Accurate trenching saves time and material. Never begin without utility locates. In short: confirm; position; dig, then complete the remaining steps below.
Step by step
Confirm utility locate marks and the trench plan, and identify spoil placement at least two feet from the edge.
Position the excavator square to the trench line on stable ground.
Dig in smooth passes, keeping the bucket level as you approach grade.
Check depth often with a grade rod, laser or GPS machine control.
Place spoil away from the trench edge to avoid cave-ins.
Install a trench box or other protective system before anyone enters a trench five feet or deeper.
Clean the trench bottom to final grade.
Safety reminders for heavy equipment operators
- Call 811 and confirm utility locates before digging
- Always wear your seat belt: ROPS only protects you if you stay in the seat
- Keep people out of the swing radius and blind spots
- Never operate near overhead power lines without proper clearance
