Sellafield starts £3bn hunt for key infrastructure quartet

Sellafield has fired the starting gun on the race to find four top-level key infrastructure partners as part of the ongoing procurement shake-up at the nuclear decommissioning site.

Procurement chiefs aim to replace the present Infrastructure Services Alliance with Morgan Sindall and Arup with a new overseeing team.

The organisational shake-up will see a new overall strategic partner appointed. This firm will be supported by three key delivery partners covering specific electrical distribution, utilities, and civils disciplines.

Firms selected for the new Infrastructure Delivery Partnership will oversee a £2bn-3bn programme of projects at the nuclear site over 15 years.

The Strategic Partner will provide front-end definition and project sequencing services, undertake feasibility studies and initial engineering design.

It will also work on cost modelling to support Sellafield Ltd in production of business cases, support commissioning and embedding capabilities into the business including knowledge transfer into Sellafield teams.

Below the strategic partner, three delivery partners will complete detailed design and all procurement, installation, construction, commissioning and handover activities that form part of delivery.
