We surveyed 57 Grid & Primary substations as part of a FY17 maintenance program. From each of these surveys we then produced a report documenting the condition of the buildings at each of the substations, these reports included a dilapidation score for various stipulated building elements.
We were then able to use this information and compare it with previously completed surveys we had carried out using the same method. This allowed us to create a dilapidation score to measure the rate of deterioration, cross referencing this information with other geographical and socio-economical data we can extrapolate when we expect building failure to occur.
This information can be used to prioritise outstanding maintenance tasks.
