Kier Group plc ("Kier") and the KierBAM joint venture (KBJV) today announce its appointment by Babcock International Group, on behalf of the MoD's Defence Nuclear Enterprise (DNE), to support the delivery of a c.£600m programme of works at Devonport Royal Dockyard's 10 Dock in Plymouth.
The upgraded 10 Dock facility will provide vital enhancements to strengthen the UK's defence resilience by improving Devonport's capability to support the maintenance and availability of current and future submarine fleets.
Works include major civils infrastructure, including a water retaining boundary structure and nuclear licensed components, alongside extensive engineering works. This includes the construction of buttresses, new subways, and in-situ subway structures, plus the installation of rock anchors, dowels, reinforcement and a multi-tonne caisson.
KBJV is a key delivery partner within Babcock's wider long-term investment programme at Devonport, which will see significant upgrades to infrastructure over the coming decade to meet the evolving requirements of the UK's Royal Navy. The 10 Dock main works is being delivered as part of Babcock's Major Nuclear Capital Programme at Devonport Royal Dockyard.
As an important part of the UK Government's wider Defence Nuclear Enterprise, focused on maintaining the UK's nuclear deterrent and next-generation submarine capability, this project represents ongoing investment in the UK's defence infrastructure and long-term operational requirements.
