Why it matters
Without AI, inaccurate span data, unpredicted growth, inappropriate clearance intervals, and unplanned outages lead to conflicts with outages, safety risks, and non-compliant planning. These gaps create fails in audits and permit reviews.
From design to safety
Design
AI-assisted planning and risk screening
The AI reads span survey data, growth projections, and line clearance rules to draft initial plans, identify critical interference zones, flag TPO or wildlife constraints for regulatory review. It builds a digital twin of corridor geometry, logs asset attributes, and exports a BS 5837-compliant tree constraints pack for planning committees.
- span surveys
- growth rates
- clearance cycles
Build
Plan execution and mobilisation
The AI translates plans into line outage windows, equipment needs, and crew allocations, cross-checking with asset data and site constraints to produce safe, feasible work packages. It generates MTO grids, assigns MEWP access points, and maps temporary traffic management sections to the plan.
- line outages
- work packages
- span surveys
Operation
On-site optimization and guidance
Real-time signals adjust pruning timing, access routes, and rigging plans; the system records progress, deviations, and safety-critical observations for the permanent log. It captures climate readings, wind thresholds, and target clearance margins per pole.
- span surveys
- clearance cycles
- line outages
Maintenance
Lifecycle data and inspection sync
AI aggregates inspection findings, growth updates, sensor readings, and equipment service records to refresh maintenance schedules and renewal intervals. It tracks LOLER inspection dates, asset replacement timelines, and root protection area re-evaluations.
- growth rates
- span surveys
- data integration
Safety
Regulatory compliance and rescue readiness
The AI ensures aerial rescue procedures, LOLER-compliant equipment checks, and wildlife law compliance are embedded in plans; signoffs come from qualified persons before execution. It confirms NPTC ticket validity, sets retraining reminders, and records SOP compliance for each crew.

Part by part
- 1
span surveys
- Watch for
- inaccurate span length or pole mounting irregularities that affect clearance
- AI action
- read span metrics; trigger updated clearance model and revised work package
- 2
growth rates
- Watch for
- unexpected growth causing enclosure or line contact risk
- AI action
- update growth models; prompt re-forecasted clearance intervals
- 3
clearance cycles
- Watch for
- deviation from approved cycle dates or missed corridor gaps
- AI action
- validate cycle plan; propose adjusted clearance sequence
- 4
line outages
- Watch for
- unplanned outage conflicts with other works or weather windows
- AI action
- simulate outage windows; generate revised scheduling plan
- 5
work packages
- Watch for
- missing crew roles or insufficient equipment in the plan
- AI action
- assemble complete work package with tasks, roles, and tool lists
- 6
data integration hub
- Watch for
- data silos or missing asset records
- AI action
- integrate surveys, sensor feeds, and asset registers for unified control
Worked example
Catching a line clearance task before a storm window
Illustrative scenario with sample data.
Mid-summer corridor assessment identifies growth encroaching a 2.5 m clearance zone ahead of a scheduled outage.
Signal in
survey_id=SV-708, span_length=180m, growth_rate=0.8m/year, outage_window=2026-07-18 08:00-12:00, equipment=MEWP-3, crew=${crewA}, weather=partly_cloudy, accessibility=restricted
System out
generated_outage_schedule: 2026-07-18 08:00-12:00; work_packages: WP-101; PPE: standard; minimum clearance 4.0m; risk_factors: weather_readiness_ok; asset_repair_followups: PR-442 and PR-443 scheduled
Human sign-off: Operations manager reviews schedule and approves outage window and crew allocation before dispatch; site safety officer signs off on risk assessments and rescue readiness.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data capture, asset register clean-up, and integration of span surveys with grading rules.
Phase 2
Weeks 5 to 8
Prototype planning cycles tested against outage scenarios; crew roles and equipment lists validated.
Phase 3
Weeks 9 to 12
Operational rollout with live sessions, incident logging, and post-activity review for continuous improvement.
Where people stay in charge
- All planning decisions must be signed off by a licensed utility arborist or equivalent qualified person.
- All data used for regulatory submissions must be traceable to source documents and asset records.
- All outage plans must align with public protection and utility safety standards; deviations require formal approval.
Questions owners and crews ask
What does AI assist in span surveys for utility projects?
AI analyzes span geometry, pole spacing, and vegetation proximity to produce an accurate corridor model and flag regulatory constraints before planning; it cross-checks against BS 5837 and LOLER requirements.
How are clearance cycles determined by AI?
AI uses growth models, species data, and regulatory setbacks to set clearance intervals and trigger re-survey alerts when thresholds are exceeded; it records justification in the plan file.
How does AI respond to line outages planning?
AI simulates outage windows, checks equipment and crew suitability, and outputs a validated schedule to avoid conflicts and safety risks; it preserves audit-ready trail of changes.
Who signs off final line clearance plans?
A licensed utility arborist or equivalent qualified person signs off the final plan, ensuring compliance with LOLER and NERC/RELEVANT local standards.
