Abstract

This article presents the results of a case study to compare various performance measures of a sample project in relation to sustainability. The presented case is the construction of an undercrossing bridge designed to reduce traffic congestion and enhance safety at the existing at-grade intersection of a major ring road. Results include input energy and carbon dioxide emissions during construction based on actual data obtained from the site as reported by the contractor. In addition, an analysis of cost breakdown, including materials, equipment, and labor, for major construction activities, such as earthmoving, is provided. Application of sustainability rating using ISI (Institute for Sustainable Infrastructure) ENVISION is presented to allow a comparative analysis on various performance measures, including resource allocation and impacts on natural world. Conclusions of this article enable project managers and sustainability professionals to identify and evaluate challenges and opportunities of similar projects in respect to sustainable development.
