NORTH AYRSHIRE COUNCIL 28 April 2026 Cabinet Title: Roads, Structures and Street Lighting Maintenance Programme 2026/27 Purpose: To seek Cabinet approval of the proposed Roads, Structures and Street Lighting Maintenance Programme for 2026/27 Recommendation: That the Cabinet (a) notes the approach taken to determining the asset maintenance programme for roads, structures and street lighting; (b) approves the maintenance programme for 2026/27, as shown at Appendix 1; and (c) notes that the programme will be issued to the Locality Planning Partnerships for information. 1. Executive Summary 1.1 North Ayrshire Council has a statutory obligation under the Roads (Scotland) Act 1984 to manage and maintain its public road network. The adopted road network within North Ayrshire has a total length of 1054km. The core roads assets are currently estimated at a value of approximately £1.7billion. 1.2 The Council’s Roads Service has adopted an asset management approach to road maintenance to allocate available road maintenance funds to locations that will offer the most beneficial return on the investment. 1.3 The Roads Asset Management Plan (RAMP) follows the recommendations contained within the ‘Well Maintained Highway’s Code of Practice, ensuring that the Council’s statutory obligations as delegated Roads Authority are met. 1.4 In complying with the Code of Practice, an effective regime of inspection, assessment and condition recording is well established which assists in not only providing a road network for the future but one that promotes social inclusion and contributes to economic growth within the area. This approach also ensures the Council is providing value for money on any investment attributed to road maintenance. 1.5 The proposed Roads, Structures and Street Lighting Maintenance Programme 2026/27 is attached in Appendix 1. The Programme is based Revenue and Capital budgets approved at the Council’s budget setting meeting on 25 February 2026.

2. Background 2.1 North Ayrshire Council is responsible for the maintenance of the adopted local road network including lighting and structures assets as well as its other non-adopted road assets. However, the Council has no responsibility for the maintenance of the Trunk Road Network which falls to Transport Scotland and their management contractor, Amey. The Trunk Road network includes the A78, the A737 from Kilwinning to the Renfrewshire Boundary and A738 from the Pennyburn Roundabout to the A737 Dalry Road Kilwinning. 2.2 North Ayrshire Council’s roads are the Council’s largest community asset and play a vital role in supporting the local and wider economy by facilitating the movement of people, goods and services and connecting people with economic and social opportunities. 2.3 The proposed Roads, Structures and Street Lighting Maintenance Programme for 2026/27 has been developed in accordance with the strategy contained within the Roads Asset Management Plan (RAMP) to deliver the maximum return on investment and ensures the provision of an effective road network throughout North Ayrshire. 2.4 Road Condition is measured nationally through the Scottish Road Maintenance Condition Survey (SRMCS). The measure in place, the Road Condition Index (RCI), records the percentage of the Council’s roads which should be considered for maintenance. North Ayrshire’s RCI has been improving steadily in recent years. The 2023 figure of 34.8%, improved to 32.5% in 2024, and is currently at 30.6%, published 2025 figure. The Council’s ranking amongst the 32 Local Authorities for the Road Condition Index has also improved from 22nd in 2023 to 10th in 2025. 2.5 The estimated carriageway maintenance backlog figure for North Ayrshire is currently £38.5m. The ‘steady state’ figure for maintaining our roads at present condition is £5.5m per year. The approved capital budget supported by revenue funding is £8.3m for 2026/27. This level of investment is greater than the ‘steady state’ figure and will therefore contribute to an improvement of the road network. 2.6 Road lighting condition is measured through programmes of structural and electrical assessment and testing and is complemented through the ongoing review of age profile and material type life expectancy. The results are categorised and recorded in the lighting asset management database to inform a prioritised list of replacement schemes. Lighting is allocated an annual Capital budget of £1m to address a ‘steady state’ position of maintaining our lighting at present annualised depreciation rate. The programme of carriageway investment will see carriageway investment in locations yet to be included within the prioritised lighting condition criteria. This will be addressed by some reprofiling and by the provision within the carriageway works of installing regular road crossings and ducting to allow lighting improvement works when reaching prioritisation status based on their condition at future investment cycles. 2.7 Bridge and retaining wall condition is also evaluated through a robust inspection programme. General inspections are undertaken every 2 years, while an in-depth ‘principal inspection’ is carried out every 6 years and the results of the inspections are
Page 3
