Identification of Utility Conflicts and Solutions

Potential for conflict with utilities exists in the design of most transportation projects. It is well-recognized that when utility relocation is involved, construction generally takes longer and costs more. Locating and protecting or relocating underground utilities are major causes of delay on highway renewal projects. The state department of transportation (DOT) design development process is focused on solving a transportation need. In most cases, the transportation design proceeds with limited input from the utilities until the design development process is at the 25 to 30 percent stage. DOTs and utilities report the lack of sufficient communication, scheduling, and coordination in the planning, ROW acquisition, design, and construction phases of road construction projects, which in turn inhibit the timely relocation of utilities. Designing to limit the impact of utility relocations is the exception rather than the rule. Identifying and resolving potential utility conflicts early in the design process can minimize the total cost and decrease the time to completion of transportation projects. Some state DOTs have developed forms and tables that identify potential conflicts. For example, the Georgia DOT applies a Utility Impact Matrix to every project involving utilities. Every utility conflict is listed along with a recommendation for resolution, which may include relocating the utility or adjusting the highway design. This matrix is a management tool for identifying potential conflicts and analyzing the best solution for each problem. Utility relocation costs may be reduced by allowing the designer and the utilities to make informed decisions around potential conflicts. The objective of this project is to provide a tool and methodology for identifying and resolving utility conflicts that public agency and utility professionals can use to improve the project development process.
