Issue Date: April 2024


Qualification -
Unit of Competency DEFCA308B - Assist in the construction and maintenance of field structures
Description This unit covers the competency required to construct and maintain a range of field structures, such as bunkers, strongpoints, towers and shelters.Construction is usually of a temporary nature and is undertaken employing expedient construction methods using both commercially available and improvised materials. The individual will usually work as part of a team under supervision, but may undertake some autonomous tasks. Construction will normally be carried out in a field environment.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package.This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites Prerequisite Unit/sBCG1004A Carry out measurements and calculationsBCG1006A Use small plant and equipmentBCG1008A Use simple levelling devicesBCG1009A Carry out excavation and install supportBCG1010A Carry out concreti

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.

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

Assessment must confirm the ability to construct at least three types of field structures included in the Range Statement using a variety of materials and expedient construction methods. At least one above and one below ground structure should be constructed.

Assessment must also confirm the ability to:

interpret job instructions and plans, and layout a site

prepare materials and equipment for construction

apply appropriate expedient construction methods and procedures to the construction including accurate measuring and levelling

use standard processes to handle and place materials

complete the construction of field structures to the specified standard

work in a team and interactively communicate with others

Consistency in performance

Competency should be demonstrated under field conditions over a time frame that allows for constructing and maintaining a number of field structures utilising expedient construction methods and a variety of materials.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in a field environment. Evidence should be gathered by observing the individual participating in the construction of various types of field structures requiring the application of a variety of expedient methods and materials.

Specific resources for assessment

Access to:

construction materials relevant to the task

hand tools, power tools, plant and other equipment appropriate to the construction process

suitable training areas for construction.

Submission Requirements
