Locate Utilities
Notify One-Call Services
Mark proposed path with white paint and have underground utilities located before working.
• In the US or Canada, call 811 (US) or 888-258-0808 (US and Canada). Also contact any local utilities
that do not participate in the One-Call service.
• In countries that do not have a One-Call service, contact all local utility companies to have
underground utilities located.
Verify Underground Utilities
Have an experienced locating equipment operator sweep area within 20’ (6 m) to each side of proposed
excavation to verify previously marked line and cable locations. Mark location of all buried utilities and
obstructions.
Locate Overhead Lines
Note location and height of all overhead lines in jobsite and ensure that equipment maintains proper
distance from live lines.
