commercial windows and doors including: casement, sash, awning and double hung windows, shopfronts and returns, louvres, hinged, pivot and sliding doors and windows, automatic doors, mirrors, furniture applications, showcases, sliding tracks and food cabinets

curtain walls, balustrading, structural and suspended glazing and overhead glazing

May include toughened glass assemblies; aluminium glazing systems including planar assemblies, curtain wall systems, spider assemblies, panel wall systems (hung and stacked); Armourview balustrading; watertight glazing techniques including knowledge of silicone

Quality and Australian Standards and procedures

Equipment and material manufacturers' specifications and operational procedures

Work instructions including job sheets, cutting lists, plans, patterns, templates, drawings and/or designs

Safety standards include personal protective equipment, OH&S regulations and enterprise requirements

Australian Standards

AS1288 Glass in buildings, selection and installation

AS2208 Safety glazing materials in buildings

AS4667 Quality requirements for cut to size and processed glass

The Evidence Guide identifies the critical aspects, knowledge and skills to be demonstrated to confirm competency for this unit. This is an integral part of the assessment of competency and should be read in conjunction with the Range Statement.
Critical Aspects of Evidence
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 production output and product quality

To complete a minimum of:

safely remove broken glass from commercial and architectural frames
prepare frame and opening including cleanup and/or frame repair
measure glass for commercial windows, doors, show and food cabinets including sliding tracks, shop fronts and returns, architectural, curtain wall, structural and overhead glazing
select glass to comply with AS1288
cut and process glass in accordance with AS4667
identify and work with ladders and scaffolding to the relevant regulations and standards
identify and apply glazing, structural sealants and tapes
install and weatherproof glazing materials
calculate the cost of glass and labour
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Underpinning Knowledge
The types, qualities and characteristics of glass, including the hazards and handling requirements
Relevant Australian Standards
The techniques, methods, materials and process of commercial and structural reglazing
Workflow in relation to fitting glass
The application and operation of tools and equipment used
Identification of equipment, processes and procedures
Workplace safety system requirements related to commercial and structural reglazing

Underpinning Skills
Information. Collect, organise and understand information related to work orders, basic plans, and safety procedures
Communication. Communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with work supervisor, other workers and customers, and the reporting of work outcomes and problems
Planning. Plan and organise activities including the preparation and layout of the work area and the obtaining of equipment and materials to avoid any back tracking, workflow interruptions or wastage
Teamwork. Work with others and in a team by recognising dependencies and using cooperative approaches to optimise workflow and productivity
Mathematical ideas and techniques. Use mathematical ideas and techniques to correctly complete measurements, calculate work requirements, optimise glass sizes for economical cutting and assemble required materials
Solve problems. Use pre-checking and inspection techniques to plan work, avoiding reworking and wastage
Use of technology. Use the workplace technology related to commercial and structural reglazing

Resource Implications
Frames, glass, fixing material, sealants, workplace operating procedures and work orders, personal protective equipment and an appropriate work area/site.

Method of Assessment
Assessment methods must confirm consistency of performance over time and in a range of workplace relevant contexts.
Assessment should be by direct observation of tasks and questioning on underpinning knowledge.
Assessment may be in conjunction with assessment of other relevant units of competency.

Context of Assessment
Assessment may occur on the job or in a workplace simulated facility with relevant process equipment, materials, work instructions and deadlines.

Key Competency Levels
NB:These levels do not relate to the Australian Qualifications Framework. They relate to the seven areas of generic competency that underpin effective workplace practices.
There are three levels available:
Level 1 where work is within set conditions and process
Level 2 where the management or facilitation of conditions or process is exercised; and
Level 3 where the design and/or development of conditions or process is required
