Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

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

This unit of competency could be assessed in the workplace or a close simulation of the workplace environment, provided that simulated or project-based assessment techniques fully replicate construction workplace conditions, materials, activities, responsibilities and procedures.

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

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

locate, interpret and apply of relevant information, standards and specifications

comply with site safety plan and OHS legislation, regulations and codes of practice applicable to workplace operations

comply with organisational policies and procedures, including quality requirements

safely and effectively use tools and equipment

communicate and work effectively and safely with others

carry out a minimum of two stressbar post-tensioning cycles to specification, covering:

two different bar sizes

a minimum of thirty metres

standard tensioning

completion of site tensioning documentation.

Context of and specific resources for assessment

This competency is to be assessed using standard and authorised work practices, safety requirements and environmental constraints.

Assessment of essential underpinning knowledge will usually be conducted in an off-site context.

Assessment is to comply with relevant regulatory or Australian standards' requirements.

Resource implications for assessment include:

an induction procedure and requirement

realistic tasks or simulated tasks covering the mandatory task requirements

relevant specifications and work instructions

tools and equipment appropriate to applying safe work practices

support materials appropriate to activity

workplace instructions relating to safe work practices and addressing hazards and emergencies

material safety data sheets

research resources, including industry related systems information.

Reasonable adjustments for people with disabilities must be made to assessment processes where required. This could include access to modified equipment and other physical resources, and the provision of appropriate assessment support.

Method of assessment

Assessment methods must:

satisfy the endorsed Assessment Guidelines of the Construction, Plumbing and Services Training Package

include direct observation of tasks in real or simulated work conditions, with questioning to confirm the ability to consistently identify and correctly interpret the essential underpinning knowledge required for practical application

reinforce the integration of employability skills with workplace tasks and job roles

confirm that competency is verified and able to be transferred to other circumstances and environments.

Validity and sufficiency of evidence requires that:

competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace

where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice, with a decision on competency only taken at the point when the assessor has complete confidence in the person's demonstrated ability and applied knowledge

all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence.

Assessment processes and techniques should as far as is practical take into account the language, literacy and numeracy capacity of the candidate in relation to the competency being assessed.

Supplementary evidence of competency may be obtained from relevant authenticated documentation from third parties, such as existing supervisors, team leaders or specialist training staff.

Required Skills and Knowledge

Required skills

Required skills for this unit are:

communication skills to:

determine requirements

identifying and accurately reporting to appropriate personnel any faults in tools, equipment or materials

mathematical and numeracy skills to apply measurements and calculations

organisational skills, including the ability to plan and set out work

teamwork skills to work with others to action tasks and relate to people from a range of cultural and ethnic backgrounds and with varying physical and mental abilities

technological skills to:

use a range of mobile technology, such as two-way radio and mobile phones

voice and hand signals to access and understand site-specific instructions.

Required knowledge

Required knowledge for this unit is:

basic theory related to bar stressing as a reinforcement technology

calibration procedures related to stressing techniques and equipment

construction and steelfixing tensioning terminology

factors affecting concrete bonding, curing and strength

grouting equipment and procedures

quality requirements

requirements and processes for recording stressing operations

safe stressing procedures and stressbar techniques

workplace and equipment safety requirements.

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.

Information includes:

diagrams or sketches

manufacturer specifications and instructions, where specified

MSDS

memos

regulatory and legislative requirements pertaining to stressbar post-tensioning

relevant Australian standards

safe work procedures relating to stressbar post-tensioning

signage

verbal, written and graphical instructions

work bulletins

work schedules, plans and specifications.

Scope of work:

stressbar post-tensioning is designed to replace standard reinforcement materials with metal bars and, through tensioning, provide required strength in a reduced thickness of concrete

tensioning plans will contain position of bars, height of chairs, bar specifications, coupling arrangements for bars and stressing loads

stressbar sizes range from 16.0mm to 75.0mm

tensioning is stipulated in the job specifications but is not to exceed 85% of the ultimate tensile strength of the bar

types of structural elements include slabs, beams, columns, stay cable hangers, tension piles and caissons, stressed deck planks, ground anchors and soil nails

types of structures include buildings, bridges, towers, tanks, silos, stayed structures, offshore platforms, and underground and submerged structures

work is to conform to relevant Australian standard, unless this is replaced by superior specifications.

Safety (OHS) is to be in accordance with state and territory legislation and regulations and project safety plan and may include:

emergency procedures, including extinguishing fires, organisational first aid requirements and evacuation

handling activities that may require the assistance of others or the use of manual or mechanical lifting devices where size, weight or other issues, such as a disability are a factor

hazard control

hazardous materials and substances, including cement and curing agents

organisational first aid

PPE prescribed under legislation, regulations and workplace policies and practices
