Assist in the construction of wet gap crossings

This unit covers the competency required to assist in the preparation, construction, operation and recovery of wet gap crossing bridging equipment, including:floating support bridgesfixed floating span equipmentferry equipment (captive and free)floating support bridgeraftsimprovised floating structuresto cross rivers and other wet gaps to facilitate the movement of personnel, vehicles, cargo and equipment.Wet gap crossing is defined as a bridge that is physically supported by the water, i.e. through pontoons and associated buoyancy measures. Bridges will normally be constructed on a temporary basis 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.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

This competency was developed for combat engineer personnel required to assist in the preparation, construction, operation and recovery of wet gap crossing bridging equipment, including floating support bridges, to cross rivers and other wet gaps 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 individual will usually be engaged in bridge construction as part of a team under supervision, but may undertake some autonomous tasks.

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

Prerequisites

Not applicable.

Elements and Performance Criteria

1. Construct wet gap crossing equipment

1.1 Appropriate personal protective equipment is selected and worn in accordance with WHS requirements.

1.2 Site layout and preparation is conducted in accordance with standard procedures.

1.3 All wet gap crossing bridging components are checked against the inventory and materials list for completeness and are prepared for operation with faults and deficiencies reported to the supervisor.

1.4 Tools and equipment required for the task are selected, checked for serviceability and faults are reported to the supervisor.

2. Construct wet gap crossing equipment

2.1 Jigs, fixtures and equipment to be used in construction are assembled and adjusted ready for use.

2.2 Bridge components are assembled and checked for compliance, accuracy and alignment in accordance with standard procedures.

2.3 Equipment is operated in accordance with standard procedures.

3. Maintain and clean up site and equipment

3.1 Gap crossing sites and crossing systems are maintained in accordance with standard procedures.

3.2 Gap crossing equipment, tools and unused materials are recovered, cleaned, maintained and documentation is completed, with any faults and deficiencies reported in accordance with standard procedures.

3.3 Gap crossing equipment, tools and materials are either stored or redeployed to another site in accordance with standard procedures.

Evidence Required

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

Assessment must confirm the ability to assist in the construction of at least two wet gap crossings using two types of wet gap crossing bridging equipment listed in the Range Statement. Individuals should be assessed participating in the construction of:

one gap crossing with a span of at least 30 metres

one crossing at night.

Assessment must also confirm the ability to:

prepare a crossing site

check components, tools and equipment for serviceability and completeness

participate in the assembly, construction operation and recovery of various types of crossing systems

communicate effectively and work as part of a team.

Consistency in performance

Competency should be demonstrated under field conditions over a time frame that allows for individuals to be assessed in the various tasks related to the construction of at least two wet gap crossings using two types of equipment listed in the Range Statement.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace or in a simulated workplace environment.

Specific resources for assessment

Access to:

wet gap crossing equipment and components (fixed floating span equipment; ferry equipment; floating support bridge; rafts; improvised floating structure)

tools, plant, equipment and materials required to support the operation of wet gap crossing equipment including the construction of supporting devices such as aerial ropeways

wet gap area for training area

transport, small watercraft, plant and operators.
