18. Quality Levels of SUEQuality Level A - Vacuum Excavation: The use of non-destructive vacuum excavation to determine the exact horizontal and vertical position of the utility.Quality Level B - Designating: Employ geophysical methods to designate the horizontal position of the known utilities that lie within the project area. Quality Level C - Surface Feature Survey / Inventory: Assessment of site utilities and correlating this information with existing utility records.Quality Level D - Records Research: Provides a feel for the overall utility congestion and is limited to project planning and route selection. *T-Rex can provide personnel for manhole investigation and collection of utility data to assist in Quality Level C.
