DIO and Royal Navy mark milestones in major project at Royal Naval Air Station Culdrose
Defence Infrastructure Organisation (DIO) and the Royal Navy have concluded a contract-signing and groundbreaking ceremony for a major construction project at Royal Naval Air Station (RNAS) Culdrose in Cornwall.
This marks the beginning of work on a £99.5M project to replace and refurbish the 820 Naval Air Squadron (NAS) hangars, associated office buildings, and the full replacement of the Engineering Training School (ETS). The contract was awarded to Keir Construction with Mott MacDonald as the designated Technical Services Provider.
DIO and its contractors will deliver the project on behalf of the Royal Navy, with the first phase seeing the construction of a new air Engineering Training School, a new hangar and refurbishment of existing buildings for 820 Naval Air Squadron, the helicopter unit dedicated to protecting the Navy’s aircraft carrier strike groups. The project covers a combination of demolition, new build within the same site footprint, and the refurbishment of existing infrastructure.
Sustainability will be a key feature of the project which will include integrated water-saving measures, Net Zero carbon emissions, solar photovoltaic panels, energy efficient lighting, and air source heat pumps to improve energy efficiency and contribute to carbon reduction.
RNAS Culdrose, a site crucial for Defence, is home to the Royal Navy’s anti-submarine warfare helicopter fleet. RNAS Culdrose also houses the Engineering Training School responsible for Air Engineering (AE) specialist training, delivering fully trained engineers to support Merlin helicopter operations.
Daniel Ross, DIO Programme Director, Major Programmes and Projects, said: “I am delighted that we can celebrate this significant milestone at RNAS Culdrose, marking the next phase of collaboration with our suppliers and the Royal Navy. Building on the sustainable designs already delivered, the project will continue to contribute towards Defence’s Net Zero targets and ultimately enhance our military capability.”
Captain Stuart Irwin, Commanding Officer, Royal Naval Air Station Culdrose said: “This project marks the start of an exciting regeneration and investment in RNAS Culdrose with new, modern facilities. The Engineering Training School is at the heart of our operations to maintain the Merlin helicopter fleet. Our young people, many of whom are just at the start of their naval careers, will learn how to maintain aircraft in a high-tech and modern teaching environment.
“The refurbishment of aircraft hangars and buildings at 820 Naval Air Squadron is another significant investment. It will provide us with more suitable and sustainable places to operate Merlin Helicopter Force now, and into the future.”
Stu Johnston, Deputy Head, Navy Infrastructure and Projects, Senior Responsible Officer, said: “The DIO and Navy infrastructure teams have worked closely to develop what will be hangar and training facilities fit for the 21st Century Royal Navy. The project will reflect our wider sustainability and energy efficiency ambitions. The team has embraced a collaborative and agile approach built on years of hard work by stakeholders.”
Doug Lloyd, Regional Director, Keir Construction, said: “We are delighted to have the opportunity to work with the Defence Infrastructure Organisation and the Royal Navy to deliver these new facilities. We have a wealth of experience in delivering buildings of the highest quality across the defence estate and are proud to be creating this important enabler to the UK’s future defence capability.”
Chris Ackerman, DIO Account Lead for Mott MacDonald, said: “We are really pleased to be working for DIO as their Technical Service Provider and alongside Kier, the Principal Contractor. This project will provide a suite of modern and sustainable infrastructure for the Royal Navy in accordance with the Defence Operational Energy Strategy”.
The project is scheduled for delivery in the spring of 2028.
