What is a excavation and trenching swms?
An excavation and trenching Safe Work Method Statement (SWMS) is the high-risk construction work document that sets out how excavation work, particularly trenches deeper than 1.5 metres, will be carried out safely. It records the job and site, the workers and their tickets, the plant used, and a row for every work step showing the hazard, the risk rating, the controls and how each control is implemented, monitored and reviewed. For excavation it focuses on preventing collapse through shoring, benching or battering, locating buried services before you dig, controlling spoil, providing safe access and egress, and testing the atmosphere where a trench can become a confined space.
An excavation and trenching SWMS matters because a trench collapse gives a worker no warning and no time to escape, and even a shallow fall of earth can bury and kill. Excavation work in or near a shaft or trench with an excavated depth greater than 1.5 metres, or a tunnel, is named in the high-risk construction work categories of the model WHS Regulations (in Victoria, the Occupational Health and Safety Regulations 2017), which require a SWMS before the work starts. This template keeps the ground-support and service-location controls explicit so a crew cannot enter an unsupported trench under time pressure, ties the controls to the specific site and asset, and gives you the dated, signed evidence a regulator or principal contractor expects.

Benefits of using this excavation and trenching swms
- Collapse prevention: shoring, benching and battering are written as controls per step, so the crew never enters an unsupported trench to save time.
- Services located: a required Before You Dig Australia (BYDA) enquiry and potholing stops an excavator striking gas, power, water or comms lines.
- Spoil control: keeping spoil back from the edge removes the surcharge load that causes many trench-wall collapses.
- Safe access: dedicated access and egress controls give workers a way out within reach along the trench, not a scramble at one end.
- Atmosphere aware: an atmospheric-testing step catches the point where a deep or enclosed trench becomes a confined space with its own hazards.
- Regulatory fit: a trench or shaft deeper than 1.5m is named high-risk construction work, and this template captures the hazard, control and review detail the regulation requires.
- Crew sign-on: every worker signs on, so the whole crew shares the same understanding of the ground support, services and exclusion zones.

What to include in a excavation and trenching swms
This excavation and trenching swms covers 10 key areas:
- Job description, site or project, principal contractor and the area or asset worked on
- SWMS number, date prepared and revision, with the person responsible for the SWMS
- Workers and roles, plus tickets for excavator, dogging or other plant used
- Plant and attachments used, and the ground-support method: shoring, benching or battering
- Before You Dig Australia (BYDA) plans, service locating results and potholing before mechanical digging
- Trench depth, soil type and water conditions, and the exclusion zone around the excavation
- Work steps in order, one row per step, covering set up, digging, entry and backfill
- Hazard, risk rating, controls and residual risk for each step
- Spoil placement, edge protection, access and egress points, and plant separation from workers
- Atmospheric testing where the trench is a confined space, emergency plan and worker sign-on
How to use this excavation and trenching swms
- Plan the dig and locate services first: Define the excavation, the site and the asset, lodge a Before You Dig Australia (BYDA) enquiry, and locate and pothole buried services before any mechanical digging. A trench or shaft deeper than 1.5 metres is named high-risk construction work, so the SWMS must be ready and understood before the excavator turns a bucket, not written up after the trench is open.
- Choose the ground-support method: Assess the soil type, depth, water and nearby loads, then select shoring, benching or battering to prevent collapse. Record which method applies to each part of the trench, because ground conditions change along a run, and a control that holds in stable clay may be useless in loose or saturated ground a few metres on.
- Control spoil, access and the exclusion zone: Set spoil back from the trench edge so it does not surcharge the wall, mark an exclusion zone around the excavation, and provide safe access and egress such as a ladder or ramp within reach of workers in the trench. Keep plant and its swing separated from workers, and never let anyone work beneath a suspended load or a swinging bucket.
- Rate hazards, test atmosphere and apply controls: For each work step, score the risk and apply controls, noting who implements each and how it is monitored. Where a deep or enclosed trench can become a confined space, test the atmosphere before entry, because gases can collect in a trench with no obvious warning and a worker who enters without testing may be overcome.
- Sign on, monitor and review: Every worker reads and signs on to the SWMS, and the supervisor authorises the job. Keep it at the work front, stop and revise it if the ground, the weather or the method changes, and review it after the job or any incident so the collapse-prevention controls stay current for the next crew.

Prepare an excavation and trenching SWMS before the work starts, and review it whenever the ground conditions, the depth, the weather or the crew changes. Rain can turn stable ground unstable overnight, so reassess the trench walls and support at the start of each shift and after any weather event.
Stop work and revise the SWMS if a control is not being followed or is not working, then re-communicate it and have the crew sign on again. Formally review the master SWMS after any incident or near miss, after a change to the ground-support method, or when a relevant standard or regulation changes.
