Elements and Performance Criteria

RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Materials commonly used in swimming pools and spas include:
concrete
fibreglass and plastics
cements
masonry units
mortars
paints and coatings
ceramics
structural steel.
Records of materials tested are kept and reported by:
distributing copies in accordance with organisational policy
following up reports that indicate departures from quality or manufacturing requirements
obtaining appropriate records and reports for review and analysis
proving advice and information to regulatory authorities as authorised by the organisation
taking appropriate remedial action within the scope of individual's authority.
Selected for suitability involves a range of processes including:
analysing reports, manufacturer specifications or other reference material regarding the suitability of new swimming pool and spa building material technologies with reference to BCA requirements
arranging industry standard, external quality tests or inspections and provision of results as necessary
arranging relevant industry standard, on-site quality tests for products to be used in swimming pools and spas
decision making to ensure appropriate materials are selected, including:
identifying materials from specifications and drawings
identifying specifications and standards described in the contract documents
selecting and ordering materials that meet those requirements
arranging for expert advice as necessary to confirm or refute materials options
referencing external reports and manufacturer specifications
refusing acceptance of sub-standard or out of specification materials
seeking expert appraisal from relevant industry professionals, including architects, designers and engineers.
Materials are handled correctly and safely includes:
allocation of space for on-site storage of materials
confirming products or materials are as ordered and signing off delivery documentation
ensuring safe unloading and handling of swimming pool and spa building materials
ensuring safe use of hazardous materials and complying with statutory or regulatory requirements
ensuring correct materials are being delivered to correct site
providing for adequate on-site security of materials
undertaking quality checks within the competence of the individual.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
This unit of competency could be assessed by planning and supervision of a system for selecting, procuring and safely storing all materials required for construction of a swimming pool and spa.
This unit of competency can be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
A person who demonstrates competency in this unit must be able to provide evidence of the ability to:
identify suitable swimming pool and spa building materials specified by the project or contract
use effective verbal and written communication with manufacturers and suppliers of materials
apply effective and efficient testing of the materials to maintain quality standards on site
use effective sampling and record keeping processes
ensure safe handling and storage of materials
comply with organisational and legislative requirements.
Context of and specific resources for assessment
This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian standards' requirements.
Resource implications for assessment include:
documentation that should normally be available in either a building or construction office
relevant codes, standards and regulations
office equipment, including calculators, photocopiers and telephone systems
computers with appropriate software to view 2-D CAD drawings, run costing programs and print copies
a technical reference library with current publications on measurement, design, building construction and manufacturers' product literature
a suitable work area appropriate to the construction process.
Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.
Method of assessment
Assessment methods must:
satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package
include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application
reinforce the integration of employability skills with workplace tasks and job roles
confirm that competency is verified and able to be transferred to other circumstances and environments.
Validity and sufficiency of evidence requires that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.
Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.
Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.
