ABSTRACT
Department of Transportation (SCDOT) commissioned a research study to investigate the state-ofthe-practice of LCCA across the nation and Canada and develop a comprehensive LCCA approach for SCDOT. In order to identify and quantify factors that need to be considered in developing realistic life cycle cost analysis, a comprehensive literature review of historical data was conducted. To complement the literature review, a preliminary web survey was developed and sent to the State Highway Agencies Departments of Transportations (DOTs) in all 50 States and Canada to capture their current level of LCCA endorsement and implementation. The second and final survey was sent out to State DOT officials that had responded to the first survey in order to gain a deeper understanding of their LCCA practices.
