Preguntas frecuentes (FAQ)
What is ITEG?
The Independent Tree Expert Group is an association of tree statics experts who pursue an integrated, holistic approach when conducting tree safety tests.
What are the goals of ITEG?
The goal of Independent Tree Expert Group is to combine visual and technical examination procedures in a standardized way, resulting in an open and integrated approach to tree safety checks and allowing for a comprehensive assessment of trees.
The Independent Tree Expert Group is also a step towards a better qualification of authorised tree experts. Using current methods and procedures for tree safety checks in a proper, standard proceeding, complying with all existing rules, precise expert statements on tree stability can be made.
Special attention is made to the expert group’s results regarding to the tensile test according to WESSOLLY. Thus, the online program Tree Stability Evaluation was developed to calculate trees’ stability and safety against fracture. The measured data from the tensile test according to WESSOLLY (tilting angle, edge fibre strain, edge fibre compression and tensile load) are calculated proportionally to the estimated wind load, resulting in safety statements.
How can I certify as an authorised ITEG expert?
An expert seminar is planned to qualify ITEG members. It shall provide qualified persons with an intensive training on the job as an authorised expert of tree care and tree statics. In several course modules the participants focus on the variety of tasks of an authorised expert. In addition to legal facts, subject-specific information, and current methods of integrated tree safety checks, a particular emphasis will be on how to create expert opinions.
How can I test the TSE calculation program?
The online use of the calculation program requires a registration and currently is only intended to give interested users, when having entered the data required, an idea on the tensile test’s proceeding.
TSE therefore is not suited to carrying out independent assessments of stability and safety against fracture for “real life applications”. Interested tree experts who want to test TSE can register at http://www.die-nuernberger.info.
What are the costs of the participation?
Currently, participation is for free. However, it is intended to charge annual TSE usage fees, combined with compulsory, fee required user trainings.TOP
