3.1.8 PPP projects span over long durations. Hence it is critical that GPEs select a PPP provider who can deliver on its commitments and work well with the GPE throughout the entire duration of the partnership. The process for selecting the PPP provider should aim at minimising costs to both the public and private sectors while facilitating strong competition to ensure value for money. Excessive bidding costs may increase the costs for the specific PPP project concerned, and limit competition for PPP projects in the long term.
