It includes planning and preparation for the work, laying and fixing anchorages and cables, defining the work area, stressing tendons, finishing the tensioning and completing clean-up activities.

Application of the unit

This unit supports the attainment of skills and knowledge to tension monostrand posts for a construction project, which includes working with others and as a member of a team.

Prerequisite units

CPCCOHS2001A

Apply OHS requirements, policies and procedures in the construction industry

Employability skills

This unit contains employability skills.

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

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 the full monostrand post-tensioning cycle to specification, covering:

five strand tendon

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.

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

instructions issued by authorised organisational or external personnel

manufacturer specifications and instructions, where specified

MSDS

memos

regulatory and legislative requirements pertaining to monostrand post-tensioning

relevant Australian standards

safe work procedures relating to monostrand post-tensioning

signage

verbal, written and graphical instructions

work bulletins

work schedules, plans and specifications.

Scope of work:

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

post-tensioning plans will contain position of cables, height of chairs, cable specifications, number of strands per cable and the stressing loads

monostrand is a single cable with a standard seven wire strand with sizes ranging from 12.7mm to 15.2mm

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

types of structural elements include slabs, beams, columns and ground anchors

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

safe operating procedures, including the conduct of operational risk assessment and treatments associated with:

cutting and grinding equipment

lighting

power equipment

power leads and sources

trip hazards
