This table is to keep track of the revisions to this template. The Template Rev number in the
footer shall not be changed and the Author should be using the REVISION STATUS
section of
the AMP.

Multiple Bridges:

This template has been specifically written
to suit a single
bridge. However, any number of
bridges could be included in the same plan if they are likely to be managed as one group of
structures. For example, they co
uld be along the same
section

of road, constructed at the same
time and/or have similar physical and environmental characteristics. The Asset Manager shall
determine
which bridge
s

can be grouped in the one Plan. In this case, any differences between
the
bridges shall be described by exception.

Text
Legend
:

Text in black should generally be left as is, but
can

be modified as required
.

Italics

and blue
are comments to guide the author in what is required in that section and must
be
deleted and replaced with

the author’s text.

Black text in yellow highlight

may need to be changed but has been included as a starting point
for the author.
Irrelevant items sh
all

be deleted.
The highlight shall be removed in
the
final
version.

Appendices
:

It is intended that the

Appendix numbering is fixed. If an Appendix is not used, then
state


Not

1.1

Asset Management Plan

This Asset Management Plan (AMP) is a working document to be us
ed as a tool for the
management of Bridge No.
XXXX
. It

describe
s

the bridge,
its operating
environment
,
associated risks, required levels of service and
key activities
to ensure that the bridge meets
these

level
s

of service during its service life.

This A
MP

provides a detailed guide for appropriate asset management practices, processes
and activities specific to the bridge. When implemented, these will aid in efficiently managing
the physical and operational attributes of the structure so as to prolong it
s life whilst maintaining
defined levels of service.

Figure

shows
a framework

for the
cycle of bridge management

activities
.
There are six
phases
to the
framework

which are mapped to the
nine

remaining
sections of the
AMP. For reference, the section numbers corresponding to each
phase are

displayed on the
outer ring of the

Bridge Management System

The Bridge Management System (BMS) is being progressively developed and will ultimately
contain the following modules:



Programme Management



Bridge
Enquiry



Bridge Inventory



Inspections



Load Rating & Heavy Vehicles



Evaluation & Strategic Review



Administration

The BMS has many functions, including a suite of tools to assist asset managers to do their
work.


In particular, it provides a system to develop

optimum works programmes and capture
the cost of works against the bridge.

The system records the decision making behind the
development of works programmes and supports consistent asset management planning across
regions in Main Roads.

The BMS contain
s

bridge information and provide
s

links to other systems containing bridge
information (e.g. IRIS).


This information includes inventory data, condition data, planned and
completed work items, photographs, drawings and reports.

In particular, there are elec
tronic
links between the BMS and AMPs.

It is important that information is not unnecessarily duplicated in the BMS and AMPs.

Where
information and data is available in the BMS, the AMP will provide summary information only
and reference the BMS as the sou
rce of more detailed information.

In general, the AMP is a strategic document, typically updated on a 5
or 7
yearly cycle

depending on bridge type
.

The AMP identifies required asset management activities such as
maintenance.

The BMS is the system that is

used to schedule and deliver work.


It generally
contains more detailed information which is updated frequently depending on the type of
information
.

2.4.4

Durability

and Exposure Classification

A separate Durability Plan was prepared for
the b
ridge to achieve the specified design life for
the major structural
components
(
ref
.

Appendix C
).

The
Durability
P
lan
provides
an assessment
of the environment in whic
h the
structure is

to be constructed and establishes minimum
performance requirements to achieve compliance with the design life.

The Durability Plan sets out a process

to be followed during the design and construction of the
bridge to
achieve an appropria
te level of durability
.


It requires not only certain parameters to be
included in design but complementary specifications, method statements and process control
plans for adequate documentation of construction procedures and material supply. Verification

that this process has been followed

is then documented through quality systems and inspection.

If no Durability Plan exists, then note as such and delete text above.

here are
a number of
key
drivers that

drivers
are discussed below
.

3.1

Levels of Service


Main Roads

has developed a number of Levels of Service
(LOS)
relevant

to the management of
bridges.

These LOS are called
Investigatory Criteria.
The Investigatory Criteria for various link
categories are discussed in the document “2006 AMP Standards Review Project



Review of
AMP Standards”.

The definitions of the various link categories are found in the document
“Guidelines for Creation of New Links and Review
of
Existing Link Categories and Extents”
dated November 2010.

