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

4. Lifecycle Management Plan
4.1    Assets
Council’s bridges play a vital role in connectivity of the 680km road network (both sealed and
unsealed roads) across the Noosa Shire. There is a total of 56 structures that are made up of
concrete and timber bridges as well as concrete pedestrian underpasses that are considered in this
Asset Management Plan (AMP). A detailed register of these assets is located at Annex B.

The 56 structures include:
• 23 x Timber road bridges
• 28 x concrete road bridges
• 5 x concrete underpasses




4.2    Asset Valuation
The value of the Bridge Assets, at the end of the financial year 2016/2017 for the purposes of this
AMP is summarised below.

        May 2018            Current Asset Cost     Current Depreciation      Written Down Value

 Road Bridges                $103,604,223           $ 25,168,425            $78,435,798

4.3    Asset Condition
Levels of service and asset management decision making is directly linked to asset condition; this
determines what condition the asset should be in before an asset management intervention. The
intent of current and future Condition Assessments (CA) is to:
•     Provide a robust and repeatable process for carrying out condition assessments on Council’s
      bridge assets;
•     Use condition assessments to develop programs for intervention with regards to further
      inspection, monitoring, maintenance and renewals;
•     Provide a basis for information for the modelling of condition data for the likelihood of asset
      failure for those assets not inspected.

A consistent condition ranking scale has been chosen by Council as the framework for measuring
bridge assets, based on the 1 to 5 ranking according to the International Infrastructure Management
Manual (IIMM). Any asset scoring 4 (fair) to 5 (poor) will be considered under a renewal program.
