Elements and Performance Criteria

1. Plan for construction activities
   • Identify the construction site and the construction method
   • Take representative samples for soil tests
   • Locate services and utilities, check depths against the site plan and report discrepancies to the supervisor
   • Consider the site history when planning construction details
   • Determine likely consequences of site aspect, features and run-off from adjacent sites and incorporated in construction plans
   • Identify work health and safety hazards, assess risks, implement controls
   • Select, use and maintain suitable safety equipment and personal protective equipment (PPE)
2. Survey and lay out the construction site
   • Set up surveying equipment and establish and record existing levels and temporary benchmark
   • Set new levels and place pegs according to specifications
   • Determine the existing lay of the land and proposed contours
   • Shape new contours into the proposed site
3. Prepare for construction work
   • Obtain or develop plans for the new construction profile
   • Estimate and cost materials
   • Schedule work in a logical, timely and effective manner
4. Set out site for construction
   • Check and verify boundaries and features against the actual site and existing features
   • Check finishing levels, provision for drainage and irrigation to ensure nominated levels are workable
   • Check all measurements against the construction plan, peg out the construction area and account for variances
5. Excavate the construction site
   • Remove and stockpile excess soil in a designated area
   • Grade the base to the level and slope specified in the design
   • Consolidate the base of the profile to achieve uniform compaction over the entire site
   • Install sub-surface irrigation system components to the required depth and design specified in the plan
6. Install drainage system
   • Dig drainage trenches to the depth specified in the plan
   • Lay drainage material on the base of the trench, install pipes and cover trenches
7. Install soil profile
   • Calculate quantities of material to be spread over the area
   • Compact each profile layer to reflect the final contour
   • Ensure the interface between profile layers is uniform and unbroken
   • Mix soil amendments thoroughly and apply evenly over the area
   • Give the finished surface a final levelling and consolidate in readiness for planting
