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. ## CPV classification Demolition, site preparation and clearance work Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/94716dee-1505-4ec8-8246-698813673a94) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
