Summary: Timber utility poles form key infrastructure in Australian power distribution network with an estimated 1.75 billion dollars to be invested for their maintenance and replacement in the next 10 years. Lack of reliable Non-Destructive Evaluation (NDE) tools for evaluation of their condition and strength results in waste of valuable resources by replacing healthy serviceable poles and jeopardises safety and reliability of power distribution systems by overlooking faulty poles. This project aims to develop a novel wave-based cost-effective NDE tool for asset management of timber utility poles.
