CPCPRF4011 - Design and size roof drainage systems

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:
*designing, sizing and documenting the layout of a roof drainage system including overflows for two varied roof types:
*one incorporating eaves gutter for a residential (Class 1) building, and
*one for a commercial (Class 6) building incorporating a box gutter and sumps or rain heads.

Students will also be expected to demonstrate the following knowledge:
*relevant information sources for designing and sizing roof drainage systems
*processes for calculating catchment areas and design flows
*quantity and size of gutters, sumps, rain heads and downpipes determined according to relevant Australian Standards, plans and specifications
*environmental requirements and sustainability principles including efficient design principles
*drawing instruments and sketching techniques, including the use of conventional symbols
*use of computers and computer-aided design (CAD) software for documentation
*how to access relevant information, including codes and standards
*tools, materials and equipment used to design, size and document the layout of roof drainage systems
*work health and safety (WHS) requirements for designing, sizing and documenting the layout of roof drainage systems.
