Abstract: The project development process aims to deliver the most appropriate roadway project given its context. Past work has shown that

significant gains are realized when construction expertise is integrated early and throughout the project-delivery process. The Kentucky

Transportation Cabinet has initiated a process that reviews design documents prior to construction to address issues that may result in time

delays and cost increases. However, these efforts are not utilizing a systematic review process that would allow detailed documentation of the

issues identified and provide a lessons-learned database for future use. The study undertaken classifies the constructability issues that typically impact highway construction projects. This paper first identifies the common constructability categories through a national review and

then quantifies the frequency and severity of constructability issues by comment type and category, review year, reviewer, and comment

severity. The paper’s primary contribution to the body of knowledge is the determination that constructability issues are dynamic and change

over time, there is a need for consistency among reviewers, and that team reviews are more appropriate than a single-reviewer approach. DOI:

Introduction

Roadway projects are developed through a phased team process

that ensures the delivery of the most appropriate solutions. Significant benefits (e.g., cost savings, shortened schedules, and...
