AGM Site Selection & Documentation


Location, Location, Location. Above Ground Markers (AGM) are used primarily as reference points for In-Line Inspections and tracking sites. One of the major causes for an ILI vendor’s AGM box not triggering or the tracking crew not detecting the pig pass is the location. Our experienced staff, in conjunction with the client’s alignments sheets (as-builts) and the In-Line Inspection tool vendor requirements, will establish AGM sites that will allow the best chance of detection at the required intervals. Each AGM site will be properly located and clearly visible. The documentation of each site will be given to client prior to the PIG run, complete with description, photo, sketch, GPS coordinates (including survey method), and maps that include the track used to access the site.
