Most Relevant Sustainability Criteria for Urban Infrastructure Projects—AHP Analysis for the Gulf States

Infrastructure projects require lifecycle-based assessment, considering the interests of multiple stakeholders concerning the three pillars of sustainability. There has been a heightened curiosity in employing sustainability indicators for gauging the impacts of developmental projects. Even though the literature is abundant on sustainability assessment methods, there is no proper one for the assessment of urban infrastructure projects in the context of Gulf states. Thus, our research intends to fill in this research gap and recommend an incorporated, hierarchically coordinated approach of sustainability indicators to be employed for the sustainability assessment of urban infrastructure development projects. This aim is achieved through a questionnaire survey, by identifying the sustainability indicators related to the infrastructure projects for the cities, in the context of Gulf states. The survey uses the criteria; "Important", "Practicality", "Reliability", and "Relevance" to assess those indicators. Based on expert opinions, the weights of the indicators are approximated through the analytical hierarchy process (AHP) method. Thus, the study proposes an innovative hierarchically defined structure of sustainability indicators fitting for the Gulf context. Further, it informs urban planners and policymakers, particularly in the Gulf states, about the shift in the direction of sustainability of urban infrastructure systems.
