Accugrade GPS Control System

We use a GPS technology to increase our productivity in earthmoving and grading processes. This Control System allows operators to grade more precisely and faster, which translates into higher productivity, lower operating costs, and a well-done work.

SAE (Electronic Monitoring System)

The Electronic Monitorig System was developed internally by the IT team, with the aim of monitoring the development of activities and working hours of workers and teams in real time, reducing access time to performance indicators for strategic decision making. The system, which is available in Portuguese, English, and Spanish, works via smartphone by reading QR Codes affixed to equipment and on workers’ credentials. It works even where there is no internet available, as data can be stored in the phone’s memory and transferred when there is a Wi-Fi or 4G network signal. It improves cost management, productivity control and contributes to environmental sustainability.
