2018-08-07 S&O Agenda - Att 1 to Item 1 - Draft Bridges Asset Management Plan

4.5    Bridge Maintenance Plan
Maintenance is fundamental for the ongoing management of the bridges. It is considered an
investment rather than a liability. The bridges rely on maintenance costs as these are a significant
annual investment that directly influence the potential for a bridge asset to reach its intended useful
life. The ongoing development of asset knowledge through asset inspections, improved maintenance
inspections and activities, subsequent defect monitoring and repairs are fundamental in developing
sustainable intervention levels for renewal and replacement of bridge assets.

Figure 3: Annual Maintenance Costs by Asset Group

Ongoing maintenance costs are identified to ensure council understands the whole of life costs
associated with the day-to-day management of bridges. The figure below identifies the long term
financial commitment required in maintaining assets. In order to maintain assets to an acceptable
level, the cumulative costs over a ten-year period will equate to $23m. It is proposed to develop a
more detailed list of maintenance activities per annum, by bridge assets, through the utilisation of
the T1 asset management system. Annex C highlights the budget for 2018/19 Maintenance.
However, more detail and longer term planning for maintenance has been identified as an
improvement from this AMP.
