Technical Notes 2024, Issue  20 - EDC 3-year Carriageway and Footway Resurfacing Programme  

1. This technical note is intended to provide an update to Elected Members on the notional Roads Carriageway & Footway Resurfacing Programme for 2024/25, 2025/2026 and 2026/2027. 
2. he list will be finalised, and an Annual Programme confirmed for 2024/25 in April 2024 once the capital budget for the year has been confirmed. 
3. The remaining locations will be monitored in the interim period, with an annual programme confirmed for 2025/2026 and 2026/2027 at the start of each respective financial year, once capital budgets have been confirmed for the year. 
4. It is necessary that whatever funds are available are spent on the correct schemes at the right time and that schemes are prioritised using optimisation methodologies to maximise risk reduction and minimise whole life costs. 
5. The methods that East Dunbartonshire Council use to optimise our programme have been developed from best practice methods found in “Well-Managed Highway Infrastructure –A Code of Practice”.
6. The carriageway and footway element of the capital programme is based on a scheme of prioritisation which uses condition assessment scores; prioritisation criteria; and weightings to determine which projects should be prioritised for investment.
7. The condition of East Dunbartonshire Council roads is assessed annually as part of the Scottish Roads Maintenance Condition Survey (SRMCS), an independent survey of road conditions in all 32 Scottish local authorities. The survey provides each local authority with a Road Condition Index (RCI) which identifies the percentage of roads in need of maintenance.
8. The current RCI score is 31.8% which is an improvement on the previous survey score of 34% (2019) which demonstrates that the overall condition of the carriageways has improved since the previous survey. The Scottish average RCI is 33.6%
9. A visual inspection by road officers is source of accuracy on the condition of the network, in greater detail.
10. In addition, and for the first time, the Service utilised Gaist Surveys (Unrivalled roadscape intelligence - Gaist). This full network survey allows the Roads Network Operations team a snapshot of reliable carriageway condition data, that will empower the team and officers to make the best investment decisions based on accurate data. 
11. The Team also investigates carriageway and footway maintenance issues to target improvements. The team analyse condition data available for each asset to identify need for maintenance and/or improvement. 

• Network Hierarchy – the team ensure that greater priority is given to roads and key assets on roads that have the greatest usage or need. 
• Risk – the team will give a higher priority to schemes that pose a risk to public safety. 
• Value for Money – the team will use the right treatments at the right time in order to produce cost effective solutions. 

12. Network Management – the team endeavour to ensure works are programmed to minimise disruption to users and maximise benefits to the community, by combining schemes for different assets together where possible. For example, programme traffic sensitive roads during school holidays, if possible, etc.
13. Each asset has is own set of prioritisation criteria and weighting sets based on the principles above, which consider the unique attributes and requirements of each asset. 
14. It is the aim of the Roads Network Operations teams to deliver all of the schemes listed in this report over a three-year period. However, this may not be possible due to unforeseen or emergency works causing potential conflict on the network. This is why there needs to be an element of flexibility in the programme to allow officers to react to any changes that may arise. 
15. If a location is not delivered due to a conflict it will remain on the overall programme and will be re-prioritised for delivery in a future financial year, or will be on hold until deploy of a suitable contractor i.e., locations contaminate with coal tar 
16. The capital work programme will be reviewed regularly to ensure that any adjustment is made to the programme as soon as possible, with these reflecting in the annual/quarterly updates issued to Elected Members in April, July, October, and January each year. 
17. The aspirational programme of 2024/25 is laid out for your information, but this may alter once the capital budget for 2024/25 is confirmed. The programme is based on the capital allocation for the current year which was used as a guide to allow for preparations to be made prior to any budget decisions being taken by Council. 
18. Footway and Carriageways are a maturing asset and in constant use, so the condition will change over time and it is important that there is recognition that the resurfacing programmes are provisionally only at this time. These will be subject to change depending on the outcome of the annual or ad-hoc/reactive condition assessment review process; result of coal tar; conflict with utility works; weather permit; and any other unforeseen circumstances. 
19. The investment in the East Dunbartonshire Council carriageways and footways improves the accessibility and safety of the road and footway network and therefore has a positive impact for all users, particularly older people, and those with a disability.
