Case Study: Plant Hire Company Cuts On-Site Accidents by 60% with GeoKontrol Speed Zones
Illustrative case study representing typical results achievable by plant hire and construction equipment operators using AutoKontrol GeoKontrol zone-based speed management technology.
Overview
| Detail | Information |
|---|---|
| Sector | National plant hire and equipment rental |
| Fleet size | 210 machines and transport vehicles |
| Equipment types | Telehandlers, dumpers, rollers, loading shovels, 8-wheel tippers, low-loaders |
| Active client sites | 35-50 simultaneously |
| Deployment period | 12 months |
| On-site accident reduction | 60% year-on-year |
| Key result | Major Tier 1 contractor framework agreement secured |
| ROI achieved | Month 8 |
A national plant hire company operating more than 200 machines and transport vehicles across 35-50 active construction sites at any given time was losing major contract opportunities. Three Tier 1 contractors had declined to add the company to their approved supplier frameworks, citing insufficient evidence of on-site speed management. In the same 12-month period, the company had recorded 8 speed-related on-site incidents — none resulting in serious injury, but several classified as RIDDOR-reportable near-misses.
AutoKontrol was engaged to deploy GeoKontrol across the hire fleet and transport vehicles, creating automatic GPS-defined speed zones for every active client site. Twelve months after full deployment, on-site speed-related incidents had fallen by 60%, and the company had secured a framework agreement with a major Tier 1 contractor — directly attributable to its demonstrated speed management capability.
The Challenge
On-Site Speed Culture
Plant hire sites present a unique speed management challenge. Machines are operated by different individuals on different sites, often with limited site-specific induction. A dumper driver who has been working on a 15 mph site may be redeployed the following week to a site with a 10 mph limit in the working area and 5 mph near pedestrian zones. The driver may not be aware of the specific speed requirements, and on busy sites, enforcement by banksmen and site managers is inconsistent.
The company’s incident analysis showed a clear pattern: 6 of the 8 speed-related incidents occurred within the first three days of a machine arriving on a new site. Drivers were defaulting to the speed norms of their previous site rather than adapting to the new environment.
Tier 1 Contractor Framework Rejections
The plant hire industry is increasingly influenced by the requirements of Tier 1 contractors, who set the safety standards for their supply chain. Three separate framework applications had been rejected in 18 months, each citing the same concern: the company could not demonstrate active speed management for its hire fleet on client sites.
One rejection letter was particularly direct: “Your application demonstrates compliance with relevant legislation, but does not evidence active speed management technology on hired plant. Our sites operate 10 mph limits in working areas and 5 mph in pedestrian zones. We require assurance that these limits are physically enforced, not advisory.”
The combined annual revenue opportunity represented by the three frameworks was estimated at £2.4M.
Insurance and RIDDOR Reporting
The company’s employers’ liability and plant all-risks insurance premiums had increased by 18% at the most recent renewal, driven by the RIDDOR-reportable near-miss history. The insurer had also introduced a specific excess for speed-related on-site incidents — £5,000 per claim — which was an unusual and unwelcome development.
The Solution
GeoKontrol Site Zone Architecture
AutoKontrol designed a standardised site zone architecture that could be rapidly deployed to any new client site:
Zone 1 — Site perimeter (entry/exit): 15 mph limit, activated automatically as the machine or vehicle crosses the GPS-defined site boundary. This zone covers haul roads and main circulation routes.
Zone 2 — Working areas: 10 mph limit, covering active construction zones where workers, materials, and other plant are present.
Zone 3 — Pedestrian zones: 5 mph limit, applied to welfare areas, site offices, car parks, and any area designated as a pedestrian priority zone.
Zone 4 — Public road (transport vehicles only): Standard legal limits applied when vehicles are outside all site zones.
The critical innovation for a plant hire operation was the ability to create new zones remotely. When a machine was mobilised to a new site, the site zone configuration was uploaded to the GeoKontrol system before the machine arrived. The driver did not need to be briefed on site speed limits — the machine would physically comply regardless.
Equipment Categories
| Equipment Type | GeoKontrol Configuration |
|---|---|
| Dumpers (6t-9t) | Zones 1-3 (site only — no road travel) |
| Telehandlers | Zones 1-3 (site only) |
| Loading shovels | Zones 1-3 (site only) |
| 8-wheel tippers | Zones 1-4 (site + road) |
| Low-loaders | Zones 1-4 (site + road) |
| Rollers | Zones 2-3 only (5-10 mph cap) |
Phased Deployment
SGH Connect managed the installation across the company’s three main depots and through mobile installation teams who visited active sites:
Phase 1 (Months 1-4): Dumpers and tippers — the vehicle categories involved in 7 of the 8 recorded incidents.
Phase 2 (Months 5-8): Telehandlers, loading shovels, and remaining site plant.
Phase 3 (Months 9-12): Low-loaders and transport vehicles. GeoKontrol zone library built for all 42 active sites at that point.
Client Site Integration
AutoKontrol worked with the company to offer client contractors view-only access to GeoKontrol compliance data for their specific sites. This transparency was a deliberate commercial strategy: it gave contractors confidence that the speed management was real and verifiable, and it differentiated the company from competitors who relied on signage and driver briefings alone.
Results
Safety Outcomes (12 Months Post Full Deployment)
| Metric | Before | After | Change |
|---|---|---|---|
| Speed-related on-site incidents | 8 | 3 | -62.5% |
| RIDDOR-reportable near-misses (speed-related) | 4 | 0 | -100% |
| Site zone compliance rate | Not monitored | 96.8% | Baseline established |
| Client-raised speed concerns | 11 | 1 | -90.9% |
| New site zone deployments (average setup time) | N/A | 2.5 hours | Benchmark established |
Commercial Outcomes
The company reapplied to the three Tier 1 contractor frameworks that had previously rejected its applications. Two accepted the company onto their approved supplier lists. The third scheduled a reassessment. The application included GeoKontrol compliance data from active sites and a demonstration of the zone configuration process.
Additionally, one existing Tier 2 client upgraded its spend by 40% after observing the GeoKontrol system in operation, specifically requesting that all machines supplied to their sites be GeoKontrol-equipped.

What the Fleet Manager Said
“The framework rejections were the catalyst. We were losing work to competitors who had speed management technology and we did not. But the safety improvement is what matters most. When a 9-tonne dumper is being driven by someone who arrived on site that morning, you cannot rely on a site induction talk to keep speeds at 10 mph. GeoKontrol makes it physical. The machine will not exceed the zone limit regardless of who is operating it. That is the only level of assurance that Tier 1 contractors will accept — and it is the only level that genuinely protects the people on site.”

Key Takeaways
- Plant hire fleets face a unique speed management challenge — machines move between sites with different speed requirements, operated by different individuals
- GeoKontrol’s remote zone configuration solves the mobilisation problem — speed zones are active before the machine arrives on site
- On-site speed incidents cluster in the first days after machine mobilisation, when drivers are unfamiliar with site-specific limits
- Tier 1 contractor frameworks increasingly require demonstrable active speed management — signage and briefings alone are insufficient
- Offering client contractors view-only access to compliance data is a powerful commercial differentiator
- The commercial return from framework access can dwarf the direct safety and insurance savings