Bridge

XXXX

will affect the heavy haulage transport
industry
needing

to use the
XXXX

Highway
.

Similarly, the
LOS
on the
XXX
X

Highway

will impact on the LOS
elsewhere
on the State Road
Network.


For example, load restrictions on the
XXXX

Highway

may result in heavy haulage
having to use another part of the network (e.g.

the WA State
Government.

3.2

Regul
atory Requirements

There is no external regulator in relation to the
management of the
bridge
,

so Main Roads sets
its own levels of service in liaison with the relevant stakeholders and based on national
guidelines and best practice established by bodies such as Australian Standards and
Austroads.


These include Australian Standards AS5100 Bridge D
esign and Austroads Guide to
Asset Management Part 6: Bridge Performance.

CURRENT PERFORMANCE

4.1

Introduction

The performance of
the b
ridge relates to whether it meets the
Key Drivers
identified in

Section

3
.
This includes the required levels of service, which for bridge
s

includes
configuration,
bridge
condition
and road use.

The performance of the bridge with respect to these key drivers
is di
scussed in turn below.

The author should keep the following in mind when discussing the current performance of the
bridge

and how this relates to bridge condition
.

The condition of the asset relates to individual or combined material deterioration of the v
arious
components that comprise the bridge asset. Condition and performance are two
inter
related
concepts

and t
he following
important distinctions and relationships between asset performance
and condition
should be borne in mind
:



The condition of the brid
ge is not a measure of its performance
;



The performance of the bridge is not a measure of its condition
;



The condition may impact on its performance (but not necessarily, depending on
severity); and



The performance of the bridge (or the performance expecta
tion) may affect the condition
of the bridge (for example, vehicle overloading)
.

4.2

Levels of Service

4.2.1

Configuration

Discuss
adequacy of the bridge width between kerbs
.

4.2.2

Bridge
Condition

Discuss bridge strength
(referencing any load rating undertaken), roughnes
s and rutting. The
last two would generally only relate to bridge approaches, but could also relate to timber bridges
with a road pavement surfacing (rather than a structural concrete deck).

4.2.3

Road Use

Discuss
known road closures due to flooding
.

4.3

Regulatory

Requirements

Discuss here any non
-
compliance to current Codes, Main Roads policy, government legislation
etc.

4.4

Stakeholder Requirements

Discuss here where the bridge does not satisfy the requirements outlined in Section

3.3
.

4.5

Physical Environment

Discuss the performance of the bridge in terms of
its environment and specifically where
a
component may not meet the specified design life or serviceability. For examp
le, deterioration
due to corrosion, abutment scour, etc.

BRIDGE STRATEGY

A bridge strategy is required to ensure that the planning of asset management activities at the
bridge level are aligned with the higher level strategies for the Link, the Regional

Network and
ultimately, the Main Roads’ Network.

The strategy provides broad guidance on what asset management activities are required
including any major upgrading works.

The strategies influencing the management of the bridge can be considered in a hi
erarchy
consisting of three levels


Corporate, Regional and Bridge. The bridge strategy needs to
support the regional strategy which in turn needs to support the corporate strategy.

These are described below
.

5.1

Corporate Strategy

There are a number of cor
porate strategies relevant to the management of bridges.


These form
part of Main Roads’ Strategic Plan 2k12 as listed below:



Strategic Approach to the Network



Excellence in Asset Management



Sustainable, Efficient Delivery of Projects



Network Operations Pl
anning



Safe Road Network Access



Reliable and Efficient Road Network Access



Road Network and User Information

Details of these strategies can be found on the Main Roads’ website
www.mainroads.wa.gov.au
.

Many of these strategies identify the importance of in
tegrated planning across the Main Roads’
Network and the role of Asset Management Plans in supporting this objective.

5.2

Regional Strategy

The
XXXX

Regional Road Network Plan includes asset management planning and investment
requirements for the
XXXX

Region.


It contains the future funding requirements to manage the
National Highways and State Roads within the Region over a 10 year planning horizon.

Underpinning this Network Plan are strategies included in the Link Plans which have been
developed for each
link in the Region covering:



inventory details (e.g. road width)



condition data (e.g. roughness/rutting)



the number of bridges on the Link that do not meet the Investigatory Criteria


refer to
Section
3.1

(e.g. strength, width between kerbs).

