Testing and observation of structural steel is a specialized field that requires equipment and personnel trained in accepted operating procedures. Observation and testing can occur during or after the erection process for connections that are welded, bolted or between precast elements and the structural frame.
Terracon professionals perform structural steel nondestructive testing in accordance with a number of specification standards. Our personnel are certified by the American Welding Society (AWS) and the American Society for Nondestructive Testing (ASNT). In-house compliance standards specify minimum requirements for certification and testing of Levels I, II, and III personnel for magnetic particle, ultrasonic and liquid penetrant examination.