used to inform work programmes. The results of the inspections are input into a Structures database which is then used to calculate an average Bridge Structure Condition Index (BSCIav) based on the total number of assets. The BSCIav is currently 82.76 (2024/25 figure) which is within the ‘good’ classification of 80 to 90. Structures have an allocated capital budget of £560,000. 2.8 Details of how condition assessments are carried out and how roads, structures and lighting locations are prioritised for inclusion in our maintenance programme are provided in Appendix 2. The assessment matrix used for scoring and ranking structures for inclusion in the Structures Maintenance Programme is attached in Appendix 3. 2.9 The road maintenance programme in 2025/26 mitigated high inflationary cost increases through two factors - by forecasting higher projected costs and building this into the programme early in the financial year and, secondly, the Roads Minor Works Framework Contract price being held for the first 6 months of the year. Works completed by the operational team and any works tendered since then were subject to inflationary rises in material and plant costs as well as contractor price increases. The 2026/27 road maintenance programme has been prepared using increased rates from 2025/26 costs to allow for further inflationary rises in costs and to ensure that programmed works can be completed. 2.10 The following locations are being carried over from the 2025/26 maintenance programme. This resulted from lack of contractor availability, design changes and ferry restrictions: • Lovat Street, Largs • B714 Dalry Road, Saltcoats • B896, Millport • Park Terrace, Lamlash 2.11 The following structures contracts are being carried over from the 2025/26 maintenance programme, with feasibility and design works ongoing. This was due to adverse weather resulting in various coastal erosion (Ring Road Arran) and landslip (B871 West Kilbride) issues across the network. These unforeseen activities required urgent attention, resulting in the need to reallocate funding and staff resource from these planned projects to design and manage the unplanned repairs. • Lynn Drive Footbridge, Kilbirnie • Kirkland Road Footbridge No.2 Glengarnock (B777) • Barrie Terrace, Ardrossan • Catacol Bridge (C147) • Culvert West of Ballymeannoch (C147) 2.12 Given the availability of ferry bookings, programmed works will be restricted to a fixed number of weeks. As a result of this, the programme for Arran will be limited to five weeks. Any works that can’t be completed within that time, will be carried over to a future year’s programme. 2.13 The roads investment funding agreed at the Councils budget meeting on 25 February 2026 will require significant resource to plan, design and deliver the investment in 2026/27. In addition, and similarly with previous years, unforeseen circumstances, like
Page 4
weather events or land slips may have an impact on the delivery of the programme together with the availability of contractors and materials required to complete the programme. Should the service not be able to deliver the full programme in the current financial year, any works not complete will be carried forward into 2027/28. 3. Proposals 3.1 That Cabinet notes the approach taken to determining the asset maintenance programme for roads, structures and street lighting. 3.2 That Cabinet approves the maintenance programme for 2026/27, as shown at Appendix 1. 3.3 That Cabinet notes that the programme will be issued to Locality Planning Partnerships for information. 4. Implications/Socio-economic Duty Financial 4.1 The Roads, Structures and Street Lighting Maintenance Programme will be delivered from approved 2026/27 Capital and Revenue budgets of £8.3m. Estimated costs are detailed within the appendices. Human Resources 4.2 Delivery of the programme will be met from existing staff resources and appropriate contractors. Legal 4.3 North Ayrshire Council has a statutory obligation to manage and maintain its public road network under the terms of the Roads (Scotland) Act 1984. Equality/Socio-economic 4.4 There are no equality implications. The maintenance programme contributes to the Council’s socio-economic duty, as well-maintained roads are essential for the social and economic prosperity of North Ayrshire. Climate Change and Carbon 4.5 Effective programming and management of these assets will assist in reduced carbon associated with mobilisation of unplanned reactive maintenance resources and extends the use of assets in a cost effective and sustainable manner.
Page 5
Key Priorities 4.6 Effective management of these assets contributes to a number of Council plan objectives ensuring that North Ayrshire is well-connected with effective infrastructure and that we maximise resources and provide value for money. Community Wealth Building 4.7 The maintenance programme contributes to Community Wealth Building through community benefits clauses associated with maintenance contracts. It is also the case that a proportion of the maintenance programme is also delivered in-house by the Roads Operations Team and Building Services. Islands Communities Impact Assessment (ICIA) 4.8 The works programme on the Isle of Arran will be limited to a 5-week delivery period. Local stakeholders will be notified once the programme has been confirmed. United Nations Rights of the Child (UNCRC) 4.9 None Consumer Duty 4.10 None 5. Consultation 5.1 The maintenance programme will be shared with each Locality Partnership.

