Description
This unit covers the process of constructing soil profiles and defines the standard required to: determine construction requirements from plans; survey and create working plans for construction sites; excavate earthworks and establish working and finished levels; install drainage and sub-surface irrigation components; install sustainable soils and growing media; implement a construction project.
Notes
Elements and Performance Criteria
1. Survey the construction site
  • 1.1. Surveying equipment is set up and used according to industry standards.
  • 1.2. Existing levels are surveyed and temporary benchmark established. Details are recorded accurately and legibly according to industry standards.
  • 1.3. New levels are set according to specifications and pegs placed according to industry convention.
  • 1.4. Contour map with reduced levels and a cross section is developed and drawn using accepted industry symbols and mapping conventions.
2. Prepare for construction work
  • 2.1. Enterprise work team, contractors and design consultants are identified and, where required, engaged.
  • 2.2. Work tasks are scheduled in a logical, timely and effective manner in consultation with the supervisor.
  • 2.3. Materials required are estimated and costed according to accepted industry practice and ordered.
  • 2.4. Plans for the new construction profile are obtained or developed.
3. Set out site for construction
  • 3.1. Soil profile construction requiring set out.
4. Excavate the construction site
  • 4.1. Excess soil is removed and the construction site cleared with the stockpile being placed in a designated area according to enterprise work procedures.
  • 4.2. The base is graded to the level and slope specified in the base design.
  • 4.3. The base of the profile is prepared over the entire site according to the construction plan.
  • 4.4. Sub-surface irrigation system components and fittings are installed to the required depth and design specified in the construction plan.
  • 4.5. Install drainage system.
5. Install soil profile
  • 5.1. Quantities of material required are calculated and measured according to the construction plan.
  • 5.2. Soils and growing media are selected for sustainable use and according to the construction plan.
  • 5.3. Each profile layer is installed and compacted to reflect the final contour.
  • 5.4. The interface between profile layers is uniform and unbroken according to the construction plan.
  • 5.5. Soil amendments are prepared and implemented.
  • 5.6. The finishing soil surface is given a final levelling and consolidated, ready for planting, according to the construction plan and enterprise work procedures.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole.
Constructing profiles may include:
construction sites
landscaping sites
land developments
farms
land management operations
restoration projects.

This standard does not cover high performance turf sporting surface constructions.
EVIDENCE GUIDE
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:
determine construction requirements from plans
survey and create working plans for construction sites
excavate earthworks and establish working and finished levels
install drainage and sub-surface irrigation components
install sustainable soils and growing media
implement a construction project.
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.
