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

1. Executive Summary
Noosa Council is responsible for a diverse and extensive range of community assets which
represents a major investment over many years. To fulfil its objectives in delivering a variety of
services to the community, Council must ensure that the assets supporting these services are
managed in a way that guarantees an optimal balance of cost, risk and performance.

Council’s road bridges play a vital role in connectivity of the 867km road network (both 670km sealed
and 197km unsealed roads) across the Noosa Shire. There are a total of 51 Road Bridges and 5
Underpass pedestrian bridges on Council’s asset register, considered in this Asset Management
Plan (AMP). These bridges have a current replacement value of $103m, which equates to 10% of
Council’s financial assets.

The operational and maintenance expenses for road bridges make up approximately 3% of the $70m
annual budget. The capital works program fluctuates from year to year, however, the proposed
2018/19 capital works program with the capital investment of $2.53m for road bridges equates to 9%
of the $28.5m capital works program.

The mitigation of risks is fundamental in the management of bridge structures. For Council to make
informed decisions, with the focus placed on consistent cyclical inspections across all bridge assets.
The condition data needs to be accurately recorded in the asset management system (Technology
One). Bridge data was established by reconciling financial asset data, GIS data and inspection data
to achieve a “single point of truth” for all bridge assets.

Good maintenance and renewal practices have been established, with regular inspections and
subsequent Condition Assessments (CA) across the network of road bridges. There are three levels
of inspections undertaken and they are in accordance with the Department of Transport and Main
Roads Structures Inspection Manual September 2016. Future condition assessments will also
capture a breakdown of assets and comprehensive condition information against bridge components
and will also include the estimated economic life, asset condition, repair priorities, expected year of
replacement and asset values for loading into the asset management system.

This Road Bridge AMP meets the objectives of the Noosa Corporate Plan. Key focus areas under
Theme 4 (Long term planning for Noosa Shire) of the Corporate Plan includes: to undertake long
term financial sustainability planning identifying asset management outcomes and establish
functional Asset Management Plans for all Council asset classes. These focus areas have been a
major driver in the development of this AMP.

The road bridges AMP provides the relevant information and organisational activities to ensure the
organisational objectives for asset management have been achieved and that the pathway for
continual improvement across all management activities for road bridges has been established. The
provision of road bridges is, therefore, a significant part of the infrastructure services provided by
Council.
