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.
Building types include:
bridge and pier construction
buildings with concrete skeleton and slabs
concrete column or wall 10 metres high
slab on ground floor.
Records maintained include details regarding:
causes of surface defects during concrete placement
compaction of concrete
finishing processes and surface treatments to slab concrete.
Types of curing methods include:
accelerated curing
continuously wetting concrete
impermeable membrane curing.
Reinforced concrete includes:
methods of pre-stressed concrete
principles of reinforced concrete using steel, wire, fibres, etc.
Performance requirements include:
characteristics, uses, maintenance and selection of materials and systems in terms of their:

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 applying correct processes for selecting and sizing materials for all structural components that form a complex building project.
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:
comply with OHS and organisational quality procedures and processes
apply and interpret relevant documentation and codes
apply design principles relating to performance
identify typical faults and problems and the action required to rectify such faults.
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, including design brief drawings, specifications, codes, design concepts, construction schedules and other necessary supporting documents
research resources, including timber product information and samples
access to relevant legislation, regulations and codes of practice, including BCA, National Timber Framing Code and AS1684, AS4055
relevant computer software package and suitable hardware.
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.
