GPR scanning requires access to the area being investigated and clear information about the project objectives. Before scanning begins, technicians may need the site location, project plans, scanning area, surface type, and details about the planned work. Information about known utilities, previous construction, or existing drawings can also help provide useful context for the investigation.

The scanning process requires specialized Ground Penetrating Radar equipment operated by a trained technician. The surface should generally be accessible and reasonably clear of debris, equipment, or other obstructions so the GPR antenna can move across the area effectively. Depending on the project, scanning may be performed across concrete, asphalt, soil, floors, walls, slabs, foundations, or other suitable surfaces.

After scanning, the collected data can be analyzed to identify potential utilities, rebar, conduits, pipes, voids, post-tension elements, and other subsurface features. Depending on project requirements, findings may be marked directly on the surface or incorporated into mapping and documentation. Proper site preparation and clear project information help support more effective scanning and better-informed construction decisions.