The
XXXX

Regional Road Network Plan can be found on the Main Roads Intranet site for the
Road Asset Planning Branch.

Link Plan
XX

containing Bridge

No.

XXXX

is a standard rep
ort
generated in RAPID.

Describe here the specific regional strategy relevant to this bridge. For example, the Link Plan
may indicate that the bridge could become redundant in 15 years time due to a major bypass
being constructed, or a section of the Link

may be duplicated and become a part of a major
highway extension.

Another example is if the Link is part of a High Wide Load Route where the
strength and width of the bridge may be critical.

5.3

Bridge Strategy

Describe here the bridge strategy which should
align with the Regional Strategy. For example,
the bridge may require minimal maintenance as it will be demolished in the near future.

In
another example, the bridge strategy will need to cover the asset management activities
required for future increase
d traffic volume and/or loadings.

RISK
MANAGEMENT

Risk management is a systematic method of establishing the context, then identifying,
analysing, evaluating, treating, monitoring and communicating the risks associated with an
asset (or activity) to
minimise losses and maximise opportunities.

Main Roads’
Corporate Risk Management Process
provides guidance on
identifying and
assessing
risk
s associated with its assets, including Risk Rating Tables which enable risks to
be
evaluated and ranked
.
For the
purposes of identifying and assessing the risks associated with
Bridge No.
XXXX
,
an onsite

brainstorming session was held which included the Author
,
XXXX

from Main Roads and
XXXX

from
XXXXX
.

Table
7

below

summarises the
risks identified for the bridge

and the proposed treatments
.
Author to add, delete or modify
as appropriate.

The purpose of the risk assessment is to identify, evaluate, rank and provide strategies or
treatments to minimise these risks.

The risk
assessment

shall be undertaken
in accordance
with the latest copy of Main Roads’ Corporate Risk
Management Process

(refer Appendix C)
.
The Risk Tables included in this document are to be used to evaluate each risk.

The risks are to be
ideally
brainstormed on site. A
s a minimum,
the
pe
rsons
present at the
brainstorming
session
is the Author, the A
sset Manager and Project Manager from the Region
,

and one other person either from Main Roads or the Author’s organisation
,

not directly involved
in the preparation of the AMP.

Treatment can
either be identified as part of the brainstorming
session or at
a later date by the Author.

Risks could come
from
failing to meet levels of service, or regulatory and stakeholder
requirements; or from an unforeseen environmental or design event.

In general, only significant risks should be
included

(e.g. Medium or ab
ove), however, events
which have been highlighted elsewhere in the AMP, but have a low risk level, should still be
included. Events which do not specifically put the asset at risk (e.g. items thrown from bridge)
should be included where relevant (e.g. ove
r electrified railway), since the risk only exists
because the bridge exists.

Any residual risks identified in the Design Report are to be transferred here (applicable to new
bridges only).

OPERATIONAL PLANS

The asset management activities

required for Bridge No.
XXXX

are load rating, inspection and
maintenance. Supporting these activities
are
a number of operational plans. These are
outlined below.

7.1

Load Rating

Structures Engineering
is

responsible for arranging load ratings and therefore

an operational
plan has not been provided.

The need for a load rating is assessed based on the outcomes and recommendations from the
inspections and/or condition surveys. Additionally, load ratings may be instigated as part of an
investigation of load ca
pacity of the bridge to accommodate structural modifications or higher
design loadings.

The current load rating for the bridge is summarised in
Table
5

of Section
2.9
.

7.2

Inspection Plan

Bridge
inspection is

a vital asset management
activity
, and should therefore be carefully
planned in order to optimise the assessment of a structu
re and the data collected in a cost
effective manner.

All inspections shall be carried out in accordance with the relevant Main Roads’ inspection
guidelines which are referenced in Appendix C.

Inspection of Bridge
No.
XXXX

requires access to the various
co
mponents of the bridge
.
Given
the high road usage and vertical clearances, special care will need to be taken to achieve safe
working
procedures.

No
special provisions, in the form of special access platforms or similar,
have been incorporated in the
design.


