A Safe Work Method Statement (SWMS) is a legal document required for all high-risk construction work (HRCW) in Australia. It describes the work, identifies hazards at each step and sets out the control measures to manage those risks.
This guide walks through building a SWMS from scratch, step by step, from identifying the high-risk work through to briefing the crew and collecting sign-on. It also explains how a SWMS differs from a JSA and when each document is required.
Before you start
Gather your SWMS template, a risk matrix and the relevant codes of practice from SafeWork Australia for the type of HRCW you are performing. You will also need project-specific information: scope of work, site location, principal contractor details and a list of personnel involved. Review your compliance requirements before you begin.
Before writing the SWMS, complete a risk assessment for the broader task if one does not already exist. The SWMS builds on that assessment by focusing on the high-risk construction work.
Step-by-step SWMS
1. Identify the high-risk construction work
Confirm the work falls within one or more of the 18 HRCW categories in regulation 291 of the model WHS Regulations (19 in the ACT and Victoria). If it does not, a SWMS is not legally required. Common triggers include work at heights above 2 metres, excavation deeper than 1.5 metres, demolition and confined space entry.
2. Break the job into steps
List each step in sequence from site setup through the active work phase to pack-down. Keep steps specific. "Set up exclusion zone around excavation" is useful. "Prepare site" is too vague. Involve the workers who will perform the task.
3. Identify hazards at each step
For every step, identify what could go wrong: falls, struck-by hazards, collapse, electrical contact, engulfment and plant-related risks. Talk to the crew. Workers who have done the task before spot hazards a desktop review will miss.
4. Assess risk using a risk matrix
Rate likelihood and consequence for each hazard. Record the inherent risk rating (before controls) and the residual rating (after controls) to demonstrate risk is reduced to an acceptable level.
5. Determine control measures
Apply the hierarchy of controls in order of effectiveness:
- Elimination - remove the hazard entirely
- Substitution - replace with something less hazardous
- Isolation - separate people from the hazard
- Engineering - guardrails, shoring, edge protection
- Administrative - permits, procedures, signage
- PPE - harnesses, hard hats, hearing protection (last resort)
6. Document the SWMS
Record everything in your template: principal contractor's name, PCBU, HRCW activity description, site location, date and all workers. Each hazard, its risk rating and the specific control measures must be clearly documented.
7. Brief the crew and collect sign-on
Every worker must read, or be read, the SWMS and sign the sign-on sheet before starting work. This is often done as part of a toolbox talk. Anyone arriving after the briefing must be inducted individually.
SWMS vs JSA
Both documents identify hazards and controls for a task, but they carry different legal weight in Australia.
| Aspect | SWMS | JSA (Job Safety Analysis) |
|---|---|---|
| Legal status | Required by WHS Regulations for HRCW | Not specifically required by legislation |
| When required | Before any HRCW begins | Any task with significant risk |
| Scope | Specific to high-risk construction work | Any industry, any task |
| Sign-on | Mandatory worker sign-on | Best practice, not mandated |
| Review triggers | Before work starts, after incident, when conditions change | Same triggers apply |
| Common in | Construction (Australia) | Mining, oil and gas, manufacturing (all countries) |
Download a JSA template or a combined construction JSA/SWMS template if your project requires both documents.
High-risk construction work
Regulation 291 of the model WHS Regulations defines 18 categories of HRCW, 19 in the ACT and Victoria. Any construction work involving one or more of these requires a SWMS before work can start. The table shows ten of the most common.
| HRCW activity | Example |
|---|---|
| Work at height (risk of fall greater than 2 m) | Scaffolding, roof work, edge work |
| Excavation deeper than 1.5 m | Trenching, basement excavation |
| Demolition | Structural demolition of load-bearing elements |
| Work near live electrical installations | Within exclusion zone of overhead power lines |
| Confined space entry | Tanks, pits, vaults, manholes |
| Diving work | Underwater construction, inspection |
| Work on or near a road, railway or other traffic corridor in use | Kerbside works, rail corridor maintenance |
| Work on or near pressurised gas mains or piping | Connecting to or cutting into a live gas main |
| Work in areas with movement of powered mobile plant | Excavators, trucks and loaders on site |
| Work involving tilt-up or pre-cast concrete | Panel erection, propping and bracing |
Regulatory requirements
In Australia, regulation 299 of the model WHS Regulations makes a SWMS mandatory for all 18 categories of HRCW listed in regulation 291, 19 in the ACT and Victoria. On a construction project, the principal contractor must take all reasonable steps to obtain a copy of the SWMS before HRCW starts (regulation 312). Penalties for non-compliance can exceed $500,000 for a PCBU. The SWMS must be readily accessible to the workers carrying out the HRCW, and reviewed and revised as necessary whenever its control measures must be reviewed under regulation 38: for example when a control is not working (a notifiable incident is one sign), before a change at the workplace that could create a new risk, when a new hazard is identified, or when a health and safety representative asks.
The United States does not require a SWMS by name. OSHA uses Job Hazard Analysis (JHA) and Activity Hazard Analysis (AHA) under 29 CFR 1926. The United Kingdom uses method statements and risk assessments under CDM Regulations 2015.
Going digital with MapTrack
Paper SWMS documents get damaged on site, go missing and become outdated without anyone noticing. With MapTrack, you can create SWMS using digital forms that enforce completion of every required field. Workers sign on using a tablet or phone, with timestamps and GPS location captured automatically.
Track SWMS currency, expiry dates and review schedules through compliance management. When a regulator asks to see the SWMS for a specific activity, retrieve it in seconds instead of searching filing cabinets. Use the mobile app to brief crews and collect signatures on site, even without reception. Documents sync when connectivity is restored, giving you a complete digital audit trail.
