Rice Associates can assist with any large or small utility designating and mapping need. The firm has developed a thorough and flexible process that produces quality results and addresses the specific needs of our clients. The intent of this process is to present a system of classifying the quality of existing subsurface utility data.

Such a process allows the project owner, design engineer, constructor, and utility owner to develop strategies to manage risks caused by existing subsurface utilities in a defined manner.
