Clear results were showing the cross-section of decay present in a tree removed from the car park of a soon-to-open children’s home in Westbury in the grounds of the former Chalford House Hotel. This was all confirmed in the PICUS report. As you can see, the tree looked perfectly healthy from the outside but had to be taken down as it was unsafe, especially over a car park. And we needed to wait until the birds had finished nesting to undertake the work.
Well done by all involved; the new spider MEWP proving its worth, along with the timber crane o remove the timber; no heavy lifting at CC Ltd!
We had to dismantle this veteran beech tree in December, following a survey using a Picus test…
The tree, Fagus sylvatica purperea, had a diameter 2150mm, an 8m circumference and was 18m tall
We used Picus Sonic Tomograph technology; this is a specialised electronic instrument which can ‘look’ internally into a branch or tree trunk and display a computer-generated image of its condition. It achieves this by measuring the speed that sound travels through the wood in a number of different positions and directions. Sound travels fastest through solid wood. Decayed wood will slow its path. By measuring the speed that sound takes to pass through a tree, an idea of its condition can be obtained. In this case, the Tomograph showed a central cavity surrounded by advanced and early decay and the report’s conclusion was to fell the tree as soon as practically possible, and for the work to be carried out by a fully-qualified and insured tree surgeon to BS3998 (tree work) which of course we are!
You’ll see from the pictures below that there is very little viable timber at the base. What there was, was cut up for the client’s use.
