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 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:
locate, interpret and apply relevant information, standards and specifications
comply with site safety plan and OHS legislation, regulations and codes of practice applicable to workplace operations
comply with organisational policies and procedures including quality requirements
safely and effectively operate and use tools, plant and equipment
communicate and work effectively and safely with others
as a minimum:
repair a crack in a concrete basement wall or a suspended car park slab, identifying remedial waterproofing method to be used, determining the type of material to be used and the repair requirement (e.g. spacing of injection ports/packers if using an injection method), and testing the application
inject a chemical damp course into a solid 230 brick wall/party wall and a cavity brick wall, plugging each procedure with epoxy plug, ensuring:
correct identification of requirement and installation of the waterproofing
correct selection and use of appropriate processes, tools and equipment
completing all work to specification.
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:
workplace location or simulated workplace
materials relevant to remedial waterproofing processes
hand and power tools, plant and equipment appropriate to remedial waterproofing processes
realistic activities covering the mandatory task requirements
specifications and work instructions.
Assessment of this unit of competency may be in conjunction with assessment of other units commonly performed at the same time in normal job roles.
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.
