Application
This unit of competency specifies the outcomes required to carry out levelling in a single plane for the purpose of establishing correct and accurate set-out of building components. It includes the set-up, testing and use of levelling devices, and establishing and transferring heights using a range of levelling equipment.
The unit supports workers in the construction industry who use a variety of common methods and equipment when working with others and as a member of a team. It applies to levelling work on residential and commercial work sites.
No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

Evidence of Performance
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.
Evidence of Knowledge
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.
Assessment Conditions
Suitable assessment of performance requires:
equipment and tools:
as listed in the range of conditions and assessment requirements
specifications:
job requirements
health and safety requirements
manufacturer specifications
safety data sheets (SDS)
SWMS
workplace and relevant work site procedures
relationships with team members and supervisor:
work must be completed as part of a team and under direct supervision and observation
timeframe:
according to job requirements.
Assessor requirements
As a minimum, assessors must satisfy the assessor requirements in the Standards for Registered Training Organisations (RTOs) current at the time of assessment.
Foundation Skills
This section describes the language, literacy, numeracy and employment skills essential to performance in this unit but not explicit in the performance criteria. | |
Skill | Performance feature |
Numeracy skills to: | interpret and calculate levelling readings and measurements. |
Reading skills to: | read and interpret documentation from a variety of sources, including drawings and specifications. |
Writing skills to: | enter routine data associated with levelling procedures legibly into workplace documentation. |
Planning and organising skills to: | plan and schedule work in a logical sequence. |
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. |
