Balfour Beatty Ground Engineering (BBGE), VSL Systems (UK) Ltd (VSL), and Bachy Soletanche (BSL) have united to deliver a range of works including piling, soil mixing, diaphragm walls and plastic cut-off walls.

The trio have combined to form the Geotechnical Sub-Alliance (GSA).

The GSA will create a stable and watertight platform capable of supporting the immense loads associated with the construction of the new nuclear power station, including one of the world’s largest land-based cranes.

The sub-alliance will sit within Sizewell C’s Civil Works Alliance (CWA), which includes Sizewell C along with Balfour Beatty, Laing O’Rourke, and Bouygues Travaux Publics, and which delivers the main civils works on the project.

Vincent Leblois, Alliance Manager, GSA, said: “As the GSA, we bring together a wealth of global capability, sector expertise and experience to the Sizewell C project. We are working very much as one team delivering one outcome on a ‘best for project’ basis through joint decision-making, strong delivery and using the best people for the job.

“Together and as part of the CWA at Sizewell C, we are creating the foundations to power our future, excited to be contributing to the build and completion of this vital investment in new infrastructure for Britain.”

Jane Towse-Laval, Managing Director at Balfour Beatty Ground Engineering, added: “By working collaboratively, we will combine innovation, technical excellence and our collective expertise, laying the essential foundations for the safe and efficient delivery of this nationally significant energy asset”.

Martin Bellamy, Managing Director, VSL UK, said: “By bringing together the expertise of VSL, BBGE and Bachy Soletanche, we are helping create the foundations for a project that will support the UK’s future energy needs for generations to come.”

Dominic Lovelock, Executive Director, Bachy Soletanche, added: “Each partner contributes proven capability in piling, ground treatment and retaining structures, but it is the integration of those capabilities that will unlock programme certainty and quality for Sizewell C, delivered by one aligned, high-performing team.”
