Wagga Wagga City Council // Asset Management Plan // Airport //

This Supporting Section should be read in conjunction with Council’s Asset Management Plan, the Asset Management Policy (which sets out Council's philosophy of asset management) and Council’s Asset Management Strategy (which provides Council with a clear direction and goal for managing the community's $1.185 billion (as at June 2010) worth of assets).

The following map provides details of the Wagga Wagga Airport.

Challenges of the AirportThe maintenance of the airside assets at the Airport is challenging as airport maintenance crews have limited windows of operating times due to aircraft movements. This makes significant routine inspections and auditingchallenging as well.

There are a high number of people who use the airport each year, in 2011 the projected passenger throughput is expected to be 225,000. However, the total numbers of people accessing the terminal is significantly higher than this, contractors, people meeting and farewelling travellers, suppliers and other visitors all add to the total visitations.

The high throughput puts pressure on assets such as the terminal building, roads and car parks, and can make inspections and maintenance very difficult. This high traffic volume leads to the need for increased inspections and maintenance to ensure assets are kept at a satisfactory standard. Forexample, a reseal in the car park could take many weeks to complete due to the need to have all cars vacate the car park. Not only is this difficult as there are insufficient all-weather overflow parking areas, but some vehicles are left in the car park for long periods of time and it can be very difficult to contact the owner.

Airport pavements are not subject to the high traffic that public roads are. Also the point loads of aircraft are much higher than road going vehicles due to the wheel loadings. This results in pavements having very different wear characteristics to roads.

Condition Ratings Reference SheetsThe condition of each asset type managed by Council at the airport is audited against a rating scale which ranges from excellent to very poor. This scale is used as the basis of all assessments of the airport assets managed by Council’s Surveillance Team. The Condition Rating Reference Sheets for the following asset types are used to rate each type of asset managed by Council at the airport:

Buildings

Carparks

Fences

Footpaths

Kerb and Gutter

Linemarking

Sealed Roads

Sewer and

Stormwater

Risk and Condition Rating IndicatorsCouncil also uses Risk and Condition Rating Indicators to determine a prioritised works schedule for the maintenance, renewal and replacement of large asset categories. These indicators are used in addition to the Condition Ratings Reference Sheet to enable further analysis of the worst sections of the asset class.

Risk and Condition Rating Indicators have not been developed for the Airport in this Asset Management Plan. However, as Council, moves towards strategic asset management, indicators may be developed for large asset classes at the Airport, for example the open space.

2 Condition Assessment

Airport


Intervention LevelsTo guide Council’s response to customer requests a set of reactive triggers has been developed for each asset category. These triggers are called intervention levels and include expected response times. The intervention levels and response times for maintenance for the following asset types are used for each asset managed by Council at the Airport:

Buildings

Carparks

Fences

Footpaths

Kerb and Gutter

Linemarking

Sealed Roads

Sewer and

Stormwater

Inspection Regime The condition and risk of assets at the Airport will be assessed simultaneously as part of the Condition Inspection Regime. This inspection will audit the condition of each asset type against the appropriate Condition Rating Reference Sheet and also assess the risk based on location and usage. Each asset managed by Council at the Airport will be inspected in accordance with the inspection regime for the asset type as detailed in the relevant sections of the Asset Management Plan.

The inspections will be in the form of a GPS audit routine for all assets managed by Council at the Airport.

Ad hoc inspections will be conducted in response to customer requests, on a needs basis and where the asset degrades due to un-foreseen or unusual circumstances, like a storm event. These inspections are done onsite by trained Surveillance Officers and the results are captured in Council’selectronic mapping system (ArcGIS).

Airport staff inspect the airport daily to ensure it is fit for purpose.

Life cycle management details how Council plans to manage and operate the asset category at the agreed level of service while minimising life cycle coststhroughout the useful life of the asset.

For most local government assets there are four key phases to the life cycle, namely: acquisition, operation and maintenance, renewal, and disposal.

Costs occur in each phase of the asset life cycle. It is important to attribute these life cycle costs to each phase to allow for effective decision making about how the asset will be managed.

