Why it matters
Without AI guidance, underground hazards can be missed, leading to strikes on gas or water mains, utility outages, project delays, and audits failing due to inconsistent record-keeping and unsafe practices.
From design to safety
Design
AI checks utility inputs before planning
The AI reads utility maps, permits, and site constraints, validating alignment with design work specifications, and flags conflicts before work methods are drafted. It cross-verifies local authority constraints, drainage lines, and environmental restrictions, ensuring the planting design and hand-cut work methods reflect utility proximity.
- utility maps
- dig permits
- cable avoidance tools
Build
On-site setup with utility awareness
It references gas pipes and water mains data while planning access routes, hoarding layouts, and temporary traffic controls, ensuring coarse planning aligns with utility protection. The system records route testing, access point numbers, and temporary utility shutdown notices.

- water mains
- dig permits
Operation
Live detection during digging operations
The AI-crosschecks tool reads sensor data and map overlays, guiding trenching or stump grinding away from utilities, and prompting adaptive work methods. It logs trench positions, depth readings, and tool paths with geo-tagged timestamps.
- cable avoidance tools
- utility maps
- dig permits
Maintenance
Record-keeping and rechecks mid-job
It logs field readings, updates maps, and tracks permit status, enabling quick revalidation if conditions change or new utilities are encountered. The system issues re-certification reminders and stores version histories for every revision.
- utility maps
- dig permits
- cable avoidance tools
Safety
Safety and compliance sign-off
Qualified persons review detected conflicts, review control measures, and approve changes to protection plans, with records retained for audits and inquiries. The process requires multi-party sign-off including client, utility liaison, and competent person verification.

- Missing or incomplete on-site coordination notes.
- AI action
- AI creates a live coordination ledger and sign-off prompts.
Worked example
Catching a utility conflict before stump grinding
Illustrative scenario with sample data.
A mid-size estate tree removal includes stump grinding near known utilities; AI reviews maps and permits before cutting starts.
Signal in
jobId: EST-402, site: Greenfield, crew: 4, equipment: stump grinder, cableAvoidTip: true, mapsVersion: v3.2, permits: P-UL-19, riskArea: 6m
System out
Alert issued: potential conflict with gas main near planned trench; work plan adjusted; permit conditions updated; save to site file.
Human sign-off: Crew supervisor and utility liaison review the alert, approve the revised plan, and sign off on mandatory safety controls.
How to roll it out
Phase 1
Weeks 1 to 4: Baseline
Install data sources, load maps, permits; configure AI thresholds and alerting for utility avoidance.
Phase 2
Weeks 5 to 12: Integration
Link field data feeds, test real-time alerts on mock sites, train crews on response procedures.
Phase 3
Weeks 13 to 20: Stabilization
Operate in live projects with continuous monitoring, audit trails, and performance reviews.
Where people stay in charge
- Decisions about utility avoidance zones must be approved by the designated site supervisor and, where applicable, the client’s utility liaison.
- Changes triggered by AI must be logged with time-stamped records and sign-offs; maintain traceability for audits.
- All data about critical utilities and permits must be reviewed by a qualified person before any work; unauthorised changes are not permitted.
Questions owners and crews ask
What data sources does AI integrate for underground utility detection?
AI combines utility maps, gas and water line records, and dig permits, plus on-site sensor feeds to build a dynamic, risk-aware plan before any ground disturbance.
Who approves changes triggered by AI detections on site?
The designated site supervisor and utility liaison review AI-triggered changes, ensuring compliance with permits and safety protocols before execution.
How does AI handle outdated utility information?
AI flags map discrepancies, requests updated data from the client or utility providers, and updates the site plan accordingly before proceeding.
What records are kept for audits?
All maps, permits, sensor readings, alerts, decisions, and sign-offs are stored in a project file with traceable responsibilities.
