Enhancing Sustainability in Public-Private Partnership Projects through Bid Selection Model

Sustainability is one of the most critical agendas of the modern governments, and this concept has been applied in various fields including infrastructure development. However, this concept is yet to be extended to infrastructure projects developed through the public-private partnership route. One of the practical approaches for integrating sustainability concept in PPP projects is to include sustainability aspects in the procurement process as this will compel the private sector to devise project proposals that are sustainable. In this study, multi-criteria decision-making analysis grounded on sustainability to evaluate the bid proposal has been proposed. The model is developed using analytical network process (ANP) with indicators that are established on the four pillars of sustainability, namely, economic sustainability, social sustainability, environmental sustainability, and institutional sustainability. The application of the model is then demonstrated by applying in a PPP highway project case study. The developed methodological framework will enhance the sustainability of public-private partnerships. This improvement is by easing and helping the decision-making process of the host government by selecting best and sustainable bid to achieve the goals of sustainable development and to meet the demand of infrastructure through PPPs, in most sustainable way.
