11 November 2003

THE BRIDGES OF MELBOURNE CITY

Division City Assets & Services

Presenter Gordon Duncan, Acting Group Manager Engineering Services

Purpose

1. This report presents a Bridge Management Plan for approval.

Background

2. Bridges owned by the City of Melbourne represent a major asset group. A number of the bridges are over 100 years old and effective asset management is important. They are an intensively used part of the road management network and operate within a road environment where load standards are constantly changing.

3. The Bridge Management Plan puts forward a five-year financial plan and includes indicative costings for the following five years.

Issues

Current Bridge Condition

4. The City of Melbourne has established a five-tier condition rating. The rating is:

4.1. Excellent (a rating of 5): new, or in as-new condition. No change to surveillance schedule;

4.2. Good (a rating of 4): acceptable condition. No change to surveillance schedule;

4.3. Fair (a rating of 3): bordering on intervention level. Bring forward next scheduled surveillance;

4.4. Poor (a rating of 2): at intervention level; and

4.5. Hazard (a rating of 1): presents a hazard to person property or the environment. Immediate containment.

5. The current bridge condition is rated as good except for Arden Street Bridge and Princes Bridge which are rated at between 2 and 3. Ameliorative works are planned.

Load Assessment

6. New Victorian Government load ratings have recently been established. In response to the new ratings, a load assessment and strengthening policy has been established and most of the bridge stock has undergone this load assessment process. As a result of the load assessments, strengthening works have been programmed for Princes Bridge, Queens Bridge (subject to further testing), Arden Street and Macaulay Road bridges.

2

Financial Management Issues

7. In the current financial year, Council has budgeted for expenditure of $2.8M. Much of this funding has been allocated to works on Princes Bridge and a higher than usual bridge inspection regime. Under the Bridge Management Plan, expenditure in year two is also expected to be high at $2.017M as urgent works are continued to Princes Bridge.

8. Details of other structural repairs and inspection and testing costs are listed in Appendix B. Subject to annual review, no further major, single item expense is expected on bridges in the next nine years. It is also essential that adequate funding for on-going maintenance and minor repairs be allocated annually. The Bridges Plan recommends an annual allocation of $100,000 recurrent funding for minor maintenance and repairs.

Stakeholder Management Issues

9. Since 1998, the Victorian Government has constructed four footbridges in the sports and entertainment precinct. In each case, the State Government has asked the City of Melbourne to assume management of the bridge. Council recently resolved not to assume management responsibility for the proposed Birrurung Marr footbridge to the MCG. Negotiations are currently taking place regarding the future management of Sandridge Bridge. The Bridge Management Plan proposes that Council develop criteria to guide future decision-making in this area. These criteria will make clear the conditions under which Council may assume management of a bridge or an aspect of its management. The Plan proposes that as a general principle, Council should not assume responsibility for major repairs/ refurbishment or any works of a structural nature.

Consultation

10. Consultation has been undertaken with VicRoads and the Department of Infrastructure.

Finance

11. Council has allocated $2.8M in the current financial year for bridge repair and maintenance. The Bridges Plan recommends the allocation of $100,000 per annum recurrent funding for minor repairs and maintenance.

Legal

12. No direct legal issues arise from the recommendation in the report. The subject matter of the report and the recommendation are within the functions and powers of the Council.

Sustainability

Connected and Accessible City

13. City Plan 2010 notes the need to:

“ensure a sustainable and highly integrated transport system services City needs and links key assets”.

The Bridges of Melbourne City

A Bridge Management Plan 2003 - 2008

BRIDGE MANAGEMENT PLAN – 1285636 V2 – ENGINEERING SERVICES GROUP 2

Executive Summary

The City of Melbourne is responsible for 13 bridges within the City’s boundary,

ranging from footbridges to heritage listed bridges such as Princes Bridge. The

condition of some of these bridges is deteriorating and asset management

planning is required to maintain and enhance their current condition into the

future.

