Morgan Sindall Infrastructure and Arup have been awarded an extension to deliver the remaining term of the Infrastructure Strategic Alliance (ISA) contract by Sellafield Ltd. The ISA is an alliance between Sellafield Ltd, Morgan Sindall Infrastructure and Arup that delivers a programme of infrastructure projects for Sellafield’s aging asset portfolio.

The ISA is one of several long-term strategic supply agreements aligned to the Sellafield acquisition strategy.

Initially awarded in 2012, the ISA is responsible for a £1.1bn contract to provide essential infrastructure assets to the Sellafield site.

Over the past nine years, the contract has played a significant role in supporting Sellafield’s mission, as well as delivering socio-economic benefits across Cumbria.

Simon Smith, managing director for Morgan Sindall Infrastructure, said: “Securing the third term and extension to the ISA contract, is another great opportunity for Morgan Sindall Infrastructure. Alongside our role on the programme and project partners partnership, which is also being delivered on the Sellafield site, we can continue to work with local organisations and the community to help build sustainable local economic growth. Creating greater opportunities for future generations as part of our commitment to being a responsible business.”

Arup’s digital leader for UK, India, Middle East and Africa, Jim Johnson, said: “We are committed to maintaining a positive presence wherever we operate – and as such we look forward to continuing to play a key role in supporting the local economy in the years to come. The extension of this contract is great news and testament to the hard work of all partners in this alliance.”



The contract is primarily aimed at utility assets, such as electricity, water supply and compressed air, bulk chemical storage and distribution, civil infrastructure, the site’s drainage networks and other facilities including roads, bridges, car parks and general buildings. It also includes some non-utility assets such as analytical services facilities, transport systems, flask maintenance plant and emergency management systems.
