Construction Planners

Be aware of overhead obstructions and underground utilities, including electrical lines, water, sewer, gas, telecom, etc.

Definitively mark or warn of overhead lines or low clearances. When digging, call Dig Safe or whichever agency has jurisdiction. Continue to use caution even after underground lines are marked, since errors in marking are common. Be prepared to hand dig when it's getting close.

Use sawhorses, signs, barrier tapes, etc., to indicate obstructions. Take no chances.
