Gate collapse charges: three checks for designers and installers

WorkSafe Victoria: Gate Collapse Charges Highlight the Need for Design and Welding Assurance

News & Updates | 11 November 2026

WorkSafe Victoria announced on 4 November 2026 that a fencing company had been charged after a steel gate collapsed at a Tullamarine hotel in November 2024, seriously injuring a member of the public.

WorkSafe alleges shortcomings involving a documented welding procedure, competent and qualified welding personnel and supervision, and inspection and testing of welds before supply and installation. These remain allegations before the court, not findings of guilt.

What should designers, manufacturers and installers take from this?

1. Structural design: AS/NZS 1170

Gates and their supporting structures must be designed for relevant actions. This includes self-weight and applicable wind loads, with AS/NZS 1170.2 addressing wind actions. Gate size, exposure, supporting posts, connections and foundations matter. A standard detail does not prove that a particular installation is suitable for its site.

Practical check: obtain design documentation that addresses the specific gate, support structure and site conditions.

2. Welding quality: AS/NZS 1554.1

For structural steel welding where it applies, AS/NZS 1554.1 addresses procedures, qualifications and inspection. Appearance alone is not adequate evidence that a critical welded connection meets its requirements. The relevant design and specification should set the appropriate acceptance and inspection criteria.

Practical check: request suitable welding procedure, personnel competency and inspection records from your fabricator.

3. Supply-chain assurance: know your product

Whether gates are locally fabricated, subcontracted or imported, the business designing, selecting or installing them should understand what is being supplied and what evidence supports its suitability. Outsourcing fabrication does not automatically remove duties attaching to your own role. Specific legal responsibilities depend on the circumstances and applicable law.

Practical check: verify drawings, materials, fabrication records, traceability and installation documentation before handover.

The takeaway

Know how it was designed, who manufactured it, and what evidence demonstrates it is suitable for the site. Document the decisions before something goes wrong.
