Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

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

Elements and Performance Criteria

1

3.2

Other on-site difficulties are recognised and corrective action taken in accordance with regulations and glazing requirements

3.3

Covering material is applied, where necessary, to protect existing fixtures and fittings

3.4

Special characteristics of the window or door which may affect the finished job are identified and corrective action taken

4

Prepare frame and materials

4.1

Frame condition (if applicable) is assessed to ensure suitability for re-glazing in accordance with customer requirements and Australian Standards

4.2

Defective frames are reported for repair or replacement in accordance with workplace procedures

4.3

Frame is prepared  (if required) to receive glass

4.4

Fixing and sealing materials are prepared by mixing or cutting to length, as appropriate

5

Fit glass

5.1

Glass is fixed to the frame using the selected method and in accordance with recognised industry procedures and Australian Standards

5.2

Solvents and sealants are used in accordance with manufacturer recommendations and Australian Standards

5.3

Excess sealing material is removed and glass and frame cleaned after fixing

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills include: 

  • collecting, organising and understanding information related to work orders, basic plans and safety procedures
  • using communication skills to the level required to confirm work requirements and specifications; communicate effectively regarding work requirements with supervisors, other workers and customers; report work outcomes and problems; and relate to people from a range of social, cultural and ethnic backgrounds, and of varying physical and mental abilities
  • using literacy skills to the level required to understand information related to work orders, including common industry terminology, plans and safety procedures; prepare reports; and interpret technical information and specifications
  • planning and organising activities, including the preparation and layout of the work area, and the obtaining of equipment and materials to avoid any backtracking, workflow interruptions or wastage
  • working with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
  • using mathematical ideas and techniques to correctly complete measurements, calculate work requirements, and optimise glass sizes for economical cutting and assembling of required materials
  • using pre-checking and inspection techniques to plan work, and avoid re-working and wastage
  • using workplace technology related to commercial and structural re-glazing
  • modifying activities to cater for variations in workplace contexts and environment

Required knowledge includes: 

  • types, qualities and characteristics of glass, including hazards and handling requirements
  • relevant Australian Standards
  • techniques, methods, materials and process of commercial and structural re-glazing
  • workflow requirements in relation to fitting glass
  • the correct application and operation of tools and equipment used
  • identification of equipment, processes and procedures
  • types of silicone products and their use
  • workplace safety system requirements related to commercial and structural re-glazing
  • regulations and standards for safe working at heights and on scaffolding

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

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

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

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

  • interpret work order/job instruction and locate and apply relevant information to conduct commercial and structural reglazing
  • apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
  • follow work instructions, operating procedures and inspection practices to:
  • minimise the risk of injury to self and others
  • prevent damage to glass, frames, equipment and products
  • maintain required product quality
  • as a minimum:
  • safely remove glass from commercial and architectural frames
  • prepare frame and opening, including clean-up
  • measure glass for commercial projects, doors, show and/or food cabinets, including sliding tracks, shop fronts and returns, architectural, curtain wall, structural and/or overhead glazing
  • selecting glass to comply with AS 1288:2006 Glass in buildings - Selection and installation
  • cutting and processing glass in accordance with AS/NZS 4667:2000 Quality requirements for cut-to-size and processed glass
  • identify and work at heights and on scaffolding to the relevant regulations and standards
  • identify and apply glazing, structural sealants and tapes
  • calculate the cost of glass and labour
  • work effectively with others.

Context of and specific resources for assessment

  • The application of competency is to be assessed in the workplace or realistically simulated workplace.
  • Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints.
  • Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context.
  • Assessment is to comply with relevant regulatory or Australian Standard requirements.
  • The following resources should be made available:
  • frames
  • glass
  • fixing material
  • sealants
  • workplace operating procedures and work orders
  • personal protective equipment
  • an appropriate work area/site.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the LMF02 Furnishing Industry 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 able not only 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.
