Psychosocial Hazards in Construction: Regulatory Requirements and Practical Controls

Regulation 55C of the WHS Regulation 2025 requires PCBUs to manage psychosocial risks using the same hierarchy of controls that applies to physical hazards. This means psychosocial hazards must be identified, assessed, and controlled through elimination, substitution, isolation, engineering controls, administrative controls, and personal protective measures in that order of priority. The regulation explicitly rejects the historical approach of treating psychosocial hazards as intangible or unmanageable issues that can only be addressed through employee assistance programs and resilience training. A PCBU must first attempt to eliminate the psychosocial hazard at its source. Where elimination is not reasonably practicable, the PCBU must minimise the risk so far as is reasonably practicable by working down the hierarchy. For construction businesses, this represents a paradigm shift. Psychosocial risk management is no longer a human resources function operating in parallel with the safety management system. It is an integrated component of the WHS framework that must be documented, monitored, and reviewed with the same rigour as physical risk management.

The construction industry presents a distinctive profile of psychosocial hazards that must be specifically addressed in risk assessments. Time pressure is endemic in construction where liquidated damages, milestone payments, and weather dependencies create sustained schedule pressure that flows from project managers through to individual trades. Bullying and harassment remain disproportionately prevalent in construction, driven by hierarchical subcontracting structures, competitive trade culture, and transient workforce relationships that reduce accountability. Fatigue is a significant risk factor, particularly in projects with extended shift patterns, fly-in fly-out rosters, or early morning starts combined with long commutes. Lone work occurs frequently in construction during site establishment, after-hours concrete pours, security duties, and specialist maintenance tasks. Client aggression affects construction workers on occupied premises and in residential settings. Exposure to traumatic incidents including serious injuries and fatalities is higher in construction than in almost any other industry. Each of these hazards must be specifically identified, assessed, and controlled in the PCBU's psychosocial risk management process.

SafeWork NSW has introduced a six-monthly reporting obligation for psychosocial hazard management in prescribed high-risk industries including construction. PCBUs must report on the psychosocial hazards identified in their workplaces, the risk assessments conducted, the control measures implemented, and the outcomes of any reviews or evaluations of those controls. The report must include data on psychosocial-related incidents, complaints, and workers compensation claims lodged during the reporting period. It must describe consultation arrangements with workers and health and safety representatives on psychosocial matters. The report must identify any changes to work design, workload, rostering, or management practices implemented during the period to address psychosocial risks. This reporting obligation is not merely administrative. It creates a documented record that regulators can use to assess whether a PCBU is taking reasonably practicable steps to manage psychosocial risks over time. Businesses that submit reports showing no identified hazards and no control measures will attract regulatory scrutiny. Construction PCBUs should establish internal data collection systems that feed directly into the six-monthly reporting cycle.

Psychosocial hazards must be integrated into existing SWMS and risk assessment processes rather than managed through separate standalone documents. When preparing a SWMS for high-risk construction work, the PCBU should consider whether the task involves psychosocial risk factors such as working alone, working at height where fear and anxiety affect performance, working under extreme time pressure, or performing tasks with a high consequence of error. The risk assessment should identify these psychosocial hazards alongside the physical hazards and apply appropriate controls. For example, a SWMS for work at height might include controls for both fall prevention and the psychological stress of working at elevation, such as task familiarisation, buddy systems, and clear communication protocols. Pre-start meetings should include discussion of psychosocial factors including fatigue levels, personal stressors that may affect concentration, and any concerns about the day's tasks. Incident investigation procedures must be expanded to include psychosocial contributing factors. Near-miss reporting systems should capture psychosocial precursors such as rushing, distraction, and interpersonal conflict that may have contributed to the event.
