5C h a p t e r 2 Introduction This chapter summarizes the work completed to assess the state of the practice around the country on the use of UCMs. The characterization of the state of the practice involved the use of an online survey, follow-up interviews with stakeholders, and online searches.

10 Interview results General Observations During the interviews with state DOT officials, similarities of practices for managing utility conflicts in transportation projects became evident. Many states follow a traditional approach for utility conflict management in which the state DOT sends a set of project plans to utility owners, the utility owners provide markups of their utility facilities (typically on hard copies)
