MSL973009
Conduct field-based acceptance tests for construction materials


Application

This unit of competency covers the ability to conduct in situ tests to confirm the acceptability of raw or manufactured, construction materials prior to or after their use. Personnel are expected to be able to work independently and liaise with site personnel to ensure that testing is conducted safely and efficiently. They may transport samples and/or equipment to and from the site, as necessary, and prepare test pieces on-site for later laboratory testing.

This unit of competency is applicable to laboratory personnel working in the geotechnical and construction material testing industry sectors who conduct relatively quick and straightforward control and compliance tests using established test methods. These tests could involve aggregates, concrete, soils, road pavement or other specialised construction materials.

The unit could also be relevant to laboratory technicians working in the water/wastewater and trade waste industry sectors.

While no specific licensing or certification requirements apply to this unit at the time of publication, laboratory operations are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked.

Assessment Conditions

Judgement of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event.

This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills.

Foundation skills are integral to competent performance of the unit and should not be assessed separately.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case).

This unit of competency may be assessed with:

MSL922001 Record and present data

MSL943001 Work safely with instruments that emit ionising radiation

MSL943002 Participate in laboratory or field workplace safety

Holistic assessment methods include:

review of test data, results and records generated by the candidate

feedback from supervisors and clients regarding the candidate's ability to work independently and conduct a range of field-based acceptance tests reliably, safely and efficiently

oral/written questions about workplace procedures and test methods relevant to their job role.

Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:

sampling and test equipment and materials specified in the test method

test methods and description of test set-up, data sets and records

calculator and/or computer and relevant software or laboratory information system.

Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.

The assessor must demonstrate both technical competence and currency.

Technical competence can be demonstrated through:

relevant VET or other qualification/Statement of Attainment AND/OR

relevant workplace experience.

Currency can be demonstrated through:

performing the competency being assessed as part of current employment OR

having consulted with a laboratory about performing the competency being assessed within the last twelve months.
