ASQA / RTO

The Certificate III in Steelfixing (CPC31120) is the nationally recognised Australian trade qualification for steelfixers — the workers who read drawings and bar schedules, cut and bend reinforcement, and tie bars and mesh to the correct spacing and cover for concrete structures. It is delivered by Registered Training Organisations and is competency-based: rather than one fixed exam, candidates are assessed Competent or Not Yet Competent across 17 units of competency (14 core plus 3 elective), combining knowledge evidence with practical and workplace tasks. Core trade theory follows AS 3600 (concrete structures) and AS/NZS 4671 (reinforcing steel), and covers bar designations (N/R bars), cover and exposure classifications, lap and development lengths, SL and trench mesh, post-tensioning basics, and dogging/rigging and WHS. A construction induction (White) card via CPCCWHS1001 is required to work on site. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1On Australian structural drawings, what does the bar designation 'N16' indicate?
A.A 16 mm round plain bar of normal ductility
B.A 16 mm deformed bar of 500 MPa grade and normal (Class N) ductility
C.A bar with 16 transverse ribs per metre
D.A 500 MPa bar that must be lapped 16 times its diameter
Explanation: Under AS/NZS 4671, 'N16' means a Deformed (D500N) bar of 16 mm nominal diameter, 500 MPa characteristic yield strength, and Normal (Class N) ductility. The 'N' replaced the older 'Y' notation used in Australia.
2A bar schedule lists a bar as '12N16-300'. How should a steelfixer interpret this callout?
A.12 bars of N16 spaced at 300 mm centres
B.N16 bars laid in a 12 m by 300 mm grid
C.12 mm bars, 16 of them, 300 mm long
D.Number 12 bar, type N, 16-300 mark
Explanation: A standard reinforcement callout in the form 'quantity / bar-mark / spacing' reads as 12 bars of N16 deformed bar placed at 300 mm centres. Reading these callouts correctly is fundamental to placing the right steel.
3On a reinforcement drawing, what does the abbreviation 'EF' next to a bar callout most commonly mean?
A.Each face
B.Extra fitment
C.End fixing
D.Equal flange
Explanation: 'EF' stands for 'each face' and tells the steelfixer that the specified bars are to be placed on both faces of the member (for example, in a wall or thick slab). 'NF' and 'FF' indicate near face and far face respectively.
4Which document gives the steelfixer the exact lengths, shapes and bending dimensions of every bar required for a job?
A.The bar bending schedule
B.The architectural floor plan
C.The safe work method statement
D.The concrete delivery docket
Explanation: The bar bending schedule (BBS) lists each bar mark with its diameter, shape code, cutting length and bending dimensions, and quantity. Steelfixers and bar-benders work directly from the BBS to cut and bend reinforcement.
5What does a 'shape code' on a bar bending schedule define?
A.The bending configuration and dimension points of a bar
B.The grade of steel in the bar
C.The supplier's delivery sequence
D.The colour coding used on site
Explanation: A shape code is a standardised reference (with associated dimension letters A, B, C, etc.) that defines how a bar is to be bent and where each bend point sits. The schedule pairs the shape code with the actual dimensions so the bar-bender forms the correct shape.
6On a slab plan, reinforcement shown as 'B' bars and 'T' bars refers to bars placed in which positions?
A.Bottom layer (B) and top layer (T)
B.Beam (B) and tie (T) reinforcement only
C.Both faces (B) and transverse (T)
D.Bracket (B) and trimmer (T) bars
Explanation: In slab detailing, 'B' denotes bottom reinforcement and 'T' denotes top reinforcement. Correctly identifying top from bottom steel is critical because their structural roles (sagging vs hogging) differ.
7A bar mark 'R10' on a fitment schedule indicates what type of bar?
A.A 10 mm plain round bar of 250 MPa grade
B.A 10 mm deformed bar of 500 MPa grade
C.A bar bent to a 10 mm internal radius
D.A ribbed bar with 10 mm cover
Explanation: The 'R' prefix designates a plain round bar of 250 MPa (R250N) grade, commonly used for fitments such as ligatures and stirrups in smaller members. The number is the nominal diameter in millimetres.
8When the bar schedule states a cutting length, what does it already account for?
A.The total developed length of the bar including allowances for bends
B.Only the straight portion before the first bend
C.The length of tie wire required
D.The lap length plus 25%
Explanation: The scheduled cutting length is the total developed length of the bar measured along its centreline, including the straight legs and the allowances built in for each bend. Cutting to this length ensures the finished bent shape fits the member.
9On a reinforcement plan the note 'SL92 mesh' appears for a slab. What does the '92' tell the steelfixer?
A.9 mm assigned main wire diameter and 200 mm aperture
B.92 mm spacing of the wires
C.9 sheets at 2 m widths
D.Grade 920 steel
Explanation: In square mesh designation 'SLxy', the first digit (9) is the assigned main wire diameter in millimetres and the second digit (2) denotes a 200 mm aperture (wire spacing). So SL92 has 8.6 mm-class main wires at 200 mm centres.
10Australian square reinforcing mesh such as SL72 and SL82 is manufactured to which standard?
A.AS/NZS 4671
B.AS 1554
C.AS/NZS 3500
D.AS 1657
Explanation: Reinforcing bar and mesh in Australia and New Zealand are manufactured to AS/NZS 4671 (Steel for the reinforcement of concrete). SL-series welded square mesh and N/R bars all conform to this standard.
