Guidelines for Installation of Buried Utilities in Right-Of-Way

Kentucky receives quite a large number of requests annually for utility companies to bore under roadways to install utilities. These borings range in size from 2" up to in excess of 24". On numerous occasions, the Cabinet is asked to approve non-standard installations which mayor may not warrant installing a casing prior to installing the utility line. Currently, the guidelines available to the permit engineers are somewhat limited in documenting the particular methodologies which dictate when certain procedures are to be utilized. This research effort will review the available literature from other agencies and utility companies to determine the current state of practice for utility construction beneath roadways.
