Formwork collapse is one of the most catastrophic construction failure modes, capable of killing multiple workers in a single event. The WHS Regulation 2025 classifies work involving structural alteration that requires temporary support — including formwork — as high risk construction work requiring a documented SWMS. Formwork systems exceeding 4 metres in height must be designed by a competent engineer. This template covers formwork erection, loading, pre-pour inspection, stripping, and re-propping with controls mapped to the binding Formwork Code of Practice effective 1 July 2026 under Section 26A.
WHS Regulation 2025 Part 4.4 — High Risk Construction Work
Work involving structural alteration that requires temporary support
Formwork (binding 1 July 2026 under Section 26A)
Yes — effective 1 July 2026. Non-compliance is admissible as evidence of breach.
Not specifically required, but engineer design mandatory for formwork >4 m
| Hazard | Consequence | Likelihood |
|---|---|---|
| Formwork collapse during concrete pour due to inadequate bracing or overloading | Multiple fatalities, crush injuries | Unlikely |
| Premature stripping of formwork before concrete reaches design strength | Structural collapse, multiple fatalities | Possible |
| Workers struck by falling formwork panels during erection or dismantling | Traumatic brain injury, fractures, death | Possible |
| Falls from height during formwork erection on elevated structures | Death, spinal injuries | Likely |
| Formwork component failure — prop collapse, bearer buckling, tie blowout | Localised collapse, crush injuries | Possible |
| Manual handling injuries from heavy formwork panels and props | Musculoskeletal injuries, chronic back pain | Likely |
Formwork system collapsed during concrete pour due to inadequate propping and failure to follow engineer design. Multiple workers injured in the collapse.
2023 — SafeWork NSW v Universal Propping Pty Ltd [2023]
Formwork for a multi-storey car park collapsed during pouring, injuring four workers. Investigation found props were not plumb, bracing was incomplete, and no pre-pour inspection was documented.
2022 — WorkSafe Victoria Formwork Enforcement Reports
Our WHS consultants develop formwork SWMS with engineer design integration, pre-pour checklists, and stripping sequences that satisfy regulator expectations and prevent catastrophic collapse.
