## Summary

Merthyr Tydfil County Borough Council procured civil engineering and construction works to protect the New/Top Pond Reservoir dam from wave damage. The requirement was installation of a concrete wave-protection wall measuring 1 metre by 510 metres along the dam wall at Top Ponds Reservoir, in Merthyr Tydfil. This is a single works requirement, rather than a supply-only or consultancy opportunity. The buyer is Merthyr Tydfil County Borough Council, a Welsh local authority. The work involves construction on reservoir infrastructure and is therefore relevant to contractors experienced in concrete structures, dam or reservoir works, water-sector civil engineering, and protection of engineered assets from environmental damage. The awarded supplier was McCarthy Contractors (Bridgend) Ltd, based in Bridgend.

The procurement has been awarded and the tender is complete. Merthyr Tydfil County Borough Council used a below-threshold limited competition. The contract was awarded to McCarthy Contractors (Bridgend) Ltd and signed on 19 August 2026. The contract period runs from 20 August 2026 to 2 October 2026, with an active contract status. The awarded contract value is £147,860.45 excluding VAT, or £177,432.54 including VAT. The procurement had one completed lot covering the wave-protection works. The award is classified as works and the activity falls under CPV 45200000, covering complete or part construction and civil engineering work. The published outcome records one selected supplier for the requirement.

This outcome indicates a defined local-authority demand for specialist civil engineering at reservoir infrastructure scale. Suppliers seeking to compete for similar work with Merthyr Tydfil County Borough Council would need credible capability in concrete construction, linear wall installation and works on or beside dams and reservoirs. The requirement also points to the importance of designing and delivering protection against wave-related structural damage, rather than general building work alone. Relevant businesses would benefit from demonstrable experience managing construction in a water-infrastructure setting, coordinating site operations safely, and completing substantial measured lengths of concrete work within a short delivery programme. The selected small and medium-sized enterprise shows that this type of below-threshold limited competition can suit an established regional contractor with appropriate civil engineering capacity and specialist experience.
