Civil Underground Utility Locate Verification

Inspection template for verifying 811 utility locate markings, white-lining, spotter controls, pre-digging checks, and excavation depth compliance before civil digging work begins.

Locate Ticket and Work Area Verification

• 811 ticket is active, valid, and available on site
• Planned dig area matches the ticket scope and marked limits
• Work area has been re-marked or refreshed if locate marks are faded or disturbed
• Utility owner responses and special instructions are reviewed before digging
• No unverified utility conflicts are present in the planned excavation path
• Pre-dig briefing completed with crew and competent person

White-Line and Surface Markings

• White-lining clearly defines the intended excavation area
• Locate markings are visible, continuous, and not obscured by debris or traffic
• Marking colors and identifiers are consistent with utility owner markings
• Tolerance zone boundaries are identified and understood by the crew
• Markings remain intact after site access, traffic control, or equipment staging

Spotter and Crew Controls

• Designated spotter is assigned where required
• Spotter maintains clear line of sight to excavation equipment and hazard area
• Crew uses a defined communication method with the operator and spotter
• Operator stops work when locate marks, spotter, or boundaries are unclear
• Crew members understand stop-work authority for utility exposure concerns

Pre-Digging and Exposure Controls

• Mechanical excavation is restricted within the tolerance zone until utilities are exposed or otherwise protected
• Hand digging or vacuum excavation is used where required for utility exposure
• Utility crossings, crossings depth, and known conflict points are identified before digging
• Spoil pile, equipment staging, and access routes do not obscure markings or create added utility risk
• Required PPE for excavation and utility exposure is available and in use
• Weather, soil, or site conditions require a pause or re-check before digging

Depth Check and Excavation Compliance

• Measured excavation depth is within approved limits for the current work stage
• Depth measurement method is documented and repeatable
• Exposed utilities are protected from damage, movement, or load transfer
• Any deviation from the locate plan is documented and escalated
