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

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

Demonstrates skills and knowledge to:

identify and interpret architect and engineer design specifications for structural steel constructions including design information for steel to steel and steel to non-steel connections

relate design information to structural steel detailing processes for connections

establish efficient administrative arrangements for liaison with designers including arrangements for formal requests for further information

establish drawing and document control procedures

identify standard components and connections from industry publications, manufacturers' catalogues and Australian or other relevant standards

Context of and specific resources for assessment

Assessment may occur on the job or in an appropriately simulated environment

Resource implications for this unit include:

access to real or appropriately simulated detailing of structural steel connections including provision of suitable design information

computer with suitable CAD software or manual drafting equipment and material including work areas, materials and equipment

access to steel and component manufacturers' catalogues or websites

access to relevant standards through either hard copy or internet access.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Manufacturing Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency where structural steel detailing is involved

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Required Skills and Knowledge

Required skills

assess design information for adequacy of information needed for structural steel detailing

liaise with architects and engineers

assess scope of structural steel detailing tasks and priorities

interpret design drawings, sketches and schedules, to determine dimensions, layouts, types and grades of materials

interpret manufacturers catalogues and product information

use basic trigonometry to determine dimensions not given in design information

work according to OHS practices of the enterprise and workplace which may include requirements prescribed by legislation, awards, agreements and conditions of employment, standard operating procedures, or oral, written or visual instructions

communicate at all levels about technical issues related to patterns and specifications

reading and numeracy is required to the level of interpreting workplace documents and technical information

Required knowledge

architectural and engineering design drawings including standard symbols, terms, abbreviations and sketches

connections used in structural steel construction

the difference between design and detail drawing processes

drawing office procedures

fabrication processes and procedures

the Australian steel structures limit state design code's (AS4100) requirements in so far as they impact on steel detailing

characteristics of portal frame construction especially the behaviour of the frame under load and points of high stress

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.

Legislative/regulatory requirements

All work must comply with relevant Federal and State or Territory legislative or regulatory requirements

Connections

All connections are steel to steel unless specifically noted

Design information

Design information is the information provided to the detailer and fabricator by the architects and consulting engineers for a project. For some projects the design information may only be provided by an engineer. The design information will usually be in the form of design drawings or sketches but may also be via material lists and written instructions and computer files

Standard connections

Standard connections are those specified in the Australian Steel Institute's publication 'Standardised Structural Connections'

Connection type

Connections may be standard flexible or rigid connections

Flexible connections may include:

angle seats

bearing pads

flexible end plates

angle cleats

web side plates

Rigid connections may include:

fully welded end plates

bolted moment end plates

Standard detailing parameters

Standard detailing parameters are connections suitable to be detailed using the standard bolting and welding specifications contained in the Australian Steel Institute's publication 'Standardised Structural Connections'. These details include:

size of fillet welds

electrode and MIG welding wire specification

bolt type and size

arrangement of holes for bolts

back gauge dimensions and minimum edge distances

distance from beam top to the first row of bolts

detailing parameters for components such as cleat plates, gussets, end plates, base plates and angle plates

Components

Components may include cleat plates, gussets, end plates, base plates and angle plates

Standard welding symbols

Standard welding symbols as described in AS 1101 Part 3

Non-steel connections

Non-steel connections are those between steel members and concrete, timber, glass or plastic or other building or fabricated component required to be shown on a structural steel detail drawing. The connection may be for structural or decorative purposes. An example would be steel supports for a timber deck

Haunch specifications

Haunches are special connections used in portal frame buildings. Haunch specifications supplied by designers will normally include:

roof slope

details of haunch location and size sufficient to ensure design requirements

end plate specification

bolting information

location and sizes of welds

fly bracing requirements

Fixings

Fixings may include standard bolts, dynabolts, chemsets, female internal thread tube bolts, and other specialist steel to non-steel fixings

Work environment

Detailing may be undertaken in a variety of work environments including commercial, home office or fabrication or construction enterprise.

Work may be performed individually on a contracting/project basis or as part of a project team and in response to combinations of paper based and electronic instructions.
