Lifecycle Cost Analysis of Sustainable Streetscape Projects
In the design and construction of its streets and public spaces, NYCDOT seeks to use designs and materials that are high quality, durable, and cost effective. Currently, the full lifecycle costs and benefits of materials and designs are not considered when assessing NYCDOT capital streetscape projects. To help NYCDOT better understand the full lifecycle costs and benefits of various design and material choices, the Capstone team analyzed data on recent NYCDOT capital projects through two lenses: the current capital budget approach and the lifecycle costing analysis approach. The team conducted research on materials and designs currently used in sustainable streetscape projects in NYC, Chicago, and London. The results of the comparative analysis will be a useful framework for NYCDOT and other city agencies to use to assess future capital projects.
