Our Tree Risk Assessment Services
Comprehensive tree risk evaluation using industry-standard methods
QTRA Risk Assessment
Quantified Tree Risk Assessment methodology that evaluates the likelihood of tree failure, potential impact, and target value to provide numerical risk ratings and prioritised management options.
TRAQ Assessment
Tree Risk Assessment Qualification methodology providing systematic evaluation of tree structure, site conditions and targets to determine risk levels and appropriate mitigation measures.
Post-Storm Risk Assessment
Urgent evaluation of trees following storm events to identify new or increased risks from structural damage, root plate movement or soil saturation requiring immediate attention.
Property Risk Audits
Comprehensive property-wide tree risk audits for commercial properties, strata complexes and public spaces to identify and manage potential hazards through periodic assessment.
Advanced Tree Risk Testing
Specialised assessment techniques including sonic tomography, resistograph testing and root plate evaluation to detect internal decay, structural weaknesses and stability issues.
Risk Mitigation Plans
Detailed action plans with prioritised recommendations for treatment options including pruning requirements, bracing systems or removal where necessary to reduce identified risks.

Our Tree Risk Assessment Process
Systematic evaluation to accurately identify and quantify tree risks
Initial Consultation
We begin with a detailed discussion about your specific concerns, the tree/s to be assessed, site history, and how the area around the tree is used, to determine the scope of the risk assessment required.
Site Inspection
Our qualified arborists conduct a thorough on-site assessment, examining tree structure, signs of defects, surrounding environment, targets, and occupancy rates to gather all data needed for accurate risk calculation.
Specialised Testing
Where necessary, we perform additional diagnostic tests such as resistograph drilling, sonic tomography, or root plate assessment to identify internal defects or decay not visible from external inspection.
Risk Calculation
Using QTRA or TRAQ methodology, we analyse all collected data to calculate risk based on the likelihood of failure, impact potential, and target values, resulting in quantifiable risk ratings.
Report Preparation
We prepare a comprehensive report documenting our findings with photographic evidence, risk calculations, detailed explanations, and prioritised recommendations for risk mitigation.
Mitigation Planning
We develop appropriate risk management strategies which may include monitoring protocols, pruning specifications, installation of support systems, or removal recommendations where necessary.
Tree Risk Assessment FAQs
Professional Tree Risk Assessment Services in Sydney
Sydney Arborist Solutions provides expert tree risk assessment services throughout Sydney, delivered by Level 5 qualified arborists with specific training in QTRA (Quantified Tree Risk Assessment) and TRAQ (Tree Risk Assessment Qualification) methodologies. Our systematic approach evaluates the likelihood of tree failure, potential impact, and target value to provide quantifiable risk ratings and appropriate management recommendations.
Professional tree risk assessments are essential for property owners, strata managers, schools, councils and businesses to fulfil duty of care obligations, support insurance claims, prepare for development applications, and maintain safe environments. Unlike basic tree inspections, our assessments provide quantified risk ratings based on established methodologies recognised worldwide.
Understanding QTRA and TRAQ Methodologies
We utilise industry-leading risk assessment frameworks to provide objective, evidence-based evaluations. The Quantified Tree Risk Assessment (QTRA) system applies established risk management principles to tree assessment, quantifying the risk of significant harm from tree failure in a way that enables site managers to make informed decisions about tree safety management.
The Tree Risk Assessment Qualification (TRAQ) methodology uses a structured, systematic process to evaluate three components: the likelihood of tree failure, the likelihood of that failure impacting a target, and the consequences of the impact. This results in qualitative risk ratings from low to extreme, helping prioritise mitigation measures. Our arborists are qualified to employ either approach based on your specific requirements.
When to Request a Tree Risk Assessment
There are several situations where a professional tree risk assessment is recommended: after severe weather events that may have compromised tree structure; when visible defects such as cracks, decay, or lean are observed; as part of pre-purchase property inspections; for insurance or legal documentation; before commencing construction near trees; or as regular maintenance for properties with mature trees in high-use areas.
Tree risk assessments are particularly important for commercial properties, schools, public spaces, and strata complexes where duty of care obligations are heightened. Regular assessments help identify potential issues before they become serious hazards, allowing for proactive management rather than reactive response to tree failures.
Advanced Diagnostic Techniques for Accurate Risk Assessment
Beyond visual assessment, our arborists utilise specialised diagnostic tools when necessary to provide more accurate evaluations of internal tree conditions. Sonic tomography creates visual maps of internal wood density to detect decay patterns, while resistograph drilling measures wood resistance to identify decay, cavities, and cracks within trunks and major limbs.
We also perform root plate assessments to evaluate stability issues, and conduct detailed crown inspections to assess structural integrity of the upper tree. These advanced techniques allow us to detect hidden defects not visible from ground-level inspection, ensuring our risk ratings accurately reflect the tree's actual condition rather than assumptions based solely on external appearance.
