The risk of extreme weather is a regular theme across large utility networks. Thr JBA Group have brought new technology and efficiencies for the managemnt of large-scale scour, erosion, flood and earthwork examinations which are ideally suited for Australian conditions.
Using tools such as GISmapp, these have allowed us to undertake network-wide risk assessments, including:
8,000 above-ground assets
616 sub-stations and 1378 primary grid sites
300 water facilities
150 coastal defence assets
Recent inspections have included the stability of an electricity pylon that was placed at risk following significant bank erosion. Our team undertook a geomorphological assessment to advise on the best approach to either protecting or relocating the pylon. This involved a site based assessment, hydraulic modelling, impact assessment and engineering appraisal. A combined apprach of partial relocation, bank protection and armour stabilisation was agreed, and the risk removed from the pylon.
