What evidence is required to demonstrate competence for this standard as a whole

Competence in laying irrigation andor drainage pipes requires evidence that a person can set out and excavate trenches check trench depth and grade lay bedding materials and position pipes to job specifications and supervisor instructions The skills and knowledge required to lay pipes must be transferable to a different work environment For example this could include different pipes types and sizes soil types and enterprises

What specific knowledge is needed to achieve the performance criteria

Knowledge and understanding are essential to apply this standard in the workplace to transfer the skills to other contexts and to deal with unplanned events The knowledge requirements for this competency standard are listed below

workplace and equipment safety requirements for excavating filling trenches and laying pipes including relevant legislation regulations and codes

irrigation andor drainage pipes types and sizes

hand and power tools and equipment

bedding and backfill materials and handling methods

scale drawings for laying irrigation andor drainage pipes

hand signals for communication

OHS issues and procedures related to trenching and pipe laying

Quality Assurance procedures for excavating filling trenches and laying pipes

What specific skills are needed to achieve the performance criteria

To achieve the performance criteria appropriate literacy and numeracy levels as well as some complementary skills are required These include the ability to

read and interpret scale drawings and specifications

use hand signals for communicating with machine operator

measure trench width depth grade and location

level cover with existing ground

use power tools and hand tools

handle materials safely

work safely to instructions

What processes should be applied to this competency standard

There are a number of processes that are learnt throughout work and life which are required in all jobs They are fundamental processes and generally transferable to other work functions Some of these are covered by the key competencies although others may be added The questions below highlight how these processes are applied in this competency standard Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where not required perform the process perform and administer the process and perform administer and design the process
