Abstract: Infrastructural projects of largescale are essential for overall economic growth and progress of the different segments of the society but their timely delivery is frequently challenged by cost overruns, time delays, and stakeholder conflicts. Although current project management methodologies, such as PRINCE2, PMBOK, and Agile, offer helpful templates, they do not address the particular requirements of infrastructure projects (Flyvbjerg 2014; Project Management Institute 2017). This study thus fills a gap and offers adding value to the scholarship by elucidating and subsequently appraising the best practices necessary for the successful delivery of large-scale infrastructure projects employing in-depth case studies.
