Marlborough District Council Roading Assets - Activity Management Plan 2015 - 2018 SECTION 1 EXECUTIVE SUMMARY be considered as part of the development of a management strategy. If an increase in the level of service is desired it is possible to achieve this by the following means: Maintaining an accurate asset database (estimated cost +$5k/year) Undertaking annual condition rating surveys and scheduling maintenance/ renewals based on those surveys (estimated cost +$5k/year) Undertaking more regular maintenance inspections (estimated cost +20k/year) Undertaking more regular footpath cleaning (estimated cost +$50k/year) Renewing footpaths only in concrete (estimated cost +$50k/year) iv. Reduced Level – i.e. consider reducing the level of service to reduce costs. This would not be a viable or popular option as the current level of service is only just meeting current expectations and will not meet future expectations. This option is not considered any further. 1.6.7.4 Demand / Growth New footpath expenditure can occur in the following ways: Extension of the network where there is no asset at present (such as providing footpaths on both sides of the road where pedestrian volumes are high) or to improve the level of service – this can be driven by customer demand or safety studies CBD and commercial area upgrades Extension by subdivision or development A reasonable expectation is that the footpath network will grow as a result of new subdivisions at a rate of 0.2% per annum over the life of this plan. 1.6.7.5 Life Cycle Management A full survey of footpaths has been undertaken and valuations included in the asset valuation inventory. The maintenance of footpaths falls into two categories: Reactive Maintenance (Routine Maintenance): reactive works to maintain Level of Service (e.g. repair joints, sunken pavers, etc) Proactive Maintenance (Renewals):inspection and maintenance programmed to prevent asset failure (e.g. condition inspections, resurfacing of sealed and asphalt surfaces, reconstruction of failed sections of path, etc) Currently lifecycle management is achieved through the application of a maintenance contract specification which requires the maintenance contractor to have an inspection programme to monitor the condition of the footpaths. A separate contractor is engaged to undertake the physical maintenance and renewal works. A summary of the financial Forward Works Programme (FWP) for structures is appended to this section. Footpaths will need to be replaced as they reach the end of their serviceable life. The expected lives of the different footpath types are listed below. Both asphaltic concrete and sealed footpaths need to be resurfaced midway through their expected life to maintain the life of the asset. Approximately 3.6km of asphaltic concrete and 0.5km of seal will need to be resurfaced annually. Resurfacing is undertaken under the existing renewal budget.
