Indoor utility location is the process of finding and mapping utility systems inside a building, such as electrical wires, plumbing, gas lines, air ducts, and communication cables. Knowing where these utilities are helps building owners, contractors, and maintenance teams safely manage repairs, renovations, and avoid damage during work.
To locate these utilities, people may use building plans if available, but these are not always accurate. When needed, tools like electronic detectors, ground-penetrating radar, or thermal imaging can help find utilities hidden behind walls, ceilings, or floors.
