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 could 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 bridges 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 shall 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
Used”. If additional appendices are required, then these should be added at the end.

FRAMEWORK FOR ASSET MANAGEMENT ACTIVITIES
1.1
Asset Management Plan
This Asset Management Plan (AMP) is a working document to be used as a tool for the
management of Bridge No. XXXX. It describes the bridge, its operating environment,
associated risks, required levels of service and key activities to ensure that the bridge meets
these levels of service during its service life.
This AMP 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 its life whilst maintaining
defined levels of service.
Figure 1 diagrammatically 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 diagram. The framework shows how one phase feeds into the next.

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 contains bridge information and provides 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 electronic
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 source 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 bridge to achieve the specified design life for
the major structural components (ref. Appendix C). The Durability Plan provides an assessment
of the environment in which 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 appropriate 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. Table 3 to be completed
based on current known information.
Table 3 below lists the main concrete components and their concrete grade, exposure
classification, and minimum and design cover. Add/delete as required. The component titles

KEY DRIVERS
There are a number of key drivers that impact on the management of the bridge. These are
Levels of Service, regulatory requirements, stakeholder requirements and the physical
environment. These 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 No. XXXX is on the XXXX which is defined as an “MFF” road link (multi-lane free flowing)
with the following Levels of Service, subdivided into three main categories: Configuration,
Condition and Road Use (modify values as required):
Table 6
Levels of Service
Value
Configuration
Width between kerbs
≥ 8.0m
Condition
Bridge strength
≥ 95% T44
Roughness (IRI)
≤ 3.4
Rutting
≤ 20mm
Road Use
Road closure due to flooding
Nil
The Levels of Service as described above support the LOS required for the XXXX Highway.
Any failures to meet the required LOS on the bridge will impact on the LOS on the Highway.
For example, any load restriction on Bridge No. XXXX will affect the heavy haulage transport
industry needing to use the XXXX Highway.
Similarly, the LOS on the XXXX 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. XXXX Highway).
The LOS on the State Road Network is of concern to the Managing Director of Main Roads who
is required to report on the asset LOS and other LOS to the Minister for Transport. The Minister
for Transport represents the main stakeholder of the transport infrastructure – the WA State
Government.
3.2
Regulatory 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 Design and Austroads Guide to
Asset Management Part 6: Bridge Performance.
Main Roads Western Australia
Template Rev A
Asset Management Plan – Bridge No. XXXX
Page .11
Outline here any changes that may need to be considered for the management of this bridge
either now or into the future. As an example, there may be increased loadings due to new Code
release (e.g. Austroads ‘92 to AS5100) or changes to guardrail standards (e.g. Level 2 barriers
in accordance with Austroads ‘92 to Regular Performance Level barrier in accordance with
AS5100).
Also outline here any Main Roads or Government policy changes, or any changes to State
Government Legislation.
Discuss any regulatory bodies that may have an indirect impact on the management of the
bridge. For example, the Department of Transport (Marine Safety) is the regulatory body
responsible for the marine safety of navigable waterways and Main Roads has a requirement to
meet any conditions set down by them.
3.3
Stakeholder Requirements
The purpose of this section is to list the key stakeholders and describe the future requirements
of the bridge from the stakeholder’s point of view.
Main Roads is the owner of the bridge, and maintains and operates the structure. The
responsibility for the management of the structure resides with Main Roads.
The organisations and agencies that are key stakeholders in the management of the bridge are
outlined below. Also outlined below are any future requirements that the stakeholders (other
than Main Roads) may have for the bridge.
3.3.1 Owner and Operator
Main Roads – responsible for maintaining the bridge in a safe and serviceable
condition and performing to the required levels of service (refer Section 3.1). Main
Roads’ main role is in developing, implementing and funding regular and ongoing
asset management activities so as to meet the level of service;
ii) Main Roads – responsible for operation and maintenance of all ITS cables,
underbridge and footpath lighting cables, and closed circuit television (CCTV)
cameras (list as appropriate);
i)
3.3.2 Service Authorities
i)
List as appropriate (e.g. Western Power, Alinta Gas, Water Corporation etc). Also
outline any changed requirements for the future (e.g. new services that may be
required).
3.3.3 Bridge Users
Outline demand factors for each, including past performance, factors affecting current demand
for services and factors affecting future demand for services. Use the following list as a guide.
Add/delete as appropriate:
ii)
iii)
iv)
v)
vi)
Vehicle commuters;
Public transport;
Freight, commercial and heavy vehicle transporters;
Pedestrians and cyclists;
Vessels.
3.3.4 Customer Service Advisory Council
The Customer Service Advisory Council provides input into the Customer Services Charter. Its
function is to provide community involvement and input into Main Roads’ organisational
Main Roads Western Australia
Template Rev A
Asset Management Plan – Bridge No. XXXX
Page .12
planning processes and strategic direction. The Council meets three times per year and
consists of industry and community members representing Western Australia’s diverse road
users. The Council provides advice and feedback, from a customer perspective, on the
development of strategy and policy in relation to Main Roads’ products and services, and levels
of service.
3.3.5 Others
Delete this heading or add any others as appropriate (e.g. Local Governments, mining or other
private companies, Department of Planning and Infrastructure etc). Also list any changed
requirements. Also, discuss any political issues affecting the bridge (e.g. in a marginal seat,
history of Ministerial complaints).
3.4
Physical Environment
The physical environment has the potential to affect the condition of the bridge. The key
environmental concerns in relation to the bridge are discussed below (add/delete as required).
3.4.1 Atmospheric
State expected atmospheric conditions affecting the bridge during its life. State the distance
from the coast and any special local conditions.
3.4.2 Ground
State expected groundwater level and any potential impact on the bridge structure.
State any potential for Acid Sulphate Soils (ASS) or other deleterious substances in the ground
water table (e.g. salinity).
3.4.3 Water
State water properties if bridge goes over water course (e.g. salt levels or other deleterious
substances). Also consider scour potential.

