Elements and Performance Criteria

  1. Prepare for field-based acceptance tests
  2. Perform field tests
  3. Collect site samples and prepare test pieces
  4. Finalise field testing
  5. Maintain a safe work environment

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Standards, codes, procedures and/or workplace requirements

Standards, codes, procedures and/or workplace requirements include the latest version of one or more of:

Australian and international standards covering the requirements for the competence of testing and calibration laboratories, laboratory safety and quality management

national work health and safety (WHS) standards and codes of practice, national measurement regulations and guidelines, and environmental legislation and regulations

standard methods for testing construction materials, such as soils, aggregates, concrete and asphalt

specific codes, guidelines, procedures and methods, such as:

AustRoads test methods, State/Territory Road Authority test methods

National Association of Testing Authorities (NATA) documents regarding construction materials testing (Field application document)

workplace documents, such as standard operating procedures (SOPs); quality and equipment manuals; calibration and maintenance schedules; material safety data sheets (MSDS) and safety procedures; material, production and product specifications; production and laboratory schedules; workplace recording and reporting procedures; waste minimisation and safe disposal procedures; and maps, site plans and site safety plans

sampling and testing procedures for specific sites, clients and samples

Field-based acceptance tests

Field-based acceptance tests include, but are not limited to, one or more of:

testing of concrete, such as:

consistency (e.g. slump)

making and curing of concrete cylinders

air content

Schmidt hammer

testing of soils, such as:

field density (e.g. compaction control)

coarse particle distribution (e.g. rock protection layers and embankments)

dynamic cone penetration (DCP)

Clegg hammer

sample cores from stabilised pavements

testing of asphalt and bitumen seals, such as:

temperature of freshly laid asphalt

field density

texture depth

permeability

aggregate spread rate and binder spray rate

Appropriate corrective actions

Appropriate corrective actions include one or more of:

carefully re-reading of procedures and checklists

logically checking equipment set-up

checking calibration, zero error and drift for the measuring instrument

repeating test measurements

checking data entry and transcription for errors

seeking advice

Site samples and test pieces

Site samples and test pieces include, but are not limited to, one or more of:

site samples of aggregates, soil, concrete and road pavement

beams and cylinders for subsequent laboratory testing, such as Brazil test and Marshall stability/flow test

asphalt cores and slabs for testing wheel tracking and fatigue

Workplace safety procedures

Workplace safety procedures include, but are not limited to, one or more of:

recognising and observing hazard warnings and safety signs/barriers

labelling of samples, reagents and hazardous materials

use of PPE, such as hard hats, hearing protection, gloves, safety glasses, coveralls, respirators and safety boots

handling and storing hazardous material and equipment in accordance with labels, MSDS, manufacturer instructions, and workplace procedures and regulations

following established safe handling procedures for tasks involving manual handling

cleaning and decontaminating equipment and work areas regularly using recommended procedures

WHS and environmental management requirements

WHS and environmental management requirements include:

· complying with WHS and environmental management requirements at all times, which may be imposed through state/territory or federal legislation. These requirements must not be compromised at any time

· applying standard precautions relating to the potentially hazardous nature of samples


Performance Evidence

Evidence of competence in this unit must satisfy all of the requirements of the elements and performance criteria, and include demonstration of:

liaising with site personnel to ensure that sampling and testing is conducted safely and efficiently

conducting at least three (3) different in situ tests to confirm the acceptability of raw or manufactured construction materials prior to or after their use

collecting field samples and preparing test pieces safely and accurately within the required timeframe on at least two (2) occasions

recognising obvious errors or atypical data and taking appropriate corrective actions

maintaining security, integrity and traceability of field samples, test pieces, test data, results and documentation

cleaning, checking, safely transporting and storing test and sampling equipment

following workplace procedures for safe work and minimising environmental impacts.


Knowledge Evidence

Must provide evidence that demonstrates knowledge of:

the purpose and principles of construction materials tests performed as part of job role and key preparation/measurement steps in the test method

the properties of construction materials under test

calculation steps to give results in appropriate units and precision

expected values for sample type and sources of uncertainty (and methods for control) in construction materials tests routinely used in job role

pre-use checks and operating procedures for test equipment

procedures for recording and reporting test results, calculations, site observations, and handling unexpected or atypical results and equipment problems

procedures for ensuring traceability of samples, test pieces, test data and results

workplace confidentiality requirements relevant to job role

relevant hazards, work health and safety (WHS) and environmental management requirements.
