Elements and Performance Criteria

1. Evaluate glass and glazing work requirements
   • Work health and safety (WHS) requirements for determining glass and glazing requirements are observed throughout the work
   • Glass and glazing job requirements are identified from workplace documentation, client and specialist specifications, and a technical evaluation conducted
   • Confirmed requirements for compliance with glass and glazing standards in the work are recorded according to workplace procedures and requirements
2. Determine application of glass and glazing standards
   • Products/types of glass for the job are identified and product supply sources are examined to ascertain current developments, if appropriate
   • Relevant standards are assessed against job requirements
   • Influencing factors are identified and their significance and impact on the end product determined
   • Professional technical advice is sought, if applicable and available, in accordance with workplace procedures
   • Optimal solution to completion of the work is identified and specifications meeting all applicable standards is confirmed
3. Communicate advice
   • Solution is converted into detailed work instructions/job specifications in accordance with workplace procedures
   • Other documentation, including any advice/referral to client of other building professionals, is completed in accordance with workplace practices
   • Communication with clients, building professionals and other workers is maintained to ensure all work is carried out to comply with glass and glazing standards

stairways

suspended balustrading

sloped or overhead glass

5-star rated buildings

Note, wherever Australia Standards are listed they apply at the time of publication, but the most current version (including amendments) or replacement versions are to be used.

Correctly complete measurements, calculate work requirements, optimise glass sizes for application and assembly of required resources

Use workplace technology, relevant resources and product specifications related to glass and glazing requirements to:

determine glass thickness limitations

assess the impact of glass shape for determining application

identify and calculate aspect ratios

understand and apply the principles of wind loadings

identify glazing situations affected by human impact, including where activity could generate a high risk of breakage, and where glass could be mistaken for a door

determine the appropriate glazing materials, processing and installation methods for various glazing situations, including all types of safety glass

Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures

Avoid backtracking, work flow interruptions or wastage

Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
