Product Overview

Summary: This Structural Integrity Assessment Safe Operating Procedure provides a clear, defensible framework for inspecting and verifying the safety of buildings, structures and critical assets. It supports Australian organisations to identify structural defects early, manage risk to workers and the public, and demonstrate compliance with WHS duties and relevant Australian Standards.

This Structural Integrity Assessment SOP sets out a consistent, evidence-based approach for planning, conducting and documenting structural inspections across a wide range of assets – from commercial buildings and industrial plants to civil structures such as bridges, retaining walls and towers. It clarifies when assessments are required, how they are to be carried out, what must be recorded, and how defects are to be classified and escalated. The procedure is written specifically for the Australian context, aligning with WHS legislation, engineering practice and asset management expectations.

By implementing this SOP, organisations can move away from ad‑hoc inspections and undocumented engineering judgments to a structured, repeatable system that stands up to regulator and client scrutiny. The document helps duty holders demonstrate that they have systematically identified structural hazards, assessed the likelihood and consequence of failure, and implemented controls in line with the hierarchy of control. It also supports better lifecycle planning by integrating structural assessment outcomes with maintenance programs, capital works planning and change management processes, reducing the risk of sudden failures, costly outages and reputational damage.

Key Benefits

• Ensure a consistent, defensible methodology for structural inspections and assessments across all sites and assets.
• Reduce the risk of structural failure, collapse and associated injuries through early detection and rectification of defects.
• Demonstrate compliance with WHS duties, Australian Standards and engineering due diligence requirements.
• Streamline communication between engineers, site teams and management with clear defect classification and escalation pathways.
• Support long‑term asset reliability and budgeting by integrating assessment findings into maintenance and capital planning.

Hazards Addressed

• Partial or full structural collapse of buildings, platforms, scaffolds and temporary works
• Falling structural elements such as façade panels, cladding, beams or overhead services supports
• Instability of retaining walls, embankments and excavations due to inadequate structural support
• Failure of load‑bearing components under static or dynamic loads (e.g. storage racking, mezzanines, walkways)
• Progressive deterioration of structures due to corrosion, fatigue, concrete spalling or termite damage
• Uncontrolled structural modifications or overloading beyond design capacity
• Secondary hazards arising from structural failure, such as falling from heights, impact injuries and entrapment
