Modification History

Release	Comment
1	This unit replaces RIINHB305A Conduct continuous flight auger drilling
2	Required frequency and volume of evidence amended in Performance evidence. Substantial amendments made in Assessment Conditions field, including: references to Industry Sectors, assessor and subject matter expert experience requirements, how assessment should be conducted and what it should confirm.

Performance Evidence

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 relevant documentation, policies and procedures

implements the requirements, procedures and techniques for the safe, effective and efficient completion of continuous flight auger drilling including:

identifying and reporting all potential hazards, risks and environmental issues

interpreting geological maps, bore logs, diagrams, plans and instructions used for recording and prediction

applying grout mixing techniques and placement methods

applying water levels recording requirements

works effectively with others to undertake and complete the continuous flight auger drilling tasks that meets all of the required outcomes including:

complying with written and verbal reporting requirements and procedures

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

communicating clearly and concisely with others to resolve coordination requirements prior to commencing and during work activities

demonstrates completion of the conduction of continuous flight auger drilling that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

collaring borehole, starting hole, maintaining hole alignment, and taking corrective action for deflections

making up appropriate drill string

handling additional augers, inserting them in the drill string

applying rotation, feed and holdback so that flights are substantially full for the soil being drilled at any given depth

interpreting flow from the flights and other factors to determine conditions at the bit

describing and logging/recording, description of the soils being excavated

selecting appropriate strategies for recovery of dropped augers

recovering drill string using winch and/or head/kelly and disassemble drill string

abandoning, covering/securing bores to ensure safety of others and crew

Knowledge Evidence

The candidate must demonstrate knowledge in conducting continuous flight auger drilling through:

accessing, interpreting and applying the organisation and site requirements and procedures for:

work, health and safety

environmental issues

operating drill rig

housekeeping

identifying equipment spares and characteristics

understanding equipment technical capabilities, system limitations, gauge readings and their interpretation

understanding soil sampling techniques, deployment methods and record keeping

complying with operational maintenance procedures for rig and equipment including pre-start checks

understanding the basic geological formations likely to be encountered and their properties

using water, mud and foam injection for jet auger drilling

being prepared for fire/accident/emergency

Assessment Conditions

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:

Industry sector	AQF** Level	Required assessor or Industry subject matter expert experience
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction	1	1 Year
2	2 Years
Drilling, Coal Mining and Extractive (Quarrying)	3-6	3 Years
Metalliferous Mining and Civil Construction	3-6	5 Years
Other sectors	Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

*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
