Required Skills
Required skills |
Required skills for this unit are: communication skills to: access information complete workplace documentation determine requirements enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand follow instructions plan and sequence tasks with others use language and concepts appropriate to cultural differences use and interpret non-verbal communication, such as hand signals identifying and accurately reporting to appropriate personnel any faults in tools, equipment or materials numeracy skills to apply measurements and calculations organisational skills, including the ability to plan and set out work removing water from a work site, which may be a trench, pit or well, using a pump teamwork skills to work with others to action tasks and relate to people from a range of cultural and ethnic backgrounds and with varying physical and mental abilities technological skills to: access and understand site-specific instructions in a variety of media use mobile communication technology. |
Required knowledge |
Required knowledge for this unit is: accessing information and the processes for calculating material requirements characteristics of stormwater installations, including capacity and installation procedures excavation processes and procedures job safety analysis (JSA) and safe work method statements (SWMS) levelling and alignment processes positioning and construction of sedimentation and scouring controls principles of drainage and installation processes process of draining a site properties of water, including pressure and flow rates relevant statutory and authority requirements related to draining work sites SI system of measurements standards applicable to the work workplace and equipment safety requirements. |
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 in the workplace or a close simulation of the workplace environment providing that simulated or project-based assessment techniques fully replicate plumbing and services 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: locating, interpreting and applying relevant information, standards and specifications to drain a work site applying safety requirements throughout the work sequence, including the use of personal protective clothing and equipment as a minimum the ability to, given the plans and specifications, drain water from a pit, trench or excavation containing water to a depth of at least half a metre, using a submersible pump; the site must remain effectively drained for the duration of the job, ensuring: correct identification of location, design and details of proposed installation correct selection and use of appropriate processes, tools and equipment completing all work to specification compliance with regulations, standards and organisational quality procedures and processes communicating and working effectively and safely with others. |
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: an induction procedure and requirement realistic tasks or simulated tasks covering the minimum task requirements relevant specifications and work instructions tools and equipment appropriate to applying safe work practices support materials appropriate to activity workplace instructions relating to safe working practices and addressing hazards and emergencies material safety data sheets research resources, including industry related systems information. 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. |
