Elements and Performance Criteria

The Range Statement provides advice to interpret the scope and context of this unit of competency, allowing for differences between enterprises and workplaces. It relates to the unit as a whole and facilitates holistic assessment. The following variables may be present for this particular unit:

Glass and glazing assessment
Glass and glazing assessment involves the assessment required for all glass and glazing tasks. It may be a formal and documented process or an informal on-the-job assessment of a situation/requirement.
Factors which may influence the assessment include:

residential and commercial applications

building height/limitations

wind loading considerations

regional boundaries/zones

terrain description/categories

human impact considerations

Unit context

OH&S requirements may include legislation, standards, building codes, material safety management systems and local safe operating procedures

Work is carried out in accordance with statutory requirements, environment legislation, manual handling procedures and relevant regulations and organisation insurance requirements
Work requires individuals to demonstrate discretion, judgement and problem solving skills in the planning, setting up and freefalling of glass from a rack to a table

Work may be performed in workplaces which are involved in the manufacture, processing and/or installation of sheet glass

Work is generally performed individually and may be on a one-to-one basis with a customer/supervisor, with only limited supervision and may be part of a production process

Tools and equipment may include:
tape measures
calculators
glass thickness and glazing material indicators
product data and samples
relevant standards/codes
stationery and calculator

Personal protective equipment is to include that prescribed under legislation, regulation and enterprise policies and practices. It may include:
gauntlets
gloves
safety glasses
hard hats
safety footwear
aprons and overalls

Information and procedures
Work procedures/instructions relating to assessment of glass and glazing requirements
Regulatory/legislative requirements, particularly those pertaining to building codes, OH&S and environmental requirements
Manufacturers' specifications and instructions, particularly those pertaining to new products/developments
Organisation work specifications and requirements
Authorised organisational or external personnel
Australian standards: AS1288, 2208, 1170.2, HB125
Workplace experience/expertise and previous projects/work

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 glass and glazing requirement and accurately determine solutions to meet work situations/customer queries
Identify and confirm requirements/customer expectations
Locate, interpret and apply information for situation to be assessed
To complete a minimum of:
apply the requirements of AS1288 (requires an understanding of scope, definitions, abbreviations and symbols)
determine thickness limits for standard nominal thickness of glass
identify and calculate aspect ratios
identify regional boundaries, terrain categories and their description
determine minimum nominal glass thicknesses for various glazing situations using wind loading design charts and tables
identify types of safety glazing materials
determine the safety glazing materials for various glazing situations
determine safety glazing material thicknesses from flow charts
identify basic installation details for glazing
identify the design considerations and glazing techniques for toughened glass assemblies
Work effectively with others
Modify activities to cater for variations in workplace cultures and environment

Underpinning Knowledge
Workplace operating procedures and AS1288
The qualities and characteristics of glass, including types, qualities, applications and limitations
Products and processes and current trends and developments in glass and glazing techniques/applications
Workflow and operating requirements of work systems in own work area
Workplace safety system requirements related to the handling and installation of glass

Underpinning Skills
Information. Collect, organise and understand information related to glass and glazing, 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 information and reference materials to facilitate assessment, avoid workflow interruptions and assist efficacy of solutions
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 application and assemble required resources
Solve problems. Apply knowledge, analytical skills and tools to assist in the assessment of glass and glazing requirements to plan work, providing effective and acceptable solutions
Use of technology. Use the workplace technology related to the assessment of glass and glazing requirements

Resource Implications
Work requirements, workplace operating procedures, personal protective equipment and an appropriate work area.

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 simulated workplace facility with relevant glass and glazing requirements, simulated work instructions and commitments.

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
