Rebar Shop Drawings: A Guide to Reinforcement Detailing for Australian Projects

By the SolidCAD drafting team, Dandenong VIC · Published 22/10/2026

Reinforcement is hidden once the concrete is poured, which is exactly why getting it right on paper matters. Rebar shop drawings and schedules tell the steel supplier what to cut and bend, and tell the fixers where every bar goes. This guide covers what they include, how they are prepared and what causes problems on site.

What are rebar shop drawings?

Rebar shop drawings, also called reinforcement detailing drawings or placing drawings, are prepared from the structural engineer's drawings. The engineer's drawings show the design requirements, such as bar sizes, spacings and covers. The shop drawings turn those requirements into an exact, buildable layout, with every bar marked, sized and scheduled for supply.

What a good rebar package includes

• Placing drawings: plans and sections showing the location, spacing and layers of reinforcement in slabs, beams, columns, walls and footings.
• Bar marks: a unique mark for each bar shape and size, linking the drawing to the schedule.
• Bending schedules: bar mark, size, shape code, dimensions, quantity and total mass, so the supplier can cut and bend accurately.
• Laps, cogs and development lengths as required by the structural drawings and the concrete standard (AS 3600).
• Cover and chair requirements, so fixers know how to support the bars at the right depth.
• Openings, penetrations and set-downs, with trimmer bars where the engineer requires them.
• Pour breaks and staging, so each pour can be ordered and fixed separately.

How rebar shop drawings are prepared

The detailer starts from the approved structural drawings and specification, cross-checked against the architectural drawings for set-downs, openings and edges. Bars are laid out, marked and scheduled, usually in AutoCAD, Revit or Tekla depending on the project and the supplier's needs. The package is issued for review by the builder and engineer, comments are closed out, and the final issue goes to the supplier and site.

Australian reinforcing bar notation, such as N12 or N16 for normal-ductility deformed bars and SL meshes for fabric, should match the engineer's notation and the supplier's ordering system. Consistency between drawings and schedules is essential.

Common problems and how to avoid them

Congestion at joints

Beam-column joints and wall intersections can become so congested that bars cannot physically fit or concrete cannot flow. Good detailing checks these zones in section and resolves conflicts before supply.

Clashes with services and embeds

Penetrations, cast-in plates, conduits and anchor bolts all compete for space. Coordinating the rebar layout with services and embedded items avoids cutting bars on site, which often needs engineer approval.

Schedule and drawing mismatches

If a bar mark on the drawing does not match the schedule, the wrong bars arrive on site. A checked, model-based or schedule-linked workflow reduces this risk.

Working from superseded drawings

Structural revisions are common during design. Always detail from the current issue and record the revision you worked from on every drawing.

Who prepares and approves rebar shop drawings?

They are usually prepared by the reinforcement supplier, the builder or a drafting firm working for them. The builder reviews them, and they are often submitted to the structural engineer to confirm they follow the design. Design responsibility stays with the engineer.

What to send for a rebar detailing quote

• The current structural drawings and general notes, with the revision clearly shown.
• Architectural drawings for set-downs, openings, edges and finishes.
• The pour sequence or staging plan, if known.
• Your supplier's preferred schedule format and bar shape codes.
• The programme, including the first pour date.

With that information the drawing list, pour-by-pour issue dates and quotation can be confirmed quickly, so supply can be ordered in time for each pour.

Frequently asked questions

What are rebar shop drawings?

Rebar shop drawings are reinforcement placing drawings and bending schedules prepared from the structural engineer's drawings. They show the exact location, size, shape and quantity of every bar so it can be supplied and fixed correctly.

What is included in a rebar bending schedule?

A bending schedule lists each bar mark with its size, shape code, bending dimensions, quantity and mass, so the supplier can cut and bend the reinforcement accurately.

Who prepares rebar shop drawings?

They are usually prepared by the reinforcement supplier, the builder or a drafting firm working for them, and then reviewed by the builder and often the structural engineer.

Which software is used for reinforcement detailing?

AutoCAD, Revit and Tekla are all used for reinforcement detailing. The best choice depends on the project, the design model and what the supplier and site team need.