The City of Melbourne has introduced a bridge management database known as

BridgeAsyst to guide the programming of strengthening and general

maintenance on bridges under its management. Detailed inspections have been

undertaken on all bridges and this information is being loaded into the database

for assessment. By utilising the risk assessment processes within the bridge

management database, bridges with an Overall Bridge Condition (OBC) below

or close to target and components of other bridges with high-risk scores can be

identified.

The Bridge Management Plan includes a five-year implementation plan setting

out scheduling of major repair/maintenance works, inspections and load

assessment plans. Budget estimates have been included.

The Plan also discusses the need to further engage with other stakeholders

involved in the management of bridges such as Heritage Victoria, VicRoads,

VicTrack and neighbouring councils whose requirements/responsibilities need

to be discussed.


Introduction 1. Bridges are an important component of the City of Melbourne’s intensely used

road network. They provide access and amenity for vehicular and pedestrian traffic. Bridges are subject to natural deterioration and operate within a road environment where load standards are constantly changing. Many of the major bridges are over 100 years old. An effective asset management regime is essential to the systematic strengthening and maintenance of bridges.

2. The Council is responsible for 13 functional bridges within the boundary of the City of Melbourne. This does not include Sandridge Bridge which currently has no functional use or Farnsworth Bridge which is predominantly managed by VicRoads. Careful planning is required if the condition of bridges is to be maintained and enhanced. The purpose of this document is to set out a 5-year Bridge Management Plan that enhances the management of the City of Melbourne’s bridges stock by:

2.1 Determining the appropriate bridge maintenance, repair and strengthening regime,

2.2 Establishing an asset management system to guide decision-making. This work, in progress, will provide an assessment of the structural condition of bridges, quantify current and projected deterioration and provide detailed maintenance options.

3. Implementation plans are attached for the five-year financial year period - 2003/04 to 2007/08.

A Bridge Condition Rating 4. The City of Melbourne has established a five-tier condition rating. The rating

is:

4.1 Excellent - a rating of 5. New, or in as-new condition. Requiring no change to surveillance schedule,

4.2 Good - a rating of 4. Acceptable condition. No change to surveillance schedule,

4.3 Fair - a rating of 3. Bordering on intervention level. Bring forward next scheduled surveillance),

4.4 Poor - a rating of 2. At intervention level.

4.5 Hazard - a rating of 1. Presents a hazard to person property or the environment. Immediate containment.

5. The rating is derived from a risk assessment process whereby a score of 1 to 5 is given to every major component of every bridge using level 2 inspection data. These risk scores are aggregated to estimate the Overall Bridge Condition (OBC) of each structure. Details of bridge condition of City of Melbourne bridges are detailed on the following page.


Objectives

6. The following objectives are applicable to the Bridge Management Plan:

6.1 All bridges must safely carry appropriate traffic including pedestrians, cyclists and motorists,

6.2 A system of inspection and repair, which ensures structural integrity, sustainability and safety of the bridge stock will be maintained.

7. The following specific objective is applicable to the Bridges Management Plan:

7.1 No bridge shall have an Overall Bridge Condition (OBC) less than three without special management actions in place to mitigate and reduce the risk.

8. Council currently accepts responsibility for eight road bridges and five pedestrian bridges. A brief description of bridges within the City of Melbourne is provided in the Attachment. This includes a statement of current bridge condition.


Vision 9. The City of Melbourne will continue to manage its bridges stock in a sustainable

way that meets its duty of care obligations to the community.

Policy Framework 10. City Plan 2010, the City of Melbourne’s primary planning strategy, notes the

need to “ensure a sustainable and highly integrated transport system services City needs and links key assets” (p. 26) with the following relevant objectives:

10.1 Provide for an efficient and integrated road freight system that reduces negative environmental effects on residential and public areas,

10.2 Ensure the city’s pedestrian and transport infrastructure connects and links key sites, places and activities, including Docklands and Port Melbourne, with the Central City.

