Subsurface Utility Engineering: A Technology for the 90's

Federal Highway Administration Video VH-305 Subsurface Utility Engineering: A Technology for the 90's New technologies are introduced for locating pre-existing underground utilities in the highway design and construction process. Electromagnetics and sonics are used to designate utility placement without excavation. Vacuum excavation technology is shown for locating with only minor excavation. Data mapping with CAD is used in the design process. Economic benefits and risk management are stressed.
