Places on the South of England framework have gone to J Murphy & Sons (Anglia), BAM Nuttall Limited (South East) and Geoffrey Osborne Limited (Wessex).

Renewals and enhancements work under the five-year framework will be worth at least £4bn across the Anglia, South East and Wessex regions.

The multi-discipline framework will deliver projects of varying value, including stations, buildings and civils, electrifications, power, signalling, telecommunications and track.

BAM Nuttall and Geoffrey Osborne already work in the region and have delivered schemes including a 100-hour blockade to replace a life-expired bridge in Wandsworth and the upgrade of Shoreham Viaduct.

Cameron Burns, Commercial Director Southern region, said: “Over the last few years we have made a shift towards working more collaboratively and closer to fewer key contractors, which has allowed us to deliver major improvements for passengers successfully and safely.

“Given that we are delivering in some of Britain’s busiest stations and on some of the most used routes into the capital, our ability to upgrade the railway with minimal impact on passengers is increasingly important.

“We want to build on this success for CP6 and the relationships we have with our suppliers, and we look forward to working with them all going forward.”

John Dowsett, Managing Director for Infrastructure at Osborne, said: “Winning this CP6 framework is highly significant for us – it sees us further strengthening our rail portfolio and continuing to work with Network Rail, who recognise and value the collaborative approach we bring.”

John Murphy, CEO of J Murphy and Sons said: “We are excited to be part of Network Rail’s strategic partnership to deliver CP6.

“This award continues our long partnership with them in renewing and enhancing infrastructure throughout the UK and will give us the chance to work together and drive innovation and improvements.

“It was a real team effort across Murphy, and the framework will leverage our engineering and rail capabilities across our whole business.”

Huw Jones, BAM’s Rail Director said: “This confirmation of our continued involvement allows us to invest with confidence in developing skills, our innovation pipeline and technology.

“We look forward to playing our part, demonstrating BAM’s commitment to creating sustainable solutions that enhance lives – including rail passengers and the communities where we work.”
