Why it matters
Without it, misjudged anchor points, undetected defects, improper redirects, or unsafe single rope setups can lead to climber risk and non-compliance with rigging standards.
From design to safety
Design
AI informs anchor point planning
Reads site survey data, VTA notes, and BS 3998 defect tags; computes tie-in options with load path clarity, redundancy, and rescue access, generating a method statement aligned with LOLER. It cross-references existing HSE guidelines and utility clearance constraints to ensure plan feasibility and safe margins before work packs are issued.

Build
Rigging plans and setup guided
Translates initial plans into anchored entry points, highlights compatible hardware, and produces an equipment roster; validates against single rope technique and redirect ranges before mobilising. It also flags potential hardware conflicts, schedules replacement of worn slings, and generates a field-ready rigging plate layout.

Operation
On-site anchor checks and selections
Monitors real-time load, anchor movement, and dynamic deflection; compares with predicted values, flags deviations, and records interim adjustments. It logs each anchor point with GPS coordinates, load cell readings, and daylight condition notes for post-job review.

Maintenance
Post-use inspection data integration
Stores deformation history, corrosion indicators, and thread wear; flags anchor degradation patterns and revalidates tie-in points prior to renewed use. Data ties to the equipment inventory, including serials, inspection dates, and NDT results from previous seasons.

Safety
Compliance and rescue-ready decisions
Verifies LOLER, BS 3998, and utility clearance requirements; documents aerial rescue readiness, wildlife considerations, and temporary exclusion zones. It exports a safety dossier with signed checklists, last inspection stamps, and contingency routes for six-hour operations windows.

Part by part
- 1
tie-in points
- Watch for
- Undetected deformation or loosening in anchor attachments and natural crotches.
- AI action
- Reads load history and visual indicators; prompts anchor re-test or replacement.
- 2
branch diameter
- Watch for
- Branches near specified critical thresholds showing insufficient attachment capacity.
- AI action
- Calculates allowable loads and selects compliant tie-in options.
- 3
defects
- Watch for
- Cracks, decay, or insect-related cavities near potential anchor zones.
- AI action
- Flags defects; recommends avoidance or alternative anchor locations.
- 4
redirects
- Watch for
- Unplanned direction changes that affect load paths.
- AI action
- Evaluates redirect feasibility and updates rigging layout.
- 5
single rope technique
- Watch for
- Incompatibilities between rope type, diameter, and hardware.
- AI action
- Recommends appropriate rope selection and knot/anchor configuration.
- 6
rigging hardware catalog
- Watch for
- Mismatch between hardware ratings and planned loads.
- AI action
- Suggests compliant components and verification steps.
Worked example
Anchor Point Integrity Check Before Dismantle
Illustrative scenario with sample data.
A mid-slope removal requires a secure anchor from an older limb; AI assists selecting a safe tie-in and redirects plan.
Signal in
surveyDate=2026-08-12; branchDiameter=85mm; defectNotes=none; redirects=2; ropeType=dynamic; riggingPlan=Plan-RT1; equipmentInventory=Rope, Slings, Shackles, Rigging Plate; LOLERDue=2027-04-01; VTA=Yes; BS5837=Grade A
System out
anchorPointId=AP-24; recommendedTieIn=AP-24-tree crotch; rope=3/8 dynamic; recommendedRedirects=R-02; action=approve rigging layout and issue work order; safetyPlan=LP-Anchor-RT1; rescueAccess=Ready
Human sign-off: Crew lead approves the final rigging plan and sign-off comes from the supervising arborist before work commences.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline data capture and rule-sets for anchor point selection; align with BS 3998 and LOLER obligations.
Phase 2
Weeks 5 to 8
Pilot on selected sites; collect performance data and update defect signal thresholds.
Phase 3
Weeks 9 to 12
Full deployment across projects; refine alerting and reporting formats for audits.
Where people stay in charge
- All anchor decisions must be signed off by a qualified person with rigging competence and a current NPTC or equivalent qualification.
- AI outputs are recommendations; final anchor choice requires crew leader validation and arboricultural consultant oversight when required by plan.
- Documented audit trail must show date, signer, and reference to BS 3998 or LOLER compliance.
Questions owners and crews ask
What data does the AI read to select anchor points?
It reads branch diameter, defect notes, defect presence, planned redirects, rope technique, and existing rigging layouts to recommend compliant anchors and methods.
Who approves the AI-generated rigging plan?
The crew leader signs off the plan, with oversight from the supervising arborist or contracted rigging supervisor as per project approvals.
Can AI suggest alternative tie-in locations?
Yes, it analyzes loads, attachment capacity, and safety margins to propose viable alternatives where primary points are unsuitable.
How is safety compliance ensured during operations?
AI flags non-compliant points and requires qualified sign-off before work proceeds, aligning with LOLER and BS standards.
