Conceptual Definition of a Megaproject Feasibility Analysis Method

Abstract

<p>Infrastructure systems and assets are, worldwide, facing challenges due to aging and increased requirements to serve the growing social and environmental needs. In addition, various frameworks supporting asset replacement decisions have been proposed but they mainly consider dimensions such as structural performance and life-cycle costs. This paper confronts infrastructure renewal problem at a higher level by shedding light to its interface with megaproject development. Through the brief review of two discrete research areas, namely ‘methods for infrastructure project feasibility analysis’ and ‘integrated infrastructure systems modelling’, it seeks to conceptualise a new method that is able to appraise megaproject investments by simulating and measuring the performance of the whole infrastructure network, into which a megaproject is about to be incorporated.</p>
