## Summary

National Highways Limited commissioned enabling works at Castlefield Viaduct in Manchester to support Phase 2 of a public access and greenspace scheme being delivered with the National Trust. The work comprises site investigation, clearance of drainage channels and a full tactile examination of the viaduct structure. It also involves arranging possession and isolation of the live railway so the investigations and examination can be carried out safely. This is civil engineering work on an existing viaduct, rather than a general landscaping or public realm contract. The requirement is focused on preparing the structure and site for the next phase of the scheme; the award covers these enabling activities.

The procurement is complete and a supplier has been selected. National Highways awarded the single lot to Amalgamated Construction Ltd (AmcoGiffen), and the contract is active. The contract was signed on 4 March 2026 and runs from 20 March 2026 to 20 March 2027. Its value is £425,000 excluding VAT (£510,000 including VAT). The works category is viaduct construction (CPV 45221120). The buyer used a below-threshold direct award without competition. The published process data gives no evaluation criteria, so the award cannot be linked to a stated price-quality weighting or scored technical basis.

For suppliers tracking National Highways’ work on existing structures, this award demonstrates demand for targeted enabling and investigation work supporting public access and greenspace improvements. A credible competitor would need to combine site investigation, drainage-channel clearance and detailed tactile inspection of a viaduct, with the capability to plan and manage access, possession and isolation around a live railway. Railway interface experience and robust safety planning are central to this particular requirement, alongside civil engineering capacity to work on an existing structure. The buyer selected a contractor through a direct award without competition, so the outcome does not establish a competitive evaluation model or show which qualifications or experience determined selection. Suppliers can use the scope and scale of this package as a reference point when considering similar work for National Highways.
