Range of VariablesThe Range of Variables explains the range of contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment may depend on the work contexts |
What retaining wall projects are covered by this unit? | Retaining wall projects include all modular concrete, timber, brick, dry stone and mortared block. |
What resource requirements are likely to be identified? | Resource requirements may include base materials, sub-surface drainage materials, retaining wall components, levelling equipment and powered tools, and other equipment associated with construction. |
What might be the environmental implications of proposed work site activities? | Environmental implications may include risk of contamination of soils, water, or adjoining property through fuels flowing into drains and water sources, or changes to drainage patterns. Compliance with local, State/Territory, and Commonwealth environmental legislation is required. |
What OHS hazards may apply to work site activities? | Hazards may include disturbance of services, solar radiation, dust, noise, through traffic, uneven surfaces and holes, moving machinery and machinery parts, powered equipment and hand tools, hazards from use of hired equipment (untrained staff), and overhead hazards including powerlines. |
What PPE is likely to be selected? | PPE will be determined by the type of activity being undertaken and may include work boots, gloves, overalls, sun hat, sunscreen lotion, and hearing or eye protection. |
What services are likely to be located on site? | Services may include power, gas, water, stormwater, sewerage or septic connections, phone and optical cables. |
What drainage systems are likely to be installed? | Drainage systems may include sumps, agricultural drains, storm water pipes and slotted pipes. |
