6 Maintenance works prioritisasion - Robert Rowe

Maintenance works – Pyrenees Shire Council
While many Councils expend a great deal of effort in prioritising
their renewal works programs, far fewer Councils seem to devote
the same effort to prioritising their maintenance works activities.
Given the need for a greater focus on maintenance in times of
natural disasters and in times of fiscal restraint, Pyrenees Shire
Council face many issues “post the floods”. The following outlines
the way forward for the Pyrenees Shire Council
Pyrenees Shire is located in the Central West of Victoria. It sits
between Ballarat , Ararat, Maryborough and St. Arnaud.
Some very good wines are produced in the Pyrenees region and it is
also a very productive agricultural region covering 3,500 square
The shire takes its name from the ranges in the north, named by
Major Mitchell in 1836 as they reminded him of the Pyrenees in
North of the Pyrenees Ranges there is a warmer, drier climate, with
rainfall of about 650 millimeters a year. South of the Pyrenees Ranges
is a cooler, wetter climate with rainfall in excess of 750mm per year.
Four major highways run through the region.
The Western Highway, through Beaufort, is the main road
route from Melbourne to Adelaide and Perth.
The Sunraysia Highway runs through the north of the Shire to
Mildura, connecting with the Western Highway at Ballarat.
The Pyrenees Highway runs centrally through the Shire, east
to west from Castlemaine , through Maryborough to Ararat.
The Southern section is serviced by the Glenelg Highway
linking Melbourne with south-western Victoria.

The Victorian Floods
September 5th 2010 storm event.
In a typical 1-100 year event, over 13 hours, rainfall is calculated at
7.8mm/hr .
Pyrenees Shire experienced 250mm of rain falling over a 13hr period,
with an average 19.5mm/hr.
This event caused $4.8million damage to assets
18Th December 2010 storm event.
We had not finished assessing the damage from the December 2010 event
when a 5 day storm event occurred, peaking on January 14th 2011
At the peak of the storm 82.5 mm fell in 1 hour and on the 14th January a
total of 274mm fell in 8 hours. This event caused in excess of $22 million
worth of damage to Pyrenees Assets
• Over 4154 flood defects identified
on Roads, Bridges & Major Culverts
• 1134 defects were identified
where trees were uprooted or
fallen limbs or widowmakers .
These were assessed as impeding
assets performance or potential
risk to workcrew safety.

Damage related to maintenance?
Could the extent of damage have been minimised by more
effective maintenance processes ?
Some Yes, some maybe , but for this size event most
probably not. In smaller, isolated storm event, well
maintained assets would definitely lessen the impact .
Pyrenees now undertaking a review and rethinking
maintenance practices.
Improve maintenance activities ….lessen the exposure to
Council is a participant in STEP and aims to achieve “Core Competency”
under the National Asset Management Assessment Framework.
A Key NAMAF element is to have adopted AMPs in the major
Pyrenees now have AMP’s for roads, buildings and structures, bridges
and major culverts with improvement actions clearly documented for
each category of asset.
Our response to maintenance post floods will be to ;
• Review maintenance processes (AMP content follows IIMM layout)
• Review field maintenance and planning process
• Develop a Defect inspection manual
• Come up with a priority for maintenance works
• Review response times
• Standards and specifications
• Understand maintenance costs
Some other considerations
Relationship with condition surveys. Condition level assessed
against defects/maintenance inspections….does it match your gut
Improve the qualifications and skills of inspectors
Work flow/conducting the inspections
Defects and maintenance items to be digitally recorded – no paper
Cost implications (extra cost of conducting inspections, extras cost
by identifying work!!)
What have we come up with
Regional Example
Excellent work by Ballarat City - Draft Level 1Inspections - Bridge
Provides excellent guide.
• Sharing of documents and ideas through Central Highlands Asset
Management Group.
• Program maintenance and condition inspections frequencies with
a view to accommodate longer term forecasts (Bridges 5-4 years)
• Look at how we can minimise risk by undertaking maintenance
• Take out any guess work in council operations by establishing
processes and practices
• Proper maintenance extends life not only against regular wear
and tear but can also offer some protection against bigger events
• Consequence of not doing maintenance (maintenance does not
cost, it pays)
• Need to extend this thinking across all assets
The Floods, while devastating and an extreme event, they
created a realisation of the potential improvements in our
AM maintenance practices, procedures and planning.
Council must continually apraise its maintenance priorities.
Avoid wobbling plates …keep things spinning nicely
