What problems arise when construction sites can’t prove who was on-site during accidents?

The Time and People solution

When construction sites can’t definitively prove who was on-site during an accident, significant problems arise regarding liability, Work Health and Safety (WHS) investigations, and compliance with both legal obligations and increasingly stringent Child Safe Standards, as of December 2025.

Construction operates as a multi-tiered system. Head contractors engage subcontractors, who may further subcontract specialised work. This creates a fluid workforce, with numerous individuals from different companies potentially present daily. Accurate record-keeping of all personnel on-site is crucial, but often relies on paper-based sign-in sheets or basic digital systems. These methods are vulnerable to inaccuracies or manipulation. In Australia, WHS regulations require duty holders to manage risks to health and safety, including identifying who is exposed to those risks. Child Safe Standards, particularly Standard 5 (Equitable and Respectful Behaviour), now require robust systems to identify and manage risks posed by all adults on-site, especially near education facilities or childcare centres. Similar requirements exist in the US under OSHA regulations and state-level licensing for contractors. Investigations following an incident – whether a worker injury or a concern relating to a child’s safety – are severely hampered without reliable attendance data. Establishing a clear chain of events and identifying witnesses becomes difficult, potentially leading to legal challenges and regulatory penalties.

Ultimately, the inability to verify on-site presence complicates incident response, hinders accurate risk assessment, and undermines compliance with evolving safety and child protection frameworks in both Australia and the US.
