Tree risk advanced assessment
Over many years of assessing trees for risk and what hazards they pose to my clients their employees structures, homes etc. many a time the tree warrant an advanced or level 3 assessment this could be an aerial assessment of the scaffold upper branch junctions, damaged along the trunk or the tree assessed may need to have the trunk assessed by a Picus Sonic Tomography to determine the amount of solid timber to decayed or hollow sections unable to be seen visibly and or a soil or tissue test to determine the course of the trees ill health.
On most occasions clients decide not to do these tests as the cost is to high yes there is extra expense for these advanced assessments but what is the cost if you don’t do these test and the trees fails and causes damage or worst kills someone.
Recently I had a client ring me up and asked if I can come an assess a tree that I had assessed 10 months ago and recommended a advanced assessment as this tree had a branch fail damaging a roof of 1 of their buildings and they were lucky that no one was using the path below when the branch failed.
The cost of replacing the damaged roof and then now have to remove the tree loosing valuable shade and then replacing that tree is a far more expensive than hiring an Elevated work platform EWP (cherry picker) and myself for 2 hours when the defect could have been identified the limb removed.
International Society of Arboriculture (ISA) Tree Risk Assessment Qualification (TRAQ) recommends different levels of assessment from a walk/drive by a visible tree assessment and advanced assessment.
When you are a manager/owner of an amenity tree it is your duty to maintain this tree and minimize risk that it poses to you your family, your home or buildings.
To determine the structural integrity of the tree advanced assessments may need to occur, such as an aerial assessment with an Arborist using a Elevated work platform (EWP a.k.a. cherry pickers) or a Picus Sonic tomography, to sound the tree.
For any or more information please contact me by phone, e-mail or leave a message on face book and I will contact you (If you do contact by Facebook please leave a Phone number and best time to call).
