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 glaze/reglaze simple/complex windows and doors
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:

metal channel and beaded window sashes including fixed, sliding, double hung, casement and awning sashes
timber putty faced and beaded doors including fixed, sliding, hinged, pivot and bi-fold doors
metal channel and beaded doors including fixed, sliding, hinged, pivot and bi-fold doors

To include the following details for each:

select glass thickness and type in accordance with AS1288
calculate glazing clearance and cutting size
cut glass to AS4667 Quality requirements for cut to size and processed glass
select glazing tools, equipment, glazing sealants, vinyls and tapes
prepare working area
prepare glazing rebates and channels prior to installation
clean glass, tools, equipment and work area
calculate the cost of glass, glazing materials and labour
Reglaze timber and metal windows and doors including
prepare work area and drop sheets
select reglazing tools and equipment
hack out/remove beads and glass safely from timber windows and doors
remove and disassemble metal window sashes and doors and remove glass safely
select glass thickness and type in accordance with AS1288
calculate glazing clearance and cutting size
cut glass to industry standards AS4667
select glazing tools, equipment, glazing sealants, vinyls and tapes
glaze timber and metal windows and doors
install sash cords, unique and spring balances on timber and metal double hung windows
clean glass, tools, equipment and work area
Work effectively with others
Modify activities to cater for variations in workplace contexts and environment

Underpinning Knowledge
The qualities and characteristics of glass, including the hazards and handling requirements
The techniques, methods, materials and process of glazing simple/complex window and door frames
Workplace safety system requirements related to the glazing simple/complex window and door frames
Relevant Australian Standards
Workflow in relation to fitting glass
Characteristics, purpose and operation of tools and equipment used in glazing simple/complex window and door frames
Identification of equipment, processes and procedures

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 limited workplace technology related to the glazing of simple window and door frames

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 glazing equipment, materials, work instructions and deadlines.

Key Competency Levels

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
