Koo, D H (2007) Development of sustainability assessment model for underground infrastructure. PhD thesis, Arizona State University, USA.
Abstract
The conceptual establishment for sustainability in this research emphasizes concurrently enhancing environmental, economical and social aspects in urban infrastructure development. It is anticipated that this new concept, the enhancement of sustainability, is going to generate more long-term benefits without compromising the capability of future generations' prosperity. The development of a sustainability assessment model, through suggesting a new methodological assessment approach and decision making process, is the first step in integrating the complicated interrelations of sustainability issues that occur in real practice. The main objective of this research is to develop and implement a modeling framework for enhancing sustainability in urban underground infrastructure. The modeling framework in this research is named the Sustainability Assessment Model (SAM). The SAM framework involves: (1) proposing alternatives; (2) identifying sustainability issues and indicators; (3) applying assessment methods; (4) integrating assessment results and prioritizing alternatives; and, (5) verifying the final decision. The SAM is designed to utilize multi-criteria decision making methods (MCDM), including AHP and WSM, and various quantitative estimation methods for cost, pollution, energy, time, and natural resource depletion as components of the modeling process. In this study, the SAM is demonstrated and validated through a hypothetical case study for replacing an existing watermain system in the City of Scottsdale. Implementation of the SAM can effectively facilitate a project decision making process by simulating multiple scenarios, reflecting the various interests of potentially conflicting stakeholders. The most significant outcome of this research is the attempt at numerical expression and prioritization for future sustainability evaluation from present viewpoints. Application of the SAM may be premature in real world practice mainly because of the use of unreliable and inadequately defined data for future assessment. However, this study and the proposed SAM is surely a step forward in enhancing sustainability in infrastructure development by considering more sustainability issues and providing a more detailed framework than previous research.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
