Project description

Sellafield Ltd selected Morgan Sindall Infrastructure and Arup in joint venture as its delivery partner for a potential £1.1 billion contract to provide a range of essential infrastructure asset services to the Sellafield site. The ISA is responsible for the infrastructure portfolio, masterplanning and feasibility and design studies across Sellafield. The contract has recently been extended for a potential further five year period, and plays an important part in driving economic growth across West Cumbria.

The ISA provides a site wide consistent approach to the delivery of infrastructure projects by engaging with a wide range of infrastructure capabilities and knowledge of the latest industry techniques. Through working in close partnership with the customer, the delivery partners will provide a programme management and project delivery service for all infrastructure assets. This includes:

  • Steam generation and onsite distribution
  • Electricity generation and onsite distribution
  • Water supply to site and onsite distribution
  • Compressed air generation and distribution
  • Civil infrastructure supporting pipes and cables
  • Drainage network and sewerage treatment plant
  • Roads, bridges and car parks
  • General building facilities such as canteens and laundry.

The joint venture team will define, manage, construct, commission and hand over a range of projects set out in the ISA Works Programme.
This long-term programme of investment and change on the Sellafield site has been introduced to minimise the risk of production plant downtime due to infrastructure asset degradation. The project requires a fresh approach to the addressing the assets at Sellafield in an effective and efficient manner, paying attention to schedule and cost improvement.

Responsible business

Enhancing communities

Enhancing communities

We are dedicated to promoting local employment within Cumbria and have held various recruitment events over the last five years to support this. These took place in Workington, Whitehaven and Barrow in Furness. We advertised our recruitment campaign in local newspapers and online and had an overwhelming response via telephone, email and foot fall at the actual events. In both Workington and Whitehaven the visitors were in their hundreds and each event saw us leave with around 500 CVs. The events have included a presentation on the project and a chance to speak with a number of employees already working on the Alliance.

In total, we have recruited more than 300 people working on the ISA contract who are local to Cumbria, and will continue to do so to support our programme of works.

To develop our relationship with the local supply chain, the ISA  have held a  number of supply chain ‘speed dating’ events which offer a chance for both national and local organisations to engage with the ISA and tender for works.

Working together with our supply chain

Working together with our supply chain

Working with Sellafield and Arup, we have published the ISA Networking Guide to share the opportunities available, who we currently work with and how other companies can get involved.


In delivering this programme of work, we are striving to meet several challenges. These include:

  • Reduce site risks
  • Deliver a 25 per cent cost saving and 40 per cent schedule / programme saving (as outlined in the ISA business objectives)
  • Reduction in unnecessary work
  • Improved design, estimation and closer alignment with delivery
  • Safe and efficient management of an integrated supply chain
  • Application of standard industry approaches and innovations
  • Use of the market presence and buying power of partner organisations
  • Incentives to drive cost efficiency and cost reduction
  • Scope reduction / elimination and improved scope definition
  • Streamlined systems and processes
  • Use of an optimised and flexible delivery team.