11. The City of Melbourne’s Transport Program (2003-2006) contains a package of initiatives to improve transport access, safety and ease traffic congestion where possible within the City of Melbourne. The Program involves reviewing the current traffic management systems within the City as they effect the CBD and the area immediately around it. It concentrates on initiatives that are solely within Council’s sphere of responsibility as well as some practical initiatives that involve shared responsibility with other levels of Government and/ or the private sector.

12. Under the Local Government Act 1989 and the Road Safety Act 1986, Melbourne City Council has direct responsibility for managing and maintaining the local road network as a Highway Authority. Within the municipality of the City of Melbourne, Council exercises management control over all roads, except for roads declared to be freeways, state highways or main roads under the Transport Act 1983. On declared roads, Council is responsible for parking regulation (where permitted) and VicRoads is responsible for management and maintenance.

13. The State Government has overriding responsibility for many aspects of land use, transport and the environment, with most of these functions managed through the Department of Infrastructure. The Department of Infrastructure’s responsibilities include strategic planning, regional planning controls, ports, some road funding, public transport regulation and public highways.

14. The State Government has developed a draft Road Management Bill that aims to establish a coordinated management system for public roads that will promote safe and efficient State and local public road networks and the responsible use of road reserves.

15. The State Government has recently released Melbourne 2030, a strategy for the development of Melbourne over the next 30 years to accommodate growth in a more sustainable way whilst preserving and enhancing the amenity and lifestyle of the city. The Strategy is intended to deliver better management of the roads system.


Background

The external Management of Bridges 16. The responsibility for day to day management of roads is shared between

VicRoads and the City of Melbourne to varying degrees depending on the road classification.

17. VicRoads are accountable for the management, maintenance and funding of all bridges on declared State Highways, Freeways, Forest and Tourist roads and all declared road bridges over railways. VicRoads have also accepted responsibility for bridges on declared main roads excluding the pavement maintenance which remains the responsibility of the City of Melbourne under the Main and Unclassified roads program (letter from Council to VicRoads dated 22 August 1996 and letter from VicRoads to Council dated 4 September 1996).

18. The City of Melbourne is accountable for management of all bridges on local roads, except bridges over railways. VicRoads may arrange for the City of Melbourne to carry out works on bridges over railways on their behalf.

19. There are also assets attached to the bridges themselves – especially the underside. This includes conduits and pipes belonging to various service authorities. Lighting on bridges is usually owned by utility companies and is therefore their responsibility. These authorities may need to be contacted by the City of Melbourne before any works takes place.

20. Other agencies such as VicTrack and City Link are responsible for management of bridges that support their services (eg. Bolte Bridge). VicTrack (formerly Public Transport Corporation) are accountable for the care and management of rail bridges over roads, local road bridges over railways and rail tunnels and any assets required to support the PTC services.

21. Several of the bridges managed by the City of Melbourne are on the heritage register as managed by Heritage Victoria and a permit is required to undertake work on these bridges.

22. The City of Melbourne has shared responsibility for management and maintenance of Macaulay Road, Epsom Road and Stock Subway Bridges because they share a border with the City of Moonee Valley. The Victorian Government also manages some footbridges.

23. A list of all bridges within the Council’s boundaries, together with the organisation responsible for managing the asset is included in Appendix C.


Database Management – A Process for Managing Bridge Assets

Figure 3.1 Asset Support System

24. The City of Melbourne has purchased a bridge management database known as ‘BridgeAsyst’. Inspections have been undertaken of bridges managed by the City of Melbourne and data on the outcomes of these inspections is being entered in the database. The database provides a framework for Council’s management of its bridges [see figure 3.1] and enables Council to assess the condition of the bridges relative to a pre-set formula. This gives each bridge an Overall Bridge Condition score that can be used to prioritise repair according to the relative risk factor. Information about the categories of information stored within the database is detailed below.