CURRENT PERFORMANCE
4.1
Introduction
The performance of the bridge relates to whether it meets the Key Drivers identified in
Section 3. This includes the required levels of service, which for bridges includes configuration,
bridge condition and road use. The performance of the bridge with respect to these key drivers
is discussed 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 various
components that comprise the bridge asset. Condition and performance are two interrelated
concepts and the following important distinctions and relationships between asset performance
and condition should be borne in mind:




4.2
The condition of the bridge 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 expectation) may affect the condition
of the bridge (for example, vehicle overloading).
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), roughness 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

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 hierarchy
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 corporate 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 Planning
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 integrated 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 report
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 increased 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 risks 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. As a minimum, the persons present at the
brainstorming session is the Author, the Asset 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 above), 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. over 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 capacity 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 structure 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 components 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 equipment (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 whether they already exist
Any security requirements (e.g. keys to access abutment doors)
The Inspection Plan, including specific requirements for this bridge, is given in Table 8 below.

Maintenance and Specific Work Plans
7.3.1 General
The Maintenance and Specific Works Plans are updated with the latest Level 2 or 3 inspections,
taking into consideration environmental factors, bridge condition and potential risk to key
structural components of damage, deterioration or failure.
Maintenance and specific works are subject to the same access issues as described in
Section 7.2.
It is important to link the Maintenance and Specific Works Plans to asset condition and adapt
this plan as required throughout the life of the structure.
The key maintenance activities required for the bridge are summarised in Tables 10, 11 and 12
below for Routine and Preventative Maintenance (timber bridges only) and Specific Works.
Material manufacturer product details for future maintenance are included in Appendix E.
7.3.2 Maintenance Procedures
Bearing Replacements
The bearings are a special item that will generally have a design life less than the design life of
the overall bridge. Therefore, a bearing replacement procedure must be prepared for each
structure and outlined below. The procedure should cover the replacement of all the bearings
(including jacking points, maximum allowable jacking, procedure for removal and installation of
new bearing). Only include this section if a procedure exists (generally only apply to new
bridges).
Preventative Maintenance
All preventative maintenance activities shall be carried out in accordance with Main Roads
Timber Bridge Preventative Maintenance Standards (refer Appendix C). Delete if no timber
components.
Add any other maintenance procedures required here.

Preventative Maintenance Plan
Preventative maintenance involves work items conducted at regular intervals of longer than one year. These work items are carried 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.
Based on this definition, a Preventative Maintenance Plan is only relevant for a timber or timber hybrid bridge.

Specific Works usually involve repairs or modifications to structural components with some typical specific maintenance activities including repair of
cracked or spalled concrete, repair or replacement of an expansion joint, replacement of bearings and structural repair of guardrail following major
impact.
Specific maintenance requirements are identified from Level 2 or 3 inspections.
The AMP Section No. is the reference in this AMP that provides justification for the specific works.

Contingency Plan
The recommended remedial and maintenance activities are aimed at reducing the overall
likelihood that an identified 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 required to provide a prompt response in the event of incidents on the road
network, including Bridge No. 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 personnel, plant
and materials. In the event of an incident, Main Roads is also required to liaise with relevant
agencies, including the media.
The Risk Assessment (refer to Section 6) identified significant risks associated with the bridge.
The Contingency Plans to mitigate the consequences of risks that have a Moderate or higher
rating are summarised in Table 12: Author to modify table as required.

Most of these events would involve isolating the bridge and diverting traffic while repairs were
being arranged. Author should include reference here to detour plan if one exists.
Any alternate route for any diversion of traffic must not only consider general vehicular and bus
traffic but also needs to bear in mind period-permit vehicles such as cranes and road trains and
any single trip permit vehicles such as floats and multiple axle trailers.
The Police may need to manage some of the incidents (e.g. person accidentally falling from the
bridge, vandalism or major traffic accidents).
7.5
Financial Plan
The inspection, maintenance and specific works expenditure estimates required for the bridge
over the next 10 years are outlined in the Financial Plan in the Table 13 below and reflect the
items discussed in Sections 7.2 and 7.3. The estimates shown are only for activities for which
Main Roads is responsible.
Costs given in the following Financial Plan for the bridge include traffic management and access
costs. They are based on the best information available at the time and should be reviewed
with each update of this AMP.

Highlight below any items that the reader should be alerted to which are specific to this
structure. 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.

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 individual 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, indemnify 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 IMPROVEMENT
This section should be compiled after all of the other sections have been completed.
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 organisations).
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
Operational Plans.
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 PLAN UPDATE
This AMP is a working document that should be updated on a regular basis as tests and
inspections are undertaken 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 effectively 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:




assess the present condition;
assess the performance;
make comparisons with previous data and information in order to develop a
history of the bridge 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 every 5 or 7 years (modify as appropriate for
timber or concrete/steel, respectively). This should preferably occur immediately after
the detailed inspection of the bridge. 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
