Recently, GeoModel, Inc. conducted an underground utility survey at the Dallas-Fort Worth Airport in Texas. The survey area was west of the westernmost runway and between and at the end of two runways, and was 6470 feet long and included five (5) Navaid Shelter areas.
GeoModel, Inc. used ground penetrating radar (GPR), metal detection, and multi-frequency locators to detect underground utilities. The locations of the buried utilities were marked on the ground with paint and surveyor’s whiskers so as not to interfere with mowing equipment near the runways.
