An Annual Test Point survey is a mandated procedure required by the D.O.T. Pipe-to-soil readings are collected at each test point and above ground structure associated with a given system or structure. This information is vital in the assessment of cathodic protection status for structures such as pipelines, casings, tank bottoms, etc. This survey type can be conducted singularly or coupled with other survey methods such as close interval surveys. North American Survey Corp conducts a thorough survey with data collection readings such as pipe-to-soil, structure-to-soil, AC, foreign line pipe-to-soil, etc. each with corresponding sub-meter GPS and is formatted to meet the operator’s requirements in a timely fashion.
