Reinforcing Bar Placement & Tying SWMS
Reinforcing bar placement and tying for in-situ concrete — horizontal and vertical starter bars, mesh sheets, bar chairs, and bundle handling with spreader bars.

Reinforcing bar placement and tying is a foundational steel-fixing activity on virtually every in-situ concrete project, from residential slabs to high-rise core walls and infrastructure pours. The work involves manually positioning horizontal and vertical starter bars, laying mesh sheets, installing bar chairs, and rigging bundled reo with spreader bars — exposing workers to impalement, crush, manual-handling, and laceration risks across the full shift. Under WHS Regulation 2025, this scope is classified as High Risk Construction Work (HRCW) because it routinely involves a risk of a person falling onto exposed projecting reinforcement and because bundle lifts engage powered mobile plant near workers. A Safe Work Method Statement is therefore mandatory before work commences, must be developed in consultation with the workers carrying out the task, and must be reviewed whenever the control measures, sequence, or site conditions change. This SWMS documents the hazards, hierarchy-controlled measures, sign-on register, and supervisor verification process required to lawfully place and tie reinforcement on Australian construction sites.
Hazards identified
7 hazards covered, sorted by priority.
Penetrating abdominal or thoracic trauma, internal organ damage, potential fatality, and prosecutable s19 PCBU duty breach
Fractured limbs, crush syndrome, traumatic amputation, and fatality where bundle exceeds 500 kg lift weight
Chronic lumbar disc injury, wrist tendinopathy, and long-term workers compensation claims under Manual Tasks CoP
Deep hand and forearm lacerations, tetanus exposure, infection requiring surgical debridement and time off work
Sprains, fractures and secondary impalement risk if the worker falls onto adjacent vertical starters
Corneal abrasion, foreign body penetration, and permanent vision loss without compliant impact eye protection
Heat exhaustion, heat stroke, collapse, and elevated injury rates from impaired judgement late in shift
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where design permits, substitute in-situ tied reinforcement with prefabricated reo cages delivered to site, eliminating manual placement and tying at height entirely.
- 2Elimination — Sequence concrete pours so vertical starter bars are encased within 48 hours, removing prolonged impalement exposure on the working deck.
- 3Substitution — Replace hand-tied connections with proprietary mechanical couplers or pre-welded mesh modules to reduce repetitive wrist motion and tie-wire laceration exposure.
- 4Substitution — Use plastic-tipped or mushroom-capped reo safety caps rated to AS/NZS 4671 impact criteria in place of bent-over bar ends.
- 5Engineering — Fit certified impalement protection caps or timber capping rails on every vertical starter bar exceeding 200 mm projection before workers access the area.
- 6Engineering — Use certified spreader bars and tagged lifting chains for all bundle lifts, with exclusion zones marked by hard barricades and spotter communication via two-way radio.
- 7Administrative — Rotate steel fixers between tying, cutting and placing tasks every 90 minutes and schedule reo handling outside peak heat hours per Manual Tasks CoP 2011.
- 8Administrative — Conduct documented pre-start briefings against this SWMS, verify HRCW sign-on register, and re-brief whenever bar diameter, lift weight or weather conditions change materially.
- 9PPE — Issue cut-level D gloves, long-sleeve hi-vis, steel-midsole boots to AS/NZS 2210.3, medium-impact safety glasses to AS/NZS 1337.1, and hard hat to AS/NZS 1801.
- 10PPE — Provide tool lanyards for nippers and tying tools when working above 2 m, and supply electrolyte hydration and cooling vests when WBGT exceeds site heat-stress threshold.
Applicable Codes of Practice
Reinforcement work triggering impalement-from-fall risk is HRCW under s291, mandating a SWMS prepared, consulted and kept until work ends.
Specifies bar grade, ductility class and impalement-cap performance, directly governing material handling assumptions and safety cap selection on site.
Clauses on repetitive force, sustained postures and bundle handling apply directly to bar tying, lifting and placement tasks.
Governs spreader bar selection, lift planning, exclusion zones and dogger communication for all bundled reo crane lifts onto the deck.
High-Risk Construction Work triggered
Steel fixers routinely work on elevated decks, formwork tops and slab edges where a fall onto vertical starter bars is reasonably foreseeable.
Reo placement near temporary site power, embedded conduits and overhead lines creates contact and induction risk requiring isolation verification.
PCBUs must prepare the SWMS in consultation with workers, supply it to the principal contractor, monitor compliance, and retain records; penalties under WHS Reg 2025 are substantial and indexed annually.

Worked example
On a six-level residential build, the steel-fixing leading hand opens this SWMS at the 6:45 am pre-start under the site shed awning with a crew of four fixers and the crane dogger. Today's task is placing and tying the Level 3 suspended slab over previously poured columns with 600 mm vertical starter bars projecting through the formwork. Working through the hazard register, the crew flags two live exposures: impalement on the uncapped column starters and a forecast 34°C afternoon. Controls selected from the document include immediate installation of mushroom safety caps on every starter before deck access, a rotation roster swapping tying and placing duties every 90 minutes, and rescheduling the heaviest bundle lift to 9 am before deck temperature peaks. Each worker signs the HRCW sign-on register acknowledging they have read the SWMS, understand the spreader-bar exclusion zone, and have been issued cut-D gloves and impact eyewear. At 11 am the dogger identifies that incoming N20 bundles weigh 180 kg more than planned; the leading hand pauses work, annotates the SWMS change log, re-briefs the crew on the revised exclusion radius, and obtains fresh sign-on before lifts resume — demonstrating the document functioning as a live control, not a filing-cabinet artefact.
