Site-Specific Safety Plans are a familiar part of construction projects across New Zealand.
If you’re the main contractor, you may need an SSSP to demonstrate to the client or their representative how health and safety will be managed throughout the project.
If you’re a subcontractor, you may be asked to provide an SSSP or equivalent project-specific information showing how you’ll safely manage your particular scope of work.
Either way, the purpose should be more than getting a document approved before work starts.
A good SSSP should translate your broader health and safety arrangements into the reality of a specific project. It should give the project team clarity around some fundamental questions:
- What are we doing?
- Where could serious harm occur?
- What controls are we relying on?
- Who is responsible?
- Where do we need to coordinate with others?
- How will we know those controls are working?
Answer those questions well and the SSSP becomes more than paperwork. It becomes a practical project management tool.
What is a Site-Specific Safety Plan?
A Site-Specific Safety Plan (SSSP) sets out how health and safety will be managed for a particular project, site or scope of work.
It shouldn’t simply repeat an organisation’s entire health and safety management system. Instead, it should take the relevant requirements from that system and apply them to the actual project.
For a main contractor, that may include demonstrating to the client or client representative how health and safety will be planned, coordinated, monitored and reviewed across the project.
For a subcontractor, it may demonstrate how its particular activities, workers, plant, risks and controls will be managed and coordinated with the wider project.
The format and level of detail will vary depending on the size, complexity and risks involved. What matters is that the plan reflects the work that is actually going to happen.
What should an SSSP contain?
A practical SSSP will commonly address:
- Project and scope information — what is being undertaken, work stages, duration and relevant site conditions.
- Roles and responsibilities — who is responsible for management, supervision, coordination and key health and safety activities.
- Critical risks and high-energy hazards — where the potential for serious harm sits on this project.
- Controls — what will prevent or minimise serious harm and who is responsible for implementing them.
- Site arrangements — access, security, deliveries, traffic, plant, pedestrian movement and public interfaces.
- Worker engagement — inductions, pre-starts, toolbox discussions and how workers raise health and safety matters.
- Contractor management and coordination — how different PCBUs and work activities will interact.
- Training and competency — what competencies are required and how they will be verified.
- Emergency arrangements — first aid, evacuation and project-specific emergency or rescue arrangements.
- Monitoring and review — how the project and its important controls will be checked as the work progresses.
Length isn’t the measure of quality. A useful SSSP provides clarity about how the project will actually be managed.
Start with this project, not the last one
One of the easiest traps is creating a site-specific plan that isn’t particularly site specific. A previous project’s name gets changed. The address gets updated. A few new names are inserted. The rest stays largely the same.
The better starting point is to understand the project in front of you. Ask:
- What work will be happening?
- What will be happening at the same time?
- What plant and equipment will be used?
- Where will people and vehicles interact?
- What other contractors will influence the work?
- Could the public, tenants, clients or neighbouring businesses be affected?
- What changes as the project moves through different stages?
A simple test is to hand the SSSP to the person responsible for running the project and ask:
“Does this help you understand how we’re going to manage this job safely?”
If it doesn’t, the plan probably needs another look.
Focus on critical risks and high-energy hazards
This is where an SSSP can provide significantly more value than a generic hazard register.
The changes to New Zealand’s Health and Safety at Work Act taking effect from 1 April 2027 place greater emphasis on the identification and prioritisation of critical risks.
For a construction project, that makes a simple question increasingly important: what could happen here that has the potential to cause serious harm?
The answer should influence where the project puts its attention.
For construction businesses, the CHASNZ Energy Based Safety approach provides another useful lens. High-energy hazards are associated with the types of events that can lead to serious injuries and fatalities. Depending on the project, these could include exposure associated with:
- falls from height;
- mobile plant and vehicles;
- suspended loads and lifting;
- excavations;
- electricity;
- moving machinery;
- stored or pressurised energy;
- fire and explosion; and
- other significant energy sources.
Critical risk and high-energy hazard aren’t necessarily interchangeable terms. The important point for the SSSP is to use both concepts to help the project understand where serious-harm exposure sits and what needs the greatest attention.
From hazards to the controls that matter
Identifying the risk isn’t enough. The next question is: what are we relying on to prevent the serious event?
