Why it matters
Without it, missteps with dumpers, reversing moves, or breached exclusion zones can lead to near misses, service strikes, or unsafe trench activity, delaying progress and risking harm or compliance issues.
From design to safety
Design
AI-assisted safety planning
The system reads the written scheme of investigation constraints, site plans, exclusion zone layouts, and crane and vehicle access routes to validate safe movement logic against HER context and planning conditions.
- Dump truck (Dumper)
- Exclusion zone fencing
- Banksman signals post
Build
Real-time site setup safeguards
It ingests welfare layouts, temporary works diagrams, access points, proximity sensor data, and site telematics to configure safe travel paths, enqueue exclusion zone enforcement, and log setup confirmations.
- Dump truck (Dumper)
- Proximity sensor array
- Rear-view camera system
Operation
Ongoing movement oversight
The AI monitors reversing alarms, CCTV feeds, bankman radio logs, and plan deviations; it cross-checks against the approved movement plan, flags unexpected routes, and generates daily safety summaries.
- Rear-view camera system
- CCTV camera network
- Banksman signals post
Maintenance
Equipment health and records
It verifies sensor calibrations, camera health metrics, proximity sensor drift, and data integrity; it flags maintenance windows, logs post-incident records, and preserves traceable safety histories.
- Proximity sensor array
- CCTV camera network
- Dump truck (Dumper)
Safety
Completed safety assurance and reporting
The system consolidates near-miss data, zone breaches, device faults, and incident strips into a structured safety case; the qualified person signs off with complete audit trails.
- Exclusion zone fencing
- Banksman signals post
- CCTV camera network
Part by part
- 1
Dump truck (Dumper)
- Watch for
- Wheel/axle movement mismatch, rear-end blind spot, or unexpected rotor movement when loading.
- AI action
- Read proximity and rear-camera signals; trigger stop and alert Banksman.
- 2
Exclusion zone fencing
- Watch for
- Fence integrity breach or gate left open near moving plant.
- AI action
- Flag breach; notify supervisor and update exclusion zone map.
- 3
Rear-view camera system
- Watch for
- Occluded camera view when reversing; misalignment of camera to vehicle path.
- AI action
- Cross-check with plan; alert reversing vehicle to slow or stop.
- 4
Banksman signals post
- Watch for
- Missed or miscommunicated signals between banksman and operator.
- AI action
- Prompt operator confirmation request and log signal receipt.
- 5
Proximity sensor array
- Watch for
- Sensor drift or blind spots in dump path.
- AI action
- Trigger automatic slow-down or stop if breach detected.
- 6
CCTV camera network
- Watch for
- Camera blind spots or failure of live feed.
- AI action
- Switch to backup feed and notify site supervisor.
Worked example
Catching a dumper near-miss before earthworks begin (2.5 ha site, Pleistocene finds)
Illustrative scenario with sample data.
Pre-excavation baseline survey and vehicle movement planning reveal a narrowed access lane adjacent to trenches.
Signal in
data: siteArea_ha=2.5; periods_found=3; exclusion_zone_m=4; vehicleRoutes=R1,R2; cameraHealth=OK; proximitySensors= calibrated; banksmanOnDuty=Yes
System out
alert: proximity breach detected on Route R1; action: halt dumper, engage banksman, re-route vehicle; log: near-miss in safety report.
Human sign-off: Project manager reviews incident log, approves re-routing plan, and signs the post-incident safety report.
How to roll it out
Phase 1
Weeks 1 to 4: Baseline
Install sensor arrays, map exclusion zones, train banksmen, calibrate cameras against site plans, and validate data flows into the central safety cockpit.
Phase 2
Weeks 5 to 8: Trial operation
Run live monitoring with a subset of routes, adjust thresholds, refine alerting logic, and document sign-offs by the qualified person.
Phase 3
Weeks 9 to 12: Full integration
Scale monitoring to all plant movements, integrate with work planning systems, and finalize post-incident procedures and archival workflows.
Where people stay in charge
- All safety decisions must be reviewed and signed off by a qualified person responsible for site safety and compliance.
- Keep human-in-the-loop for stop-and-restart commands in critical interactions; AI may recommend but cannot replace the bankman’s authority.
- Data retention and privacy must be governed by the client's heritage and planning consent requirements and aligned with HER policies.
Questions owners and crews ask
What is AI dumper and plant movement monitoring on excavation sites for?
It watches vehicle movement, exclusion zones, and camera feeds, decides safe operation parameters, and generates alerts and records for safety and compliance.
Which roles approve safety alerts and incidents?
The qualified person responsible for site safety signs off on alerts, incidents, and safety reports; the project manager and client may review summaries.
What data feeds does the system use during build and operation?
It ingests exclusion zone maps, vehicle routes, proximity sensor readings, camera feeds, and banksman signals to validate movements.
How are near misses documented?
Near-miss events are captured in the safety report, with route, time, vehicle, and operator details, and reviewed by the project manager and planner.
