Methods for overseeing and assessing a locate and marking operation. A ticket is received including ticket information regarding the operation, and a first locate technician is dispatched to perform the operation pursuant to the ticket information. A locate manifest is received that includes at least one digital image associated with a dig area in which the locate technician performed the operation. The locate manifest is compared to the ticket information, and a determination is made if the operation is 1) satisfactory, 2) unsatisfactory and requires further quality control assessment and/or at least partial re-performance, or 3) satisfactory but the first locate technician requires coaching. One or more electronic indications of one of 1), 2) and 3) are provided so as to generate an electronic record of a quality assessment of the locate and marking operation.
