Case study 2.11

Invercargill City Council – Being clear about the maintenance strategy means being clear about the best mix of planned and reactive work, and what performance standards contractors need to work to

Invercargill City Council has developed maintenance and operations plans for its major assets – roading and water supply. These are detailed for each class of asset. The maintenance approach is clearly influenced by the criticality of the various assets (for example, setting operating pressure for bulk supply pipes).

As part of setting out its management strategies, the Council is explicit about performance criteria, and considers trade-offs between planned and unplanned maintenance. For example, its roading asset management plan identifies the rationale and its approach to differentiating between planned and unplanned maintenance for each of the asset classes.
