hand and power tools and equipment

bedding and backfill materials and handling methods

scale drawings for laying irrigation and/or 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

environmental impacts and procedures for laying pipe.

The range statement relates to the unit of competency as a whole.

Irrigation and drainage pipes may include:

concrete

metal

polythene

polyvinylchloride (PVC)

the type and size of pipe will vary with the terrain, soil type and traffic load.
