Assist in the construction of wet gap crossings

Assessment tool

Version 1.0
Issue Date: March 2024


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.

This unit covers the competency required to assist in the preparation, construction, operation and recovery of wet gapcrossing bridging equipment, including floating support bridges, to 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 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. The individual will usually be engaged in bridge construction as part of a team under supervision, but may undertake some autonomous tasks.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 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 by observing the individual assisting in the assembly, construction, and maintenance of various types of wet gap crossing equipment that may include floating support bridges, ferries, rafts and fixed floating span equipment in accordance with standard procedures and instructions, by day and night and should cover all of the Critical aspects of evidence.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level, required for this unit.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
