Balfour Beatty, Laing O’Rourke and Bouygues Travaux Publics have formed a Civil Works Alliance to deliver the main civil works at Sizewell C in Suffolk.
The agreement brings the three contractors into a single delivery organisation, which will be responsible for extensive areas of the project. These include enabling works and earthworks; marine and tunnelling works; main civils works; and ancillary works, permanent roads and networks.
The three companies are all currently working at Hinkley Point C.
The Civil Works Alliance has been established so that Sizewell C has the role of ‘client participant’. This will allow it to operate a target outturn cost contract model to keep control of schedule and costs.
Earlier in June, the government committed to a £14.2bn investment towards Sizewell C to end years of delay and uncertainty over the project.
Nigel Cann, Sizewell C’s joint managing director, said: “This agreement ensures that our civils programme will be delivered by three companies with deep experience of building to the highest nuclear standards.”
“Hinkley Point C has done the heroic work to restart our industry and is seeing big improvements between the construction of reactor Unit 1 and Unit 2. With our Civil Works Alliance partners, we will use replication and innovation to build on that progress and deliver Sizewell C more efficiently and with improved productivity.”
Preliminary construction work at Sizewell C began in January 2024. It is expected to start supplying power in the mid-2030s.
