Grimshaw takes contract to design £10bn Sizewell nuclear station

Grimshaw has landed the contract to design a new £10 billion nuclear power station at Sizewell, in Suffolk.

CN’s sister title The Architects’ Journal reported the news, which will see Grimshaw work alongside Canaway Fleming Architects and will come as a blow to RMJM – the original architect on the project.

The scheme was one of several key nuclear jobs that RMJM inherited following its acquisition of YRM in December last year.

Despite financial problems, the now defunct practice had kept hold of its nuclear portfolio, including the prize contract to masterplan and design new buildings for the Sizewell C reactor in Suffolk. 

In late 2010 YRM director John Clemow told the AJ that the firm’s work at Sizewell and Hinkley, to which new parent company RMJM remains appointed, would last “for this decade at least”.

In 2011 Mr Clemow outlined the challenges that would be faced by contractors on EDF Energy and Centrica’s Hinkley Point C project in an interview with CN, that has since been awarded to Laing O’Rourke and Bouygues.

In May, the French energy giant EDF began hunting for a new design team to take forward the Sizewell plans and invited a number of practices to bid.

RMJM confirmed it was among them and told the AJ it had submitted its “capability statement for the next phase of work on Sizewell C”.

But this week it emerged that Grimshaw had won the bundle of work covering the main power station site, while Canaway Fleming had bagged the “associated development” package of design work.

RMJM refused to comment to The Architects’ Journal on Grimshaw’s appointment.

Sizewell C will have two reactors each expected to cost £5-7bn to build that will supply enough electricity to power five million homes.

An EDF spokesman said: “EDF Energy plans to undertake initial consultation on Sizewell C by the end of this year.”

Grimshaw statement about Sizewell

“We are delighted to have been appointed by EDF Energy to provide architectural services for the proposed new nuclear power station at Sizewell in Suffolk.

“Sizewell C is of national importance, helping to achieve the UK’s commitment to tackling climate change, while also ensuring the country’s long-term energy security. 

“We believe that infrastructure of this importance should be designed to the highest quality.

“Grimshaw is committed to approaching this exciting and challenging project with this in mind, drawing on our experience in the design of other energy, infrastructure and masterplanning projects.
