT) reports. However, the conduct of condition analysis and NDT tests is covered by the relevant specialist technical units.

Where an organisation or whole of plant maintenance management systems is being reviewed or considered for change the unit MEM23125A Evaluate maintenance systems, should be selected.

The unit is suitable for people working at a technician level in maintenance-related design drafting or in maintenance-related supervision or management.

Evidence Guide

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 

A person who demonstrates competency in this unit must be able to apply repair and modification techniques consistent with a design brief information, relevant standards and conventions.

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

Assessors must be satisfied that the candidate can competently and consistently:

  • communicate, negotiate and review maintenance brief with stakeholders
  • determine or confirm scientific principles and design techniques, WHS and regulatory requirements, and design specification requirements
  • evaluate multiple solutions
  • investigate life cycle design, sustainability, technical and professional assistance required, and maintenance alternatives for repairs and modifications
  • plan, schedule and coordinate the maintenance task
  • solve problems and make decisions with systems thinking for contingencies and constraints, and continuous improvement
  • define designs, specify and document and apply graphical techniques, modelling, mock-up or prototyping techniques
  • select components and hardware
  • create and maintain adequate and accurate calculations and design process records
  • report and document results and processes.

Context of and specific resources for assessment 

  • This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.

Method of assessment 

  • Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
  • Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
  • Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
  • Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
  • Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
  • Assessment may be in conjunction with assessment of other units of competency where required.

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.

Systems thinking 

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain
