Abstract: A system for determining whether a magnetic field associated with an elongate rebar element in a concrete body of a reinforced structural element assembly includes one or more anomalies. The system includes a data-gathering unit having a frame assembly movable relative to the reinforced structural element assembly, and a sensor assembly mounted to the frame assembly. The sensor assembly includes one or more magnetic sensors for sensing at least part of the magnetic field as the sensor assembly is moved relative to the concrete body, to generate magnetic field data defining magnetic flux density of the magnetic field of the rebar element. The system also includes a tracking assembly for generating location data to locate the magnetic field data relative to the concrete body, and a processor for analyzing the magnetic field data and the location data to generate anomaly data describing the anomaly.
