Formwork erection, stripping, and reshoring for cast in-situ concrete structures is one of the highest-risk construction activities on Australian sites, combining work at height, temporary structural loading, manual handling of heavy timbers and steel, and pour-sequence coordination. Workers assemble wall panels, column boxes, beam soffits, and suspended slab decks that must support wet concrete loads often exceeding 25 kPa before the permanent structure can carry itself. Under WHS Regulation 2025 Part 6.3 and the WHS Act 2011, formwork above 2 metres or capable of collapse triggers mandatory High Risk Construction Work classification, requiring a documented SWMS before work commences. AS 3610.1:2018 prescribes minimum design, erection, and stripping criteria, while the FWPA Formwork Code of Practice sets duty-holder obligations for principal contractors and formwork subcontractors. A site-specific SWMS is the primary control instrument linking the engineered formwork design to the workers actually building, loading, and dismantling it.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Specify proprietary modular table-form and jump-form systems with integrated guardrails to remove repetitive deck-edge exposure and hand-built timber decks where the design permits.
- 2Elimination — Pre-assemble wall and column forms at ground level on jigs before craning into position, eliminating high-level assembly and reducing fall-from-height exposure entirely.
- 3Substitution — Replace timber-bearer-and-prop systems with engineered aluminium or steel proprietary shoring rated and certified by the manufacturer to AS 3610.1:2018 design loads.
- 4Substitution — Substitute heavy LVL bearers with lighter engineered alternatives below 20kg per length to bring single-person lifts within manual handling limits per Code of Practice Hazardous Manual Tasks.
- 5Engineering — Install perimeter scaffold or proprietary edge protection systems to AS/NZS 4994.1 before any deck-laying commences, with mid-rail, toprail, and toeboard to all open edges and penetrations.
- 6Engineering — Erect formwork strictly to the formwork engineer's stamped design drawings including back-propping and reshoring schedules; no field modification without RPEQ/CPEng written approval.
- 7Administrative — Conduct pre-pour formwork inspection and sign-off by the formwork engineer or competent person against AS 3610.1 Section 5 checklist before any concrete placement begins.
- 8Administrative — Establish hard-barricaded exclusion zones below all stripping operations, controlled by spotter with two-way radio, and enforce pour-sequence permits aligned to concrete strength test results.
- 9Administrative — Deliver daily pre-start toolbox covering the day's pour sequence, prop loads, stripping times, and SWMS sign-on; rotate manual handling tasks to limit cumulative spinal loading.
- 10PPE — Mandatory hard hat to AS/NZS 1801, safety glasses, cut-5 gloves, steel-midsole and steel-cap boots to AS/NZS 2210.3, hi-vis to AS/NZS 4602.1, and harness with shock-absorbing lanyard to AS/NZS 1891.1 where edge protection is incomplete.
Applicable Codes of Practice
Sets mandatory design loads, prop spacing, stripping strengths, and inspection holds — the engineering baseline every formwork SWMS must implement on site.
Triggers mandatory SWMS, principal contractor consultation, and worker sign-on duties for formwork above 2m and risk-of-collapse structures.
Defines PCBU duties for SWMS preparation, review, and worker consultation under WHS Act s47, with specific formwork stripping exclusion-zone guidance.
Prescribes guardrail loads, geometry, and installation for deck-edge protection before formwork deck laying — referenced in clause 4.4 of the SWMS.
High-Risk Construction Work triggered
Deck laying for suspended slabs, column-form access, and stripping operations routinely place workers above 2 metres on incomplete decks and edges.
Formwork and falsework are temporary support carrying the full wet concrete load — often above 25 kPa — until the permanent structure reaches stripping strength, so the whole erection, pour and strip cycle depends on that temporary support to prevent collapse.
PCBU and formwork subcontractor must consult workers in SWMS preparation, retain the signed SWMS for two years (or duration of any incident investigation), and produce on regulator demand; penalties for Category 1 reckless conduct breaches are substantial and indexed, with current maximum following the prevailing WHS schedule.
Who this is for

