“It's that easy?” remarked a stunned Atanas Atanasov, responsible for process control at Pytengineeringstroy, after the machines were networked via BOMAP Connect in just a few minutes. The installation really did turn out to be as easy as connecting a smartphone to the car by Bluetooth. But how exactly does this work in BOMAP? The GPS receiver is attached to the roller roof with a magnetic base. For smart communication, all you need to do is plug a Bluetooth transmitter into the "Joblink" data interface on the BOMAG roller. Using a standard Android tablet in the universal holder, the operator starts the app, which automatically connects to the GPS and JOBLINK via Bluetooth. The machine is ready for operation within two minutes.

The major improvement and advantage is that BOMAP Connect digitally networks all the machines involved, allowing the control and documentation of a construction project's entire compaction process. Projects are created and evaluated in a web application. A new project can be created with just four mouse clicks. It's even easier when a digital model of the construction site is available. Then, a complete DXF file can be loaded directly into the system.

The roller drivers see the layout of the construction site embedded in Google Maps. All they have to do is log in to the corresponding project with their local tablet. All currently registered participants are displayed in real time and can track each other's positions. One major advantage is that no hardware needs to be installed on the machines for networking purposes. A tablet or smartphone with a data connection is perfectly adequate.

BOMAP Connect proved itself many times over in real-life conditions in Bulgaria. This can be briefly illustrated by two examples: On the second day of deployment, a driver had forgotten his company tablet. With BOMAP Connect, this was no problem because all the data is stored in the cloud. The driver simply used his personal smartphone. On the third day, a pneumatic tyred roller from a different manufacturer was deployed. It took just two minutes to integrate this machine into the network to display the passes. This was possible because BOMAP Connect is an open system that allows machines to be integrated regardless of manufacturer. Only the Joblink interface is currently not available for other manufacturers.

Pytengineeringstroy 's construction management used BOMAP like a navigation device: To start with, the required passes are defined as the target for the respective project. There were eight passes on this road construction project. The central web application transmits the target value to all tablets. The app now offers the roller driver intuitive, visual control over the required number of passes. As soon as they have been reached, the area in BOMAP appears green.

One decisive benefit of BOMAP was immediately recognised by the users: It achieves significantly more uniform compaction results. Without the smart assistance system, the roller marks are usually concentrated in the centre, while the edge areas are neglected. Pytengineeringstroy took drill cores over the entire paving width of 7.5 m for inspection purposes. The results were convincing: thanks to BOMAP, the density was consistently between 98.4% and 99.8%.

With BOMAP Connect, compaction progress can be monitored from the office and documented in easy-to-understand reports. For Pytengineeringstroy, however, documentation was of secondary importance. The company used BOMAP Connect primarily to optimise the pattern during rolling. Based on the experience in Bulgaria, reducing the number of passes by at least 20% is realistic. Fuel consumption and CO₂ emissions also drop accordingly.

The experience on the construction site in Bulgaria confirms the benefits compared to conventional CCC systems: BOMAP Connect is extremely easy to use and can be implemented with very low investment costs. The app itself is available for free in the Google Play Store and runs on any standard Android tablet with a SIM card. Even third-party GPS receivers can be used as an alternative. The components can be interchanged flexibly between machines, and BOMAP Connect offers a suitable solution for increased smart compaction as a scalable service for all operational sizes.

The roller drivers on the Bulgarian pilot construction site were immediately convinced by BOMAP. Although they were a little sceptical because of their experience with previous CCC systems, nobody wanted to be without BOMAP Connect after the first day. And rightly so: For roller drivers like Ridvan Ahmedov, BOMAP Connect makes their work much simpler. Networking, in particular, makes working in a line of machines more relaxed, effective and safe. With a glance at the tablet, the roller drivers can track their colleagues' work, and BOMAP reliably informs them about all machines' rolling patterns at any time. BOMAP Connect gives roller operators full control over their work. Every roller driver agreed: in order to operate BOMAP Connect, all you need to know is how to use a smartphone.
