Evidence Required

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 research design analysis evaluation and reporting to determine service layout and connection methods for large and complex residential and commercial buildings

Competency must be demonstrated within the context of relevant legislation the BCA and Australian standards

This unit of competency can be assessed in the workplace or a close simulation of the workplace environment provided that simulated or projectbased 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

coordinate and assess input received from technical experts

comply with OHS regulations applicable to workplace operations

apply organisational management policies and procedures including quality assurance requirements where applicable

evaluate the services layout connection methods and rectification actions for at least one residential and one commercial building project or equivalent which includes advice on hot and cold water supply sewerage layout electrical and electronic installation lighting systems vertical transportation requirements and smoke and fire detection and prevention systems

provide reports to appropriate body or individual as determined by project brief

apply strategic plans workplace policies and procedures

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 offsite context

Assessment is to comply with relevant regulatory or Australian standards requirements

Resource implications for assessment include

a situation real or realistically simulated requiring assessment of service layout and connection method requirements for residential and commercial buildings

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 persons 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
