Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit's learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
*a candidate must meet the performance criteria of this unit by constructing a fire brick wall and arch. This work may include a 230mm fire brick wall to incorporate an opening (600mm x 600mm) with a segmental arch above, a minimum of 1.5m long and 1.2m high to the top of the arch.
In doing this, the candidate must:
*demonstrate understanding of the purpose and application of refractory bricklaying
*comply with Work Health and Safety (WHS) regulations applicable to workplace operations
*use safe and effective procedures to handle hazardous materials
*read and interpret two-dimensional refractory plans and specifications
*select and use processes, tools and equipment appropriate to the job requirements
*prepare materials and samples in accordance with job requirements
*identify typical faults and problems with materials and equipment that occur and take necessary action to rectify
*communicate effectively with others to ensure safe work site operations.
Students will also be expected to demonstrate the following knowledge:
*Building Code of Australia (BCA) and other Australian standards relevant to the nature of work and materials being used
*characteristics and applications of different materials used in refractory brick work:
- header bond
- stretch bond
- metal props
- timber toms
- timber wedges
*wedge shape bricks include the following common sizes:
*methods and processes relating to the use of refractory bricks and insulation materials for the construction of fire resistant structures:
*measurements and placements:
*accurate positioning and maintenance of the centreline of the key brick is through the vertical centre line of the arch ensuring:
- all bricks are cut and laid to maintain even joints
- even joint thickness around the extrados
*organisational procedures for the acquisition and storage of materials
*workplace and equipment safety requirements, including relevant statutory regulations, codes and standards.