Inventory

25. This includes bridge name, road name, asset number, span, material, geometry details, date of construction, drawing location, location of heritage information, contacts for service utilities on bridge, critical OHS information and a minimum of 3 photographs.

Condition Monitoring and Assessment

26. The City of Melbourne has adopted the practices of the Vicroads Inspection Manual to monitor the condition of the bridges. This involves the following hierarchy of inspections:

Level 1 - Routine Maintenance Inspections,

Level 2 – Bridge Condition Inspections,


Level 3 – Detailed Engineering Inspections and Analysis.

Level 1 -Routine Maintenance Inspections

27. Level 1 inspections are visual checks carried out in conjunction with routine pavement maintenance on a six monthly frequency to check the general serviceability of the structure for road users and to identify emerging problems. The scope of the inspection includes an assessment of the substructure, superstructure and attached services to identify maintenance work that does not required further engineering assessment.

Level 2 – Bridge Condition Inspections

28. Level 2 inspections are comprehensive visual inspections carried out by an accredited bridge inspector. These inspections are carried out on a certain frequency depending on the risk profile of the structure. The main purpose of this level of inspection is to identify current maintenance needs, forecast future changes in condition and estimate future budget requirements.

Level 3 – Detailed Engineering Inspections and Analysis

29. Level 3 inspections are specific or detailed inspections carried out when issues requiring further investigation are identified during the Level 2 inspection process. They are carried out by an accredited bridge inspector with the purpose of assessing the capacity of a structure, identifying and quantifying the current and projected deterioration of the structure, and recommending appropriate management options.

Load Rating

30. Ease of traffic movement and access depends upon bridges being able to carry designated truck weight within the municipality. The current legal loads were adopted in Victoria in July 1999, and are shown in Figure 3.3.

Figure 3.3 – Mass Limits By Vehicle Type

31. In line with these load ratings, a load assessment and strengthening policy has already been established by the Council and most of the bridge stock has undergone this load assessment process. Road Bridges have been assessed in accordance with the Vicroads Bridge Assessment Group Guidelines for


assessing the Load Capacity of Bridges (BAG Guidelines). As a result of the load assessments, strengthening works have been programmed for Princes Bridge, Queens Bridge (subject to further testing), Arden Street and Macaulay Road bridges.

Historical Recording

32. Historical recording allows the review of the bridge history including the maintenance cost incurred and the assessment of the overall condition following maintenance. The historical cost of the work is also recorded for future use.

Risk Management

33. The Bridge Management Database assesses the risk associated with all bridge structures by giving each bridge component a risk score and aggregating this into an overall assessment. The defects of all components on all structures are compared in terms of the probability of failure and the consequences of failure under weighted factors. The risk rating methodology has been extended to calculate an overall condition score for every bridge in the network. This process is useful for identifying bridges where the overall condition of the bridge is such that replacement is an option. The overall score is also useful for benchmarking the condition of the bridge.

Financial Reporting

34. The Bridge Management Database includes a financial analysis module to meet recognised statutory reporting requirements. By adjusting the typical replacement cost rates for typical bridge types or adjusting the replacement dates for the bridge, the bridges can be revalued when required.

35. For each span type, material classification is necessary to provide a replacement cost per square metre, which comprises demolition, design and new construction cost. The following calculations are made:

35.1 The replacement date for the bridges,

35.2 The replacement cost of bridges,

35.3 The depreciated value of each structure,

35.4 The current value of the bridge stock.

Performance Monitoring and Benchmarking

36. The bridges database allows the City of Melbourne to measure the overall performance of its bridges against benchmark condition criteria.

Maintenance Scheduling

37. It is necessary to provide sufficient annual maintenance funds to maintain the overall bridge condition of the bridge stock above the target score and repair all defects with high-risk rating.


Capital Works Scheduling

38. The Overall Bridge Condition score is used to identify bridges that require significant repairs. In extreme cases, replacement may be the more economic option. In circumstances where significant repairs are required:

38.1 the repair cost is estimated together with the after-repair overall condition, thus the expected life after repair

38.2 The yearly-depreciated cost of repair is then compared with the yearly-depreciated cost of the new structure and a conclusion is reached with regard to the optimal option.


