Pedestal location and cable route evaluation criteria may
include issues such as the manhole location in relation to
the pedestal, existing landscape, utilities present, and
excavation costs.
 Notify a utility location service to locate and mark
underground utilities before digging or trenching with
automated equipment. Hand digging does not require prior
identification of utilities.
3. Using a post hole digger or shovel, dig a hole at the designated
pedestal location approximately 4 inches deep and slightly
larger than the diameter of the pedestal base to accommodate
the base and the stake.
4. Dig a trench at least 8 inches deep between the hole and the
manhole, tapering down from the pedestal location.
Hole, trench, and manhole
5. Drill a hole at least a ½ inch in diameter in the corbel of the
manhole as close as possible to the bottom of the trench using a
corbel drill.
6. Drive the stake of the pedestal into the ground at the designated
location until approximately 4 inches of the stake remain above
ground level. Be sure to avoid driving the stake in at an angle;
the pedestal should not be tilted once attached to the stake.
