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 by carrying out the necessary preparatory processes and developing at least two examples of each form of drawing specified, using sample or case study heritage projects for any of the buildings listed in the range statement.

This unit of competency can 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:

clearly understand conservation considerations and consultative processes associated with preservation of historic structures

clearly appreciate preservation of fabric

comply with OHS regulations applicable to workplace operations

apply organisational quality procedures and processes within the context of preparing drawings to conservation requirements

apply recording and identification system for measurements, locations and details

select and use appropriate processes, instruments and equipment to measure and record information

use appropriate and safe techniques to obtain measurements and details

apply accurate techniques in preparing information for related drawings

select and use appropriate techniques to ascertain accurate analysis of featured design shapes

apply techniques to ensure all relevant information is included in orthographic description

select and use appropriate techniques to produce accurate, sharp and complete drawings.

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:

historic locations appropriate to competency range

drafting and computer equipment

equipment relevant to measuring processes.

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

Required skills for this unit are:

ability to use instruments and equipment for measuring

communication skills to:

enable clear and direct communication, using questioning to identify and confirm requirements, share information, listen and understand

read and interpret:

documentation from a variety of sources

plans, specifications and drawings

use and interpret non-verbal communication

use language and concepts appropriate to cultural differences

written skills to record relevant information

numeracy skills to calculate measurements

organisational skills, including the ability to set out work

work to scale.

Required knowledge

Required knowledge for this unit is:

Australian standards - AS1100.101 and AS1100.301

conservation processes, including good conservation practice arising from principles of Burra Charter

methods of measuring

relevant architectural knowledge, including orders of architecture and the characteristics and features of period architecture

workplace and equipment safety requirements, including relevant statutory regulations, codes and standards.
