Project Arborist Services Penrith
AQF Level 5 Consulting Arborists, Construction Monitoring, Tree Protection and Compliance Certification
Need a Project Arborist for your development in Penrith?
Penrith Tree Permit Services provides AQF Level 5 Project Arborist services throughout the Penrith Local Government Area, helping builders, developers, architects, engineers, Principal Certifiers and project managers manage retained trees and arboricultural compliance during construction.
Where Development Consent requires tree protection, inspections, excavation supervision or arboricultural certification, we review the approved documentation and establish what needs to occur before, during and at completion of construction.
Wherever practicable, the same AQF Level 5 Consulting Arborist who prepares the Development Arborist Report or Arboricultural Impact Assessment continues as the nominated Project Arborist, providing continuity from planning through to final compliance.
Whether the project is a new home, duplex, subdivision, childcare centre, commercial development, warehouse or infrastructure project, our role is to help protect retained trees while supporting compliant construction.

What Does a Project Arborist Do?
A Project Arborist manages the arboricultural requirements for retained trees during demolition and construction where required by the Development Consent and approved documentation.
Depending on the project, this can include:
- Reviewing arboricultural consent conditions and approved documentation
- Establishing and inspecting tree protection measures before construction begins, including fencing, exclusion areas and ground protection
- Monitoring Tree Protection Zones and supervising excavation near retained trees
- Investigating roots where site conditions differ from what was anticipated
- Assessing construction changes near retained trees
- Advising builders and contractors and attending site meetings
- Preparing construction-stage compliance reports
- Providing arboricultural compliance certification where required by Development Consent
A Project Arborist may be required wherever Development Consent conditions call for ongoing arboricultural supervision, inspections or compliance reporting. This varies by development rather than being the same for every project.
On some Penrith developments, Development Consent conditions specifically require an AQF Level 5 Project Arborist to remain engaged for the duration of demolition and construction works.
We review the relevant arboricultural conditions and approved documentation first to establish the actual inspection, monitoring and reporting program the project needs.

Review Development Consent
We review the Development Consent conditions, approved Arborist Report or AIA, Tree Protection Plan where applicable, and other relevant project documentation to establish what arboricultural requirements apply.
Establish tree protection
Before relevant construction work begins, required tree protection measures are established and inspected.
Monitor construction
Inspections are undertaken at the stages required by the Development Consent, or wherever construction activity such as excavation, service installation, demolition or access changes may affect retained trees or Tree Protection Zones.
Investigate where required
Where construction encounters roots or site conditions differ from those anticipated, further arboricultural assessment may be required. Non-destructive root investigation can help establish root location, diameter and depth to inform construction decisions.
Report and certify
Site observations and arboricultural decisions are documented. Where required by Development Consent, construction-stage compliance reports and final arboricultural certification can be prepared within the scope of the Project Arborist requirements.
This is arboricultural compliance documentation and does not mean the Project Arborist issues the Occupation Certificate.
Tree Protection During Construction
Construction activities can damage retained trees before visible symptoms become apparent.
Penrith City Council’s Development Control Plan Part C2, Vegetation Management, includes construction-stage protection requirements for retained trees. Protected areas are to be managed to avoid damaging activities such as inappropriate vehicle or machinery access and stockpiling of construction materials.
Where a Tree Protection Plan forms part of the approved development documentation, its specified measures also need to be implemented and maintained.
Construction can affect retained trees through:
The Project Arborist’s role is not simply to inspect fencing. It is to assess proposed construction activity against the approved documentation and advise on the appropriate way forward where retained trees may be affected.
Where root location is uncertain, further investigation may be appropriate before excavation proceeds.
Penrith City Council’s adopted Development Control Plan references AS 4970-2009, Protection of Trees on Development Sites. Arboricultural documentation should also have regard to the current applicable Australian Standard together with Council requirements and the approved development documentation. The specific requirements for an individual development remain determined by its Development Consent and approved plans and reports.
Council information last verified: 30 August 2026. Council requirements can change. This page provides general guidance current as of the date above. For a determination specific to your property, confirm current requirements with Penrith City Council or arrange a site assessment.
Development Projects We Support
Residential Development
New homes, duplexes, multi-dwelling developments and residential subdivisions where retained trees require protection or construction-stage arboricultural supervision.
Commercial & Industrial Development
Commercial buildings, warehouses, industrial facilities and mixed-use developments involving retained trees, construction impacts or arboricultural consent conditions.
Community & Infrastructure Projects
Schools, childcare centres, community facilities, road upgrades and infrastructure projects requiring construction-stage tree protection and monitoring.
Rural & Growth-Area Development
Rural development, larger sites, rezoning-related projects and growth-area development where retained trees, native vegetation, biodiversity or other site constraints may interact with construction.
We work with architects, builders, developers, engineers, Principal Certifiers, town planners, landscape architects, surveyors, utility contractors and project managers to integrate arboricultural requirements into the construction process.
Where a potential tree conflict arises, early communication can help identify an appropriate response before work proceeds.
Project Arborist Services Throughout the Penrith LGA
AQF Level 5 Project Arborist services are available throughout Penrith’s North, South and East Wards for residential, commercial, industrial, community, infrastructure, rural and growth-area developments.
Project Arborist matters can involve retained trees close to new construction, excavation within Tree Protection Zones, root conflicts, service installation and construction-stage compliance.
Relevant Penrith Project Arborist Case Studies
Real construction projects provide useful examples of how Development Consent conditions, Tree Protection Zones, roots and changes during construction can affect retained trees and compliance requirements.
Our Project Arborist case studies cover relevant matters such as:
- Pre-construction tree protection and Tree Protection Zone inspections
- Excavation monitoring and root investigation during construction
- Changes to proposed work near Tree Protection Zones
- Tree protection compliance issues
- Development Consent compliance
- Final arboricultural reporting and certification

Penrith Development Tree Compliance GuideFrequently Asked Questions
When development consent requires a Project Arborist, and what the role involves.
Does every Penrith development need a Project Arborist?
No.
The requirement depends on the Development Consent conditions and approved arboricultural documentation for the particular development. Some Penrith Development Consents specifically require an AQF Level 5 Project Arborist to remain engaged during demolition and construction.
Can the same arborist prepare the AIA and supervise construction?
Yes.
Wherever practicable, the same AQF Level 5 Consulting Arborist who prepares the Development Arborist Report or Arboricultural Impact Assessment continues as the Project Arborist, providing continuity between the original tree assessment, approved recommendations and construction-stage decisions.
Do I need a Project Arborist for the entire construction period?
It depends on the Development Consent.
Some approvals require the Project Arborist to remain engaged throughout demolition and construction, while others require inspections or supervision at particular stages. We review the Development Consent and identify the required program.
What happens if roots are found during excavation?
Work near the roots may need to pause for assessment.
The Project Arborist can inspect the roots and surrounding works, document the findings and provide arboricultural advice consistent with the approved development requirements. Where root location is uncertain before excavation, non-destructive root investigation may be appropriate.
Can you provide compliance certification?
Yes, where required within the scope of the Development Consent.
We prepare arboricultural compliance reports and certification relating to tree-protection and Project Arborist requirements. This is arboricultural compliance documentation, not the Occupation Certificate itself.
