Even in the absence of specific evidence it is surely unthinkable to imagine Napolean Bonaparte himself, when considering the potential benefits of invading England, failing to weigh against them the costs of building a tunnel under \(La\) \(Manche\). In the light of the considerable literature of cost benefit analysis (CBA) and by gathering together several analyses that have been performed on the Channel Tunnel in more recent times, this thesis demonstrates that a comprehensive ‘big picture’ CBA framework is missing, and then provides one: a new methodology, represented in Data Flow Diagram (DFD) form, for the generalised cost benefit analysis of large infrastructure projects.
