Qualification -
Unit of Competency PUADEFDV014B - Perform concreting in an underwater environment
Description This unit covers the competency required to concrete simple forms and excavations in an underwater environment.The unit also includes preparing the underwater site for concreting including any necessary excavation and levelling, constructing simple formwork and positioning reinforcement rods and fixed anchorages.The diver will need to prepare the concrete with consideration given to strength and setting periods. The concrete will need to be poured and screeded to the required finish.The diver will be responsible for the recovery of formwork and waste arising from the work task to ensure the preservation of the environment. Finally, the concreting tools must be de serviced and stored appropriately for ongoing use.Note: This Unit of Competency relates, in part, to the existing standards of the Australian Diver Accreditation Scheme (ADAS). All information was correct at the time of development of this Unit of Competency; however, any diver seeking ADAS accreditation should consult ADAS and not rely on the information contained in this unit.
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/sPUADEFDV001B Dive using self contained underwater breathing apparatus in open water to 30 metres

Elements of Competency Performance Criteria              
Element: Prepare for underwater concreting
  • Work task and worksite data are determined and analysed to determine the specific requirements for the concrete
  • Work plan is developed consistent with the dive plan
  • Concretingequipment is selected, inspected and prepared including protective equipment
  • Concreting equipment is secured safely to/from the dive site
  • Access obstructions and other hazards are assessed and action is taken to remove/reduce the risk
       
Element: Concrete underwater site
  • Work-safe area is established at the worksite
  • Site is cleared and levelled in preparation for the pour
  • Formwork is assembled including stripping agents
  • Reinforcing bars, rods, stirrups and mesh, bar chairs and spacers are positioned
  • Cement is mixed in accordance with the setting and strength specifications
  • Location and safety of divers is confirmed prior to commencing the pour
  • Cement is delivered to the site with a consistent flow
  • Concrete is spread to the required levels incorporating expansion joints
  • Concrete is screeded to a level and the surface is finished using floats or brooms
  • Concrete is protected during curing
       
Element: Conclude underwater concreting
  • Environmental impact arising from the concreting is minimised and waste products and formwork are recovered
  • Concreting and protective equipment are de-serviced and stored after use
       


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 attend to personal and collective safety; and to consider the environmental impact as part of the dive plan.

Consistency in performance

Competency should be demonstrated during a work task where the diver conducts an underwater concreting task such as the reinforcement of pier legs, the placement of footings or laying of a slab or ramp.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the ocean.

When practicable, assessment should relate to the diver’s vocational focus.

Specific resources for assessment

Access to a dive location, a complete range of concrete ingredients and concreting equipment.

Guidance information for assessment

Information that will assist or guide assessment will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

Submission Requirements

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.
