5.7 One Call Access (24/7)

One Call Center Excavator

Practice Statement:

The excavator has access to a one call center 24 hours per day, 7 days a week.

Practice Description:

Utilities service the public needs 24 × 7 and thus should be protected during that same time. Certain conditions may exist that require excavators to work during off-hours (city/road congestion, off-peak utility service hours). Although most excavators are on the job site during regular work hours, they need to be able to call in future work locations after 5:00 p.m. This allows them more flexibility to schedule work and to avoid peak hours of locate requests at the one call center.
