Unit Descriptor

This unit covers the competency required to construct, and recover gap crossing bridging equipment, to facilitate the movement of personnel, vehicles, cargo and equipment.

Bridges will normally be constructed on a temporary basis under field conditions to meet the operational need to provide a crossing point over a gap for personnel and equipment. When the crossing is no longer required the bridge is either recovered to storage or redeployed to another crossing.

Equipment bridging is constructed from designed and certified bridge modules and parts to provide a temporary or permanent bridge over a gap.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. In a Defence context, this means that there is no civilian need to hold this unit in order to meet licensing, legislative, regulatory or certification requirements.

Application of the Unit

This competency was developed for combat engineer personnel required to construct, and recover gap crossing bridging equipment, to facilitate the movement of personnel, vehicles, cargo and equipment in a deployed operational environment but is applicable to any individual in this field of work.

The person will usually be engaged in bridge construction by leading a team and working autonomously.

All activities are carried out in accordance with relevant organisational policies and procedures.

Licensing/Regulatory Information

Not applicable.

Pre-Requisites

Evidence Guide

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

Assessment must confirm the ability to lead a team to construct, maintain and dismantle a multi span bridging of not less than 30 metres made from modularised or improvised means.

Consistency in performance 

Competency should be demonstrated over time and across a range of simulated or actual workplace situations that allows for the construction of multi-span bridging under a range of field conditions.

Context of and specific resources for assessment 

Context of assessment 

Competency should be assessed in the workplace or in a simulated work environment. Assessment need only be completed once due to the high cost and complex nature of the task.

Specific resources for assessment 

Access to construction equipment and materials; communications equipment; a suitable site; and a construction team.
