Accurate Infrastructure Data, Inc. (A/I/DATA) is a professional service firm and small business established in January 2005 to provide underground utility investigation, subsurface utility engineering, surveying and mapping services to engineers, surveyors, developers, facility managers, and construction industry professionals. Services include subsurface utility infrastructure records research, investigation, field marking, surveying and depiction or mapping of the location of all types of subsurface utility systems. A/I/DATA employs electro-magnetic (EM) based instruments and ground penetrating radar (GPR) to detect underground utilities. Air-vacuum excavation methods are used to safely expose subsurface utilities so that they can be measured and documented.
The services offered by A/I/DATA are modeled on the standard of practice defined in CI/ASCE 38-02, Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data (ASCE 38-02).
