The last fortnight before Christmas is the fastest-moving time of the year on most sites, and the shutdown itself is often an afterthought: tools in the van, gate chained, see you in January. A site that is locked and left for three weeks is still a workplace, and the weeks after the break are when half-remembered isolations and unchecked scaffolds cause trouble. Here is a checklist for closing the site properly and reopening it safely.
A site does not stop being a workplace when the crew goes home. The duty to secure it and to keep other people safe from it continues for every day of the break, and the duty to make sure it is safe to work on again applies the morning the crew returns. Plan both ends: the shutdown walk-through before the last worker leaves, and the restart inspections before the first one picks up a tool.
Section 19 of the WHS Act, the primary duty of care, requires a PCBU to ensure, so far as is reasonably practicable, the health and safety of workers – and that other people are not put at risk by the work. Over a shutdown the “other people” part does the heavy lifting: neighbours, passers-by, and anyone who climbs the fence.
Regulation 298 of the model WHS Regulations makes that specific for construction. A person with management or control of a workplace where construction work is carried out must ensure, so far as is reasonably practicable, that it is secured from unauthorised access. In deciding what that takes, you look at the risks from unauthorised access, how likely it is – a site next to a school, a park or shops is more likely to be entered than one in a quiet factory precinct – and, where access cannot be prevented, how to isolate the hazards within the site.
Regulation 308 adds the signage: on a construction project, the principal contractor must put up signs showing their name and contact details, including a number for out-of-hours contact. Over Christmas that number is the one a neighbour calls when a fence panel is down or water is pouring off the slab, so it needs to reach a person who will answer.
For scaffold, good practice is clear: prevent unauthorised access while it is incomplete or unattended, and have a competent person inspect it before work resumes after a break.
The checklist is only worth anything if someone walks the site against it after the last subcontractor has packed up, not before. Nominate the person – usually the site supervisor – and have them do it with the written checklist in hand, ticking each item and noting anything left undone and why. Take dated photos of the fence line, the gates, the isolations and the covered excavations. Keep the signed checklist and the photos with the site records. If anything is questioned over the break, that record is the evidence of what the site looked like when you left it.
Nobody starts work on the first morning back until the site has been inspected. Scaffold is checked by a competent person before anyone goes on it. Excavations are inspected for water, collapse and softened ground before re-entry. Every item of plant gets its pre-start check, and anything that sat in the weather for three weeks gets a closer look. Temporary electrical is inspected before it is re-energised, with the shutdown isolation list used as the checklist in reverse.
Then the paperwork. Review the SWMS for anything that changed over the break – new subcontractors, a different crew, a changed site layout, weather damage – using our guide on when a SWMS must be reviewed or updated. Re-issue any permits rather than reusing December’s; a permit is tied to a time window and conditions that no longer exist, as explained in permit to work vs SWMS. Finish with a first-day-back toolbox talk that covers what was inspected, what changed, who is new, and the plan for the week.
Most shutdown problems are created in the fortnight before it, when the program says finish by Friday and the crew is tired. Long hours and the pressure to hand over are a fatigue risk in their own right, and they are also when controls get skipped: the edge protection that comes down early, the trench nobody covers because the backfill is coming Monday. The deadline does not change the duty. If a control is in the SWMS, it stays in place until the job it protects is finished, and the shutdown walk-through is the last check that nothing was traded for time.
Do I have to secure a site over the Christmas shutdown?
Yes. Under regulation 298 the person with management or control of a construction workplace
must ensure, so far as is reasonably practicable, that it is secured from unauthorised access,
and the duty does not pause for the break. What is reasonably practicable depends on the risks
on the site and how likely people are to get in.
Does scaffolding need inspecting before work restarts?
As a matter of good practice, yes: a competent person should inspect the scaffold before work
resumes after a break. Three weeks of wind, rain and possibly uninvited visitors is exactly
the situation that practice is for.
Do I need a new SWMS after the shutdown?
Not automatically. You need to review it: if the work, the crew, the site conditions or the
controls have changed over the break, the SWMS is revised and signed again before that work
starts. If nothing has changed, the review confirms that and the existing SWMS stands.
Who is responsible for site security when there are subcontractors?
The person with management or control of the workplace – usually the principal
contractor or builder – holds the regulation 298 duty to secure the site. That does not
take the subcontractors out of the picture: every PCBU on the job shares the section 19 duty
for the work it does, including leaving its own plant, materials and work areas safe when it
packs up.
