This unit describes a participant’s skills and knowledge required to conduct stabiliser operations in Civil Construction.

This unit is appropriate for those working in operational roles.

Licensing, legislative, regulatory and certification requirements that apply to this unit can vary between states, territories, and Industry sectors. Relevant information must be sourced prior to application of the unit.

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

locates and applies applicable documentation, policies and procedures

implements the requirements, procedures and techniques for the safe, effective and efficient completion of stabiliser operations including:

accessing, interpreting and applying documentation relevant to conducting stabiliser operations

identifying and applying relevant specifications to all work activities

identifying, addressing and reporting potential hazards and risks

identifying, obtaining, confirming and implementing signage requirements

selecting and checking for faults all plant, tools and equipment to carry out tasks

works effectively with others to undertake and complete stabiliser operations in a way that meets all requirements including:

preparing for and organising work activities to meet all task requirements

communicating clearly and concisely with others to receive and clarify work instructions

using a range of communication techniques and aids to advise others of work activity and exclusion zones

monitoring movements and hazards and identifying and communicating changes to the work environment during the work process

demonstrates completion of conducting stabiliser operations that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

conducting stabiliser pre-operational checks and rectifying or reporting any faults

operating stabiliser correctly and safely

relocating stabiliser safely

carrying out operator maintenance and keeping records

clearing work area and disposing of, recycling or storing materials

cleaning, checking, maintaining and storing plant, tools and equipment

the conduct of stabiliser operations performed on two (2) separate projects and to include:

churning up (excavating and remixing) existing fill

refilling in layers using the stabilised material

mixing materials

applying additives

achieving specified line and depth

enhancing the properties of the existing pavement

decreasing permeability

volume change

stabilising of an area to be performed utilising two (2) different additive types for at least five-hundred square metres (500m2) ensuring moisture content, additive application rate, pulverising, mixing, line and length are in accordance with project specifications

The candidate must demonstrate knowledge in conducting stabiliser operations through:

accessing, interpreting and applying organisation and site requirements and procedures for conducting stabiliser operations for:

identifying and managing risks

identifying, addressing and reporting environmental issues

setting up work activity

site isolation, signage, erecting barriers and traffic control

work health and safety

managing waste

selecting and checking for faults, tools and equipment to carry out tasks

carrying out work to specifications

manufacturer’s design specifications

applying effective techniques for stabiliser operations

An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,

this unit must be assessed in the context of this sector’s work environment; and,

this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,

assessment may be conducted in conjunction with the assessment of other Units of Competency; and,

assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,

assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,

where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,

assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level

Foundation skills essential to performance are explicit in the performance criteria of this unit. Further information is available in the Resources and Infrastructure Industry Training Package Companion Volume.
