Description
This unit covers the process of constructing stone structures and features as a component of landscape project works and defines the standard required to: interpret plans and specifications; prepare the site and install drainage systems; construct stone work with correct mortar ratio; set out base for paving.
Notes
Elements and Performance Criteria
1. Plan and prepare work
  • 1.1. Plans and specifications are interpreted and clarified with the supervisor.
  • 1.2. The quantity and quality of materials are checked to ensure they conform to design drawings and specifications.
  • 1.3. Tools and equipment are selected and checked for serviceability according to enterprise guidelines.
  • 1.4. Occupational Health and Safety (OHS) hazards are identified, risks assessed and controls implemented.
  • 1.5. Environmental implications of erecting stone structures are identified and reported to the supervisor.
2. Set out and prepare the site
  • 2.1. Services are determined and located from site plans.
  • 2.2. The position of the structure or feature is marked out according to design drawings and specifications.
  • 2.3. Profiles are established to conform to the tolerances nominated within the design drawings and specifications.
  • 2.4. Subsoil is prepared by removing all debris, vegetable matter and topsoil to provide a solid foundation for construction.
  • 2.5. Drainage systems are installed according to design drawings and specifications.
  • 2.6. Sub-base material is placed and compacted to the required finished levels.
3. Construct structure or feature
  • 3.1. Mortar is mixed to determined ratio and appropriate admixes including bonding and colouring agents are added as required, and in accordance with specifications.
  • 3.2. Damp proofing and base course of stone work is laid according to design drawings and specifications.
  • 3.3. Courses of stone work are laid using designated bond/s in a manner that will ensure the viability and stability of the structure, and according to design drawings and specifications.
4. Install stone paving
  • 4.1. Set out and prepare area to be paved according to the site plan.
  • 4.2. The area is excavated to shape, depth and dimensions to sub base level according to industry standards.
  • 4.3. The sub base is trimmed to the designated level and falls, and base material is placed and compacted to the required finished level.
  • 4.4. Bedding material is spread over the area and levelled to the designated level and falls.
  • 4.5. Stone is placed and fitted to accurately fill gaps in the pattern within tolerances nominated within the site plan.
  • 4.6. Edge constraints are installed as required by the site plan.
5. Check quality of work and clean up site
  • 5.1. Quality of finished works is inspected to ensure the standard of the finished structure or feature is in accordance with design drawings and specifications.
  • 5.2. Stone work surfaces are cleaned down in an environmentally safe and sensitive manner.
  • 5.3. Tools and equipment are cleaned and stored according to enterprise guidelines.
