After the operator completes the locate request, the ticket is processed by computer at Diggers Hotline. The computer analyzes the polygon drawn around the proposed excavation site to identify which members have elected to receive the information. The computer transmits the message to the members via direct dial communication links. Members receive the information on either a teletype printer, FAX, or directly into their own computer.

The information is received at the members’ mapping or screening departments, or in some cases by a contractor responsible for handling the members’ locate requests. Trained personnel review the locate request in comparison with their maps and records. It is their job to decide whether or not the location of the work site is close to existing underground facilities.

Once it is determined that markings are required, the ticket is dispatched to a field locator, who will locate and mark the excavation site with paint, stakes, and/or flags. Members, or their locating contractor, mark facilities according to specific guidelines and color codes.
