Seddon breakthrough with first major Sellafield job

The long-term key delivery partner deal will see Seddon deliver building fit-out requirements across the site under a 17-year deal worth around £175m

It is the fourth major collaborative multi-project procurement framework agreement awarded by the Programme and Project Partners site management team.

The framework includes general construction activities such as: internal walls, ceilings, screeding, flooring, painting and joinery.

John Shannon, divisional director of Seddon Construction, said: “This opportunity will ensure that we can develop long term and effective relationships with other stakeholders, delivering effective outcomes on the Sellafield site, whilst contributing to both the community and regional economy positively.”

Head of supply chain, Project and Programme Partners, Peter Hogg added: “We’re very pleased to announce our fourth long-term work partnership. This company has never worked ‘inside the fence’ at Sellafield before and that’s why the Project and Programme Partners model is different.

“It’s providing opportunities to organisations that we have not worked with before, which can provide innovative solutions to meet our long-term needs.

This collaboration, together with Seddon’s supply chain will ensure enhanced project delivery and increased social impact and economic benefits for our communities.”

The framework has been procured under the partners multi project procurement (MPP) model. This new approach is being taken to encourages long-term collaboration throughout the supply chain, enhanced project delivery, and greater social and economic impact in the West Cumbria region.

As a result of the deal Seddon is planning to open an office in West Cumbria.

Before the Seddon sole supplier award, three other key delivery partner deals were signed off. Further appointments will be announced for work packages covering everything from groundworks and general civils to steelwork and cladding.
