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 construction of monitoring bore that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

confirming scope of work with client and gaining agreement on drilling plan

assembling and inserting casing and screens

placing artificial pack material in a manner so as to ensure uniform distribution in the annular space without bridging

labelling and securing the well

completing a construction diagram showing all details of the construction

using a range of development techniques to improve hydraulic transmissivity around the bore

carrying out decommissioning of test holes per geological formation and hydrological setting


Evidence of Knowledge

The candidate must demonstrate knowledge in constructing monitoring bores through:

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

work, health and safety

environmental issues

operating drill rig

housekeeping

basic geological formations, i.e. various formations which permit groundwater movement and factors affecting groundwater quality

characteristics of ‘good samples’ required for water well construction

ways in which sampling errors can occur

the types of muds, their use, and development techniques to remove them from bores

grout placement methods and procedures

water sampling techniques and protocols

the monitoring systems and alarms requirements and procedures

the ground preparation requirements and procedures

the inspection, fault finding and reporting requirements and procedures

diagrams, plans and instructions for positioning, recording work or progressbeing 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
