Treework Environmental Practice will be taking Tree Statics and the Static Load Test to Australia and New Zealand in February 2017 for a series of seminars aimed at helping arboricultural professionals make better informed decisions about tree structural stability and likelihood of failure.
The one-day seminars will provide attendees with essential background knowledge in engineering principles and biomechanics; a best-practice approach to assessing tree structural integrity; and an unmissable opportunity to calibrate likelihood of failure estimates with other arborists at the sharp end.
David Evans of the Arbor Centre in Bath will be introducing VALID, a new approach to estimating the likelihood of tree failure, while Treework Environmental Practice consultants Paul Muir and Claire Harbinson will be explaining why looking at tree stability using engineering principles and concepts such as the safety factor is a more robust approach that allows for the more frequent retention of trees than some traditional methods. These engineering principles are enshrined in the static load test, which references load, material properties and the geometry of a tree to generate a safety factor to inform the likelihood of stem breakage and root plate failure. The Static Load Test is also currently the only tool that can reliably assess root anchorage.
Each day will be split between classroom sessions and hands-on, in the field workshops, including a demonstration of the static load test, originally developed by Lothar Wessolly. Paul and Claire are excited to be promoting this approach on behalf of Treework Environmental Practice.
The seminars will take in Auckland, Sydney, Brisbane, Sydney, Melbourne, Adelaide and Perth between 13th and 27th February 2017.
