Different sectors tend to approach procurement of PFI/PPP projects in largely the same manner. Unlike England where, for example, the PFU might determine that the procurement seek to move from 4 to 2 to 1 bidder, locally guidance such as this has not been developed. Instead, the approach has been guided by the professional advisers appointed to assist the procuring authority during the procurement process; however, as many such advisers have extensive experience of how procurement in, for example, the health sector in England is managed, then local approaches rarely differ. Again, locally between sectors there is rarely much difference. This is most likely because of the CPD's involvement across all sectors.
