Abstract
Evaluating utilities involves generating an acoustic or seismic source signal, communicating the source signal to a first underground utility, moving a receiver through a second underground utility situated in proximity to the first utility, and monitoring for a cross bore involving the first and second utilities in response to receiving the source signal emanating from the first utility as the receiver progresses through the second utility. Utility evaluation may further involve detecting a cross bore involving the first and second utilities using monitoring data acquired by the receiver.
