A subcontractor’s safe work method statement (SWMS) needs to make the high-risk construction work and its controls understandable to the people using it. A review should test that understanding alongside the resources, conditions and coordination needed to carry out the method.
In our consulting work, we have encountered catch-all documents loaded with technical requirements that workers struggle to interpret. We have also observed managers treating a signed document as evidence that their obligations have been met. A signature does not establish that controls have been implemented or that work is being carried out in accordance with the SWMS.
The review needs to ask what the document helps people do, what is difficult to apply and what the project team must resolve. The approach below combines practical inquiry with document and field checks. Confirm the duties applying to your jurisdiction and project.
Start with the contractor and the people who will carry out and supervise the work. Ask them to explain the proposed sequence, equipment, access and interaction with other activities. Explore what they expect to change during the job and what support they need from the project team.
Our Principal Consultant Robert O'Neill, describes his starting point as “no blame, no judgement, just open curiosity”. He talks with workers to learn about their constraints and what has worked well in the past. Begin with an open invitation to explain the work, then follow what people tell you before narrowing the discussion to particular requirements.
He has heard workers describe having raised concerns previously without seeing action, becoming frustrated with documents written without an understanding of the task, and being reluctant to be seen as a blocker. These are observations from his practice, not an explanation for every workplace. Explore what makes it easier or harder for people on your project to raise a concern, and how earlier concerns were handled.
Include the project arrangements that shape the task, such as delivery timing, procurement, available space and supervision. Identify which high-risk construction work categories apply and who must prepare, use and review the SWMS.
Queensland’s guidance places SWMS duties on the PCBU carrying out high-risk construction work. Victoria’s guidance describes duties for employers and self-employed people under its OHS framework. Check the relevant regulator’s requirements; terminology, project thresholds and plan duties vary.
Ask the people using the SWMS to explain the relevant steps and controls in their own words. Explore where they need clarification; use the discussion to improve the method and its explanation, rather than making it a test of the worker.
WorkSafe Victoria advises that additional information should not obscure the focus on high-risk construction work. It also calls for clear, accessible instructions and the removal of site-irrelevant content from generic SWMS. Retain necessary technical detail while making the applicable method clear.
Queensland’s guidance identifies the work, hazards and risks, control measures, and how the controls will be implemented, monitored and reviewed. It separately recommends identifying and administrative information, such as an ABN if the business has one. Distinguish required content from useful record details rather than treating every template field as a universal statutory requirement.
Check the current version, work location and responsible people so the document can be connected with the task and used by those who need it.
Review each method alongside the project’s safety arrangements. Queensland’s WHS management-plan guidance addresses responsibilities, consultation and coordination, incident arrangements, site rules and the handling of SWMS. WorkSafe Victoria provides a health and safety coordination-plan template. Confirm the applicable plan duties and requirements for your project.
For illustration, an excavation contractor and a delivery contractor might each describe their controls while leaving a shared access route unresolved. Bring the relevant people together to establish responsibilities, sequencing and the checks needed before the activities overlap. This example identifies a coordination question; it does not specify excavation or traffic controls.
Robert maps what workers describe against the wider work system: the relationships between people, equipment, tasks and organisational arrangements. His approach draws on several bodies of thinking, including Sidney Dekker’s Safety Differently, Erik Hollnagel’s Safety-II, Human and Organisational Performance (HOP), and David Woods’ work on resilience and cognitive systems.
He then brings teams from different functions together to explore options and design improvements collaboratively. For a construction project, involve the roles able to address the constraints identified, which may include supervision, planning, engineering, procurement and subcontractor management.
Use the discussion to identify changes to the work, alongside any document revision. Agree who can make each decision, what resources are needed and how the change will be checked. Report back to workers on what was decided, what remains unresolved and why. The practical aim is to improve the work itself.
Choose verification methods suited to the hazard, control and stage of work. Check whether the controls described in the SWMS are available, being used and functioning as intended. Depending on the control, this may require observation, inspection, maintenance records, testing or competent specialist assessment.
Ask people to explain how the method is working and what has changed. Where practice differs from the SWMS, investigate the circumstances without assuming the cause. Equipment, sequencing, supervision or the method itself may need attention; establish what is happening before deciding on the response.
Record the task, location, conditions and evidence examined, along with what was outside the review. Completion of a check is a record of an activity; the findings must explain what it established about the control. An observation of one task does not establish safety across every shift or location.
Queensland and Victorian guidance require affected high-risk construction work to stop immediately, or as soon as it is safe to do so, when it does not comply with its SWMS. Understanding the circumstances must accompany the required action. Follow the jurisdiction’s requirements for review, revision and resumption.
Work with the relevant people to resolve the concern, provide necessary support and review the method. Do not simply amend the document to endorse an uncontrolled practice. Record the action owner, changes and checks supporting resumption; communicate revisions and meet applicable availability and retention requirements.
Keep advice, verification and authorisation to proceed distinct. People with operational authority make the work decisions, and duty holders retain their responsibilities.
Within an agreed scope, Work Safety Hub can review how your SWMS process, project safety plan and contractor monitoring connect. The review can identify gaps, practical priorities and the evidence needed to assess controls, with its sampling limits made clear. It does not guarantee compliance or authorise work.
