Maps often lack the precision needed to ensure proper clearance and can sometimes be outdated or even inaccurate, while detailed maps for other areas may have yet to be created. Guida Surveying, Inc. (Guida) utilizes the latest in electromagnetic, ground penetrating radar (GPR), and surveying technology to thoroughly identify and map subsurface utilities so you can move forward with your project with the confidence you deserve.

Utility Locating

Guida utilizes a multitude of detection and location methods in order to efficiently identify subsurface utilities giving our clients more accuracy and assurance than existing maps can typically provide.

Utility Marking

Guida precisely marks located utilities adhering to APWA uniform color codes, allowing our clients to advance on their construction projects without the damage or service disruptions unidentified utilities can induce.

Ground Penetrating Radar (GPR)

GPR is a nondestructive tool allowing Guida’s team to detect non-metallic materials such as plastics, concrete, ceramics and fiber optic cables, using radar pulses to image subsurface structures.

“For every $1.00 spent on utility locating and marking there is an average savings of $4.62.”
