Elements and Performance Criteria

1. Survey the construction site
   • Surveying equipment is set up and used according to industry standards.
   • Existing levels are surveyed and temporary benchmark established. Details are recorded accurately and legibly according to industry standards.
   • New levels are set according to specifications and pegs placed according to industry convention.
   • 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
   • Enterprise work team, contractors and design consultants are identified and, where required, engaged.
   • Work tasks are scheduled in a logical, timely and effective manner in consultation with the supervisor.
   • Materials required are estimated and costed according to accepted industry practice and ordered.
   • Plans for the new construction profile are obtained or developed.
3. Set out site for construction
   • Soil profile construction requiring set out.
4. Excavate the construction site
   • Excess soil is removed and the construction site cleared with the stockpile being placed in a designated area according to enterprise work procedures.
   • The base is graded to the level and slope specified in the base design.
   • The base of the profile is prepared over the entire site according to the construction plan.
   • Sub-surface irrigation system components and fittings are installed to the required depth and design specified in the construction plan.
   • Install drainage system.
5. Install soil profile
   • Quantities of material required are calculated and measured according to the construction plan.
   • Soils and growing media are selected for sustainable use and according to the construction plan.
   • Each profile layer is installed and compacted to reflect the final contour.
   • The interface between profile layers is uniform and unbroken according to the construction plan.
   • Soil amendments are prepared and implemented.
   • The finishing soil surface is given a final levelling and consolidated, ready for planting, according to the construction plan and enterprise work procedures.

Evidence Required

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 subsurface 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
