2018-04-10 S&O Agenda - Attachment 1 to Item 6 - Sand Recycling System Asset Management Plan

A consistent condition ranking scale has been chosen by Council as the framework for measuring
SRS assets, based on 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.

A condition assessment was completed on the SRS during in December 2017. The condition
assessment covered all SRS equipment above the high water mark and provided comprehensive
condition information for all plant and equipment. The assessment included estimated economic life,
asset condition, repair priorities, expected year of replacement and costs for replacement of assets.
Underwater and more detailed electrical/ mechanical assessments were not included and should be
considered for future condition assessments.

In asset reporting an approach to linking individual assets to either the sand pumping station or the
sea water supply pumping station has been undertaken. The graph below details the assets
inspected by the combined condition assessments. The asset conditions are ranked according to
the International Infrastructure Management Manual (IIMM). The combined rating of these assets
resulted in an average rating of 2 (Very Good). These assets are grouped consistently and reported
accordingly throughout this document.

Figure 1: Condition by Number of Assets


The breakdown of replacement costs by asset condition is depicted in the graph below. The
importance of this graph is to identify the value of each asset condition and where future investments
are required to renew or rehabilitate the SRS assets. The condition assessments identified are a
number of high valued assets at condition 1 for the sand pumping station and condition 2 for the sea
water supply pumping station which is expected for a facility that is nearly 10 years of age. There
are some lower valued assets ranked at condition 4 for both the sand pumping station and the sea
water supply pumping station; the timing and renewal of these assets will be addressed in the asset
renewal plan that is included in this asset management plan and, will be reflected in Council’s 5 –
10 year Capital Works Program.
