Leyrer + Graf: Devices, Dispatch, and Maintenance in One View

The challenge: visibility across 18 locations

Leyrer + Graf is one of Austria’s leading construction companies, with operations spread across 18 locations. At that scale, keeping track of vehicles, machinery, and equipment is not an administrative task. It is a strategic one. Theft risk, maintenance schedules, machine utilisation on large construction sites, and tachograph compliance: every one of these demands real-time data. Spreadsheets and phone calls do not scale.

In 2020, following a Europe-wide market analysis, Leyrer + Graf selected Rosenberger Telematics as its telematics partner. Fritz Preiser, Head of Machinery and Fleet Management, summed up the priorities at the time: “Issues such as theft, predictive maintenance and an overview of the use of machines and equipment on large construction sites are of central importance to us. In addition, competitiveness in the market also plays a decisive role.”

From deployment to first return: immediate proof of value

The investment justified itself almost at once. Shortly after go-live, a recently stolen vehicle was located and recovered, covering the entire year’s project costs in a single incident. The data was already there. The outcome confirmed what Leyrer + Graf had invested in.

Today, Commander monitors approximately 900 light commercial vehicles, trailers, small equipment, lorries, and construction machinery across the company’s sites. 43 trucks transmit tachograph speedometer data directly into the platform, eliminating manual data collection and streamlining driver compliance.

Three operational pillars: device management, scheduling, maintenance

Commander established itself across three core workflows at Leyrer + Graf:

• Device management: the R-SERVICE app gives workshop teams digital documentation of every telematics installation. Stefan Wanko, Head of Workshop in Gmünd, can track the status of every device across every site without a single phone call.
• Scheduling and dispatch: site managers and the equipment management team led by Michael Macho use Commander to assign machines to construction projects, track utilisation, and identify idle assets before they become a cost.
• Maintenance: operating hours, mileage, and event data feed directly into maintenance planning. The goal: predictive maintenance driven by actual machine data, not fixed service intervals.

The R-COCKPIT mobile app became standard equipment for truck drivers and site managers. Access to live vehicle data shifted from the back office to the people who need it most: on-site, in real time.

Works council involvement: monitoring machines, not people

Fleet telematics at scale requires trust. Leyrer + Graf involved the works council early in the rollout. The result: a clear policy. Commander monitors equipment: location, usage, technical status. Personnel data is not collected without explicit approval. That boundary is enforced in the platform configuration, not just in policy documents.

What comes next

Leyrer + Graf is already looking ahead. CO2 footprint tracking and deeper predictive maintenance through sensor data integration are the next development areas. The foundation, clean, continuous data from every asset, is already in place.

Fritz Preiser’s assessment of the partnership reflects the trajectory: “We are extremely satisfied with our collaboration with Rosenberger Telematics. It is a partnership of equals, in which we work together on solutions.”

That is exactly what 900 connected assets and four years of operational data looks like.
