Diggers Hotline can process essentially three types of calls. They are:

a) excavation;

b) planning for excavation; and

c) safe working clearance information for overhead lines.

Excavation calls are the most common. There are several variations to the standard excavation call, each of which has an impact on the start date and time, and each of which can be used to solve unique situations or problems.

Another type of call processed by Diggers Hotline is the planning excavation location request. In this type of request, excavation in the immediate future is not intended. Rather, a construction project is in the planning stage, and information on the location of existing facilities is being sought. Diggers Hotline operators will process a planning call in much the same way they would an excavation call. A full description of the proposed job site is required.

Members will respond to a planning notice within 10 days after receipt of the notice by conducting field markings, providing records, and taking other appropriate responses.

Diggers Hotline also takes calls where excavation is not intended, but where aerial equipment will be used near overhead lines. Diggers Hotline will notify its members of these requests. Those members with lines that require more than 10 feet — the minimum safe working clearance from any overhead line — will provide information about safe working clearances within three business days.
