Unit Descriptor

Unit descriptor 

This unit covers the process of installing aggregate paths and defines the standard required to: set out the path on a site; undertake ground preparation for an aggregate path; construct the aggregate path and supporting structures; minimise the impact of the aggregate path on the surrounding natural area; dispose of waste materials according to requirements.

Application of the Unit

Application of the unit 

This unit applies to the process of installing aggregate paths in landscape projects. The standard relates to working under direct supervision with regular checking. It requires the application of knowledge in Occupational Health and Safety (OHS) responsibilities, setting out, reading of plans, use of different aggregate materials, tools and equipment used in installation of paths and methods of disposing of soil and waste materials in order to minimise damage to the environment.
