## Summary

The procurement process involves a project titled "Reactor Buildings Height Reduction (EXECUTION phase)" initiated by Magnox Ltd. The project falls under the works category in the construction industry. Located in Trawsfynydd, Wales, the project aims to reduce the height of reactor buildings to meet safety standards for subsequent decommissioning activities, addressing long-term commitments of visual impact reduction within the Snowdonia National Park. The procurement method is selective, with a tender period ending on June 27, 2023, and a contract period from November 8, 2024, to November 11, 2027.

This tender by Magnox Ltd for the Reactor Buildings Height Reduction project presents opportunities for businesses involved in construction, demolition, site preparation, concrete work, and scaffolding services. Small and medium enterprises (SMEs) are well-suited to compete in this competitive procedure with negotiation above the threshold. Businesses interested in long-term projects with clear safety and compliance objectives within the construction sector should consider engaging with this procurement opportunity.

## Notice

The existing Reactor Buildings at Trawsfynydd are now life expired and require works to mitigate against further degradation, thus ensuring they remain safe and compliant for subsequent decommissioning activities. In addition there are long term commitments through the Town and Country Planning process to reduce the visual impact the buildings currently have on the landscape within the Snowdonia National Park. The Height Reduction project has therefore been implemented with the objective of reducing the height of both reactor buildings such that they are left in a safe and stable configuration for the next phase of works to decommission the Trawsfynydd site whilst significantly reducing ongoing asset investment demands. The reduction in height will also satisfy the requirements to lessen the visual impact the current full height buildings have within the Snowdonia National Park.
