Notes
Elements and Performance Criteria
1 Plan and prepare for drawing requirements.
- 1.1 Specifications for drawing is identified from request or conservation authority requirements.
- 1.2 The dimensions of the historical or significant building are determined in accordance with appropriate methods, taking into account the type of structure, access to details and previous drawings available, if applicable.
- 1.3 The method of recording feature details is determined in accordance with the nature of the feature, location and accessibility.
- 1.4 The method and system of recording identification, location and dimensional information is determined and applied in accordance with requested drawing requirements.
- 1.5 Equipment and instruments required are identified, listed and used in accordance with recording task requirements.
2 Organise information for drawing preparation.
- 2.1 Information is gathered and organised to determine the overall dimensions of the building, structure or details to be drafted.
- 2.2 Information is gathered to identify and group all recorded details associated with each area or section of the building or structure.
- 2.3 The size of the drawing and scale to be used is determined in accordance with the dimensions of the building, structure or section.
- 2.4 Sketches, tracings or photographs of recorded features are identified and located with other recorded information related to feature work .
3 Draw or develop orthographic description.
- 3.1 Block layout of views and designed spacings, where applicable, are drawn or developed to planned layout and scaled accurately to recorded or calculated dimensions.
- 3.2 Orthographic description views are detailed to show visible lines of structure and elements as seen with each view to correct scale representation of recorded dimensions.
- 3.3 Architectural drawing conventions, symbols and hatching, where applicable, are shown on drawings in accordance with AS1100.301 - 1985 Architectural Drafting.
- 3.4 Plans of large buildings are produced by use of grids, where applicable, to provide cross referencing and dimensioning by coordinates.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, the range statement and the Assessment Guidelines for this 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 in this competency standard using sample or case study heritage projects for buildings listed within the range statement.
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:
clear understanding of conservation considerations and consultative processes associated with preservation of historic structures
clear appreciation of preservation of fabric
compliance with OHS regulations applicable to workplace operations
ability to apply organisational quality procedures and processes within the context of preparing drawings to conservation requirements
ability to apply sound recording and identification system for measurements, locations and details
ability to select and use appropriate processes, instruments and equipment to measure and record information
ability to use appropriate and safe techniques to obtain measurements and details
sound and accurate techniques in preparing information for related drawings
ability to select and use appropriate techniques to ascertain accurate analysis of featured design shapes
sound techniques to ensure all relevant information is included in orthographic description
ability to select and use appropriate techniques to produce accurate, sharp and complete drawings.
Context of and specific resources for assessment
Resource implications for assessment include:
historic locations appropriate to competency range
drafting and/or computer equipment
equipment relevant to measuring processes.
Where applicable, physical resources should include equipment modified for people with disabilities.
Access must be provided to appropriate learning and/or assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the oracy, language and literacy capacity of the work being performed.
Validity and sufficiency of evidence requires that:
competency must 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 of competence taken only at the point when the assessor has complete confidence in the person's competence
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit.
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the oracy, language and literacy levels of the operator, and to any cultural issues that may affect responses to the questions, and reflect the requirements of the competency and the work being performed.
