using a calculator to calculate hole volume
works effectively with others to undertake and complete the conduct of guided bores 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 guided bores that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:
fitting and locating device to drill head and attaching drill head to drill stem
aligning drill head with survey tool and survey control system
drilling pilot hole according to design alignment
monitoring drill path ensuring pilot hole meets conformance envelope and dogleg severity is within limits
steering, and where required, zone steering drill head to achieve required pitch and direction
monitoring and interpreting all gauge/dial readings
monitoring and interpreting drill head position and pitch
completing back reaming, and product pull back

Assessment Conditions
Assessors must satisfy the Standards for Registered Training Organisations (RTOs) 2015/AQTF mandatory competency requirements for assessors; 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.
