Selection process for resurfacing schemes
Our Highways Service has a selection process to prioritise both road and footway resurfacing schemes and make best use of funds.
Many key considerations influence that process for example, to avoid spending public money on private property, we need to make sure that the location is maintained by the London Borough of Havering.
Also, bulk ordering materials can offer better value for money, so we check that the potential scheme would be longer than 100 metres.
The Council use Artificial Intelligence to gather Road Condition Data to assess the condition of roads against nationally approved guidelines.
The calculations through the Artificial intelligence process generate average condition scores based on the type, frequency and severity of the recorded defects within 200m sections of each road, providing a clearer picture of the condition of the network.
A maximum of 80 percent of the average condition score (decreasing proportionally as condition score decreases) are then applied to the final analysis in a ‘worst first’ priority, along with the remaining 20 percent applied considering the following weighted factors to further prioritise the locations that are most support local communities.
| Factor | Description | Reason |
|---|---|---|
| Weighting applied to maintenance spend | Maximum weighted score of 10 percent decreasing proportionally as the maintenance spend reduces | Reduce burden on reactive budget |
| Weighting applied to roads with shops | 3 percent weighting | Maintain access to frequently visited places |
| Weighting applied to roads with schools | 3 percent weighting | Maintain access to frequently visited places |
| Weighting applied to roads with bus routes | 4 percent weighting | Enable public transportation |
Footway analysis is completed in a similar way, however, rather than the use of Artificial Intelligence the condition data is collected through detailed visual inspections of the footways, again recording the type, frequency and severity of the defects to nationally approved guidelines.
Proposed resurfacing lists
The two lists show which footways and roads have been prioritised through this selection process.
These lists also rank other potential schemes, which may be considered for future resurfacing programmes if funding allows.
Planning of work
Havering Highway Engineers visit each site to validate the merits of each scheme produced through the selection process.
They will also assess the most suitable resurfacing treatment and may reprioritise a scheme for engineering reasons.
The resurfacing work also has to be co-ordinated around planned and emergency utility works.
Subject to budget availability, it may be necessary to make unplanned alterations to the proposed resurfacing programmes.
