The council investigated the footway condition outside Alma Street and concluded that it does not meet the standard for intervention based on their inspection regime, which exceeds national minimum standards for safety and maintenance defects intervention. (AI summary)

Cont.;
Society Wales (CSSW) principles (adopted 2018) as identified within the Blaenau Gwent Highways Maintenance Plan (HMP), therefore provides guidance to when developing the council’s approach in accordance with local needs, priorities and affordability.
The Highway Authority deploys Highway Inspector’s to undertake a regime of inspections to monitor the condition and repair needs of the public highway, they have received and passed accredited training programmes for specific competency in highway inspections to allow them to assess the condition of the public highway.
Details of asset hierarchy, inspection and repair regimes are adopted by the Council and implemented. For the purpose of managing maintenance Councils allocate a hierarchy level to each road and footway to establish inspection frequencies and repair regimes. The most significant factor affecting the risk presented to users is the level of use. As no footfall data is available in many situations across the council, officer judgement is used to estimate footfall for different footways in order to apply the CSSW principles.
From a nationally consistent approach the following table gives an indication of the principles adopted by CSSW, as follows;
Code of Practice Footway Network Hierarchy Category CSSW Footway Hierarchy Footfall Level (indicative) City Centre Pedestrian Area FHVHU > 10,000 (15,000 used for calculations) Town Centre Pedestrian Area FH1 5,000 - 10,000 Footway Outside Public Facilities FH2 1,000 - 5,000 Link Footway (between estates / areas) FH3 500 - 1,000 Housing Estate Footway FH4 < 500 Little Used Rural Footway FH5 < 100
Cont.; The footway outside Alma Street, Brynmawr (Lower Alma Street) is considered to have a low footfall and inspected on a 6 monthly basis, the purpose of inspections are to identify defects that have the potential to cause harm to users and to identify defects that require repair in order to prevent escalation of deterioration and increased (avoidable) maintenance needs.
Defect types identified and the intervention levels that are prescribed for each defect category in the footway is a guidance and minimum standards created by considering risk to users, see below; Safety Defects Table Asset Type Defect Type Hierarchy Dimensional Criteria CSSW National Minimum Standard Depth/Height Extent Depth/Hieght Extent Carriageways Pothole CHSR, CH1 and CH2 > 50mm Any Size > 50mm Maximum horizontal dimension greater than 150mm Pothole CH3, CH4 and CH5** >50mm Any Size >75mm Maximum horizontal dimension greater than 150mm Footways Pothole All > 25mm Any Size > 40mm Maximum horizontal dimension greater than 75mm Crack or Gap All > 25mm Any Size > 40mm Maximum horizontal dimension greater than 75mm Trip All > 25mm Any Size > 40mm Maximum horizontal dimension greater than 75mm Rocking Slabs All > 30mm N/A > 40mm N/A Kerbing Dislodged, Loose, Missing, Damaged - Causing a trip hazard All > 25mm N/A > 40mm N/A
Cont.; Blaenau Gwent County Borough Council has chosen to exceed the CSSW national minimum standards for safety and maintenance defects intervention as shown in the Safety Defects table above. A method has been developed under CSSW’s Highways Asset Management Plan (HAMP) project designed to allow all authorities to adopt the risk-based approach recommended by the new code of practice (CoP). Highway Inspections prior to the accident in July 2020 and post accident in January 2021 have not identified defects approaching this standard >25mm. A further assessment on receipt of the Regulation 28 report has been undertaken and although the footway reconstruction has raised paving <16mm (photo’s attached) they are not at a standard that the Highway Authority would intervene or consider a risk to the highway user and as such there are no proposals for BGCBC Highway Authority to take remedial works actions at this location.
Blaenau Gwent CBC is fully commited to the national inspection regime and the importance of it when it comes to preventing accidents across the highways infrastructure.
