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 codes AS requirements in so far as they impact on steel detailing

Evidence Required

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 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 members and their connections

relate design information to detailing of structural steel members

establish efficient administrative arrangements for liaison with designers

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 of appropriately simulated detailing of structural steel members 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 andor 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

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

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, written instructions or computer files

Direction marks

Direction marks are indicated on the shop drawings and on the beam or girder by the words 'North' or 'West' as applicable. Industry standard practice is to determine the placement of these marks by viewing and numbering the beams and girders from the bottom or right hand edge of the floor plan. Variations from this practice may occur on specific projects and should be noted on the erection plan

Beam dimensions

Beam dimensions are obtained from design information in conjunction with Design Capacity Tables (see below) and manufacturers' catalogues. Beam dimensions to be inserted into shop drawings should include:

longitudinal dimensions

centre to centre distance between supports

overall length of the beam

overall cut length of the beam

dimensions of holing and other details occurring along the length of the beam. The method of showing hole dimensions may be centre to centre, consecutively from end to end of beam or as running dimensions according to the needs of the fabricator

longitudinal dimensions to groups of holes in the web or flange

vertical dimensions to top most holes for end connection elements

Additional dimensions and symbols may be required for non-proprietary welded plate girders. These dimensions and symbols would be specified by the designer and would normally include web and flange dimensions, web stiffener locations and welding symbols

Working points

Working points for trusses may also be referred to as setting out points or intersection points

Design Capacity Tables

Design Capacity Tables refers to the publication 'Design Capacity Tables for Structural Steel, Volume 1: Open Sections' published by the Australian Steel Institute

Connections

All connections are steel to steel unless specifically noted

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

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.
