- The geotechnical asset can be defined as the foundation of every road and highway structure, and the land on and through which the road network is formed.
- Issues can occur where the land itself is inherently unstable, or where engineered works (cuttings, embankments) have failed through the action of weather, accidental over-loading or under-design.
To eradicate the risk to the travelling public and protect utility services means carrying out a full repair that includes civil engineering works to prevent the land from slipping again and the complete reconstruction of the road.
The repairs by their very nature require careful investigation of the ground conditions (boreholes and trial pits) to locate the solid ground which is not slipping, careful design work to determine the civil engineering works (usually piling and retaining walls) to stop the land slipping and create a stable foundation for the road to be built on - often in co-ordination with utility companies whose cables and pipes are placed within the road Charlton Hill construction. The entire process can take typically take 18 months, and usually requires the road to be shut until the works are complete. More often than not, the repair costs are high, costing £ millions. Whilst the engineering complexity and costs should not be underestimated, the less obvious cost of land slips is their impact and burden on Gloucestershire’s economy and the local community whilst the roads are closed (or at very least restricted) for significant lengths of time.
Of this asset 39% of all street lighting columns are greater than 40 years old and therefore beyond their recommended serviceable life. Due to the associated risks attached in having such an “Age Profile” the strategy for the street lighting Capital expenditure from 2019 onwards is :-
- To undertake an annual programme of structural testing, replacing those columns that fail.
- A risk based programme of area wide column replacements (50-75 columns) that have either, known defective materials or have exceeded their serviceable life. As part of this work any new lighting is designed to meet with the recommendations of the latest British Standard. This is achieved by increasing the heights of columns and lamp wattages, rather than increasing the number of street lights.
