Toward adaptive infrastructure: the role of existing infrastructure systems

ABSTRACT

Two recent review papers in Sustainable and Resilient Infrastructure have made the case for a step change in the way infrastructure is conceived and delivered. The papers define the term ‘flexible infrastructure’ and provide examples to support a case for transition. The papers present compelling alternative ideas to the current predominant mode of infrastructure development. However, they undervalue many of the advantages of centralized infrastructure systems that underpin city and national infrastructure networks. We provide some examples of the strengths of what might be deemed ‘rigid’ infrastructure and that the concepts of adaptability can directly apply to upgrading these existing centralized, networked systems. In doing so, we contribute to the debate about appropriate advances forward, highlighting the risks of technological optimism and emphasizing the importance of long-term planning and investment.
