Key performance indicators for infrastructure sustainability – a comparative study between Hong Kong and South Africa Available to Purchase

This paper reports on research that investigated perceptions and prioritization of key performance indicators (KPI) for infrastructure sustainability, from a cross section of construction industry stakeholders in Hong Kong and Republic of South Africa. The results show that although there is general agreement on the indicators, there are noticeable differences in stakeholder ranking, which measures their prioritisation of the various indicators. These differences are closely linked to the level of development of the respective country and hence macro‐level priorities in formulating their sustainable development agenda. The most significant agreements are on indicators related to health and safety, while there are significant disagreements on some indicators related to environment, economy and project management and administration. The study provides empirical evidence of such underlying differences. The paper discusses the implications and challenges in addressing sustainability and sustainable development in developed and developing countries. The paper discusses the findings from the two‐country comparative studies and provides validated indicators for infrastructure sustainability. Recommendations are given on the application of these indicators for decision‐support and integrated sustainability appraisal in infrastructure project (SUSAIP).
