Elements and Performance Criteria

1. Determine shop and field connections from design drawings
   • Fabrication shop capabilities and preferences are discussed with fabricator
   • Connections are allocated as shop or field welded in conjunction with fabricator
   • Connections to be field bolted are allocated and extent of shop preparation of connections decided
   • Connection fittings are allocated to either columns or beams to suit fabrication efficiency or design requirements
   • A request for further information (RFI) is made to design engineer where clarification of requirements is needed
2. Detail bolts for connections
   • Knowledge of standard bolting category identification system is demonstrated
   • Bolt types and sizes for each connection are specified using design information and consideration of commercial availability
   • Bolt and thread lengths are selected according to design specifications, and connection requirements
   • Bolt and bolt holes are detailed taking into account AS 4100 requirements, tightening and tensioning specifications and clearances
   • Field bolt list is prepared and checked and sent to fabricator
3. Detail welds for connections
   • Knowledge of joint and weld types is demonstrated
   • Shop and field welds are identified
   • Standard welding symbols are used
   • Clearances for welding are applied
   • Field weld details are placed on erection plans and shop drawings and submitted to design engineer for approval

Required Skills

Required skills

assess design information for adequacy of information needed for structural steel detailing liaise with design engineers assess scope of structural steel detailing tasks and priorities interpret design drawings sketches and schedules determine bolt and thread length taking into account shank lengths as defined in AS and AS whether the thread is to be included or excluded in the shear plane grip and ply thicknesses thread projection as per AS nut and washer requirements detail welds consistent with design information and AS and AS Part 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 structural steel members and connections used in structural steelwork 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 Australian standard bolting category identification system bolt and thread length considerations including shank lengths as defined in AS and AS inclusion or exclusion of the shear plane in the thread grip and ply thicknesses thread projection requirements as per AS nut and washer requirements standard welding symbols as described in AS Part welding theory and processes

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 for assessment and evidence required to demonstrate competency in this unit	Demonstrates skills and knowledge to identify and interpret engineering design specifications for structural steel bolted and welded connections relate design information to structural steel detailing processes correctly use the Australian standard bolting category identification system understand and apply the relevant sections of AS Part AS AS and AS
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 ancillary structural steelwork including provision of suitable design information for bolts and welds 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
Bolt and thread lengths	Bolt and thread lengths may be specified by the engineer or by the detailer
Standard welding symbols	Standard welding symbols as described in AS 1101 Part 3
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.
