Incident date



Scaffold collapse


Macquarie Park

Incident overview

Two formworkers were working on a multi-storey mixed-use construction in Macquarie Park. They were on a concrete slab working beside the base of scaffolding approximately 9 stories high when it collapsed, crushing both workers. One worker was transferred to hospital with critical injuries while the other died at the scene.

Safety information

PCBUs are reminded of their duty to identify hazards and manage risks to health and safety in accordance with the provisions of the Work Health and Safety Act 2011 and Work Health and Safety Regulation 2017.

PCBUs are reminded to consider reasonable and practicable control measures to manage the risk of scaffold collapse:

  • Ensure the scaffold is stable at all times, including during erection, in situ, during and after any alterations, and when dismantling.
  • Ensure the scaffold can withstand all anticipated loads, including the weight of workers, all stored material and any loads due to weather such as wind and rain (particularly where containment sheeting is used).
  • Ensure dismantled scaffold components are not stored on the existing scaffold unless it is designed to withstand these loads.
  • Know the duty rating (light, medium, heavy or special) and number of decks that can be loaded within a bay.
  • Ensure the scaffold is adequately tied to its supporting structure, in accordance with instructions from a competent person. Consult with the scaffold designer, manufacturer, supplier or an engineer, and prevent unauthorised removal or changes.
  • Develop systems of work that allow construction activities such as bricklaying, painting, rendering, glazing and cladding installation to be completed without unplanned changes to, or removal of, scaffold ties, e.g. work down from the top of the building as the scaffold is progressively dismantled, or relocate ties so they do not interfere with the work.
  • Ensure altering or partially dismantling the scaffold does not weaken it, e.g. removing returns or adjacent bays may require additional ties or bracing on the remaining scaffold.
  • Ensure only competent persons with a relevant class of high risk work licence undertake scaffolding work including making alterations.
  • Protect the scaffold from damage by vehicles, plant, equipment or materials.
  • Use a scaffold that is suitable for the tasks and construction process.
  • Provide all workers adequate information, instruction, training and supervision regarding the control measures required to prevent the collapse of the scaffold.
  • Have a competent person who holds the same or higher class of high risk work licence appropriate to the class of scaffolding regularly inspect the scaffold, to ensure it has not been modified or altered by unauthorised persons.
  • Prepare a safe work method statement for all high risk construction work.
