Application
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.
Prerequisites

Evidence Required
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. |
