Conduct commercial and structural re-glazing

This unit of competency covers the skills and knowledge required to replace glass in commercial, structural and/or architectural engineered applications.

Application

This unit requires individuals to demonstrate some discretion, judgement and problem solving in the handling, installation and re-glazing of commercial glass products. The work can be performed individually or in a team environment, with general supervision, and may be part of a production process.

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

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 Required

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.
