Site-access roads for construction vehicles and six terraced working platforms with a layer thickness of 45cm are currently under construction in the region of the town’s Rauschbart district. The terrain is steep and compaction quality required for the ground is critical; the viaduct pier foundations will eventually be constructed using large-diameter bored piles on these terraces.
Two HC 200i compactors, one with a smooth drum and the other with a padfoot drum, are delivering high compaction performance on the construction site and can also be easily connected to the Smart Doc app via Bluetooth Low Energy for full-coverage compaction control and documentation. The app delivers a visual overview of the most important parameters, such as the number of double passes, rigidity values or the compaction progress so far, directly to the driver’s tablet or smartphone.
Florian Harpf from lead contractor Gfrörer Bau sees this as a way of making the site manager’s work easier. “If one compactor is not operating, I can use the tablet of the other compactor to see and correspondingly record what the driver is doing and whether I, as the site manager, have to intervene or explain something, or it is also possible to check from the office whether the system is recording as it should.”
There is an option for collating the recorded data as a report that can be exported as a PDF and shared. The Smart Doc Connect function also enables process data to be exchanged between several machines. This data can then be tracked live on a browser from any location by real-time cloud communication.
During the work on the Horb Viaduct, Smart Doc also optimised and streamlined on-site work by reducing the number of double passes. “Smart Doc streamlines the construction processes,” said Harpf. “The continuous measurement, documentation and visualisation eliminate the need for the operator to perform load-bearing tests, which can take a good two hours to complete. This saves not only time but money too.”