Appendix 2 Condition Assessment and Prioritisation Process 1.1 The Audit Scotland Follow-up report, Maintaining Scotlands Roads published in August 2016 stated that Councils should use their RAMPs to establish long term investment plans for maintaining the road network taking into acount whole-life costing and treatment options. 1.2 As part of the Roads Asset Management process, annual condition assessments are carried out on the public road network as part of the inspection regime. All locations are assessed using a risk based approach. 1.3 Condition assessments are carried out simultaneously with the Safety Inspections in accordance with the pre-determined timescales contained within our Safety Inspection Manual. All faults noted during these inspections are logged within our electronic Routine Maintenance System (RMS). 1.4 For carriageways, to take account of whole-life and different treatment options the carriageway maintenance programme is developed using road asset management principles. Lifecycle planning is at the core of this approach and takes into account, hierarchies, condition and local community priorities. Preventative treatments are used to prolong the life of carriageway surfaces before their condition deteriorates and requires extensive resurfacing. 1.5 The main factors considered are:- • Road Condition – based on detailed visual inspection and the Scottish Road Maintenance Conditions Survey (SRMCS). • Road Hierarchy – this takes account of the strategic importance of the road and is determined from our Local Transport Plan. • Assistance to Council and Community Priorities – this takes account of other priorities such as economic development, access to shops, amenity housing or schools. 1.6 Carriageways and footways are both condition assessed and scored in accordance with the assessment table below. These condition scores, RCI data, road hierarchy information and priorities information as above are utilised through our electronic WDM Scheme Manager to target locations for improvement works in order to optimise investment.

Appendix 2 Assessment Table CONDITION Extent 1 (Acceptable) 2 (Safe but poor appreance) 3 (Minor deterioration) 4 (Major deterioration) 1 - Up to 25% 5 9 13 2 – 25% to 50% 6 10 14 3 – 50% to 75% 7 11 15 4 – 75% to 100% 4 8 12 16 Each location is also reviewed at least once a year depending on its location within the Roads Hierarchy as part of the routine inspection process. 1.7 There are various types of surfacing materials and processes available depending on the particular road type, location and level of existing deterioration. Options available for treatment include preventative measures such as surface dressing and resurfacing options such as screeding, resurfacing (inlay and overlay), depending on the severity of deterioration full reconstruction may be the most effective option. 1.8 The level of investment associated with works can vary depending on restricted working arrangements, traffic management required and the extent of preparatory works necessary to enable resurfacing. There is also an additional uplift for island working of up to 50% for works on Arran and Cumbrae. 1.9 Street Lighting column replacement is prioritised through non-destructive strength testing to determine the level of deterioration associated with the columns. Following testing, columns are categorised within the Asset Management database for road lighting. 1.10 Testing is carried out in accordance with the Institute of Lighting Engineer's Technical Report No.22 Managing a Vital Asset: Lighting Supports as well as UK Lighting Board Code of Practice: Well-lit Highways. 1.11 Once results are input, the database then compares these results against the more general age profile to determine a final list of priority repairs. This produces recommendations in order of priority for both individual units and whole streets or areas. 1.12 Recommendations are generally categorised as Category A through K as follows:
Page 12
Appendix 2 A: Immediate replacement B: Replace urgently or reinspect within 6 months C1: Column Material failure, replace as soon as possible or reinspect within 1 year C2: Bracket failure, sleeve where possible or replace unit within 1 year D: Foundation failure, realign, reinstate and reinspect within 6 months E: Material approaching failure, replace as part of planned maintenance programme or reinspect within 2 years F: Material approaching failure, replace as part of planned maintenance programme or reinspect within 5 years G: Condition reasonable, but age expired and certified insured for 2 year periods until replaced H: Condition reasonable, but age expired and certified insured for 5 year periods until replaced I: Acceptable condition but age expired and insured for 5 years periods until replaced. J: Sound condition but age expired & visually poor (evidence of concrete cracking etc.) K: Sound condition and not age expired – no current requirement for strength structural inspection, visual only at planned maintenance cycle. 1.13 Where non-urgent replacement recommendations (Category F through to J) are on an individual column basis, the data is further analysed to determine a percentage value for recommended replacement numbers against the balance of units in a street. If this figure exceeds 30% then the entire street will be considered for higher prioritisation which will address the design class standard of the street beyond individual replacement for safety reasons only. 1.14 The structures programme is identified based on the structures prioritisation matrix which ranks assets based on a number of factors including its condition, safety, and usage.
