A lack of geospatially accurate utility data has caused numerous project schedule delays, cost overruns, and utility dig-in accidents. This report demonstrates the current state of practices within State Transportation Agencies (STAs) for the collection of geospatially referenced as-built utility record data within public right-of-way and quantifies some of the costs and benefits of such practices. It also shows that the benefits of collecting this data outweigh the costs. Barriers to collecting accurate utility data can be overcome through increased awareness of existing practices, partnership and coordination between STAs and utility companies, better data management practices, and a proactive approach to infrastructure investment. The contractor's report, found in this report link, is available for your use.