General requirements for inspections
are

(modify as
required)
:

Include
here
any specific access requirements that may be relevant for this bridge. Aspects to
consider include:



Safe parking location for inspector vehicles



Temporary access equipmen
t (e.g. ropes/harnesses, ladders, transportable stairs,
cherry pickers, underbridge inspection unit)



Traffic management requirements (e.g. lane closures, spotters)



Whether Safe Working Procedures are required (e.g. inspection of enclosed box girders)
or wh
ether they already exist



Any security requirements (e.g. keys to access abutment doors)

Preventative maintenance involves work items conducted at regular intervals of longer than one year.

These work items are carri
ed out before or at
an early stage in the development of defects (e.g. timber rot) aimed at preventing occurrence or progression of the defect.

It is undertaken on a
proactive rather than reactive basis.

Contingency Plan

The recommended remedial and maintenance activities are aimed at reducing the overall
likelihood that an identifie
d
failure
may occur. However, no matter how low the likelihood, there
can be no absolute guarantee that such an event will not happen. Contingency Plans aim to
minimise or manage the consequences of identified
failures
, should they occur.

Main Roads

is r
equired to provide a prompt response in the event of incidents on the road
network, including Bridge

XXXX
.

This

service is required to be available 24 hours a day, 7
days a week, having ready access to all necessary resources including skilled personn
el, plant
and materials. In the event of an incident,
Main Roads

Review of AMP









Modify

r
esponsibilities as appropriate for the bridge. Add
service providers (e.g.
Western Power, Water Corp, etc) or other agencies (e.g. Public Transport Authority,
Local Government Authorities, etc as appropriate).

Highlight
below

any items that the reader should be alerted to which are specific to this
structu
re.

In the case of a bridge over railway where there is a Memorandum of
Understanding (MOU) covering responsibilities for the management of various
components on the bridge, the MOU should be referenced here and
Table
14

amended
to suit the MOU.

Some common aspects are provided below.

Main Roads delivers the maintenance of its road network through a number of regionally
based Integrated Service Arrangements (ISAs).

Where Main Roads has the

responsibility for maintenance on the bridge as shown in
Table
14

above, this can be
delivered using the Integrated Service Provider (ISP).

The Metropolitan Region ISA covers the
maintenance and repair
of Main Roads
'

electrical assets across the State such as the roadway lighting for the bridge.

Inspection and maintenance of service attachments to the bridge is the responsibility of
the indi
vidual service authorities. In accordance with the Main Roads
'

Standard
Conditions of Service Attachment, the service authority must take full responsibility for
the erection and subsequent maintenance of the attachment including all associated
costs, ind
emnify Main Roads against all claims arising from the erection of the service,
and relocate the service as may be requested by Main Roads.

OPPORTUNITIES FOR IM
PROVEMENT

This section should be compiled after all of the other
sections
ha
ve

been comple
ted.

Any aspect of the bridge and its environment can be considered including:


-

Improvement of the performance of the bridge


-

Applications for new or emerging technologies


-

New work practices (better work practices adopted from other
organisatio
ns
).

For example, a new coating technology for concrete durability is being considered for the
bridge, but a firm decision has not been made and therefore has not yet been included in
O
perational
P
lans.

This section can also be used as a section where
ideas can be collected and retained
when staff changes occur within the structures asset management area of Main Roads.

ASSET MANAGEMENT PLA
N
UPDATE

This AMP is a working document that should be updated on a regular basis as tests and
inspections are un
dertaken and new information becomes available.

As the
key
drivers and

condition change over the lifetime of the structure, this Asset
Management Plan must be updated to reflect these changes
.

This is necessary
to
ensure
that Bridge
No.
XXXX

is effectiv
ely managed in a sustainable and economic
manner, and continues to meet all
the levels of
service requirements.

The purpose of the AMP
update
process
for
the bridge
is to:



a
ssess the present condition;



a
ssess the performance;



m
ake comparisons with previous

data and information

in order to develop a
history of the
b
ridge and predict future behaviour; and



update
the
Operational Plans.

It is intended that the AMP be updated as required by the Asset Manager Structures
(AMS),
XXXXXX

Region, but generally ev
ery
5

or 7

years

(modify as appropriate for
timber or concrete/steel, respectively)
.

T
his should
preferably
occur immediately after
the detailed inspection of
the b
ridge.

However, where
significant changes to the key
drivers or
the bridge
occur

within that timeframe, the impact of these changes shall be
taken into consideration
.

Earlier
update
of the AMP may be required under such
circumstances.

Every revision status is recorded in the Revision Table as shown at the beginning of this
AMP.
