Abstract

Since 2009, Kentucky has made its 3D design data available as a supplemental reference to bidders through the project delivery process. This research discusses methods for ensuring electronic engineering data (EED) — and specifically the proposed digital terrain model (DTM) — support modern construction management methods at the Kentucky Transportation Cabinet (KYTC). Researchers performed a literature review, surveyed KYTC construction and design staff, engaged with Cabinet staff and industry members to understand the current state of practice, and evaluated quality- related attributes of the EED through case studies. The report presents a set of targeted recommendations for improving KYTC processes of highway design review, training and guidance for Cabinet staff, data sharing and management, professional service contract negotiations, and facilitated communication between KYTC and its industry partners.