The life cycle costs of assets include:

initial capital investment

operation and maintenance

refurbishment and renewal

administration, overheads and taxes

depreciation

capital use rate charges or rate of return and

disposal of the asset at the end of its useful life

The initial capital or investment cost of a new asset is a significant cost and often dominates the decision as to whether to acquire the asset or expand the infrastructure network. However, it is important to include all the costs associated with each phase of the asset life cycle, including ongoing operation and maintenance, future renewal and disposal.

3 Life Cycle Management

Airport


Target Maintenance EventsThe Airport, is a commercial entity and operates on a cost recovery basis. The maintenance of the airport is not financed by Council’s General Purpose Reserve, but from the income generated by the Airport, which is held in theAirport Reserve. For this reason, maintenance events of the Airport are not included in this Asset Management Plan. However, this information will be considered in future revisions of the Plan as Council moves towards strategic asset management.

The target maintenance events for the following asset categories are used as a guide for each type of asset at the Airport:

Buildings

Carparks

Fences

Footpaths

Kerb and Gutter

Linemarking

Open Space

Sealed Roads

Sewer and

Stormwater

Renewal A detailed work plan for the renewal of assets managed by Council at the Airport is developed annually to support this Asset Management Plan. This renewal program is prioritised based on condition and risk.

DisposalCurrently, Council includes the cost to dispose of an asset in the unit rate of that asset type. As Council moves towards strategic asset management this cost will be captured separately. The Asset Management Plan will be updated to reflect this change as it occurs across the asset types.

When the Airport disposes of an asset, an income often results. The income varies depending on the asset type and the market for the asset at the time.

The Asset Management Plan for 2011 has been developed based on data collation, research outcomes and the results of Council’s internal stakeholder engagement process.

The next stage of the process is to ask the community to identify which asset condition is satisfactory to them. This will begin with an extensive community consultation process. The consultation will be in the form of a community survey which will be conducted online, at community gatherings, through focus groups and stakeholder meetings. The survey will use new technology, be based on images and a simple selection process. The outcomes of the consultation will form the foundation for true community engagement to occur in relation to the management of infrastructure across the Wagga Wagga LGA, in particular the development of agreed levels of service, supported by Council and the community.

As Council gathers data from the community about the level of service for each asset category the outcomes will be integrated into the Asset Management Plan.

Until the outcomes of the community engagement are known Council will provide costings to achieve an average level of condition for each asset category and use this as the level of service.

4 Level of Service

Airport


Current LiabilityCouncil’s current liability of each asset type is the expenditure required to ensure the condition of the infrastructure is average or above.

The current liability of the Airport is estimated to be nil, based on the condition audit performed by Council’s Surveillance Team in 2010. This means that all the components of the Airport have a condition rating of average or above (as at 2010).

Projected Annual Maintenance CostsThe Airport is not financed by Council’s General Purpose Reserve, but from the income of the facility, the Airport Reserve. For this reason, projected maintenance costs of the Airport are not included in this Asset Management Plan. This information will be developed and included in future revisions of this Plan.

However, the project annual maintenance costs for the following asset categories are used as a guide for each type of asset at the Airport:

Buildings Carparks Fences Footpaths Kerb and Gutter Linemarking Sealed Roads Sewer and Stormwater

5 Financial Considerations

Airport


Required Increase to Annual Maintenance Budget per Additional UnitAs the asset base increases it is important to ensure that the annual maintenance budget also increases. As the Airport is not financed by Council’s General Purpose Reserve, the required increase to the annual maintenance budget for additional assets is not included in this Asset Management Plan. This information will be developed and included in future revisions of this Plan.

However the required increase to the annual maintenance budget per additional unit for the following asset categories is used as a guide for each type of asset at the Airport:

Buildings

Carparks

Fences

Footpaths

Kerb and Gutter

There are some generic assumptions made in the management of assets in Wagga Wagga City Council, these are found in the Asset Management Plan. In addition, the following assumptions have been made in relation to the Airport:

The secure area of the Airport is termed ‘airside’ and relates to the area of the Airport subject to Airport security under Civil Aviation Regulation. Whilst Council maintains the Airport infrastructure many of the assets are contained in this secure area.

The airport operates on a cost recovery basis. For this reason targeted maintenance events and their associated costs were researched as part of this Asset Management Plan. These details will be included as this Plan is reviewed.