- →Principal contractors managing multi-storey concrete builds
- →Site supervisors and leading hands directing formwork crews
- →Formwork engineers signing off pour and strip permits

Worked example
On a mid-rise residential project the formwork leading hand opens the Formwork Erection & Stripping SWMS at the 6:30am pre-start before a Level 4 slab pour. He walks the crew of seven through the hazard register on the printed SWMS, calling out today's specific risks: open deck edges at the eastern lift core where edge protection was relocated overnight, and the back-propping schedule for Level 3 which must remain undisturbed until the 7-day cylinder break results clear. Two workers flag that the perimeter handrail at gridline E is missing a mid-rail — the supervisor stops, marks the control as not-yet-verified on the SWMS, and dispatches a carpenter to reinstate it to AS/NZS 4994.1 before deck loading resumes. The crew sign on against the SWMS, including a new labour-hire concreter who is walked through the exclusion zone map for the strip-out happening one level below. During the pour, the engineer's nominated competent person identifies a prop that has shifted under load; work pauses, the SWMS dynamic review section is annotated, the prop is reset and re-wedged, and the crew re-sign before pouring resumes. At smoko the supervisor photographs the annotated SWMS and uploads it to the site compliance folder, satisfying the record-keeping duty under WHS Regulation 2025.

Frequently asked questions
Is formwork high risk construction work?
Yes, on two counts that run in parallel. Section 291(a) applies because deck laying for suspended slabs, column-form access and stripping routinely put workers above two metres on incomplete decks and open edges. Section 291(e) applies for the whole erection, pour and strip cycle, because the falsework is temporary support carrying full wet concrete load — often above 25 kPa — before the permanent structure can carry itself. Section 299 then requires the SWMS prepared before work starts, with worker consultation and sign-on, and AS 3610.1:2018 sets the engineering baseline the document has to implement.
Does this cover stripping and back-propping, or only erection?
All three, as one continuous cycle, and that is deliberate — the collapses happen at the joins between them. Premature stripping before the concrete reaches the stripping strength specified under AS 3610.1 is carried as its own high-priority hazard, separate from erection failure, and the back-propping and reshoring schedule is erected to the engineer's stamped drawings and left undisturbed until strength results clear. The worked example holds the Level 3 back-props in place until the seven-day cylinder break results come back, regardless of what the program wants.
Can we modify the formwork on site if something does not fit?
No. Formwork is erected strictly to the formwork engineer's stamped design drawings, including the back-propping and reshoring schedule, and no field modification proceeds without written engineering approval. The reason that control is absolute is that the failure mode is invisible: a prop shifted 300 mm to clear a service run, or a bearer span stretched by one module, changes the load path without changing anything a worker on the deck can see. The pre-pour inspection and sign-off by a competent person against the AS 3610.1 checklist is the hold point that catches it.
How do we protect the level below during strip-out?
Hard-barricaded exclusion zones under every stripping operation, controlled by a spotter on two-way radio, with the exclusion map briefed to anyone new on site — the worked example walks a new labour-hire concreter through it before he picks up a tool. Falling props, bearers and panels are a high-priority hazard during strip-out, and the stripped material becomes a second one in the laydown: protruding form ties and nails in used formply cause puncture wounds and impalement, which is why steel-midsole boots are specified rather than plain steel-cap.
What happens when a control fails part-way through a pour?
You stop, annotate and re-sign, and the document is structured for that rather than for filing. In the worked example a prop shifts under load mid-pour: work pauses, the dynamic review section is annotated, the prop is reset and re-wedged and the crew re-sign before concrete resumes. Earlier the same morning a missing mid-rail at gridline E is marked as not-yet-verified and reinstated to AS/NZS 4994.1 before deck loading continues. The annotated document is photographed and filed to satisfy the record-keeping duty. It is an editable Microsoft Word file bought once.
