Qualification -
Unit of Competency MSL973009A - Conduct field-based acceptance tests for construction materials
Description 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.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application 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 at extractive, manufacturing or construction sites 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/waste water and trade waste industry sectors.Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These can be found at the end of this unit of competency under the section 'This competency in practice'.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

liaise effectively with site personnel to arrange for testing to be performed safely and efficiently

conduct field-based acceptance tests and collect/prepare associated field samples or test pieces safely and accurately and within the required timeframe.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with other relevant units of competency such as:

MSL922001A Record and present data

MSL943001A Work safely with instruments that emit ionising radiation

MSL943002A Participate in laboratory/field workplace safety.

Resources may include:

data sets and records

test methods and description of test setup

computer and relevant software or laboratory information system

relevant enterprise procedures.

Method of assessment

The following assessment methods are suggested:

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

questions to assess understanding of enterprise procedures and test methods relevant to their job role.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Construction materials testing

A technician working for a consulting laboratory receives a telephone request from a client to conduct some concrete tests at their site at 10 am. They require a slump test and the preparation of three test cylinders and two flexural beam test pieces for later testing. The technician arrives at the site early and checks with the foreman about where the concrete truck will come in and positions his/her vehicle in a shady spot close by where the samples can cure without being disturbed. He/she prepares the slump plate, shovel, scoops, slump rod, cylinder moulds, bucket, steel ruler, spirit level, thermometer, brushes and worksheets. He/she checks the slump plate for level and damps down the moulds when the truck arrives. After waiting for the recommended volume of concrete to be discharged, he/she collects a sample and conducts the slump test. He/she pays particular attention to how each layer is added to the cone and 'rodded' and then carefully lifts off the cone in one easy motion. Using the slump rod on top of the cone as a benchmark, he/she measures the slump as 80+/-5 mm. This result is consistent with the results obtained from several repeat tests. He/she returns the slump material to the kibble and collects five buckets of concrete to make the cylinders and beams.The technician places a maximum/minimum thermometer alongside the prepared samples to monitor the curing process and the covers them with insulating material. He/she carefully cleans all the test equipment while the concrete is still wet and re-stows it in thevehicle. On returning to the laboratory, he/she ensures that all results and records are competed according to standard procedures.

Construction materials testing

A laboratory technician has been tasked with conducting a series of field density measurements using a nuclear gauge at a road construction site. Prior to leaving for the site, he/she locates the test method (AS 1289.5.8.1) and assembles all the materials and equipment needed for the job. The technician reviews the company's safe working rules for using the gauge, conducts the specified pre-use checks of the equipment, does a 'standard count' and enters all the required information in the relevant technical and administrative records. After safely stowing the equipment, he/she drives to the site. On arrival, the technician checks with the foreman about the size of the lot, test locations and datum point and the details about the other work currently going on at the site. The technician sets up the specified safety barriers and signs, ensures that the gauge is operating correctly and checks the radiation levels around the instrument. He/she drills the first of the ten required holes, carefully ensuring that it is the correct depth and is vertical, clear of obstructions and large enough to enable the gauge to be raised and lowered without jamming. He/she spreads sand near the hole to ensure that the instrument is flush with the ground and there is no air gap. With the source in position, he/she performs two measurements (@ 0º and 90º) to minimise the effect of any rocks or voids that may be close to the surface. He/she notes that the two results agree to within the accepted tolerance of 75kg/m3. The technician then carefully retracts the rod and locks the source in its shielded position before moving the instrument to the next location. After successfully completing all the required measurements, the technician carefully cleans, checks and re-stows the equipment, fills in the holes, removes the barriers/signs and advises the foreman that he/she has finished the testing. On returning to base, he/she finalises the job in accordance with enterprise procedures.
