Subsurface Utility Locations

We can provide subsurface utility locations for your Subsurface Utility Engineering (SUE) projects. We provide all four quality levels, D through A, for your project:

Quality Level D information comes solely from existing utility records. It may provide an overall "feel" for the congestion of utilities, but it is often highly limited in terms of comprehensiveness and accuracy. Its usefulness should be confined to project planning and route selection activities.
Quality Level C involves locating and surveying visible above-ground utility facilities such as manholes, valve boxes, meters, utility line markers, etc., and correlating this information with existing utility records. The approximate horizontal location is shown between visible structures. When using this information, it is not unusual to find that many underground utilities have been either omitted or erroneously plotted. Its usefulness, therefore, should be confined to rural projects where utilities are not prevalent, or are not too expensive to repair or relocate.
Quality Level B involves the use of electromagnetic, magnetic and/or sonic equipment to determine the existence and horizontal position of underground utilities. Two-dimensional mapping information is obtained. This information is usually sufficient to accomplish preliminary engineering goals. Decisions can be made on where to place structures in order to minimize conflicts with existing utilities.
Quality Level A involves the use of nondestructive digging equipment such as vacuum excavators at critical points to determine the precise horizontal and vertical position of underground utilities, as well as the type, size, condition, and material. It is the highest level presently available. The 3-dimensional utility locations are determined at discrete points. This is also used at proposed structure crossings in order to avoid conflicts.

The end product CAD files or plans may contain any or all of these quality levels.
