This unit applies to the process of designing for the construction of landscape features.

ELEMENT

PERFORMANCE CRITERIA

1. Interpret detail architectural and landscape design drawings

1.1. Detail architectural and landscape design drawings are interpreted for construction features.

1.2. Survey levels are defined and any site gradients recorded.

1.3. A small scale model is constructed from detail drawings.

1.4. Detail plans are drawn from pre-constructed landscape features, including cross-sections.

1.5. Drainage plans for a green site and a developed site are drawn to construction standards.

2. Design aspects of construction for landscape features in a range of materials

2.1. A concept design is developed for the construction of the selected landscape feature.

2.2. Aspects of construction for landscape features are illustrated.

2.3. A range of materials used in the construction of landscape features are utilised into the design.

2.4. Appropriate plants are selected for incorporation into the design.

3. Specify dimensions, footings and qualities of materials

3.1. The difference in quality of available materials is determined and quality criterion specified in the design.

3.2. Dimensions, footings and qualities of materials selected are identified and specified.

3.3. The consequences and costs involved in using poor quality materials are determined.

3.4. The construction standards are specified in the design.

4. Develop the required project management skills

4.1. A site strategy is developed for the design project.

4.2. Timelines for the project are identified and documented.

4.3. Project costs are determined and recorded.

4.4. Contractors on site are consulted and issues resolved.

4.5. A final design and project report are developed and documented.

Required skills

identify and specify dimensions, footings and quantities of materials

interpret detail architectural and landscape design drawings

interpret surveying and drainage plans

design components of construction

identify and document project timelines

calculate project costs

liaise with contractors

select appropriate materials and plants

use literacy skills to fulfil job roles as required by the organisation. The level of skill may range from reading and understanding documentation to completion of written reports

use oral communication skills/language competence to fulfil the job role as specified by the organisation, including questioning, active listening, asking for clarification, negotiating solutions and responding to a range of views

use numeracy skills to estimate, calculate and record complex workplace measures

use interpersonal skills to work with others and relate to people from a range of cultural, social and religious backgrounds and with a range of physical and mental abilities.

Required knowledge

construction standards

site services

principles of surveying

selection of appropriate plants and materials

drainage issues

available resources to resolve drainage problems

paving process

stone walling, including gabions

materials available in the marketplace

drainage issues and available resources to resolve drainage problems

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following:

interpret detail architectural and landscape design drawings

construct a small scale model

specify dimensions, footings and qualities of materials

develop a concept design for the construction

draw plans to construction standards

develop a final design and project report.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

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

Landscape designs may include:

a wide range of contexts and styles of presentation

design elements

styles

design plans and models.

Graphics may include:

a wide range of manual and electronic drafting techniques

computer-assisted drawings (CAD).

Constructions may include:

all landscape construction works.

Sites may include:

all areas of project works.

Landscape features may include:

all constructions, installations and structures.
