SWMS and Pre-Start Checklists: Why the Start of the Shift Matters
A safe shift starts before the first cone goes out.
Completing the Safe Work Method Statement (SWMS) and pre-start checklist before work begins may seem like a small part of the day, especially when there is a tight setup window and plenty to get organised. But these checks are not just paperwork. They are there to make the crew stop, look at the site, think about the risks and confirm that everyone is ready before work starts.
When they are completed at the right time, they can help identify problems before they become incidents.
When they are completed hours into a shift or after the work has finished, they lose much of that value.

Why Timing Matters
A pre-start is a control, not just a record.
Working through it before setup gives the crew an opportunity to look at the actual conditions in front of them. What is the traffic doing? Has the weather changed? Is the plant and equipment ready? Are there any hazards around the work area?
These are questions that need to be answered before people are standing in front of live traffic.
The Final Check Between the Plan and Reality
A Traffic Guidance Scheme (TGS) may have been prepared well before the crew arrives at the site.
The SWMS and pre-start provide an opportunity to confirm that the approved arrangements and planned work still make sense for the conditions being faced that morning.
The site may have changed since the documents were prepared. There could be different traffic conditions, weather, access issues, equipment problems or other hazards that need to be considered before setup begins.
Taking a few minutes to identify these things early is much easier than discovering them halfway through the shift.
It Sets the Crew Up
The start of a shift is also an opportunity to get everyone on the same page.
Going through the SWMS with the crew helps make sure everyone understands the work being carried out, the hazards involved, the controls required and their responsibilities.
Traffic Controllers, TMIs, Supervisors and other crew members should know what they are walking into before anyone steps onto the road.
Good communication at the start can prevent confusion later.
Problems Are Easier to Fix Early
A missing device, damaged sign, equipment issue or blocked escape path is much easier to deal with before the worksite is established.
Once traffic is moving and the work has started, making changes can be more difficult and may introduce additional risks.
That is why the pre-start is valuable. It gives the crew a chance to identify issues while they are still relatively easy to fix.
A few minutes of checking can save a lot more time later.
Completing It Later Misses the Point
A checklist completed at lunchtime or after pack-up may provide a record that the form was eventually completed, but it cannot provide the same safety benefit as a pre-start completed before work begins.
The hazards the checklist is designed to identify were already present.
The purpose is not simply to have a completed document. The purpose is to use the process to think about the work before the risks are live.
That difference matters.
We Know How the Start of a Shift Goes
Early starts are not always straightforward.
There may be equipment to load, a client waiting for the road to be opened, a tight setup window, a new site to find, traffic conditions to consider and plenty happening at once.
It can be tempting to think, I’ll complete the pre-start once everything is set up.
But the request is simple:
Complete the SWMS and pre-start on site, before setup begins, with the crew, every shift.
If something is genuinely getting in the way, speak up.
Maybe the app is not loading. There is no signal. The time allowed before the road opens is not realistic. Or perhaps someone is unsure how to complete part of the process.
These are problems that can be addressed.
What cannot be fixed is a problem nobody knows about.
Before You Place the First Cone
Before setup begins, take a moment and ask yourself:
Has the SWMS been read and signed by everyone on the crew today?
Has the pre-start been completed for the plant and equipment being used?
Does the site in front of us match what the TGS and SWMS describe?
Has anything been identified during the pre-start that still needs to be addressed?
Does everyone understand the hazards and their responsibilities?
If something does not look right, do not ignore it.
Raise it with your TMI or Supervisor so it can be assessed and the appropriate action taken.
More Than Compliance
SWMS and pre-start checks are important for compliance, but their value goes beyond having the right paperwork available for an audit.
They create a moment at the beginning of the shift where the team pauses and thinks about the work before getting started.
That moment can identify a hazard, highlight an equipment problem, clarify responsibilities or reveal that something on site is different from what was expected.
That is where the real value is.
Final Thoughts
The SWMS and pre-start checklist only take a few minutes, but those few minutes can make a real difference to how safely a shift starts.
Complete them before work begins, involve the crew, look at the conditions in front of you and speak up if something does not make sense.
The paperwork is there to prompt the thinking. Use it that way.
Because the safest time to find the thing that could catch us out later is before the first cone goes down.
FAQs
When should the SWMS be completed?
The SWMS should be reviewed with the crew before work begins so everyone understands the work, hazards and required controls for the shift.
When should a pre-start checklist be completed?
The pre-start should be completed before setup and before the relevant plant or equipment is put into operation.
Why should a pre-start be completed before setup?
It gives the crew an opportunity to identify hazards, check equipment and compare actual site conditions with the planned work before entering the active work environment.
What if the site conditions don't match the TGS or SWMS?
Do not simply continue and try to make the arrangement work. Raise the issue with the TMI or Supervisor so it can be assessed and the appropriate action taken.
What if there is a problem completing the digital pre-start?
If there is no signal, the app is not working, or there is another genuine problem preventing completion, report it to the appropriate person. The issue can then be addressed rather than leaving the check incomplete or completing it much later.
Is the pre-start just a compliance requirement?
No. While documentation may be checked during audits, the main value of the pre-start is the discussion and risk check it prompts before work begins.
