## Summary

National Highways Limited procured works from Southern Gas Network to support bridge deck refurbishment on the bridge carrying The Ridge over the A21 in Hastings. The requirement covered investigations and the diversion or isolation of gas network infrastructure affected by the bridge works. It included a camera survey investigation and a diversion estimate. This is specialist utility and civil engineering support associated with infrastructure refurbishment, rather than general bridge construction. The work is delivered at the A21 bridge in Hastings, with Southern Gas Network acting as the selected utility provider. Businesses relevant to this requirement include gas network operators, utility diversion specialists and contractors experienced in safely isolating or relocating buried infrastructure around major highway structures.

The procurement is complete and was awarded on 29 July 2026 to Southern Gas Network. National Highways used a below-threshold direct award without competition. One lot was completed, and the award is active. The contract was signed on 29 July 2026 and runs from 30 July 2026 to 30 July 2026. Its value is £560,000 excluding gross adjustments, with a gross value of £672,000, in GBP. The stated evaluation route was direct award without competition, so bids were not assessed through a competitive procedure. The requirement formed part of bridge refurbishment works and concerned investigations plus gas diversions or isolations needed to facilitate those works in Hastings.

This outcome demonstrates demand from National Highways for specialist gas-network work that enables highway bridge refurbishment. A credible future competitor would need practical capability in investigating affected utility infrastructure, carrying out camera surveys, designing or delivering diversions, and safely implementing isolations. Experience of working around live gas assets and within the constraints of major road and bridge projects would be directly relevant. Suppliers should also be able to coordinate utility works with the wider highway refurbishment programme, manage safety-critical activities and provide clear technical estimates for investigation and diversion tasks. The selected supplier was a large gas network organisation, indicating that established operational capacity and utility-specific competence were important to this requirement.
