RIINHB306E — Conduct large diameter auger drilling

1 Plan and prepare for large diameter auger drilling

• 1.1Access, interpret and apply conduct large diameter auger drilling documentation, and ensure the work activity is compliant
• 1.2Obtain, read, interpret, clarify and confirm work requirements
• 1.3Identify and address potential risks, hazards and environmental issues and implement control measures
• 1.4Select and wear personal protective equipment appropriate for work activities
• 1.5Communicate and coordinate activities with others throughout the work activity
• 1.6Obtain and interpret emergency procedures, and be prepared for fire/accident/emergency

2 Operate large diameter auger drill

• 2.1Carry out pre-start and start up procedures
• 2.2Identify, select and apply rig operational controls
• 2.3Collar borehole, start hole, maintain hole alignment, take corrective action for deflections
• 2.4Make up appropriate drill string
• 2.5Handle additional drill stems, inserting them in the drill string
• 2.6Use appropriate gears, rotation, feed and holdback so that flights or bucket are substantially full for the soil being drilled at any given depth
• 2.7Interpret drilling factors to determine conditions at the bit
• 2.8Make and break auger string and drive head connections
• 2.9Maintain a clear hole and a clear bottom and deploy tools for cleaning hole bottom at completed depth
• 2.10Interpret or calculate actual depth at any point during drilling, interpret depth of strata changes and identify fill depth in any bore
• 2.11Select appropriate strategies for recovery of dropped augers
• 2.12Recover drill string using winch and/or head/kelly
• 2.13Insert surface casing and deepen hole using smaller diameter auger or bucket, if required
• 2.14Disassemble drill string and change augers and bit components
• 2.15Select bits for formation being drilled
• 2.16Select appropriate augering method for situation
• 2.17Maintain spoil removal from hole collar
• 2.18Cover and secure bores
• 2.19Prepare and submit paperwork for daily activities
• 2.20Continually monitor hazards and risks, and ensure safety of self, other personnel, plant and equipment
• 2.21Select and use water and drilling fluids as appropriate
• 2.22Bell foundation piles, if required
• 2.23Clean pile bases and insert reinforcement cages, if required
• 2.24Deploy bucket augers through surface casing and when drilling under bentonite muds
• 2.25Use spin off and side casting of spoil as appropriate
• 2.26Record daily hole depths and progress

3 Respond to problems

• 3.1Identify possible operational problems in equipment or process
• 3.2Identify symptoms of problems needing remedial action
• 3.3Determine possible fault causes
• 3.4Rectify problem using appropriate solution within area of responsibility
• 3.5Follow through items initiated until final resolution has occurred
• 3.6Report problems outside area of responsibility to designated person

4 Complete equipment maintenance and housekeeping

• 4.1Carry out shutdown and secure equipment
• 4.2Monitor external wear in drill string, rotate string elements to ensure even wear
• 4.3Interchange drill bits and/or drill bit elements to maintain free cutting ability
• 4.4Check all string and equipment elements for wear and proper function
• 4.5Replace worn elements in string, bits and equipment and recycle ‘out of specification’ equipment for repair or redundancy
• 4.6Apply lubrication as appropriate
• 4.7Ensure housekeeping activities are completed
• 4.8Process records

What does an assessment tool for RIINHB306E need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for RIINHB306E needs to address all 75 unit components: 4 elements with 46 performance criteria, 16 performance evidence requirements, 13 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for RIINHB306E?

Auditori pulls the current release of RIINHB306E from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for RIINHB306E — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing RIINHB306E assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of RIINHB306E, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
