Elements and Performance Criteria

  1. Plan and prepare.
  2. Set up and use levelling device.

Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Health and safety requirements must include:

emergency procedures, including:

evacuation

first aid

hazard identification and risk control procedures

safe operating procedures for levelling, including:

manufacturer specifications

safe work method statements (SWMS)

safety data sheets (SDS)

selection, correct fitting, and use of personal protective equipment (PPE) prescribed under legislation, regulations and workplace policies and practices

selection and use of tools and equipment.

Levelling tools and equipment must include:

each of the following:

laser levels and targets

marking equipment

measuring tapes and rules

spirit levels and straight edges

two of the following:

automatic/optical levels

plumb bobs

water levels.

Levelling device tolerance checks must include one or more of the following:

reverse readings for spirit level

two peg test for automatic level.

Marks for heights or levels must include:

chalk or nail mark

mark on vertical surface

datum or survey peg

drawing or sketch.

Levelling activities must include three or more of the following:

measuring and recording heights for the installation of signage

positioning offsets and recovery pegs for construction projects

recording ground levels at respective critical set-out points

recording heights or level and the transfer of data points

recording or checking levels in drainage

recording slab or pad levels for placement of steel columns or masonry piers

setting up levelling devices

shooting levels for concrete slabs

transferring levels and heights for formwork.


Performance Evidence

A person who demonstrates competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. The person must also transfer levels and record differences in height for three different projects as required by job specifications, using at least three of the following levelling devices:

a spirit level and straight edge

automatic/optical levelling device

levelling with water technique

laser levelling device.

In doing the above work, the person must:

conduct a two peg test with an automatic/optical level to confirm that the instrument meets manufacturer tolerances

locate, interpret and apply relevant information in job specifications to the levelling task

comply with site safety plan, and health and safety regulations applicable to workplace operations

comply with organisational policies and procedures, including quality requirements

safely and effectively use tools and equipment

communicate and work effectively and safely with others, including using agreed communication signals

confirm accuracy of the readings taken, including set-up and movement of device in two locations

accurately record results of each levelling procedure according to organisational requirements.


Knowledge Evidence

A person demonstrating competency in this unit must demonstrate knowledge of:

characteristics, technical capabilities and limitations of different types of levelling devices

methods of performing calculations associated with levelling

processes for setting out levelling tasks

requirements for line, level and plumb in construction projects

site and equipment safety requirements relevant to basic levelling procedures

symbols and construction terminology used when interpreting construction plans

techniques used when applying basic levelling procedures

contents of and terms used in job safety analyses (JSA) and safe work method statements (SWMS) and the use of this documentation when levelling.