Issues

Stakeholder Management

39. The Victorian Government has constructed four footbridges since 1998 designed to improve pedestrian access to major sporting venues in the sports & entertainment precinct. The Government has approached the City of Melbourne to manage and maintain these bridges after construction but Council has declined to accept responsibility for the bridges. Council has recently resolved not to accept maintenance responsibility for the proposed Birrurung Marr Bridge to the MCG. Further discussion with the State Government is required to resolve these management issues.

40. The City of Melbourne should develop a process for managing the transfer of new bridges and the return to functional use of de-commissioned bridges built by the State Government or other third parties. City of Melbourne management of each bridge should be assessed on a case by case basis but Council will develop formal criteria to guide it in its decision-making. This shall include issues such as:

40.1 Extent of community benefit,

40.2 Financial implications,

40.3 Risk assessment,

40.4 Legal implications,

40.5 Heritage and environmental values.

41. Where Council agrees to a management role, a formal management agreement will be negotiated with the relevant third party that clearly delineates the role/responsibilities of each party. As a general principle, Council would not assume responsibility for major repairs/ refurbishment or any works of a structural nature.

42. The City of Melbourne also should discuss ownership and management arrangements with Moonee Valley Council over the Macaulay Road Bridge, Epsom Road Bridge and the Stock Subway underpass. This may involve negotiating regarding a shared costing arrangement for the on-going maintenance of these three bridges. Macaulay Road Bridge, which requires strengthening to meet load assessment requirements, is the main priority.

43. Appendix C lists all the road and footbridges within the municipality – a total of 41 bridges. Of the bridges not managed by the City of Melbourne, 19 are managed by VicRoads (the City of Melbourne is responsible for road and footpath surface on some of these), 6 by VicTrack, 4 by Translink Operations and 1 by Melbourne University. The City of Melbourne will seek confirmation from the organisations responsible for externally managed bridges that all safety requirements are being met.


The Need for Regular Inspections

44. A target minimum Overall Bridge Condition Score (OBC) is 4.0. Ideally all bridges should be maintained so that all structures have an OBC higher than the target. However, funding may not always be sufficient to maintain all of the bridges to such a condition, and an allowance of 10% below the target has been made - provided there are management plans in place to improve the condition. The function of a bridge may also dictate the required OBC. For example, a footbridge does not need to be structurally capable of carrying vehicles (and does not need to be repaired to this level) but may be maintained so as it is safe for its pedestrian function.

45. The minimum OBC for any structure is 3.0. An OBC score below 3.0 indicates the structure has an unacceptable risk profile, relative to its use, as some parts of the structure approaching a critical condition. If a bridge rating falls below 3.0 urgent action is required to manage the immediate risk and implement measures to improve the bridge condition.

46. Based on the fact that the City of Melbourne has Victoria’s most intensively used municipal road network, the recommended inspection cycles is:

x Level 1 Inspections - every six months, x Level 2 Inspections - Bridges with Overall Bridge Score < 3 : yearly, x Level 3 Inspections as necessary following Level 2 Inspections.

47. All other bridges to be inspected every two years.

The Overall Bridge Condition 48. The Overall Bridge Conditions as of January 2003 are represented on Chart One

on page 4. The Chart takes account of each individual component of a bridge working outwards from a risk assessment base. A score of between 3 and 4 is satisfactory. The only bridge currently under 3 is Arden Street. The City of Melbourne has allocated funding in the 2003/04 budget to correct structural inadequacies with the bridge.

49. A 5-year program of works to improve the current condition of bridges has been set out in the Implementation Plan below. The order of priority for repair shall be:

49.1 Ameliorating risk,

49.2 traffic management,

49.3 Support for overall City Plan 2010 theme – eg. accessibility.
