## Summary

Rhondda Cynon Taf County Borough Council procured civil engineering and highway stabilisation works at the former Graig Ddu coal and quarry tip site (RH077) in Dinas. The site lies on the northern slopes of Mynydd Dinas above Graig Ddu Road. The works are intended to protect the council’s highway assets by replacing failed and distressed highway structures, drainage systems and carriageway. This is a construction project, covering site stabilisation, structural highway works, drainage construction and carriageway replacement. Delivery is in the Dinas area of Rhondda Cynon Taf, Wales, for the council as the public-sector buyer. The requirement is therefore relevant to contractors with experience in civil engineering, highway infrastructure, earthworks and work on challenging former industrial or extractive sites.

The procurement is complete and the contract was awarded to Alun Griffiths Contractors Ltd. It used a below-threshold limited competition. The contract was signed on 16 January 2026 and runs from 19 January 2026 to 13 August 2027. Its value is £3,646,611.54 excluding VAT, or £4,375,933.85 including VAT. The award covers one completed lot and is classified as construction work. The contract is active and uses an NEC4 Engineering and Construction Contract Option C incorporating the X22 clause. The contract includes options for additional purchases or activities under the stated contract terms. The selected supplier is a large construction contractor. The procurement record identifies the council’s requirement and the successful supplier, but does not publish a separate weighting or narrative for the evaluation criteria.

This procurement demonstrates demand from Rhondda Cynon Taf County Borough Council for substantial, technically demanding highway and land-stabilisation delivery. Suppliers seeking to compete for similar work from this buyer would need credible capability in stabilising former coal or quarry sites, earthworks, retaining or replacement highway structures, drainage systems and carriageway construction. Experience protecting live or important highway assets would be relevant, as would the ability to coordinate several interdependent civil engineering activities on a constrained hillside site. Competitors would also benefit from experience administering and delivering NEC4 Engineering and Construction Contract Option C projects, including the X22 clause. The requirement suits established contractors able to manage complex construction risk, programme, site logistics, quality and safety across a major infrastructure works package.
