Acknowledged
New Programme and Project Partners (PPP) model improves major project delivery at Sellafield.
Conclusion
We asked the witnesses to explain what has led to the apparent improvement in how projects are now being delivered. Sellafield Ltd told us that it was now delivering its largest projects in a new way, which it calls ‘Programme and Project Partners’ (PPP). Under this model, it works closely with four suppliers to deliver a portfolio of projects over a 20–year period – giving them incentives to develop the workforce, avoiding unnecessary costs and improving co–ordination between projects. We were pleased to hear that Sellafield Ltd is optimistic that the PPP model will deliver even better outcomes in future – as the next group of projects will have been entirely delivered under these arrangements.40

It recognised the positive ratings received by key projects from the then Infrastructure Projects Authority, and the gains made in Reference Class Forecasting to improve cost estimates. 3.4 The nationally recognised project delivery entity, the Programme and Project Partners (PPP) model was noted positively in the report: “Sellafield and the Infrastructure and Projects Authority believe that the PPP model has contributed significantly to strong performance on two of its first three projects, and external reviews have also identified a strong internal culture that is adding value to Sellafield.”
