Abstract

Toowoomba Regional Council (TRC) is proceeding to develop a documented asset management system which includes the use of criticality. Criticality is a rating assigned to an asset based on its consequence of failure. A criticality analysis identifies assets that are fundamental to performance and provides a basis for strategic decision-making. The aim of this dissertation was to provide TRC with the framework required to perform an asset criticality analysis on its water and wastewater asset base.

Criticality assessment criteria were developed in conjunction with TRC’s Enterprise Risk Policy to ensure consequences were assessed against corporate interests. Severity scorecards were established to quantify the impact of the consequences and guidelines were created to ensure consistent application. A model was produced in Microsoft Excel to process data and automate criticality calculations.

The methodology and model were applied to a total of 1210 assets which varied in size, cost, location and function. The resulting asset criticality ratings were realistic and provided an accurate representation of their relative importance. In total, the criticality ratings indicated that 23.64 percent were non-critical, 73.55 percent were partially critical, 2.73 percent were critical and 0.083 percent were extremely critical.

The results indicated that the criticality framework was suitable for use by TRC and would provide a comprehensive foundation to standardise decision-making, identify critical assets and prioritise asset management activities to optimise the distribution of funds and resources.
