Tree Management
Decay detection, aerially or from ground level
Applying the Resistograph® PD-500 or 400 series to test wood for structural weaknesses
Platform for large sized tree structural testing
Advanced testing using decay detection instruments Picus-3® Sonic Tomography and Resistograph® PD-500 at multiple levels on the tree
Sonic tomography
The Picus-3 measures sound velocity between sensor points installed on the tree and presents results of decay and hollows in 2D & 3D imaging for analysis
Visual Tree Assessment (VTA)
VTA is the most common form of tree assessment in urban areas. Our Arborists use their knowledge and experience to condition survey or risk assess, using the latest GIS/GPS technology
Root Exploratory Trenching (RET)
RET may be required to determine the quantity and sizes of tree roots present and the impact of permanent or temporary works proposed adjacent to tree(s). Methods of RET such as careful excavation by hand tools or, preferably use of specialised pneumatic tools are typically used so as not to damage tree roots. Our arborists provide RET method design, supervisions and construction impact assessment reporting
LiDAR scanning for advanced assessments such as tree branch integration with proposed structure
LiDAR – ‘Point Cloud Scanning’ provides our assessors with sub-decimetre accuracy of tree trunks, branches and stems for overlay to Dwg files for in-depth studies
LiDAR scan of highway, with oversized transport structure superimposed
LiDAR scanning has multiple useful functions including in this case, clash detection for our assessors to calculate the impacted tree volumes
LiDAR scan of highway – plan view
Scan image of study area. Production of fly-through’s are also available and a useful visual tool for client presentations and the like
TREE MAINTENANCE – Tree maintenance feasibility study
Graphical representation of feasibility study for maintenance of trees located indoor / confined spaces
Tree Risk Assessment
Our Qualified Tree Risk Assessors use their skills, knowledge and advanced GIS/GPS systems and software for identification and rating of tree risk, including prescribing mitigation measures and prioritizing the mitigation work
