2018-12-11 S&O Agenda - Attachment 1 to Item 16 - Road Infrastructure Asset Management Plan

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
      road infrastructure 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 likelihood of asset failure
      for those assets not inspected.

A consistent condition ranking scale has been chosen by Council as the framework for measuring
road infrastructure 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 and prioritised
under an asset specific renewal program.

Sealed road condition assessments are undertaken by contracted services due to the volume of
asset data attributes that are collected across the network. The data is loaded into Council’s
Pavement Management System (PMS) and is analysed and modelled to create a reseal program for
the sealed road network. A full network condition assessment is planned every four (4) years to
ensure the continued development and updating of a five-year reseal program is based on up to
date condition information.

In addition to the above contracted condition assessments, Council staff undertake visual condition
assessments for requests that have been reported for sealed road surfaces in poor condition. These
assessments are undertaken on a “reactive” approach to determine if the request warrants a section
of road be prioritised and placed within the reseal program for future renewal.

The gravel re-sheeting program is the asset renewal of the gravel road surfaces. Gravel road
condition assessments are conducted on an annual basis. This annual assessment determines the
gravel road re-sheeting program.




There are a number of different asset classes within the road infrastructure that are yet to have a
physical condition assessment undertaken. For the purpose of this AMP, these assets have been
assigned an age-based condition which is determined on the remaining life of the asset. Further
development and prioritisation is required to ensure that all road infrastructure assets are reconciled
within the asset system and condition assessments are undertaken. When undertaking condition
assessments, the asset attributes will be updated prior to the next roads asset evaluation. The
condition assessments will enable the development of renewal programs for the specific asset
classes listed below:

   •   Kerb and Channel
   •   Carparks
   •   Roundabouts
