A Comprehensive Indicator Review and Social Network Analysis to Develop Conceptual Framework for Sustainable Public Infrastructure

Abstract: The construction sector’s current sustainability frameworks are centered around private buildings, with little consideration for public infrastructure. Therefore, this paper reviews global rating frameworks to address these gaps and examines 629 indicators grouped into quantitative and qualitative categories. To understand how sustainability and resilience indicators relate to one another, Social Network Analysis (SNA) was used, and 113 distinct indicator groups were identified, with a high modularity of 0.975, suggesting weak cohesion among the frameworks and a fragmented approach to evaluations. Thus, a three-level hierarchical framework is developed to select and make decisions about indicators for sustainable public infrastructure in India.
