Chamber and committees

Over the last 5 full financial years there has been the following number of surface repairs on the A90 trunk road:

All transport expenditure supports economic activity and development. This ranges from the maintenance and enhancement of the road, rail, air and ferry networks and our bridges, the impact of our sustainable travel and low carbon schemes, the support for public transport users through concessionary fares, the funding of rail services and bus grants to allow easier access to employment and support to local authorities.

Funds are allocated in line with the 4 priorities within the National Transport Strategy of which Inclusive Economic Growth is a key component and the vast majority of expenditure is around maintaining and running the existing system that is crucial for economic development. However, all transport interventions have impacts across all the 4 priorities and interact with each other and some projects are funded over multiple years and as such, there is no rigorous way of determining which expenditure in any given period has a primary focus on economic development.

There have been no specific studies undertaken over the last five years to access the environmental impact of the A90’s maintenance and usage. As part of the network management contract obligations, the Operating Companies that manage the Trunk Road Network on behalf of Transport Scotland and Scottish Ministers are required to report annually on the progress of landscape maintenance across the relevant units.

All potential schemes for maintenance and improvement works on the Trunk Road Network, including the A90, are robustly assessed for environmental effects by suitably qualified and experienced environmental specialists. The assessments will involve desk studies and ecological field surveys, where appropriate, and will include an understanding of the environmental baseline, potential impacts from the works and the identification of mitigations and best practice measures which are intended to avoid, reduce and where possible remedy adverse impacts.

The assessment of environmental effects is embedded into the design, planning and execution of schemes and throughout the assessment process, key stakeholders such as environmental statutory and non-statutory bodies, local authorities and members of the public are consulted, as appropriate, to inform the decision making and ensure legislative requirements are met.

Our Operating Companies are required to carry out a range of inspections and surveys to assess the condition and performance of the trunk road network. For example, safety inspections are completed at 7-day intervals. These are primarily to identify defects that require prompt attention because they present, or could present, an immediate hazard to road users. Severe carriageway defects, such as some potholes, are classified as Category 1 Defects, which are required to be made safe when identified, following which a temporary or permanent repair must be undertaken as soon as possible and no later than 06:00 on the day following identification. Where a temporary repair has been carried out, a permanent repair is required to be carried out within 28 days. In addition to this

Lesser defects and general deterioration which do not necessitate such an immediate safety-led response are then considered with findings from our annual testing of the road network to determine future maintenance schemes. These schemes may include localised patching repairs or larger structural maintenance schemes, which are then programmed and considered against competing priorities across the Trunk Road Network

There is a total of 140 overbridges and overpasses (including footbridges on the A90 trunk road and within the Aberdeen Western Peripheral Road / Balmeddie to Tipperty Project boundary. All are in an acceptable condition. They are subjected to regular inspections to determine the integrity of the structures and identify any necessary repairs. Transport Scotland's Operating Company, Amey, has ongoing prioritised works at the structures below:

• A90 Glencarse overpass was struck by a vehicle in March 2023 and repairs were completed on 21 December.
• A90 Finavon Bridge sustained storm damage during Storm Babet in October 2023, work has been ongoing to facilitate repairs

As carriageways are designed for a specific period (a ‘design life’) based on the predicted numbers of vehicles passing over that section over a specific number of years, increased traffic volumes (particularly commercial vehicles) can accelerate their deterioration. Traffic volumes on the A90 have risen by 6% over the last five years. This change in traffic has been factored into our most recent calculation of the Road Condition Index which is used to identify where detailed engineering investigations should be focused in order to determine maintenance requirements.

Road safety is of paramount importance to the Scottish Government. The safety performance of the trunk road network is assessed on an annual basis by screening all locations where three or more personal injury accidents have occurred in a three-year period. Alongside accident clusters, accident patterns and rates in the form of Route Accident Reduction Plans (RARP) are also looked at. This ensures that full consideration is given to accidents that may be spread along a corridor. Further investigations are then carried out and, where appropriate, mitigation measures are prioritised for delivery. This robust, evidence-based approach ensures that the funding available is prioritised for those locations with the potential to deliver the greatest casualty accident savings. It is essential that we use the evidence is used in this way to support the delivery of the casualty reduction targets set out in Scotland’s Road Safety Framework to 2030.

From this process the following schemes have been constructed on the A90:

2019-20 – 6

2020-21 – 10

2021-22 – 6

2022-23 – 3

2023-24 - 2

To date, £32.2m funding committed through the Memorandum of Understanding has been spent. A breakdown of this figure, along with explanatory detail, is provided below:

I have asked Alison Byrne OBE, Chief Executive of National Records of Scotland (NRS), to respond. Her response is as follows:

NRS operates an information security governance and assurance structure aligned to ISO 27001 and HM Government security framework.

Personnel are vetted and undertake mandatory security and data protection training. NRS routinely uses data protection impact assessments to identify and address privacy risks. Regular IT Health Checks are completed and vulnerabilities remediated. Security event monitoring and alerting is in place. Risk management, asset controls and reporting processes are used to manage technology risk.

NRS has achieved Cyber Essentials Plus certification and accreditation as a data processing environment under the Digital Economy Act.
