Modify mechanical systems and equipment

Assessment tool

Version 1.0
Issue Date: May 2024


This unit applies to significant modifications to plant and equipment that lead to desired changes in performance. Maintenance schedules are required for mechanical machines and systems, including stationary, stand-alone machines, and manual, semi-automatic and automatic process systems. This unit applies to existing equipment or the installation of new or replacement equipment.

Where drafting skills to Australian Standard 1100 are required, see Unit MEM09003B (Prepare basic engineering drawing).

Where minor modifications are required, see Units MEM18055B (Dismantle, replace and assemble engineering components) or MEM18006C (Repair and fit engineering components)

Where balancing equipment is required, Unit MEM18008B (Balance equipment) should also be selected.

Band: B

Unit Weight: 8

This unit covers determining the requirements of the modification, undertaking the modification and evaluating the modified mechanical system/equipment.

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.

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 modify mechanical systems and equipment. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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

Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.

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, that is the candidate is not in productive work, 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.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with modifying mechanical systems and equipment or other units requiring the exercise of the skills and knowledge covered by this unit.

Method of assessment

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Guidance information for assessment

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

(add new lines for each of the assessment tasks)

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.

Required skills

Look for evidence that confirms skills in:

obtaining, reading, interpreting and following information on relevant maintenance reports, production data, drawings, circuits, condition monitoring data, specifications, instructions, etc.

analysing reports and other relevant information

developing and planning corrective action plans

inspecting plant/equipment for correct location, alignment, operation, performance and conformance to specifications

documenting and approving planned modifications

preparing and authorising drawings of the modified components and/or sub-assemblies

recording approved modifications undertaken

operating and monitoring performance of modified plant/equipment to ensure conformance with the required performance specifications

reporting/recording efficiency/effectiveness of the modifications undertaken

recommending further modifications to the plant/equipment

Required knowledge

Look for evidence that confirms knowledge of:

the desired changes in performance of the plant/equipment

the specifications of the plant/equipment and its performance requirements

the procedures for inspecting the plant/equipment against specifications

where appropriate, defective components, sub-assemblies and design faults

the effect of defective components, sub-assemblies and design faults on the performance of plant/equipment

the action to be taken to achieve the desired changes in performance

the reasons for taking the action identified

the procedures for documenting the proposed modifications to the plant/equipment

the authority from whom approval to undertake the proposed modifications is to be obtained

typical part failure modes and the causes

the action to be taken to correct part failures and design faults

for given part failures and/or design faults, the options for modifying the plant/equipment

for given components and/or sub-assemblies, appropriate standard replacements from manufacturers'/suppliers' catalogues

the procedures for modifying drawings of components and/or sub-assemblies

the procedures for authorising changes made to drawings of plant/equipment

the procedures for recording modifications undertaken

the procedures for checking the operation of the modified plant/equipment against required performance specifications

procedures to report/record the effectiveness/efficiency of the modifications

the tests to be undertaken to check the performance of the modified plant/equipment

engineering design and drawing skills associated with modifying mechanical systems and equipment

numerical operations, geometry and calculations/formulae within the scope of this unit

hazards and control measures associated with modifying mechanical systems and equipment

use and application of personal protective equipment

safe work practices and procedures

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.

Analysed

Interpretation and integration of data from consultations, process control instrumentation and condition monitoring systems, etc.

Modifications

Changes to plant and equipment which lead to desired changes in performance

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.
