In the era of massive globalization and extensive technological progress, growing academic attention has been given to the practices related to the management of Large Engineering Projects (LEPs), here intended “as large- scale, complex ventures that typically cost US$1 billion or more, take many years to develop and build, involve multiple public and private stakeholders, are transformational, and impact millions of people” [Flyvbjerg, 2014].

By assuming this point of view, it is safe to say that megaprojects somehow contribute in shaping society’s by addressing its needs and potentially facilitating public conditions in specific matters.

These multi-actor and multi- technology constellations [Lehtinen, Peltokorpi & Artto, 2018] are increasing in both number and magnitude, with the peculiarity of developing their own identity in terms of methodologies, practices, purposes, complexity of stakeholders and overall impact.

Therefore, it is easier and easier to imagine megaprojects as not just traditional projects on a larger scale. [Flyvbjerg, 2014].

To investigate the multiple aspect of LEPs, Authors established the MeRIT (Megaproject Research Interdisciplinary Team) aiming to investigate LEPs from different points of view and with the contribution of different disciplines: engineering, economics, business organization, human resource management, jurisprudence, sociology, sustainability, complexity, etc..

This work represent the first output of this interdisciplinary cooperation between members of MeRIT, aspiring to embrace the intrinsic and unavoidable complexity of Large Engineering Projects.
