The selection process was dependant on two factors: the nature of the challenges identified in the data gathering exercise on the Sample Database, and the willingness of the stakeholders to participate in the research.
A list of projects of interest was compiled and assessed for possibility of gaining access to the relevant people in Procuring Authorities, Project Companies, and other key stakeholders. The initial list contained more than 25 projects in order to mitigate the risk of lack of willingness to participate, or lack of access to the relevant stakeholders.
Contacts within the Global Infrastructure Hub's and Turner & Townsend's global networks were identified and engaged to introduce the research and request input into the selected Case Studies. Some stakeholders responded by suggesting other projects, or were not willing to participate in the research, and the Case Study selection therefore evolved and changed throughout the research. It became clear that the greatest challenge was securing participation of the stakeholders. Most of the Case Studies were drafted and developed with the help of one or two stakeholders. Only a small number of Case Studies had the full support of the Procuring Authority, the Project Company, and the lenders.
