Title: Technique for screening work requests

Abstract: An entity (18) that maintains facilities, such as buried conveyances (12) screens requests by contractors to undertake work that may potentially impact such facilities by comparing the Global Satellite Positioning (GPS) coordinates associated with the location of the work to the GPS coordinates of each facility. In the event that the work will occur within a minimum separation distance from the facility, then the entity maintaining the facility will dispatch a technician to physically locate and mark the facility.
