Naghashian, M H (2015) Generalised cost benefit analysis for large infrastructure projects: the case of the Channel Tunnel rail link. PhD thesis, University of Birmingham, UK.
Abstract
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. Now, almost 200 years after Napoleon’s death, the world spends nearly $40 trillion (almost £24 trillion) on constructing and upgrading roads, railways, power plants and other infrastructures so as to keep up with demand. Such huge investments require realistic plans, clear deadlines and tight budgets for the best allocation of resources but cost overruns and delays are all too frequent. What exactly causes the cost overruns or delay is difficult to identify, but better planning and focus on the accuracy of the appraisal is one way to reduce the problems. The new model presented herein should prove useful in assisting decision-makers for all large infrastructure projects, and as a foundation for developing an appropriate decision making tool for different categories of projects too, based upon the experience of the Channel Tunnel. This, after all, was a project that the Government had financed through the private sector with high investment risks and significant degrees of uncertainty and had then put out for construction and operation in two different tenders. In spite of never being viable for the private sector, the Eurotunnel Company looks in a better shape now and the tunnel is working properly, but the construction cost and deadlines were clearly exceeded.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
