Service Sets

Underground Utility Investigation - A/I/DATA uses electromagnetic detection methods to identify and detect public and private utilities. We provide sketches, scaled drawings, or mapped results to our clients.

Test Hole Excavation - We excavate test holes to determine the exact location of existing utilities. We use a powerful vacuum to extract materials into a holding tank.

Private Utility Marking - Records of private systems are often inaccurate and may not be available. Unless these private systems are marked before excavation, the risk of damage or injury is very high.

Ground Penetrating Radar - GPR is a nondestructive method of scanning the subsurface to locate underground utilities. 

Subsurface Utility Engineering - SUE involves managing certain risks associated with utility mapping at appropriate quality levels.
