Elements and Performance Criteria

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
maps
material safety data sheets (MSDS)
memos
organisation's work specifications and requirements
plans and specifications
regulatory and legislative requirements
relevant Australian standards
safe work procedures or equivalent
signage
verbal or written and graphical instructions
work bulletins
work schedules.
Safety (OHS) is to be in accordance with state or territory legislation and regulations, organisational safety policies and procedures, and project safety plan and may include:
clothing and equipment
handling of materials
hazard control
hazardous materials and substances
organisational first aid
use of firefighting equipment
use of tools and equipment
workplace environment and safety.
Equipment includes:
calculators and laser equipment
rulers
tape measures
trundle wheels.
Measurements are to:
be in metric scale
cover all necessary calculations.
Areas and volumes include:
calculating regular and irregular shapes, such as rectangles, squares, circles, triangles, trapeziums, cubes, cones, pyramids and cylinders that represent calculations taken in a construction environment.
Calculation factors:
include length, area, weight, height, width, depth, volume, mass, scales, ratios, perimeters, quantities, numbers, grade, percentages, addition, subtraction, multiplication and division
are to be performed manually and with the aid of a calculator.
Material quantities are to be:
calculated in either packed, bulk, loose or compacted states
converted to volumes in the other states.

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 relevant information
comply with site safety plan, OHS regulations and state and territory legislation 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
complete measurements, calculations and determination of quantities for different projects of varying complexity in a range of contexts or occasions over time
calculate each of the following using a realistic construction task or example:
length
perimeter
circumference
area
volume
number
ratio
percentage
conversion of metres to millimetres and millimetres to metres
measure using a rule or tape measure five separate tasks within 1mm accuracy.
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.
