Tenders for the major procurement plan were due to be published last month but progress has slipped with the race now set to start early in the New Year.
Sellafield aims to replace its Infrastructure Services Alliance with Morgan Sindall and Arup with a new Infrastructure Delivery Partnership.
The organisational shake-up will see a new overall strategic partner, supported by three key delivery partners for electrical distribution, utilities, and civils.
The winning firms will oversee £3.4bn 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.
Overall Strategic Partner
Front-end definition and project sequencing services (Spend £252m – £445m)
Three delivery partners
o Civils and general – Deliver work packages related to the road and rail network, pipe bridges and ducts, excavation and general civils work (spend £309m – £534m)
o High-voltage electrical – Deliver work packages related to improving the high-voltage electrical distribution network covering distribution, generation and substations. (spend £680m – £1,156m)
o Utilities – Deliver work packages related to the steam, water, chemical and compressed air networks and general mechanical work (£417m – £995m)
Sellafield Ltd will pay its partner’s actual costs monthly on a fully open-book basis.
Overheads will be paid monthly as a percentage of the defined costs in line with the schedule of costs components.
As part of the competition, tenderers will be asked to submit proposed profit within the ranges of 4%-10% for both the strategic partner and delivery partners.
The overhead cap percentage for the strategic partner is 20% and 10% for delivery partners.
