When highway project designs depart from design values found in the Kentucky Transportation Cabinet (KYTC) Highway Design Manual and AASHTO’s A Policy on Geometric Design of Highways and Streets, project managers at the agency must obtain either a design exception or design variance. While designers are more comfortable with exceptions and variances than they were 10 or 20 years ago, some hesitancy remains, especially among the Cabinet’s consultants. Misperceptions about what exceptions or variances entail or about their performance may underlie this reluctance. Exceptions and variances are best conceptualized as formal justifications for design decisions. Project managers merely need …

Kentucky Transportation Center Research Report
State transportation agencies (STAs) strive to deliver highway projects on time and on budget. Utility relocations are frequently cited as a primary reason for delays. This report describes a new approach for enhancing the alignment of utility coordination and design. Researchers crafted this new approach based on the findings of a literature review, an evaluation of how utility coordination milestones and project development milestones are currently aligned at the Kentucky Transportation Cabinet (KYTC), and the experiences of other STAs. KYTC should use this guidance to facilitate implementation of the new approach and an associated Utility Coordination Training and Certification Program. …
