Abstract

Methods and apparatus to evaluate a quality of a locate operation performed at a work site of proposed excavation following issuance of the instruction to a field-service technician. An input/output (I/O) interface receives an electronic manifest of the locate operation. The electronic manifest includes geographic information indicating a first location at which the electronic manifest was created. A distance is determined between the first location and a second location at which the locate operation was requested to be performed. One or more indications of a quality assessment of the locate operation are generated based on whether the distance is within or equal to a predefined range.
