Positivist Approach

This paper aims to propose a financial framework based on mezzanine-type debt for financing Sustainable Infrastructure Systems (SIS). In our analysis, an exploratory-type methodology based on a post-positivist approach for describing the financial eco-innovation in the sustainable infrastructure context is used and consequently, the essential framework’s theory is developed, as well as the characteristics and schemes for its functioning. Moreover, the theoretical foundations of financial eco-innovations are analyzed. It was concluded that researchers could benefit from this framework by acquiring a better knowledge of how a mezzanine-debt type could work together sustainability criteria. This paper is expected to contribute to expanding the existing knowledge and expanding funding knowledge frontiers for SIS, as well as contributes to providing a foundation for new research topics. The originality of the proposed framework is intended to establish new ways in order to close the gap between the development of SIS and financing sources using the incorporation of sustainability criteria in the financing process. Thus, the importance of this work is based on the fact that it can be used as an academic support for producing practical solutions.

Investment Valuation

Purpose The purpose of this paper is to develop an investment valuation model using the mezzanine debt mechanism based on blue bonds that explicitly allude to public–private partnerships (P3s) and project finance (PF). Additionally, this study proposes the financial captured value (FCV) theory for measuring how much financial value lenders may capture by becoming sponsors through financing of sustainable infrastructure systems (SIS). Design/methodology/approach The investment valuation model was validated through the Aguas Claras wastewater treatment plant as a case study. Findings The empirical results show that lenders may capture financial value by converting outstanding debt into equity shares throughout the operation and maintenance stage. Furthermore, case study results provide new insights into the implications of the debt–equity conversion ratio on the relationship between the sponsors’ internal rate of return and the FCV. Research limitations/implications The most significant limitation is the lack of primary and secondary information on blue bonds. Thus, robust statistical analyses to contrast results were not possible. Practical implications Researchers and practising professionals can improve their understanding of how mezzanine debt, P3s and PF into an investment valuation model allows financing SIS using a non-conventional financial mechanism. The recommendations will benefit both the academia as well infrastructure industry in bridging the gap between design theory and practice. Originality/value Sustainability components have not been addressed explicitly or combined in the financing’s structuring. Therefore, the investment valuation model could be considered a novel methodology for decision making related to financing and investment of SIS.

Planning Project

Much of the focus on sustainable infrastructure has concentrated on buildings and construction processes. To advance this thinking for other civil infrastructure systems (CIS), this paper outlines a framework that uses a set of proposed indicators to measure the sustainability of chosen infrastructure options and help select the preferred alternative in a multiobjective decision approach. Physically implementing "sustainable infrastructure" involves three life stages for any project: preproject planning, project implementation, and ongoing operations. It is critical to evaluate the sustainability of chosen options in each of these life stages. This research develops two categories of indicators, mandatory screening indicators (MSI) and judgment indicators (JI), and a multilayer approach for incorporating these indicators. A normalization procedure has been adapted to work within the framework to help compare alternatives across a range of indicators and different orders of data magnitude. A hypothetical example using a transmission line corridor is presented to illustrate how the framework can be applied.Key words: indicators, infrastructure, sustainable, environment, decision making, alternatives.

The Impact

To reduce unforeseen disaster risks, infrastructure systems are expected to be resilient. The impact of many natural disasters on networked infrastructures is often observed to follow a localized attack pattern. The localized attack can be demonstrated by the failures of a group of links concentrated in a particular geographical domain which result in adjacent isolated nodes. In this paper, a resilience-based recovery assessment framework is proposed. The framework aims to find the most effective recovery strategy when subjected to localized attacks. The proposed framework was implemented in a lattice network structure inspired by a water distribution network case study. Three different recovery strategies were studied with cost and time constraints incorporated: preferential recovery based on nodal weight (PRNW), periphery recovery (PR), and localized recovery (LR). The case study results indicated that LR could be selected as the most resilient and cost-effective recovery strategy. This paper hopes to aid in the decision-making process by providing a strategic baseline for finding an optimized recovery strategy for localized attack scenarios.
