Project description

Sellafield Ltd selected Morgan Sindall 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 will be responsible for the infrastructure portfolio, masterplanning and feasibility and design studies across Sellafield. The contract will run for an initial five year period, but could be extended for a further ten years, and plays an important part in driving economic growth across West Cumbria.

The ISA will provide 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



To ensure we promoted local employment within Cumbria we have held three open events in the local area to the Sellafield project. These took place in Workington, Whitehaven and Barrow in Furness. We advertised the events 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 event included a presentation on the project and a chance to speak with a number of employees already working on the Alliance. From this, we have recruited more than 50 local people from West Cumbria to work on the ISA contract, including 10 apprentices and four local graduates.

To develop our relationship with the local supply chain, the ISA has held a series of ‘Meet the Buyer’ events which offered a chance to engage with local companies and extend relationships for future collaborations.


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, and
  • Use of an optimised and flexible delivery team.