Consider mobile plant and pedestrians. Simply writing:
“Mobile plant — high risk. Workers to maintain awareness and wear high-visibility clothing.”
doesn’t provide much confidence.
A better conversation asks:
- Can people and plant be physically separated?
- Can vehicle routes be designed differently?
- Can access to the high-energy area be prevented?
- What happens if someone makes a mistake?
CHASNZ’s Energy Based Safety approach places particular emphasis on Direct Controls — controls specifically targeted at the high-energy source that remain effective even when human error occurs. Where Direct Controls aren’t feasible, other controls may be needed to reduce exposure and the likelihood of error.
For each significant critical risk or high-energy exposure, the project should therefore be clear about:
RISK
What serious event are we trying to prevent?
↓
EXPOSURE
Who could be exposed and how?
↓
CONTROL
What are we relying on to prevent serious harm?
↓
RESPONSIBILITY
Who makes sure the control is established and maintained?
↓
VERIFICATION
How will we know it’s actually working?
That creates a much clearer connection between the SSSP and the work happening on site.
Coordination matters
Construction projects rarely involve one business working alone. Clients, main contractors, subcontractors, designers, suppliers and other PCBUs can all influence how work is carried out.
Where duties overlap, PCBUs need to consult, cooperate and coordinate activities, so far as is reasonably practicable.
An SSSP can help translate that into practical arrangements. This could include coordination around:
- work sequencing;
- shared work areas;
- lifting operations;
- temporary works;
- isolations;
- exclusion zones;
- site access and traffic;
- emergency arrangements; and
- changes affecting other contractors.
For the main contractor, this helps provide clarity across the project. For subcontractors, it helps identify where managing their own work depends on coordination with others.
What happens when the project changes?
Construction doesn’t remain static. Programmes change. Plant is substituted. Vehicle routes move. Excavations deepen. Scaffolding is altered. Work gets resequenced. Different contractors enter the same area.
The SSSP therefore shouldn’t become frozen on the day it is approved. When something changes, ask:
- Has this changed our critical risks or high-energy exposure?
- Are the existing controls still appropriate?
- Who needs to know?
- What needs to change before work continues?
A practical process is: Plan → Change → Reassess → Communicate → Verify.
The plan stays connected to the project rather than becoming a document sitting in a folder.
From the plan to confidence
An SSSP tells you what should happen. Implementation tells you whether it is happening. Verification asks whether the important controls are actually present and effective.
Consider a project where physical separation between pedestrians and mobile plant is identified as an important control. The plan might describe it. The site layout might show it. Barriers might even be installed.
But verification asks another question: does the separation actually work?
- Are people bypassing it?
- Do delivery drivers understand the arrangement?
- Does it still work as the site changes?
- Are there locations where people and plant are still interacting?
That’s much more useful than simply knowing the SSSP was approved.
The process becomes:
- Plan — what should happen?
- Implement — is it happening?
- Verify — are the controls that matter actually working?
- Assure — do we have enough evidence to be confident?
Five questions to ask about your SSSP
Whether you’re the main contractor managing the overall project or a subcontractor managing a particular scope, ask:
- Does our SSSP genuinely reflect this project and the work being undertaken?
- Have we clearly identified our critical risks and relevant high-energy hazards?
- What controls are we relying on to prevent serious harm?
- Are responsibilities and interfaces with other PCBUs clear?
- How are we verifying that the controls that matter are actually working?
Those five questions provide a much clearer picture of the strength of the plan than page count alone.
Know what’s planned. Know what matters. Know it’s working.
A good Site-Specific Safety Plan shouldn’t simply help you satisfy a client requirement or gain access to site. It should provide clarity about how health and safety will be managed throughout the project.
It should help the people doing the work understand where serious exposure sits and what controls they’re relying on. And it should give project leaders greater confidence that what’s been planned is actually happening.
TruSafe supports businesses with the development and independent review of project-specific health and safety arrangements. And where greater assurance is required, TruSafe Verify looks beyond the plan to independently verify whether the controls that matter are actually present and working in practice.
Because a good plan shouldn’t just tell you what should happen. It should help you know what matters — and give you confidence that it’s working.
