To maximise the economies of scale within the Project, the Authorities will need to determine a level of commonality in the Project documentation (for example, in the Construction Requirements and Service Specifications) and provide a single interface (wherever possible) with the PFI Contractor.
There will be a Change Protocol in the Project Agreement (changes may include for e.g. in service levels, waste tonnages, sites and opening hours). An Authority seeking a Change should pay for it. In requesting a Change, however, the impact on the other Authorities would need to be considered and addressed (as appropriate) by the Authority requesting the Change. There may be grounds where a Change is not feasible, perhaps where this would prejudice the operations of one of the Authorities. An example might be a change in policy/strategy of one Authority which impacts on the individual business cases at financial close of the other [insert number] Authorities. Matters such as these may require a "veto" right for the Authority that would be prejudiced.
A method of dispute resolution will need to be settled in case of disputes arising between the Authorities and a single approach by the Authorities in a dispute with the PFI Contractor.
