Abstract

Infrastructure megaprojects are increasing in size and number worldwide. Widespread shortcomings such as cost overruns, delays, litigious threats, and community opposition are now so pervasive there is a clear mandate to rethink the way we plan, deliver, and operate our infrastructure. In this context, we situate this research to understand how megaprojects can be set up for success. Data were collected from responses to a questionnaire survey, interviews, and case studies. The questionnaire was fielded by multiple agencies involved in infrastructure projects, such as engineers, construction organizations, and government delivery agencies. For qualitative insights, we conducted 30 interviews with participants from these agencies and studied cases that successfully implemented the themes identified. The results highlight the three themes with the highest impact in delivering projects successfully: (1) Improved integrated planning, business cases, and front-end engineering design; (2) efficient use of contracts; and (3) strengthening government and political engagement. This research contrasts the literature on megaproject success with data collected from questionnaires, case studies, and interviews. Collecting solutions that have solved issues effectively is an innovative aspect of our methodology, with these findings holding considerable value for ecosystem practitioners. Thus, we contribute by highlighting eight cost-effective, relevant, and efficient ways for reimagining infrastructure megaproject delivery.
