What the buyer says

The B55 and B55.2 demolition project at Sellafield involves the controlled demolition and dismantling of the B55 Office Complex and B55.2 Turbine Hall, located within the WAGR complex, down to existing ground-floor slab level. The scope includes soft stripping, asbestos remediation, high-reach mechanical demolition of the structural frame, cladding and reinforced-concrete floors, together with segregation and processing of demolition arisings, backfilling of voids and final site clearance. A key constraint is Substation 65, which is located within the B55/B55.2 structure and must remain operational and be protected from demolition impacts, dust and water ingress throughout the works. Retained basements and associated structures also require protection, while uncertainties associated with ageing structures, buried services, below-ground voids and incomplete historical information must be managed through robust surveys, demolition engineering and risk-informed planning. Overall, the project is intended to provide a safe, demolition-led solution that reduces workforce exposure, removes redundant infrastructure and supports accelerated hazard reduction across the wider WAGR decommissioning programme.
