The excavator has visually identified the precise location of the facility or has visually confirmed that no facility is present up to the depth of excavation; 2. The excavator has taken reasonable precautions to avoid any substantial weakening of the facility's structural or lateral support, or both, or penetration or destruction of the facilities or their protective coatings: b. The excavator shall maintain clearance between a facility and the cutting edge point of any mechanized equipment, taking into account the known limit of control of the cutting edge or point, as may be reasonably necessary to avoid damage to the facility. The city of monroe accurately marked the 6-inch steel gas line. Cdm smith did not comply with the requirements within the tolerance zone.
