Description
This unit of competency specifies the skills and knowledge required to use technical instruments and levelling and surveying techniques to accurately set-out a building on site. It includes determining grid levels and developing contour plans. It applies to National Construction Code (NCC) classifications: Residential - Class 1 and 10 buildings, maximum two storeysCommercial - Class 2 to 9, Type C only constructions This unit of competency applies to builders, site supervisors and related construction industry professionals responsible for ensuring accurate application of site surveys and set-out of a residential and/or commercial building.This unit is suitable for those using specialised knowledge to complete routine and non-routine tasks and using their own judgement to deal with predictable and sometimes unpredictable problems.Completion of the general construction induction training program specified by the model Code of Practice for Construction Work is required for any person who is to carry out construction work. Achievement of CPCWHS1001 Prepare to work safely in the construction industry meets this requirement.Licensing, regulatory or registration requirements apply to this unit of competency in some jurisdictions. Relevant state and territory regulatory authorities should be consulted to confirm these requirements.
Notes
Elements and Performance Criteria
1 Prepare for and conduct site set-out.
  • 1.1 Source, read and follow current project plans and site set-out procedures.
  • 1.2 Select and use levelling devices in accordance with standard operating procedures (SOPs).
  • 1.3 Apply the ‘two peg test’ to check the amount of error present in the instrument.
  • 1.4 Carry out reduction in a closed level run by rise and fall method and by height of plane collimation (HPC) method.
  • 1.5 Calculate accurate staff readings to enable a specific reduced level (RL) set-out.
  • 1.6 Identify and explain errors in measured distances due to site characteristics and measurement methods.
2 Develop a contour grid.
  • 2.1 Determine set-out grid and levels.
  • 2.2 Prepare contour plans from grid levels to specified tolerances and stated contour intervals.
  • 2.3 Determine surface area being levelled and calculate cut and fill volumes.
  • 2.4 Calculate and record trigonometric and geometric calculations commonly used with grid lines, off sets and right-angle triangles without error.
3 Determine grades and levels.
  • 3.1 Draw longitudinal sections from RLs.
  • 3.2 Determine levels and clearances from given grades and distances to specified tolerances.
  • 3.3 Express calculation angles, percentages and run ratios in grades.
  • 3.4 Determine calculations for batter levels from grades and distances.
  • 3.5 Construct longitudinal sections and determine associated grades and levels in typical drainage and pipeline situations.
