Description
This unit of competency covers the production of structural precast and prestressed concrete products such as beams and girders. It involves preparing the mould and assembling the reinforcing, ensuring quality of concrete, monitoring the process and removing the work piece from the mould.
Notes
Elements and Performance Criteria
1. Prepare mould for casting
- 1.1. Check casting schedule and job specification
- 1.2. Clean and oil moulds according to requirements
- 1.3. Check for mould damage and repair as necessary
2. Assemble reinforcement cage
- 2.1. Lift preassembled reinforcing sections into mould using good occupational health and safety (OHS) practice
- 2.2. Assemble additional steel to complete cage to drawings and job specification
- 2.3. Fit additional items, such as base plates, tie plates and lifting devices, according to work instructions
- 2.4. Fit hold-ups and hold-downs as appropriate
- 2.5. Place voids or ducts according to work specifications
- 2.6. Run prestressing strands through reinforcing cages as required
- 2.7. Set up guards and comply with OHS requirements for stressing
- 2.8. Tension strands to extension dimensions and/or gauge readings according to works or engineer instructions
- 2.9. Recheck reinforcing cage is in correct position and adjust as necessary
3. Close mould and test vibrators
- 3.1. Lift mould sides and additional parts into position and secure to specification
- 3.2. Fit any additional items as required
- 3.3. Seal mould
- 3.4. Fit vibrators to start positions
- 3.5. Test run before casting commences
4. Pour concrete
- 4.1. Begin casting in accordance with work instructions
- 4.2. Move vibrators and time vibration as required
- 4.3. Screed top surface flat in preparation for final finish if required
- 4.4. Patch product as required
- 4.5. Clean mould and worksite in accordance with OHS requirements
5. Control concrete quality
- 5.1. Test raw materials as required
- 5.2. Prepare test cylinders and samples as required
- 5.3. Monitor and control concrete mix to keep within specifications
- 5.4. Update all records and file all records and supplier certificates in appropriate place
- 5.5. Raise non-conformance reports as required
6. Cure product
- 6.1. Cover and cure mould and test cylinders in accordance with standard procedures and work instructions
- 6.2. Monitor curing to achieve specified stripping strength
7. Strip and store product
- 7.1. Test samples to ensure specific strength has been achieved
- 7.2. Remove mould sides and store ready for cleaning
- 7.3. If applicable, de-stress in accordance with work procedures and sequences
- 7.4. Ensure unit is lifted according to work instructions and moved to store, supported only on points designated on the drawings
8. Respond to problems
- 8.1. Identify possible routine and non-routine problems in the equipment or process
- 8.2. Determine problems needing action
- 8.3. Determine possible fault causes
- 8.4. Rectify problem using appropriate solution within area of responsibility
- 8.5. Report problems outside area of responsibility to designated person
9. Control hazards
- 9.1. Identify hazards from the job to be done
- 9.2. Identify other hazards in the work area
- 9.3. Assess the risks arising from those hazards
- 9.4. Implement measures to control those risks in line with procedures
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Procedures
All operations are performed in accordance with standard procedures and work instructions
Typical problems
Typical problems may include:
slippage, breaking of tensioned strands
mould leakage
compaction in areas with high reinforcement content (end blocks and haunches)
compact product with tight bends/clearances
polystyrene blocks (which may be used in formwork to lighten products) may float to surface on vibration
polystyrene blocks may move sideways undetected, reducing wall thickness
adjustment to take account of variables such as weather
variations in cement/water ratio
OHS
All operations are subject to stringent OHS requirements and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and OHS requirements, the OHS requirements take precedence

EVIDENCE GUIDE
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that the process be understood and that the importance of critical material properties and design characteristics is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.
Consistent performance should be demonstrated. In particular look to see that:
products are made consistently in minimum time and with minimum patching
finishing is within specification/example
good OHS practice is used consistently.
Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.
Context of and specific resources for assessment
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations.
Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.
Simulation or case studies/scenarios may be required to allow for timely assessment of parts of this unit of competency. Simulation should be based on the actual plant and will include 'walk-throughs' of the relevant competency components. A bank of scenarios/case studies/what ifs and questions will be required to probe the reasoning behind observable actions.
Method of assessment
Individual enterprises may choose to add prerequisites and co-requisites relevant to their processes.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
