Unit guide for CPCPDR4002A Plan, size and lay out stormwater drainage systems

This unit of competency specifies the outcomes required to plan, size and document the layout of surface and sub-soil stormwater drainage systems. It covers preparation for the planning, identification and confirmation of system specifications and requirements, and the planning of the system layout and work finalisation processes, including records and documentation.

To meet the industry requirements for this unit learners will be expected to be able to:

  • Identify building sites and site features from location drawings
  • Identify typical faults and problems and take necessary remedial action
  • Apply creative design and drafting skills to meet site conditions and ensure compliance

Planning and organising

To meet the industry requirements for this unit learners will be expected to be able to:

  • Gather required tools and equipment
  • Ensure a coordinated development of drawings
  • Scope extent of work required
  • Plan details of relevant systems and layouts
  • Plan and arrange inspections
  • Ensure current building codes and standards are applied

  • Manage work priorities and professional development

Learning

To meet the industry requirements for this unit learners will be expected to be able to:

  • Use appropriate mechanisms to inform others of applicable standards and codes

Technology

To meet the industry requirements for this unit learners will be expected to be able to:

  • Use information technology skills to operate office equipment and computers including digital cameras
  • Use computer aided drafting (CAD) software where applicable to produce and manage architectural drawing and template files
  • Check relevant tools and equipment for serviceability

Purpose of activities

Activity – Rainfall intensity (data entry activity)

This activity is in Plan. After being given the Bureau of Meteorology rainfall intensity data for Newcastle, learners are asked to calculate the rainfall intensity in mm/h for the activity site.

Activity – Site inspection (matching activity)

This activity is in Plan. Learners are required to identify the purpose of various common site inspection tasks.

Activity – Stormwater sizing (interactive tutorial requiring data entry)

This activity is in Size. It is a combined audio tutorial and interactive calculation activity. Learners listen to the tutorial that details the steps to follow when sizing stormwater drainage pipework sections for a job site. Each stage of the tutorial commences with a worked example and then learners are required to complete calculations and fill in sections of the pipe sizing table. This is a complex activity. Please allow an adequate amount of time for learners to complete.

Communication activities

Teachers may ask learners to calculate the rainfall intensity for a variety of areas including their own town and then discuss the effect this data has on planning stormwater drainage systems. Learners are encouraged to contact the Environmental Protection Authority in their state to obtain the stormwater protection requirements. They may also like to take photos on site that demonstrate the way in which they manage their stormwater protection responsibilities and post these to a blog or wiki for discussion. Learners may also be required to contact their local council to obtain the council requirements for stormwater systems.

Assessment suggestions

Assessment for this unit is very specific as noted in critical aspects for assessment and evidence for the unit. Teachers may choose to use the Toolbox On the job task as the basis of a workplace assessment or the final RTO based assessment task for this unit. RTOs are responsible for developing the assessment criteria that underpins the assessment of this unit.

Teachers may choose to use the On the job task as the basis of a skill recognition pathway for learners with existing skills and knowledge in this unit. Learners should be encouraged to review the On the job task and consider this pathway option.
