An assessment of SCDOT design-build project schedules

Abstract

This project has gathered and analyzed SCDOT design-build project schedule data for the last ten years and attempted to understand if design-build projects are being delivered on schedule, and if not, what factors are contributing to the schedule delays. The need for major transportation projects to be delivered on schedule was identified in SCDOT’s 2018-2020 Strategic Plan, specifically stating that the objective would be to “improve the reliability of the movement of people and goods across the major portions of our road network”, and that the measure would be “on-time delivery of critical interstate-to-interstate interchange improvement projects”. The overall project goal is to identify systems and structures that can be improved to deliver 100 percent of design-build projects on schedule.
