Tree Contractor Checklist for Councils & Project Managers

Tree works carry public safety, access, environmental and reputational risk. For councils, Tier-1 contractors and facility managers, choosing a tree service provider should never come down to price alone.

A strong tree contractor checklist helps procurement teams compare contractors against the same evidence. It gives project managers a clear way to review licences, insurances, SWMS, equipment, emergency capacity, recycling practices and reporting standards before work starts.

SafeWork NSW has recorded serious tree work incidents involving falls from height and workers being struck by falling objects during pruning and removal works. For councils and asset owners, this makes contractor selection a risk control step, not just a buying task.

Plateau Trees works across residential, commercial and government tree services, with arborist reports, pruning, removals, stump grinding, emergency response and land clearing across Sydney and nearby regions.

For urgent tree hazards, keep the 24/7 emergency line visible in your project notes and escalation plan.

Key Takeaways

• Use a tree contractor checklist before shortlisting suppliers, not after the tender closes.
• Ask for proof of insurance, licences, certifications, SWMS, plant registers and incident records.
• Score safety systems, response capacity, environmental handling and reporting evidence separately.
• Check that the contractor can handle after-hours make-safe work, traffic controls and multi-site programs.
• Invite Plateau Trees to respond where the works call for Sydney-based crews, audit-ready systems and 24/7 emergency coverage.

Core qualifications, insurances and certifications to check

A contractor may look suitable on a rate card, yet still be weak on evidence. Your tender pack should ask for current documents, expiry dates and named accountabilities.

For public works, the contractor should be able to explain how its systems meet site, council and contract requirements. If your tender relates to public land, roadside works, parks, schools or high-use community assets, link the scope back to the government sector requirements that apply to public-facing tree works.

Start with required business evidence

Ask each contractor to provide:

• ABN and business registration details
• Public liability insurance
• Workers compensation insurance
• Professional indemnity cover, where reports or advice form part of the scope
• Motor vehicle and plant insurance
• Current licences or competency records for high-risk tasks
• Subcontractor management process
• Evidence of quality, safety and environmental systems

NSW Government procurement guidance tells buyers to give suppliers clear evaluation criteria, so tenderers know how their response will be assessed. This also helps internal reviewers compare responses with less room for subjective scoring.

Check arborist skills by task

Tree work is a wide category. SafeWork NSW describes tree work as including lopping, pruning, trimming, repairing, maintaining, transplanting and removing trees.

Match qualifications to the task:

• Tree risk assessment
• Arborist reports
• Tree pruning near roads, schools, hospitals or public paths
• Tree removal in constrained areas
• Works near overhead powerlines
• Stump grinding
• Wood chipping
• Land clearing
• Emergency make-safe works after storms

If the works begin with inspections, asset condition reviews or hazard ratings, ask how the contractor handles a tree risk assessment in Sydney and how that assessment is turned into a staged work plan.

For council tree contract requirements, ask whether the same team preparing the method can brief the crew, record the works and close out the job with evidence.

Safety systems, SWMS and incident history

Tree works may involve chainsaws, elevated work platforms, cranes, ropes, falling limbs, traffic, pedestrians, live services and unstable ground. A safe contractor should be able to show how those risks are identified, controlled and reviewed.

SWMS and site controls

Ask for sample SWMS covering:

• Tree pruning
• Tree removal
• Working at height
• EWP use
• Crane-assisted removal
• Wood chipping
• Stump grinding
• Working near roads and pedestrians
• Working near overhead power lines
• Emergency storm response

Safe Work Australia’s tree work guide covers duties, WHS risk management, hazards and control measures for tree trimming and removal work, including pruning, amenity tree removal, wood chipping, stump grinding and root pruning.

A strong SWMS should name the hazard, control, responsible person and review step. It should be site-specific, not a generic form with no link to the work area.

Incident history and safety culture

Ask for:

• Lost time injury history
• Notifiable incidents over the past three years
• Corrective actions from incidents
• Toolbox meeting records
• Supervisor inspection records
• Training matrix
• Plant maintenance logs
• Emergency response process

A contractor with incidents in its history should not be ruled out automatically. The key question is whether the contractor can show corrective action, better controls and stronger supervision.

SafeWork NSW’s tree work self-assessment checklist includes checks for visual tree assessment, site-specific hazards, ground conditions, weather, powerlines, traffic, insects, slips, trips and drop zones before work starts.

Use that as a practical benchmark when writing arborist tender questions.

Environmental practices and recycling

Councils and facility managers are under pressure to reduce waste, protect habitat and show better environmental reporting. Tree contractors should explain where green waste goes, how timber is separated and how habitat features are managed.

For tenders with sustainability, landfill reduction or ESG reporting requirements, include a specific question about green waste tree recycling. Ask how waste is recorded, reused, transported and reported after pruning, removals and land clearing.

Ask how green waste is handled

Your checklist should ask:

• Is green waste chipped, mulched, hauled or reused?
• Can waste streams be reported by volume or load?
• Are logs, mulch and contaminated material separated?
• How are weeds or pest-affected materials handled?
• What happens to habitat hollows where ecological value is present?
• Can the contractor provide waste transfer records?
• Is site restoration included after land clearing?

The NSW EPA states that organic waste in landfill releases methane, a greenhouse gas. The EPA also states that landfill methane can make up a large share of local government direct and indirect greenhouse gas contributions.

For councils, that makes recycling evidence more than a sustainability line. It can support reporting, procurement scoring and community outcomes.

Program delivery – crews, equipment, coverage

A contractor can have strong paperwork and still fail on delivery. Councils and project managers need to know who will arrive, when they will arrive, what equipment they will bring and how works will be staged.

For hospitals, campuses, shopping centres, industrial sites, business parks and infrastructure projects, the same checklist can be adapted for the commercial sector, where disruption, tenant access, safety zones and site presentation often carry extra weight.

Review crew capacity

Ask tenderers to list:

• Number of qualified arborists
• Number of field crews
• Supervisor structure
• After-hours crew access
• Plant and equipment list
• Backup equipment
• Traffic control partners
• Subcontractor use
• Regional coverage
• Response times for urgent works

For ongoing contracts, ask whether the contractor can plan and report multi site tree maintenance programs across several locations. This is useful for councils, strata portfolios, commercial property groups and infrastructure contractors managing spread-out assets.

Coverage and emergency response

Your tree contractor checklist should keep emergency response near the top. This is vital for storms, failed limbs, blocked roads, school sites, public paths and asset damage.

Ask:

• Is 24/7 response available?
• Who answers after-hours calls?
• What triage details are recorded?
• Can photos be submitted before dispatch?
• What is the make-safe process?
• Are crews available from Sydney through to the Central Coast?
• How is the site handed back after the first response?

A clear emergency process should show how hazards are triaged, who is contacted, what controls are used and how follow-up works are scheduled after the immediate risk is made safe.
